定语从句中的基本概念
1.定语从句是在句子中承担定语功能,
修饰主句中某一名词或者代词的句子
Do you know the girl who is wearing a large hat
2.被修饰的名词或者代词称为先行词
引导定语从句的词称为关系词
关系词有关系代词和关系副词两类
The boy who was in the office just now is my brother.
I will never forget the days when we lived in Tangshan.
定语从句的定义和分类
4.定语从句有限定性定语从句和非限定性定语从句两种
I was the only person in our office who was invited.
Tom’s father, who is over sixty, still works hard day and night.
5.限定性定语从句与主句关系密切,
如去掉从句,主句意义不完整,甚至不合逻辑
6.非限制性定语从句 对主句起到补充说明的作用
如去掉定从句,意思仍然完整
形式上用逗号隔开,不能that用引导。
