定义

1．在主从复合句中，对某一名词或代词起修饰作用的从句叫定语从句。被修饰的名词或代词叫先行词，引导定语从句的词叫关系词。

2．关系词分为关系代词(that, which, who, whom, whose, as等)和关系副词(when, where, why等)两类。

关系代词的基本用法

1．who指人，在定语从句中可以充当主语、宾语或表语。

◆The children who were injured in a car accident are being treated in the hospital now．　在车祸中受伤的孩子们现在正在医院接受治疗。(作主语)

◆Danny was a man who we rescued from the ruins．

丹尼是我们从废墟中救出来的一个人。(作宾语)

2．whom指人，在定语从句中作宾语，可省略，也可用who代替。

◆Rose is the person (who/whom) you should care about．

罗丝是你应该关心的人。

◆The boy (who/whom) the teacher often praises is their monitor．

老师经常表扬的那个男孩是他们的班长。

3．whose既可以指人，也可以指物，表示“所属”关系，whose在定语从句中作定语。
