定语从句 定义 I. 定语从句起形容词的作用，在句中修饰一个名词或代词。被修饰的词叫做先行词，引导定语从句的词叫关系词，他的作用一是放在先行词与定语从句中间起了连接作用，二是在从句中担当一个成分，并与先行词保持数的一致。 关系词 先行词 从句成分 例句 备注 关系代词 who 人 主语 Do you know the man who is talking with your mother? whom, which和that在从句中做宾语时，常可以省略，但介词提前时后面关系代词不能省略，也不可以用that whom 人 宾语 Mr. Smith is the person with whom I am working The boy (whom) she loved died in the war.. whose 人，物 定语 I like those books whose topics are about history.

They won the game, which we hadn’t expected. As is well known, he is a famous film star in the 1980s.
