第9周:定语从句
Day 58:定语从句基础概念
什么是定语从句?
定语从句是用来修饰名词或代词的从句,通常紧跟在被修饰的词(先行词)后面。
基本结构
先行词 + 关系词 + 从句
关系词分类
关系代词:who, whom, whose, which, that, as
关系副词:when, where, why
关系词的作用
- 引导定语从句
- 代替先行词
- 在从句中充当一定成分
经典例句
- The boy who is standing there is my brother. (站在那里的那个男孩是我弟弟。)
- This is the book which I bought yesterday. (这是我昨天买的书。)
Day 59:关系代词who, whom, whose
who(主格)
- 指人,在从句中作主语
- The girl who is singing is my sister. (正在唱歌的女孩是我姐姐。)
whom(宾格)
- 指人,在从句中作宾语(口语中常用who代替)
- The man whom you met yesterday is my teacher. = The man who you met yesterday is my teacher.
- 介词后只能用whom
- The man to whom I spoke is my uncle.
whose(所有格)
- 指人或物,表示“……的“
- The boy whose father is a doctor is my friend. (父亲是医生的那个男孩是我的朋友。)
- I saw a house whose windows were broken. (我看到一所窗户破了的房子。)
经典例句
- I know the girl who won the prize.
- The person whom I called didn’t answer.
- This is the student whose homework is the best.
Day 60:关系代词which, that
which
- 指物,在从句中作主语或宾语
- The book which is on the desk is mine.(作主语)
- The book which I bought is interesting.(作宾语,可省略)
that
- 指人或物,在从句中作主语或宾语
- The boy that is playing football is Tom.(指人)
- The pen that you gave me is very nice.(指物)
只能用that的情况
-
先行词是不定代词(all, everything, nothing, anything, something等)
- Is there anything that I can do for you?
-
先行词被序数词或最高级修饰
- This is the best film that I have ever seen.
- He is the first person that arrived.
-
先行词被the only, the very, the same, the last修饰
- This is the only book that he has.
- This is the very thing that I want.
-
先行词既有人又有物
- He talked about the people and things that he saw.
-
主句是who或which引导的疑问句
- Who is the girl that is standing there?
只能用which的情况
-
非限制性定语从句
- The book, which I bought yesterday, is interesting.
-
介词后
- This is the house in which I lived.
Day 61:关系副词when, where, why
when
- 指时间,在从句中作时间状语
- = at/on/in + which
例句:
- I’ll never forget the day when I met you. = I’ll never forget the day on which I met you.
where
- 指地点,在从句中作地点状语
- = at/in/to + which
例句:
- This is the school where I studied. = This is the school at which I studied.
why
- 指原因,在从句中作原因状语
- = for + which
- 先行词通常是reason
例句:
- The reason why he was late is unknown. = The reason for which he was late is unknown.
判断技巧
看关系词在从句中的成分:
- 作主语/宾语 → 用关系代词
- 作状语 → 用关系副词
对比:
- This is the place where I was born.(作状语)
- This is the place that/which I visited.(作宾语)
Day 62:限制性与非限制性定语从句
限制性定语从句
- 对先行词起限定作用,不可省略
- 与先行词之间无逗号
例句:
- The students who work hard will succeed. (努力学习的学生会成功。)

- 对先行词起补充说明作用,可省略
- 与先行词之间有逗号
- 不能用that
例句:
- My mother, who is a teacher, is very kind. (我妈妈是一位老师,她很善良。)
指代整个主句
非限制性定语从句可以指代整个主句,用which或as引导:
-
He passed the exam, which made us happy. (他通过了考试,这使我们很高兴。)
-
As is known to all, the earth is round. = It is known to all that the earth is round.
Day 63:定语从句高级用法
介词 + 关系代词
结构:介词 + which/whom
例句:
- This is the pen with which I wrote the letter.
- The man to whom I spoke is a doctor.
介词的选择
- 根据先行词的习惯搭配
- 根据从句中动词的搭配
例句:
- The chair on which he is sitting is broken. (sit on the chair)
- I don’t know the girl about whom they are talking. (talk about the girl)
“介词+关系代词+名词“结构
- The building, the roof of which is red, is our library. = The building, whose roof is red, is our library.

名词 + that从句
例句:
- The news that he won the prize surprised us. (他获奖的消息使我们惊讶。)
- I have no idea when he will come. (我不知道他什么时候来。)
同位语从句与定语从句的区别
| 区别点 | 同位语从句 | 定语从句 |
|---|---|---|
| 功能 | 解释说明名词的具体内容 | 修饰限定名词,说明哪一个 |
| that的作用 | 仅起连接作用,不作成分 | 作从句中的成分(主语/宾语) |
| that能否省略 | 不能省略 | 作宾语时可省略 |
| 判断方法 | 从句内容=名词内容 | 从句修饰限定名词 |
详细对比例句:
-
同位语从句:
- The news that he won the prize is true.
- 分析:that he won the prize 解释了 news 的具体内容(消息是什么?→ 他获奖了)
- that 在从句中不作任何成分,只起连接作用
- 可以改写为:The news is that he won the prize.
-
定语从句:
- The news that he told me is true.
- 分析:that he told me 修饰 news,说明是“哪个消息“(他告诉我的那个消息)
- that 在从句中作 told 的宾语(told me the news)
- that 可以省略:The news he told me is true.
判断技巧:
- 把 that 从句去掉后,如果名词内容不完整 → 同位语从句
- 把 that 从句去掉后,如果名词意思完整 → 定语从句
- 检查 that 在从句中是否充当成分,不作成分 → 同位语从句
