定语从句——关系代词引导的定语从句 【关系代词引导的定语从句】 （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。 定语从句是指在一个句子中作定语的句子，定语从句要放在所修饰的词后。 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。 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指人，在从句中做主语 (1)The boys who are playing football are from Class One. (2)Yesterday I helped an old man who lost his way. 2. whom指人，在定语从句中充当宾语，常可省略。 (1) Mr. Liu is the person (whom) you talked about. 注意：关系代词whom在口语和非正式语体中常用who代替，可省略。 (2) The man who/whom you met just now is my friend. 3. which指物，在定语从句中做主语或者宾语，做宾语时可省略 (1) Football is a game which is liked by most boys.
