修饰名词和代词的成分，作定语的除了形容词外，还有代词、数词、名词、介词短语。
定语:
my teacher
three boys
clothes shop
the students in class
定语的位置
1. This is a flower basket.
2. This is a basket full of flowers.
单个的词作定语时要放于被修饰词的前面，前置定语
短语作定语时要放于被修饰词的后面，后置定语
看下列句子，是什么作定语呢？
She is the teacher that I never forget.
This is a basket that I want to put flowers in.
用句子充当定语
基本定义：
在复合句中，修饰名词或代词的从句叫定语从句。
定语从句相当于一个形容词，跟在名词或代词后修饰该名词或代词。
She is the teacher that I never forget.
She is the person that I like.
1.主句
2.从句
3.先行词
4.关系词
构成定语从句的要素：
把主句和从句连接起来
1.主句：整个句子的主干部分。
2. （定语）从句：对主句起修饰作用的句子。
She is the teacher that I never forget.
3. 被定语从句修饰的名词或代词叫先行词。
4. 引导定语从句的词叫关系词。
关系代词：who, whom, whose, that, which
关系副词：when, where, why
高考考点所在
She is the teacher that I never forget.
定语从句的来源：
I have a friend,
he likes listening to classical music.
I have a friend.
He likes listening to classical music.
复合句中一定要有2套主谓（宾），一套属于主句；一套属于从句。
I have a friend who likes listening to classical music.
