• 看实际读音,不看字母是否为 a, e, i, o, u。
• 中间有形容词时,按形容词读音判断。
| 表达 | 开头音 | 冠词 |
|---|---|---|
| a university | /j/,辅音音素 | a |
| an hour | /ə/,元音音素,h 不发音 | an |
| a useful tool | /j/,辅音音素 | a |
| an honest student | /ɒ/,元音音素,h 不发音 | an |
| a European country | /j/,辅音音素 | a |
| an unusual experience | /ʌn/,元音音素 | an |

• 现场可辨
• 后文限定到具体对象

The Language Exchange Programme allows students in pairs to communicate in two different languages they wish to share and learn each week. Students record short entries after each partner meeting noting the language skills practised and the topics discussed.
句中 the language skills practised 和 the topics discussed 体现了 the 的特指用法。这里采用了“the + 名词 + 后置定语(过去分词短语)”的结构,由 practised 和 discussed 限定了范围,指代的是学生在每次会面中实际练习的技能和讨论的话题。全句意为:学生在每次伙伴会面后记录简短条目,注明所练习的语言技能和所讨论的话题。
•Students sign up and indicate the languages they can share and languages they are interested in learning
句中 the languages they can share 体现了特指。此处 the 修饰 languages,并由后置定语从句 they can share 进行限定,特指“学生能够分享的那些特定语言”。在 and 连接的并列结构中,the 可在首项出现而后续省略,不影响指代一致性。全句意为:学生报名并注明他们能分享的语言以及他们感兴趣学习的语言。
the 的常见结构
the 用于特指或独一无二的事物。
• 独一无二的事物前
• 序数词和形容词最高级前
• 某些乐器名称前
• 江河海洋山脉及部分国家名称前
• the + 形容词:表示一类人,作主语通常用复数谓语
• 形容词最高级前已有 my 等限定词,不用加 the
• 副词最高级前 the 有时可省
| 结构 | 例证 | 表达意义 |
|---|---|---|
| the + 独一无二的事物 | the sun; the moon | 唯一对象 |

我们练习得越多,就越有信心。
泛指类别的三种形式
表示整个类别可用不带冠词的复数名词、a/an + 单数可数名词,某些概括物种或发明的表达也用 the + 单数可数名词。不可数名词泛指时通常不用冠词。三种类别表达并非在所有句子里都能互换,尤其谈物种整体濒危时,不宜机械改成 a/an。
| 所指范围 | 表达形式 | 例子 |
|---|---|---|
| 集合或整个类别 | 复数名词 | Dogs are intelligent animals. |
| 任一个或典型代表 | a/an + 单数可数名词 | A tiger can run very fast. |

零冠词的常见场合
零冠词即名词前不加 a/an/the。

• 人名、城市名、语言、学科、三餐、球类棋类用零冠词;特指用 the。
• 三餐被修饰或表示具体某顿饭时,用 a/an。
• school 等表示求学常规功能时用零冠词;表示具体建筑用 the。
| 范畴 | 零冠词例 | 特指或具体化 |
|---|---|---|
| 学科、语言 | learn physics | the physics taught here |
| 三餐 | have dinner | have a big dinner |
| 球类、棋类 | play football | the football on the desk |
| 学校 | go to school | go to the school |
| 课堂 | be in class | be in the classroom |

Though these new friends were abstract painters using oil paints, or were printmakers or sculptors, I took oil painting as the taboo (禁忌) high form I wasn’t allowed to practice.
句中 oil painting 前不加冠词,是因为它在此处泛指“油画”这一艺术活动或类别,而非具体的某幅作品。在英语中,表示学科、运动或艺术形式的不可数名词在泛指时通常使用零冠词。全句意为:尽管这些新朋友有使用油画颜料的抽象画家,也有版画家或雕塑家,但我一直将油画视为一种我不被允许实践的禁忌的高级形式。
有无冠词改变意思
固定搭配必须整体记忆,不可随意增删冠词。
• 有些表达加不加 the 意思不同。
• 不可数名词在特定短语中可与 a 连用,如 have a good knowledge of。
• 不能由此推出该词所有用法都可数。
| 表达一 | 表达二 | 意义区别 |
|---|---|---|
| in front of | in the front of | 在外部前面;在内部前部 |
| in charge of | in the charge of | 负责;由……负责 |
| at table | at the table | 在进餐;在桌旁 |
| out of question | out of the question | 毫无疑问;不可能 |
| a number of | the number of | 许多;具体的数量 |
老师负责这个社团,这个社团由老师负责。 A number of applications have been received, but the number of accepted students is small.
申请数量很多,但录取的学生人数很少。 With so little time left, completing the experiment was out of the question.
剩下的时间太少,完成实验是不可能的。
序数词前不一定用 the
序数词前不一定用 the,具体取决于表达的是“确定顺序”还是“又一个/再一次”。
• the + 序数词:表示确定顺序中的第几个
• a/an + 序数词:表示又一个、再一次
• 例外:已有物主限定词时不加 the(如 my first lesson)
• 注意:特指与否由句意决定,而非名词出现次数
| 意思 | 结构 | 例子 |
|---|---|---|
| 确定排序 | the + 序数词 | the third day |
| 再一个 | a/an + 序数词 | a third chance |
| 已有限定词 | 限定词 + 序数词 | my third attempt |

语法填空的小词判断
名词前若无限定词,需判断是否补冠词。
• 单数可数名词:泛指填 a/an,特指填 the。
• 复数或不可数名词:特指填 the。
• 例外:已有 this、my、each 等限定词,不加冠词。
• 判定:冠词与介词、代词的判断必须放回完整句子,不可见名词就填 the。
| 判断线索 | 冠词选择 | 例子 |
|---|---|---|
| 单数可数名词泛指 | a/an | a solution |
| 对象已经确定 | the | the solution we discussed |
| 复数或不可数名词特指 | the | the water in the bottle |
| 前面已有限定词 | 不再加冠词 | my answer; these books |
| 固定搭配 | 按整体记忆 | in the morning |

- 不可数名词泛指时直接使用,特指且范围已确定时用 the。
- a bottle of、a piece of、a kilo of等计量结构中,a 修饰的是 bottle、piece、kilo 等可数名词。
- a little、a bit of是数量表达,a 在这里不是直接限定不可数名词的普通不定冠词。
- have a headache、make a mistake、do a favor 等固定搭配允许在不可数名词前出现 a。
- 固定搭配不能反推原名词在所有语境中都可数。
| 使用情况 | 形式 | 例子 |
|---|---|---|
| 泛指 | 不可数名词原形 | Information is important. |
| 特指 | the + 不可数名词 | the information in the file |
| 计量 | a + 可数量词 + of | a bottle of water |

📌 北京真题 2 题原卷原题,答案按官方解析;单项填空 2 题
The biggest whale is blue whale, which grows to be about 29 meters long—the height of 9-story building.
A. the; theB. a; aC. a; theD. the; a
看答案
✅ D. the; a(定冠词与不定冠词)
观察句子结构,首空 blue whale 指代蓝鲸这个物种,在英语中习惯用 the + 单数名词来表示一类事物,故填 the。次空 9-story building 仅是作为长度对比的参照物,表示“任意一栋”九层楼,属于泛指,故填 a。综上选 D (the; a)。最容易误选 A,因为误将后半句的参照物当成了特指的某栋建筑。
First impressions are the most lasting. After all, you never get second chance to make first impression.
A. a; theB. the; theC. a; aD. the; a
看答案
✅ A. a; the(不定冠词与定冠词辨析)
观察句子,两个空格后均接可数名词单数。第一个空格指“第二次机会”,在所有机会中泛指其中一个,用 a。第二个空格中,虽然 first 是序数词,但此处指“(任何一次)第一印象”,且 make the first impression 是习惯用法,强调的是那个唯一的、决定性的初次印象,故用 the。因此选择 a; the。最容易误选 C,因为误以为 first 前必须用 a 来泛指,而忽略了此处强调的是特定性质的“第一印象”。
⚠️ 易错点
- a/an 看音素而非首字母:a university、an hour 都正确。
- 不可数名词不是一律不能加 the:the information you need 是特指,可以用 the。
- 序数词前不总是 the:a second try 表示再尝试一次,my first try 前也不再加 the。
- 不要在 my、this 后叠加冠词;my a book 和 this the room 都不成立。
- 名词后有定语不自动决定用 the:a person who can help 仍可表示任意一位能帮忙的人。
- 三餐、学科、运动的一般活动义常用零冠词,但一顿丰盛的午餐是 a big lunch。
✏️ 自测 5 题

- 填 a/an/the:This is my second attempt; I hope I will not need ______ third attempt.(再试一次)
看答案
✅ a a third 表示又一次,并非强调已确定顺序中的第三次。

📌 北京真题 4 题原卷原题,答案按官方解析;单项填空 2 题;语法填空 2 空
It was hard for him to learn English in a family, in which of the parents spoke the language.
A. noneB. neitherC. bothD. each
看答案
✅ B. neither(不定代词辨析)
首先分析句子结构,in which 引导定语从句修饰 family,空格处作从句主语。关键词是 the parents,明确指代父母两人。根据前文 It was hard(学习很困难)可知,父母应该都不懂英语,因此选择表示“两者都不”的 neither。both 和 each 表示肯定含义,与语境矛盾。最容易误选 A,虽然 none 在语法上也可指代两人,但在指代明确的两者时,neither 更加地道且符合英语表达习惯。
The employment rate has continued to rise in big cities thanks to the efforts of the local governments to increase .
A. themB. thoseC. itD. that
看答案
✅ C. it(人称代词指代单数名词)
首先分析句子结构,空格位于动词 increase 之后,需填入宾语。根据语境,政府努力增加的是句首提到的 The employment rate(就业率)。由于 employment rate 是单数名词,因此必须使用单数代词 it 来指代。最容易误选 A 选项 them,因为学生容易将 big cities 或 local governments 误认为指代对象,但逻辑上增加的是“率”而非“城市”或“政府”。
I know I will whisper to (I) the two simple words “Be yourself”.
看答案
✅ myself(反身代词)
介词 to 后指回主语 I,用反身代词 myself。
Since people can’t always eat out or cook for (they), they get takeout or order delivery.
看答案
✅ themselves(反身代词)
介词 for 后作宾语并回指 people,用反身代词 themselves。
⚠️ 易错点
- 介词后一般用宾格,between you and I 应改为 between you and me。
- her book 中 her 带名词,The book is hers 中 hers 不带名词,不可写 hers book。
- 反身代词须有合适的照应对象;Myself went home 不能代替 I went home。
- 比较两个地方的空气可用 that 替代 air,不可用 one 替代不可数名词。
- 表示“两者都不”用 neither,表示“三者及以上都不”用 none;not all 通常只是并非全部。
- others 后不能再接复数名词;other students 和 others 都正确,但 others students 错。
- each of 正确,every of 错;后者须改为 every one of。
- some 也能出现在邀请式疑问句中,any 也能在肯定句中表示任何一个。

04 数词数量用基数,顺序用序数,倍数先分总量与增量。
📝 北京怎么考:数词是北京阅读信息定位、数据理解与写作表达的基础,不宜把文中出现数字算成独立数词设空题。
基数词的读写
基数词用于表示数量,重点在于拼写细节与大数分级。
• 区分 -teen(十几)与 -ty(几十):thirteen/thirty, fourteen/forty, fifteen/fifty, eighteen/eighty。
• 21—99 非整十数:十位与个位间加连字符(-)。
• 百位后接十/个位:英式加 and,美式可省。
• 大数读法:每三位一组,由右至左依次为 thousand, million, billion。
| 类别 | 数字 | 正确形式 |
|---|---|---|
| teen 结尾 | 14 / 15 / 18 | fourteen / fifteen / eighteen |
| ty 结尾 | 40 / 50 / 80 / 90 | forty / fifty / eighty / ninety |
| 非整十数 | 58 | fifty-eight |
| 百位 | 306 | three hundred and six |
| 千位 | 2,450 | two thousand four hundred and fifty |
| 百万 | 1,000,000 | one million |
| 数字 | 读法 |
|---|---|
| 100 | one hundred |
| 15,000 | fifteen thousand |

序数词与顺序表达
序数词表示顺序,基本规则是末尾加 -th。
• 复合数:仅最后一个数词变序数。
• 表达方式:the first lesson 或 Lesson One。
• 限定词:已有 my 等词时,不再加 the。
• 日期:写 May 1,读 May the first 或 the first of May。
• 缩写:11th, 12th, 13th(看最后两位)。
| 基数 | 序数 | 缩写 |
|---|---|---|
| one | first | 1st |
| two | second | 2nd |
| three | third | 3rd |
| five | fifth | 5th |
| eight | eighth | 8th |
| nine | ninth | 9th |
| twelve | twelfth | 12th |
| twenty | twentieth | 20th |
| twenty-one | twenty-first | 21st |
| one hundred and eleven | one hundred and eleventh | 111th |
| 场景 | 表达 | 说明 |
|---|---|---|
| 表示第一 | the first lesson | 序数词前有 the |
| 表示排名 | She was the first. | 序数词单独作表语 |
| 表示编号 | Lesson Two | 标题或编号中首字母大写 |
| 表示日期 | May 1 / May 1st | 读作 May the first |
| 表示顺序 | the first three chapters | the 后接序数词和基数词 |

五一节是中国的一个法定节假日。 She came third in the final race.
她在决赛中获得了第三名。 Lesson Two begins with a short story.
第二课以一个短故事开始。 Her twenty-first birthday falls on the third of June.
她的二十一岁生日在六月三日。
分数、小数、百分数
分数用“基数词(分子) + 序数词(分母)”,百分数用“数词 + percent”。
• 分子 > 1 时,分母加 s。
• 例外:1/2 读 a half,1/4 读 a quarter。
• 小数点读 point,点后数字逐个读。
• percent 不因数字大于 1 而加 s。
• 分数/百分数 + of 作主语,谓语随 of 后名词的数变化。
| 类型 | 写法 | 读法 |
|---|---|---|
| 分数 | 1/3 | one third / a third |
| 分数 | 2/3 | two thirds |
| 分数 | 3/4 | three quarters |
| 小数 | 0.25 | zero point two five |

约百分之二十的申请者被拒绝。 We waited for two and a half hours.
我们等了两个半小时。
倍数的三种常用句型
表达 A 是 B 的几倍,首选 as...as 或名词结构。
• 句型1:倍数 + as + 原级 + as
• 句型2:倍数 + the + size/length/height/weight 等 + of
• 句型3:倍数 + 比较级 + than(易产生总量与增量歧义,写作优先用前两种)
• 数量词:1倍用 once,2倍用 twice,3倍及以上用 three times 等
| 结构 | 例句或含义 |
|---|---|
| A is three times as long as B. | A 的长度是 B 的三倍 |
| A is three times the length of B. | A 的长度明确为 B 的三倍 |
| A is three times longer than B. | 高中常见,但可能产生“长三倍”或“是三倍”的歧义 |
| 比较对象 | 常用搭配 | 例句 |

总量、增量与百分比变化
区分 increase to(增加到)与 increase by(增加了),明确总量与增量的关系。
• increase to + 最终数值
• increase by + 增加数值
• 原100 → 终300:是原3倍,增加了200%
• 增加300%:最终是原4倍
• 倍数计算:先定指标、基准和单位,再算总量
• 例外:不要把“翻倍”理解成增加两倍
| 结构 | 含义 | 例句 |
|---|---|---|
| increase by 50% | 在原值的基础上增加 50% | The number increased by 50%. |
| increase to 300 | 增加到 300 | The number increased to 300. |
| fall by 20% | 比原值减少了 20% | Sales fell by 20%. |

hundred 等的确数与概数
确数不加 s 不接 of,概数加 s 必接 of
• 确数:具体数词 + hundred/thousand/million/billion (不加 s,不接 of),如 two hundred students
• 概数:hundreds/thousands of (表示数以百/千计)
• 例外:具体数词 + hundred... + of + 限定范围 (如 the/these/my),如 two hundred of the students (表示“这批学生中的”)
• 区分:dozen、score 的确数与概数表达同理
| 确数 | 概数 |
|---|---|
| three hundred people | hundreds of people |
| two thousand trees | thousands of trees |
| five million users | millions of users |
| two dozen eggs | dozens of eggs |
| a score of players | scores of players |

In my 30s, I made painter friends and learned new ways of looking at art. However, I couldn’t let myself have a go at actually doing it. Though these new friends were abstract painters using oil paints, or were printmakers or sculptors, I took oil painting as the taboo (禁忌) high form I wasn’t allowed to practice.
句中“In my 30s”体现了年龄的表达。其结构为“in + 形容词性物主代词 + 基数词十位数复数形式”,用来表示处于某个年龄段(此处指30-39岁)。需注意 my 决定了此处指年龄而非 20 世纪 30 年代。全句意为:在我三十多岁时,我结交了画家朋友并学习了欣赏艺术的新方法,但我不敢尝试实际创作,将油画视为一种我不被允许实践的高深禁忌形式。
数词作修饰与时间长度
数词修饰单位名词:直接表示数量看数用单复数,连字符作修饰语用单数。
• 直接表示数量:单位按数量用单复数。
• 连字符构成修饰语:单位用单数(如 a one-hour meeting)。
• 表示“另外两天”:可用 another two days 或 two more days。
• one and a half 之后:可数单位名词用复数(如 one and a half hours),例外:也可说 an hour and a half。
| 结构 | 例句 | 含义 |
|---|---|---|
| 数词 + 复数单位 | two hours | 两小时 |
| 数词-单数单位 + 名词 | a two-hour meeting | 一次持续两小时的会议 |
| one and a half + 复数单位 | one and a half hours | 一个半小时 |
| another + 数词 + 复数单位 | another three days | 另外三天 |
| every + 数词 + 复数单位 | every four hours | 每四小时 |
| twice + 时间单位 | twice a week | 每周两次 |
| 表达 | 含义 | 例句 |
|---|---|---|
| another two days | 另外两天 | another two days |
| two more days | 另外两天 | two more days |
| two days longer | 多持续两天 | two days longer |
| a two-day trip | 持续两天的旅行 | a two-day trip |

这种药必须每四小时服用一次。 The school will hold a three-day sports meeting next week.
学校下周将举行为期三天的运动会。
•18 weekly one-hour pair meetings
句中“one-hour”体现了该知识点。它由“数词 + 名词”构成复合形容词,用连字符连接,修饰后面的名词 meetings。注意此时名词 hour 必须用单数形式,不能加 s。全句意为:18 次每周一次、每次一小时的搭档会面。

词性与修饰关系
形容词修饰名词/状态,副词修饰除名词外的成分。
• 形容词:修饰名词,或说明主语、宾语的性质状态。
• 副词:修饰动词、形容词、其他副词、整个句子或介词短语。
• 判定:看实际修饰谁、充当什么成分,而非仅看是否在动词前后。
| 句法功能 | 常见词性 | 例子 |
|---|---|---|
| 作定语 | 形容词 | a careful driver |
| 作表语 | 形容词 | The road is narrow. |
| 作宾语补足语 | 形容词 | Keep the room clean. |
| 作状语 | 副词 | drove slowly |
| 修饰形容词 | 副词 | extremely useful |

形容词、副词的位置与顺序
形容词与副词的位置有定式,顺序有先后。
• 多数形容词放名词前;修饰something/anything等复合不定代词或为形容词短语时后置。
• 多个前置形容词顺序:观点 → 大小 → 年龄 → 形状 → 颜色 → 来源 → 材料 → 用途。例外:受强调和习惯影响。
• 频率副词通常在实义动词前、be后或第一个助动词后。
• 方式副词常在动词宾语后,禁止插入动词与直接宾语之间。
| 结构 | 位置 | 例子 |
|---|---|---|
| 普通形容词定语 | 名词前 | a narrow road |
| 复合不定代词 + 形容词 | 复合不定代词后 | something important |
| enough 作定语 | 名词前或复合不定代词后 | enough time; something enough to eat |
| enough 作表语 | 形容词后 | old enough |
| -ing/-ed 分词短语作定语 | 名词后 | the man standing there |

她通常在家仔细阅读这些说明。 The boy standing near the window is my brother.
站在窗户旁边的男孩是我哥哥。
形容词变副词的拼写
形容词变副词的核心规则是加 -ly。
• 多数形容词:直接加 -ly
• 辅音字母 + y:y 变 i 再加 ly
• -le 结尾:去 e 加 y(如 simple → simply)
• -ic 结尾:加 -ally,例外:public → publicly
• 词尾 e:多数保留(如 safely),例外:true → truly
| 拼写变化 | 例词 |
|---|---|
| 直接加 ly | careful—carefully; quiet—quietly; safe—safely |
| y → ily | happy—happily; easy—easily; lucky—luckily |
| le → ly | simple—simply; possible—possibly; gentle—gently |
| ic → ically | basic—basically; scientific—scientifically |
| 特殊拼写 | true—truly; public—publicly; full—fully |
| 容易误拼的词 | 正确形式 | 说明 |
|---|---|---|
| true | truly | 去掉 e 再加 ly |
| public | publicly | 直接加 ly |

结果基本上与第一次实验的结果相同。 He is truly grateful for your help.
他真诚地感谢你的帮助。
同形词与 -ly 后意义变化
形容词与副词并非简单通过加 -ly 转换,需区分同形词与意义变化词。
• fast, hard, early, late 既是形容词也是副词,无需加 -ly。
• friendly, lovely, lonely, lively 是形容词;表示“友好地”用 in a friendly way。
• 部分词加 -ly 后意义改变,如 hardly 非 hard 的副词形式。
• good 是形容词,well 常作副词,也可作形容词表示身体健康。
| 原词 | 常见意义 | 带 ly 的词及意义 |
|---|---|---|
| hard | 努力地;猛烈地 | hardly:几乎不 |
| late | 晚;迟 | lately:最近 |
| near | 在附近;靠近 | nearly:几乎 |
| high | 高的;在高处 | highly:高度地;非常 |
| good | 好的 | well:好地;健康地 |
| 类别 | 常见词 |
|---|---|
| 形容词、副词同形 | fast, hard, early, late, straight, high |
| 通常只作形容词 | friendly, lovely, lonely, lively |
| 易混意义 | hard/hardly, late/lately, near/nearly |

她唱得很好,手术后身体也很好。 The staff were friendly to all the visitors.
工作人员对所有来访者都很友好。
系动词后用形容词
系动词连接主语和表语,表语常为形容词。
• 常用系动词:be, seem, become, remain。
• 感官系动词:look, sound, smell, taste, feel。
• 例外:同一动词表示实际动作时,用副词修饰。
• 扩展:形容词可作宾语补足语,说明宾语状态(如 keep the room clean)。
| 结构 | 例子 | 含义 |
|---|---|---|
| be/seem/become + 形容词 | The soup became cold. | 汤变凉了 |
| 感官动词 + 形容词 | The flowers smell sweet. | 花闻起来很香 |
| 感官动词 + 副词 | The cook tasted it carefully. | 厨师仔细地品尝它 |

长途旅行后,她看上去很疲惫。 Please keep the laboratory tidy during the experiment.
实验期间请保持实验室整洁。 The news made us happy.
这个消息使我们很高兴。
-ed 与 -ing 形容词
-ing 形容词表“性质”(使人产生某种感受),-ed 形容词表“状态”(感受者的心情)。
• -ing:说明事物具有使人产生某种感受的性质。
• -ed:说明人或其他有感受者所处的状态。
• 例外:a boring person(令人厌烦的人),an excited voice(表现出兴奋情绪的声音)。
• 常见成对词:interested/interesting, bored/boring, excited/exciting, disappointed/disappointing。
| 人的感受或状态 | 事物的性质 | 例句 |
|---|---|---|
| interested | interesting | an interested student; an interesting story |
| bored | boring | a bored student; a boring film |
| excited | exciting | an excited child; an exciting match |
| frightened | frightening | a frightened child; a frightening noise |
| tired | tiring | a tired worker; a tiring journey |
| disappointed | disappointing | a disappointed fan; a disappointing result |
| 形式 | 作定语时的常见意义 | 例子 |
|---|---|---|

她惊恐的表情表明那声音多么吓人。 There is a swimming pool and a broken window near it.
附近有一个游泳池和一扇破窗户。
比较级、最高级的规则变化
比较级/最高级:短词加 -er/-est,长词用 more/most。
• 单音节及部分双音节词:加 -er/-est
• 词尾为 e:加 -r/-st
• 重读闭音节(辅+元+辅):双写末字母再加词尾
• 辅音字母 + y:y 变 i 再加词尾

• 例外:部分双音节词两种形式均可
| 类型 | 原级—比较级—最高级 |
|---|---|
| 直接加词尾 | small—smaller—smallest; fast—faster—fastest |
| 词尾 e | large—larger—largest |
| 双写末字母 | big—bigger—biggest; hot—hotter—hottest |
| 辅音字母 + y | happy—happier—happiest; easy—easier—easiest |
| more / most | careful—more careful—most careful; slowly—more slowly—most slowly |
| 副词例外 | early—earlier—earliest; late—later—latest |

一个更小的房间更适合这项实验。 She works harder than any other member of the team.
她比团队里的其他任何成员都更努力。
Being new to the school made me even ____1____ , so it was surprising I’d ____2____ to anyone around me.
句中“even shyer”体现了该知识点。shyer 是形容词 shy 的比较级,遵循单音节形容词直接加 -er 的规则变化;而 even 在此作为程度副词,用于修饰比较级,表示“更加”。全句意思是:刚到新学校让我变得更加害羞,所以令人惊讶的是,我竟然能与周围的人交上朋友。
比较级、最高级的不规则变化
部分形容词和副词的比较级与最高级不遵循常规加-er/-est规则,需死记硬背。
• good/well → better → best
• bad/badly → worse → worst
• many/much → more → most
• little (数量少) → less → least;例外:体积小不适用
• farther:表实际距离

新图书馆比旧图书馆藏书更多,设施也更好。 His home is farther from school, but we need further information.
他家离学校更远,但我们需要进一步的信息。
同级比较与程度修饰
as...as 结构用原级,比较级前禁Very。
• as + 形容词/副词原级 + as:一样
• not as/so...as:不如
• 数量比较:as many + 复数名词 + as / as much + 不可数名词 + as
• 比较级修饰词:much, far, a lot, a little, a bit, even, still, rather
• 例外:very 修饰原级,或用于 the very best 等特定结构
| 结构 | 含义 | 例子 |
|---|---|---|
| as + 原级 + as | 与……一样 | as careful as you |

• 比较级 + and + 比较级 / more and more + 原级:越来越……
• the + 比较级 + of the two:两者中较……的那个
• 比较级表最高级(需排除自身):同范围用 than any other + 单数 / than all the other + 复数;例外:跨范围比较不加 other
| 句型 | 含义 | 例子 |
|---|---|---|
| 比较级 + than | 比……更 | clearer than the first one |
| the + 比较级 ..., the + 比较级 ... | 越……越…… | The more..., the fewer... |

• 结构:the + 最高级 + 名词 + in/of...
• 结构:one of the + 最高级 + 复数名词
• 排名:序数词 + 最高级(如 the second largest)
• 比较对象:必须同类同指标,用 that/those 或所有格替代(例:不能拿人口数与城市比)
• 程度最低:less...than 表示不如,the least 表示最低
| 结构 | 含义 | 例子 |
|---|---|---|
| the + 最高级 + 名词 + in/of | 某一范围内最…… | the best student in our class |

📌 北京真题 9 题原卷原题,答案按官方解析;单项填空 2 题;语法填空 7 空
After the long journey, the three of them went back home, .
A. hungry and tiredlyB. hungry and tiredC. hungrily and tiredlyD. hungrily and tired
看答案
✅ B. hungry and tired(形容词作主语补足语)
句子主干是 the three of them went back home,结构完整。空格处需填入成分描述主语的状态,此处应使用形容词作主语补足语,因此选择 hungry and tired。这类结构常用于描述人物在动作发生时的状态。最容易误选 C,因为很多学生习惯性认为修饰动词 went 必须用副词,但此处强调的是人的状态而非动作的方式。
Many people have donated that type of blood; however, the blood bank needs .
A. someB. lessC. muchD. more
看答案
✅ D. more(形容词比较级)
首先关注关键词 however,它表示转折,意味着前后句意相反。前半句说很多人捐了那种血,后半句则应表达血库仍然“不足”或“需要更多”。根据语境,more 表示“更多”,符合逻辑。A 选项 some 虽通顺但缺乏转折力度,B 选项 less 表示“更少”与 needs 矛盾,C 选项 much 通常不单独作宾语且无比较含义。最容易误选 A,因为它忽略了 however 带来的对比逻辑。

看答案
✅ meaningful(形容词)
与 healthy 并列修饰名词 experience,填形容词 meaningful。
Oliver says if you're (luck) enough to have someone close to you who enjoys cooking, ask them 3 you can join in when it's possible.

看答案

看答案
✅ worse(不规则比较级)
even 修饰比较级,bad 的不规则比较级为 worse。
Soon after moving to Switzerland, I 〔11〕(throw) a house-warming party and was greatly surprised when all 30 guests showed up (exact) on time.
看答案
✅ exactly(形容词变副词)

Maybe this morning you debated whether to get up or stay in bed slightly (long).
看答案
✅ longer(形容词比较级)
slightly 修饰比较级,表示“稍微更久”。
⚠️ 易错点
- 系动词说明主语状态时用形容词,The flowers smell sweet 不写 sweetly;实际嗅闻动作才可由副词修饰。
- friendly 通常是形容词,fast 和 hard 本身可作副词;不能见到副词就强行加 ly。
- hardly 表示几乎不,不能用它表达努力地;努力工作是 work hard。
- -ed/-ing 要按感受状态与引发感受的性质区分,不能机械记成人用 -ed、物用 -ing。
- 比较级不能同时叠加 more 和 -er,much easier 正确,more easier 和 very easier 错。

- 在同一范围比较须排除自身,班里最高者用 taller than any other student,不能漏 other。
- one of the best 后接复数名词,one of the best student 应改为 students。

📌 北京真题 17 题原卷原题,答案按官方解析;单项填空 9 题;语法填空 8 空
If you really have to leave during the meeting, you’d better leave the back door.
A. forB. byC. acrossD. out
看答案
✅ B. by(介词表示方式或途径)
句子主干是 you’d better leave,空格处需填入介词修饰离开的方式。by 在此处表示“通过……途径/方式”,by the back door 意为“经由后门(离开)”,符合语境。A 选项 for 表示方向,leave for 意为“出发去某地”,与后文不符;C 选项 across 表示横跨;D 选项 out 是副词,不能直接接名词。最容易误选 A,因为它忽略了 back door 是离开的通道而非目的地。
The wine industry in the area has developed in a special way, little foreign ownership.
A. byB. ofC. withD. from
看答案
✅ C. with(with 引导的伴随状语)
句子主干为 The wine industry has developed,空格处需填入介词引导的短语作伴随状语,描述行业发展时的状态。with 在此处表示“伴随/具有”,与 little foreign ownership 结合,意为“伴随着极少的外资所有权”。故选 with。容易误选 by,因为 by 通常表示手段或方式,而此处强调的是一种共存的状态而非达成发展的具体手段。
Would you mind not picking the flowers in the garden? They are everyone's enjoyment.
A. inB. atC. forD. to
看答案
✅ C. for(介词固定搭配)
首先分析句意,前句请求不要采花,后句解释原因,空格处需填入介词连接 enjoyment。这里考查 for enjoyment 这一固定表达,意为“为了寻求乐趣/为了欣赏”,表示目的。因此选 C。容易误选 A,因为 in 虽常与 enjoyment 连用(如 in enjoyment),但此处强调花朵存在的目的是给大众欣赏,而非处于某种状态。
With new technology, pictures of underwater valleys can be taken color.
A. byB. forC. withD. in
看答案
✅ D. in(介词固定搭配)
首先分析句子,主语是 pictures,谓语是 can be taken,空格处需要一个介词来修饰 color,表示照片的呈现方式。在英语中,表示“用某种颜色”或“彩色地”要用固定搭配 in color。因此选择 D。很多同学容易误选 A (by),因为习惯性认为 by 表示方式,但 by 通常接交通工具或手段,不能与 color 搭配表示色彩状态。
Do you think this shirt is too tight the shoulders?
A. atB. onC. toD. across
看答案
✅ D. across(介词辨析)
句子主干是 Do you think this shirt is too tight,关键在于 tight 与 shoulders 之间的空间关系。across 表示“横跨、在……整个宽度上”,此处指衬衫在肩膀这个区域横向太紧,符合语境。at 强调点,on 强调表面,to 表示方向,均不能体现衣服紧绷的横向跨度。最容易误选 A,因为 at 常接具体位置,但描述衣服尺寸紧绷时,across 是更地道的表达。
I have an appointment Dr. Smith, but I need to change it.
A. toB. offC. withD. from
看答案
✅ C. with(固定搭配 appointment with)
首先观察句子,关键词是 appointment(预约)和 Dr. Smith(人名)。在英语中,表示“与某人预约”要使用固定搭配 appointment with sb.,因此这里填 with 表示预约的对象。A 选项 to 虽然也可以接名词,但它通常表示方向或对象(如 go to the doctor),而不能与 appointment 搭配来表示“与某人预约”,故排除。
Jane is in a hurry because the train to the airport leaves half an hour.
A. byB. inC. forD. until
看答案
✅ B. in(表示时间的介词)
观察句子,because 引导原因状语从句,从句谓语 leaves 用一般现在时表示将来,关键词是 half an hour(半小时)。在表示“在一段时间之后”时,习惯用介词 in,故选 B。in half an hour 意为“半小时后”。很多同学容易误选 A,因为 by 意为“不迟于/在...之前”,强调截止时间,而此处表达的是距离出发的时间间隔。
Many people who live along the coast make a living fishing industry.
A. atB. inC. onD. by
看答案
✅ B. in(介词固定搭配)
首先分析句子结构,主语是 Many people,谓语是 make a living,意为“谋生”。此处需填入介词连接 fishing industry(渔业)。在英语中,表示在某个行业或领域中工作谋生,习惯用介词 in,即 make a living in...。因此选择 B。很多同学容易误选 D,因为 by 常接方式(如 by fishing),但此处宾语是 industry(行业),不能用 by。
—Good morning, Mr. Lee’s office.
—Good morning. I’d like to make an appointment next Wednesday afternoon.
A. forB. onC. inD. at
看答案
✅ A. for(介词 for 的用法)
首先看关键词 make an appointment(预约),后接具体时间。这里选 for 是因为 for 在此处表示“预定在……”,强调预约的目标时间点,make an appointment for + 时间是常用表达。很多同学容易误选 B (on),因为习惯性认为具体日期前用 on,但 on 侧重于动作发生的时刻,而 for 更能体现出“为了某个时间而预约”的预定含义。

When you see her walking towards you, you feel a deep sense of connection well up you.
看答案
✅ within / inside(表示内心涌现)
解析接受 within / inside;表示某种感受在某人内心涌现。
⚠️ 易错点
- at night 是泛指夜间,on a cold night 是具体夜晚;不要看到 night 就固定填 at。
- next Monday、this afternoon 前通常不用介词,不能机械写 on next Monday 或 in this afternoon。
- by Friday 是最迟星期五,until Friday 是持续到星期五;两者不能只按“到”字互换。
- 穿过森林通常用 through the forest,横穿街道用 across the street,不能只译成“穿过”就忽略路径。
- by bus 不加冠词,on the bus 有限定词;不能混写 by the bus 来表达一般乘车方式。
- 介词 to 后的动词要用 doing,如 look forward to meeting;不定式 to 后才接原形。
- 介词后人称代词用宾格:depend on him,不写 depend on he。
- 介词后的“是否”用 whether,如 depend on whether...;从句须用陈述语序。

- 用 see 的正确形式填空:We look forward to ______ you again.
看答案

- 用 he 的正确形式填空:The teacher sat beside ______ during the test.
看答案
✅ him beside 是介词,后面用人称代词宾格。
- 填 if 或 whether:They disagreed about ______ the museum should close on Mondays.
看答案
✅ whether about 后是表示是否的宾语从句,介词后用 whether。
二、动词
时态、语态、主谓一致、非谓语、情态、虚拟
07 动词时态先定时间参照点,再看动作状态。
📝 北京怎么考:北京卷语法填空常考谓语时态,旧卷单项填空也常考;阅读靠时态还原事件顺序,写作要求时间线一致。本章收录北京卷单项填空 34 题(2008—2018 年中的 11 年)、语法填空 16 空(2019—2026 年中的 8 年)。

• 现在时:主语为第三人称单数,普通实义动词通常加 -s/-es。
• 过去时:只要叙述时间属于过去即可使用,无需 yesterday。
• 否定/疑问:现在时用 do/does,过去时用 did,实义动词恢复原形。
• be 动词:不使用 do/does/did,按自身形式变化。

• 现在完成时:过去动作造成当前结果,或状态持续至今。
• 一般过去时:事件发生在已结束的过去时间。
• 现在完成时禁配:yesterday, in 2020, two days ago 等明确结束的时间状语。
• today, this week:视作仍在继续则用完成时。
• have been to:去过且已返回。
• have gone to:已去且未返回。
| 比较项目 | 一般过去时 | 现在完成时 |
|---|---|---|
| 参照点 | 过去 | 现在 |

她的手脏了,因为她刚才一直在种花。
过去完成时的参照点
过去完成时 = 过去的过去(动作发生在某个过去点之前,或状态持续到该点)。
• 判断标准:能明确指出“过去点”和“更早动作”。
• 误区:不等于“很久以前”。
• 例外:before、after 已交代先后时,可用一般过去时。
• 特殊用法:had hoped/planned 表示原先愿望或打算未实现。
| 时间线索 | 时态处理 | 例句 |
|---|---|---|
| by the time + 过去事件 | 主句用过去完成时 | By the time he arrived, we had finished the work. |
| before + 过去事件 | 较早动作常用过��完成时 | Before he joined the team, he had trained for two years. |

时态呼应与解题顺序
主句定基调,从句按时间线呼应。
• 主句过去时 → 同时发生:用过去时
• 主句过去时 → 更早发生:用过去完成时
• 主句过去时 → 后来发生:用过去将来时
• 例外:客观真理或仍然有效的事实,保留现在时
• 语法填空步骤:判断是否缺谓语 → 找全文及局部时间线 → 检查主谓一致与语态
| 主句叙述时间 | 从句与主句动作的关系 | 从句常用形式 | 例句 |
|---|---|---|---|
| 现在 | 从句表示将来 | will do | I know that he will come. |
| 过去 | 与主句动作同时发生 | 一般过去时 | She said that she was busy. |
| 过去 | 早于主句动作发生 | 过去完成时 | She said that she had finished it. |
| 过去 | 晚于主句动作发生 | 过去将来时 | She said that she would call me. |
| 过去 | 表达客观真理或长期规律 | 一般现在时 | He explained that the earth revolves around the sun. |

各时态标志词速查
• 标志词作用:时间状语和标志词只提供时态线索,不能脱离语境机械决定答案。
• 双重判断:一个短语可能同时提供时间指向和动作状态,需要结合谓语结构一起判断。
• 参照转换:for、since 等词可以提示持续关系,但完成时还是过去完成时取决于参照点。
• 过去将来:the following day、two years later 等词只有放在过去语境中才表示过去将来。
• 信号冲突:多个时间信号不一致时,应以句子的叙述时间和逻辑关系为准。
| 时态 | 常见标志词或时间状语 | 语境提示 |
|---|---|---|
| 一般现在时 | always、usually、often、sometimes、every day、on Mondays、twice a week | 习惯、事实、状态或按规定发生的事 |
| 一般过去时 | yesterday、last night、last week、in 2020、two days ago、the other day | 已经结束的过去事件或过去习惯 |
| 一般将来时 | tomorrow、next week、next year、in three years、soon | 说话人所说的将来 |
| 过去将来时 | the following day、the next week、two years later、the next month | 以过去为参照点的将来 |
| 现在进行时 | now、at present、currently、these days、Look!、Listen! | 此刻正在进行、近期反复或暂时状态 |
| 过去进行时 | at that time、at that moment、then、while、when + 过去事件、all morning | 过去某时正在进行 |
| 将来进行时 | this time tomorrow、this time next week、at nine tomorrow | 将来某一时刻正在进行 |
| 现在完成时 | already、just、yet、ever、never、so far、recently、since、for、up to now | 过去与现在有关或状态持续至今 |
| 过去完成时 | by + 过去时间点、by the time + 过去事件、before + 过去事件、already by then | 早于某个过去参照点 |
| 现在完成进行时 | for、since、how long、all morning、recently、lately | 活动持续到现在并强调过程 |
| 容易误导的信号 | 可能表示的时间 | 进一步判断 |
|---|---|---|
| now | 现在进行时或一般现在时 | 看谓语表示正在进行的动作还是存在的状态 |
| this morning / this week | 一般过去时或现在完成时 | 该时间段已经结束还是仍在继续 |
| in two weeks / in 2020 | 前者常指将来,后者常指过去 | 以说话时间为中心判断 |

• 搭配作用:正确的时间状语搭配和固定动词搭配能够帮助判断时态、语态和动作状态。
• in 的用法:in two weeks 表示从现在起过两周,in 2020 表示在过去某年。
• on 和 at:on 后接具体日期或某天的名称,at 后接钟点或具体时刻。
• by 的用法:by + 时间点表示截至该时间已经完成某事。
• for 和 since:for 接持续的长度,since 接持续的起点。
• 固定搭配:have been to、have gone to、be about to do、be used to doing 等结构具有固定意义。
• 形式限制:take place 通常不用进行时,to 在 be used to 和 look forward to 中是介词,后接 doing。

时态、语态与情态动词的配合
• 区分维度:时态说明动作发生的时间和状态,语态说明动作的承受者,情态动词说明能力、义务、可能或意愿。
• 情态结构:can、must、should、may、might、will、would、need 等情态动词后接动词原形,不带 to,也不随主语变化。
• 完成式情态:can、could、must、may、might、should 等后可接 have 加过去分词,表示对过去的推测或能力。
• 被动结构:被动语态由 be 加动词过去分词构成,其中 be 承担时态和数的变化。
• 时态位置:被动句的时态主要通过 am/is/are、was/were、will be、has been、had been 等形式体现。
• 主动被动一致:主动句和被动句通常使用相同的时态,不能只根据动词是-ed 形式就判断为被动。
• 过去推测:must have done 表示对过去情况的肯定推测,不能等同于现在时的 must do。
| 结构 | 构成 | 表达功能 | 例句 |
|---|---|---|---|
| 情态动词 + 动词原形 | can / must / should / may + do | 能力、义务、可能或意愿 | He can solve the problem. |
| 情态动词 + have done | can / could / must / may + have done | 对过去的推测或能力 | She must have left earlier. |
| 现在被动 | am / is / are + 过去分词 | 现在或一般事实 | The results are being checked. |
| 过去被动 | was / were + 过去分词 | 过去发生的被动动作 | The old bridge was built in 1890. |
| 将来被动 | will be + 过去分词 | 将来发生的被动动作 | The results will be announced tomorrow. |
| 现在完成被动 | have / has been + 过去分词 | 被动动作对现在的影响 | The work has been completed. |
| 过去完成被动 | had been + 过去分词 | 过去参照点之前已经完成 | The room had been cleaned before we arrived. |
他十分钟就能解出这道题。 The results have been announced.
结果已经公布了。 The old bridge was built in 1890.
那座旧桥建于1890年。 She must have left earlier.
她Earlier一定已经离开了。
时态易混辨析
• 过去与完成:一般过去时关注过去事件本身,现在完成时关注过去动作与现在的联系。
• 短动作与背景:过去一般时通常表示较短的完成动作,过去进行时通常表示较长的背景过程。
• 结果与过程:现在完成时强调结果或数量,现在完成进行时强调持续过程或反复活动。
• 两个过去动作:只有需要明确较早动作已经完成时,才使用过去完成时,否则两个一般过去时即可。
• 将来表达:will、be going to、现在进行时和一般现在时分别对应临时决定或预测、已有打算、具体安排和时刻表。
• 最终依据:判断时态时应综合时间状语、上下文、动作关系和谓语结构,不能只进行中文对译。
| 易混时态 | 关键区别 | 典型例句 |
|---|---|---|
| 一般过去时 / 现在完成时 | 过去事件本身 / 过去与现在的联系 | I lost my key yesterday. / I have lost my key. |
| 一般过去时 / 过去进行时 | 较短且完成的动作 / 较长且作为背景的动作 | She came in. / She was coming home. |
| 现在完成时 / 现在完成进行时 | 结果、状态或数量 / 持续过程或反复活动 | He has written the report. / He has been writing the report. |
| 一般过去时 / 过去完成时 | 普通过去动作 / 明确早于另一个过去参照点 | He called me after he arrived. / He had called me before he arrived. |
| will do / be going to do | 临时决定或一般预测 / 事先打算或依据迹象预测 | I will help you. / I am going to help you. |
| be going to do / 现在进行时 | 计划、打算或迹象 / 已安排好的具体活动 | I am going to study abroad. / I am meeting her tomorrow. |

📌 北京真题 50 题原卷原题,答案按官方解析;单项填空 34 题;语法填空 16 空
—Have you read book called Waiting for Anya?
—Who it?
A. writesB. has writtenC. wroteD. had written
看答案
✅ C. wrote(一般过去时)
对话中提到一本已出版的书,询问作者是谁。写书这个动作发生在过去且已经完成,是一个具体的历史事实,因此应使用一般过去时 wrote。虽然书的内容现在依然存在,但“创作”这一行为是过去发生的。最容易误选 B,因为虽然现在完成时强调对现在的影响,但在询问具体作者身份时,习惯上将其视为过去发生的单一事件,而非持续到现在的状态。
The hotel wasn’t particularly good. But I in many worse hotels.
A. was stayingB. stayedC. would stayD. had stayed
看答案
✅ D. had stayed(过去完成时)
首先分析时态,前句 wasn’t 为一般过去时,交代了入住酒店时的状态。后句表达的是在入住这家酒店“之前”就已经经历过很多更差的酒店,属于“过去的过去”,因此必须使用过去完成时 had stayed。选项 B stayed 为一般过去时,无法体现出动作发生的先后顺序,是学生最容易误选的干扰项。
No decision about any future appointment until all the candidates have been interviewed.
A. will be madeB. is madeC. is being madeD. has been made
看答案
✅ A. will be made(主将从现)
观察句子结构,until 引导的是时间状语从句,从句谓语 have been interviewed 使用了现在完成时。根据“主将从现”原则,主句应使用一般将来时。且 decision 与 make 构成被动关系,故选 will be made。最容易误选的 B 选项 is made 是一个一般现在时,无法与 until 引导的未来时间逻辑相匹配。
Scientists have many theories about how the universe into being.
A. cameB. was comingC. had comeD. would come
看答案
✅ A. came(一般过去时)
句子主干是 Scientists have many theories,宾语从句探讨的是宇宙产生的方式。宇宙的诞生是一个发生在远古时期的既定事实,因此从句应使用一般过去时,选择 came。come into being 是固定搭配,意为“产生、出现”。很多同学容易误选 C,认为主句是现在时,从句必须用过去完成时,但此处并非强调“过去的过去”,而仅是陈述历史事实。
When I talked with my grandma on the phone, she sounded weak, but by the time we up, her voice had been full of life.
A. were hangingB. had hungC. hungD. would hang
看答案
✅ C. hung(by the time 引导的时态)
首先观察关键词 by the time 和主句的时态 had been。by the time 引导的时间状语从句表示“到……时候为止”,其从句时态通常与主句形成递进关系。主句使用了过去完成时,说明动作发生在过去,因此从句应使用一般过去时,故选 hung。最容易误选 B,因为很多学生习惯性认为 by the time 必须搭配完成时,但实际上完成时应体现在主句中,而非从句中。
John was given the same suitcase his father and grandfather with them to school.
A. tookB. had takenC. were takingD. would take
看答案
✅ B. had taken(过去完成时)
首先分析结构,the same suitcase 后省略了关系代词 that,引导定语从句修饰 suitcase。主句谓语 was given 是过去时,而父亲和祖父带行李去学校的行为发生在“被赠送”之前,属于“过去的过去”,因此必须使用过去完成时 had taken。A 选项 took 仅表示过去,无法体现动作的先后顺序,是学生最容易误选的干扰项。
--I'm not finished with my dinner yet.
--But our friends for us.
A. will waitB. waitC. have waitedD. are waiting
看答案
✅ D. are waiting(现在进行时)
首先看对话语境,第一句“I'm not finished... yet”表明说话人此时还没吃完饭。第二句用 But 引导转折,意在催促对方,暗示朋友们此时此刻正在等待。因此,应使用 are waiting 表示动作正在进行。A 选项 will wait 表示将要发生,不符合此时此刻催促的紧迫感,故排除。
--I'm sorry, but I don't quite follow you. Did you say you wanted to return on September 20?
--Sorry, I myself clear. We want to return on October 20.
A. hadn't madeB. wouldn't makeC. don't makeD. haven't made
看答案
✅ D. haven't made(现在完成时)
分析对话语境,对方表示没听懂,说话人意识到之前的表达导致了现在的误解。这里强调的是“到目前为止没说清楚”这一状态对现在产生的影响,因此使用现在完成时 haven't made。选项 A 过去完成时需有明确的过去时间点;B 属于情态动词 would 的否定形式,不合逻辑;C 一般现在时无法体现动作对现在的影响。最容易误选 A,但此处并非“过去的过去”,无需使用过去完成时。
It took me a long time before I was able to fully appreciate what they for me.
A. had doneB. didC. would doD. were doing
看答案
✅ A. had done(过去完成时)
观察句子结构,主句谓语 was able to 为过去时,表示在过去某个时间点才意识到某事。而“他们为我做的事”在逻辑上发生在“意识到”之前,使用过去完成时 had done 可以清晰地标示出动作的先后顺序。B 选项 did 在语法上同样正确,但在高考单项选择题的语境下,当考点旨在考察“过去的过去”这一逻辑关系时,had done 是更符合出题意图的精准选项。C 和 D 时态与语境不符。
Tom in the library every night over the last three months.
A. worksB. workedC. have been workingD. had been working
看答案
✅ C. have been working(现在完成进行时)
观察时间状语 over the last three months,表示从过去持续到现在的时间段,是典型的现在完成时或现在完成进行时的标志。句中强调动作的持续性,故选 have been working。注意主语 Tom 为第三人称单数,此处 have 应为 has,原题选项 C 存在印刷错误,但逻辑上考查的是现在完成进行时。B 选项 worked 表示过去某个时间点,与持续性状语不符。
—That must have been a long trip.
—Yeah, it us a whole week to get there.
A. takesB. has takenC. tookD. was taking
看答案
✅ C. took(一般过去时)
首先观察对话上下文,第一句中的 must have been 是对过去情况的肯定推测,明确了整个对话发生的背景是过去。第二句是在具体描述这次旅行花费的时间,属于过去发生的既定事实,因此动词应使用一般过去时,选择 took。最容易误选的是 B,因为看到 a whole week 容易联想到现在完成时,但此处强调的是过去的一次具体经历,而非持续到现在的状态。
—Bob has gone to California.
—Oh, can you tell me when he ?
A. has leftB. leftC. is leavingD. would leave
看答案
✅ B. left(一般过去时)
首先看前文 Bob has gone to California,可知 Bob 已经离开,这是一个既定事实。问句询问的是他离开的具体时间点,而“离开”这个动作发生在过去,因此应使用一般过去时 left。注意 when 引导的宾语从句中,询问过去发生的具体时间时不能用现在完成时,故 A 选项 has left 错误。
By the time you have finished this book, your meal cold.
A. getsB. has gotC. will getD. is getting
看答案
✅ C. will get(主将从现(完成时))
观察关键词 By the time,它引导时间状语从句。从句使用了现在完成时 have finished,表示在未来某个时间点之前动作已完成,此时主句应使用一般将来时来描述届时的状态,因此选择 will get。最容易误选 B,因为考生常机械地将 by the time 与完成时挂钩,而忽略了主句是对未来结果的预测。
George said that he would come to school to see me the next day, but he .
A. wouldn’tB. didn’tC. hasn’tD. hadn’t
看答案
✅ B. didn’t(时态一致与省略)
首先观察句子结构,前半句用 said 引导宾语从句,交代了过去的一个约定。后半句由 but 连接,表示实际发生的情况与约定相反。这里发生了省略,完整表达应为 but he didn't come to school,因此应选 didn't 来与前半句的过去时态保持一致。最容易误选 A,因为看到 would 习惯性想选 wouldn't,但 wouldn't 表示“意愿”或“过去将来”,而此处强调的是事实结果,必须用一般过去时。
Our friendship quickly over the weeks that followed.
A. had developedB. was developingC. would developD. developed
看答案
✅ D. developed(一般过去时)
观察时间状语 over the weeks that followed,其中 followed 是定语从句中的谓语动词,明确了整个语境发生在过去。句子描述的是过去一段时间内发生的客观事实,无需强调动作的持续或完成,因此直接使用一般过去时 developed。B 选项进行时强调动作正在进行,C 选项将来时与过去语境冲突,最容易误选 A,因为 had developed 表示过去完成时,需有另一个过去的时间点作为参照,而此处仅是简单的过去叙述。
—Do you think Mom and Dad late?
—No, Swiss Air is usually on time.
A. wereB. will beC. would beD. have been
看答案
✅ B. will be(一般将来时)
首先观察对话语境,问句在询问父母是否会迟到,答句提到航空公司“通常准时”,说明讨论的是尚未发生的未来情况。因此应选用 will be 表示对未来的预测。A 选项 were 是过去时,与语境不符;C 选项 would be 通常用于虚拟语气或过去将来时,此处无触发条件;D 选项 have been 是现在完成时,强调对现在的影响,不符合询问预测的逻辑。最容易误选 A,因为它忽略了对话中关于航班准时性的预测语境。
Hurry up! Mark and Carl us.
A. expectB. are expectingC. have expectedD. will expect
看答案
✅ B. are expecting(现在进行时表此时此刻)
观察句首的“Hurry up!”,该祈使句营造了紧迫的语境,暗示动作发生在此时此刻。在这种即时场景下,使用现在进行时 are expecting 最能体现“他们现在正等着我们”的动态感。A项 expect 侧重于客观事实或心理状态,缺乏紧迫感;C项 have expected 强调期待的状态已持续一段时间;D项 will expect 表示将来才会期待。相比之下,B项最符合当下的语境逻辑。
—So what is the procedure?
—All the applicants before a final decision is made by the authority.
A. interviewB. are interviewingC. are interviewedD. are being interviewed
看答案
✅ C. are interviewed(一般现在时被动语态)
分析句子结构,主语 applicants(申请人)与动词 interview(面试)之间是被动关系。根据语境,对话在讨论 procedure(程序),描述的是一个常规流程,应使用一般现在时的被动语态,故选 are interviewed。A 项和 B 项均为主动语态,申请人不能主动面试,故排除;D 项 are being interviewed 强调动作正在进行,不符合描述通用程序的语境。
---Hi, let’s go skating.
--- Sorry, I’m busy right now. I in an application form for a new job.
A. fillB. have filledC. am fillingD. will fill
看答案
✅ C. am filling(现在进行时)
首先看上下文,对方邀请去滑冰,说话人回答“Sorry, I’m busy right now”,其中的 right now 是关键时间状语,表明动作正在发生。因此应选 am filling,表示此时此刻正在填写申请表。A 选项 fill 是一般现在时,表示习惯或事实,不符合语境;B 选项 have filled 是现在完成时,表示动作已完成,与 busy 矛盾。
--- What time is it?
--- I have no idea. But just a minute, I it for you.
A. checkB. checkedC. will checkD. would check
看答案
✅ C. will check(一般将来时)
观察对话语境,对方询问时间,说话人回答“just a minute(等一下)”,表明“查询时间”这个动作将在说话之后立即发生。因此应使用一般将来时 will check 来表示此时此刻做出的决定或承诺。最容易误选 A,虽然 check 在语法上可作谓语,但一般现在时表示习惯或客观事实,不符合此处“马上要做”的语境。
I found the lecture hard to follow because it when I arrived.
A. startedB. was startingC. would startD. had started
看答案
✅ D. had started(过去完成时)
首先观察时间状语从句 arrived 是过去式,主句 found 也是过去式,说明整件事发生在过去。根据逻辑,我到达(arrived)的时候,讲座已经开始了,所以“开始”这个动作发生在“到达”之前,即“过去的过去”,必须用过去完成时 had started。最容易误选 A,因为 started 表示两个动作同时发生或先后顺序不明显,无法体现出“我已经迟到了”这一隐含逻辑。
In the last few years, China great achievements in environmental protection.
A. has madeB. had madeC. was makingD. is making
看答案
✅ A. has made(现在完成时)
首先观察时间状语 in the last few years,该短语表示“在最近的几年里”,强调从过去持续到现在的时间段。根据时态逻辑,此时应使用现在完成时,故选 A. has made。注意区分 in the last few years 与 in the past few years,两者均指向现在完成时。最容易误选的 B. had made 是过去完成时,必须有明确的“过去的过去”作为参照点,而本句中没有。
—Did you have difficulty finding Ann’s house?
—Not really. She us clear directions and we were able to find it easily.
A. was to giveB. had givenC. was givingD. would give
看答案
✅ B. had given(过去完成时)
首先看对话背景,问句用 Did 引导,答句用 were able to,确定整体时间线在过去。Ann 给方向这个动作发生在“找到房子”之前,属于“过去的过去”,因此必须使用过去完成时 had given。A 项 be to do 表示计划或命令,C 项过去进行时强调过程,D 项 would give 表示过去将来时,均不符合逻辑。最容易误选 C,但此处强调的是结果而非动作正在进行。
—Dr. Jackson is not in his office at the moment.
—All right. I him later.
A. will callB. have calledC. callD. will be calling
看答案
✅ A. will call(一般将来时)
首先观察对话语境,第一句交代杰克逊博士目前不在办公室,第二句中的 later 是关键时间状语,表明动作发生在将来。根据语境,说话人在得知对方不在后,临时决定稍后打电话,这种“临时决定”应使用一般将来时,故选 will call。D 选项 will be calling 强调动作的持续或计划,不符合此处简单的意愿表达。
Jack in the lab when the power cut occurred.
A. worksB. has workedC. was workingD. would work
看答案
✅ C. was working(过去进行时)
首先观察关键词 occurred,可知整句背景发生在过去。句子由 when 引导的时间状语从句连接,表示一个动作在另一个动作发生时正在进行。因此,应使用过去进行时 was working 来描述断电瞬间杰克的状态。注意 A 选项 works 是现在时,B 选项 has worked 是现在完成时,均与过去的时间基调不符,故排除。
—Excuse me,which movie are you waiting for?
—The new Star Wars.We here for more than two hours.
A. waitedB. waitC. would be waitingD. have been waiting
看答案
✅ D. have been waiting(现在完成进行时)
首先关注时间状语 for more than two hours,这表明动作从过去开始一直持续到现在。对话背景是两人正在排队,等待这个动作仍在进行且强调过程,因此应选 have been waiting。A 选项 waited 是一般过去时,表示动作已结束,与语境不符。
I half of the English novel,and I’ll try to finish it at the weekend.
A. readB. have readC. am readingD. will read
看答案
✅ B. have read(现在完成时)
首先观察句子结构,后半句用 will try 表示将来的计划,前后存在时间上的承接关系。前半句强调到目前为止已经完成的进度(看了一半),这种“过去发生且对现在产生影响”的情况应使用现在完成时,故选 have read。最容易误选 A,因为 read 的原形和过去式拼写相同,但此处强调的是状态的累积而非简单的过去事实,且与后文的将来时衔接,用完成时更自然。
— that company to see how they think of our product yesterday?
—Yes. They are happy with it.
A. Did you callB. Have you calledC. Will you callD. Were you calling
看答案
✅ A. Did you call(一般过去时)
首先观察句末的时间状语 yesterday,这明确提示动作发生在过去。根据时态一致性,应选择一般过去时,故选 Did you call。该句是对过去某个具体时间点发生的动作进行询问。最容易误选的是 B,因为很多学生习惯性地在询问“是否做过某事”时使用现在完成时,但现在完成时不能与具体的过去时间状语(如 yesterday)连用。
In the 1950s in the USA, most families had just one phone at home, and wireless phones yet.
A. haven’t inventedB. haven’t been inventedC. hadn’t inventedD. hadn’t been invented
看答案
✅ D. hadn’t been invented(过去完成时的被动语态)
时间是 In the 1950s,说的是“到 1950 年代那时为止,无线电话还没有被发明出来”。“截至过去某个时候还没发生”用过去完成时;电话是“被发明”的,用被动,合起来就是 hadn’t been invented,故选 D。yet 用在否定句里表示“还(没有)”,常和完成时连用。B. haven’t been invented 是现在完成时,参照点是现在,和 1950 年代的背景矛盾;A、C 是主动,电话不会自己发明。
Peoplebetter access to health care than they used to, and they’re living longer as a result.
A. will haveB. haveC. hadD. had had
看答案
✅ B. have(一般现在时)
首先观察句子结构,本句由 and 连接两个分句,后半句 they’re living longer 为现在进行时,表示当前的状态。前半句通过 than they used to 进行对比,强调的是人们目前拥有的医疗条件,因此应填入一般现在时 have。最容易误选 C,因为看到 used to 容易被误导认为全句在讲过去,但实际上对比的重心在现在。
—Hi, I’m Peter. Are you new here? I haven’t seen you around?
—Hello, Peter. I’m Bob. I just on Monday.
A. startB. have startedC. startedD. had started
看答案
✅ C. started(一般过去时)
观察句子,关键词是 on Monday,这是一个明确的过去时间状语,表示动作发生在过去的某个具体时间点。根据时态一致性原则,此处应使用一般过去时,因此选择 started。注意 just 在这里仅表示“刚刚”,并不代表必须使用现在完成时。最容易误选的 B 选项 have started 是现在完成时,它不能与具体的过去时间状语(如 on Monday)连用。
Susan had quit her well-paid job and as a volunteer in the neighborhood when I visited her last year.
A. is workingB. was workingC. has workedD. had worked
看答案
✅ B. was working(过去进行时)
首先关注时间状语 when I visited her last year,确定整个语境发生在过去。句子描述的是在“我访问她”这个过去的时间点,Susan 处于一种持续的状态,即当时正在作为志愿者工作,因此应使用过去进行时 was working。最容易误选的是 D 选项 had worked,虽然前面有 had quit,但此处强调的是访问时的状态而非动作的先后顺序,故不选过去完成时。
China’s high-speed railways from 9,000 to 25,000 kilometers in the past few years.
A. are growingB. have grownC. will growD. had grown
看答案
✅ B. have grown(现在完成时)
首先观察句末的时间状语 in the past few years(在过去几年里),这是一个典型的标志词,表示动作从过去持续到现在。因此应选用现在完成时 have grown 来描述高铁里程的增长情况。A 选项 are growing 表示现在进行时,强调此时此刻正在发生,不符合时间状语;C 选项 will grow 表示将来时,逻辑不通。最容易误选的是 D 选项 had grown,它表示过去完成时,必须有另一个过去的时间点作为参照,而本句中没有。
A rescue worker risked his life saving two tourists who in the mountains for two days.
A. are trappingB. have been trappedC. were trappingD. had been trapped
看答案
✅ D. had been trapped(过去完成时的被动语态)
句子主句谓语 risked 为一般过去时,who 引导的定语从句描述的是游客被困的状态,发生在救援之前,且持续了两天,符合“过去的过去”且具有持续性,故选 had been trapped。此处 trap 为及物动词,游客是被困住,需用被动语态。B 选项 have been trapped 是现在完成时,与主句的时态不一致,无法构成逻辑上的先后顺序。

08 被动语态主语承受动作,时态变化落在助动词上。
📝 北京怎么考:北京卷语法填空常把语态、时态、主谓一致合在一个动词空中考查;旧卷单项填空也考查不同时间背景下的被动形式。本章收录北京卷单项填空 7 题(2009—2016 年中的 7 年)、语法填空 4 空(2020—2026 年中的 4 年)。
主动被动的判断
主语发出动作用主动,主语承受动作用被动。
• 形式:be + 过去分词(be随主语和时态变)。
• 转换:原宾语变主语;原主语用by引出,不重要或未知时省略。
• 判断:不看中文是否有“被”,看英语主语与动词的关系。
| 对比项 | 主动语态 | 被动语态 |
|---|---|---|
| 主语角色 | 动作发出者 | 动作承受者 |
| 基本谓语 | 动词原形或变化形式 + 宾语 | be + 过去分词 |
| 动作发出者 | 通常在句中作主语 | 可由 by 引出,也可省略 |
| 例句 | The volunteers cleaned the beach. | The beach was cleaned by the volunteers. |
志愿者清理了海滩。 The beach was cleaned by the volunteers.
海滩由志愿者清理了。 The package was delivered this morning.
包裹今天上午被送到了。 The classroom is being cleaned by the students.
学生们正在打扫教室。
被动谓语构成表
被动语态 = be 动词(随时态变化)+ 过去分词 (done)
• 先定时间时态,再加 be + done
• 进行被动:be being done
• 完成被动:have/has been done
• being 与 been 不可互换
• 例外:将来进行和完成进行的被动形式很少使用,常规表达直接改写
| 时态或结构 | 被动构成 | 使用说明 |
|---|---|---|
| 一般现在时 | am/is/are + 过去分词 | 主语单数用 is,复数用 are |
| 现在进行时 | am/is/are being + 过去分词 | 表示动作正在进行 |
| 一般过去时 | was/were + 过去分词 | 表示过去发生的动作 |
| 过去进行时 | was/were being + 过去分词 | 表示过去某时正在进行的动作 |
| 一般将来时 | will be + 过去分词;am/is/are going to be + 过去分词 | 表示将来要发生的被动动作 |
| 过去将来时 | would be + 过去分词;was/were going to be + 过去分词 | 常用于转述过去内容或条件句 |
| 现在完成时 | have/has been + 过去分词 | 强调过去动作对现在的影响或持续关系 |
| 过去完成时 | had been + 过去分词 | 表示过去某一时间前已经完成 |
| 将来完成时 | will have been + 过去分词 | 表示到将来某时已经完成 |
| 现在完成进行时 | have/has been being + 过去分词 | 极少用于被动,常规表达优先改写 |
| 过去完成进行时 | had been being + 过去分词 | 极少用于被动,常规表达优先改写 |
| 将来进行时 | will be being + 过去分词 | 极少用于被动,常规表达优先改写 |
| 情态动词 | can/must/should 等 + be + 过去分词 | 情态动词后不加 to |
| 主动结构 | 被动结构 | 例子 |
|---|---|---|
| can do | can be done | It can be finished by us. |
| must do | must be done | It must be checked. |
| should do | should be done | It should be repaired. |
| used to do | used to be done | It used to be sold here. |
| 句型 | 被动语序 | 例子 |
|---|---|---|
| 否定句 | 主语 + 第一个助动词 + not + 其余部分 | It has not been done. |
| 一般疑问句 | 第一个助动词 + 主语 + 其余部分 + ? | Has it been done? |

这项工作将在下周完成。 The room must be cleaned before the meeting.
会议室必须在开会前打扫干净。 Has the letter been sent?
这封信已经寄出去了吗?
时态语态一致联查
动词填空必查:时态 → 语态 → 主谓一致
• 查时间:确定事件发生何时
• 查语态:主语是动作发出者还是承受者
• 查单复:主语是单数还是复数
• 例外:主将从现适用于被动,从句可用 is/are done
• 否定:not 放在第一个助动词后
• 疑问:第一个助动词提到主语前
| 检查层面 | 关键问题 | 常见被动结果 |
|---|---|---|
| 时间 | 动作发生在什么时候? | is done / was done / will be done |
| 语态 | 主语是否承受动作? | be + 过去分词 |
| 主谓一致 | 主语是单数还是复数? | is done / are done |
| 时态呼应 | 从句是否表示将来? | 主将从现:is/are done |
| 过去动作先后 | 两个过去动作哪个先发生? | 先发生的动作常用 had been done |

不能直接用被动的动词
不及物动词和系动词不能用被动语态。
• 不及物动词(如happen, occur, arrive, disappear, die, rise, appear)不用被动。
• 系动词(如seem, become, look, sound, taste)表示状态或感受时不用被动。
• 例外:带介词的动词短语(如look after)整体带宾语,可以用被动。

|---|---|---|---|
| 不及物动词 | The accident happened. | 不能 | happen 后面不能直接接宾语 |
| 不及物动词 | The price rose sharply. | 不能 | rise 表示自行上升 |
| 系动词 | The soup tastes delicious. | 不能 | taste 连接主语和表语 |

事故发生在大门附近。 The soup tastes delicious.
这汤尝起来很鲜美。 The injured bird is being looked after carefully.
那只受伤的鸟正受到细心照料。 The price rose sharply last year.

主动形式表达被动意义
部分结构语义是被动,但习惯用主动形式。
• sell/wash/write 等 + well/easily 等:描述事物性能
• need/want/require doing = need/want/require to be done:表示“需要被……”
• be worth doing:值得被……
• 主语 + be + easy/hard 等 + to do:主语是不定式的逻辑宾语
• 例外:不能把所有被动句都改成主动
| 结构 | 例子 | 被动意义 |
|---|---|---|
| 主语 + 副词 + 动词 | This pen writes smoothly. | 这支笔好写 |
| need/want/require + doing | The floor needs cleaning. | 地板需要打扫 |
| be worth + doing | The plan is worth considering. | 这个计划值得考虑 |
| 形容词 + to do | The question is easy to answer. | 这个问题容易回答 |
这些衬衫很耐洗,但在我们店里它们是手洗的。 The floor needs cleaning.
地板需要打扫。 The plan is worth considering.
这个计划值得考虑。 The question is easy to answer.
这个问题很容易回答。
双宾语与短语被动
双宾语动词可任选一宾语作主语,短语被动需保留介词或副词。
• 人作主语:直接变被动。
• 物作主语:补出搭配介词(如 give sth to sb, buy sth for sb)。
• 短语被动:保留必要介词/副词(如 be laughed at, be taken care of)。
• 例外:并非所有双宾语动词都能两种转换,需遵循实际搭配。
| 主动结构 | 被动转换 | 说明 |
|---|---|---|
| give sb sth | sb was given sth / sth was given to sb | 两种语序表达不同角度 |
| send sb sth | sb was sent sth / sth was sent to sb | 两种语序表达不同角度 |
| tell sb sth | sb was told sth / sth was told to sb | 两种语序表达不同角度 |
| buy sb sth | sb was bought sth / sth was bought for sb | 注意 for 不能省略 |
| show sb sth | sb was shown sth / sth was shown to sb | 两种语序表达不同角度 |

感官使役动词的被动
感官动词和 make 的被动语态,原省略的 to 必须补回。
• do 变 be made/seen/heard to do
• doing 仍保留 doing(表示正在发生)
• 例外:let 改用 be allowed to do

工人们被允许提前离开。 He had his bicycle repaired.

get done 与状态辨别
get done 强调变化或遭遇,be done 兼顾动作与状态且不可随意互换。
• get + 过去分词:表示发生变化或遭遇某事(如 get hurt, get caught, get paid),常用口语。
• be + 过去分词:用于客观说明、正式程序,此时不能用 get 替换。
• be + 过去分词:可侧重状态(如 be interested in)。
• 例外:The door was closed 既可表示关门动作,也可表示门关着,不能只凭外形判断。
| 形式 | 常见含义 | 例子 | 辨别重点 |
|---|---|---|---|
| get + 过去分词 | 发生变化或遭遇某事 | My coat got caught in the door. | 侧重意外结果 |
| be + 过去分词 | 说明动作或处理过程 | The door was closed by the guard. | 可带 by 和具体时间 |
| be + 过去分词 | 描述当时状态 | The door is closed. | 不强调关门过程 |
| get + 形容词 | 变得 | He got interested in history. | 不是被动语态 |

包昨晚被偷了。 The door was closed by the guard at ten.
十点时门被警卫关上了。 The window is closed.
窗户是关着的。 He got interested in history later.

📌 北京真题 11 题原卷原题,答案按官方解析;单项填空 7 题;语法填空 4 空
The way the guests in the hotel influenced their evaluation of the service.
A. treatedB. were treatedC. would treatD. would be treated
看答案
✅ B. were treated(被动语态与时态一致)
先找主干:The way … influenced their evaluation,The way 是主语,influenced 是谓语。the way 后面省略了 that / in which,the guests ___ in the hotel 是修饰 the way 的定语从句。客人是“被对待”的,用被动;主句是过去时,从句也用一般过去时,故选 were treated。A. treated 是主动,变成“客人对待别人”;D. would be treated 是过去将来时,与已经发生的入住经历不符。
In the spoken English of some areas in the US, the "r" sounds at the end of the words .
A. are droppedB. dropC. are being droppedD. have dropped
看答案
✅ A. are dropped(被动语态)
分析句子结构,主语是 the "r" sounds,谓语动词缺失。由于发音不能主动执行“掉落”动作,而应是被人们省掉,故需用被动语态。此处描述的是一种普遍的语言现象,应使用一般现在时,因此选 are dropped。最容易误选的 B 选项 drop 是主动语态,主语与动词逻辑不通。
Experiments of this kind in both the U.S. and Europe well before the Second World War.
A. have conductedB. have been conductedC. had conductedD. had been conducted
看答案
✅ B. have been conducted(被动语态与时态辨析)
主语Experiments与动词conduct之间是被动关系,必须使用被动语态。句中well before the Second World War描述一个历史事实,强调此类实验在二战前就已开展且其结果或影响延续至今,故选have been conducted。A和C为主动语态,不符合逻辑;D项had been conducted虽有二战作为过去参照点,但此处侧重于对现状的铺垫而非单纯描述过去的过去,故不如B项恰当。
—Have you heard about that fire in the market?
— Yes, fortunately no one .
A. hurtB. was hurtC. has hurtD. had been hurt
看答案
✅ B. was hurt(被动语态)
首先看语境,对话讨论的是已经发生的火灾,且主语 no one 与动词 hurt(伤害)之间是被动关系,即“没有人受伤”。因此需用被动语态,选择 was hurt。时态上,火灾是过去发生的既定事实,用一般过去时即可。最容易误选 A,因为 hurt 在此处是及物动词,若用主动语态则表示“没有人伤害(别人)”,不符合逻辑。
Shakespeare’s play Hamlet into at least ten different films over the past years.
A. had been madeB. was madeC. has been madeD. would be made
看答案
✅ C. has been made(现在完成时的被动语态)
观察句末时间状语 over the past years,这是典型的现在完成时标志,表示从过去持续至今。主语 Hamlet 是戏剧,与 make 之间是被动关系,因此需用“have/has been done”结构,故选 has been made。最容易误选的是 B 选项 was made,它表示动作发生在过去某个具体时间点且已结束,而此处强调的是一段持续的时间跨度。
—Did you enjoy the party?
—Yes. We well by our hosts.
A. were treatedB. would be treatedC. treatedD. had treated
看答案
✅ A. were treated(一般过去时的被动语态)
首先看问句 Did you enjoy...,可知聚会已结束,需用过去时。再分析主语 We 与动词 treat(招待)的关系,我们是被主人招待,而非招待他人,因此需用被动语态。综合时态与语态,选择 were treated。最容易误选 C,因为它是一般过去时的主动语态,会导致句意变成“我们招待了主人”,逻辑不通。
The students have been working hard on their lessons and their efforts success in the end.
A. rewardedB. were rewardedC. will rewardD. will be rewarded
看答案
✅ D. will be rewarded(时态与被动语态)
首先分析句子结构,主语是 their efforts(他们的努力),谓语动词是 reward(回报)。根据关键词 in the end 可知此处应使用将来时。由于“努力”是被回报的,而非主动去回报他人,因此必须使用被动语态,故选 will be rewarded。最容易误选 C,因为 reward 在此处是及物动词,主语 efforts 与其之间是被动关系,不能用主动语态。

看答案
✅ are thrown(一般现在时被动语态)

- 看见‘正在被’却写 is been done;进行被动应为 is being done。
- 完成时被动漏掉 been,如 has finished 用于任务作主语;应为 has been finished。
- 写 This problem is easy to be solved;常规难易结构应为 is easy to solve。
- 将 be made do 写入作文;make 的被动宾补要恢复 to,写 be made to do。
- 短语变被动时漏介词,如 be laughed;表示‘被嘲笑’应为 be laughed at。

09 主谓一致找到真正的主语,再按结构和意义定单复数。
📝 北京怎么考:北京卷语法填空常在一般现在时、完成时和 there be 中考查主谓一致;长主语中的修饰成分容易干扰判断。本章收录北京卷语法填空 3 空(2021—2024 年中的 3 年)。
语法一致与主语中心词
谓语的数必须与主语中心词的语法形式保持一致。
• 找中心词:剥离介词短语、定语从句等修饰语。
• 距离无关:主语离谓语远近不改变一致关系。
• 现时:三单用 does 类,be 用 is/are,完成时用 has/have。
• 过去时:实义动词不分单复数;例外:was/were 要区分。
| 主语中心词 | 一般现在时普通实义动词 | be 动词 | 现在完成时中的 have |
|---|---|---|---|

意义一致与集合名词
主谓一致看意义:整体用单数,个体/群体用复数。
• family, team, class 等集合名词:整体用单数;例外:强调成员分别行动(英式英语)用复数。
• people, police, cattle:接复数谓语。
• news, mathematics, physics:接单数谓语。
| 主语 | 表达的意义 | 谓语形式 |
|---|---|---|

| family、team、class 等 | 成员分别行动 | 可用复数 |
| people、police、cattle、sheep | 多人或多头动物 | 复数 |
| news、mathematics、physics | 一个消息或一门学科 | 单数 |
| 表面特征 | 例词 | 判断 |
|---|---|---|

and 连接的并列主语
and连接的主语,不同对象用复数,同一对象或整体用单数。
• 不同人或事物 → 复数
• 同一人、同一事物或公认整体 → 单数
• each/every/no 限定两边单数名词 → 单数
• the singer and writer → 可能指一人
• the singer and the writer → 指两人
• 例外:需结合语境,不只数冠词
| 结构 | 含义 | 谓语形式 |
|---|---|---|
| A and B | 两个不同的人或事物 | 复数 |
| A and B | 同一个人、同一个事物或公认整体 | 单数 |
| every/each/no A and every/each/no B | 每一项分别被限定 | 单数 |
| the singer and writer | 可能为一人兼任两职 | 根据语境判断 |

黄油面包是我通常的早餐。
就近原则与 there be
谓语动词的单复数由离它最近的主语决定。
• 适用结构:either...or, neither...nor, not only...but also。
• there be 结构:be 动词与后面的真正主语一致。
• there be 接并列名词:按最近的名词定数。
• 例外:正式写作中混合单复数结构不顺时,可调整语序或改写。
| 结构 | 判断对象 |
|---|---|
| Either A or B + 谓语 | 看 B |
| Neither A nor B + 谓语 | 看 B |
| Not only A but also B + 谓语 | 看 B |
| There be + A and B | 看离 be 最近的名词 |

附加成分不改变主语
主语后的附加成分通常不决定谓语单复数,谓语跟核心主语一致。
• 附加成分由 with, along with, together with, as well as, rather than, including, except 等引导。
• 与 and 连接两个平等主语的结构不同。
• as well as 作连接成分时,重点在前项。
| 结构 | 决定谓语的成分 | 例示 |
|---|---|---|
| The monitor, with two classmates, … | The monitor | is |
| The teachers, as well as the headmaster, … | The teachers | support |
| The project, including the final report, … | The project | is |

• a number of + 复数名词:意为“许多……”,谓语用复数
• 例外:a large quantity of 等数量结构用法各异,不能仅凭有 number 就推广结论
| 短语 | 中心意义 | 谓语 |

不定代词与数量份额
不定代词作主语,单复数取决于词义或of后的名词。
• each, either, neither, everyone, someone, nothing 单独作主语 → 单数
• each of + 复数名词 → 单数
• 复数主语 + each → 复数(例外)
• all, some, most, 分数, 百分数 + of → 看of后名词(单数/不可数 → 单数;复数 → 复数)
• none of → 单数或复数均可,不宜设无语境的唯一答案题
| 主语结构 | 谓语形式 |
|---|---|
| each / either / neither | 单数 |
| everyone / somebody / nothing 等 | 单数 |
| each of / either of / neither of + 复数名词 | 通常为单数 |
| all / some / most / half of + 不可数名词或单数名词 | 单数 |

动名词短语、不定式短语或主语从句作主语,谓语用单数。
• 两个独立活动用 and 并列,用复数。
• what 从句:指单一事情用单数;例外:明确指多个事物且表语为复数时用复数(如 What we need are more chairs)。
• 形式主语 it 固定接单数谓语。
| 主语形式 | 常见一致结果 | 例示 |
|---|---|---|
| 一个动名词短语 | 单数 | Reading aloud helps. |
| 一个不定式短语 | 单数 | To understand is useful. |
| 两个动名词短语用 and 并列 | 复数 | Reading and writing help. |

她在会上所说的话让每个人都感到惊讶。 What we need are more chairs and a larger screen.
我们需要的是更多椅子和一块更大的屏幕。
时间距离整体与定语从句
主谓一致的核心是:找准谓语对应的真正主语。
• 时间、距离、金额看作整体 → 单数谓语。
• 例外:强调一个个单位 → 复数谓语。
• 定语从句关系代词作主语 → 谓语与先行词一致。
• one of the students who... → who指students,用复数。
• the only one of the students who... → 修饰one,用单数。
• 主句谓语 → 由主句主语决定。
| 结构 | 一致判断 | 例示 |
|---|---|---|
| 时间、距离、金额作为一个整体 | 单数 | Twenty minutes is enough. |
| one of the students who + 谓语 | who 指 students,用复数 | who volunteer… |
| the only one of the students who + 谓语 | who 指 one,用单数 | who lives… |
| 主句和定语从句 | 分别判断 | 主句看主句主语,从句看先行词 |

他是这些学生中唯一住在附近的人。
分数、百分数与数量表达
• 分数或百分数 + of + 名词作主语时,谓语通常根据 of 后的名词判断。
• of 后接复数名词时用复数谓语,接不可数名词或单数名词时用单数谓语。
• 分数或百分数单独作主语时通常看作一个数,接单数谓语。
• the percentage of + 名词的中心词是 percentage,因此接单数谓语。
• a large amount of + 不可数名词通常接单数谓语,a large number of + 复数名词通常接复数谓语。
| 主语结构 | 判断依据 | 谓语 |
|---|---|---|
| Two-thirds of the students | students 是复数 | are / were |
| Two-thirds of the water | water 是不可数名词 | is / was |
| Thirty percent of the applicants | applicants 是复数 | are / were |
| the percentage of the applicants | 中心词是 percentage | is / was |

通过考试的申请者所占百分比正在上升。 A large amount of water is needed for the experiment.
这个实验需要大量的水。
one of、the only one 与最高级
• one of + 复数名词单独作主语时,中心词是 one,因此接单数谓语。
• one of the students who… 中 who 通常指复数 students,因此定语从句用复数谓语。
• the only one of the students who… 中 who 指唯一的 one,因此定语从句用单数谓语。
• the + 最高级 + of + 复数名词表示“……中最……的一个”,中心是最高级表达,通常接单数谓语。
• one of the + 复数名词 + 关系副词从句时,谓语通常与前面的复数名词保持一致。
| 结构 | 判断对象 | 谓语 |
|---|---|---|
| one of my friends | one | 单数 |
| one of the students who + 谓语 | students | 复数 |
| the only one of the students who + 谓语 | one | 单数 |

• the rich、the poor、the elderly、the unemployed、the injured 等都常按复数处理。
• the + 形容词 + 单数名词表示一个具体的人或事物时,通常接单数谓语。
• the + 最高级 + of + 复数名词时,中心是“……中最……的一个”,通常接单数谓语。
• 判断时要区分“表示一类人”和“特指某个人或某个事物”。
| 结构 | 意义 | 谓语 |
|---|---|---|
| the + 形容词 + 复数名词 | 一类人 | 复数 |
| the rich / poor / elderly / unemployed | 一类人 | 复数 |
| the + 形容词 + 单数名词 | 一个具体的人或事物 | 单数 |

倒装句中的主谓一致
• Never、Seldom、Rarely、Hardly、Not only 等否定或限制性状语置于句首时,主句通常使用部分倒装。
• 倒装后真正的主语仍然决定谓语单复数,助动词本身不随主语加 -s。
• 第三人称单数用 has、does、did 等已经体现在助动词形式中。
• Not only 置于句首引起倒装时,常见完整结构为 Not only… but also…。
• So + 形容词 + be + 主语和 Such + be + 主语也使用部分倒装。
| 前置成分 | 倒装结构 | 例示 |
|---|---|---|
| Never / Seldom / Rarely / Hardly | 助动词或情态动词 + 主语 + 动词原形 | Never have I seen… |
| Not only | 助动词 + 主语 + 动词原形 | Not only did he… |
| Hardly + 过去时间 | had + 主语 + 过去分词 | Hardly had we arrived… |

这消息令人兴奋,以至于每个人都震惊了。
谓语形式与时态标志词速查
• 判断主谓一致前要先确定谓语属于哪一种时态和结构。
• 时间状语和标志词只是线索,最终还要结合语境和时间轴判断。
• 一般现在时中,第三人称单数普通实义动词用 -s/-es 形式,be 用 is,have 用 has。
• 进行时使用 be + doing,完成时使用 have/had + done,进行完成时使用 have/had been doing。
• 情态动词、助动词和完成时助动词不随第三人称单数变化。
• 一般将来时常用 will + 动词原形或 be going to + 动词原形。
| 时态 | 基本构成 | 常见标志词或时间状语 |
|---|---|---|
| 一般现在时 | do / does;am / is / are | always, usually, often, sometimes, seldom, never;every day / week / year |
| 现在进行时 | am / is / are doing | now, at the moment, currently;Look! Listen! |
| 一般过去时 | did;was / were | yesterday, last night / week / year;… ago;in 2020;just now |
| 过去进行时 | was / were doing | at 8 last night, this time last…;while, when |
| 现在完成时 | have / has done | already, yet, ever, never, just, so far, since, for, recently |
| 现在完成进行时 | have / has been doing | for the last…, all morning, recently, since |
| 过去完成时 | had done | by the end of last…, by then, before…;already…by… |
| 过去完成进行时 | had been doing | for…before, all day before;when + 过去事件 |
| 一般将来时 | will do;be going to do | tomorrow, next…;in + future period;soon |
| 将来进行时 | will be doing | at this time tomorrow, tomorrow morning / evening;when + 未来事件 |
| 将来完成时 | will have done | by the end of next…, by then;in + future period |
| 将来完成进行时 | will have been doing | by the end of next…;for…by then |
| 标志或结构 | 常见联想 | 使用提醒 |
|---|---|---|
| already, yet, ever, never, so far | 现在完成时或完成进行时 | 还要看动作是否与现在有关 |
| since + 时间点,for + 时间段 | 现在完成时或完成进行时 | 动作是否持续可由语境判断 |
| by + 过去时间 | 过去完成时 | by the end of last year 是常见信号 |
| by + 将来时间 | 将来完成时 | by the end of next year 是常见信号 |
| this morning / this afternoon | 一般过去时或现在完成时 | 若该时段已结束且仍与现在有关,优先考虑现在完成时 |
| when, while | 进行时 | 不是绝对规则,仍需看动作关系 |

- 把 with 当 and;with 引出的附加成分通常不改变核心主语的数。
- 见到 people 就写 is;people 表示人们时接复数谓语。
- 认为 every boy and every girl 是两个人群就用 have;这一结构通常用 has。
- 以为 there be 总用 is;要看 be 后的真正主语,完成时也要分 has been 与 have been。

10 非谓语动词先认句中功能,再判逻辑主语、语态与先后。
📝 北京怎么考:北京卷语法填空常考非谓语作定语、状语、宾语等,旧卷单项填空也常考;阅读理解中分词短语常使句子变长,写作须避免逻辑主语错位。本章收录北京卷单项填空 31 题(2008—2018 年中的 11 年)、语法填空 17 空(2019—2026 年中的 8 年)。
三种形式与六种功能
非谓语动词保留动作意义,但不独立承担谓语。
• to do:不定式
• doing:动名词或现在分词
• done:过去分词
• 判定:并列句、从句有各自谓语,不能仅凭句中已有动词就断定另一个为非谓语
• done:表示被动或完成;例外:不及物动词分词(如fallen)只表完成,不表被动
| 功能 | 常见形式 | 示例 |
|---|---|---|
| 主语 | to do / doing | To learn is to grow. / Swimming keeps us fit. |
| 宾语 | to do / doing | hope to win / enjoy reading |
| 表语 | to do / doing / done | My aim is to teach. / He looked excited. |
| 定语 | doing / done / to do | a sleeping baby / a broken cup / the first to arrive |
| 状语 | to do / doing / done | to save time / walking home / seen from above |
| 宾语补语 | to do / doing / done | ask him to wait / keep him waiting / have it repaired |
| 形式 | 典型语态或时间 | 高频识别信号 |
|---|---|---|
| to do | 通常表主动、尚未发生或具体目的 | 目的、打算、将要、为了 |
| doing | 通常表主动,也可表被动进行 | 正在、伴随、经常、令人 |
| done | 通常表被动、完成或状态 | 被、已经、感到、破损的 |
每天朗读有助于改善发音。 To help students prepare for the exam, the school has opened an online course.
为帮助学生备考,学校开设了一门在线课程。 The man standing by the window is our new teacher.
站在窗边的那个人是我们的新老师。 We had all the windows cleaned before the ceremony.
仪式前,我们请人把所有窗户擦干净了。
逻辑主语判断三步
逻辑主语即动作的执行者或承受者。
• 定语找被修饰名词,宾补找宾语,分词状语找主句主语。
• 还原搭配判断主动或被动(如 the books were ordered)。
• 比较非谓语与谓语动作的先后,结合句意选形式。
• 例外:目的不定式常与主语同指,也可由结构指定执行者。
| 结构 | 逻辑主语 | 判断依据 |
|---|---|---|
| the man standing there | the man | standing 的动作由 man 主动完成 |
| the man killed in the accident | the man | killed 表 man 承受动作 |
| It is important for him to succeed | him | for 后直接指出动作执行者 |
| His being absent worried us | him | 所有格 His 指出动名词的逻辑主语 |
| Weather permitting, we will go | the weather | 独立主格自带逻辑主语 |
| 非谓语动作与谓语动作的关系 | 常见形式 | 示例 |
|---|---|---|
| 先于谓语动作发生 | having done / to have done | Having checked the figures, she sent the report. |
| 与谓语动作同时发生 | doing | Walking home, I met an old friend. |
| 晚于或尚未发生 | to do | I have two letters to write. |
站在门口的学生们正在等老师。 The window broken by the boy has been repaired.
那个被男孩打破的窗户已经修好了。 To protect the environment, everyone should reduce waste.
为了保护环境,每个人都应减少浪费。 His being absent for a week worried the team.
他缺席一周使团队很担心。
主语与表语
动名词作主语常谈一般活动,不定式常谈具体安排或意图,两者有时可互换,不能理解成绝对界线。长不定式主语常后置,前用 it 作形式主语。for sb to do 指明动作执行者;It is kind/careless 等评价人的品质时常用 of sb to do。表语中,不定式常说明目标或安排,动名词可说明活动内容;分词常带形容词性质,-ing 常表‘令人……’,-ed 常表‘感到……’,也要按具体词义判断。
| 用法 | 常见形式 | 语义重点 | 示例 |
|---|---|---|---|
| 动名词作主语 | doing | 概括一般活动 | Learning a language takes time. |
| 不定式作主语 | to do | 把一件事作为目标 | To finish the task by Friday is our plan. |
| 形式主语结构 | It is ... for/of sb to do | 把较长主语后置 | It is useful for beginners to read aloud. |
| 表语 | to do | 目标或安排 | The next step is to call the police. |
| 表语 | doing | 活动内容 | Her hobby is painting. |
| 表语 | done | 人的感受或状态 | The child looked frightened. |
| -ing 形式 | -ed 形式 | 常见语义 |
|---|---|---|
| interesting | interested | 令人感兴趣/感到感兴趣 |
| exciting | excited | 令人兴奋/感到兴奋 |
| boring | bored | 令人厌烦/感到厌烦 |
| surprising | surprised | 令人惊讶/感到惊讶 |
| puzzling | puzzled | 令人困惑/感到困惑 |
学习一门语言需要坚持练习。 To finish the task by Friday is our plan.
星期五前完成任务是我们的计划。 It is useful for beginners to read aloud every day.
初学者每天大声朗读很有用。 It was thoughtful of you to save me a seat.
你给我留了座位,真周到。 After the interview, he looked excited, but the result was disappointing.
面试后他显得很兴奋,但结果令人失望。
动词与介词后的固定选择
作宾语时,先看搭配,决定用 doing 还是 to do。
• 介词后用 doing。
• look forward to / be used to / object to 中的 to 是介词,后接 doing。
• would like / love / prefer 接 to do。
• like / love / prefer 可接 doing 或 to do。
• 例外:上述词也可接名词或从句。
| 搭配类型 | 高频词或结构 | 常规形式 |
|---|---|---|
| 接 doing | admit、avoid、consider、delay、enjoy、finish、imagine、mind、miss、practise、risk、suggest | doing |
| 接 to do | afford、agree、decide、expect、fail、hope、manage、offer、plan、pretend、promise、refuse、wish | to do |
| 两者皆可 | like、love、prefer | doing / to do |
| would like / love / prefer | 表示更具体、更礼貌的选择 | to do |
| 短语接 doing | give up、feel like、have difficulty in、be busy in、look forward to、pay attention to | doing |
| 结构 | to 的性质 | 正确搭配 | 含义 |
|---|---|---|---|
| look forward to | 介词 | look forward to hearing from you | 期待收到你的消息 |
| be used to | 介词 | be used to working late | 习惯晚工作 |
| devote oneself to | 介词 | devote oneself to teaching | 致力于教学 |
| object to | 介词 | object to his being late | 反对他迟到 |
| want / hope / decide | 不定式符号 | want to leave / hope to succeed / decide to stay | 想要、希望、决定 |
| to be done | 不定式符号 | to be completed | 将被完成 |

她同意在学校门口见导游。 I am looking forward to receiving your suggestions.
我期待收到你的建议。 Would you mind opening the window?
你介意打开窗户吗?
两种形式意思不同
remember、forget、regret 等后面的 doing 与 to do 不能只按好听选择,要比较动作已经发生还是尚待发生;stop、try、mean、go on 的区别还涉及动作关系或词义。forget doing 常见于否定、疑问等语境,表示不记得做过某事。
| 动词 | 接 doing | 接 to do |
|---|---|---|
| remember | 记得做过 | 记住要做 |
| forget | 不记得做过 | 忘记要做 |
| regret | 后悔做过 | 遗憾地要做或说 |
| stop | 停止正在做的事 | 停下当前的事去做另一事 |
| try | 试着做,检验办法 | 努力设法做成 |
| mean | 意味着、需要 | 打算做 |
| go on | 继续同一件事 | 接着做另一件事 |
我记得锁过门了,但请记住要关窗。 I have forgotten to post the letter.

他停下说话来接电话。 After trying several methods, she finally opened the door.
试了几种方法后,她终于打开了门。 After finishing the report, he went on to prepare for the exam.
完成报告后,他接着准备考试。

• doing:主动,表正在发生或特征
• done:及物动词被动,或表完成
• being done:正在被做
• to do:将来、用途或待办
• to be done:将来被动
• 序数词、最高级修饰的名词后接不定式
• 例外:非被动关系不用done,需看动作是否尚待发生
| 形式 | 典型意义 | 示例 |
|---|---|---|
| doing | 主动、同时或一般特征 | a sleeping baby |
| done | 被动、完成或状态 | a broken cup |
| being done | 正在发生的被动动作 | the problem being discussed |

作状语的目的原因结果
非谓语动词作状语,核心在于区分目的、原因与结果,且逻辑主语与主句主语一致。
• to do:表目的;用于情感原因、too…to、enough to 结构。
• only to do:表意外结果。
• doing:表时间、原因、伴随、条件或自然结果。
• done:表被动背景下的时间、原因、条件、让步。
• 例外:自然结果分词可承接整个主句事件。
• 注意:结果状语并非全部用 to do。
| 语义关系 | 常用形式 | 示例 |
|---|---|---|
| 目的 | to do | to avoid further losses |
| 意外结果 | only to do | only to find the door locked |
| 自然结果 | doing | cutting off the village |
| 主动伴随或时间 | doing | walking along the river |
| 被动原因、条件或让步 | done | given enough time |
| 没有发生某动作 | without doing | without asking permission |
| 情境 | 推荐表达 | 含义 |
|---|---|---|
| 为了完成某事 | to do | 目的 |
| 努力后却发现 | only to do | 意外结果 |
| 前一动作直接造成后一结果 | doing | 自然结果 |
| 主语承受前一动作 | done | 被动背景 |

• being done:被动且正在进行
• having been done:被动且已先完成
• 过去分词没有加 having 的完成式

独立主格结构
独立主格 = 逻辑主语 + 非谓语等成分(整体作状语,交代时间/原因/条件或伴随)
• 逻辑主语通常不同于主句主语
• 两部分之间不用谓语式助动词直接连成两个句子
• 后项可用 doing, done, to do, 形容词, 副词或介词短语
• 例外:being 有时可省
• 例外:用了 because/when 等从属连词,应写成完整从句,不能随意拼接
| 类型 | 示例 | 作用 |
|---|---|---|
| 名词+doing | The teacher entering the room | 伴随动作 |

• 宾补形式由宾语决定:主动/进行用 doing,被动/完成用 done,尚待处理用 to do。
• 宾补也可接形容词、副词、介词短语。
• 例外:to do 可能由主句主语执行(如 with much homework to do),不改被动。
• 宾语用代词时,用宾格。
| 宾补形式 | 语义 | 示例 |
|---|---|---|

2. 一般现在时常表习惯、事实或真理,一般过去时把叙述时间放在过去。
3. 现在进行时和过去进行时都使用 be+doing,分别以现在和过去为参照。
4. 现在完成时和过去完成时使用 have/has/had+过去分词,分别联系现在和过去参照点。
5. 完成进行时使用 have/has/had been doing,强调动作持续到参照点。
6. 判断非谓语时间时,先找到句中的有限动词及其时态,再判断非谓语动作发生在其前、同时还是其后。
| 非谓语与有限动词的时间关系 | 常见形式 | 例句 |
|---|---|---|
| 发生在有限动词之前 | having done / to have done | He seemed to have left. |

📌 北京真题 48 题原卷原题,答案按官方解析;单项填空 31 题;语法填空 17 空
that she was going off to sleep, I asked if she’d like that little doll on her bed.
A. SeeingB. To seeC. SeeD. Seen
看答案
✅ A. Seeing(现在分词作原因状语)
主句是 I asked...,主语为 I。空格处引导的分词短语作原因状语,相当于 Because I saw...,表示因为看到她快要睡着了,所以才询问。主语 I 与 see 之间是主动关系,故选 Seeing。To see 表示目的,See 是原形不能直接作状语,Seen 是被动且逻辑不通,最易误选 D,但此处主语是动作的发出者而非承受者。
–Did the book give the information you needed?
–Yes. But it, I had to read the entire book.
A. to findB. findC. to findingD. finding
看答案
✅ A. to find(不定式作目的状语)
观察句子结构,主句是 I had to read the entire book,表示“我不得不读完整本书”,而空格处需要一个成分来解释读书的目的。选择 A. to find,构成不定式短语作目的状语,意为“为了找到(所需信息)”。D. finding 作为动名词或现在分词,在此处无法表达目的逻辑,且不能直接接在 But 之后引导目的。最容易误选 D,因为它混淆了目的状语与伴随状语的区别。
I feel greatly honored into their society.
A. to welcomeB. welcomingC. to be welcomedD. welcomed
看答案
✅ C. to be welcomed(不定式作形容词补足语)
句子主干是 I feel honored,其中 honored 是形容词,后面需要接不定式作补足语来解释感到荣幸的原因。分析逻辑关系,主语 I 与 welcome(欢迎)之间是被动关系,即“被欢迎进入”,因此必须使用被动形式 to be welcomed。A 选项 to welcome 是主动语态,逻辑不通;D 选项 welcomed 无法在形容词后直接作补足语。
It is worth considering what makes “convenience” foods so popular, and better ones of your own.
A. introducesB. to introduceC. introducingD. introduced
看答案
✅ C. introducing(动名词作宾语)
首先观察句子结构,It is worth doing sth. 是固定句型,意为“值得做某事”。此处 worth 后面接了 considering 引导的宾语,随后出现并列连词 and,连接的是另一个与 considering 平行的成分。因此,此处应填入 introducing 以保持结构一致,共同作为 worth 的宾语。最容易误选 A,因为学生常习惯性地寻找谓语动词,但此处并非主句谓语,不能用谓语形式。
For breakfast he only drinks juice from fresh fruit on his own farm.
A. grownB. being grownC. to be grownD. to grow
看答案
✅ A. grown(过去分词作后置定语)
句子主干是 he drinks juice,空格处需要一个成分来修饰 fruit。fruit 与 grow 之间是被动关系,且水果是先种植好才被饮用的,具有完成感,因此选用过去分词 grown 作后置定语。此处 grow 是及物动词,表示“种植水果”。最容易误选 D,因为 to grow 表示目的或将来,与语境不符。
All of them try to use the power of the workstation information in a more effective way.
A. presentingB. presentedC. being presentedD. to present
看答案
✅ D. to present(不定式作名词补足语)
首先分析句子结构,主语 All of them,谓语 try to use,宾语 the power of the workstation,主干完整。空格处需修饰名词 power,说明这种“能力”的具体内容,因此选用 to present 作为不定式补足语,表示工作站的能力是用于“呈现信息”。A 选项 presenting 为现在分词,不能在此结构中表示功能或目的,且不符合名词补足语的习惯用法,故排除。
twice, the postman refused to deliver our letters unless we changed our dog.
A. Being bittenB. BittenC. Having bittenD. To be bitten
看答案
✅ B. Bitten(过去分词作状语)
首先分析句子结构,主句主语是 the postman,空格处为非谓语动词作状语。邮递员与 bite(咬)之间是被动关系,且被咬发生在拒绝投递之前,因此使用过去分词 Bitten 表示被动和完成。Bitten 在此处相当于 (Having been) bitten。最容易误选 A,因为 Being bitten 表示正在被咬或一般的被动,而此处强调的是此前被咬两次导致的结果,且过去分词作状语时通常省略 being。
at my classmates' faces, I read the same excitement in their eyes.
A. LookingB. LookC. To lookD. Looked
看答案
✅ A. Looking(现在分词作状语)
先看句子结构,主句是 I read the same excitement...,逗号前是状语部分。主语 I 与 look 之间是主动关系,且动作与主句同时发生,因此选用 Looking 表示伴随状态。注意,Looked 是过去分词形式,单独放在句首不能构成合法的伴随状语,故不能选。
I'm calling to enquire about the position in yesterday's China Daily.
A. advertisedB. to be advertisedC. advertisingD. having advertised
看答案
✅ A. advertised(过去分词作后置定语)
首先分析句子结构,主句是 I'm calling to enquire...,空格处需要一个词来修饰名词 position。分析 position 与 advertise 的关系,职位是被刊登的,属于被动关系,因此选用过去分词 advertised 作后置定语,相当于 which was advertised。最容易误选 C,因为 advertising 表示主动且持续,职位不能主动刊登自己。
It’s important for the figures regularly.
A. to be updatedB. to have been updatedC. to updateD. to have updated
看答案
✅ A. to be updated(不定式的被动语态)
It 是形式主语,真正的主语是 for the figures to … regularly;for 引出的 the figures 是不定式的逻辑主语。数据是“被更新”的,要用被动的 to be updated;regularly 表示经常性的动作,用不定式一般式即可,故选 A. to be updated。C. to update 是主动,变成“数据去更新别的东西”;B、D 的完成式表示动作已经先完成,和“定期更新”不符。
Sit down, Emma. You will only make yourself more tired, on your feet.
A. to keepB. keepingC. having keptD. to have kept
看答案
✅ B. keeping(现在分词作伴随状语)
句子主干是 You will only make yourself more tired,后面逗号隔开的部分是对主句动作状态的补充。这里用 keeping 表示在“让自己疲惫”的同时,处于“一直站着”的状态,构成伴随状语。因为主语 You 与 keep 之间是主动关系,且动作与主句同步,故选 keeping。A 项 to keep 表示目的或结果,逻辑不通,是学生最容易误选的干扰项。
One learns a language by making mistakes and them.
A. correctsB. correctC. to correctD. correcting
看答案
✅ D. correcting(动名词作介词宾语)
首先观察句子结构,关键词是介词 by。by 在这里表示“通过……方式”,其后需要接动名词形式。句子中 by 后面连接了两个动作,由 and 连接,因此这两个动作必须保持平行结构。第一个动作是 making,所以空格处必须填入对应的 correcting。最容易误选 A,因为学生常习惯性地根据主语 One 寻找谓语动词,而忽略了 by 的介词属性。
with care, one tin will last for six weeks.
A. UseB. UsingC. UsedD. To use
看答案
✅ C. Used(过去分词作状语)
首先分析句子结构,主句是 one tin will last for six weeks,主语是 one tin(罐头)。空格处为非谓语动词作状语,需判断主语 tin 与动词 use 的关系。由于罐头是被使用的,因此应选用过去分词 Used 表示被动。Used with care 相当于 If it is used with care。最容易误选 B,因为 Using 表示主动,罐头不能主动使用。
Volunteering gives you a chance lives, including your own.
A. changeB. changingC. changedD. to change
看答案
✅ D. to change(不定式作后置定语)
首先分析句子结构,主语是 Volunteering,谓语是 gives,宾语是 a chance。此处需要一个成分来修饰名词 chance,表示“改变生活的机会”。根据习惯搭配,chance 后常接动词不定式作定语,因此选择 to change。A 选项 change 是动词原形,不能直接跟在名词后作定语;B 选项 changing 虽然是非谓语,但此处不符合 chance 的固定搭配习惯。
the course very difficult, she decided to move to a lower level.
A. FindB. FindingC. To findD. Found
看答案
✅ B. Finding(现在分词作原因状语)
主句是 she decided to move...,主语是 she。空格位于句首且后接宾语 the course,说明此处需要非谓语动词作状语。由于主语 she 与 find 之间是主动关系,且“觉得课程难”是“决定降级”的原因,因此选用 Finding 表示原因状语。A 选项 Find 是动词原形,不能直接在句首作状语;D 选项 Found 是过去分词,表示被动或完成,而此处主语是主动发出“觉得”这个动作,故不符合逻辑。
When we saw the road with snow, we decided to spend the holiday at home.
A. blockB. to blockC. blockingD. blocked
看答案
✅ D. blocked(非谓语动词作宾补)
句子结构为 see + 宾语 + 宾语补足语。观察宾语 the road 与动词 block(阻塞)的关系,路是被雪阻塞的,两者是被动关系,因此需用过去分词 blocked 作补足语。注意 see 是感官动词,其补足语常用原形或现在分词表示主动/进行,但此处强调状态且为被动,故选 D。最容易误选 C,因为 blocking 表示路在主动阻塞某物,不符合逻辑。
Last night, there were millions of people the opening ceremony live on TV.
A. watchB. to watchC. watchedD. watching
看答案
✅ D. watching(现在分词作后置定语)
首先分析句子结构,主句是 there were millions of people,谓语动词是 were,句子主干已完整。空格处需要一个成分来修饰 people,表示“正在观看仪式的人”。watching 作为现在分词,在句中作后置定语,相当于省略了关系代词的定语从句 (who were watching)。因此选择 D. watching。最容易误选 C. watched,因为 people 与 watch 之间是主动关系而非被动。
There are still many problems before we are ready for a long stay on the Moon.
A. solvingB. solvedC. being solvedD. to be solved
看答案
✅ D. to be solved(不定式作后置定语)
句子主干是 There are many problems,空格处需填入定语修饰 problems。根据语境,这些问题是“将来需要被解决”的,表示将来或目的时,应用不定式作定语;且问题与 solve 是被动关系,故选 to be solved。注意 A 选项 solving 表示主动且进行,不能修饰 problems,容易误选。
The film star wears sunglasses. Therefore, he can go shopping without ..
A. recognizingB. being recognizedC. having recognizedD. having been recognized
看答案
✅ B. being recognized(动名词的被动形式)
首先看介词 without,其后需接动名词形式。根据语境,电影明星戴墨镜是为了不“被认出”,而非他去认别人,因此需用被动语态。being recognized 是动名词的被动形式,符合“介词 + 动名词被动”的结构。最容易误选 A,因为 recognizing 是主动含义,表示“认出某人”,与句意相反。
the early flight,we ordered a taxi in advance and got up very early.
A. CatchingB. CaughtC. To catchD. Catch
看答案
✅ C. To catch(不定式作目的状语)
句子主句是 we ordered a taxi...,主语和谓语完整,空格处为非谓语动词作状语。根据语境,提前打车和早起是为了“赶上早班飞机”,表示目的,因此选 To catch。To catch 在句中作目的状语,相当于 In order to catch。最容易误选 A,因为 Catching 表示伴随或结果,逻辑上不通,不能说“赶上飞机”导致了“提前打车”。
The park was full of people themselves in the sunshine
A. having enjoyedB. enjoyedC. enjoyingD. to enjoy
看答案
✅ C. enjoying(现在分词作后置定语)
首先分析句子结构,主句是 The park was full of people,空格处需要一个成分来修饰 people。由于 people 与 enjoy 之间是主动关系,且动作在此时发生,因此使用现在分词 enjoying 作后置定语(或伴随状语),表示“人们正在享受阳光”。选项 B enjoyed 是过去分词,表示被动或完成,与语境不符,故排除。
If for the job, you’ll be informed soon.
A. to acceptB. acceptC. acceptingD. accepted
看答案
✅ D. accepted(过去分词作状语)
观察句子结构,If 引导的从句缺少主语和谓语。根据主句主语 you 可推断,从句主语也是 you,且 you 与 accept(接纳/录取)之间是被动关系。因此需用过去分词 accepted 表示被动,该结构相当于 If you are accepted 的省略形式。注意 A 选项 to accept 表示目的或将来,不符合此处表示条件的语境。
it easier to get in touch with us, you’d better keep this card at hand.
A. MadeB. MakeC. MakingD. To make
看答案
✅ D. To make(不定式作目的状语)
观察句子结构,主句是“you'd better keep this card at hand”,主谓宾完整。空格处位于句首且与主句有逻辑因果关系,表示采取某种行动的目的。为了表达“为了使……”,应使用动词不定式,故选 To make。最容易误选 C,因为 Making 引导的动名词或分词短语通常表示伴随或原因,而此处强调的是目的,逻辑上不成立。
over a week ago, the books are expected to arrive any time now.
A. OrderingB. To orderC. Having orderedD. Ordered
看答案
✅ D. Ordered(过去分词作定语)
观察句子结构,逗号前是过去分词短语作定语,修饰主语 the books,相当于 the books, which were ordered over a week ago。分析 books 与 order 的关系,书是被订购的,具有被动含义,因此选用过去分词 Ordered。最容易误选 C,因为 Having ordered 是主动形式,要求主语必须是“订书的人”而非“书”本身。
Newly-built wooden cottages line the street, the old town into a dreamland.
A. turnB. turningC. to turnD. turned
看答案
✅ B. turning(现在分词作伴随状语)
首先分析句子结构,主句是 Newly-built wooden cottages line the street,结构完整。逗号后需要填入非谓语动词作状语。由于木屋(cottages)与 turn 之间是主动关系,且表示结果或伴随状态,因此使用 turning。最容易误选 A,但一个简单句不能在没有连词的情况下出现两个谓语动词,故排除。
Many airlines now allow passengers to print their boarding passes online their valuable time.
A. saveB. savingC. to saveD. saved
看答案
✅ C. to save(不定式作目的状语)
句子主干为 Many airlines allow passengers to print their boarding passes,结构完整。空格处需要填入一个成分来修饰整个动作,表示航空公司允许乘客在线打印登机牌的“目的”。因此选择 to save 表示“为了节省”。最容易误选 B,因为 saving 作结果状语通常表示自然而然产生的结果,而此处强调的是主观目的,且 to save 在此类句型中更为地道。
The national park has a large collection of wildlife, from butterflies to elephants.
A. rangingB. rangeC. to rangeD. ranged
看答案
✅ A. ranging(现在分词作后置定语)
句子主干为 The national park has a large collection of wildlife,逗号后为补充说明。wildlife 与 range 之间是主动关系,且 range from... to... 为固定搭配,故使用现在分词 ranging 作后置定语修饰 wildlife。B 项 range 为动词原形,不能在无连词的情况下直接作谓语;D 项 ranged 为过去分词,表示被动,不符合语境。
Jim has retired, but he still remember the happy time with his students.
A. to spendB. spendC. spendingD. spent
看答案
✅ D. spent(过去分词作后置定语)
句子主干是 Jim remembers the happy time。空格处需填入非谓语动词修饰 time。由于 time 与 spend 之间是被动关系(时间是被度过的),因此选用过去分词 spent 作后置定语,相当于省略了 which was。最容易误选 C,因为 spending 表示主动或进行,而时间不能主动度过。
along the old Silk Road is an interesting and rewarding experience
A. TravelB. TravelingC. Having traveledD. Traveled
看答案
✅ B. Traveling(动名词作主语)
观察句子结构,is 是谓语动词,空格处位于句首,需要一个名词性成分充当主语。Traveling 作为动名词,表示“旅行这件事”,符合语法要求且语义自然,因此选择 B。A 选项 Travel 虽然可作名词,但通常指抽象的旅行概念,在此处接 along... 这种具体路径时,需用动名词形式。C 选项 Having traveled 强调“已经完成”的动作,与表达普遍体验的语义不符。D 选项 Traveled 是过去分词,不能独立作主语。
During the Mid-Autumn Festival, family members often gather together a meal, admire the moon and enjoy moon cakes.
A. shareB. to shareC. having sharedD. shared
看答案
✅ B. to share(不定式作目的状语)
句子主干是 family members gather together,结构完整。空格处需要一个成分来修饰 gather together,表示聚集在一起的目的是为了做什么。选择 to share 表示“为了分享”,与后面的 admire 和 enjoy 构成平行结构,共同描述节日活动。A 选项 share 是动词原形,不能在没有连词的情况下直接跟在谓语动词后面;C 和 D 选项的非谓语形式不符合此处表达目的的语境。
Ordinary soap, correctly, can deal with bacteria effectively.
A. usedB. to useC. usingD. use
看答案
✅ A. used(过去分词作条件状语)
主干是 Ordinary soap can deal with bacteria effectively,逗号隔开的 ___ correctly 是插入的状语,相当于 if it is used correctly(如果使用得当)。肥皂是“被使用”的,用过去分词表被动,故选 A. used。C. using 表示主动,肥皂不会自己使用;B. to use 表目的或将来,意思不对;D. use 是动词原形,句子已有谓语 can deal with,不能再加谓语。

⚠️ 易错点
- 只看句中已有谓语就排除其他谓语;先检查是否有并列连词或从句边界。
- 把 doing 永远等同于‘正在’;动名词常表示一般活动,分词也可表示特征或结果。
- 把 done 当作过去时;过去分词是非谓语形式,本身不能独立构成一般过去时谓语。
- 分词状语的执行者写错,如 Walking home, the rain began;应让行走的人作主句主语,或改用完整时间从句。
- 在 look forward to 后用动词原形;to 是介词,要接名词或 doing。
- 把 remember doing 与 remember to do 混用;前者回忆已做,后者记住待做。
- with 后一律用 doing;必须判断该宾语是执行动作、承受动作还是还有待办事项。
- 看到名词承受动作就一律选 done;正在被做可用 being done,尚待被做可用 to be done。

11 情态动词情态表达能力、许可、义务、意愿与推测。
📝 北京怎么考:北京旧卷单项填空考查情境中的能力、许可、必要性和可能性;现行阅读与写作仍需辨别情态强弱,语法填空遇到情态结构要注意后接动词原形。本章收录北京卷单项填空 11 题(2008—2018 年中的 11 年)。
基本形式与时间关系
情态动词后接动词原形(不带to),且形式不随主语变化。
• 否定直接加not,疑问将情态动词提前。
• 例外:need、dare兼有实义动词用法,须另判。
• could、might、would不一定表示过去,也可表示委婉、较小可能性或虚拟。
• 后接be doing:推测正在发生。
• 后接have done:谈论过去(非现在完成时谓语)。
| 类别 | 肯定结构 | 否定结构 | 疑问结构 |
|---|---|---|---|
| 一般情态动词 | 主语 + 情态动词 + 动词原形 | 主语 + 情态动词 + not + 动词原形 | 情态动词 + 主语 + 动词原形? |
| need/dare 作情态动词 | Need/Dare + 主语 + 动词原形 | need/dare + not + 动词原形 | Need/Dare + 主语 + 动词原形? |
| 结构 | 时间落点 | 常见功能 | 例句 |
|---|---|---|---|
| 情态动词 + be doing | 说话时常正在进行 | 推测现在正在发生的动作 | He may be waiting outside. |
| 情态动词 + have done | 过去 | 推测过去发生过的动作 | She must have left already. |
| 情态动词 + have been doing | 过去一段时间 | 推测过去持续进行的动作 | They could have been working all morning. |
她能解决这个问题,但她可能需要更多时间。 He might be waiting at the other entrance.
他也许正在另一个入口等候。 The keys must have been lost on the way.
钥匙一定是在路上丢了。 Would you mind opening the window?
你介意打开一下窗户吗?
can 与 could
can/could 核心区分:能力、许可、可能性及委婉程度。
• can:表能力、许可或可能性。
• could:表过去能力或现在委婉请求。
• 过去某次实际成功:用 was/were able to 或 managed to。例外:感官、认知动词及否定句可用 could。
• 否定/疑问:用于推测,can’t 表示“不可能”。
• 请求:could 比 can 更客气。
• 回答现在许可:用 can。注意:问句用 could 不代表是过去时。
| 用途 | can | could |
|---|---|---|
| 能力 | can swim | could swim when young |
| 请求 | Can you help me? | Could you help me? |
| 可能性 | It can happen. | It could be true. |
| 否定推测 | It can’t be true. | It couldn’t have happened. |
| 表达 | 例句 | 说明 |
|---|---|---|
| was/were able to do | He was able to solve the problem. | 过去一次成功做到 |
| managed to do | She managed to finish on time. | 克服困难后完成 |
| could + 感官或认知动词 | I could smell smoke in the air. | 过去具备某种感官或认知能力 |
这个小男孩现在能数到十了。 At that time, few girls could ride a bicycle.
那时会骑自行车的女孩很少。 Could you tell me how to get to the station?
你能告诉我怎样去车站吗? Despite the heavy traffic, she was able to reach the meeting on time.
尽管交通拥堵,她还是准时到达了会场。 People can find useful information on the Internet.
人们可以在网上找到有用的信息。
may 与 might
may/might 常表示没有把握的推测,might 可显得更不确定或更委婉,但不能机械对应固定概率。may 可用于较正式的许可,May I…? 是征求许可;Might I…? 更委婉且较少用。may not 可表示‘可能不’,在许可语境中也可表示‘不准’,要看语境;may/might as well do 表示‘不妨做’,May + 主语 + 原形还可用于祝愿。
| 功能 | 常用表达 | 含义或语气 |
|---|---|---|
| 许可 | May I use your pen? | 我可以借用你的笔吗? |
| 推测 | He may/might be right. | 他可能是对的 |
| 建议 | We may/might as well go. | 我们不妨去 |
| 祝愿 | May you succeed! | 愿你成功 |
| 形式 | 许可语境 | 推测语境 |
|---|---|---|
| may not | 不准、不可以 | 可能不 |
| might not | 较少用于表示许可 | 可能不 |
| may/might | 可以 | 可能 |
博物馆今天可能不开放,我们先查一下。 May I ask you a quick question?
我可以问你一个问题吗? We might as well walk, since the bus has just left.
既然公共汽车刚走,我们不妨步行。 May all your hard work bring good results!
愿你所有的努力都结出好成果!
must 与 have to
must 表示必须、强烈要求,也可表示很有把握的肯定推测。have to 常突出外在要求,并能灵活表达过去、将来,如 had to、will have to;must 与 have to 的主客观区别是常见侧重,不是绝对界线。mustn’t 表禁止,否定‘必须’的必要性要用 needn’t 或 don’t have to。回答 Must I…?:肯定可用 Yes, you must;否定通常用 No, you needn’t/don’t have to。must 还可表‘偏要、非得’,含不满。
| 比较项 | must | have to |
|---|---|---|
| 语义侧重 | 说话人认为必须,或规则、道理要求 | 客观条件或外在规定要求 |
| 形式 | must + 动词原形 | has/have/had to + 动词原形 |
| 否定 | mustn’t = 禁止 | don’t/doesn’t/didn’t have to = 不必 |
| 强推测 | must be = 一定、准是 | 无直接对应形式 |
| 问句 | 肯定回答 | 否定回答 |
|---|---|---|
| Must I...? | Yes, you must. | No, you needn’t/don’t have to. |
| Do I have to...? | Yes, you do. | No, you don’t have to. |

所有申请者都必须提交网上表格。 You must not use this entrance without a ticket.
没有车票,你不得使用这个入口。 The lights are on, so someone must be inside.
灯亮着,所以里面一定有人。
should 的建议与预期
should 和 ought to 主要表示建议、责任和按理推测。
• ought to 表示类似的“应该”,ought 后必须有 to。
• should 表预期时译为“按理应该”,肯定推测语气弱于 must。
• should 可表达惊讶,如 It is strange that…should…
• 建议、要求等从句中 (should) do 是虚拟结构,非过去时。
• had better do 表最好,否定为 had better not do。
| 功能 | 例句 | 含义 |
|---|---|---|
| 建议或责任 | You should apologize. | 你应该道歉 |
| 按理预期 | The parcel should arrive tomorrow. | 包裹按理明天会到 |
| 个人打算 | You had better leave now. | 你最好现在离开 |
| 惊讶 | It is strange that he should know. | 他竟然知道,真奇怪 |
| 表达 | 基本结构 | 典型侧重 |
|---|---|---|
| should | should do | 建议、责任或按理预期 |
| ought to | ought to do | 常与 should 意义相近 |
| had better | had better (not) do | 提出较直接、较紧迫的个人建议 |
如果不耽搁,包裹按理应在周五之前送到。 You ought to check the source before sharing the news.
转发消息前,你应该核查来源。 You had better leave now or you will miss the train.
你最好现在离开,否则会错过火车。 It is strange that he should know the answer without being told.
没有人告诉他,他却知道答案,真奇怪。
need 的两种用法
need 既能当情态动词(直接加原形),也能当实义动词(加 to do)。
• 情态动词:用于否定/疑问,不加-s,不用do,后接原形(如 needn’t go, Need I go?)。
• 实义动词:有 needs/needed 变化,否定/疑问借助 do/does/did,后接 to do。
• 实义动词被动:用 need doing 或 need to be done。
• needn’t have done:过去做了,但其实不必。
• didn’t need to do:当时没必要,不保证是否做了。
| 身份 | 后接结构 | 典型例句 | 判断提示 |
|---|---|---|---|
| 情态动词 | 动词原形 | You need not go. / Need I go? | 不加 to,不用 do 助问 |
| 实义动词 | to do | She needs to rest. | 有 needs/needed,用 do 助问 |
| 事物需被处理 | doing / to be done | The wall needs painting. | 主语承受处理 |
| 结构 | 核心含义 | 不能直接推出 |
|---|---|---|
| needn’t have done | 过去做了,但本来没有必要 | 不能只理解为‘过去没有必要’ |
| didn’t need to do | 过去当时没有必要 | 不能判断动作是否实际发生 |
| mustn’t have done | 不作为‘过去一定没做’的常规表达 | 该意思通常用 can’t/couldn’t have done |
你现在不必回答,但每个人都需要在周一之前答复。 Does she need to work overtime?
她需要加班吗? The wall needs painting before we move in.
我们搬进去前这面墙需要粉刷。 You needn’t have brought lunch; we have already ordered food for everyone.

dare 的两种用法
dare 既可作情态动词也可作实义动词,核心区别在于是否用 do 帮助及是否接 to。
• 情态动词:见于否定、疑问、条件语境,后接原形,不用 do。例:dare not ask / Dare he ask?
• 实义动词:有 dares/dared 变化,后接 to do,否定疑问用 do。
• 例外:实义动词在否定等语境中 to 可省略。例:doesn't dare (to) ask
• dare sb to do:激某人做。
• How dare you…!:强烈责备。
• I dare say:固定说法,表示“我想、大概”。
| 身份或用法 | 结构 | 例句 |
|---|---|---|
| 情态动词 | dare + 动词原形 | dare not ask / Dare he ask? |
| 实义动词 | dare to do | She dared to speak. |
| 实义动词的否定 | do/does/did + dare (to) do | He didn’t dare (to) interrupt. |
| 固定搭配 | dare sb to do | I dare you to try it. |

他敢问这样的问题吗? How dare you speak to her like that!
你怎么敢那样对她讲话! I dare say the weather will improve tomorrow.
我想明天天气会好转。
will 与 would
will/would 核心在于区分“意愿/习惯”与“时态/虚拟”。
• will:表意愿、请求、习惯性行为或事物特性。
• won’t:表将来否定,或指“不肯”、机器“怎么也不工作”。
• would:表过去反复行为、委婉请求、过去将来或虚拟。
• would 表过去习惯:用于动作,有过去背景。
• used to:用于过去动作或状态,暗示现在不同。

| 过去情况 | would | used to |
|---|---|---|
| 反复动作 | would do,需有过去语境 | used to do |
| 过去状态 | 较少直接用 would be | used to be |
| 现在是否延续 | 不自动表示已经不再 | 通常暗示现在情况不同 |

我们过去住在河边的一个小村庄里。 Would you mind closing the window?
你介意关一下窗户吗? I would rather stay at home than go shopping today.
今天我宁愿待在家里,也不愿去购物。
shall 的提议与规定
shall 的核心用法是:第一人称提议,非第一人称规定。
• Shall I/we...?:征求意见或提出帮助。
• 第二/三人称(正式规定/条款):表示义务。
• 特定语境:表示承诺、警告或决心。
• I/we shall do:表示将来,较正式,日常常用 will。

| 正式规定 | Participants shall wear identity badges. | 参加者须佩戴身份牌 |

| 过去条件未实现 | if + had done, would have done | If I had known, I would have helped. |
你本该备份文件的,现在文件丢了。 You shouldn’t have told him about the plan.

如果我当时收到邀请,就会和你们一起参加了。
情态动词的时态指向
• 情态动词没有现在式、过去式之分,could、might、would 的时间指向主要由语境决定。
• can/could do 可指现在能力或过去一般能力,要看是否出现过去时间状语。
• may/might do 可指现在或将来的可能,will do 可指现在的预测或将来安排。
• would do 可指过去反复习惯、过去将来,也可用于现在的礼貌请求。
• 转述过去将来时常说 said + would do,这是句法转换,不是 would 的固定过去式。
• 情态动词加 have done 把判断落在过去,加 be doing 常把判断落在现在。
| 表达 | 可能的时间指向 | 判断线索 |
|---|---|---|
| can/could do | 现在能力或过去一般能力 | 有无过去时间背景 |
| may/might do | 现在或将来可能 | 语境、结果或将来安排 |
| will do | 现在的预测或将来 | 说话时刻与时间状语 |
| would do | 过去习惯、过去将来或现在礼貌请求 | 过去语境、间接引语或请求语气 |
| must/should do | 现在的推断或预期 | 现有证据或常理 |
| modal + have done | 过去 | 对已经发生之事的推测或评价 |

情态动词后的常见结构
• 情态动词后接动词原形,这是最基本的结构。
• modal + be doing 常表示现在正在进行或对现在动作的推测。
• modal + have done 常表示过去已经发生的动作或对过去的推测。
• modal + have been doing 常表示过去持续进行的动作。
• modal + be + 过去分词 可构成被动结构,modal + have been + 过去分词 可表示完成被动或过去推测。
• modal + be + 形容词 可表示可能性、义务或状态,modal + there be 可表示某种情况可能存在。
| 结构 | 时间或语态 | 常见意义 | 例句 |
|---|---|---|---|
| modal + do | 由语境决定 | 能力、许可、推测等 | She can solve it. |
| modal + be doing | 现在进行 | 现在动作或现在推测 | He may be waiting. |
| modal + have done | 完成形式 | 过去动作或过去推测 | They must have left. |
| modal + have been doing | 完成进行 | 过去持续动作 | It could have been raining. |
| modal + be + 过去分词 | 被动 | 被动动作或状态 | The problem can be solved. |
| modal + have been + 过去分词 | 完成被动 | 过去被动动作或推测 | The keys must have been stolen. |
| modal + be + 形容词/there be | 状态或存在 | 可能、义务或情况 | This may be useful. / There may be a problem. |
他也许正在正门外等候。 The keys must have been lost on the way.
钥匙一定是在路上丢了。 The road could have been closed because of the snow.
道路可能因降雪而封闭了。 The machine must have been running for hours.
这台机器一定已经运行了好几个小时。 There may be a delay because of the heavy rain.
由于大雨,可能会延误。
情态动词的否定与疑问
• 情态动词的否定式直接在情态动词后加 not,不用 do/does/did 助问。
• mustn’t 表示禁止,needn’t/don’t have to 表示没有必要。
• may not 可表示‘可能不’,在许可语境中可表示‘不准’。
• might not 通常表示‘可能不’,can’t 表示‘不可能’,couldn’t 可用于现在或过去。
• can/could/may/would 构成请求疑问句时,把情态动词放在主语前。
• 回答 Must I...? 的否定常用 No, you needn’t/don’t have to,不能答成 No, you mustn’t。
| 肯定词 | 常见否定形式 | 核心区别 |
|---|---|---|
| must | mustn’t | 禁止 |
| need | needn’t / need not | 没有必要 |
| have to | don’t/doesn’t/didn’t have to | 没有必要 |
| may | may not | 可能不;在许可语境中可表示不准 |
| can | cannot / can’t | 不可能或不能 |

建议、要求等从句中的 should
• suggest、advise、propose、request、require、order、demand 等后接 that 从句时,从句常用 (should) + 动词原形。
• should 在这些从句中不是过去时,而是虚拟语气标志,保留原形即可。
• suggest doing 表示建议做某事,不能用 suggest to do 或 suggest sb to do。
• important、necessary、essential、desirable 等形容词后的 that 从句也常用 (should) + 动词原形。
• suggestion、proposal、requirement 等名词后的 that 从句同样可用 (should) + 动词原形。
• 这些从句不要求把谓语改成过去时,是否使用 should 要看从句结构和语境。
| 触发词 | 从句结构 | 例句 |
|---|---|---|
| suggest/advise/propose/request/require/order/demand | that + (should) + 主语 + 动词原形 | suggest that we (should) meet |
| important/necessary/essential/desirable | that + (should) + 主语 + 动词原形 | It is necessary that he arrive early. |

📌 北京真题 11 题原卷原题,答案按官方解析;单项填空 11 题
John promised his doctor he not smoke, and he has smoked ever since.
A. mightB. shouldC. couldD. would
看答案
✅ D. would(情态动词的过去将来时)
首先观察主句谓语 promised 是过去时,且后面接的是一个宾语从句。在过去的时间点对未来做出承诺,需要使用情态动词的过去将来时,因此选择 would。would not smoke 表示在当时看来将不再抽烟。最容易误选的是 should,虽然 should 有“应当”之意,但此处强调的是对未来的承诺而非义务,且 would 是 promise 的标准搭配。
One of the few things you say about English people with certainty is that they talk a lot about the weather.
A. needB. mustC. shouldD. can
看答案
✅ D. can(情态动词辨析)
主语是包含定语从句的名词短语,其中 you ___ say... with certainty 是修饰 things 的定语从句。根据语境,这里强调的是在客观条件下“能够”肯定地说出某事,因此用 can 表示能力或可能性。A 选项 need 若作情态动词通常用于否定句或疑问句,肯定句中需用 need to say;B 选项 must 表示强制性,C 选项 should 表示义务或建议,均与语境不符。
---Good morning. I've got an appointment with Miss Smith in the Personnel Department.
--Ah, good morning. You be Mrs. Peters.
A. mightB. mustC. wouldD. can
看答案
✅ B. must(情态动词表示推测)
首先看对话语境,第一人提到与人事部的史密斯小姐有约,第二人基于此信息进行推断。因为预约的人选通常是确定的,此时语气坚定,应选 must 表示“一定”,意为“您一定就是 Peters 太太了”。A 选项 might 表示可能性较低,语气太弱,不符合接待场景的礼貌确认;C、D 选项在逻辑推断上不成立。
—I don’t really like James. Why did you invite him?
—Don’t worry. He come. He said he wasn’t certain what his plans were.
A. must notB. need notC. would notD. might not
看答案
✅ D. might not(情态动词表示推测)
首先关注后文关键词 wasn’t certain,这表明 James 是否出席具有不确定性。在这种不确定的推测语境下,应使用 might not 表示“可能不”,符合逻辑。must not 在此表示强烈的否定推断,语气过重;need not 表示不需要。最容易误选的是 C,would not 表示过去的意愿或确定的否定,而此处是对将来出席情况的推测,不符合语境。
We the difficulty together, but why didn’t you tell me?
A. should faceB. might faceC. could have facedD. must have faced
看答案
✅ C. could have faced(情态动词+have done)
观察后半句“why didn’t you tell me?”,可知整个语境发生在过去。此处表达的是“过去本可以做某事但实际没做”,应使用“情态动词+have done”结构。could have faced 表示“本可以共同面对(但实际上没面对)”,符合语境逻辑。A项 should face 是对现在的建议,时态不符,是学生最容易误选的干扰项。
—You needn’t take an umbrella. It isn’t going to rain.
—Well, I don’t know. It do.
A. mightB. needC. wouldD. should
看答案
✅ A. might(情态动词表示可能性)
观察对话语境,对方认为不会下雨,而说话人表示不确定,用“I don’t know”暗示一种不确定的推测。此时需用 might 表示“可能”,构成 It might do (rain) 表达对下雨可能性的保留。would 表示意愿或习惯,should 表示应当,均不符合语境。最容易误选 D,因为 should 在某些语境下可表示预期,但此处强调的是不确定的可能性,而非理应发生。
I have a word with you? It won’t take long.
A. CanB. MustC. ShallD. Should
看答案
✅ A. Can(情态动词表示请求)
观察句子结构,这是一个疑问句,后接动词原形 have,且后文 It won’t take long 表明说话者在请求对方抽出时间交谈。Can 用于请求许可或询问可能性,在此处表示“我可以和你谈谈吗?”,符合语境。Must 表示必须,Should 和 Shall 在此语境下不符合请求对方时间的习惯用法,尤其是 Shall 常用于提议或建议,而非请求许可。
—Can’t you stay a little longer?
—It’s getting late. I really go now, My daughter is home alone.
A. mayB. canC. mustD. dare
看答案
✅ C. must(情态动词辨析)
首先看上下文,对方请求留下来,但说话人提到“天晚了”且“女儿独自在家”,这构成了必须离开的客观压力。在这种强烈的必要性下,应选择表示“必须”的 must。may 表示可能,can 表示能力或许可,dare 表示敢于,均不符合语境。最容易误选 can,但此处强调的是责任和紧迫感而非能力,故排除。
I love the weekend,because I get up early on Saturdays and Sundays.
A. needn’tB. mustn’tC. wouldn’tD. shouldn’t
看答案
✅ A. needn’t(情态动词辨析)
首先分析句子逻辑,前半句提到“喜欢周末”,说明后半句应是一个正向的理由。根据语境,周末早起并非被禁止,而是没有必要,因此选择表示“不需要”的 needn’t。mustn’t 表示强烈的禁止,语气过重且不符合生活常识,故排除。注意区分“不需要”与“不准”的语义差别。
Samuel, the tallest boy in our class, easily reach the books on the top shelf.
A. mustB. shouldC. canD. need
看答案
✅ C. can(情态动词表示能力)
首先分析句子结构,主语是 Samuel,其同位语 the tallest boy in our class 提示了关键信息:他身材最高。根据逻辑,身材高的人在够高处书籍时具备某种“能力”,因此选择表示能力的 can。A 选项 must 表示必须或肯定,B 选项 should 表示应该,D 选项 need 表示需要,均不符合语境。最容易误选 A,但此处强调的是客观能力而非主观推断或强制要求。
In today’s information age, the loss of data cause serious problems for a company.
A. needB. shouldC. canD. must
看答案
✅ C. can(情态动词辨析)
句子主语是 the loss of data,谓语部分缺少情态动词。根据语境,数据丢失“有可能”给公司带来严重问题,表示一种客观的可能性,因此选 can。should 表示应当,must 表示必须,均不符合逻辑。最容易误选的是 must,因为它强调的是必然性,而数据丢失不一定会导致严重问题,can 表达的概率性更准确。
⚠️ 易错点
- 把 mustn’t 译成不必;它表示禁止,不必应为 needn’t 或 don’t have to。
- 把 could、might、would 一律当过去时;它们也可用于现在的委婉表达或假设。
- 在情态动词后加 -s 或 to,如 can goes、must to go;通常应接动词原形。
- 把 may not 与 can’t 的推测强度等同;前者可能不,后者不可能。
- 把 needn’t have done 解释成没做;该结构通常说明已经做了但无必要。
- 断定 didn’t need to do 必然没做;它只说明当时不需要,实际是否做要看语境。
- 见 should have done 就断言没做;它也可能表示按理应已完成的预期。
- 用 would 随意替代过去状态的 used to;would 表过去习惯通常写反复的动作。

12 虚拟语气先判真实与假设,再按各分句的时间选形式
📝 北京怎么考:北京卷历年单项填空考查虚拟条件句、错综时间和 wish;阅读中要辨清事实与假设,写作中可用于建议和愿望。本章收录北京卷单项填空 10 题(2010—2018 年中的 9 年)。
if 虚拟条件句三类
虚拟语气用于假设与事实相反或可能性极小的情况。
• 真实条件:If it rains tomorrow, we will stay indoors.(预测未来可能发生,不用虚拟)
• 时间判定:形式上的过去不一定表示过去时间
• 主句变化:would 可依语义换为 could(能够)或 might(可能)
• be 动词:书面语中与现在事实相反用 were,不受人称限制
| 假设时间 | if 从句 | 主句 |
|---|---|---|
| 现在 | 一般过去式;be 用 were | would/could/might + 动词原形 |
| 过去 | had + 过去分词 | would/could/might have + 过去分词 |
| 将来,可能性很小 | 一般过去式 / should + 动词原形 / were to + 动词原形 | would/could/might + 动词原形 |
| 假设参照时间 | 常见时间信号 | 判断提示 |
|---|---|---|
| 现在 | now, today, usually, every day, at present | 与现在的身份、状态或能力相反 |
| 过去 | yesterday, last week, two years ago, in 2020, then | 与已经发生的事实相反 |
| 将来 | tomorrow, next week, in the future, soon | 与将来不太可能发生的情况相反 |

错综时间条件句
从句按条件时间,主句按结果时间。
• 条件和结果时间不同,即为错综时间条件句。
• 禁止整句机械套用同一时态。
• then、yesterday 常指过去条件。
• now、today 常提示现在结果。
• 例外:需结合句意判断。
| 条件时间 | 结果时间 | if 从句 | 主句 |
|---|---|---|---|
| 过去 | 现在 | had + 过去分词 | would/could/might + 动词原形 |
| 现在 | 过去 | 一般过去式;be 用 were | would/could/might have + 过去分词 |
| 过去 | 将来 | had + 过去分词 | would/could/might + 动词原形 |
| 现在 | 将来 | 一般过去式;be 用 were | would/could/might + 动词原形 |

• 希望某人改变行为或情况变化 → would do。
• 希望有能力或可能做某事 → could do。
• if only 可独立表达愿望。

| 意思 | 常用形式 |
|---|---|
| 但愿现在…… | wish / if only + 主语 + 一般过去式;be 用 were |
| 但愿当时…… | wish / if only + 主语 + had + 过去分词 |
| 希望情况或对方有所改变 | wish / if only + 主语 + would + 动词原形 |
| 希望自己有能力做某事 | wish + 主语 + could + 动词原形 |
| 结构 | 含义 | 谓语形式 |
|---|---|---|
| wish to do | 想要做某事 | 不定式 |
| wish sb to do | 希望某人做某事 | 不定式 |
| if only | 要是……就好了 | 按愿望的时间选虚拟形式 |

• 不属实且先于当时:用 had done。
• 不属实且随后发生:用 would do。
• 例外:不能见 as if 就一律后退时态。
| 语境 | 从句形式 |
|---|---|
| 内容可能属实 | 按实际时间使用正常时态 |
| 与当时同时,内容不真实 | 一般过去式;be 用 were |

• 触发词:suggest, recommend, propose, advise, demand, request, require, order, insist
• 形式:肯定 (should) do;否定 (should) not do;被动 (should) be done
• 扩展:suggestion, proposal, request 等名词后的同位语或表语从句同理

我们的提议是修复那座旧桥。
suggest 与 insist 的语义分流
suggest/insist 引导从句:要求做某事用 (should) do,陈述事实用正常时态。
• suggest 表示“建议” → (should) do
• suggest 表示“表明,暗示” → 正常时态
• insist 表示“坚持要求” → (should) do
• insist 表示“坚持说、坚称某事实” → 正常时态
| 词语 | 从句含义 | 谓语形式 |

• 过去式:表示该做而尚未做,非叙述过去。
• should do:should 不省略。
• 例外:It is time to do / It is time for sb to do 用不定式。
| 结构 | 含义 | 谓语形式 |
|---|---|---|

would rather 的两种结构
would rather 的形式由“是否有新主语”和“时间点”决定。
• 无新主语(自己做):现在/将来用动词原形,否定用 would rather not do。
• 无新主语(自己做):回顾过去用 have done。
• 有新主语(宁愿某人做):现在/将来用过去式。
• 有新主语(宁愿某人做):过去用 had done。
| 结构 | 时间或意义 | 形式 |
|---|---|---|
| would rather do | 现在或将来更愿意做 | 动词原形 |
| would rather not do | 现在或将来不愿意做 | not + 动词原形 |
| would rather have done | 过去本愿意做或本应做 | have + 过去分词 |

我本来宁愿待在家里读那本小说。
but for 与含蓄条件
but for、without + 名词短语可表示‘要不是……’,相当于一个未写出的 if 条件;主句仍按现在或过去的假设选 would do 或 would have done。otherwise / or 有时表示‘否则’,前句陈述真实情况,后句说明未发生的假设结果。but for 和 without 也可用于真实叙述,要结合语境,不能一律认作虚拟。
| 表达 | 含义 | 主句常见形式 |
|---|---|---|
| but for + 名词/动名词 | 要不是…… | would/could/might (have) + 相应形式 |
| without + 名词短语 | 如果没有…… | would/could/might (have) + 相应形式 |
| otherwise | 否则 | would/could/might (have) + 相应形式 |
| or | 否则 | would/could/might (have) + 相应形式 |
要不是你的提醒,我就会忘记那次约定了。 Without clean water, life would be impossible.

我们坐了出租车;否则,就会错过开幕式了。 Without your help, I could not have finished the task so quickly.
没有你的帮助,我不可能这么快完成任务。
虚拟条件省略 if
虚拟语气省略 if:将 were, had, should 提前至主语前。
• Were I... = If I were...
• Had I done... = If I had done...
• Should it happen... = If it should happen...
• 否定式:not 放在主语后
• 例外:过去式实义动词不可直接前移
| 完整形式 | 省略 if 后的倒装形式 | 含义 |
|---|---|---|
| If I were you… | Were I you… | 与现在事实相反 |
| If he had finished… | Had he finished… | 与过去事实相反 |
| If it should happen… | Should it happen… | 将来情况不确定 |
| If I had not known… | Had I not known… | 过去事实相反的否定形式 |
如果当时我注意到了警告,就会立即停下来。 Were I you, I would accept the offer.
如果我是你,我会接受这份提议。 Should it happen, please call me immediately.
如果发生这种情况,请立即给我打电话。 Had I not known the answer, I would have asked you.
要是我当时不知道答案,我就会问你了。
虚拟语气的识别信号速查
1. 先看句意判断是否与事实相反、是否表达愿望、建议或假设结果。
2. 再找触发词,如 if、were、had、should、wish、if only、as if、would rather 等。
3. 随后标时间,确定现在、过去或将来参照点。
4. 最后套结构,注意 suggest、insist 等词还要根据语义分流。
5. 单个信号词不能决定形式,if、without、otherwise 等也可能用于真实语气。

|---|---|---|
| if + 一般现在/过去式 | 可能是真实条件,也可能是虚拟条件 | 主句形式和事实可能性 |
| were / had done / should do | 虚拟条件或虚拟条件倒装 | 假设的参照时间 |
| wish / if only | 与事实相反的愿望 | 现在还是过去 |
| as if / as though | 相似或假想的比较 | 内容可能真实吗 |

would、could、might 的虚拟用法
1. would、could、might 都可以出现在虚拟条件句的主句中。
2. would 通常表示假设性的结果或‘会做某事’,语气最直接。
3. could 常侧重能力、可能性或较温和的假设。
4. might 常侧重可能性,语气比 would 更不确定。
5. 与现在或将来事实相反时,三者后接动词原形。
6. 与过去事实相反时,三者后接 have + 过去分词。
7. could have done 常强调过去本有能力或机会,might have done 常强调过去本有某种可能。

2. 常见形容词有 important、necessary、essential、vital、desirable、urgent 等。
3. 从句谓语用 (should) + 动词原形,否定式用 (should) not do。
4. 从句表示被动动作时,用 (should) be + 过去分词。
5. It is important for sb to do 使用普通不定式,不属于这种 that 从句虚拟结构。
6. 这种结构表达形式上的必要性,不能因主句是过去时就改成过去式。

|---|---|---|
| 重要、必要、至关重要 | It is important/necessary/essential/vital that sb… | (should) + 动词原形 |
| 值得、紧迫 | It is desirable/urgent that sb… | (should) + 动词原形 |

📌 北京真题 10 题原卷原题,答案按官方解析;单项填空 10 题
--The weather has been very hot and dry.
--Yes. If it had rained even a drop, things would be much better now! And my vegetables .
A. wouldn't dieB. didn't dieC. hadn't diedD. wouldn't have died
看答案
✅ D. wouldn't have died(对过去的虚拟语气)
观察 If 引导的条件句使用了 had rained,表明是对过去的虚拟。主句 things would be much better now 是对现在的虚拟(混合虚拟),但紧接着的 And 连接的第二个分句 my vegetables ______ 逻辑上是指蔬菜在过去干死这件事,而非现在状态。因此应使用对过去的虚拟形式 wouldn't have died。选项 A 表达的是对现在的虚拟,不符合蔬菜已死亡的事实。
—Where are the children? The dinner’s going to be completely ruined.
—I wish they always late.
A. weren’tB. hadn’t beenC. wouldn’t beD. wouldn’t have been
看答案
✅ A. weren’t(wish引导的虚拟语气)
看到 wish 引导的从句,需判断虚拟时间。句中 always 表明说话人是对孩子们“经常迟到”这一现状或习惯性状态感到不满,属于对现在的虚拟。根据虚拟语气规则,对现在的虚拟需用一般过去时,故选择 weren’t。最容易误选 C,因为 wish + would do 通常用于表达对将来或某种可改变情况的愿望,而此处描述的是一种持续的习惯状态,应使用过去式。
Maybe if I science, and not literature then, I would be able to give you more help.
A. studiedB. would studyC. had studiedD. was studying
看答案
✅ C. had studied(对过去的虚拟语气)
观察主句谓语为 would be able to,结合语境可知是在假设一种与过去事实相反的情况。根据虚拟语气规则,对过去的虚拟,if 从句应使用过去完成时,故选 had studied。注意 then 在此处仅起承接作用,不能作为判断时态的依据。最容易误选 A,因为 studied 表示对现在的虚拟,与句中表达的“当时”这一语境不符。
Don’t handle the vase as if it made of steel.
A. isB. wereC. has beenD. had been
看答案
✅ B. were(as if 引导的虚拟语气)
看到 as if 引导的从句,需判断是对事实的描述还是虚拟假设。花瓶(vase)显然不是由钢(steel)制成的,此处为虚拟语气。根据虚拟语气规则,对现在事实的虚拟,be 动词统一用 were。因此选择 B. were。最容易误选 A. is,因为它将该句误认为是对客观事实的陈述,忽略了虚拟语气的逻辑。
If we a table earlier, we couldn’t be standing here in a queue.
A. have bookedB. bookedC. bookD. had booked
看答案
✅ D. had booked(混合虚拟语气)
看到 if 引导的条件句且主句出现 couldn't be,应考虑虚拟语气。主句表示“现在”的结果(standing here),而订桌子这个动作发生在“更早之前”(earlier),属于对过去的虚拟。因此从句需用“had + 过去分词”,故选 had booked。最容易误选 B,因为 B 是对现在的虚拟,与 earlier 矛盾。
We back in the hotel now if you didn’t lose the map.
A. areB. wereC. will beD. would be
看答案
✅ D. would be(与现在事实相反的虚拟语气)
观察句子结构,if 从句使用了一般过去时 didn’t lose,且句中出现 now,表明这是一个与现在事实相反的虚拟语气句型。根据虚拟语气公式“if + 一般过去时,主句 + would/should/could/might + 动词原形”,主句应填 would be。最容易误选的是 C,因为它将句子误认为是对未来的真实预测,忽略了虚拟语气的时态倒退规律。
IfI it with my own eyes , I wouldn’t have believed it.
A. didn’t seeB. weren’t seeingC. Wouldn’t seeD. hadn’t seen
看答案
✅ D. hadn’t seen(虚拟语气对过去的假设)
观察主句谓语 wouldn’t have believed,这是典型的“情态动词+have+过去分词”结构,表明该句是对过去事实的虚拟。根据虚拟语气时态一致原则,if 引导的条件从句应使用过去完成时,因此填入 hadn’t seen。最容易误选 A,因为 didn’t see 是对现在或将来的虚拟,与主句的时态不匹配。
Why didn’t you tell me about your trouble last week? If you me, I could have helped.
A. toldB. had toldC. were to tellD. would tell
看答案
✅ B. had told(虚拟语气(与过去事实相反))
首先看后半句,主句使用了 could have helped,这是典型的虚拟语气结构。结合前文 last week 明确时间点在过去,可知这是一个与过去事实相反的虚拟条件句。根据语法规则,if 引导的条件句应使用过去完成时,因此选 had told。很多同学容易误选 A,因为 A 是过去时,仅适用于对现在或将来情况的虚拟。
If the new safety system to use, the accident would never have happened.
A. had been putB. were putC. should be putD. would be put
看答案
✅ A. had been put(虚拟语气(对过去的虚拟))
观察主句谓语 would never have happened,由“would have done”可知是对过去的虚拟。根据虚拟语气一致性原则,if 引导的条件句应使用“had done”结构。且 safety system 与 put 之间是被动关系,需用被动语态,故选 A. had been put。B 选项 were put 是对现在的虚拟,与主句时态不匹配,容易误选。
They might have found a better hotel if they a few more kilometers.
A. droveB. would driveC. were to driveD. had driven
看答案
✅ D. had driven(虚拟语气对过去的假设)
观察句子结构,主句使用了“might have found”,这是典型的虚拟语气对过去情况的假设。根据虚拟语气时态一致原则,if 引导的条件句应使用过去完成时,因此选择 had driven。这句话表达的是:如果他们当时多开了几公里,可能就找到了更好的酒店。最容易误选 A,因为 drove 是一般过去式,不能满足过去完成时的虚拟条件,与主句的 might have found 的过去假设不匹配。
⚠️ 易错点
- 不要把虚拟形式的过去式都译成过去时间:If I were you 指现在的假设。
- 错综条件句不能主从一起后退:过去条件加现在结果应是 had done 配 would do。
- suggest 表示‘表明’、insist 表示‘坚称事实’时,不套 (should) do。
- It is time that 后的 should 通常不省略,不能误写成 It is time that we leave。
- would rather do 和 would rather sb did 是两套结构,后者不能直接接 sb do。
- if only 是‘要是……就好了’,only if 是‘只有……才’,词序改变意思也改变。
✏️ 自测 5 题
- 用括号内词完成句子:If I had brought my glasses, I ______ (would; be) able to read this sign now.
看答案
✅ would be 过去没带眼镜影响现在的阅读能力,是过去条件加现在结果。
- 表达对昨天的遗憾:I wish I ______ (not miss) yesterday’s lecture.
看答案
✅ had not missed wish 后对已经过去的事情表示遗憾,用过去完成式。
- 选词填空,insist 表示‘坚持要求’:The doctor insisted that the wound ______ (be / was / had been) cleaned at once.
看答案
✅ be insist 表示要求立即处理,省略 should 后保留被动结构中的 be。
- 填正确形式:I would rather you ______ (not tell) him the news tomorrow.
看答案
✅ did not tell would rather 后完整分句表示将来的愿望,用一般过去式。
- 用括号内词完成过去的假设:But for the map, we ______ (would; lose) our way last night.
看答案
✅ would have lost but for 暗含与过去事实相反的条件,结果用 would have done。
三、从句与连词
定语从句、名词性从句、状语从句、并列句
13 定语从句先找先行词,再看它在从句中充当什么成分
📝 北京怎么考:北京卷常考语法填空中的关系词;历年单项填空覆盖关系代词、副词及非限制性定语从句,阅读和写作也常见。本章收录北京卷单项填空 11 题(2008—2018 年中的 11 年)、语法填空 7 空(2019—2026 年中的 7 年)。
先行词与选择步骤
定语从句:找先行词 → 还原成分 → 选关系词
• 先行词:被修饰的名词或代词
• 关系词:连接从句并在其中充当成分
• 第一步:找先行词
• 第二步:将先行词放回从句,判断其作主语、宾语、定语还是状语
• 第三步:结合限制性、非限制性和介词位置选词
• 例外:不要只凭先行词的汉语意思选词
| 先行词及从句缺口 | 常见关系词 | 示例 |
|---|---|---|
| 人;从句缺主语 | who / that | the man who called me |
| 人;从句缺宾语 | whom / who / that | the man whom I called |
| 物;从句缺主语 | which / that | the book which changed my life |
| 物;从句缺宾语 | which / that | the book which I borrowed |
| 地点;缺地点状语 | where / in which | the town where we lived |
| 时间;缺时间状语 | when / on which | the day when we met |
| 原因;缺原因状语 | why / for which | the reason why he refused |
| 判断步骤 | 具体操作 | 常见误区 |
|---|---|---|
| 第一步:找先行词 | 圈出主句中被从句修饰的名词或代词 | 把从句中的普通代词误当先行词 |
| 第二步:查成分 | 把先行词放回从句,标出主语、宾语、定语或状语 | 只按汉语意思猜关系词 |
| 第三步:查限制 | 看逗号、介词位置和先行词前的限定词 | 看到地点名词就一律用 where |
| 第四步:查谓语 | 关系词作主语时核对先行词的单复数 | 关系词已作主语后又加一个主语 |
发现错误的那位科学家给我们发来了一条消息。 The message that she sent us was brief.
她发给我们的那条消息很简短。 The village where my aunt lives is near a lake.
我姑姑居住的村庄在一个湖附近。 The day when we arrived was unusually busy.
我们到达的那天异常忙碌。
关系代词的分工
关系代词根据指代对象及在从句中充当的成分(主语、宾语或定语)来选择。
• who:指人,作主语或宾语
• whom:指人,作宾语
• which:指物,作主语或宾语
• that:指人或物,作主语或宾语
• whose:指人或物,表示所属,后接名词
• 限制性从句省略规则:作宾语的可省略;例外:介词前置时不可省略
• 限制性从句省略规则:作主语的不可省略
| 关系代词 | 指代 | 在从句中的作用 | 限制性从句中能否省略 |
|---|---|---|---|
| who | 人 | 主语、宾语 | 作宾语时可 |
| whom | 人 | 宾语 | 可 |
| which | 物 | 主语、宾语 | 作宾语时可 |
| that | 人或物 | 主语、宾语 | 作宾语时可 |
| whose + 名词 | 人或物 | 表示所属 | whose 短语不能 |
| 关系词 | 可替换的人称代词 | 还原句 |
|---|---|---|
| who | he / she | He called me. |
| whom | him / her | I called him. |
| which | it | It changed my life. |
| that | he / she / it | It explains the problem. |
| whose + 名词 | 不能直接替换 | 先还原所属名词 |
给你打电话的那位女士是一名教师。 The editor whom we interviewed works nearby.
我们采访的那位编辑在附近工作。 The book which I borrowed was very useful.
我借的那本书非常有用。 The student that helped me was from Beijing.
帮助我的那名学生来自北京。 They repaired a house whose roof had been damaged.
他们修缮了一座屋顶受损的房子。
when、where、why 与代词的对比
关系副词(when/where/why)在从句中作状语,关系代词(which/that/who)作主语或宾语。
• when作时间状语,可换成适当介词 + which。
• where作地点状语,也可表示situation, case, stage等抽象情境。
• why跟在reason后作原因状语,可换成for which。
• 例外:时间、地点、原因名词后,若从句缺主语或宾语,用关系代词。
• 从句完整性看主宾成分,不能只数词。
| 关系副词 | 从句作用 | 常见改写 | 常见先行词 |
|---|---|---|---|
| when | 时间状语 | at / in / on which | time, day, year, moment |
| where | 地点状语 | in / at which | place, city, house, situation |
| why | 原因状语 | for which | reason |
| 还原后的搭配 | 从句中缺少的成分 | 关系词选择 |
|---|---|---|
| visit the town | town 作 visit 的宾语 | that / which |
| live in the town | 地点状语 | where |
| remember the day | day 作 remember 的宾语 | that / which |
| meet on the day | 时间状语 | when |
| explain the reason | reason 作 explain 的宾语 | that / which |

我们参观的那个村庄有一家小博物馆。 The day when we met was unusually busy.
我们相遇的那天异常忙碌。 I understand the reason why you refused.
我理解你拒绝的原因。
that 与 which 的选择边界
指物时 that 与 which 常可互换,但有特定边界。
• 先行词为 all, everything, nothing 等不定代词 → 优先用 that。
• 先行词被 the only, the very, 序数词, 最高级修饰 → 优先用 that。
• 先行词同时包括人和物 → 优先用 that。
• 逗号后的非限制性从句禁用 that。
• 前置介词后禁用 that。
• 注意:前三条是“优先用 that”,不是绝对禁令。
• what 不能直接跟在明确先行词后引导普通定语从句。
| 语境 | 用词倾向 | 示例 |
|---|---|---|
| 普通指物的限制性从句 | that / which | the book that I read |
| 先行词为 all、everything、nothing | that 优先 | everything that we need |
| 先行词被 the only、the very、序数词或最高级修饰 | that 优先 | the only tool that I found |
| 先行词同时包括人和物 | that 优先 | the teacher and the book that he mentioned |
| 非限制性从句 | which / who / whom / whose / when / where | My bike, which was stolen, was expensive. |
| 介词加关系词 | which / whom | the issue about which we argued |
剩下的所有东西都被装进了一个箱子。 The only tool that I could find was a hammer.
我能找到的唯一工具是一把锤子。 The report which you sent me needs revision.
你发给我的那份报告需要修改。 My bike, which was stolen last week, was expensive.
我上周被偷走的自行车很贵。
介词加 which 或 whom
介词 + which/whom 引导定语从句,关系词不可省略。
• 指物用 which,指人用 whom。
• 介词由动词搭配、形容词搭配或先行词与从句的关系决定。
• some/most/two + of which/whom 常用于非限制性从句,表示部分。
• 例外:固定短语动词(如 look after)的介词不可拆到关系词前。
| 结构 | 先行词 | 作用 | 示例 |
|---|---|---|---|
| 介词 + which | 物 | 关系词作介词宾语 | the issue about which we argued |
| 介词 + whom | 人 | 关系词作介词宾语 | the researcher to whom I wrote |
| some / most / all + of which | 物 | 表示其中一部分或全部 | some of which are still missing |
| two / several + of whom | 人 | 表示其中一部分 | two of whom were engineers |
| 常见搭配 | 常见关系结构 | 示例 |
|---|---|---|
| argue about | about which | the issue about which we argued |
| deal with | which ... deal with | the problem which we had to deal with |
| depend on | on which | the result on which the plan depends |
| apply to | to which | the rule to which all students must follow |
| be familiar with | with which | the topic with which I am familiar |
| look after | whom ... look after | the child whom we look after |

限制性与非限制性
限制性从句限定对象(无逗号),非限制性从句补充说明(有逗号)。
• 限制性:不用逗号,限定“是哪一个”。
• 非限制性:用逗号,补充已确定对象。
• 非限制性:不用 that,关系词不可省略。
• 非限制性 which:可指代前面整件事,谓语用单数。
• 关系词:who 指人,whose 表所属,when、where 引导相应补充说明。
| 对比项目 | 限制性从句 | 非限制性从句 |
|---|---|---|
| 作用 | 限定是哪一个人或物 | 补充说明已知对象 |
| 标点 | 一般不用逗号 | 一般用逗号 |
| 先行词 | 常为不确定或泛指对象 | 常为已经确定的对象 |
| 关系词 | that、which、who、whose、when、where 等 | 不能用 that |

as 引导的定语从句
as 引导定语从句可作成分(主/宾),或表示“正如”引导非限制性从句。
• such...as / the same...as:as 在从句中作主语或宾语。
• the same...that:强调同一对象;the same...as:强调同类或相似。
• 非限制性从句:表示“正如”,可放句首、句中或句末(如 as we know, as is expected)。
• 对比 which:which 指代整件事时放在其后,说明结果或评价。

| 结构或用法 | 连接词的作用 | 示例 |
|---|---|---|
| such + 名词复数 + as 从句 | as 作关系代词 | such volunteers as can work patiently |
| the same + 名词 + as 从句 | as 作关系代词 | the same materials as we used |

the way 后的三种连接
the way 引导定语从句时,根据其在从句中的成分决定连接词。
• 作方式状语:用 that / in which / 省略,不用 how。
• 作主语:用 that / which。
• 作宾语:用 that / which / 省略。
• 例外:不能见 the way 就一律套用方式状语的三种形式。
| the way 在从句中的功能 | 可用连接形式 | 能否省略 | 示例 |
|---|---|---|---|
| 方式状语 | that / in which / 无连接词 | 可以 | the way (that) he solved it |
| 宾语 | that / which | 限制性从句中可 | the way (that) we chose |
| 主语 | that / which | 不可以 | the way that surprised us |

让我们感到意外的是他的非凡耐心。
避免多出一个主语或宾语
关系词已在从句中占位,不可再用代词重复占位。
• 先划主句,再查从句主谓宾。
• 关系词与普通代词不可同时表示同一成分。
• 关系词作主语时,谓语单复数随先行词。
| 关系词的作用 | 正确结构 | 常见错误 |
|---|---|---|
| 作主语 | that explain the problem | that they explain the problem |
| 作宾语 | which I borrowed yesterday | which I borrowed it yesterday |
| 作所属定语 | whose father is a doctor | whose his father is a doctor |
| 作从句谓语的主语 | who called me | who he called me |
解释这一发现的那些文章很容易读懂。 The camera which I borrowed yesterday is waterproof.
我昨天借的那台相机是防水的。 The boy whose father is a doctor studies hard.
那个父亲是医生的男孩学习很努力。 The report that you sent me needs careful checking.
你发给我的那份报告需要认真核查。
whose 的所属表达与易混点
1. whose 表示所属,后面必须接名词,可指人也可指物。
2. whose 加名词在从句中可作主语,也可作宾语。
3. whose 可以理解为“先行词的加 the 再加该名词”,如 whose roof 等于 the house's roof。
4. whose 不能单独作主语或宾语,who 才可以单独承担这些成分。
5. 指物的所属关系也可用 of which,指人的所属关系也可用 of whom。
6. of whom 常用于 some of whom、a colleague of whom 等结构,of which 后同样通常接名词。
| 形式 | 先行词 | 含义 | 例句 |
|---|---|---|---|
| whose + 名词 | 人或物 | 直接表示所属 | the man whose car was stolen |
| of which + 名词 | 物 | 表示所属 | a house, the roof of which was damaged |
| of whom + 名词 | 人 | 表示所属 | a colleague of whom I have great respect |
| 易混点 | 正确用法 | 错误风险 |
|---|---|---|
| who 与 whose | who 单独作主语或宾语,whose 后接名词 | 把 whose 当作 who 使用 |
| which 与 whose | which 可作主语或宾语,whose 表示所属 | whose 后直接接另一个关系词 |
| whose 与 of which | 二者都可表示物的所属,whose 更直接 | 误写 whose which |
| 所属名词 | whose 后必须是名词或名词短语 | whose he、whose they |
我遇到一位女儿是医生的男子。 They repaired a house whose roof had been damaged.
他们修缮了一座屋顶受损的房子。 Have you read the book whose title appears on the list?
你读过书名出现在名单上的那本书吗? Her teacher, whose comments were very useful, helped her a lot.
她的老师给她了很多帮助,其评语非常有价值。
what 与关系代词、关系副词的区别
1. what 是复合关系代词,兼有关系代词和疑问代词的作用,前面没有先行词。
2. what 在自己的从句中作主语或宾语,意思相当于 the thing 或 things that/which。
3. what 不能跟在明确的先行词后引导普通定语从句。
4. what 从句整体还可以在主句中作主语、宾语或表语。
5. what 与 that 不同,that 在宾语从句中通常不充当主语、宾语或定语。
6. who、which、that、where、when 等通常各自承担较明确的关系或成分。
| 结构 | 有无明确先行词 | 从句中的成分 | 相当于 |
|---|---|---|---|
| what + 从句 | 没有 | 主语或宾语 | the thing(s) that/which |
| that + 从句 | 没有 | 不充当成分 | 引导宾语从句等 |
| which / that + 从句 | 有 | 主语或宾语 | 普通定语从句 |
| who + 从句 | 没有 | 主语或宾语 | the person(s) who/that |
| 结构 | 主句中的功能 | 例句 |
|---|---|---|
| what + 从句 | 主语 | What he said surprised us. |
| what + 从句 | 宾语 | I know what you mean. |
| what + 从句 | 表语 | This is what I need. |
| the thing + that/which | 名词短语 | the thing that he said |
最打动我的就是他的决心。 I don't know what you mean.
我不明白你的意思。 This is exactly what I was looking for.
这正是我在寻找的东西。 What he said at the meeting surprised everyone.
他在会上说的话让每个人都感到意外。
关系代词作主语时的主谓一致
1. 关系代词作主语时,从句谓语的单复数与先行词保持一致。
2. 先行词是单数名词或不可数名词时,从句谓语通常用单数。
3. 先行词是复数名词时,从句谓语通常用复数。
4. each、every、everyone、either、neither 等后接 who 或 that 时,从句谓语通常用单数。
5. one of the students 后接 who 或 that 时,关系词指复数 students,从句谓语通常用复数。
6. 主句谓语和从句谓语要分别判断,不能看到主句是单数就把从句也改成单数。
| 先行词 | 从句谓语形式 |
|---|---|
| a student / the teacher | 单数 |
| students / the teachers | 复数 |
| everything / anything / nothing | 单数 |
| one of the students | 复数 |
| one of the books | 复数 |
| 先行词类型 | 常见例词 | 从句谓语 |
|---|---|---|
| 不定代词 | everyone, somebody, anyone, nobody | 单数 |
| each / every | each student, every teacher | 单数 |
| either / neither | either answer, neither answer | 单数 |
| one of + 复数名词 | one of the students | 复数 |
| both / all / some + 复数名词 | all students, some books | 复数 |
学习最努力的学生往往成绩最好。 The students who study hard often help each other.
学习刻苦的学生们常常互相帮助。 One of the students who were absent yesterday is my cousin.
昨天缺席的学生中有一个是我的表弟。 Everything that remains will be sold.
剩下的一切都将被卖掉。
定语从句谓语时态与标志词速查
1. 定语从句谓语的时态由从句自身的时间参照决定,不要求与主句时态一致。
2. 表示一般特征、定义、习惯或普遍事实时,通常使用一般现在时。
3. 表示过去发生、当时正在进行、已经完成或将来发生的事件时,分别选择相应的过去、进行、完成或将来形式。
4. 时间状语是判断时态的重要线索,但同一个时间词也可能出现在不同语境中。
5. since 和 for 常提示现在完成时或现在完成进行时,具体形式取决于动作是否仍在持续或是否强调过程。
6. when、where、why 只说明时间、地点或原因关系,不能单独决定从句谓语的时态。
7. 判断时先找时间状语,再核对助动词、be 动词和动词形式。
| 时态 | 常见标志词或信号 | 从句谓语形式 |
|---|---|---|
| 一般现在时 | usually, often, every day, on Mondays, 客观事实 | do / does |
| 现在进行时 | now, at present, currently, Look!, Listen! | am / is / are doing |
| 一般过去时 | yesterday, ago, last week, in 2020, just now | do / did |
| 过去进行时 | at 8 yesterday, this time last week, when, while, all morning | was / were doing |
| 现在完成时 | since, for, already, yet, just, ever, never, so far, recently | have / has done |
| 现在完成进行时 | since, for, all day, these days, recently | have / has been doing |
| 一般将来时 | tomorrow, next week, soon, in + 一段时间, be going to, will | will do / be going to do |
| 将来进行时 | at 8 tomorrow, this time next week, when + 将来时间 | will be doing |
| 过去完成时 | by + 过去时间, before / after + 过去事件, by the time, already | had done |
| 过去完成进行时 | by + 过去时间, before / after + 过去事件, since / for + 过去参照点 | had been doing |
| 一般将来时 | tomorrow, next week, soon, in + 一段时间, be going to, will | will do / be going to do |
| 将来完成时 | by + 将来时间, before + 将来截止点, by the time | will have done |
| 将来完成进行时 | by + 将来时间, until, for + 一段时间 + 将来参照点 | will have been doing |
| 过去将来时 | by the next day, two days later, the following week | would do |
| 从句与主句的时间关系 | 常见时态选择 |
|---|---|
| 从句动作早于主句动作 | 一般过去时或过去完成时 |
| 从句动作与主句动作同时发生 | 一般过去时、一般现在时或进行时 |
| 从句动作晚于主句动作 | 一般将来时或将来完成形式 |
| 表示定义、特征或习惯 | 一般现在时 |

我们下学期将采用的方案仍在讨论中。 The man who has finished the experiment will leave soon.
已经完成实验的那个人很快就会离开。
定语从句与同位语从句的区分
1. 定语从句修饰先行词,同位语从句解释先行词的具体内容。
2. 定语从句中的关系词在从句中充当主语、宾语或定语,同位语从句中的 that 不充当这些成分。
3. 定语从句作宾语时关系词可以省略,同位语从句中的 that 通常不能省略。
4. 同位语从句通常有明确的主语和谓语,而定语从句可因关系词承担成分而缺少主语或宾语。
5. whose 通常引导定语从句,同位语从句表示所属时通常用 of。
6. 逗号可以提供判断线索,但不能只凭逗号区分,因为非限制性定语从句和同位语从句都常使用逗号。
| 对比项目 | 定语从句 | 同位语从句 |
|---|---|---|
| 作用 | 修饰或限定先行词 | 解释先行词的内容 |
| 关系词或连接词 | who, which, that, whose, when, where 等在从句中承担成分 | that 通常只连接,不承担成分 |
| 省略 | 限制性从句中作宾语的关系词可省略 | that 通常不能省略 |
| 核心判断 | 把先行词放回从句后仍有成分缺口 | that 不作成分且从句另有主语和谓语 |
| 结构 | 判断 | 原因 |
|---|---|---|
| the news that shocked us | 定语从句 | that 在 shocked 前作主语 |
| the news that he had left | 同位语从句 | that 不作成分,he 是从句主语 |
| the suggestion that we start early | 同位语从句 | that 不作成分,we 是从句主语 |
| the suggestion that we discussed | 定语从句 | that 作 discussed 的宾语 |
| the man whose son is a doctor | 定语从句 | whose 表示所属 |
帮助我的那位男士是一名教师。 The suggestion that we start early was practical.
我们早点开始的那个建议很切实可行。 The city where I grew up has changed greatly.

📌 北京真题 18 题原卷原题,答案按官方解析;单项填空 11 题;语法填空 7 空
I’ll give you y friend’s home address, I can be reached most evenings.
A. whichB. whenC. whomD. where
看答案
✅ D. where(关系副词引导定语从句)
句子由逗号隔开,此处考查非限制性定语从句。先行词是 home address(家庭住址),从句 I can be reached most evenings 结构完整,缺少的是地点状语。where 在从句中相当于 at which,表示“在那个地址”,符合语境。最容易误选 A (which),因为 which 在从句中必须充当主语或宾语,而此处从句成分已齐全,不能用 which。
–What do you think of teaching, Bob?
–I find it fun and challenging. It is a job you are doing something serious but interesting.
A. whereB. WhichC. WhenD. that
看答案
✅ A. where(关系副词引导定语从句)
观察从句结构,you are doing something serious but interesting 主谓宾完整,缺少的是状语。先行词 a job 在此处被抽象化为一种“情境”或“领域”,表示“在这个工作中”,因此用 where 引导定语从句。最容易误选 D (that),因为 that 引导的定语从句中,关系词必须在从句中充当主语或宾语,而此处从句成分已齐全,不能填关系代词。
Children who are not active or diet is high in [pic]fat will gain weight quickly.
A. whatB. whoseC. whichD. that
看答案
✅ B. whose(定语从句关系代词)
首先分析结构,Children 是先行词,who 引导第一个定语从句,or 连接第二个定语从句。观察空格后,diet 是名词且与先行词 Children 存在所属关系(孩子们的饮食),因此需填入表示“谁的”关系代词 whose 来引导从句并作定语。A 选项 what 不能引导定语从句,C 和 D 选项 which 和 that 不能表示所属关系,故排除。
Mary was much kinder to Jack than she was to the others, , of course, made all the others upset.
A. whoB. whichC. whatD. that
看答案
✅ B. which(which引导非限定性定语从句)
观察句子结构,逗号后是一个不完整的句子,缺少主语,需填入关系代词。此处指代前面整个主句的内容(即玛丽对杰克更好这件事),在非限定性定语从句中,只能用which来指代前面整个句子。因此选择which。注意that不能引导非限定性定语从句,所以不能选D。
When deeply absorbed in work, he often was,he would forget all about eating or sleeping.
A. thatB. whichC. whereD. when
看答案
✅ B. which(非限制性定语从句)
观察结构,主句是 he would forget...,中间插入了一个由逗号隔开的从句。此处 which 引导非限制性定语从句,指代前面“deeply absorbed in work”这一状态,且 which 在从句中作表语(还原为 he was deeply absorbed in work)。选 B 是因为 which 可指代前文内容。最容易误选 D,因为 when 引导时间状语从句,但此处 was 后面缺少表语,when 无法充当表语。
Many countries are now setting up national parks animals and plants can be protected.
A. whenB. whichC. whoseD. where
看答案
✅ D. where(关系副词引导定语从句)
主句为 Many countries are now setting up national parks,从句 animals and plants can be protected。分析从句结构,主谓宾完整,缺少的是地点状语。先行词 national parks 表示地点,且在从句中作地点状语,因此选 where。最容易误选 B,因为 which 是关系代词,在从句中必须充当主语或宾语,而此处从句成分已齐全,不能用 which。
I borrow the book Sherlock Holmes from the library last week, my classmates recommended to me..
A. whoB. whichC. whenD. Where
看答案
✅ B. which(定语从句引导词)
观察句子结构,主句谓语为 borrow(虽原题时态有误,但结构完整),空格后是谓语 recommended,此处需填入引导词引导定语从句。先行词是 the book Sherlock Holmes,指代物,因此必须用 which 来引导,并在从句中作 recommended 的宾语。A 选项 who 只能指代人,不能修饰书,故排除。
Opposite is St.Paul’s Church, you can hear some lovely music.
A. whichB. thatC. whenD. where
看答案
✅ D. where(关系副词引导定语从句)
首先分析句子结构,空格前是地点名词 St. Paul’s Church,后接一个完整的句子 you can hear some lovely music。由于从句中主谓宾齐全,缺少的是地点状语,相当于 in the church,因此应填入关系副词 where 来引导定语从句。最容易误选 A 选项 which,因为 which 是关系代词,在从句中必须充当主语或宾语,而此处从句成分完整,无法使用 which。
I live next door to a couple children often make a lot of noise.
A. whoseB. whyC. whereD. which
看答案
✅ A. whose(whose引导定语从句)
首先分析句子结构,主句是 I live next door to a couple,后面跟着一个定语从句修饰 a couple。观察从句 children often make a lot of noise,发现 children 与先行词 a couple 之间存在所属关系,即“这对夫妻的孩子”,因此必须用 whose 来表示所有格。故选 A。注意不要误选 which,因为 which 只能指代物且不能表示所属关系。
The little problems we meet in our daily lives may be inspirations for great inventions.
A. thatB. asC. whereD. when
看答案
✅ A. that(定语从句关系代词)
主句是 The little problems may be inspirations,空格处引导定语从句修饰 problems。观察从句 we meet in our daily lives,发现及物动词 meet 缺少宾语,因此需填入关系代词。先行词是物且在从句中作宾语,用 that 即可。容易误选 where,因为看到 lives 误以为是地点,但 where 在从句中不作成分,而此处必须填入作宾语的词。
She and her family bicycle to work, helps them keep fit.
A. whichB. whoC. asD. that
看答案
✅ A. which(非限制性定语从句)
观察句子结构,空格前有逗号,且后面跟着一个完整的句子,此处需要一个引导词来连接。which 在这里引导非限制性定语从句,指代前面整个句子“她和家人骑车上班”这件事,并在从句中作主语。that 不能引导非限制性定语从句,因此排除 D。
The students benefitting most from college are those are totally engaged(参与)in academic life.
看答案
✅ who / that(限制性定语从句主语)
先行词 those 指人,关系词在定语从句中作主语,可用 who 或 that。
When you sleep,your brain sorts through everything happened during the day,trying to link new experiences to old memories.
看答案
✅ that(everything后的定语从句)

看答案
✅ who(who引导限制性定语从句)
先行词 everybody 指人,定语从句缺主语,用 who。
⚠️ 易错点
- 先行词是地点不等于必填 where:若从句缺 visit 的宾语,应选 which/that。
- 非限制性从句不能用 that,也不能把作宾语的关系词省掉。
- 前置介词后用 which/whom,不用 that/who,也不能把关系词省略。
- whose 可修饰物,不能把 whose roof 错写成 which roof。
- 修饰表示方式的 the way 时,不写 the way how;可用 the way that / in which 或直接接从句。
- 不要写 the book which I bought it,which 已作 bought 的宾语,应删 it。

14 名词性从句(主语、宾语、表语、同位语从句)整句当名词用,位置定类别,成分和句意定连接词
📝 北京怎么考:北京卷常考语法填空的名词性从句连接词;历年单项填空涉及 what、that、whether、whoever 等,阅读需辨清从句边界,写作可用主语、宾语和表语从句。本章收录北京卷单项填空 20 题(2008—2018 年中的 11 年)、语法填空 5 空(2019—2025 年中的 5 年)。
四类名词性从句
名词性从句即“分句充当名词”,在大句中作主语、宾语、表语或同位语。
• 主语从句:作“什么……怎么样”中的“什么”。
• 宾语从句:在及物动词或介词后。
• 表语从句:在 be 等系动词后。
• 同位语从句:说明 fact, news, idea, belief 等名词的内容。
• 判断步骤:先判整个从句在大句中的作用,再判连接词在小句中的作用。
| 类别 | 外层作用 | 常见引导词 | 判断重点 |
|---|---|---|---|
| 主语从句 | 作主句主语 | that, whether, what, 疑问词 | 整个从句回答“是什么” |
| 宾语从句 | 作动词或介词的宾语 | that, whether, if, what 等 | 常由 ask、tell、know、wonder 等引出 |
| 表语从句 | 作系动词后的表语 | that, whether, what, how, why | 常见结构是 The question/problem is... |
| 同位语从句 | 解释前面名词的具体内容 | that, whether 等 | 先行词常为 fact、news、idea、hope 等 |
他的发现改变了我们的计划。 I wonder why the screen is blank.
我想知道屏幕为什么是空白的。 The question is whether the roof is safe.
问题在于屋顶是否安全。 The news that the library would reopen delighted us.
图书馆即将重新开放的消息让我们很高兴。
宾语从句
1. 宾语从句在句中作宾语,出现在三个位置:及物动词后(I know that…)、介词后(It depends on whether…)、部分形容词后(I'm sure / afraid / glad that…)。
2. 选引导词看从句缺什么:结构完整、意思是陈述事实用 that(常可省);结构完整、表示“是否”用 whether / if;缺主语、宾语、表语用 what / who / whom / which;缺状语用 when / where / why / how。
3. 一律陈述语序:引导词 + 主语 + 谓语,不把 be、助动词或情态动词提前。I wonder where he lives,不说 where does he live。
4. 时态呼应:主句是现在时或将来时,从句按实际时间选;主句是过去时,从句用相应的过去时态(一般过去、过去进行、过去完成、过去将来);客观真理、自然规律仍用一般现在时。
5. 否定前移:think、believe、suppose、expect、imagine 后的宾语从句要表达否定时,通常把 not 放在主句:I don't think he is right。反意疑问句跟从句:I don't think he is right, is he?
6. it 作形式宾语:宾语从句后面还有宾补时,用 it 占位,从句放到后面:I find it strange that he didn't come. 常见动词 find、think、make、consider、feel。
7. that 什么时候不能省:两个并列宾语从句的第二个 that;it 作形式宾语时的 that;介词后的从句不用 that 引导(except that、in that 除外)。
| 从句缺什么 / 表什么 | 引导词 | 例句 |
|---|---|---|
| 结构完整,陈述事实 | that(可省) | She said (that) she was tired. |
| 结构完整,表“是否” | whether / if | I wonder whether / if it will rain. |
| 缺主语或宾语(指物) | what / which | Tell me what you need. |
| 缺主语或宾语(指人) | who / whom | Do you know who broke the window? |
| 缺定语(谁的) | whose | I don't know whose bag this is. |
| 缺时间、地点、原因、方式状语 | when / where / why / how | Can you tell me how I can get there? |
| 主句时态 | 从句时态 | 例句 |
|---|---|---|
| 一般现在时 / 将来时 | 按实际时间选 | He says he will come tomorrow. |
| 一般过去时(从句同时发生) | 一般过去时 / 过去进行时 | He said he was busy. |
| 一般过去时(从句更早发生) | 过去完成时 | He said he had finished the work. |
| 一般过去时(从句在之后发生) | 过去将来时 | He said he would come the next day. |
| 一般过去时(客观真理) | 一般现在时 | The teacher told us the earth goes around the sun. |
| 只能用 whether 不用 if 的情况 | 例句 |
|---|---|
| 介词后 | It depends on whether we have enough time. |
| 紧接 or not | I don't know whether or not he will come. |
| 后接不定式 | I can't decide whether to go. |
| 放句首(主语从句)、表语、同位语从句 | Whether he will come is uncertain. |
你能告诉我最近的银行在哪儿吗?(陈述语序,不说 where is) I wonder whether the museum will be open on Monday.
我想知道博物馆周一是否开放。 She told me that she had already seen the film.
她告诉我她已经看过那部电影了。(主句过去时,更早的动作用过去完成时) I don't believe he will give up easily, will he?
我不相信他会轻易放弃,对吧?(否定前移,反意疑问跟从句) We think it necessary that everyone should take part.
我们认为每个人都参加是必要的。(it 作形式宾语)
that 与 what
that 只起连接作用,what 既连接又充当成分。
• that:不译,在从句内不作主语、宾语或表语。
• what:译为“……的事物/内容”,在从句内作主语、宾语或表语。
• 判断方法:检查从句动词是否缺必要成分。
• 例外:不能仅凭从句有主语和谓语就判定为完整。
| 检查点 | that | what |
|---|---|---|
| 从句内成分 | 不充当主语、宾语或表语 | 可充当主语、宾语或表语 |
| 核心意义 | 说明一个事实或观点 | 表示所说、所想或所要知道的内容 |
| 典型结构 | I know that he is honest. | I know what he wants. |
| 翻译特点 | 通常不单独翻译 | 常译为“所……的”或“什么” |
机器突然停止运转这件事让工程师担忧。 What the engineer needed was a spare part.
那位工程师需要的是一个备用零件。 I still remember what the teacher said at the meeting.
我仍然记得老师在会上说的话。 We cannot tell what caused the delay.
我们无法得知延误的原因。
whether 与 if 表是否
whether 和 if 均可表“是否”,且在宾语从句中均不充当从句成分。
• 句首主语从句、表语从句、同位语从句用 whether。
• 介词后的宾语从句用 whether。
• 直接接 or not 或 to do 用 whether。
• 动词后的宾语从句,or not 在句末时 whether/if 均可用(例外:不可因句末有 or not 就判定 if 错误)。
• whether…or… 可表示两种选择。
| 使用位置或结构 | whether | if |
|---|---|---|
| 句首主语从句 | 使用 | 不使用 |
| 表语从句 | 使用 | 不使用 |
| 同位语从句 | 使用 | 不使用 |
| 介词后的宾语从句 | 使用 | 不使用 |
| 动词后的宾语从句 | 通常使用 | 通常可以使用 |
| 直接接 or not 或 to do | 使用 | 不能直接替换 |
团队能否按时完成仍不确定。 We talked about whether the entrance should be moved.
我们讨论了是否应该移动入口。 She has not decided whether or not to join us.
她还没决定是否加入我们。 The question is whether he will come.
问题在于他是否会来。
连接代词与连接副词
连接词必须同时满足从句成分缺失(语法)和语境含义(意义)。
• who:指谁,作主语
• whom:指谁,作宾语(例外:非正式语体常以 who 代替)
• whose:表所属
• which:表“哪一个/哪些”,常有选择范围
• what:表内容
• when, where, why, how:分别表时间、地点、原因、方式或程度,作状语
• which, what, whose:还可修饰后面的名词
| 类别 | 词语 | 核心意义 | 从句中的作用 |
|---|---|---|---|
| 连接代词 | who / whom | 谁 | 主语或宾语 |
| 连接代词 | whose | 谁的 | 表示所属或限定 |
| 连接代词 | which | 哪一个、哪些 | 限定、主语或宾语 |
| 连接代词 | what | 什么内容 | 主语、宾语或表语 |
| 连接副词 | when / where / why / how | 时间、地点、原因、方式 | 状语 |
请解释这把锁是怎样运作的。 No one knew whose bag had been left on the bus.
没人知道遗留在公交车上的是谁的包。 Tell me which of these routes is shorter.
请告诉我这些路线中哪一条更短。 I wonder how the new system works.
我想知道这个新系统是如何运行的。
whoever 与 whatever
whoever/whatever/whichever 可引导名词性从句或让步状语从句。
• whoever:任何……的人
• whatever:任何……的事物/无论什么
• whichever:限定范围内无论哪一个
• 形式判定:whoever 或 whomever 由其在从句中的成分决定,而非仅看前面是否有介词
• 让步用法:表示“无论……都……”
• 例外:no matter who/what 仅引导让步状语从句,不能代替作主语或宾语的名词性从句
| 词语 | 名词性从句意义 | 让步意义 | 使用重点 |
|---|---|---|---|
| whoever | 任何……的人 | 无论谁 | 在从句中可作主语或宾语 |
| whomever | 任何……的人 | 较少单独用于让步 | 正式语体中的宾语形式 |
| whatever | 任何……的事物 | 无论什么 | 在从句中可作主语或宾语 |
| whichever | 限定范围内无论哪一个 | 无论哪一个 | 常有明确的选择范围 |
| no matter who / what | 不直接充当名词性从句 | 无论谁 / 什么 | 引导让步状语从句 |
谁第一个解出这道谜题,谁就能得到一个笔记本。 I will call whoever the principal recommends.
我会给校长推荐的人打电话。 You may take whatever you need for the experiment.
你可以取用实验所需的任何东西。 Whichever route you choose, tell me before you leave.
无论你选择哪条路线,离开前都告诉我。 Whatever happens, keep a record of the results.
无论发生什么,都要记录结果。
陈述语序与时态
名词性从句必须用陈述语序(主+谓),禁止助动词提前。
• 连接词作主语时,直接接谓语。
• 主句过去时 → 从句相应使用过去时。例外:客观真理用一般现在时。
• 主句现在时 → 从句按实际时间选择时态。
| 外层句情况 | 从句常用时态 | 说明 |
|---|---|---|
| 主句为现在时或将来时 | 按实际时间选择 | 不强制改为一般现在时 |
| 主句为一般过去时 | 通常用相应过去时态 | 按语境作必要调整 |
| 主句为过去时,内容是客观真理 | 一般现在时 | 如 The teacher explained that light travels fast. |
| 过去发生的更早动作 | 过去完成时 | 常见 after、by then 等语境 |
| 过去语境中的未来安排 | 过去将来时 | 常用 would do |
| 时态 | 谓语结构 | 常见标志词或信号 |
|---|---|---|
| 一般现在时 | do / does + 动词原形 | every day, usually, often, always, never, on Sundays |
| 一般过去时 | did + 动词原形 / 动词过去式 | yesterday, last night, last week, ... ago, in 2020, just now |
| 现在进行时 | am / is / are + doing | now, at the moment, right now, currently, Look!, Listen!, these days |
| 过去进行时 | was / were + doing | at 8 last night, this time yesterday, when / while + 过去事件 |
| 一般将来时 | will + do / be going to do / be about to do | tomorrow, next week, next month, soon, in the future, before..., by... |
| 过去将来时(一般过去将来时) | would + do / was going to do | the next day, two days later, by then, at that time |
| 现在完成时 | have / has + 过去分词 | since, for, so far, up to now, recently, lately, already, yet, ever / never |
| 过去完成时 | had + 过去分词 | by the end of last..., before..., by then, when / after + 过去事件 |
| 现在完成进行时 | have / has been + doing | for the last..., since..., all morning, how long |
| 过去完成进行时 | had been + doing | for + 一段时间 + 另一个过去事件之前, all... earlier |
| 直接疑问句 | 嵌入后的名词性从句 |
|---|---|
| Where is the meeting room? | Could you tell me where the meeting room is? |
| Who broke the window? | She asked who had broken the window. |
| Did he agree? | I wonder whether he agreed. |
| How does it work? | Please explain how it works. |
| What caused the delay? | We do not know what caused the delay. |
你能告诉我会议室在哪里吗? She asked who had opened the window.
她问是谁打开了窗户。 The teacher explained that water expands when it freezes.
老师解释说水结冰时会膨胀。 I did not know whether he would arrive the next day.
我不知道他第二天是否会到。 I wonder whether the report has been submitted.
我想知道这份报告是否已经提交。
it 作形式主语或宾语
用 it 占位,将长从句后移。
• 形式主语:It is clear/a pity/reported that...(主语从句后移)
• 形式宾语:find it strange that...(带宾补的长宾语从句后移)
• 性质:it 不代指具体物品,仅为占位符
• 例外:It is necessary that... 等必要、建议类结构可用 (should) do
| 功能 | 常用结构 | 例句 | 说明 |
|---|---|---|---|
| 形式主语 | It is + 形容词 + that + 从句 | It is clear that the samples are different. | that 从句是真正主语 |
| 形式主语 | It is + 名词 + that + 从句 | It is a pity that we missed the bus. | it 无具体指代 |
| 形式宾语 | find / think / make + it + 形容词 + that + 从句 | We found it strange that nobody answered. | it 占住宾语位置 |
| 固定报道结构 | It is reported that + 从句 | It is reported that the plant will close. | 真正主语为 that 从句 |
显然,这两个样本不同。 We found it surprising that no one had checked the date.
我们觉得令人意外的是,竟然没人核对过日期。 It is reported that the museum will open next month.
据报道,博物馆将于下月开放。 I consider it necessary that we check the data again.
我认为我们有必要再次核对数据。
同位语从句与定语从句
同位语从句解释“具体内容”,定语从句限定“是哪一个”。
• 同位语从句:that只连接,不作成分。
• 定语从句:关系词在从句中作成分。
• 同位语从句常见于fact, news, idea, hope, belief, possibility之后。
• 同位语从句可用whether, why引导。
• 例外:不能仅凭“名词后有that”认定类别。
| 比较项目 | 同位语从句 | 定语从句 |
|---|---|---|
| 先行词 | 常为 fact、news、idea、hope 等抽象名词 | 常为人、物、地点或具体事物 |
| 从句作用 | 解释先行词的具体内容 | 限定或说明“哪一个”先行词 |
| 连接词 | that、whether、why、how 等 | who、whom、whose、which、that 等 |
| 成分检查 | that 不作主语、宾语或表语 | 关系词通常在从句中承担成分 |
| 典型结构 | The fact that he was late surprised us. | The fact that the inspector reported shocked the mayor. |
桥梁不安全这一事实导致它被封闭。 The fact that the inspector reported shocked the mayor.
检查员报告的那个事实让市长感到震惊。 There is some doubt whether the material can be recycled.
这种材料能否回收利用还存在疑问。 The news that the library would reopen delighted us.
图书馆即将重新开放的消息让我们很高兴。
that 的省略与原因句型
宾语从句 that 可省,其余名词性从句 that 保留。
• 单个普通动词宾语从句:that 可省
• 句首主语从句、表语从句、同位语从句:that 保留
• it 形式主语后的从句:that 保留
• 并列宾语从句:后一个从句的 that 保留
• The reason is that...:that 后接原因内容
• That is why...:后接结果
• That is because...:后接原因
• 例外:不要写成 The reason is because...
| 结构 | that 的使用 | 示例 |
|---|---|---|
| 单个普通动词的宾语从句 | 常可省略 | I believe (that) the plan is useful. |
| 句首主语从句 | 通常保留 | That he was right surprised us. |
| 表语从句或同位语从句 | 通常保留 | The reason is that the road is closed. |
| it 形式主语后的从句 | 通常保留 | It is clear that he was right. |
| 并列宾语从句 | 后一个从句通常保留 | I think that he is right and that we should act. |
他说他已经完成了工作。 The reason for the delay is that the road is closed.
延误的原因是道路被封闭了。 The road is closed. That is why the bus is late.
道路被封闭了,这就是公交车晚点的原因。 I believe the plan is useful and that it will save time.
我相信这个计划有用,而且它会节约时间。
介词后的宾语从句
- 介词后接名词性从句时,从句作介词的宾语,仍要使用陈述语序。
- 介词后表示“是否”用 whether,不能用 if 代替 whether。
- 介词后询问“具体什么内容”通常用 what,如 be aware of what...。
- 介词后不能用 that 引导表示“是否”的宾语从句。
- 介词与从句构成完整的介词短语,修饰前面的名词、动词或形容词。
| 常见提示结构 | 从句连接词 | 表达意义 |
|---|---|---|
| be aware of whether... | whether | 意识到是否…… |
| depend on whether... | whether | 取决于是否…… |
| be based on what... | what | 以什么为依据 |
| talk about what... | what | 谈论什么内容 |
| regardless of whether... | whether | 不管是否…… |
我们讨论了是否应该移动入口。 Her success depended on what she had prepared.
她的成功取决于她事先准备的内容。 He was unaware of what was happening around him.
他没有意识到周围正在发生什么。 The decision was based on whether the results were reliable.
这个决定取决于结果是否可靠。
whether...or not 与 if...to do
- whether...or not表示“是否”,or not 可以放在从句主语之前,也可以放在从句末尾。
- whether + to do表示“是否做某事”,在 decide、know、wonder 等结构中不能把 whether 直接换成 if。
- if 可以引导动词后的宾语从句表示“是否”,但 if 从句中的 or not 只能放在句末。
- 宾语从句中的 if...or not 可以使用,但高考书面表达中通常优先使用 whether...or not。
- if + to do 若表示“如果要做某事”,则是条件状语从句,不属于名词性从句。
| 结构 | whether | if | 说明 |
|---|---|---|---|
| whether + 从句 + or not | 可以 | 不能直接替换 | or not 可置于从句首或末 |
| whether + to do | 可以 | 不能直接替换 | 表示是否做某事 |
| whether / if + 一般从句 | 可以 | 可以 | 通常限于动词后的宾语从句 |
| if + 从句 + or not | 优先使用 | 有时可用 | or not 放在从句末尾 |
这个计划是否可行仍不确定。 We must decide whether to move the meeting.
我们必须决定是否推迟会议。 Could you tell me whether the lab is open?
你能告诉我实验室是否开放吗? I don't know if the lab is open or not.
我不知道实验室是否开放。
what 从句与定语从句转换
- what 从句可理解为 the thing(s) that...或 the thing(s) which...,表示未具体说明的内容。
- 作主语的 what 从句可转换为 The thing that...或 Everything that...引导的主语从句。
- 作宾语的 what 从句可转换为 know the thing that...、remember the words that...等结构。
- that 单独不能代替 what,因为 that 只起连接作用,不能把所指内容带进从句。
- which 通常用于已知或可选择的范围,强调“哪一个”;what 强调未具体说明的“什么东西或内容”。
| what 从句 | 转换形式 | 转换说明 |
|---|---|---|
| What he needs | The thing(s) that he needs | what = the thing(s) that |
| What she said | The thing that she said / Everything that she said | 可按语境选择单数或复数 |
| What matters most | The thing that matters most | what 在从句中作主语 |
| This is what I meant | This is the thing that I meant | what 从句作表语 |
他需要的是一个备用零件。 What she said surprised everyone.
她所说的话让每个人都很吃惊。 What matters most is not speed but accuracy.
最重要的不是速度而是准确。 This is exactly what I meant.
这正是我的意思。
名词性从句常见搭配一览

名词性从句易混点速查
- 从句缺主语、宾语或表语时,在 what、who、whom、which、whatever、whoever 中选择。
- 从句结构完整而表示“是否”时,在 that、whether、if 中选择,并检查所在位置。
- that 表示已知事实或陈述内容,what 表示未具体说明的内容,which 表示“哪一个”。
- 已知范围内“无论哪一个”用 whichever,泛指“任何事物”用 whatever。
- 问原因用 why 或 because,问时间、地点和方式分别用 when、where 和 how。
- 介词后问“是否”用 whether,问“什么内容”用 what。
- no matter who、no matter what 等表示“无论”,引导的是让步状语从句,不是名词性从句。
| 题面线索 | 优先考虑 | 关键理由 |
|---|---|---|
| 从句缺主语、宾语或表语 | what, who, whom, which, whatever, whoever | 连接词要在从句中充当成分 |
| 从句完整,表达一个事实 | that | that 不作成分且通常不译出 |
| 从句完整,问是否 | whether / if | if 受句首、表语、同位语和介词后等位置限制 |
| 问哪个 | which / what | which 有选择范围,what 表示具体内容 |
| 已知范围内无论哪个 | whichever | whichever of... |
| 任何事物或任何人 | whatever / whoever | 也可在让步句中表示“无论” |
| 时间、地点、原因、方式 | when, where, why, how | 在从句中作状语 |
| 介词后问是否或内容 | whether / what | 介词后不用 if |

The companies are working together to create they hope will be the best means of transport in the 21st century.
A. whichB. thatC. whatD. who
看答案
✅ C. what(what引导宾语从句)
观察句子结构,create 后面缺少宾语,且空格前没有先行词,说明此处需填入引导词引导名词性从句。在从句中,will be 缺少主语,因此需要 what 既在从句中作主语,又在整体结构中充当 create 的宾语(hope 为插入语)。最容易误选的是 which 或 that,因为它们引导定语从句必须有先行词,而此处无先行词可修饰。
At first he hated the new job but decided to give himself a few months to see it got any better.
A. whenB. howC. whyD. if
看答案
✅ D. if(宾语从句引导词)
首先分析句子结构,see 后面接的是宾语从句。根据语境,他给自己几个月时间是为了观察工作情况“是否”会好转,表示一种不确定的假设,因此应选 if 引导宾语从句,意为“是否”。注意 if 在此处等同于 whether。很多同学容易误选 how,但 how 强调“如何”好转,而此处逻辑重点在于好转与否的结果。
I want to be liked and loved for I am inside.
A. whoB. whereC. whatD. how
看答案
✅ C. what(名词性从句作介词宾语)
首先分析结构,介词 for 后面接的是一个名词性从句作介词的宾语。这里考查 what 引导的从句,what I am 是固定表达,指代一个人的本质、性格或品质,意为“我的为人”或“内在特质”,符合 inside 的语境,因此选 C。很多同学误选 A,是因为习惯性认为指代“人”必须用 who,但 who I am 侧重于身份(如姓名、职业),而非内在品质。
Part of the reason Charles Dickens loved his own novel, David Copperfield, was it was rather closely modeled on his own life.
A. whatB. thatC. whyD. whether
看答案
✅ B. that(表语从句)
首先分析句子结构,主语是 Part of the reason,系动词是 was,空格后引导的是表语从句。观察从句 it was rather closely modeled on his own life,成分完整,不缺主语或宾语,因此需要一个起连接作用但不充当成分的引导词,选 that。最容易误选的是 what,因为它在从句中必须充当主语或宾语,而此处从句结构完整,无法使用。
some people regard as a drawback is seen as a plus by many others.
A. WhetherB. WhatC. ThatD. How
看答案
✅ B. What(主语从句引导词)
首先分析句子结构,主句谓语是 is seen,空格起引导作用,构成主语从句。观察从句 some people regard as a drawback,regard A as B 结构中缺少宾语 A,因此需要一个既能引导从句又能充当宾语的词,What 正好符合要求,意为“……的事物”。最容易误选 That,因为它在引导主语从句时不做成分,而此处从句成分不完整,不能用 That。
Barbara Jones offers to her fans is honesty and happiness.
A. WhichB. WhatC. ThatD. Whom
看答案
✅ B. What(主语从句引导词)
首先分析句子结构,主句谓语是 is,空格起首的部分是主语从句。观察从句内部,offer 是及物动词,后面缺少宾语,因此需要一个既能引导从句又能充当宾语的词,选择 What。What 在此处相当于 the thing that。最容易误选 That,因为 That 引导名词性从句时在从句中不担任任何成分,而此处从句缺宾语,故不能选 That。
The shocking news made me realize terrible problems we would face.
A. whatB. howC. thatD. why
看答案
✅ B. how(宾语从句引导词辨析)
realize 后面接宾语从句。从句是 we would face ___ terrible problems,空格修饰形容词 terrible,表示“多么严重的问题”,这是感叹意味的程度,用 how + 形容词 + 名词复数,故选 B. how。A. what 修饰的是名词(what problems“什么问题”),不能直接修饰形容词 terrible 来强调程度;C. that 在宾语从句里不作成分,后面不能缺东西;D. why 问原因,不合句意。
Jerry did not regret giving the comment but felt he could have expressed it differently.
A. whyB. howC. thatD. whether
看答案
✅ C. that(宾语从句引导词)
句子主干是 Jerry did not regret... but felt...,felt 后接从句作宾语。从句 he could have expressed it differently 结构完整,表达的是一个具体的事实,因此选用 that 引导宾语从句,that 在句中不充当成分。容易误选 B (how),因为 how 强调“如何”的方式,而此处语境是表达一种意识到某事的心理状态,而非探讨具体如何表达。
makes the book so extraordinary is the creative imagination of the writer.
A. ThatB. WhatC. WhoD. Which
看答案
✅ B. What(主语从句引导词)
观察句子结构,主句谓语是 is,空格起首的部分是主语从句。从句中缺少主语,且需要一个词来指代“……的事物”,因此选 What 引导主语从句,意为“……的东西/事情”。That 虽然也能引导主语从句,但此处若选 That,则其仅作为指示代词指代前文某事,而本句并无前文可指,且语义不通,无法表达“使书非凡的东西”这一含义。
Experts believe people can waste less food by shopping only when it is necessary.
A. whyB. whereC. thatD. what
看答案
✅ C. that(宾语从句引导词)
先看句子结构,Experts 是主语,believe 是谓语,后面缺少宾语,空格处引导一个从句。从句中 people can waste less food... 结构完整,不缺成分,因此需要一个起连接作用且不充当成分的引导词,选 that。what 必须在从句中担任主语或宾语,而此处从句成分齐全,故 what 错误。
The best moment for the football star was he scored the winning goal.
A. whereB. whenC. howD. why
看答案
✅ B. when(连接代词引导表语从句)
句子主语是 The best moment,系动词是 was,空格后引导一个完整的句子,构成表语从句。由于先行词 moment 表示时间,需要用 when 来引导从句,在从句中作时间状语,表示“……的时候”。故选 when。容易误选 where,因为学生常将“地点/场合”与“时间点”混淆,但此处明确指代时刻,不能用 where。
Some people believe has happened before or is happening now will repeat itself in the future.
A. whateverB. wheneverC. whereeverD. however
看答案
✅ A. whatever(复合关系代词引导主语从句)
先看句子结构,believe 后接宾语从句,而宾语从句中 repeat itself 之前缺少主语,说明空格处需引导一个名词性从句作主语。whatever 在此处相当于 anything that,既引导从句又在从句中作主语,指代“无论什么”,符合句意。注意 however 是副词,不能在从句中充当主语,因此排除。
I truly believe beauty comes from within.
A. thatB. whereC. whatD. why
看答案
✅ A. that(宾语从句连接词)
观察句子结构,believe 是及物动词,后面缺少宾语,因此空格处引导一个宾语从句。分析从句 beauty comes from within,主语、谓语、状语成分齐全,不缺任何成分,只需填入一个起连接作用且无实际意义的词,故选 that。很多同学容易误选 what,因为习惯性认为 believe 后面接 what,但 what 在从句中必须充当主语或宾语,而此处从句成分已完整,不能再加 what。
we understand things has a lot to do with what we feel.
A. WhereB. HowC. WhyD. When
看答案
✅ B. How(主语从句引导词)
首先分析句子结构,has a lot to do with 是谓语部分,空格起首的成分是主语从句。根据语境,理解事物的“方式”与感受相关,因此选择 How 引导主语从句,表示“我们如何理解事物”。最容易误选的是 Why,虽然逻辑上勉强通顺,但 How 强调的是认知过程与感受的关联,更符合语境且为地道表达。
Your support is important to our work. You can do helps.
A. HoweverB. WhoeverC. WhateverD. Wherever
看答案
✅ C. Whatever(复合关系代词引导主语从句)
观察句子结构,空格后是“You can do”且缺少宾语,而整个句子缺少主语,说明空格处需填入一个能引导主语从句且在从句中作宾语的词。Whatever 意为“无论什么”,在此引导主语从句,作 do 的宾语,全句意为“无论你能提供什么帮助都有用”。Whoever 指人,不能作 help 的修饰成分,故排除。
The most pleasant thing of the rainy season is one can be entirely free from dust.
A. whatB. thatC. whetherD. why
看答案
✅ B. that(表语从句)
观察句子结构,系动词 is 之后缺少表语,且后面是一个完整的句子,说明此处考查表语从句。从句 one can be entirely free from dust 结构完整,不缺主语、谓语或宾语,因此只需填入起连接作用且不充当成分的 that。注意区分 what,若使用 what,其含义相当于 the thing that,会导致主句的 the most pleasant thing 与从句意义重复,不符合逻辑,故排除 A。
Every year, makes the most beautiful kite will win a prize in the Kite Festival.
A. whateverB. whoeverC. whomeverD. whichever
看答案
✅ B. whoever(whoever 引导主语从句)
首先分析句子结构,主句谓语是 win,而空格引导的部分 ______ makes the most beautiful kite 整体充当主语。此处需要一个代词引导主语从句,且在从句中作主语,指代“任何……的人”,因此选择 whoever。注意 whoever 等于 anyone who。容易误选的 whichever 指代的是“任何一个(事物)”,而此处语境是做风筝的人,应指人而非物。
Jane moved aimlessly down the tree-lined street, not knowing she was heading.
A. whyB. whereC. howD. when
看答案
✅ B. where(宾语从句引导词)
句子主干是 Jane moved...,not knowing 引导的分词短语中,knowing 后接宾语从句。根据从句谓语 head(朝...方向走)的语义需求,此处需要一个表示地点的引导词,因此选择 where。why 引导原因,how 引导方式,when 引导时间,均不符合“朝某个方向走”的逻辑。最容易误选 A,因为学生常将“不知道为什么”作为习惯表达,但忽略了 head 这一动词的方位属性。
Without his support, we wouldn’t be we are now.
A. howB. whenC. whereD. why
看答案
✅ C. where(表语从句)
句子主干是 we wouldn’t be...,空格处引导一个从句作表语。根据语境,这句话是在讨论由于对方的支持,我们才达到了现在的地位或境地,where 在此引导表语从句,表示“所处的状态或地位”。因此选 where。最容易误选的 how 虽可表示状态,但通常用于描述方式或程度,而表达“现在的成就/处境”时,习惯用 where we are。
This is my father has taught me—to always face difficulties and hope for the best.
A. howB. whichC. thatD. what
看答案
✅ D. what(宾语从句引导词)
观察句子结构,be 动词 is 后面缺少表语,此处应填入一个名词性从句。从句中 taught 是及物动词,缺少宾语,且前面没有先行词。what 在从句中既充当引导词又担任 taught 的宾语,意为“……的事物”,符合句意。注意 that 不能选,因为 that 在名词性从句中不充当成分,而此处从句缺宾语。
What students do at college seems to matter much more than they go.
看答案
✅ where(比较从句中的 where)
than 后的比较从句缺地点状语,用 where 表示“去哪里/哪所大学”。

看答案
✅ if / whether(whether/if引导宾语从句)
ask 后宾语从句成分完整且表“是否”,用 if 或 whether。
The poor woman wasn't able to give him any information about she lived.
看答案
✅ where(地点宾语从句)
about 后接宾语从句,where 在从句中作地点状语。
It’s easy to explain how we determine smells are dangerous or not: we learn.
看答案
✅ whether(whether与or not搭配)
whether 与 or not 呼应,引导宾语从句。
The truth, though, is could be guessed — there’s never anyone else here.
看答案
✅ what(what引导表语从句)
表语从句中缺少主语,用 what 表示“所能猜到的事情”。
⚠️ 易错点
- 不能只见从句有主语和谓语就填 that,及物动词后缺宾语时仍可能用 what。
- 不要把宾语从句写成 where is the station,应改为 where the station is。
- 句首的‘是否’主语从句和介词后的‘是否’从句用 whether,不用 if。
- whoever 在自己的从句中作主语时不改为 whomever,即使整个从句位于介词后。
- 不要用 no matter what 直接替换作宾语的 whatever 从句;前者用于让步。
- 名词后有 that 未必是同位语从句,应检查 that 在从句中是否充当成分。
- 形式主语 it 后的 that 通常保留,避免把从句误写成另一个独立句。

15 状语从句先辨两句的逻辑关系,再选连词和时态
📝 北京怎么考:北京卷历年单项填空考时间、条件、让步、目的等关系;语法填空和阅读常涉及从句连接、时态及省略,写作要避免重复连词。本章收录北京卷单项填空 15 题(2008—2018 年中的 11 年)。
状语从句的九类关系
状语从句用分句补充主句的时间、条件、原因、目的、结果、让步、比较、方式或地点。
• 先读意思,再判关系,不要靠中文词硬配连词。
• 例外:同一个连词可有多种意思(如 as 可表时间、原因或方式;while 可表时间、让步或对比)。
| 关系 | 核心问题 | 常用连接词 | 典型信号 |
|---|---|---|---|
| 时间 | 什么时候或在什么期间 | when, while, as, before, after, until, since, once | before, during, as soon as, until |
| 条件 | 在什么条件下 | if, unless, as long as, provided/providing that | if, unless, provided that |
| 原因 | 为什么 | because, since, as, now that | because, for this reason, now that |
| 目的 | 为了什么或以防什么 | so that, in order that, in case | so that, in order to, in case |
| 结果 | 产生了什么结果 | so…that, such…that | so…, such… |
| 让步 | 尽管什么 | although, though, even though, even if | although, even if, despite |
| 比较 | 与什么相比 | than, as…as, not so/as…as | than, as…as |
| 方式 | 怎样或仿佛怎样 | as, as if/though | as, as if |
| 地点 | 在哪里 | where, wherever | where, wherever |
| 快速判断问题 | 典型答案 | 首选关系 |
|---|---|---|
| 这件事在什么时间发生? | when, while, before, until | 时间 |
| 满足什么条件才会发生? | if, unless | 条件 |
| 为什么会出现这个结果? | because, since, as | 原因 |
| 采取这一做法是为了什么? | so that, in order that | 目的 |
| 这一情况造成了什么结果? | so…that, such…that | 结果 |

虽然任务很难,团队还是按时完成了。
when、while 与 as 表时间
when/while/as 均表时间,区别在于动作的性质与状态。
• when:指时间点或时间段,动作可短暂也可持续。
• while:指“在……期间”,连用持续性动作或状态。
• as:强调动作同时进行或伴随变化,意为“一边……一边……”或“随着……”。
• 例外:be doing…when… / be about to do…when… 中,when 表示“这时突然”,后接短暂事件,不可换成 while。
| 连接词 | 核心侧重 | 常见动作关系 | 典型时间状语 |
|---|---|---|---|
| when | 时间点或一段时间 | 短动作落在某个时间点或背景中 | one day, at the moment, last Sunday |
| while | 某段持续期间 | 背景动作与另一动作同时存在 | during, all the time, the whole morning |
| as | 同时发生或伴随发展 | 过程、变化或两个动作并行 | as time went by, as the city grew |
| 结构 | 形式 | 例句骨架 |
|---|---|---|
| when + 从句 | When + 从句主语 + 谓语 | When the bell rang, … |
| while + 从句 | While + 从句主语 + 谓语 | while she was cooking, … |
| as + 从句/Doing | As + 从句主语 + 谓语 / as + doing | as the city grew / as time passed |
| be doing…when… | 主句 + be doing when + 短暂事件 | I was leaving when he called |

随着城市的发展,建起了更多公园。 I was about to leave when the phone rang.
我正要离开,这时电话响了。
until 与 not until
until 区分:肯定句表“持续到终点”,not until 表“过了起点才发生”。
• 肯定句:until = 一直到……为止,主句为可持续动作或状态。
• 否定句:not...until = 直到……才……,强调动作在指定时间前没有发生,主句为短暂动作。
• 替换:till 可替换 until。
• 位置:句首更常用 until。
• 例外:选词需综合肯定/否定与实际语义,不能只根据动词长短决定。
| 结构 | 基本含义 | 从句或主句的常见特征 | 例句骨架 |
|---|---|---|---|
| until + 从句 | 一直持续到……为止 | 主句常为持续性动作或状态 | waited until the rain stopped |
| not…until + 从句 | 直到……才…… | 主句常为句中后发生的一次性动作 | did not open until the check was complete |
| by the time + 从句 | 到……的时候已经…… | 主从句按实际先后采用相应时态 | By the time he arrived, … |
| till + 从句 | 直到…… | 用法大体同 until | We waited till dawn. |
| 比较项 | until | before |
|---|---|---|
| 关注点 | 持续到某个终点 | 发生在某个时间之前 |
| 典型改写 | continue until… | happen before… |
| 例句 | We stayed until midnight. | We left before midnight. |

图书馆一直开放到午夜。 Not until sunset did the temperature begin to fall.
直到日落,气温才开始下降。
before、since 与 once
辨析 before, since, once 的时间逻辑与时态搭配。
• before:译为“在……之前”或“还没来得及……就……”或“过了……才……”。
• It was + 一段时间 + before…:表示过了多久才发生。
• It will be + 一段时间 + before…:表示还要多久才发生。
• since:主句用完成时,从句用一般过去时交代起点。
• once:译为“一旦”,强调条件或时间节点一经达到,后续情况随之成立;不等于“曾经”。
| 连接词 | 时间关系 | 语义重点 | 常见时态提示 | 典型信号 |
|---|---|---|---|---|
| before | 某事件发生之前 | 先后顺序 | 过去或将来时按语境 | several days before, just before |
| since | 从过去某点延续到现在 | 起点和持续 | 主句现在完成时 | since then, ever since |
| once | 某一时刻或条件一达到 | 紧接着发生 | 将来时常从句用一般现在时 | once, immediately once |

油漆一干,你就可以把椅子搬回去。
条件连词与 unless
条件连词引导状语从句,核心在于区分“如果”与“只要”的逻辑。
• if:如果
• unless:除非 / 如果不
• as long as / so long as:只要
• provided / providing (that):如果 / 只要
• unless = if...not(仅限意思相符时)
• unless 后不加 not
• 例外:主句是否定时,需重新核对逻辑
| 连接词 | 基本含义 | 常见逻辑 | 例句骨架 |
|---|---|---|---|
| if | 如果 | 条件成立,结果才成立 | If it rains, we will stay indoors. |
| unless | 除非,如果不 | 常相当于 if…not | Unless you hurry, you will be late. |
| as long as / so long as | 只要 | 条件持续有效 | as long as you agree |
| provided/providing that | 如果、只要 | 提出成立条件 | provided that the weather is fine |
| on condition that | 以……为条件 | 强调条件必须满足 | on condition that you return the key |

时间条件从句的将来表达
主将从现:时间/条件状语从句用一般现在时表将来,主句用will、情态动词或祈使句。
• 强调先完成用现在完成时。
• 例外:when表“何时”、if表“是否”的宾语从句,按实际时间用will。
• 例外:will表达意愿时可用。
| 从句情形 | 从句常用时态 | 主句常用形式 | 例句骨架 |
|---|---|---|---|
| 将来时间或条件 | 一般现在时 | will / 情态动词 / 祈使句 | If it rains tomorrow, we will wait. |
| 将来先完成 | 现在完成时 | 一般将来时 | When everyone has arrived, we will begin. |
| 过去事实 | 一般过去时 | 一般过去时或过去完成时 | When he arrived, the class had begun. |
| 过去或现在假设 | 一般过去时 | would / could / might | If I were you, I would take the early train. |
| 宾语从句中的 when/if | 按实际时间 | 按宾语从句需要 | I do not know when he will arrive. |
| 判断步骤 | 问题 | 处理 |
|---|---|---|
| 第一步 | when 是“当……时”还是“何时”? | 先确定从句功能 |
| 第二步 | if 是“如果”还是“是否”? | 排除宾语从句例外 |
| 第三步 | 主句动作是否在从句之后? | 采用主将从现 |
| 第四步 | 从句动作是否先完成? | 从句考虑现在完成时 |

• 比较两边必须是同类对象(如:我的工作 vs 我原先预想的工作情况)。
• 方式从句用 as 表示“按照……的方式”。
• 方式从句用 as if / as though 表示“仿佛”。

地点从句与定语从句的边界
判断 where 引导的是状语从句(交代地点)还是定语从句(修饰名词)。
• where 引导地点状语从句:表示“在……的地方”,直接修饰主句动作,前面不需要地点名词。
• wherever 引导地点状语从句:表示“无论在什么地方”。
• where 引导定语从句:前面有被修饰的地点名词。
| 结构 | 句子功能 | 是否有先行地点名词 | 例句 |
|---|---|---|---|
| 动词 + where + 从句 | 地点状语从句 | 通常没有 | Leave the tools where you found them. |
| 地点名词 + where + 从句 | 关系从句 | 有 | This is the corner where we found them. |

状语从句常用时态与标志词速查
- 先找参照点:先确定动作发生的时间参照、动作是否完成以及是否持续,再使用标志词验证。
- 标志词不是公式:标志词只能提供线索,不能脱离上下文单独决定时态。
- 主将从现:时间或条件状语从句表示将来时,从句用一般现在时,主句用将来形式。
- 完成关系:already、yet、so far、since、for、by 等词常提示完成时或完成进行时。
- 过去参照:过去完成时、过去完成进行时和过去将来时都要先找到过去的参照点。
- 本表范围:本表覆盖高中阶段常考的十二种主干时态,每种均列出结构、标志词和典型语境。
| 时态 | 常见结构 | 高频标志词或信号 | 典型语境 |

明天这个时候,我们正在等待结果。
主从句时态呼应
- 相对时间:从句时态应根据主句动作发生前、发生时或发生后进行选择。
- 将来时间条件:从句用一般现在时,主句用一般将来时、情态动词或祈使句。
- since 搭配:since 从句用一般过去时交代起点,主句通常用现在完成时。
- 更早完成:过去某事件之前已完成的事件常用过去完成时。
- 假设语气:if 从句表示与过去事实相反时用一般过去时,主句常用 would/could 加动词原形。
- 避免机械对应:同一类从句在不同时间参照中可能需要不同时态,不能只背一个固定公式。
| 触发结构 | 从句时态 | 主句时态 | 例句骨架 |
|---|---|---|---|
| if/when + 将来 | 一般现在时 | 一般将来时、情态动词或祈使句 | If it rains tomorrow, we will stay. |

|---|---|---|
| A 发生在 B 之前 | A 已完成,B 随后发生 | A 用过去完成时,B 用一般过去时 |
| A 发生在 B 之中 | A 是背景,B 是插入事件 | A 用过去进行时,B 用一般过去时 |
| A 发生在 B 之前 | A 应当到将来完成 | A 用一般现在时,B 用将来完成时 |

状语从句常见易混连接词
- 先辨逻辑:连接词的选择取决于时间、原因、条件、让步、目的或结果关系,而不是单个中文词。
- when / while / as:when 常指出时间点或时间段,while 常铺开持续背景,as 常表示同时或伴随发展。
- since / because / as:since 可指时间起点或已知原因,because 表示直接原因,as 表原因时语气较弱。

- 比较结构:no sooner…than 和 hardly…when 都可表示“刚……就……”,但后半部分不同。
- 时态配合:固定结构中的两个分句仍要按实际时间选择时态。
- 平行结构:rather than 后可接名词、动名词或与前项结构平行的动词形式。
- 书写完整:搭配题最容易漏掉 than、when 或主句谓语。

状语从句的语序、插入与倒装
- 句首位置:状语从句置于主句前时,通常用逗号与主句隔开。
- 句末位置:状语从句置于主句后时,通常不在从句后另加逗号。
- 句中插入:when、if 等短从句可插在主语和谓语之间,通常不用逗号。
- 部分倒装:Not until、Only when、Only after、Hardly、Scarcely、No sooner 等置于句首时,主句要部分倒装。
- 固定倒装:Hardly…when 和 No sooner…than 中,前半部分常使用过去完成时并倒装。
- 倒装条件:只有这些具有否定或限定意义的短语置于句首时,才需要相应倒装。
| 位置或结构 | 语序特点 | 标点或倒装 | 例句 |
|---|---|---|---|
| 句首 | 从句 + 主句 | 从句后通常用逗号 | When he arrived, we started. |
| 句末 | 主句 + 从句 | 从句后通常不加逗号 | We started when he arrived. |
| 句中插入 | 主语 + 从句 + 谓语 | 通常不用逗号 | I will call you as soon as I arrive. |
| Not until 倒装 | Not until + 从句 + 助动词 + 主语 | 主句部分倒装 | Not until he came did we leave. |
| Only when 倒装 | Only when + 从句 + 助动词 + 主语 | 主句部分倒装 | Only when he came did we leave. |

| 从句在句末 | 通常不加逗号 | We should check the room before we leave. |
| 从句插在主谓之间 | 通常不加逗号 | We should, if possible, check the room. |
| 从句作补充说明 | 可使用逗号分开 | We should check the room, which is next to the office. |
铃响时,大家停止了交谈。 Everyone stopped talking when the bell rang.
铃响时,大家停止了交谈。 I will call you as soon as I arrive.

状语从句与名词性从句、同位语从句的辨析
- 状语从句:在句中作时间、原因、条件等状语,修饰主句的动词或整个主句。
- 名词性从句:在句中作主语、宾语或表语,其本身不能再充当主句的状语。
- 同位语从句:跟在抽象名词后,解释该名词的具体内容,如 the fact that…、the idea that…。
- 先行词判断:where、when、why 等引导关系从句时通常有先行词;作状语从句时通常直接修饰主句。
- that 与 what:what 相当于 the thing(s) which,可在名词性从句中作主语或宾语;that 不能在名词性从句中充当主语。
- if 与 whether:在宾语从句中多数情况下可互换,但表示“是否或不然”、用于介词后时通常只能用 whether。
- 整体功能:同一个连词在不同句子中可能引导不同类型的从句,必须分析整句结构。
| 从句类型 | 在主句中的作用 | 核心判断方法 | 典型结构 |
|---|---|---|---|
| 状语从句 | 时间、条件、原因等状语 | 可改写为相应的副词性短语 | Leave it where you found it. |
| 名词性从句 | 主语、宾语或表语 | 整个从句充当一个名词成分 | Tell me where you found it. |
| 同位语从句 | 解释前面的抽象名词 | that 从句说明 fact、idea、hope 等的内容 | The fact that he left surprised us. |
| 关系从句 | 修饰前面的先行名词 | 从句中缺少宾语时常用 which 或 that | the village where we lived |
| 句子 | 从句功能 | 判断依据 |
|---|---|---|
| Leave the tools where you found them. | 地点状语从句 | 直接说明动作发生的地点 |
| Tell me where you found the tools. | 宾语从句 | where 从句是 tell 的直接宾语 |
| This is where we found the tools. | 地点状语从句 | where 从句说明主句地点 |
| The village where we found the tools is small. | 关系从句 | where 从句修饰 village |
| The fact that we found the tools surprised us. | 同位语从句 | that 从句解释 fact 的内容 |
告诉我你在哪里找到钥匙的。 Leave the tools where you found them.
把工具放回你发现它们的地方。 The fact that he had resigned surprised us.
他已经辞职这一事实让我们感到吃惊。 The village where we spent our childhood is beautiful.
我们度过童年的那个村庄很美。 I wonder whether the meeting will be put off.
我想知道会议是否会延期。
📌 北京真题 15 题原卷原题,答案按官方解析;单项填空 15 题
—Did you return Fred’s call?
—I didn’t need to I’ll see him tomorrow.
A. thoughB. unlessC. whenD. because
看答案
✅ D. because(原因状语从句)
首先分析对话逻辑,第一句询问是否回电,第二句回答不需要回电,并给出理由“明天会见到他”。此处需要填入一个引导原因状语从句的连词,因此选择 because。因为“明天见面”解释了“不需要回电”的原因,逻辑通顺。最容易误选的是 though,它引导让步状语从句,表示“尽管”,与此处因果逻辑相悖。
I’m sorry you’ve been waiting so long, but it’ll still be some time Brian get back.
A. beforeB. sinceC. tillD. after
看答案
✅ A. before(before 引导时间状语从句)
句中 it'll still be some time 为主句,空格后是从句。这里考查固定句型“It will be + 时间段 + before...”,意为“在……之前还需要一段时间”,即“要过多久才……”。根据语境,Brian 回来之前还需要一段时间,故选 before。很多同学容易误选 since,但 since 通常与现在完成时连用,且表示“自从……以来”,不符合此处对未来的预测。
You may use the room as you like you clean it up afterwards.
A. so far asB. so long asC. in caseD. even if
看答案
✅ B. so long as(条件状语从句连词)
句子由主句和由连词引导的从句组成,主句表示允许使用房间,从句表示前提条件。根据语境,只要满足“事后打扫干净”这个条件,就可以随意使用,因此选择表示“只要”的 so long as。注意 A 选项 so far as 通常用于 so far as I know(据我所知),侧重范围而非条件,不能在此处替换。
they decide which college to go to, students should research the admission procedures.
A. AsB. WhileC. UntilD. Once
看答案
✅ D. Once(时间状语从句连词辨析)
首先分析句子结构,主句是 students should research...,空格处引导一个时间状语从句。根据逻辑,学生必须先决定大学,然后才能研究入学手续,这种“先...后...”的先后顺序,最适合用 Once 表示“一旦...就...”。While 强调两件事同时进行,与此处逻辑不符,因此排除。最容易误选的是 Until,它表示“直到...才”,若选 C 则意为“直到决定大学前都要研究手续”,逻辑不通。
volleyball is her main focus, she’s also great at basketball.
A. SinceB. OnceC. UnlessD. While
看答案
✅ D. While(让步状语从句)
观察句子结构,前后两个分句分别描述她“主攻排球”和“擅长篮球”,逻辑上构成对比或让步关系。While 在此处引导让步状语从句,意为“虽然/尽管”,能完美连接这两个事实。Since 表示原因或时间,Once 表示一旦,Unless 表示除非,均无法体现这种对比逻辑。学生最容易误选 Since,因为它常引导原因状语从句,但带入后语义不通。
—Look at those clouds!
—Don’t worry. it rains, we’ll still have a great time.
A. Even ifB. As thoughC. In caseD. If only
看答案
✅ A. Even if(让步状语从句)
观察对话语境,第一句提到云层厚,暗示可能下雨,第二句用 Don’t worry 安抚对方,说明无论是否下雨,结果(玩得开心)都不会改变。Even if 引导让步状语从句,表示“即使”,符合逻辑。In case 表示“以防”,强调预防措施,与后文“依然玩得开心”不符,故排除。
I took my driving license with me on holiday, I wanted to hire a car.
A. in caseB. even ifC. ever sinceD. if only
看答案
✅ A. in case(in case 引导状语从句)
句子由两个分句组成,前句是“带驾照”,后句是“想租车”,两者之间存在预防目的关系。选择 in case,意为“以防/万一”,表示为了应对可能发生的情况而提前做准备,符合语境。注意 if only 表示“但愿”,通常用于虚拟语气,与此处表达实际准备行为的逻辑不符。
the forest park is far away, a lot of tourists visit it every year.
A. AsB. WhenC. Even thoughD. In case
看答案
✅ C. Even though(让步状语从句)
句子由两个分句组成,前半句说森林公园很远,后半句说每年有大量游客访问,前后语义构成转折/对比关系。因此需要填入表示“尽管”的连词 Even though 来引导让步状语从句。As 在引导状语从句时通常表示原因或时间,不能表达这种强烈的对比含义,故排除 A。
You won’t find paper cutting difficult you keep practicing it.
A. even thoughB. as long asC. as ifD. ever since
看答案
✅ B. as long as(条件状语从句连词)
首先分析句子结构,主句是“你不会觉得剪纸难”,从句是“你坚持练习”,两者之间存在明显的条件关系。选择 as long as,意为“只要”,引导条件状语从句,逻辑通顺:只要坚持练习,就不会觉得难。最容易误选 A 选项 even though,它引导让步状语从句,意为“尽管”,会导致句意变成“尽管你坚持练习,你也不会觉得难”,逻辑不成立。
the damage is dose , it will take many years for the farmland to recover.
A. UntilB. UnlessC. OnceD. Although
看答案
✅ C. Once(状语从句连词辨析)
首先分析句子结构,空格处引导一个从句,主句表达的是土地恢复需要很多年。根据逻辑关系,前句是后句的前提,即“一旦损害造成,后果将长期存在”,因此选择 Once 引导时间状语从句,表示“一旦……就”。最容易误选的是 Unless,它表示“除非”,代入后语义变为“除非损害造成,否则需要很多年恢复”,逻辑完全相反,不符合常理。
My grandfather still plays tennis now and then, he’s in his nineties.
A. as long asB. as ifC. even thoughD. in case
看答案
✅ C. even though(让步状语从句)
句子由两个分句组成,前半句说爷爷偶尔还打网球,后半句提到他已九十多岁。两句之间存在明显的转折/让步关系,因此选择 even though 表示“尽管”。as long as 引导条件状语从句,as if 表示“仿佛”,in case 表示“以防”,均不符合逻辑。最容易误选 A,但 as long as 要求前后是条件关系而非对比关系。
I really enjoy listening to music it helps me relax and takes my mind away from other cares of the day.
A. becauseB. beforeC. unlessD. until
看答案
✅ A. because(原因状语从句)
首先分析句子结构,主句是“我喜欢听音乐”,后面跟着一个由连词引导的从句,描述听音乐带来的好处。因为“放松”和“忘记烦恼”正是喜欢听音乐的原因,前后构成明显的因果关系,所以选 because。注意区分 unless,它表示“除非”,引导条件状语从句,放入句中逻辑不通,无法解释为什么喜欢听音乐。
birds use their feathers for flight, some of their feathers are for other purposes.
A. OnceB. IfC. AlthoughD. Because
看答案
✅ C. Although(让步状语从句)
句子由两个分句组成,主句是 some of their feathers are for other purposes(部分羽毛用于其他目的),从句是 birds use their feathers for flight(鸟类用羽毛飞行)。两者之间存在转折/让步关系,即“虽然用于飞行,但也有其他用途”,因此选 Although。注意 Because 表示因果,逻辑不通,最容易误选 Once,因为它表示“一旦”,强调时间先后或条件,不符合此处对比语义。
If you don’t understand something, you may research, study, and talk to other people you figure it out.
A. becauseB. thoughC. untilD. since
看答案
✅ C. until(时间状语从句)
首先分析句子结构,主句是“你可能会研究、学习和探讨”,后面接一个由连词引导的从句。根据语境,研究和探讨这些行为是为了达到“弄明白”这个结果,因此需要一个表示时间终点的连词,选 until 表示“直到……为止”。因为 until 能够逻辑通顺地连接“持续动作”与“结束状态”。容易误选 because,因为它表示因果关系,会导致逻辑变成“因为弄明白了才去研究”,与常识相反。
we don’t stop climate change, many animals and plants in the world will be gone.
A. AlthoughB. WhileC. IfD. Until
看答案
✅ C. If(条件状语从句)
观察句子结构,主句为 will be gone,预示结果;从句 we don’t stop climate change 描述前提条件。两者之间存在明显的因果逻辑,即“如果不停止气候变化,动植物将消失”,因此选择 If 引导条件状语从句。Although 和 While 引导让步状语从句,表示转折,与句意不符;Until 表示“直到...才”,逻辑不通。
⚠️ 易错点
- 表示同一因果关系时,不写 Because…, so…;常规让步句也不写 Although…, but…。
- 不要把所有 when 都按主将从现处理:I wonder when he will arrive 中 when 引导宾语从句。
- unless 已有‘除非/如果不’的意思,不要再加一个造成逻辑反转的 not。
- in case 表预防性准备,不等于 if 表示的条件成立后才采取行动。
- not until 表‘直到……才’,不能漏掉 not 后仍按同样意思翻译。
- so many / so little 表数量时用 so,不能机械套‘名词前都用 such’。
- whatever 作主语或宾语引导名词性从句时,不能换成 no matter what。
- while 引导时间从句时常接持续动作,不能把表示‘这时突然’的 when 随意换成 while。

16 并列句与连词连接先看逻辑,再分连词与副词,检查结构和标点
📝 北京怎么考:北京卷历年单项填空考并列连词及祈使句结构,完形填空考上下文逻辑,语法填空可能涉及连接词;写作要避免逗号直接拼接两个完整句。本章收录北京卷单项填空 6 题(2009—2017 年中的 6 年)。
并列结构与并列句
并列连词连接地位相同的词、短语或分句。
• 连接两个各有主谓、可独立成句的分句 → 并列句
• 只有一个共同主语,后接两个谓语 → 并列谓语(非独立句)
• 连接多个项目:通常只在最后一项前加 and/or,必要时用逗号分隔
• 平行结构:功能相同,动词形式通常相呼应
| 结构类型 | 基本形式 | 判断方法 |
|---|---|---|
| 并列词或短语 | kind, quiet and warm | 连接成分地位相同,词性一致 |
| 并列谓语 | He opened the door and checked the corridor. | 一个主语带两个谓语 |
| 并列句 | He opened the door, and his partner checked the corridor. | 两个分句各有主语和谓语 |
| 三项并列 | observing, taking notes and discussing findings | 并列成分形式和功能呼应 |
学生们测量了池塘并记录了结果。 The students measured the pond, and their teacher checked the results.
学生们测量了池塘,老师核查了结果。 The course involves observing insects, taking notes and discussing findings.
这门课包括观察昆虫、做笔记和讨论发现。 The guide was kind, but the driver was impatient.
导游很友善,但司机很不耐烦。
and 的添加与顺承
and 用于连接并列信息,表示“和/并且”、先后顺承或结果。
• 译为“然后”时仍用 and。
• both...and... 连接成分需对应。
• 连接两个不同主语时,谓语用复数。
• 例外:连接项表示同一个人或一个整体时,按意义判断主谓一致。
| 语境关系 | and 表达的意义 | 例句 |
|---|---|---|
| 信息追加 | 和、并且、还 | She is a singer and also a dancer. |
| 动作顺承 | 接着、然后 | He checked the ticket and entered the hall. |
| 因果结果 | 结果、于是 | He ignored the warning and hurt himself. |
| 主语情况 | 谓语处理 | 说明 |
|---|---|---|
| 两个不同主语 | 通常用复数 | The guide and the driver are ready. |
| 两个部分指同一人 | 通常用单数 | The writer and teacher is our guest. |
| 一个主语带两个谓语 | 两个谓语共用主语 | He smiled and said nothing. |
我们装好了食物并检查了设备。 He unlocked the cabinet and took out a folder.
他打开柜子,取出了一个文件夹。 He ignored the warning and hurt himself.
他没有注意警告,结果弄伤了自己。 Both the guide and the driver were familiar with the route.
导游和司机都熟悉这条路线。
but、yet 与 while 对比
but, yet, while 均可表示转折或对比,但侧重与用法有别。
• but:表转折。
• yet:表“然而/却”,强调出乎预料,可用 and yet。
• while:表对比,意为“而/却”,比较两人或两事的不同。
• while:可引导时间、让步从句,按语义区分,不可见 while 就译成“当……时”。
• although/though 后通常不再用 but,但主句可用 yet。
| 词 | 核心意义 | 常见侧重点 | 例句 |
|---|---|---|---|
| but | 然而 | 直接陈述前后转折 | It was small but comfortable. |
| yet | 然而、却 | 结果出乎预料 | The plan was simple, yet it failed. |
| while | 而、却 | 两个对象形成对照 | She likes tennis, while her brother likes swimming. |
| however | 然而 | 连接副词,需配合句号、分号或插入逗号 | It was small; however, it was comfortable. |
| 常见搭配 | 使用规则 | 例句 |
|---|---|---|
| although/though, but | 保留 although/though,删除 but | Although it was small, it was comfortable. |
| but/yet, however | but/yet 可连接分句,however 通常不能单独用逗号连接两个完整句 | The task was hard, yet we finished it. |
房间虽小,却有充足的自然光。 The instructions were simple, yet several people misunderstood them.
说明很简单,然而几个人还是理解错了。 I prefer working alone, while my sister enjoys working in a team.
我更喜欢独立工作,而我姐姐喜欢团队合作。 Although the task was difficult, we finished it on time.
尽管任务很难,我们还是按时完成了。
She
had an Unpleasant voice and a direct way of speaking, 36 she was
encouraging and inspiring.
句中通过 "...way of speaking, but she was..." 体现了转折逻辑。结构上,由并列连词 but 连接两个独立分句,将前半句对声音和说话方式的负面评价与后半句对人格特质的正面评价进行对比,形成强烈的反差。全句意为:她的声音不悦耳,说话方式很直接,但她却能给人以鼓励和启发。
or 的选择与否则
or 既可表示“或者”连接选项,也可表示“否则”连接后果。
• 选项:连接备选项,表示“或者”。
• 后果:连接不采取前一行动的结果,表示“否则”。
• 否定句:连接被一并否定的两项;例外:需辨清否定范围,不可见 not 就将 and 改为 or。
• either...or...:两者择一;连接主语时,谓语与较近主语一致。
| 结构或意义 | 逻辑关系 | 例句 |
|---|---|---|
| A or B | 二选一 | Would you like tea or coffee? |
| 祈使句 + or + 陈述句 | 否则 | Save the file, or you may lose it. |
| not A or B | A、B都不选或都不成立 | I don't like tea or coffee. |
| either A or B | 在A和B中选择一个 | Either the bus or the subway is suitable. |
| 连接对象 | 谓语一致 | 示例 |
|---|---|---|
| either/or 连接两个主语 | 通常与较近主语一致 | Either the students or the teacher is ready. |
| not A or B 连接两个主语 | 通常使用复数 | Neither he nor his friends were late. |
| 一个主语带 or 连接两个谓语 | 通常使用单数 | You can call or write. |
你想现在还是午饭后讨论这个计划? Keep the receipt, or you may not get a refund.
留好收据,否则你可能无法退款。 Either the students or their teacher is responsible for the display.
要么学生们,要么他们的老师负责布置展览。 Hurry up, or you will miss the last bus.
快点,否则你会错过末班车。
so 表结果与 for 表理由
so 表结果(前因后果),for 表理由(前果后因)。
• so:前面是原因,后面是结果。
• for:后面补充理由或判断依据,常在句后且前有逗号。
• for ≠ because:because 可直接回答 why,可置于句首;并列连词 for 不这样用。
• 例外:同一因果关系中,不写 because…so…。
| 连词 | 逻辑方向 | 常见位置 | 例句 |
|---|---|---|---|
| so | 原因 → 结果 | 连接两个完整分句 | It was raining, so we stayed indoors. |
| for | 判断 → 理由或依据 | 通常放在前项之后,前有逗号 | Someone must be inside, for the lights are on. |
| because | 直接说明原因 | 句首或句中 | We stayed indoors because it was raining. |
| since/as | 补充已知理由 | 句首或句中 | Since it was raining, we stayed indoors. |
| 表达目的 | 宜用形式 | 说明 |
|---|---|---|
| 说明直接原因 | because | 可回答 why |
| 给出支持判断的证据 | for | 常用逗号加 for 引出 |
| 表达结果 | so/therefore | so 可连接分句,therefore 是连接副词 |
电梯坏了,所以我们走了楼梯。 Someone must be inside, for the lights are on.
里面一定有人,因为灯亮着。 He checked the answer twice, so he was sure it was correct.
他检查了两次答案,所以确信它是正确的。 The children were wet, for they had been playing in the rain.
孩子们浑身湿透,因为他们一直在雨里玩。
祈使句加 and 或 or
祈使句 + and/or + 陈述句,表示“条件 → 结果”。
• 祈使句 + and → 做了前面,就会有后面结果。
• 祈使句 + or/otherwise → 做前面,否则会有后果。
• 祈使句谓语用动词原形。
• 后句常用 will 或其他情态形式,但不必全部用 will。
• 例外:名词短语 + and + 陈述句(如 Another minute, and...),省去了前面的命令或条件。

成对连词与就近一致
成对连词连接成分需对称,连接主语时谓语与就近主语一致。
• not only…but also…:不仅……而且……
• either…or…:或者……或者……
• neither…nor…:既不……也不……
• not only 放句首引出分句:该分句部分倒装;but also 后分句不倒装。
• 例外:not only 仅修饰主语时不倒装。
| 结构 | 基本意义 | 连接成分要求 | 连接主语时谓语 |
|---|---|---|---|
| both A and B | A和B两者都 | A、B形式和功能对应 | 通常用复数 |
| either A or B | A或B二者之一 | A、B形式和功能对应 | 通常与较近主语一致 |
| neither A nor B | A和B两者都不 | A、B形式和功能对应 | 通常用复数 |
| not only A but also B | 不仅A而且B | A、B形式和功能对应 | 通常与较近主语一致 |
| not A but B | 不A而是B | A、B属于同类内容 | 按整体句意判断 |
| not only 的位置 | 是否倒装 | 示例 |
|---|---|---|
| 只修饰主语 | 不倒装 | Not only the students but also the teacher were present. |
| 位于分句开头并强调分句 | 分句部分倒装 | Not only did he collect the data, but he also designed the experiment. |
老师和学生们对结果都不满意。 The activity is not only enjoyable but also educational.
这项活动不仅有趣,而且有教育意义。 Not only did he collect the data, but he also designed the experiment.
他不仅收集了数据,而且还设计了实验。 Either the camera or the notebook is on the desk.
照相机或笔记本有一个在桌上。 Both the guide and the driver are familiar with the route.
导游和司机都熟悉这条路线。
however 与 therefore 的词性和标点
however 和 therefore 是连接副词,不能仅用逗号连接两个独立句。
• 逻辑:however 表“然而”,therefore 表“因此”。
• 结构1:用句号分开两句。
• 结构2:用分号连接,后接副词,再加逗号。
• 结构3:放在分句中间作插入成分。
• 例外:however + 形容词/副词引导“无论多么……”,属于让步状语从句。
| 表达 | 词性和作用 | 常见位置或标点 | 例句 |
|---|---|---|---|
| however | 连接副词,表转折 | 句号或分号后;句中用插入逗号 | The plan failed; however, the team learned a lot. |
| therefore | 连接副词,表结果 | 句号或分号后;句中用插入逗号 | The data were incomplete; therefore, we repeated the survey. |
| however + 形容词/副词 | 引导让步意义 | However hard…, we… | However hard the task is, we will finish it. |
| 标点组织方式 | 判断 | 例句 |
|---|---|---|
| 完整句 + 句号 + However, 完整句 | 规范 | The evidence was limited. However, the team continued. |
| 完整句 + 分号 + however, 完整句 | 规范 | The evidence was limited; however, the team continued. |
| 完整句 + 逗号 + however, 完整句 | 不规范 | The evidence was limited, however, the team continued. |
证据有限;然而,团队仍继续调查。 The data were incomplete. Therefore, we repeated the survey.
数据不完整。因此,我们重新做了调查。 The team, however, continued its investigation.
不过,团队仍继续调查。 However hard the task is, we will finish it on time.
无论任务多么艰难,我们都会按时完成。
instead、otherwise 与替代逻辑
instead 和 otherwise 是副词,不能当成并列连词使用。
• instead:表示“反而/代替前面方案”,提示前一做法未被采用。
• instead of:介词短语,后接名词、代词或动名词等。
• otherwise (1):表示“否则”,后句预测实际后果用 will/may,假设未发生结果用 would 或 would have done。
• otherwise (2):表示“在其他方面”。
| 词或结构 | 核心意义 | 后接成分 | 例句 |
|---|---|---|---|
| instead | 改用另一方案、反而 | 句子、名词短语或动作 | We shared a link instead. |
| instead of | 没有做前项,而做了后项 | 名词、代词或动名词 | Instead of buying jars, we reused old ones. |
| otherwise | 否则、在其他方面 | 从句或短语 | Save the file; otherwise, you will lose it. |
| otherwise + would | 否则就会…… | 主句 | If we had left earlier, we would have caught the train; otherwise, we would have missed it. |
我们没有印传单,而是分享了一个链接。 Instead of buying new jars, we reused the old ones.

连词题的检查顺序
连词题核心:先定结构,再判逻辑,后查细节。
• 找主谓:先找出空格前后各自的主谓结构。
• 判关系:判断是递进、转折、选择还是因果。
• 查细节:检查词性、平行结构、否定范围和标点。
• 避陷阱:不凭肯定/否定猜 and/or,不凭 happy/sad 等词判转折,看整段语境。
• 改病句:两完整句须用连词、分号或句号组织,例外:不能只换逻辑副词而忽略结构。
| 检查层面 | 核心问题 | 常见错误 |
|---|---|---|
| 句子切分 | 两侧能否各自组成完整句 | 把一个分句误当成独立句 |
| 逻辑关系 | 前后究竟是什么关系 | 只看到 happy、sad 等词就判断转折 |
| 词性与位置 | 该词能连接什么成分 | 用 therefore 直接连接两个完整句 |
| 主谓一致 | 最近的主语是单数还是复数 | either/or 后仍机械使用复数 |
| 平行结构 | 并列成分形式是否一致 | to do 与 doing 随意混搭 |
| 标点 | 分句之间使用什么标点 | 两个完整句之间只使用逗号 |
| 逻辑关系 | 常见候选词 | 语境提示 |
|---|---|---|
| 添加 | and, also, moreover, besides | 两者可以同时成立 |
| 转折 | but, yet, while, however | 前后意思相反或存在明显反差 |
| 因果 | so, because, since, for | 一端说明原因,另一端说明结果或依据 |
| 选择或条件 | or, either...or, unless | 存在备选项或“不做就……”关系 |
时间表变了,但没人通知来访者。 The timetable changed; therefore, we sent everyone a new copy.
时间表变了;因此,我们给每个人发了一份新版。 The road was icy, so we drove slowly.
道路结冰,所以我们慢慢开车。 You can take the bus or ride your bike.
你可以乘公共汽车,也可以骑自行车。
并列连词与从属连词辨析
1. 并列连词可以连接两个地位相同、各有主语和谓语的独立分句,常见的有 and、but、or、so、yet 和 for。
2. 从属连词引导的分句虽然也有主语和谓语,但不能独立充当完整句,必须依附于主句。
3. because、although、if、when、unless、since 和 as 通常引导从属分句,不能直接连接两个独立句。
4. so that 引导目的或结果状语从句,such that 引导结果从句,二者都不是并列连词。
5. who、which 和 that 可引导定语从句,从句在句中充当主语、宾语或表语等成分。
6. when、where 和 why 也可引导定语从句,不能只凭这些词判断它们一定表示时间或地点。
7. 同一意思常可改写为并列结构或从属结构,但改写后必须保持原来的基本逻辑关系。
| 连接词 | 能否直接连接两个独立分句 | 常见后接成分 | 主要作用 |
|---|---|---|---|
| and/but/or/so/yet/for | 可以 | 独立分句 | 并列关系 |
| because/although/if/when/unless/since/as | 不可以 | 从属分句 | 原因、让步、条件、时间等 |
| so that/such that | 不可以 | 从句 | 目的或结果 |
| who/which/that | 不可以 | 定语从句 | 修饰或指代前面的名词 |
| when/where/why | 不可以 | 定语从句或状语从句 | 时间、地点、原因或修饰名词 |
| 并列表达 | 从属改写 | 保留的关系 |
|---|---|---|
| We arrived late, and the meeting had already begun. | The meeting had already begun because we arrived late. | 因果 |
| The task was difficult, but we finished it. | Although the task was difficult, we finished it. | 让步转折 |
| Take the bus, or you will be late. | If you do not take the bus, you will be late. | 条件 |
我们迟到了,会议已经开始。 Although we arrived late, the meeting had already begun.
尽管我们迟到了,会议还是已经开始了。 Because we arrived late, the meeting had already begun.
因为我们迟到了,会议已经开始了。 The teacher showed us a map, which helped us find the route.
老师给我们看了一张地图,这张地图帮助我们找到了路线。
although、though 与 because、since 的逻辑选择
1. although和though表示让步,承认一个事实后说明主句与该事实形成反差。
2. because 表示直接原因,通常可以回答 why。
3. since 表示理由时往往基于双方已知或容易理解的情况,语体比 because 稍正式。
4. since 还可表示时间起点或持续时间,看到 since 时要结合时间语境判断。
5. as 表示理由时语气通常弱于 because,也常用于双方都清楚的原因。
6. although 或 though 引导让步状语从句后通常不再使用 but,但主句可以使用 yet。
7. because、since 和 as 引导的原因从句可以位于句首或句中,位置变化通常不改变基本逻辑。
| 连词 | 逻辑关系 | 常见语境 | 主要注意点 |
|---|---|---|---|
| although/though | 让步 | 承认事实后说明反差 | 后接陈述事实,不用虚拟语气 |
| because | 直接原因 | 回答为什么 | 原因最明确 |
| since | 已知理由或时间 | 根据已知情况说明原因 | 需排除时间含义 |
| as | 较弱理由、时间或比较 | 说明双方都明白的原因 | 需结合上下文确定功能 |
| 表达意图 | 优先选择 | 理由 |
|---|---|---|
| 直接回答 why | because | 原因与结果关系最直接 |
| 根据已知情况作判断 | since | 前提通常是说话双方已知的信息 |
| 说明双方都明白的原因 | as | 理由语气相对委婉 |
| 表达事实让步 | although/though | 前后存在反差 |
尽管他很累,但他仍继续工作。 He stayed at home because he had a fever.
他因为发烧待在家。 Since the roads were icy, we drove slowly.
由于道路结冰,我们慢慢开车。 As the roads were icy, we drove slowly.
因为道路结冰,我们慢慢地开车。
if、when、unless、until、as、since 的时间条件选择
1. if引导条件状语从句,表示“如果、假如”,可表示现实条件或假设条件。
2. unless表示“如果……不、除非”,通常可改写为 if not 加肯定形式。
3. when表示时间点或时间背景,通常不表示“如果”的假设。
4. as可表示随着时间推移,常与表示时间变化的动词搭配。
5. until表示动作持续到某个时间点或某事件发生为止。
6. since表示时间起点,也可表示从过去持续到现在。
7. before和after分别表示某时间点之前和之后,while常表示一段时间持续的过程。
8. 判断这些词时,要把从句意义放回整句,确认是时间、条件还是原因。
| 连词 | 核心意义 | 常见搭配 | 例句 |
|---|---|---|---|
| if | 如果 | if + 一般现在时 | If it rains, we will stay indoors. |
| unless | 如果不、除非 | unless + 肯定形式 | Unless you leave now, you will be late. |
| when | 当……时 | when + 过去时或现在时 | When the bell rang, the students entered. |
| as | 随着 | as + 时间变化 | As the evening came, the village became quieter. |
| until | 直到 | wait/remain until | We waited until the rain stopped. |
| since | 自从、从……起 | since + 时间点 | She has lived here since 2020. |
| before/after | 在……之前/之后 | before/after + 时间点 | We arrived before the meeting began. |
| 易混项目 | 主要差别 | 例句 |
|---|---|---|
| if 与 when | if 表示条件或假设,when 表示时间 | If it rains, we will wait. |
| as 与 when | as 强调过程或变化,when 常指时间点 | As the clock struck ten, everyone left. |
| until 与 since | until 强调终点,since 强调起点 | We waited until midnight. |
如果明天下雨,我们将取消户外活动。 Unless you leave now, you will miss the train.
除非你现在离开,否则你会错过火车。 When the bell rang, the students entered the classroom.
铃响时,学生们进入了教室。 As the evening came, the lights in the village came on one by one.
夜幕降临,村里的灯一盏盏亮了起来。 We waited until the rain stopped.
我们一直等到雨停。
常用并列连接词搭配与语境信号速查
1. 速查表中的候选词只表示常见意义,最终选择必须符合整句话的逻辑和句法结构。
2. 表示添加时常用 and、also、besides、moreover 和 in addition,其中 besides 还可表示“除……之外”。
3. 表示对比时常用 but、yet、while、whereas、however 和 nevertheless。
4. 表示原因和结果时常用 so、therefore、because、since 和 for,不同词所处位置和词性不同。
5. 表示选择或条件时常用 or、either…or…、unless 和 otherwise。
6. 成对结构必须整体记忆,不能只记住其中一个词而随意替换另一部分。
7. 连接副词、介词短语和连词承担的功能不同,看到逻辑相同并不意味着词性相同。
| 逻辑关系 | 常见候选词或结构 | 典型语境信号 | 快速判断 |
|---|---|---|---|
| 添加 | and, also, besides, moreover, in addition | 两者同时成立、前项之外还有一项 | 空格两侧可同时为真 |
| 对比 | but, yet, while, whereas, however, nevertheless | 前后相反、不同或出乎预料 | 前后不能简单同时成立 |
| 原因与结果 | so, therefore, because, since, for | 一端解释原因,另一端说明结果或依据 | 判断前因后果方向 |
| 选择 | or, either...or... | 二者或多者择一 | 只需其中一项 |
| 条件 | or, otherwise, unless | 前项成立则后项成立,不成立则出现后果 | 还原为 if 条件句 |
| 顺承 | and, then | 前项完成后接着发生 | 按时间先后排列 |
| 固定搭配 | 意义 | 使用提醒 |
|---|---|---|
| both A and B | A和B两者都 | 连接主语时谓语通常用复数 |
| not only A but also B | 不仅A而且B | 两侧成分要对应 |
| either A or B | A或B | 连接主语时按就近一致 |
| neither A nor B | A和B都不 | 连接主语时通常用复数谓语 |
| not A but B | 不A而是B | 前后属于同类内容 |
| as A as B | 与B一样A | 后接形容词或副词性成分 |
任务很难,不过团队还是按时完成了。 The road was icy, so we drove slowly.
道路结冰,所以我们慢慢开车。 Save your work frequently; otherwise, you may lose important data.
经常保存你的工作,否则可能会丢失重要数据。 Besides being a skilled player, he is also a good team leader.
除了是一名技术出色的队员,他还是个优秀的团队领导者。
并列句的标点与句型转换
1. 两个完整分句用 and、but、or、so 等并列连词连接时,通常写成“逗号 + 连词 + 完整分句”。
2. 短小、紧密的并列句可以省略逗号,但较长或两个分句相对独立时通常使用逗号。
3. 两个意义紧密相关的完整分句也可以用分号连接,分号后通常直接进入下一分句。
4. 两个完整分句关系一般时可以使用句号,使表达分为两个独立句子。
5. 也可以把并列句改为从属句,如用 so 改写原因、用 although 改写转折、用 if 改写条件。
6. however 和 therefore 是连接副词,不能用“逗号 + 连接副词”的方式直接连接两个完整句。
7. for 表示理由时通常放在前句之后,前面要有逗号,句型转换时再根据语境改用 because 或 since。
| 组织方式 | 标点或结构 | 例句 |
|---|---|---|
| 并列连词连接完整分句 | 逗号 + and/but/or/so + 完整分句 | The task was hard, but we finished it. |
| 分号连接完整分句 | 完整分句 + 分号 + 完整分句 | The task was hard; we finished it anyway. |
| 句号分开完整分句 | 完整分句 + 句号 + 完整分句 | The task was hard. Nevertheless, we finished it. |
| 从属连词连接 | 从属分句 + 主句 | Although the task was hard, we finished it. |
| 连接副词连接 | 句号或分号 + 连接副词 + 完整分句 | The task was hard; nevertheless, we finished it. |
| 并列句 | 从属句改写 | 改写要点 |
|---|---|---|
| He was tired, so he stopped working. | He stopped working because he was tired. | so 表结果,改用 because 表原因 |
| The task was difficult, but we finished it. | Although the task was difficult, we finished it. | but 表转折,改用 although 表让步 |
| Take the bus, or you will be late. | If you do not take the bus, you will be late. | or 表否则,改用 if 条件句 |
| He stayed in, for it was raining. | He stayed in because it was raining. | for 补充理由,改用 because 更直接 |
道路结冰,所以我们慢慢开车。 The evidence was limited; however, the team continued its investigation.
证据有限;不过,团队仍继续调查。 The task was difficult. We finished it on time.
任务很难。我们还是按时完成了。 Although the road was icy, we drove slowly.
尽管道路结冰,我们还是慢慢地开车。
as…as、so…as 与 not as…as 的比较结构
1. as + 形容词或副词 + as表示两者程度相同,可译为“与……一样……”。
2. not as/so + 形容词或副词 + as表示两者程度不同,可译为“不如……”。
3. not so…as 和 not as…as 基本可以互换,not so…as 在否定句中更常见。
4. 表示肯定等义比较时通常优先使用 as…as,so…as 更多用于 not so…as 结构。
5. 比较结构通常使用相同主语,并把形容词或副词放在两个 as 之间。
6. as…as 结构中不能把第二个 as 随意改为 than,than 用于 more…than 等比较结构。
7. as many 用于可数名词,as much 用于不可数名词,as long as 还可表示长度或时间。
8. 比较双方是同一主语时,谓语通常用单数,并保持时态一致。
| 结构 | 意义 | 例句 |
|---|---|---|
| as + 形容词/副词 + as | 与……一样…… | This book is as interesting as that one. |
| not as + 形容词/副词 + as | 不如…… | He is not as tall as his brother. |
| not so + 形容词/副词 + as | 不如…… | The result was not so good as we had expected. |
| as many + 可数名词复数 + as | 有与……一样多的…… | She has as many books as her brother. |

📌 北京真题 6 题原卷原题,答案按官方解析;单项填空 6 题
John plays basketball well, his favorite sport is badminton.
A. soB. orC. yetD. for
看答案
✅ C. yet(并列连词表示转折)
句子由两个简单句组成,前半句说 John 篮球打得好,后半句说他最喜欢的是羽毛球。两句之间存在逻辑上的矛盾或出乎意料,因此需要用表示转折的连词 yet 来连接。so 表示结果,or 表示选择,for 表示原因,均不符合语境。很多同学容易误选 so,但打球好并不意味着最喜欢篮球,逻辑不成立。
Don’t turn off the computer before closing all programs you could have problems
A. orB. andC. butD. so
看答案
✅ A. or(or 连接祈使句表示后果)
句子前半部分是 Don’t turn off... 的祈使句,后半部分是可能产生的问题。在“祈使句 + 连词 + 陈述句”结构中,or 表示“否则”,用于引出如果不执行指令而产生的负面结果,因此选 or。很多同学容易误选 so,因为从逻辑上看像因果关系,但 so 引导的是结果,而此处强调的是一种警告或潜在威胁,必须用 or。
Some animals carry seeds from one place to another, plants can spread to new places.
A. soB. orC. forD. but
看答案
✅ A. so(并列连词辨析)
句子由两个分句组成,前句说动物将种子从一处搬到另一处,后句说植物能传播到新地方。前后句之间存在明显的因果关系,前句是原因,后句是结果,因此选用表示结果的连词 so。注意 or 表示选择,for 表示原因,but 表示转折,均不符合逻辑。最容易误选的是 for,因为它虽然也表示原因,但引导的是原因分句,而此处逻辑是“因为...所以...”,应选 so。
He is a shy man, he is not afraid of anything or anyone.
A. soB. butC. orD. as
看答案
✅ B. but(并列连词表示转折)
首先分析句子结构,前后两个分句均为独立完整的句子,中间需要填入并列连词。从语义上看,前半句说他“腼腆(shy)”,后半句说他“不怕任何事(not afraid of anything)”,两者在逻辑上构成对比转折,因此选择 but 来连接。最容易误选的 A 选项 so 表示因果关系,与语境不符,因为腼腆并不意味着必然勇敢或胆怯。
I am not afraid of tomorrow, I have seen yesterday and I love today.
A. soB. andC. forD. but
看答案
✅ C. for(并列连词表示原因)
句子由三个分句组成,分析逻辑关系可知:前句是“不害怕明天”,后两句是“见过昨天”且“热爱今天”,后两句是对前句结论的补充说明,即原因。因此选择 for 引导原因并列句,表示“因为”。注意 for 引导的原因通常放在句末作为解释。很多同学容易误选 so,但 so 表示结果,逻辑方向相反,不能说因为不害怕明天,所以见过昨天。
—Peter, please send us postcards we’ll know where you have visited.
—No problem.
A. butB. orC. forD. so
看答案
✅ D. so(并列连词表示结果)
首先分析句子结构,前半句是祈使句,请求 Peter 寄明信片;后半句是结果,即寄了明信片后,我们就能知道他的行程。前后两句存在明显的因果关系,因此选择 so 来连接,表示“以便于/结果就”。注意 A 选项 but 表示转折,B 选项 or 表示选择,与语境不符,最容易误选的是 C 选项 for,因为它虽表示原因,但通常引导原因状语从句且语气较弱,不能用于连接这种结果性的逻辑。
⚠️ 易错点
- 两个完整句不能只用逗号加 however 连接,应改用分号或句号等适当标点。
- because 和 so、although 和 but 不要用于重复连接同一组因果或让步关系。
- 祈使句加 and/or 的前半句用动词原形,不能误用 to do 或 doing。
- either…or、neither…nor、not only…but also 连接主语时,要检查靠近谓语的主语。
- not only 后连接的成分须对称,不能一侧是形容词而另一侧无故换成不对应的完整句。
- instead 是副词,instead of 后接名词性成分,不能混写成 instead of we left。
- for 作为补充理由的连词时,不能照搬 because 的所有位置和问答用法。

四、特殊句式
倒装、强调、省略、it、there be / 祈使句 / 感叹句 / 反意疑问句
17 倒装先认触发条件,再判断全倒还是只提前助动词。
📝 北京怎么考:北京卷阅读、完形中会出现倒装;旧单项填空也可能把倒装放在题干中。写作中可适量使用。
完全倒装:地点与方位
地点/方位词置首 + 谓语 + 名词主语
• 适用动词:be, stand, lie, come 等表示存在、位置或移动的词
• 目的:呈现场景
• 谓语数:由后面的主语决定
• 例外:并非任意地点状语提前都倒装
| 正常语序 | 完全倒装 |
|---|---|
| A tower stands on the hill. | On the hill stands a tower. |
| Two maps are on the wall. | On the wall are two maps. |
| A small house lay at the end of the path. | At the end of the path lay a small house. |
建筑物后面立着一棵老松树。 On the wall hung a portrait of his father.
墙上挂着一幅他父亲的肖像。 At the end of the path lay a small village.
小路尽头坐落着一个小村庄。 Under the bridge were two small boats.
桥下有两只小船。
Here、There 与代词主语
Here/There/方向副词(away, out等)位于句首引出人或物时,名词主语后置,代词主语不后置。
• 名词主语 → 放在谓语后(如:Here comes the bus.)
• 代词主语 → 放在谓语前(如:Here it comes.)
• 例外:这里的 there 表示“那里”,与 there be 句型中的引导词不同。
| 句首成分 | 主语类型 | 常用结构 |
|---|---|---|
| Here / There | 名词 | Here comes the bus. |
| Here / There | 代词 | Here he comes. |
| Away / Out 等 | 名词 | Away flew the birds. |
公共汽车来了。 Here he comes.
他来了。 There stands an ancient pine tree.
那里立着一棵古松。 Away ran the children.
孩子们跑走了。
否定词置首的部分倒装
否定词置首,主语前加助动词/情态动词/be。
• 适用词:never, seldom, hardly, little (几乎不), by no means 等否定或半否定词。
• 结构:助动词/情态动词/be + 主语 + 其他。
• 细节:原句无助动词则借 do/does/did,实义动词还原。
• 例外:not until 置首时,until 从句不倒装,主句倒装。
| 句首成分 | 正常语序 | 部分倒装 |
|---|---|---|
| never | I have never seen it. | Never have I seen it. |
| by no means | I will not give up. | By no means will I give up. |
| not until | We did not leave until the rain stopped. | Not until the rain stopped did we leave. |
| 类别 | 常见信号 |
|---|---|
| 否定副词 | never, seldom, rarely, nowhere, not once |
| 半否定副词 | hardly, scarcely, little(表示‘几乎不’) |
| 否定短语 | by no means, in no way, under no circumstances, at no time, on no account |
我从未看过如此感人的演出。 Seldom does he complain about the workload.
他很少抱怨工作量。 By no means will I give up.
我绝不会放弃。 Not until the rain stopped did we leave the shelter.
直到雨停,我们才离开避雨处。 Little did she realize how much the trip had changed her.
她几乎没有意识到这次旅行给她带来了多大的改变。
Little did I realize that single moment would ruin everything
句中“Little did I realize”体现了否定词置首的部分倒装。当否定词 little 置于句首表示强调时,句子需使用部分倒装结构,即在主语 I 前面加上助动词 did,而谓语动词 realize 恢复原形。全句意思是:我几乎没有意识到那一刻会毁掉一切。
not only 与一……就……
Not only及“刚…就…”短语置于句首时,前分句部分倒装。
• not only连接两个分句:前句倒装,but (also)后通常不倒装。
• 例外:not only只连接主语等成分,不倒装。
• hardly/scarcely…when…(刚…就…):前项置首倒装,前句用had + 主语 + 过去分词,后句用一般过去时。
• no sooner…than…(刚…就…):前项置首倒装,前句用had + 主语 + 过去分词,后句用一般过去时。
| 固定结构 | 倒装部分 | 后一分句 |
|---|---|---|
| not only...but also... | not only 所在分句 | but also 后通常不倒装 |
| hardly/scarcely...when... | hardly/scarcely 所在分句 | when 后不倒装 |
| no sooner...than... | no sooner 所在分句 | than 后不倒装 |
这次旅行不仅开阔了我的眼界,还拉近了我们的距离。 Not only the students but also their teacher enjoyed the performance.
不仅学生们享受了演出,他们的老师也享受了演出。 Hardly had we sat down when the lights went out.
我们刚坐下,灯就灭了。 No sooner had he arrived than the bell rang.
他刚到,铃就响了。 Scarcely had she finished speaking when the audience interrupted.
她刚说完,观众就打断了她。
Not only are rewarding experiences remembered better, but negative
consequences are also easily recalled.
本句体现该知识点之处为“Not only are rewarding experiences remembered better”。当 Not only 置于句首引导分句时,该分句需采用部分倒装结构,即谓语动词(此处为被动语态的助动词 are)置于主语(rewarding experiences)之前。而 but 引导的后半句保持正常语序。全句意为:积极的经历记得更牢,负面的后果也容易被回想起来。
only 加状语置首
only + 状语置首,主句部分倒装
• only + 副词/介词短语/状语从句 → 主句倒装
• 例外:only 修饰主语 → 不倒装
• only + 状语从句 → 仅主句倒装,从句不倒
| only 修饰的成分 | 示例 | 是否倒装 |
|---|---|---|
| 主语 | Only two students knew the answer. | 不倒装 |
| 副词或介词短语 | Only in this way can we solve it. | 主句倒装 |
| 状语从句 | Only when he arrived did we start. | 主句倒装,从句不倒装 |
只有用这种方法,我们才能解决这个问题。 Only when the rain stopped did they leave.
只有雨停后,他们才离开。 Only after checking the figures did she make the decision.
只有核对了这些数字后,她才作出决定。 Only two students knew the answer.
只有两名学生知道答案。
The world has always had influential people, for instance, but only now do we have “Influencer”.
句中“only now do we have”体现了该语法点。当 only + 时间状语(now)置于句首时,主句需使用部分倒装结构,即在主语 we 前面加上助动词 do 来实现强调。全句意思是:世界上一直有影响力的人,但直到现在才出现了“网红”这一称谓。
so、neither、nor 表示也
“也”的表达:so/neither/nor + 助动词/be/情态动词 + 主语
• 肯定句用 so
• 否定句用 neither 或 nor
• 动词种类与时态承接前句
• 人称和数随新主语变化
• 例外:so + 主语 + 助动词 表示“的确如此”,确认同一件事,不表示另一个人也如此
| 含义 | 结构 | 示例 |
|---|---|---|
| 另一人也如此 | So do I. / So can she. | I can swim, and so can she. |
| 另一人也不如此 | Neither did I. / Nor is he. | I cannot drive, and neither can he. |
| 确认的确如此 | So he did. | ‘You were right.’ ‘So you were.’ |

我准备好了,他也准备好了。 “You did well,” Tom said. “So I did.”
“你做得好。”汤姆说。“确实如此。”
as、though 让步前置
as/though引导让步从句时,表语(形/副/名)或动词原形可前置。
• as:必须前置。
• though:可用前置,也可按普通语序。
• although:不用前置格式。
• 名词前置:单数可数名词去冠词(如 Child as he is)。
• 例外:非助动词前置,不适用助动词移至主语前的规则。
| 前置成分 | 结构 | 示例 |
|---|---|---|
| 形容词 | 形容词+as/though+主语+be | Tired as she was... |
| 名词短语 | 名词短语+as+主语+be | Child as he was... |
| 动词相关成分 | Try/Even if...+as+主语+情态动词 | Try as he might... |

尽管他想尽办法,仍打不开罐子。 Silly as it sounds, the plan is worth trying.
这个计划听起来有点傻,但值得一试。 Though she was tired, she continued working.
尽管她很累,她还是继续工作。
虚拟条件句省略 if
虚拟条件句中若有 were, had, should,可省 if 并将该词提前。
• Had I known... = If I had known...
• Were I you... = If I were you...
• Should you need... = If you should need...
• were to 结构改为:Were + 主语 + to do
• 否定式:not 通常留在主语后
• 例外:并非所有 if 条件句都能如此改写
| 带 if 的虚拟条件句 | 省略 if 后 |
|---|---|
| If I had known the truth... | Had I known the truth... |

如果你需要帮助,请告诉我。 Had he not studied harder, he would not have passed.
如果他当时学习再努力一些,本来就通过了考试。
so、such 引导的倒装句
• so+形容词 置于句首时可用 so+形容词+be+主语 的倒装形式。
• so+副词 修饰实义动词时,要用 do/does/did 支持倒装,实义动词使用原形。
• such+a/an+形容词+单数可数名词 置于句首时,也可把 be 提到主语前。
• so 或 such 引导的结果状语从句保持正常语序,不随主句一起倒装。
| 句首形式 | 倒装结构 | 示例 |
|---|---|---|

孩子们兴奋极了,全都跳了起来。
主句倒装与从句不倒装
• only when...、not until...、hardly...when...、no sooner...than... 等结构中,倒装的是主句。
• 引导时间或条件的前置从句内部保持正常语序,不能把从句中的助动词也提前。
• not until 表示‘直到……才……’,only when 表示‘只有当……时……’,两者含义不同。
• hardly/scarcely 与 when 搭配,no sooner 与 than 搭配,两个分句中通常只有前一分句倒装。
• when、if、because 等从句单纯置于句首时,主句通常仍用正常语序。
| 结构 | 倒装部分 | 不倒装部分 |
|---|---|---|
| Only when..., ... did... | 主句 | when 从句 |
| Not until..., ... did... | 主句 | until 从句 |
| Hardly had..., when... | had 所在分句 | when 分句 |
| No sooner had..., than... | had 所在分句 | than 分句 |

倒装句还原与易错检查
• 还原完全倒装时,把名词主语移回谓语之前,还原成‘主语+谓语’语序。
• 还原部分倒装时,把主语移到已经提前的助动词、be 或情态动词之后。
• 谓语的人称和数始终以真正的主语为依据,不能根据前置状语判断。
• 使用 do/does/did 支持倒装时,实义动词必须用原形,did 句尤其不能写成 did he went。
• 存在句 There is/are... 和确认句 So he did. 不属于需要倒装的结构。
• 一个句子通常只倒装被触发的主句或分句,不能把主句和从句同时倒装。
| 检查项目 | 正确形式 | 常见错误 |
|---|---|---|
| 部分倒装语序 | Never have I seen it. | Never I have seen it. |
| do 支持后的动词形式 | Not until he came did she leave. | Not until he came did she left. |
| 谓语与主语一致 | The books are on the desk. | The books is on the desk. |
| 确认句 so | So you are. | So are you. |
山上矗立着一座高高的塔。 Never have I encountered such a problem.
我从未遇到过这样的问题。 Had we known the truth, we would have acted differently.
如果我们知道真相,就会采取不同的做法。 So you are.
原来如此。
⚠️ 易错点
- 地点状语提前不保证倒装;要看呈现场景的用法、谓语类型和主语类型。
- Here 后若是代词应说 Here he comes,不能写 Here comes he。
- only 修饰主语不倒装;Only Mary knows the truth 不能借 does 倒装。
- Not until 从句置首时倒装主句,不能把两个分句都倒装。
- 借 did 后实义动词用原形,不能写 Never did I saw。
- as 让步前置和部分倒装不是同一种移位,不要写成 Tired as was she。

18 强调句去掉强调框架、还原原句,检查结构与意思。
📝 北京怎么考:北京卷阅读和完形中可见 It is/was…that/who 与 do 强调;阅读要识别强调对象,写作可用于突出原因、时间或人物。
基本框架与强调对象
It is/was + 被强调部分 + that + 其余部分
• 强调对象:主语、宾语或状语
• 强调人时:that 可用 who 代替
• 时态选择:is/was 根据时间选,that 后谓语保持原时态
• 例外:不能强调谓语,不用来强调形容词表语
| 强调对象 | 结构示例 |
|---|---|
| 主语 | It was Lily who/that sent me a card yesterday. |
| 宾语 | It was a card that Lily sent me yesterday. |
| 时间状语 | It was yesterday that Lily sent me a card. |
| 地点状语 | It was at the school library that Lily found the card. |
| 原因状语 | It was because the bridge was closed that we changed our route. |
正是我们共同的目标让团队凝聚在一起。 It was the letter that she had been looking for.
她一直在找的就是那封信。 It was in the school library that I found the missing notebook.
我正是在学校图书馆找到了丢失的笔记本。 It was because the bridge was closed that we changed our route.
正是因为大桥关闭,我们才改变了路线。 It was Tom who broke the world record.
打破世界纪录的是汤姆。
It is the fitness level of our body that helps us fight these diseases.
本句体现了“It is the fitness level of our body that...”这一结构。其框架为 It is + 被强调对象 + that + 其他成分,其中 the fitness level of our body 是被强调的主语,被置于 It is 和 that 之间以起到突出作用。全句意思是:正是我们身体的体能水平帮助我们抵抗这些疾病。
去框架还原法
去掉 It is/was 和 that/who,将强调部分还原至原位,能组成完整合理句即为强调句。
• 判定标准:还原后结构完整且意思合理。
• 警惕陷阱:不能仅凭 It is...that 形式判断。
• 例外:It is clear that he is right 中 clear 是表语,that 从句是主语,还原为 Clear he is right 不通,故非强调句。
| 句型 | 还原或结构检验 | 结论 |
|---|---|---|
| It was in the library that I found the book. | 可还原为 I found the book in the library. | 强调句 |
| It is clear that he is right. | 去掉框架后不能得到 Clear he is right. | 主系表句 |
| It is the village where she grew up. | where 从句修饰 village,was 是系动词。 | 定语从句结构 |
| It is important that we should act now. | it 是形式主语,that 引导主语从句。 | 虚拟语气结构 |
我正是在学校图书馆找到了丢失的笔记本。 It is clear that he is right.
显然他是对的。 It is the village where she grew up.
那就是她长大的村庄。 It is important that we should protect the environment.
保护环境很重要。
Therefore, it is the individual, not the government, who should pay for
their university education.
句中体现该方法的结构为“it is...who...”。通过去掉强调框架 it is 和 who,可还原为 the individual, not the government, should pay for their university education。该句通过此结构将主语置于框架中以突出重点。全句意为:因此,应该是个人而非政府来支付他们的大学教育费用。
强调地点、时间与原因从句
强调句型统一使用 It is/was ... that ... 结构,无论强调成分是什么。
• 强调地点/时间状语:必须用 that,禁用 where/when。
• 强调原因从句:整体放入强调位置,常用 It was because... that...。
• 原因从句内部:保持结构完整。
• 语法陷阱:不要将 that 误认为从句内部的成分。
| 强调内容 | 结构 | 示例 |
|---|---|---|
| 地点 | It was in the library that... | It was in the library that we met. |
| 时间点 | It was yesterday that... | It was yesterday that we met. |
| 时间从句 | It was when...that... | It was when we arrived that the meeting began. |
| 原因从句 | It was because...that... | It was because he was ill that he was absent. |
我正是在学校图书馆找到了丢失的笔记本。 It was when I worked as a volunteer that I learned to listen patiently.
我正是在做志愿者时学会了耐心倾听。 It was because the bridge was closed that we changed our route.
正是因为大桥关闭,我们才改变了路线。 It was for this reason that she changed her mind.
正是出于这个原因,她改变了主意。
Similarly, the corporate world has certainly known its fair share of disruption, yet it is only in the last couple of decades that the “Disruptor” has become a recognisable figure in the way we talk about big business.
句中“it is only in the last couple of decades that...”体现了该语法点。结构为“it is + 被强调的时间状语 + that + 其他成分”,通过将时间状语置于 it is 和 that 之间来突出时间。全句意为:同样,企业界无疑经历过不少动荡,但直到最近几十年,“颠覆者”才成为我们讨论大企业时一个被认可的角色。
not until 的强调
It is/was not until + 时间点/从句 + that + 肯定形式主句
• not随until一起移入强调位置
• that后不再重复not
• that后不采用倒装语序
| 句型 | 结构 | 示例 |
|---|---|---|
| 强调句 | It was not until...that + 肯定句 | It was not until the meeting ended that I checked my phone. |
| Not until 倒装 | Not until... + 助动词/情态动词 + 主语 | Not until the meeting ended did I check my phone. |
| 普通语序 | 主句 + not until... | I did not check my phone until the meeting ended. |
直到会议结束,我才查看手机。 It is not until you understand the problem that you can solve it.
只有理解了问题,你才能解决它。 Not until the bell rang did we leave the classroom.
直到铃声响起,我们才离开教室。 I did not check my phone until the meeting ended.
直到会议结束我才查看手机。
疑问句与嵌入语序
强调句变疑问句:直接问用倒装,进从句用陈述。
• 一般疑问句:Is/Was it + 强调部分 + that...?
• 特殊疑问句:疑问词 + is/was it that...?
• 嵌入宾语从句:疑问词 + it is/was that...(恢复陈述语序)。
• 例外:从句中不能保留 was it。
| 句型 | 语序 | 示例 |
|---|---|---|
| 直接一般疑问句 | Is/Was it + 强调部分 + that...? | Was it your sister that designed the poster? |
| 直接特殊疑问句 | Wh + is/was it + 强调部分 + that...? | Why was it that the train stopped? |
| 特殊疑问句宾语从句 | Wh + it is/was that + 强调部分... | I wonder why it was that the train stopped. |
| 一般疑问句宾语从句 | whether/if + it is/was + 强调部分 + that... | I wonder whether it was Tom that called. |
设计这张海报的是你姐姐吗? Why was it that the train stopped?
火车究竟为什么停了? I wonder why it was that the train stopped.
我想知道火车究竟为什么停了。 Do you know whether it was your sister that designed the poster?
你知道海报是不是你姐姐设计的吗?
与定语从句和时间句型辨析
不要看到 It 就盲选 that,需区分定语从句和时间句型。
• It is the village where... 是主系表句,where 引导定语从句修饰 village,不可还原。
• It was three days before... 是 before 时间句型,意为“三天后才...”。
• 强调时间用 It was three days later that...。
| 结构类型 | 识别信号 | 示例 | 判断 |
|---|---|---|---|
| 定语从句 | 名词后接 where/which/that 从句 | It is the village where she grew up. | 普通主系表句 |
| 地点强调句 | it is/was 与 that 之间有地点成分 | It was in the village that she grew up. | 强调句 |
| before 时间句型 | It was + 时间段 + before + 主谓 | It was three days before he returned. | 三天后才回来 |
| 虚拟语气 | It is high time that... | It is high time that we started. | should start |
| 报告结构 | it is/was said/believed/reported that... | It is said that hard work pays off. | 不是强调句 |
那就是她长大的村庄。 It was in that house that my uncle wrote his first novel.
我叔叔正是在那所房子里写了他的第一部小说。 It was three days before he returned.
三天后他才回来。 It is high time that we started.
现在是我们该出发的时候了。 It is said that regular exercise reduces stress.
据说,规律锻炼能减轻压力。
do、does、did 强调谓语
肯定句中用 do/does/did + 动词原形表示“确实、的确”。
• 时态和人称变化由 do/does/did 承担。
• 仅用于一般现在时或一般过去时。
• 后面必须用动词原形,不可保留三单或过去式。
• 祈使句可用 Do + 原形表达恳切邀请或叮嘱。
• 例外:已有 be、助动词或情态动词的句子,通过重读它们加强语气,不再加 do。
| 时态或句型 | 结构 | 示例 |
|---|---|---|
| 一般现在时 | does + 动词原形 | He does know the answer. |
| 一般过去时 | did + 动词原形 | I did send the message. |
| 祈使句 | Do + 动词原形 | Do come and join us. |
| 否定或疑问句 | 重读原有助动词 | Did you really finish the work? |
| be 或情态动词句 | 重读已有助动词 | He is indeed ready for the interview. |
你的鼓励确实对我有帮助。 I did send the application before the deadline.
我确实在截止日期前提交了申请。 Do come and join our discussion.
请一定来参加我们的讨论。 Did you really finish the work on time?
你真的按时完成了工作吗? He is indeed ready for the interview.
他确实已经准备好面试了。
Although my daughter didn’t win, she did help expose one of the worst pieces of advice I have ever given.
句中“did help”体现了该语法点。结构为“do/does/did + 动词原形”,此处用助动词 did 强调谓语动词 help,用以增强肯定语气,与前文的否定句形成对比。全句意思是:虽然我的女儿没有获胜,但她确实帮助揭露了我曾经给出的最糟糕的建议之一。
强调句中的时态呼应与标志词速查
- 框架时态:is/was 表示整个强调表达的时间指向,不能只按保留谓语的时态机械判断。
- 谓语时态:that/who 后保留原句谓语时态,可使用高中核心八时态。
- 同句并存:强调部分可含时间状语,因此 is/was 与保留谓语的时态不一定完全相同。
- 报告结构:It is/was said/believed/reported that... 中 that 前没有被强调成分,通常不是强调句。
- 结构检验:只有 it 与 that 之间能指出一个独立焦点成分,才按强调句分析。
| 强调框架 | 常见时间语境 | 保留谓语的常见时态 | 示例 |
|---|---|---|---|
| It is | 现在、当前或未来安排 | 现在时、将来时等 | It is in 2025 that the new policy will take effect. |
| It was | 过去的时间或过去语境 | 过去时、过去完成时等 | It was in 2020 that the policy was introduced. |
| 谓语时态 | 常见标志词或结构 | 保留部分的示例 |
|---|---|---|
| 一般现在时 | always, usually, often, every day, on Mondays | He usually checks the weather before breakfast. |
| 现在进行时 | now, at present, Look!, Listen! | He is working on the report now. |
| 现在完成时 | since, for, already, yet, just, ever, never | He has finished the report. |
| 一般过去时 | yesterday, ago, last week, in 2020 | He checked the museum yesterday. |
| 过去进行时 | at eight last night, when..., while... | He was working on the report at eight last night. |
| 过去完成时 | before, after, by the time, already | He had finished the report before the meeting began. |
| 一般将来时 | will, be going to, tomorrow, next week, in three days | He will arrive tomorrow. |
| 过去将来时 | would + 动词原形, the next day, in the following year | He would arrive the next day. |
这项政策正是在2020年出台的。 It is in 2025 that the new policy will take effect.
新政策将于2025年生效。 It was when the bell rang that we stopped working.
正是在铃声响起时,我们才停止工作。 It is on Mondays that the museum opens.
博物馆是在每周一开放的。 It is said that regular exercise reduces stress.
据说,规律锻炼能减轻压力。
that 与 who 的选用
- 稳妥用法:主语、宾语和状语等被强调成分均用 that 引导。
- who 的条件:强调人作主语时可用 who 替换 that。
- 宾语限制:强调人作宾语时仍用 that,不使用 who。
- 地点和时间:仍用 that,不使用 where/when。
- 定语从句另论:定语从句中的 who/which/that 要根据先行词和从句中的成分选择。
| 被强调成分 | 高考稳妥连接词 | 示例 |
|---|---|---|
| 人作主语 | that/who | It was Tom who helped her. |
| 物作主语 | that | It was the machine that broke down. |
| 人作宾语 | that | It was his teacher that helped him. |
| 物作宾语 | that | It was the book that she borrowed. |
| 时间、地点或原因 | that | It was yesterday that they arrived. |
| 定语从句识别信号 | 常用连接词 | 示例 |
|---|---|---|
| 先行词为人,从句缺少主语 | who/that | The boy who helped me is Tom. |
| 先行词为物,从句缺少宾语 | which/that | The book which I borrowed is interesting. |
| 先行词为地点,从句不缺主语和宾语 | where | The village where she grew up is beautiful. |
| 先行词为时间,从句不缺主语和宾语 | when/that/on which | The day when we met is special. |
帮助那个小女孩的是汤姆。 It was his teacher that helped him.
帮助他的是他的老师。 It was the book that she had been looking for.
她一直在找的就是那本书。 It was yesterday that they arrived.
他们正是在昨天到达的。 It was because he was ill that he was absent.
他缺席正是因为生病。
only 引导的倒装强调
- 基本结构:Only + 状语置于主句开头时,主句使用部分倒装。
- 倒装范围:句中有助动词或情态动词时,只把第一个助动词或情态动词放在主语前。
- 无助动词时:主句没有助动词时用 do/does/did 构成倒装。
- 主语位置:Only + 主语位于句首时,主句通常不倒装。
- 位置要求:只有 Only + 状语位于主句开头时,才使用这一倒装结构。
- Not only:Not only 位于句首也要倒装,但它是并列连词,通常与 but also 搭配。
| 结构 | 语序 | 示例 |
|---|---|---|
| Only + 时间从句 | Only when... + 助动词 + 主语 | Only when we work together can we solve the problem. |
| Only + 地点或介词短语 | Only in... + 助动词/情态动词 + 主语 | Only in this way can we solve it. |
| Only + 副词 | Only then + 助动词 + 主语 | Only then did she realize the truth. |
| Only + 主语 | 主句不倒装 | Only he can solve the problem. |
| Not only...but also | Not only + 助动词 + 主语... | Not only did he finish the work, but he also helped his sister. |
只有齐心协力,我们才能解决这个问题。 Only in this way can we solve it.
只有用这种方法,我们才能解决它。 Only then did she realize the truth.
直到那时她才意识到真相。 Only after the meeting ended did we leave.
直到会议结束,我们才离开。 Not only did he finish the work, but he also helped his sister.
他不仅完成了工作,还帮助了妹妹。
强调句与定语从句的转换
- 先还原:把强调句还原成正常的主谓句,再判断被强调的是主语还是宾语。
- 主语焦点:可改写为 the + 人或物 + who/that/which 从句。
- 宾语焦点:可改写为 the + 人或物 + who/that 从句或 what 引导的名词性从句。
- 状语焦点:通常先还原为带状语的普通句,不能机械套用定语从句。
- 连接词选择:根据先行词和从句中缺少的主语或宾语选择 who、which 或 that。
- 信息关系:改写后表达相近信息,但原来的排他性焦点可能发生变化。
| 焦点类型 | 强调句 | 常见相对表达或普通句 |
|---|---|---|
| 人作主语 | It was Tom who won the race. | Tom is the boy who won the race. |
| 物作主语 | It was the company that launched the project. | The company is the organization that launched the project. |
| 人作宾语 | It was Mary that Tom met. | Mary is the person that Tom met. |
| 物作宾语 | It was the book that Tom read. | The book is what Tom read. |
| 地点状语 | It was in the lab that we completed the experiment. | The experiment was completed in the lab. |
赢得比赛的是汤姆。 Tom is the boy who won the race.
赢得比赛的男孩是汤姆。 It was the book that Tom read.
汤姆读的是那本书。 The book is what Tom read.
汤姆读的就是那本书。 It was in the lab that we completed the experiment.
我们正是在实验室完成了实验。
⚠️ 易错点
- 强调地点、时间仍用 that,不能写 It was in Beijing where I met him 来表达本章的强调框架。
- 去框架判断要把强调成分放回原位,不能随意丢掉 in、because 等必需成分。
- It was not until…that 后用正常肯定语序,不能再写 did he leave 或 he did not leave。
- 强调句嵌入宾语从句要用陈述语序:I wonder where it was that…。

19 省略与替代省去重复成分前,先确认它能从上下文还原。
📝 北京怎么考:北京语法填空可直接考查状语从句省略后的 doing/done,如2025年第17题;阅读中还需补回省略谓语、辨认替代内容。本章收录北京卷语法填空 2 空(2023—2024 年中的 2 年)。
状语从句省略的条件
时间、条件、让步状语从句中,主语一致且谓语含be时,可同时省略主语和be。
• 保留连接词(when/while/if/though/unless等)及其后成分。
• 还原后需检查逻辑主语,确认动作或状态实际属于谁。
• 例外:主语不一致时不可省略。
| 省略形式 | 可补全形式 |
|---|---|
| While waiting | While I was waiting |
| If careful | If you are careful |
| Though tired | Though he was tired |
| Unless invited | Unless he is invited |
等公交车时,我复习了笔记。 If (you are) careful, you will avoid the mistake.
如果你小心,就能避免这个错误。 Though tired, the players kept training.
尽管疲惫,队员们仍坚持训练。 He will not come unless (he is) invited.
除非受到邀请,否则他不会来。
省略后的 doing、done 与短语
省略后保留的形式由原结构和主被动关系决定。
• when/while + doing:主语主动做某事
• when/if + done:主语被……或处于某种状态
• 可保留形容词或介词短语
• 例外:if necessary, if possible, when possible 省略 it is,主句主语不必是 it
| 省略式 | 可还原结构 | 常见意义 |
|---|---|---|
| while reading | while he was reading | 主动或正在进行 |
| when invited | when he was invited | 被动 |
| when completed | when it was completed | 完成或被动 |
| if necessary | if it is necessary | 无人称固定表达 |
| if any | if there is any | 存在 |
| when in doubt | when he is in doubt | 状态 |
如果获得通过,这项提议将在下个月付诸实施。 While repairing the bike, he found a broken cable.
修自行车时,他发现一根断裂的电缆。 When in doubt, ask your teacher.
如有疑问,请询问老师。 If necessary, we can arrange a second meeting.
如有必要,我们可以安排第二次会议。
When asked what advice he’d give other entrepreneurial youth, he says, “Prepare and have your family’s support. It is important to know from the beginning that there are a lot of highs and lows, and there is no such thing as overnight success.”
句中“When asked”体现了该知识点。当状语从句的主语与主句主语一致且谓语为被动结构(be + 过去分词)时,可省略主语和系动词 be,仅保留过去分词构成缩写的状语从句。此处原结构为“When he is asked”,省略后保留 asked 表示被动。全句意为:当被问到会给其他创业青年什么建议时,他说:“做好准备并获得家人的支持。”
不定式省略时保留 to
重复的不定式可省略动词及其后成分,但保留 to。
• 肯定式:保留 to(如 would like to, want to, be asked to)。
• 否定式:保留 not to。
• 状态/被动/完成:保留 to be 或 to have。
• 例外:to 是介词时(如 look forward to),按介词结构处理。
| 保留形式 | 可补全结构 | 说明 |
|---|---|---|
| to | to do it | 重复动作省去 |
| not to | not to do it | 否定形式保留 |
| to be | to be cleaned | 被动的 be 保留 |
| to have | to have done it | 完成式的 have 保留 |
| to doing | to hearing from you | 介词 to 后接动名词 |
他答应帮忙,但后来还是拒绝了。 She wanted to go, but her parents advised her not to.
她想去,但父母劝她不要去。 He was supposed to be there, but he didn't have to be.
他本来应该到场,但他不必到场。 We look forward to hearing from you soon.
期待你的回信。
so、not 替代整个判断
so 替代肯定判断,not 替代否定判断。
• I think so = 我认为(前面说的)是这样
• I hope not = 我希望(前面说的)不是这样
• 肯定常用:I think/believe/suppose/hope so
• 否定常用:I don't think so, I hope not, I'm afraid not
• 例外:不能把任何动词都硬接 so/not
• if so = 如果是这样
• if not = 如果不是这样
| 表达 | 完整含义 |
|---|---|
| I think so | 我认为前文的判断是肯定的 |
| I don't think so | 我认为前文的判断是否定的 |
| I hope not | 我希望前文的内容不是这样 |
| if so / if not | 如果前文成立 / 如果前文不成立 |
| So do I | 我也这样做 |
| Neither do I | 我也不这样做 |
会下雨吗?我希望不会。 Is that your car? I think so.
那是你的车吗?我想是吧。 If so, we will continue; if not, we will change the plan.
如果情况属实,我们就继续;否则就修改计划。 Can you swim? So can I.
你会游泳吗?我也会。 Can you swim? Neither can I.
你会游泳吗?我也不会。
do 与助动词替代谓语
do/does/did/do so 用来替代前面出现过的实义动词短语。
• do so 替代前面提到的动作。
• do/does/did 单独保留时,替代重复的实义动词短语。
• 例外:have、be、情态动词可作为省略结构的支点。
• 还原时需同时恢复否定、时态及动作内容。
• 翻译时不可将每个 do 都译成“做”。
| 形式 | 替代对象 | 例句 |
|---|---|---|
| do so | 前文提到的具体动作 | cancel the ticket |
| do/does/did | 重复的实义动词短语 | She works here, and so do I. |
| have/has/had | 重复的完成时谓语 | Have you finished? Yes, I have. |
| be | 重复的 be 谓语 | Are you ready? Yes, I am. |
| 情态动词 | 重复的情态动词谓语 | Can you drive? Yes, I can. |
我原以为机器会运转,但它没有运转。 Anyone wishing to cancel should do so before Friday.
任何想取消的人都应在星期五之前取消。 Does he live here? Yes, he does.
他住在这里吗?是的。 Have you finished the work? Yes, I have.
你完成工作了吗?是的。 Are you ready? Yes, I am.
你准备好了吗?是的。
That project, which I could complete from my sofa instead of in the burning heat of the desert, not only survived the lockdown but worked where traditional methods didn’t.
句末的“didn’t”体现了该知识点。这里 didn’t 是助动词 do 的过去时否定形式,用以替代前面出现过的谓语动词 work,避免重复,完整结构应为“didn’t work”。全句意为:那个项目让我能坐在沙发上而非在酷热的沙漠中完成,它不仅在封锁期间得以延续,而且在传统方法失效的地方发挥了作用。
并列结构中的共同成分
并列结构中,共同成分在不引起歧义时可省略。
• 并列分句或短语:共同主语、谓语或其他成分可省。
• 两个不定式并列:第二个 to 可省。
• 比较结构:已知成分常省。
• 补回要求:保持语法层次相同,检查并列的是动词、名词还是分句。
• 例外:引起歧义时不可省。
| 省略形式 | 可补全形式 |
|---|---|
| and took off his coat | and he took off his coat |
| can stay or go | can stay or can go |
| to read and write | to read and to write |
| as tall as I | as tall as I am |
| her mother a nurse | her mother is a nurse |

她父亲是医生,她母亲是护士。 She likes to read and write.
她喜欢读书和写字。 You can either call or email me.
你可以打电话,也可以给我发电子邮件。 The hotel is cheaper than the restaurant.
这家酒店比那家餐馆便宜。
It is taught to artists and engineers, but much less often to scientists.
句中 but 后的成分 "much less often to scientists" 体现了该知识点。为了避免重复,此处省略了与前半句相同的主语和谓语 "it is taught"。结构上,but 连接两个并列成分,后半部分仅保留了频率状语和对象。全句意为:这种技能会教给艺术家和工程师,但教给科学家的频率要低得多。
名词替代与指代的边界
用替代词或省略来避免重复,阅读时必须回找所指。
• one/ones:替代上文出现的可数名词,指同类另一个或另一些。
• it:指已经确定的同一事物。
• that/those:常在比较中替代名词。
• 替代词仍占句子成分,省略则是成分未写出。
| 替代形式 | 指代范围 | 主要限制 |
|---|---|---|
| one/ones | 同类中的另一个或另一些 | 被替代名词通常为可数名词 |
| it | 已经确定的同一事物 | 所指对象必须明确 |
| that/those | 前文重复的名词短语 | 常用于比较结构 |
| the former/the latter | 先前提到的两个事物 | 通常按出现顺序对应 |

宾语从句中 that 的省略
- that 在一般宾语从句中只起连接作用,可以省略,如 I believe (that) he is right。
- 宾语从句有完整主语和谓语时,才可省略 that。
- whether/if 和 what/who 等疑问词承担从句成分,不能省略。
- the fact that、the reason that 等固定结构中的 that 不能省。

|---|---|---|
| I believe (that) he is right | 能 | that 只起连接作用 |
| He said (that) he would come | 能 | 从句结构完整 |
| I wonder whether/if he agrees | 不能 | whether/if 承担从句成分 |
| the fact that he was late | 不能 | that 构成固定名词结构 |
| It is clear that everyone was tired | 不能 | that 引导主语从句 |

我想知道他是否同意。 The fact that he was absent surprised us.
他缺席这一事实使我们感到惊讶。
省略与替代的识别信号速查
- 看到连接词后像残句,先检查是否省略了共同主语、共同谓语或 be 动词。
- 看到 and/or 两侧结构不对称时,可检查并列成分能否共用。
- 看到 than/as 后的成分不完整时,可检查比较结构中的共同成分。
- 看到 so/neither/nor + 助动词时,应按前文肯定或否定命题补全。
- 看到 do/does/did 或 one/ones 时,应分别按谓语替代或名词替代回找上文。
- 所有补全都要核对逻辑主语、主动被动、时态和指代。
| 识别信号 | 常见补全方式 | 例句 |
|---|---|---|
| if/when/while/though + 动词或分词 | 从句主语 + be | If (you are) ready, you can start. |
| and/or + 谓语 | 共同主语、助动词或情态动词 | can stay or go |
| to + V and V | 两个不定式共用 to | to read and write |
| than/as + 成分 | 共同 be 动词、形容词或副词 | as tall as I |
| so + 助动词 + 主语 | 前文肯定行为 | So do I |
| neither/nor + 助动词 + 主语 | 前文否定行为 | Neither do I |
| do/does/did (not) | 前文重复的实义动词 | She works here, and so do I. |

When (see) from afar, the mangrove forests appear more splendid.
看答案
✅ seen(从句省略中的过去分词)
完整结构为 when they are seen;从句主语与 see 是被动关系,省略主语和 be。

看答案
✅ asked(从句省略中的过去分词)
完整结构为 when he was asked;从句主语与 ask 为被动关系,省略主语和 be。

- When asked 的主语是被问的人,不能因主句主动就一律填 asking。
- would love to 中 to 可代表整个重复的不定式,不能在要求保留标记的句子中随手删去。
- used to be 的 be 往往要保留,不能把所有不定式都缩成一个 to。
- I hope not 是常见否定回答,不要套用 I don't hope so 表达同一常规意思。
- 补出省略谓语时要带回否定和时态,didn't 在语境中常相当于 didn't work。

It is said that 等报告句型
It is said that... 及其转换句型,用于表达“据说/据报道/人们相信/众所周知……”
• It 是形式主语,that 从句是真正主语。
• 可转换为:主语 + be said + to do。
• 若不定式动作早于 said 的时间,用 to have done。
• 完成时、过去时的报告结构按原意理解。
| 报告结构 | 含义 | 例句 |

第几次:完成时搭配
It/This is the first/second…time (that) + 主语 + 现在完成时,表示截至现在第几次做某事。
• 主句为 It/This was the first…time 时,过去叙事通常用过去完成时。
• 例外:It's time (for sb) to do… 表示“该做了”。

• It will be + 时间段 + before...:还要多久才...,before 从句用一般现在时。
• It was + 时间段 + before...:过了多久才...。
• It was + 钟点 + when...:某事发生时的时间。
| 主句结构 | 从句常用时态 | 意义 |

他们过了将近三周才收到回复。 It was nearly midnight when the guests left.
客人们离开时已近午夜。
强调框架中的 it
It is/was + 强调部分 + that/who... 是强调框架,it 不指代前文事物。
• 还原法:去掉框架将强调部分放回原位,可还原原句。
• 引导词:强调时间、地点用 that。
• 辨别点:看句子能否还原,而非看 that 前是否为时间词。
• 例外:强调人可用 who。
| 强调对象 | 例句 | 注意 |
|---|---|---|
| 时间 | It was in 2020 that I met her. | 通常用 that |

• 表达喜好:like/love/hate/appreciate it when/if…
• 礼貌请求:I would appreciate it if…
• 固定搭配:depend on it that… / see to it that…
• 例外:make it 可表示成功做到或及时到达,不一定是形式宾语。

it 与 one/ones 的区别
it 指前文已经确定的同一个单数事物。
one 指同类中的一个或另一个事物,通常替代可数单数名词。
ones 是 one 的复数形式,替代可数复数名词。
one/one's 可泛指任何人,one's 表示“某人的”。
one of... 表示“一群中的一个”,这一结构中通常不能把 one 换成 it。
| 形式 | 指代或用法 | 例句 |
|---|---|---|
| it | 前文已确定的同一个单数对象 | I found my phone and turned it on. |
| one | 同类中的一个或另一个 | I need a pen, so I'll buy one. |

我需要一部新手机,所以明天买一部。 These chairs are old, so we are going to replace them with new ones.
这些椅子很旧了,所以我们准备换成新的。 One should do one's best to help others.
每个人都应该尽最大努力帮助别人。
it 与 that/those/them 的区别
it 是第三人称单数中性代词,通常指已知的单数事物或前文内容。
作指示代词时,that/this 可指特定的事物、事实或比较对象。
those/these 是指示代词的复数形式,带有远近指示或比较关系。
them 是人或物的复数宾格,通常指前文已经提到的一群事物或人。
在“名词 + of + 物主代词”结构中,可用 that of mine 或 those of mine 表示同类中的某一个或一些。
that 作连接词引导从句时,不属于代词指代比较。
| 形式 | 基本特点 | 例句 |
|---|---|---|
| it | 已知的单数事物或事实 | The parcel is here. Please open it. |
| that/this | 带有特定、指示或比较意味 | That is exactly what I mean. |
| those/these | 指示代词复数形式 | These are the photos we took. |
| them | 人或物的复数宾格 | I bought two tickets and kept them. |
包裹在这里,请打开它。 That is exactly what I mean.
那正是我的意思。 These are the photos we took on the trip.
这些是我们旅行时拍的照片。 I bought two tickets and kept them.
我买了两张票,并把票留了下来。
固定主语 it 句型速查
这类固定句型中的 it 只占主语位置,没有需要回找的具体先行词。
教材中常见的结构是 It is no use/no good + doing sth。
It is worth + doing sth 表示“做某事是值得的”。
It doesn't matter + whether/if + 从句 表示“是否……并不重要”。
It seems/appears that... 和 It is likely/possible/unlikely that... 都可作固定主语结构。
It makes sense + to do sth 表示“做某事是合理的”。
It is a pity/shame that... 表示“令人遗憾的是……”。
| 固定结构 | 含义 | 例句 |
|---|---|---|
| It is no use/no good + doing sth | 做某事没有用 | It is no use arguing with him. |
| It is worth + doing sth | 做某事是值得的 | It is worth visiting the museum. |
| It doesn't matter + whether/if + 从句 | 是否……并不重要 | It doesn't matter whether you agree. |
| It seems/appears that... | 似乎/看起来…… | It seems that nobody knows the answer. |
| It makes sense + to do sth | 做某事是合理的 | It makes sense to back up your files. |
| It is a pity/shame that... | 令人遗憾的是…… | It is a pity that she missed the chance. |
和他争论没有用。 It is worth visiting the museum twice.
值得去参观这座博物馆两次。 It doesn't matter whether you agree with us.
你是否同意我们并不重要。 It makes sense to review the text before the exam.
考试前复习课文是合理的。
强调句与主语从句、定语从句的判定
判断含 It is/was...that... 的句子时,不能只凭 it 和 that 的形式下结论。
形式主语句中的 that 从句是真正主语,如 It is clear that...。
强调句去掉 It is/was 和 that/who 后,剩余部分能直接表达完整意思。
定语从句中的 who/that 用于限定前面的名词,删除后会丢失必要信息。
若 that 在 It is/was 后充当连接词而不是关系词,通常属于形式主语句。
强调人作主语时常用 who 或 that,强调其他成分通常用 that。
| 结构 | 删除框架后的结果 | 结论 |
|---|---|---|
| It was John that called. | John called. | 强调句 |
| It is clear that he left. | clear that he left. | 形式主语句 |
| The boy who called is my brother. | The boy is my brother. | 定语从句,删除后信息受损 |
| The book that I bought is useful. | The book is useful. | 定语从句,删除后信息受损 |
我正是在图书馆遇见他的。 It is obvious that he was right.
显然,他是对的。 The student who won the prize is my cousin.
赢得奖品的学生是我表弟。 This is the book that I recommended.
这就是我推荐的那本书。
📌 北京真题 2 题原卷原题,答案按官方解析;单项填空 1 题;语法填空 1 空
Being a parent is not always easy, and being the parent of a child with special needs often carries with extra stress.
A. itB. themC. oneD. him
看答案
✅ A. it(it 指代前面整件事)
观察句子结构,主语是动名词短语 being the parent...,谓语是 carries。这里考查固定搭配 carry with it,其中 it 指代前面提到的“成为特殊需求儿童的父母”这件事,意为“随之带来”。由于主语是单数概念,故选 it。最易误选 B,因为它试图指代 parents,但本句主语是“成为父母”这一行为而非父母个体。
It takes them hundreds of years (break) down.
看答案
✅ to break(It takes +时间+ to do)
It takes + 时间 + to do 为固定句型,it 是形式主语。
⚠️ 易错点
- it 既可能有指代,也可能只占位置,必须向前找对象、向后找真正内容。
- 表示某人做某事用 for sb to do;评价某人善良等品质常用 of sb,不能只凭中文‘对某人’选介词。
- find it easy to do 中 it 应保留,不能写 find easy to do 来表达完整的该结构。
- It takes 的时间后接 to do,不能套成 doing。
- This is the first time that… 通常接现在完成时,不要只因 first 就用一般过去时。
- It will be…before 从句谈将来通常用一般现在时,不能机械加 will。
- It was ten when he arrived 说明到达时十点;强调 at ten 要写 It was at ten that he arrived。

• 单数可数名词:What + a/an + 形容词 + 名词 + 主谓!
• 复数或不可数名词:What + 形容词 + 名词 + 主谓!
• 冠词取决于名词的数和可数性,不看形容词。

Make sure you fill in the attendance sheet at each session to record your attendance.
本句以“Make sure...”开头,主句省略了主语 you,由动词原形引导,构成了典型的祈使句,用于表达要求。其中 sure 后接了一个省略 that 的宾语从句(you fill in...)来具体说明确保的内容,句末的 to record... 为不定式短语作目的状语。全句意为:请确保你在每次活动中都填写签到表,以记录你的出勤情况。
祈使句加 and、or
祈使句 + and/or + 陈述句,表示“条件 → 结果”。
• 祈使句 + and → 按要求做,就得到某结果
• 祈使句 + or/otherwise → 不这样做,就会有另一结果
• 例外:前项可用名词短语(如 One more effort, and...)

反意疑问句的基本对应
反意疑问句核心:前肯后否,前否后肯。
• 附问助动词、时态与陈述部分对应。
• 主语换成人称代词。例外:there be 结构保留 there。
• 否定陈述的回答:Yes 表示事实肯定,No 表示事实否定。
| 陈述部分 | 附问形式 | 例句 |
|---|---|---|
| be 动词 | 同一 be 动词 + not | She is busy, isn't she? |
| 完成时 | 保留 have/has/had | They have left, haven't they? |
| 一般现在时或一般过去时的实义动词 | do/does/did + not | You work here, don't you? |
| 情态动词 | 保留原情态动词 | He can swim, can't he? |
| there be | 保留 there | There is a problem, isn't there? |
| 问题 | 答 Yes 的条件 | 答 No 的条件 |
|---|---|---|
| You know him, don't you? | 确实认识:Yes, I do. | 不认识:No, I don't. |

“Well, it’s pretty awesome, isn’t it?” he replied.
本句中的“it’s pretty awesome, isn’t it?”体现了反意疑问句的基本对应。其结构为“前肯后否”:陈述部分使用肯定形式 it is,则随后的附问部分需使用否定形式 isn't it,且助动词 is 与主语 it 保持一致。全句意思是:“嗯,这太棒了,不是吗?”
附问中的易错情况
附问形式与主句肯定/否定意义相反。
• never, hardly, seldom, little, few 为否定,附问用肯定。
• a little, a few 为肯定,附问用否定。
• unhappy, dislike 等否定词缀不计入句子否定。
• I am... 附问用 aren't I。
• Let's... 附问用 shall we。
• 普通祈使句附问用 will you;肯定祈使句可随语气变化,will you 不是唯一形式。
• I think/believe... 等第一人称现在时主句,附问针对宾语从句。
• I don't think... 的否定计入,附问用肯定。
| 陈述部分信号 | 整句语法极性 | 附问 |
|---|---|---|
| never/hardly/scarcely/seldom/rarely | 否定意义 | 肯定形式 |
| little/few | 否定意义 | 肯定形式 |
| a little/a few | 肯定意义 | 否定形式 |
| unhappy/dislike 等 | 通常不视为语法否定 | 否定形式 |
| I'm... / Let's... | 特殊结构 | aren't I? / shall we? |
| I think... / I don't think... | 附问针对从句 | 按从句极性或主句极性处理 |

时间不多了,是吗? I'm next, aren't I?
下一个轮到我了,是吗? I think she is ready, isn't she?
我认为她准备好了,对吗? I don't think he is ready, is he?
我认为他还没准备好,对吗?
so、such 的程度与结果
so/such...that... 表示“如此……以至于……”。
• so + 形容词/副词 + that 从句
• such + (a/an) + 形容词 + 名词 + that 从句
• 表数量的 many/much/few/little 用 so(如 so many books)
• 例外:little 表“小的”用 such(如 such a little child)
• so + 形容词 + a/an + 单数可数名词(如 so difficult a task)
• that 在口语中可省略,正式写作宜写清
| 修饰对象 | so 结构 | such 结构 |
|---|---|---|
| 形容词或副词 | so tired / so quickly | 不直接用于单独修饰形容词或副词 |
| 普通名词短语 | so useful a tool | such a useful tool / such useful tools |
| 数量 | so much work / so few errors | 不用于 many/much/few/little 的数量意义 |
| 单数可数名词 | so difficult a task | such a difficult task |
| 词 | 意义 | 正确结构 |
|---|---|---|
| little | 数量少 | so little time |
| little | 年龄小或体积小 | such a little child |

她犯了太多错误,只好重写那篇文章。 It was so difficult a task that no one finished it on time.
那是一项如此困难的任务,以致没人按时完成。
there be 与 have、has、acquire 的区别
there be 的主语是存在的事物本身,强调“存在/出现”。
have/has 的主语是拥有者,强调“拥有、具有”,也可表示经历、关系或疾病。
acquire 是及物动词,表示“获得、习得”,必须带宾语,不用于表达某处存在某物。
have/has 作实义动词时随主语变化,作完成时助动词时用 have/has/had。
汉语“有”可能对应 there be 或 have/has,必须先辨句意和主语。
| 结构 | 核心语义 | 例句 |
|---|---|---|
| there is/are | 某处有某物存在 | There are two apples in the basket. |
| has/have | 某人拥有或具有 | He has two apples in the basket. |
| has/have been to | 去过某地,具有某种经历 | She has been to Beijing several times. |
| acquire | 获得、习得某物或技能 | The laboratory acquired a new instrument. |
| 常见搭配 | 含义或用法 | 例句 |
|---|---|---|
| There is no doubt that... | 毫无疑问 | There is no doubt that practice matters. |
| There is no need to do... | 没有必要做…… | There is no need to panic. |
| There is a chance/possibility of doing... | 有……的可能 | There is a possibility of further talks. |
| There is a difference between A and B | A 与 B 有差别 | There is a difference between age and experience. |

他的篮子里有两个苹果。 She has been to Beijing several times.
她去过北京好几次。 The laboratory acquired a new instrument.
实验室购置了一台新仪器。
there be 各时态与情态标志词速查
there be 的时态由 be 承担,there 本身没有数和时态变化。
高考中独立存在句最常用一般现在时、一般过去时、一般将来时和完成时,也常见情态结构。
进行体和完成进行体在 there be 独立存在句中不常作标准谓语,There is/are someone doing sth. 通常应分析为 there be + doing 后置修饰。
判断时先圈出 be 及其后的完整形式,再结合时间状语和语境确定时态。
since、for、so far、by the time 等可提示完成时,但时间状语不能脱离语境机械判断。
| 时态 | be 的形式 | there be 形式与高考提示 | 例句或说明 |
|---|---|---|---|
| 一般现在时 | is/are | There is/are...,最常用 | There is a need for change. |
| 一般过去时 | was/were | There was/were... | There were two entrances. |
| 一般将来时 | will/shall be | There will be... | There will be a trial next month. |
| 过去将来时 | would be | There would be... | There would be no easy answer. |
| 现在完成时 | has/have been | There has/have been... | There have been several changes. |
| 过去完成时 | had been | There had been... | There had been no warning. |
| 将来完成时 | will have been | There will have been... | There will have been many changes by then. |
| 情态结构 | can/could/may/might/must/should/would + be | There may/must be... | There must be a problem. |
| 时态或结构 | 常见时间信号词 | 使用提醒 |
|---|---|---|
| 一般现在时 | now, at present, currently, these days | 结合语境判断 |
| 一般过去时 | yesterday, ago, last week/year, in 2020 | in 后接年份还需看语境 |
| 一般将来时 | tomorrow, next week/year, soon, in three days | in + 时间段可指过去或将来 |
| 现在完成时 | since, for, so far, up to now, recently | 常与 already、yet、ever、never 连用 |
| 过去完成时 | before, prior to, by the time... | 常表示“过去的过去” |
| 将来完成时 | by + 将来时间 | 例如 by the end of next year |
还有进一步讨论的必要。 There were two serious problems with the design.
这个设计有两个严重问题。 There will be an opportunity for students to ask questions.
届时将有机会让学生提问。 There have been many changes since the new policy was introduced.
新政策实施以来发生了许多变化。 There had been no warning before the accident happened.
事故发生前没有任何警告。
感叹句与一般疑问句、特殊疑问句的转换
感叹句改写为疑问句时,先确定要保留的信息:询问事实用 be 或 do/does/did,询问对象用 what/which,询问方式用 how。
由 What 引导的感叹句强调名词,改为特殊疑问句时常用 What/Which/Whose + 名词 + 助动词结构。
由 How 引导的感叹句强调形容词或副词,改为特殊疑问句时可保留 How + 形容词/副词。
感叹句改为一般疑问句时,形容词通常变成表语,副词通常放在实义动词之后。
so/such 引导的结果状语从句常可改写为 what 或 how 感叹句,但改写时可能增删信息。
| 原感叹句 | 疑问句改写 | 转换要点 |
|---|---|---|
| What an inspiring speech she gave! | Was the speech inspiring? / What speech did she give? | 问事实或问对象 |
| What useful advice you gave! | Was the advice useful? / What useful advice did you give? | advice 为不可数名词 |
| How carefully the volunteers checked every label! | Did the volunteers check every label carefully? | 副词移到动词之后 |
| How bright the stars look tonight! | Are the stars bright tonight? | 形容词作表语 |
她作了一场多么鼓舞人心的演讲啊!→ 她的演讲鼓舞人心吗? What useful advice you gave! → What useful advice did you give?
你给出了多么有用的建议啊!→ 你给出了什么有用的建议? How carefully the volunteers checked every label! → Did the volunteers check every label carefully?
志愿者们核对每张标签时多么仔细啊!→ 志愿者们仔细核对了每张标签吗? How bright the stars look tonight! → Are the stars bright tonight?
今晚的星星看起来多么明亮啊!→ 今晚的星星明亮吗?
祈使句常见搭配与句型
Let's + 动词原形 通常表示“让我们一起……”,Let us + 动词原形 语气较正式。
Let + 第三人称宾语 + 动词原形 表示“让某人做某事”的建议或要求。
Why not + 动词原形? 是提出建议的常用句型。
How about/What about + doing sth? 用于提出或讨论计划。
Would you mind + doing sth? 表示礼貌请求,Would you like to do sth? 常表示邀请或提供帮助。
表示请求或建议的疑问形式在功能上近似祈使句,但句法上仍是疑问句。
remember/forget 接 to do 与 doing 含义不同,祈使句中 Remember to do... 通常指提醒未来的待办事项。
| 结构 | 功能 | 例句 |
|---|---|---|
| Let's + 动词原形 | 建议 speaker 一起行动 | Let's work together. |
| Let us + 动词原形 | 正式地建议或提议 | Let us begin now. |
| Let + 宾语 + 动词原形 | 建议或要求某人行动 | Let him try again. |

| How about/What about + doing? | 讨论或提出计划 | How about meeting at eight? |
| Would you mind + doing? | 礼貌请求 | Would you mind opening the window? |
| Remember to do | 提醒未来的待办事项 | Remember to submit the form. |
我们作出决定前先讨论一下这个问题吧。 Let him have another try.
让他再试一次吧。 Why not ask your teacher for some advice?
为什么不向老师请教一下呢? How about meeting at the school gate?
在学校门口见面怎么样? Remember to submit the form before Friday.
记得在周五前提交表格。
反意疑问句的时态、助动词对照
附问原则上复用陈述部分的 be、助动词或情态动词。
陈述部分没有可复用的助动词时,简单时态用 do/does/did。
have/has/had 若构成完成时,附问保留 have/has/had,若 have 是实义动词,附问用 do/does/did。
情态动词后加 n't,并常缩写成 can't、won't、mustn't、shouldn't 等。
附问主语使用代词,be 动词和 there 通常保留原形式。
| 陈述部分 | 附问形式 | 例句 |
|---|---|---|

📌 北京真题 3 题原卷原题,答案按官方解析;单项填空 3 题
at the door before you enter my room, please.
A. KnockB. KnockingC. KnockedD. To knock
看答案
✅ A. Knock(祈使句谓语动词形式)
观察句子结构,空格后紧跟状语 at the door,且句末有 please,这明显是一个表达请求或命令的祈使句。祈使句的谓语动词必须使用动词原形,因此选择 Knock。很多同学容易误选 B 选项 Knocking,因为习惯性地将句首单词视为非谓语动词作状语,但本句缺乏主句主语和谓语,不能构成完整句子。
carefully if any change occurs when doing experiments in the lab..
A. ObserveB. To observeC. ObservedD. Observing
看答案
✅ A. Observe(祈使句谓语动词)
观察句子结构,发现该句没有主语,且句末是句号,这是一个典型的祈使句。祈使句用于表达命令、请求或建议,谓语动词必须使用动词原形,因此选择 Observe。注意,Doing 等非谓语形式不能单独作谓语,因此 D 选项 Observing 错误。
In any unsafe situation, simply the button and a highly- trained agent will get you the help you need.
A. pressB. to pressC. pressingD. pressed
看答案
✅ A. press(祈使句)
观察句子结构,逗号后是一个完整的句子,而前半部分由 simply 修饰,且后面紧跟 and 连接结果,这是典型的“祈使句 + and + 将来时”结构,意为“只要……就……”。因此此处需用动词原形 press 引导祈使句。最容易误选 C,因为学生常将其误认为是非谓语动词作主语,但若用 pressing,则句子缺乏谓语且与 and 后的结构不匹配。
⚠️ 易错点
- 存在句用 there be,不要把‘有’一律翻成 there have。
- There are people waiting 中 are 是谓语,waiting 修饰 people,不能误填另一个限定动词。
- advice、news 等不可数名词前不能加 a;感叹时用 What useful advice…。
- How carefully she works! 后面是陈述语序,不能套成 does she work。
- 否定祈使句用 Don't be late,不能写 Not be late。
- 反意疑问句须连同 never、few 等词判断肯否;否定前缀则不自动触发肯定附问。
- so little time 的 little 是‘少’,such a little boy 的 little 是‘小’,两者不能混用。
✏️ 自测 5 题
- 用 be 的一般现在时形式填空:There ____ two keys in the drawer.
看答案
✅ are 存在句的主语 two keys 为复数。
- 填 What 或 How:____ valuable information you have collected!
看答案
✅ What 中心是不可数名词 information,用 What,不加冠词。
- 改为否定祈使句:Touch the screen.
看答案
✅ Don't touch the screen. 在动词原形前加 Don't。
- 补全附问:She has never been abroad, ____?
看答案
✅ has she never 使前半句为否定,附问用肯定 has she。
- 填 so 或 such:We had ____ little time that we skipped lunch.
看答案
✅ so little 表示时间少,数量结构用 so little。
五、构词与长难句
词性转换靠构词法,读阅读靠拆长难句
22 构词法先用句法定词性,再用词根词缀与语境定词形。
📝 北京怎么考:北京语法填空会考词性转换,例如2025年第11题 peace→peaceful、2026年第12题 embarrass→embarrassment。阅读还可用词缀辅助猜词,但猜测必须回到语境核验。本章收录北京卷语法填空 3 空(2024—2026 年中的 3 年)。
三种构词方式与屈折变化
构词法分为造新词(派生、合成、转化)与变形式(屈折变化)。
• 派生:词基前后加词缀,如 happy→unhappy/happiness。
• 合成:词组合成新词,如 class+room→classroom。
• 转化:词形不变,词性或用法改变,如 email 作名词或动词。
• 屈折变化:名词复数、动词过去式等语法变化。例外:带 -s/-ed 的词不一定是派生新词。
| 方式 | 例子 | 判断重点 |
|---|---|---|
| 派生 | care→careful | 增加词缀,词义或词性发生变化 |
| 合成 | book+shop→bookshop | 组合成一个词汇单位 |
| 转化 | email(名词/动词) | 词形不变,句法功能改变 |
| 屈折 | work→worked | 表示时态等语法信息 |
核对电子邮箱地址后,我们给组织者发了邮件。 The new bookshop near our school sells dictionaries and stationery.
我们学校附近的新书店出售词典和文具。 His careful answer solved the problem immediately.
他周密的回答立即解决了问题。 The children cleaned the classroom and put the books on the shelves.
孩子们打扫了教室,并把书放到了书架上。
常用前缀:否定与反向
前缀通常改变意义,不一定改变词性。
• un-、in-/im-/il-/ir-、dis-、non- 常与否定有关。
• un-、dis- 在某些动词中表示解除、反向(如 unlock, disconnect)。
• 拼写变体按具体词记,不可随意选择前缀。
• 例外:invaluable 表示“极宝贵的”,非“没有价值”。
| 前缀 | 常见含义 | 例词 |
|---|---|---|
| un- | 不;解除或反向 | unfair;unlock |
| in-/im-/il-/ir- | 不,词形因词而定 | inactive;impossible;illegal;irregular |
| dis- | 不;相反或分离 | disagree;disconnect |
| non- | 非;不属于 | non-smoker;non-fiction |
| 拼写变体 | 常见用法 | 例子 |
|---|---|---|
| in- | 多用于 b、m、p 之前 | inactive;incorrect |
| im- | 常用于 m、p 之前 | impossible;impatient |
| il- | 用于 l 之前 | illegal;illogical |
| ir- | 用于 r 之前 | irregular;irresponsible |
没有合适的工具,不可能完成修理。 The decision was unfair because one student was not given enough time.
这个决定不公平,因为有一个学生没有得到足够的时间。 The two sides disagreed about the best solution.
双方对最佳解决方案意见不一致。 She is a non-smoker and has never used tobacco.
她不吸烟,也从未使用过烟草。 The door was unlocked so that everyone could enter.
门被解除了锁定,以便所有人进入。
常用前缀:时间、数量与关系
前缀是猜词的核心线索,决定词义方向。
• re-:再次、重新
• pre-:在先
• post-:之后
• mis-:错误地
• over- / under-:过度 / 不足,或与位置有关
• inter-:相互、在……之间
• multi-:多
• 判断:结合整词用法确认是否由可拆前缀构成
| 前缀 | 意义线索 | 例词 |
|---|---|---|
| re- | 重新;再次 | rewrite;rebuild |
| pre-/post- | 之前/之后 | prewar;postwar |
| mis- | 错误地 | misunderstand;misspell |
| over-/under- | 过度/不足 | overestimate;underestimate |
| inter-/multi- | 之间/多 | international;multicultural |
| anti- | 反对;抵抗 | anti-smoking |
| co-/semi- | 共同/一半 | cooperate;semicircle |
我们误解了数据,所以重写了报告。 The museum reopened after the postwar reconstruction.
战后重建完成后,博物馆重新开放了。 We had underestimated how long the journey would take.
我们低估了这段旅程所需的时间。 Beijing is a multicultural city where people from many countries live.
北京是一座多元文化城市,许多国家的人居住在这里。 The school launched an anti-smoking campaign last week.
学校上周发起了一项禁烟宣传活动。
名词后缀
名词后缀是判断词性的线索,但不能直接决定可数性或复数。
• -tion/-sion, -ment, -ness, -ity:表示行为、状态或性质
• -er/-or, -ist:表示人或从事活动者
• -er:也可表示工具
• 词根可能变形:如 decide→decision, able→ability,需连同拼写记忆
| 后缀 | 例词 | 提醒 |
|---|---|---|
| -tion/-sion | education;decision | 注意词基和拼写变化 |
| -ment | development;achievement | 具体可数性看词义 |
| -ness | kindness;happiness | 常把 y 改为 i |
| -ity | activity;responsibility | 拼写和重音可能变化 |
| -er/-or/-ist | teacher;visitor;scientist | 常指人、职业或活动者 |
| -er | screwdriver;printer | 也可指工具或设备 |
| 常见不可数名词 | 常见搭配或计数方式 |
|---|---|
| advice | give some advice;a piece of advice |
| information | obtain some information;a piece of information |
| equipment | use some equipment;a piece of equipment |
| progress | make progress |
| research | conduct research;a research project |
她的解释消除了误会。 The decision was made after a careful discussion.
经过认真讨论后作出了这个决定。 The development of the new technology took several years.
这项新技术的开发用了数年时间。 Two scientists from different countries joined the project.
来自不同国家的两位科学家加入了该项目。 A screwdriver is a useful tool for repairing the chair.
螺丝刀是修理椅子的一件有用工具。
形容词后缀与分词形容词
后缀与分词可构成形容词,整词意义须核对。
• -ful:充满/具有
• -less:缺少
• -ous:具有某性质
• -al:与……有关
• -ive:有某作用或倾向
• -able/-ible:可……的
• -ed:表感到(如 interested)
• -ing:表引起(如 interesting)
• 例外:并非所有 -ed 结尾都是形容词
| 后缀 | 例词 | 常见含义 |
|---|---|---|
| -ful/-less | hopeful;hopeless | 充满希望的/无望的 |
| -ous/-al | dangerous;cultural | 危险的/与……有关的 |
| -ive | creative | 有创造力的 |
| -able/-ible | readable;accessible | 可读的/可获得的 |
| -ed/-ing | interested;interesting | 人的感受/事物的性质 |
| 情感或状态 | -ed 形式 | -ing 形式 |
|---|---|---|
| 使感兴趣 | interested | interesting |
| 使兴奋 | excited | exciting |
| 使厌烦 | bored | boring |
| 使疲倦 | tired | tiring |
| 使吃惊 | surprised | surprising |
导游给了我们实用而可靠的建议。 The children were excited about the school trip.
孩子们对这次校游感到兴奋。 The story is so interesting that all the children want to read it.
这个故事非常有趣,所有孩子都想读它。 A broken window was found near the playground.
在操场附近发现了一扇破窗户。 Setting a clear goal is the first step towards achieving it.
设定明确的目标是实现目标的第一步。
副词与动词后缀
后缀决定词性:-ly 构副词,-en/-ise/-ize/-ify 构动词。
• 形容词 + -ly → 方式或程度副词(如 carefully)。
• 例外:friendly, lovely, lonely, lively 是形容词。
• -en, -ise/-ize, -ify → 动词(如 widen, modernize, simplify)。
• 英美拼写差异需保持一致。
• 并非所有单词都能自由加这些后缀。
| 形式 | 例子 | 说明 |
|---|---|---|
| 形容词+-ly | careful→carefully | 常修饰动词或整句 |
| 形容词+-ly | happy→happily | 常把 y 改为 i |
| 同形词 | fast;hard;late | 作副词时词形不变 |
| 形容词+-en | wide→widen | 表示扩大、加长或加强 |
| 形容词+-ise/-ize | modern→modernise | 英美拼写有差异 |
| 形容词+-ify | simple→simplify | 常使动作或性质更明确 |

学生们努力工作,按时完成了任务。 The project aims to widen access to education.
这个项目旨在扩大获得教育的机会。 The company will modernise its old computer systems.
公司将对其旧计算机系统进行现代化改造。
派生时的拼写变化
派生词拼写核心:看 y 前面是什么字母。
• 辅音 + y → 改 y 为 i(如 happy → happiness/happily)
• 元音 + y → 保留 y(如 joy → joyful)
• -le 形容词 → 副词:去 e 加 y(如 simple → simply)
• 例外:true → truly
• 注意:动词加 -ing 的规则不可套用到所有派生词,必须核对具体词。
| 原词 | 派生词 | 易错处 |
|---|---|---|
| happy | happiness;happily | y→i |
| joy | joyful;joyfully | 保留 y |
| simple | simply | 不是 simplely |
| true | truly | 去 e 加 y |
| whole | wholly | 特殊拼写 |
| success | successful;successfully | 保留双 c、双 s |
| wide | widely;widen | 副词与动词形式不同 |

我们在公园度过了一个愉快的下午。 The results were successful, and the team completed the work successfully.
结果很成功,团队也成功地完成了工作。 It is truly necessary to review the lesson before the exam.
考试前复习功课确实很有必要。
合成词与词性转化
合成词形式多样,数词定语不加s,词性由位置决定。
• 形式:连写、带连字符或分写,依词汇习惯而定。
• 数词+名词作定语:名词用单数,如 a five-minute break。
• 非定语情况:名词用复数,如 five minutes。
• 转化词词性:由所在位置判断,如 a daily record 中 record 是名词,record the result 中是动词。
| 类型 | 例子 | 判断重点 |
|---|---|---|
| 名词性合成词 | bookshop | 两个词合为一个名词 |
| 形容词性合成词 | decision-making | 连字符或分写依词汇而定 |
| 开放式复合词 | data analysis | 各部分保留独立词形 |
| 词性转化 | 由所在位置判断词性 | |
| 数词复合定语 | a ten-minute break | 单位名词用单数 |
| 复合定语 | 普通数量表达 | 说明 |
|---|---|---|
| a three-hour trip | The trip lasted three hours. | hour 用单数 |
| a two-week holiday | The holiday lasted two weeks. | week 用单数 |
| a 20-kilometre journey | The journey was 20 kilometres long. | kilometre 用单数 |

语法填空四步定形
语法填空四步定形法:骨架 → 词性 → 语义 → 形式
• 第一步:找句子骨架,确定空格是谓语还是其他成分
• 第二步:按位置和搭配定词性(名词作主宾语,形容词作表语或定语,副词修饰动词、形容词或整句)
• 第三步:结合语义决定肯否和具体词
• 第四步:检查名词单复数、动词时态语态及拼写
• 例外:位置非充分条件,the后可先有形容词,be后可接名词、分词或介词短语
| 句子位置 | 常见词性 | 例词或结构 |
|---|---|---|
| a/the+空格 | 名词或形容词 | a book;the useful book |
| 空格+名词 | 形容词或分词形容词 | a broken window |
| be/feel/seem+空格 | 形容词、名词或分词结构 | be interested;be a teacher |
| very/quite+空格 | 形容词 | very careful |
| 空格+at/on/in | 形容词或介词短语 | good at;responsible for |
| 空格+to+动词原形 | 不定式结构 | want to do;manage to do |

| have/has提示 | 时态和过去分词 | have finished;have been doing |
| by提示 | 完成时态 | by then;by the end of last year |
| not only提示 | 并列成分的词性和结构 | not only…but also |

- 动词后的介词常由语义决定,如 depend on 表示依靠,result in 表示导致。
- 名词和形容词后的介词也常固定,如 access to、good at、responsible for。
- 动词后接 doing 或 to do 要根据具体动词判断,如 enjoy doing、want to do。
- look forward to、be used to中的 to 是介词,因此后接 doing。
- suggest、advise等动词不接“宾语+to do”结构。

23 长难句拆解找谓语、圈主干、分层级,再把修饰放回去。
📝 北京怎么考:北京阅读理解、七选五、阅读表达都需要识别复杂句。阅读时据主干理解逻辑,作文中用同一方法检查句子是否完整。
第一步:找限定谓语与主干
找限定谓语(带时态/情态)及其对应主语,锁定主干。
• 主干保留:主谓、主谓宾、主系表等必要成分。
• 例外:不定式、分词虽像动词,但非独立谓语。
• 实例(2024阅读C):To facilitate...是目的;we(主)+build(谓)+models(宾)为主干;based on...修饰models;that are...修饰conceptual metaphors。
• 判定:限定谓语有build和are,但are属于定语从句。
• 要求:读懂主干后,必须将目的与修饰成分还原,不可直接删除。
| 成分 | 识别标志 | 处理方式 | 例词或结构 |
|---|---|---|---|
| 主语 | 名词、代词或名词性从句 | 确认它与哪个限定谓语搭配 | we;What the committee proposed |
| 谓语 | 时态、情态或系动词 | 圈出所有限定谓语并配主语 | build;is;was accepted |
| 宾语 | 及物动词之后 | 保留核心意义 | models;the answer |
| 表语 | 系动词之后 | 与主语构成主系表结构 | a rare skill;irresistible |
| 非谓语 | to do、doing、done | 不另算主句谓语,判断其依附对象 | To facilitate;based on;imagining |
| 从句谓语 | 从句主语之后 | 暂时括起从句,再找全句主干 | that are familiar to us |
为了帮助我们理解世界,我们依据自己熟悉的概念隐喻来建立模型。 The problem facing the team was solved after a careful review.
团队面对的问题经过认真审查后得到了解决。 Having finished the experiment, the students handed their results to the teacher.
完成实验后,学生们把实验结果交给了老师。 What the committee proposed was accepted after a long discussion.
委员会提出的方案经过长时间讨论后获准。
To facilitate our comprehension of the world, we build models based on conceptual metaphors (隐喻) that are familiar to us.
本句的核心主干是“we build models”。其中 we 是主语,build 是限定谓语,models 是宾语。句首的 To facilitate... 是目的状语,based on... 是后置定语修饰 models,that 引导的从句进一步修饰 metaphors。全句意为:为了方便我们理解世界,我们构建基于熟悉概念的隐喻模型。
第二步:给多层从句划边界
从连接词出发逐层找管辖分句,严禁将所有 that/if 视为同一层。
• 外层结构:If A, B since C(如果 A,则 B,因为 C)。
• 主句主干:reasoning won’t reveal reality either。
• since 用法:表原因,非“自从”。
• 内层结构:C 内部含 that 定语从句。
• that 细节:先行词为并列名词 concepts and words。
| 连接词类型 | 常见信号 | 句法功能 | 必须找到的结构 |
|---|---|---|---|
| 条件 | if;unless;provided that | 条件状语从句 | 从句主语+谓语 |
| 时间 | when;while;before;after;as soon as | 时间状语从句 | 从句主语+谓语 |
| 原因 | because;since;as | 原因状语从句 | 从句主语+谓语 |
| 让步 | although;even if;though | 让步状语从句 | 从句主语+谓语 |
| 目的或结果 | so that;in order that;so...that | 目的或结果状语从句 | 从句主语+谓语 |
| 关系 | who;which;that;whose;where;when | 定语从句 | 先行词+从句主谓 |
| 宾语 | whether;if;that | 宾语从句 | 从句主语+谓语 |
| 边界标记 | 表示 | 示例 |
|---|---|---|
| [If A] | 条件状语从句 | [If A], B |
| [because/since C] | 原因状语从句 | B [because C] |
| [that D] | 定语从句或宾语从句 | 名词 [that D] |
如果实证经验不能揭示现实,推理也不能揭示现实,因为推理依赖的概念和词语取决于我们的社会、文化和心理历史。 Although the proposal seemed promising, the committee rejected it because its estimated cost was far beyond the available budget.
尽管方案看似可行,委员会还是否决了它,因为预计成本远超可用预算。 When the final results arrived, the scientists who had waited for months finally published their conclusions.
最终结果到来时,等了数月的科学家们终于公布了结论。 Before the committee announced its decision, residents had complained that the proposed factory might increase local pollution.
在委员会宣布决定之前,居民们已经抱怨拟建工厂可能增加当地污染。
If empirical (实证的) experience fails to reveal reality, reasoning won’t reveal reality either since it relies on concepts and words that are contingent on our social, cultural and psychological histories.
本句包含三层结构:If 引导的条件状语从句,since 引导的原因状语从句,以及 since 从句内部由 that 引导的定语从句(that are contingent on...)。通过划定边界,可将长句拆解为“条件 → 主句 → 原因 → 定语”的逻辑链条。全句意为:如果实证经验无法揭示现实,那么推理也无法揭示,因为推理依赖于受社会、文化和心理历史制约的概念和词语。
第三步:跨过插入的定语从句
主语和谓语之间可能插入很长的修饰语,需先跳过修饰语找谓语。
• 临时括起两逗号间的 which 从句,将主语 project 接回谓语 survived。
• survived 与 worked 是同一主语的并列谓语。
• which 指代 That project。
• where 引出地点状语从句,意为“在传统方法不奏效之处”。
• 例外:didn't 后省略了 work。
• 最终理解:项目在封锁中继续开展,且解决了传统方法解决不了的问题。
| 位置或信号 | 结构 | 还原步骤 | 注意事项 |
|---|---|---|---|
| 主语与谓语之间 | 名词+which/who 从句+主句谓语 | 括起从句,接回主语和谓语 | 从句谓语不属于主句 |
| 名词后且无逗号 | 限制性定语从句 | 先确定名词所指范围 | 不能随意删去 |
| 名词后且有逗号 | 非限制性定语从句 | 先找主句,再补补充信息 | 通常译作“,这……,它……” |
| which 指代整句 | This is why...;That is what... | 在从句中找整句的概括对象 | which 不一定只指最近名词 |
| where 或 when | 关系副词引导定语从句 | 分别补成 in which、when/which | where 不作句子成分 |
| 关系词 | 在从句中的作用 | 例句 |
|---|---|---|
| who | 主语 | the student who helped us |
| whom | 宾语 | the teacher whom we thanked |
| whose | 所属或所属关系 | the team whose members were experts |
| which/that | 主语或宾语 | the report which/that we read |
| where | 相当于 in which | the city where we lived |
| when | 相当于 when/at which | the year when it happened |
那个我坐在沙发上就能完成、无需忍受沙漠酷热的项目,不仅挺过了封锁,而且在传统方法不奏效之处发挥了作用。 The report, which was written after a nationwide survey, remains the most detailed account of the event.
这份在全国调查后写成的报告仍是关于该事件最详尽的记述。 Students who volunteer for the project will receive extra credit.
自愿参加该项目的学生将获得额外学分。 The team, whose members came from five universities, completed the survey ahead of schedule.
这个团队的成员来自五所大学,他们提前完成了调查。
That project, which I could complete from my sofa instead of in the burning heat of the desert, not only survived the lockdown but worked where traditional methods didn’t.
句中 which I could complete from my sofa instead of in the burning heat of the desert 是非限制性定语从句,作为插入成分修饰主语 That project。分析时应先将其括起,直接连接主语与谓语 not only survived... but worked...。全句意为:那个项目不仅在封锁期间得以延续,且在传统方法失效时依然有效,而且我可以在沙发上而非沙漠酷暑中完成它。
第四步:辨插入语与形式宾语
插入语不占主干成分,形式宾语it不充实含义。
• 插入语:如she wrote later,直接括起剔除。
• 形式宾语:it作形式宾语,hard作宾补,to answer为真正宾语。
• 复杂主语:imagining…—and learning…—共同构成主语内容。
• 定语修饰:that isn’t part of real life修饰something。
• 结构闭环:直到is a rare skill才完成because从句的主系表结构。
| 判断项目 | 插入语 | 形式宾语 it | 处理方法 |
|---|---|---|---|
| 位置 | 常位于句中并被逗号隔开 | 位于及物动词之后 | 分别标出说明语和宾语位置 |
| 能否删除 | 可暂时删除而不破坏主句 | 不能删除,否则句子缺少宾语 | 插入语拿掉后读主干 |
| 后续成分 | 后面不一定接特定结构 | 常接形容词或副词+不定式,也可接 that 从句 | 把 it 替换成后面的内容 |
| 句法作用 | 补充说明,不占主句核心位置 | 占宾语位置但没有实际词汇意义 | 结合全句结构判断 |
| 翻译 | 按补充说明翻译 | 不能只译“它” | 形式宾语要译出所指内容 |
她后来写道,他们觉得这个问题很难回答,因为想象现实生活中尚不存在的事物,并学会把它变成现实,是一种罕见的技能。 The researchers found it necessary to compare the results carefully before drawing any conclusion.
研究人员发现,在得出任何结论前仔细比较结果是必要的。 The experiment made it clear that the proposed method worked better under extreme conditions.
实验清楚表明,提出的方法在极端条件下效果更好。 The fact that the team had solved the problem impressed everyone.
团队已经解决了这个问题这一事实令所有人印象深刻。
They found it hard to answer, she wrote later, because imagining something that isn’t part of real life—and learning how to make it real—is a rare skill.
先把插入语 she wrote later 拿开,主干是 They found it hard to answer。这里的 it 指上文提到的那个问题,是 found 的真宾语,不是形式宾语;hard to answer 作宾语补足语,to answer 补充说明 hard(难在哪:难回答)。because 从句的主语是动名词短语 imagining something…—and learning how to make it real—,谓语是 is。全句意为:她后来写道,他们觉得这个问题很难回答,因为想象现实中不存在的东西并学会把它变成现实,是一种罕见的能力。
第五步:还原倒装再理解
遇句首not only、only+状语、否定词,必须先还原倒装再找主语。
• 不要凭第一个名词判断主语。
• 2012年阅读C前半句还原为:rewarding experiences are remembered better。
• 后半句主语为:negative consequences。
• 两个分句均为被动,not only…but…also…突出压力带来的双重记忆效果。
• 还原语序服务于理解,例外:引用原句时不能自行改写。
| 触发结构 | 倒装示例 | 常规语序 | 判断重点 |
|---|---|---|---|
| not only...but also... | Not only were the results clear. | The results were clear. | not only 位于句首时前一分句倒装 |
| only+状语 | Only then did he leave. | He left only then. | only 后接时间或地点状语 |
| not until | Not until midnight did they stop. | They did not stop until midnight. | 主句用部分倒装 |
| no sooner...than... | No sooner had he arrived than it rained. | He had scarcely arrived when it rained. | had 与主语搭配,than 引出结果 |
| neither/nor | Neither did he answer. | He did not answer either. | neither 或 nor 位于句首 |
| so/such...that... | So excited were the children that they shouted. | The children were so excited that they shouted. | so 或 such 位于句首 |
| rarely 等否定副词 | Rarely does he complain. | He rarely complains. | 副词提前触发倒装 |
不仅有益的经历会被记得更牢,负面后果也更容易被回想起来。 Only when the results were published did we realize how important the experiment was.
只有在结果公布后,我们才意识到实验有多重要。 Not until the police had checked the footage did the manager allow the game to continue.
直到警方查完录像,经理才允许比赛继续。 No sooner had the storm begun than the power failed.
暴风雨刚开始就停电了。 Rarely does such a change occur in a single generation.
这种变化很少在一代人内发生。
Not only are rewarding experiences remembered better, but negative
consequences are also easily recalled.
句中“Not only are rewarding experiences remembered better”体现了部分倒装。因否定词组 Not only 置于句首,be 动词 are 提前至主语 rewarding experiences 之前。还原为陈述语序应为:Rewarding experiences are not only remembered better。全句意为:不仅有回报的经历更容易被记住,负面的后果也容易被回忆起来。
第六步:补回并列中的省略
并列结构中,共同的主语、谓语等成分可省略,阅读时需补回。
• 案例:but much less often to scientists 省略了 it is taught。
• 补全:but it is taught much less often to scientists。
• 指代:it 回指上文“想象并实现新事物的技能”,而非 artists。
• 语法:much 修饰比较级 less,less often 比较教学频率。
• 翻译:译文保留“少得多”,例外:不能改成“从来不”。
| 省略项目 | 常见信号 | 还原示例 | 检查重点 |
|---|---|---|---|
| 主语和谓语 | and/but 后直接出现另一主语或时间状语 | The first arrived..., and the second... | 补回后时态要一致 |
| 谓语 | and so+助动词 | He can sing, and so can I. | 补成 I can sing |
| 宾语 | give/offer 后出现两组对象 | He gave Mary a book and Peter a pen. | 区分直接宾语和间接宾语 |
| 助动词或情态动词 | can/will/must 后接两个动作 | She can swim and dive. | 一个情态动词可支配两个动作 |
| be 动词 | 形容词并列或 so+助动词倒装 | The room was clean and tidy. | 补回后保持主谓一致 |
这种技能会被教授给艺术家和工程师,但教授给科学家的频率要低得多。 She can swim and dive, but her brother cannot swim or dive.
她会游泳和潜水,但她哥哥既不会游泳,也不会潜水。 The teacher gave Mary a book and Peter a pen.
老师给了玛丽一本书,给了彼得一支笔。 The first group arrived on Monday, and the second two days later.
第一组周一到达,第二组两天后到达。 He is interested in science, and so am I.
他喜欢科学,我也喜欢。
It is taught to artists and engineers, but much less often to scientists.
本句在 but 后的分句中省略了重复的主语和谓语,即 "much less often to scientists" 实际上省略了 "it is taught"。结构上,but 连接两个并列成分,后半部分通过省略使句子更简洁。全句意思是:这项技能被教授给艺术家和工程师,但教授给科学家的频率要低得多。
第七步:区分同位语与定语从句
同位语从句说明名词的具体内容,而定语从句修饰名词。
• 结构:The notion (主语) + is (系动词) + irresistible (表语) + to many (对许多人而言)。
• 同位语从句:that we live in someone else’s video game 说明 notion 的具体内容。
• 判断标准:从句本身完整,that 不充当主宾语。
• 例外:that 紧挨名词不一定是定语从句。
• 逻辑:句子判断对象是“这种观念”,而非断言我们活在游戏中。
| 判断维度 | 同位语从句 | 定语从句 |
|---|---|---|
| 作用 | 说明前面概念的具体内容 | 限定或补充前面的人或物 |
| that/which | that 不充当主语或宾语 | 关系词在从句中承担主语、宾语等成分 |
| 常见先行项 | fact、idea、notion、suggestion、news | 人、物、具体事件或代词 |
| 标点 | 常形成插入式说明 | 限制性从句通常不用逗号,非限制性从句用逗号 |
| 检验问题 | “什么内容”或“具体指什么” | “哪一个人”“哪一个”或“什么样的” |
对许多人来说,“我们生活在别人的电子游戏中”这一观念具有难以抗拒的吸引力。 The fact that the road had been closed surprised the drivers.
道路已经封闭这一事实使司机们感到意外。 The report that changed the project’s direction was published last week.
改变了项目方向的那份报告上周发布了。 Her suggestion that we leave early was accepted.
她提出的让我们早点离开的建议被接受了。
The notion that we live in someone else’s video game is irresistible to many.
句中 that 引导的从句 that we live in someone else’s video game 是 notion 的内容补足从句。该从句结构完整,that 仅作为连接词而不充当任何成分,用于具体说明 notion 的含义。全句意思是:我们生活在别人的电子游戏中的这一观念对许多人来说具有不可抗拒的吸引力。
第八步:串回指代和逻辑,用于写作检查
拆解后必须回溯语篇,核对指代、逻辑与作者态度。
• 确认代词所指(如23年阅读C中it指前文对当下的偏向)。
• 明确主干句意(如it translates into...意为“这种偏向表现为不愿……”)。
• 明确否定范围、时间对比及作者态度。
• 识别讨论范围(如on...like...)与目的解释(如to make...)。
• 确保修饰语紧扣对象(如that...修饰sacrifices)。
• 对照时间词(如today与tomorrow)理清逻辑。
• 写作反查:谓语必有主语,分句必有合法连接,代词必可回指,修饰语必紧扣对象。
• 例外:不必为了句长堆叠从句。
| 检查项 | 追问 | 常见错误 | 修正方式 |
|---|---|---|---|
| 主谓关系 | 每个限定谓语对应谁 | 一个分句找不到主语 | 补主语或调整从句边界 |
| 连接关系 | 前后分句是什么逻辑 | 只有逗号而没有连接词 | 补 and、but、because 等 |
| 代词指代 | it、they、this 指什么 | 先行词模糊或单复数不一致 | 靠近原文定位并统一数 |
| 修饰对象 | 分词或定语从句修饰谁 | 机械接到最近的名词 | 按句法和语义确定中心词 |
| 否定范围 | not 否定哪个成分 | 把局部否定译成全句否定 | 圈出被否定的词组 |
| 时间逻辑 | 前后时间怎样对照 | 先后关系或时态矛盾 | 用 before、after、while 等衔接 |
| 表达效率 | 一句是否只有一个中心 | 从句过多且逻辑不清 | 拆句或删去重复修饰 |
而在气候变化这类缓慢发展的问题上,这种偏向表现为:不愿今天作出一些本可在明天带来重大改变的小小牺牲。 The team repeated the experiment three times, but it produced the same result each time.
团队把实验重复了三次,但每次都得到了相同的结果。 Although the early results looked promising, they did not prove that the treatment would work for every patient.
尽管早期结果看起来很有希望,但这些结果并不能证明该疗法对每位患者都有效。 To reduce waste, the company redesigned the packaging, which made the boxes smaller and easier to recycle.
为了减少浪费,公司重新设计了包装,使包装盒更小,也更容易回收。
And on slow-burning problems like climate change, it translates into the unwillingness to make small sacrifices (牺牲) today that could make a major difference tomorrow.
本句核心在于代词 "it" 的指代以及 "today" 与 "tomorrow" 的逻辑对照。结构上,it 为主语,translates into 为谓语,that 引导定语从句修饰 sacrifices,强调这些牺牲在未来的潜在效果。通过串回指代明确 it 的具体含义,并利用时间对比揭示短视心理。全句意为:在气候变化等长期问题上,这种倾向表现为人们不愿在今天做出能为明天带来重大改变的小小牺牲。
补充一:连接词与逻辑关系速查
1. 先判句法位置:连接词后若形成主谓结构,多为状语从句;关系词后形成从句并修饰名词,多为定语从句。
2. 从属连词表示逻辑关系:if、because、although、when、so that 等分别引出条件、原因、让步、时间和目的等分句。
3. 并列连词连接同级成分:and、but、or、so、yet 连接词、短语或分句,不能仅凭中文词义决定结构。
4. 关系词连接修饰成分:who、which、that、whose、where、when 引导定语从句,关系词在从句中承担成分或连接作用。
5. that 的身份要看位置和功能:that 可引导宾语从句、同位语从句或定语从句,判断依据是它是否在从句中充当成分。
6. since 常常兼有两义:可表示“自从”,也可表示“由于”,要根据从句内容和时间关系判断。
7. 语义关系优先:连接词只是线索,最终仍要判断作者表达的是条件、转折、因果、递进还是对比。
| 逻辑关系 | 常见连接词 | 典型结构 | 理解提示 |
|---|---|---|---|
| 时间 | when;while;before;after;as soon as | 连接词+完整分句 | 判断动作先后或同时 |
| 条件 | if;unless;as long as;provided that | 条件分句+主句 | 常可译为“如果……就……” |
| 原因 | because;since;as | 原因分句+主句 | 回答“为什么” |
| 让步 | although;even if;though | 让步分句+主句 | “虽然……但是……” |
| 目的 | so that;in order that | 主句+目的分句 | 回答“为了什么” |
| 结果 | so...that;such...that | 主句+结果分句 | 回答“产生了什么结果” |
| 比较 | as...as;not as...as;than;the more...the more | 比较双方+相同结构 | 注意比较对象和程度 |
| 并列 | and;but;or;so;yet;nor | 同级成分或同级分句 | 检查前后是否对称 |
| 修饰 | who;which;that;whose;where;when | 先行词+关系词+从句 | 找关系词在从句中的作用 |
| 宾语 | whether;if;that | 动词+宾语从句 | 从句必须能独立回答主语和谓语 |
尽管这个计划看起来简单,但它还是失败了,因为团队低估了测试所需的时间。 When the deadline arrived, the manager decided to postpone the launch until all safety checks were complete.
截止日期到来时,经理决定推迟发布,直到所有安全检查完成。 The teacher explained the rule so clearly that every student could apply it.
老师把规则解释得非常清楚,以至于每个学生都能应用它。 He said that the results were reliable, although the sample was relatively small.
他说结果是可靠的,尽管样本量相对较小。
补充二:分词、介词短语与从句边界
1. 先找限定谓语:没有限定谓语的结构通常不是完整主句。
2. 分词短语不是独立分句:现在分词和过去分词短语要依附于主语、宾语或全句。
3. 分词要有逻辑主语:分词动作的执行者通常与主句主语一致,否则可能构成悬垂分词。
4. 过去分词看被动关系:过去分词修饰宾语时通常表示被动,如 written by、covered in。
5. 不定式按功能判断:to do 可作目的、状语、宾语、定语或主补语,不能一律译成“为了”。
6. 动名词可作主语或宾语:动名词短语仍由内部动词承担意义,不属于句子的限定谓语。
7. 介词短语从介词起笔:介词后的名词、代词或动名词属于介词宾语,宾语从句则可整体充当介词宾语。
8. 从句可以嵌套在短语中:如 interested in what he said 中,what he said 是介词 in 的宾语。
| 结构 | 常见标志 | 是否为限定谓语 | 判断问题 |
|---|---|---|---|
| 不定式短语 | to do | 否 | 作目的、状语、宾语、定语还是主补语 |
| 动名词短语 | doing | 否 | 作主语、宾语还是介词宾语 |
| 现在分词短语 | doing,逻辑主语通常主动 | 否 | 谁正在做这个动作 |
| 过去分词短语 | done,逻辑主语通常被动 | 否 | 谁承受了这个动作 |
| 介词短语 | in、on、for、with、by 等+名词或 doing | 否 | 介词管辖到哪个成分 |
| 宾语从句 | what、whether、that 等引导 | 从句内部有谓语 | 从句能否回答主语和谓语 |
| 定语从句 | who、which、that、whose、where、when | 从句内部有谓语 | 先行词是什么,关系词作何成分 |
站在窗边,她看着外面的大雨。 The report, written by three independent researchers, was widely cited.
这份由三名独立研究员撰写的报告被广泛引用。 I was interested in what the teacher had said about online learning.
我对老师关于在线学习所说的话很感兴趣。 He remained silent because he did not know how to answer the question.
他保持沉默,因为他不知道该如何回答这个问题。
补充三:常见搭配一览
1. 把搭配当作整体记忆:介词不能随意替换,固定搭配应与中心词一起背。
2. 先找中心词:语法填空先看空格前是名词、形容词还是动词,再决定所需搭配。
3. 注意后接形式:介词后接名词、动名词或从句时要分别判断,不能看到 to 就填动词原形。
4. 区分逻辑方向:result in 表示“导致”,result from 表示“由……导致”;base on 表示“依据”,be based on 表示“以……为依据”。
5. 区分固定结构:used to do 表示“过去常常”,be used to doing 表示“习惯于”。
6. 关注同义替换:阅读中 based on、rely on、depend on 和 be contingent on 都可能表示“依靠、依据”。
7. 语境决定最终形式:搭配提供高频框架,宾语性质、时态和主谓一致仍要结合句子判断。
| 语义 | 高频搭配 | 常见后接成分 | 结构示例 |
|---|---|---|---|
| 依据,依靠 | be based on;rely on;depend on;be contingent on | 名词/动名词/that 从句 | be based on evidence |
| 为……所熟悉 | be familiar to sb. | 人称代词或名词 | The idea is familiar to us. |

| 适用于 | apply to | 名词 | The rule applies to students. |
| 适应 | adapt to | 名词/动名词 | adapt to working remotely |
| 由……组成 | consist of | 名词 | The team consists of ten members. |
| 转化为 | translate into | 名词 | translate into action |
| 防止 | prevent sb. from doing sth. | 动名词 | prevent them from leaving |
| 提醒 | remind sb. of sth. | 名词/动名词 | remind us of the risk |
| 解释,占比 | account for | 名词/动名词 | account for the difference |
| 不同于 | differ from;be different from | 名词 | differ from the original |
| 易混结构 | 区别 | 例句 |
|---|---|---|
| used to do/be used to doing | 前者表示过去常常,后者表示习惯于 | He used to smoke;He is used to smoking. |
| look forward to doing | to 是介词,后接动名词 | We look forward to hearing from you. |
| devote oneself to doing | to 是介词,后接动名词 | She devoted herself to helping others. |
| be opposed to doing | 表示反对某事或做法 | They were opposed to closing the factory. |
| object to doing | 表示反对,后接动名词 | She objected to changing the plan. |
| result in/result from | 前者是“导致”,后者是“源于” | The policy resulted in change;The change resulted from the policy. |
根据五年间收集的数据,团队修改了最初的模型。 The new policy is likely to reduce both costs and emissions.
新政策很可能同时降低成本和排放。 She devoted herself to helping children in remote areas.
她全身心投入帮助偏远地区的儿童。 The policy resulted in a sharp rise in applications, while its success resulted from years of public consultation.
该政策导致申请数量大幅上升,而它的成功则源于多年的公众咨询。
⚠️ 易错点
- 数动词不等于数主句谓语;to do、doing、done 可能是非谓语,are 也可能属于内层从句。
- 括起修饰语只是暂时阅读步骤,最终必须还原,否则会丢失条件、否定、范围和限制。
- 逗号不能自动连接两个独立句;阅读中的插入语、从句须按结构识别,作文也不能只靠逗号拼句。
- that 紧挨名词不一定是定语从句;先看它解释名词内容,还是在从句中担任成分并修饰名词。
- 关系词不一定只指最近的单个词,concepts and words 可以共同充当先行词。
- 看到省略要补上下文已知内容;less often 不等于 never,didn't 后要按语境找被省略的动作。
- 译文应保留推测、否定和条件;could make 不要无条件译成‘一定会造成’。
✏️ 自测 5 题
