1.什么是定语？

短前长后
什么可以作定语
2、什么是定语从句？
在复合句中，修饰某一名词或代词的从句叫做定语从句(句意: ……的）作用相当于形容词
朕 喜欢 长得像纯元的 女孩
I like the girls who/that look like Chunyuan.
先行词
关系词
I like the girls (who/that look like ChunYuan.)
1. 被定语从句所修饰的名词或代词叫做“先行词”。
2. 引导定语从句的词叫“ 关系词 ”。
3. 在复合句中，修饰某一名词或代词的从句叫做定语从句
3、定语从句的结构
定语从句
Find out the antecedent(先行词), relative words(关系词）and bracket(括出) the attributive clause（定语从句）
1. She is a girl who/that is always helping others.
2.The man(whom/that)you saw just now is our manager.
3. Don't cut down the tree which/ that gives you shade(阴凉).
4.This is the book (which/that) I bought yesterday.
关系词又分为两派：
左边这路是关系代词，主要有这六个家伙
右边这路是关系副词，有这三个家伙
定语从句
关系词的三个作用:
1. 连接作用：连接主句和定语从句。
2. 替代作用(替代先行词)
3. 成分作用：在定语从句中担当成分
先行词
关系词
