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

  1. 引导定语从句
  2. 代替先行词
  3. 在从句中充当一定成分

经典例句

  1. The boy who is standing there is my brother. (站在那里的那个男孩是我弟弟。)
  2. 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

  1. I know the girl who won the prize.
  2. The person whom I called didn’t answer.
  3. 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

  1. 先行词是不定代词(all, everything, nothing, anything, something等)

    • Is there anything that I can do for you?
  2. 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.
  3. 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.
  4. 先行词既有人又有物

    • He talked about the people and things that he saw.
  5. 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

  1. 非限制性定语从句

    • The book, which I bought yesterday, is interesting.
  2. 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。)

非限制性定语从句

  • 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

  1. 根据先行词的习惯搭配
  2. 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.

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

  1. 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.
  2. 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
