第二講 定語從句
一 什么是定語從句
閱讀下列句子，找出哪一句是定語從句
1. My doctor told me to live where the air is fresh .
2. Tom was sleeping when the door bell rang .
3. Do you remember the teacher who taught us English at middle school ?
4. Can you tell me when the Flight 5571 will depart ?
在復合句中充當定語的從句叫定語從句。定語從句的作用相當于形容詞，用來修飾主句中的某一個名詞或代詞或整個句子。被定語從句修飾的詞叫先行詞，定語從句一般緊跟在它所修飾的先行詞之后。因此，通常定語從句被視為一個句子與一個名詞的關系。在先行詞和定語從句之間起連接作用的叫關系詞。關系詞有關系代詞和關系副詞兩種。
例如：
He is the boy who often goes to school late.
注意
關系詞在定語從句中的三大作用：
1. 連接作用---連接先行詞和定語從句。例如：
I gave her all the money that I had .我把我所有的錢都給了他。（that 連接先行詞money 和定語從句I had ）.
2. 替代作用---在定語從句中替代從句所修飾的先行詞。例如：
The man who lives next door is a famous teacher.
2. 成分作用---在定語從句中作主語、賓語、定語或狀語。 例如：
I like pictures which are painted in the traditional Chinese style. 我喜歡傳統的中國畫（which 在定語從句中作 主語）。
二 關系代詞和關系副詞的用法

2. Mary is the girl who works in Japan .

關系代詞和關系副詞的用法
定語從句類型 特點 句子序號
由關系代詞which /that /who/whom 引導 關系代詞在從句中作主語
關系代詞在從句中作賓語
關系代詞which 指代前句所屬之事
由關系副詞when /where/why 引導 定語從句中不缺主語或賓語；when /where /why 充當從句的時間、地點、原因狀語。
Where 所指代的是一個抽象的地點，例如某一種情況、某一個領域。

三 關系詞使用的注意事項
引導定語從句的關系詞的選用比較復雜。除了牽涉到所指的先行詞是人還是物，所引導的定語從句是限制性的還是非限制性的，以及關系詞在從句中充當什么句子成分外，還要根據習慣用法而定。
（一） 只能使用that ,who , whose 的定語從句。
