牛津深圳版英语九年级上册 Unit 7 Grammar :定语从句 一、定语从句及相关术语 定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。 先行词：被定语从句修饰的那个名词或代词称为先行词。 关系词：引导定语从句的关联词称为关系词。关系词有关系代词和关系副词。 关系代词：who, whom, whose, which, that, 关系副词：where, when, why等。 关系词常有三个作用：引导定语从句；代替先行词；在定语从句中充当一定的句子成分。 Harry Potter is the most interesting novel that I have read. (that I have read是定语从句；novel是先行词；that 是关系代词，代替先行词novel，在从句中作宾语。) 注: 关系代词在句中充当主语、宾语，因此定语从句中不能再出现关系代词所替代的名词或代词。 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。(如介词提前则不能省) (1) Mr. Liu is the person (whom) you talked about on the bus. (2) Mr. Ling is just the boy whom I want to see. (3) The man to whom I talked is Mr. Li. 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。 (4) 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. (2) This is the pen (which) he bought yesterday.
