定语从句

先行词的概念

被定语从句修饰的词叫做先行词

在定语从句的含义层面上，连词等同于先行词，即使用先行词确定连词的含义。

定语从句的分类

限定性定语从句与非限定性定语从句

限定性定语从句与非限定性定语从句的异同

限定性定语从句
    1主从之间无逗号
    2.从句只能修饰先行词
    3.连词正常使用(八个连词)
非限定性定语从句
    1.主从直接有逗号隔开
    2.从句既能修饰先行词，也能修饰句子
    3.连词无that，其他连词用法相同。

定语从句中的连词分为两类

有成分，有含义(4个)

• that 做主/宾，指人/物

This is the program that/which is interesting.

• which 做主/宾，指物

This is the program that/which is interesting.

• who 做主，指人

Du is person that/who likes shoes.

• whom 做宾，指人

Du is person that/whom I admire.

有成分，有含义的连词的注意事项

只能用that的情况

• （1）先行词为指物的不定代词:all-，every-，any-，some-，no-

You can choose anything that you like.

All the things that your ordered are here.

• （2） 先行词被绝对含义的词修饰
  • 序数词 The first thing that attracted me was your smile.
  • 最高级 This was the happiest moment that happened in my life.
  • the only 唯一
  • the last 恰好
  • the very 最后 Better days is the only film that l like.
• (3)先行词既有人又有物

The kids and their behaviors that I saw shocked me.

不能用that的情况

• (1)在非限定性定语从句中，有逗号，无that
• (2)介词+连词做宾语的情况下，指物用which,指人用whom

The board on which they stood was frightening.

The girl with whom you talked just now is my friend.

无成分，有含义(4个)

• why 为什么

I can’t forget the reason why I chose CS.

• when 何时

I still remember the first day when I came to CS

• where 何地

CS is the city where I have stayed for four years

• whose 谁的

无成分，有含义的连词的注意事项

介词+which的两种情况

方法： 将先行词带到从句中，从句与先行词用哪个介词连接，就填哪个介词。

• （1）介词+which替代when where why

原句： I still remember the first day when I came to CS.

改写后：I still remember the first day on which I came to CS.

• （2）介词+which固定用法(根据含义)

This is the book on which I spent 100 RMB.

非限制性定语从句中的固定句式

名/代/数 of+which/whom…. 先行词是物用which 先行词是人用whom

In this movie there are many character,2 of whom are animals. The main character is a cat, the name of which is Garfield. A lot of people, most of whom are children like the movie.

补充

• 定语从句中，连词作宾语可以省略(that which whom)
• 学会区分定语从句与同位语从句

The reason why he didn’t come was that he was injured. 定语从句

I hope that the suggestion that I have offered dose good to them all.
