同学们，定语从句是英语中一个承前启后的语法点，学好定从，能使你对英文的“结构”理解更加深刻，同时对英语长句和难句的分析和理解有很大的帮助。

主从复合句

主从复合句是由一个主句和一个或一个以上的从句构成的。主句是句子的主体，从句可视为句子的一个成分。(大鱼吃小鱼)从句在主从复合句中可以起主语，宾语，表语，定语，状语作用。从句在全句中起什么作用，就叫做什么从句。例如从句起状语作用就叫状语从句。从句都需要有连词来和主句连接。

①  When I came in, I found Tom seated here（状从）

②   I don’t know when we’ll start off tomorrow. （宾从）

③   The question is when we’ll start off tomorrow. （表从）

④  I’ll never forget the days when we worked together. （定从）

 

①   Where there is a river, there is always a city. （状从）

②   I want to know where Tom lives. （宾从）

③   It is where I was born. （表从）

④  This is the factory where I worked.（定从）

 

① Please tell me whose book it is.

② This is Tom, whose father is a doctor.

 

① I think that you are right. （宾从）

② The fact is that you are right. 表从

③ The news that we won the game is exciting. （同位语从句）

④ The news that we won the game is exciting. （定从）

          1. 定语从句

主从复合  2. 名词性从句

句(大鱼      ① 主语从句   ② 宾语从句

吃小鱼)      ③ 表语从句   ④ 同位语从句

          3. 状语从句

 

※ 连词引导小鱼

 

定语从句

在主从复合句中修饰名词的从句叫做定语从句。被定语从句修饰的名词叫做先行词。定语从句放在先行词的后面。

This is a factory.

I worked in the factory once.

※This is the factory in which/where I worked once.

 

This is a factory.

The factory makes100 cars every day.

※This is the factory which/that_ makes 100 cars every day

以上两句中划横线的句子就是两个定语从句，它们的先行词都是“factory”.

但两个从句的连词不一样，分别是”where”和”which”或”that”。这是由于先行词还原于定语从句时，在从句中充当的句子成分不同所致。

定语从句的连词主要有两个作用：

1.   和其它种类的从句(还有状语从句和名词性从句)连词一样，起连接两个句子  （即大鱼和小鱼）的作用。

2. 还在定语从句中要担当句子成分，连词的选择由先行词在定语从句担当的句子成分来决定的。定语从句的连词本身不具有意思，仅起连接和充当句子成分两个作用。

This is the expert who will give us a talk on science and technology.

此定语从句中的who 有两个作用：

① 连接主句“This is the expert”和从句“who will give us a talk on science and technology.”

② who 在从句中还充当从句的主语。

This is the expert and he will give us a talk on science and technology.

==This is the expert who will give us a talk on science and technology.

 

 

定语从句类题目的做法（三步走）

1.先确定先行词。

2.再确定定语从句。

3. 最后由先行词在定语从句中充当的句子成分来确定关系词。

 

先行词	在定从中充当的成分	连词
人	做主语	who
人	做宾语	whom
物	做主语和宾语	which
人；物	做主语和宾语	that
人；物	做定语	whose
地点	做地点状语	where
时间	做时间状语	when
reason	做原因状语	why
