一、定语从句的概念
在复合句中,修饰某一名词或代词从句叫定语从句,在句中起定语的作用.
被定语从句修饰的词叫做先行词。引导定语从句的词叫关系代词或关系副词。如:
The man who lives next to us is a policeman.
先行词 关系代词 定语从句
二、关系代词和关系副词的用法:
关系代词和关系副词又称关系词,用来引导定语从句、代替先行词并在从句中担当一个成分。其用法见下表:

限制性定语从句 非限制性定语从句
从句与先行词的关系 从句是先行词不可缺少的定语,如果省去,主句的意思就会不完整或不明确。 从句只是对先行词的附加说明,如果省去,主句的意思仍然清楚或完整
标 点 从句和主句之间不用逗号分开 从句和主句之间通常用逗号分开
关系
代词 指人who (that) whom 指人who(作主语)whom(做宾语)
指物which (that) 指物which
人和物的whose 人和物的whose
关系代词在从句中作宾语时可以省去 关系代词一般不可省
修饰 从句只修饰一个名词或代词 可以修饰一个词也可修饰整个主句
翻译 定语从句译在被修饰词的前面 定语从句通常被译成另一个独立的句子
