1、初中定语从句讲解及练习定义：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1.who

6、 (that/which) you asked for.(4) tomorrow i will bring here a magazine for which you asked.(5) well go to hear the famous singer (whom/that/who) we have often talked about.(6) well go to hear the famous singer about whom we have often talked.注意：1.含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等
