定语从句
考点揭密
1. 定义： 在复合句中修饰名词、代词，并由关系代词或关系副词引导的从句称为定语从句。
（1）The girl {that /who our teacher is talking to }is lucy.（指人，作宾语）
（2）Do you know him {that /who Jim is talking about｝
（指人，作宾语）
2.先行词：定语从句所修饰的名词或代词称为先行词。
3.关系词：引导定语从句的词叫关系词。关系词在句中充当一定的句子成分。
（1）The girl that is reading English is Lucy.(主语)
（2） Do you know the boy that studies Chinese very well (主语)
4.初中教材着重介绍了关系代词that,which,who，whom,whose所引导的定语从句，以及关系副词where，when，why所引导的定语从句。
