译林版必修第一册Unit3单元语法--关系代词引导的限制性定语从句语法精析在复合句中，修饰某一名词、代词或整个主句的从句叫定语从句。

被定语从句修饰的名词或代词叫先行词，连接先行词和定语从句的词叫关系词。

关系词的主要作用是连接主句和从句，同时指代先行词，并在从句中充当一定的句子成分。

关系词分为关系代词和关系副词两种，关系代词有that，which，who，whom，whose等；关系副词有when，where，why。

一、关系代词的用法1．who指人，在定语从句中作主语或宾语。

The person who tricked me was one of my classmates.骗我的那个人是我的一个同学。

He is the man who I respect very much.他就是我非常尊重的那个人。

2．whom指人，在定语从句中作宾语，常可省略。

The old man (whom) the girl had tricked was my grandfather.女孩欺骗的那位老人是我的爷爷。

[温馨提示](1)关系代词whom在口语或非正式文体中常可用who/that来代替。

The boy (who/whom/that) we saw yesterday was John’s brother.昨天我们看到的那个男孩是约翰的哥哥。

(2)在从句中作介词的宾语且直接跟在介词后时，用whom，不用who。

He is a man from whom we are all ready to learn.他是我们大家都准备向他学习的人。

3．which指物，在定语从句中作主语或宾语，作宾语时可省略。

The gold medal (which) she won has been given to her old school.她曾经获得的那块金牌已经被送给她的母校了。

4．that指人时，相当于who或whom；指物时，相当于which。
