高中英语语法定语从句Handsome boys=the boys who are handsome Beautiful flowers=the flowers which are beautiful定语从句(Attributive Clauses)定义:从句由关系代词或关系副词引导,作定语,修饰主句的某个名词和代词,相当于形容词,一般紧跟在它所修饰的先行词后面。
被定语从句修饰的词叫先行词,引导定语从句的词叫关系词。
关系词可分为:关系代词(who, whom, whose, which, that)关系副词(when, where, why)关系词替代先行词,在从句中充当相应的某个成分。
在定语从句中,当who, which, that作主语时,谓语的单复数应与先行词保持一致。
关系词常有3个作用:①引导定语从句。
②代替先行词。
③在定语从句中担当一个成分。
定语从句分为限制性定语从句和非限制性定语从句。
非限制性定语从句与先行词的关系不如限制性定语从句与先行词的关系紧密,没有它,主句的意思也清楚,因此用逗号隔开。
关系词在非限制性定语从句中的用法与在限制性定语从句中的用法基本一样。

2)that前不能有介词。
