一、 定义：
在复合句中，修饰某一名词或代词的从句叫做定语从句。
如：1) The man who lives next to us is a policeman.
2) You must do everything that I do.
上面两句中的man和everything是定语从句所修饰的.词，叫先行词，定语从句放在先行词的后面。
引导定语从句的词有关系代词that, which, who(宾格who, 所有格whose)和关系副词where, when、why
关系词常有三个作用：
1、引导定语从句
2、代替先行词
3、在定语从句中担当一个成分
二、关系代词引导的定语从句
指人，在从句中做主语
The boys who are playing football are from Class One.

2. whom指人，在定语从句中充当宾语，常可省略。

3. which指物，在定语从句中做主语或者宾语，做宾语时可省略

( which 在句子中做主语)

4. that指人时，相当于who或者whom;指物时，相当于which。

5. whose通常指人，也可指物，在定语从句中做定语

whose指物时，常用以下结构来代替
