1. 在复合句中修饰名词或代词的从句叫做定语从句。被修饰的名词或代词叫先行词。

2. 引导定语从句的关系代词有：which, that, who, whom, whose和as。其作用是：①引导定语从句②代替先行词③在定语从句中充当一定成分。

3. 引导定语从句的关系副词有：where, when, why。可替换成：介词+关系代词。

二、关系词的用法：

一）关系代词的用法

1、作主语用who, which和that, 如：

He is the man who/that lives next door.

The train which/that has just left is for Shenzhen.

2、作宾语用whom, who, which, that, 如：

The man (whom/who/that) we have just seen is a famous writer.

Where is the book (which/that) I bought last week?

注：在非正式文体中，关系代词作宾语时，用于指人的who whom, that和用于指物的which和that通常可以省略；但在介词提前时,或在非限定性定语从句中，关系代词即使作宾语也不可省略。

3、作定语用whose, 如：

(a) He is the man whose car was stolen last week.

(b) It was a meeting whose importance I did not realize at that time.

注："whose +名词中心词"这一结构在定语从句中既能作主语（如上a句），又能作宾语（如上b句）。whose 的先行词常用来指人，但有时也可以用来指具体事物或抽象概念，这时可以与of which 结构互换，词序是："名词+of which"，如：

They came to a house whose back wall had broken down. (= the back wall of which)

He's written a book the name of which I've completely forgotten.
