定语从句定语从句的构成：两个简单句：A man is sta nding there.The man is my brother.= 主从复合句：The man who is standing there is my brother.先行词：行，走路的意思。

先行词就是放在从句前面的词，但是本身为定语从句中的一部分。

所以先行词在从句中作什么成分从句中就用什么样的引导词。

关系词：代替先行词承担从句中的句子成分，放在句首引导从句，所以也叫引导词。

(1.关系代词：在从句里代替先行词充当_______________ 、_________ 、__关系词的种类::I 2.关系副词：在从句里代替先行词充当 _________________关系词的作用：①代替前面的先行词在从句中充当一定的成分② 把两个句子连起来一、关系代词：注意：⑴、当先行词在从句中作宾语的时候可以省略引导词把下列两个简单句合成一个主从复合句1.

22定语从句定义an exciting match:形容词可以放在名词之前作定语，来修饰名词 the book in my hand:介词短语可以放在名词后作定语，修饰名词。

但如果修饰名词的定语不是某一个词或短语，而是一个句子时，我们就把这个句子叫做定语从句。

定语从句相当于形容词或者介词短语的作用, 通常跟在所要修饰的中心名词（先行词）之后，由关系代词或关系副词引导。

注意关系代词who, whom, which, that, as, whose 等跟在先行词的后面，指代先行词，引出定语从句。

在从句中充当主语、宾语、表语、定语的作用。

1 who 的用法先行词必须是人，作主语和宾语The man who spoke at the meeting this morning is a famous lawyer. The girl who you saw just now is Jane.作宾语时，可用whom, that 替换, 可以省略。
