高一英语上册语法知识点小结

Tony寒假英语培训定语从句专讲

（一）定语从句分为限定性定语从句和非限定性定语从句：

限定性定语从句：从句对先行词进行必要的描述或说明，缺少它，则句义显得不完整，从句与先行词紧密相连。

非限定性定语从句：对先行词进行补充说明，解释，它与先行词之间有逗号隔开。

（二）定语从句的结构：在复合句中，修饰某个名词或代词的句子（做这个名词或代词的定语）叫定语从句，定语从句一般放在被修饰的名词或代词后面，被修饰的名词或代词叫做定语从句的先行词，它与定语从句之间要有一个词连接，这个词指代先行词的内容叫做关系词（关系代词或关系副词：that, which, who, whose, when, where, why）。先行词在定语从句中充当主语，宾语，时间，地点，原因状语。

（三）关系词前面可以根据定语从句的内容加上一些介词，这些关系词在介词后面常用which 或whom.

1. There was a man with whom I would have to work together and finally the manager of the company.知识重点与难点
