定语从句

一.概念

1.定语从句: 在复合句中用来修饰名词或代词,这个句子就叫做定语从句. 2. 先行词: 被修饰的名词或代词称为先行词

3.关系词: 关系代词:who, whom, that, which, whose as,在从句中做主语，宾语，定语，表语e；关系副词:when, why, where,在从句中做状语。

4.关系词的作用：(1) 连接先行词和定语从句,构成主从句

(2) 从句中代替先行词(但先行词不可省), 关系词在从句中做宾语时候可以省略

(3) 在从句中做句子成分

均可以指代主句的一部分或整个句子的内容，在从句中做主语，宾语，表语，一般可互换。

Eg. The elephant is like a snake, as/which anybody can see. He didn`t say a word, which(不用as) surprised us.(关系代词代替整个主句且在从句中做主语且谓语是非连系动词时只能用which) 注意：下列情况只能用as: ①

在句首时②表示“正如，正像”之意时，只能用as ,而which无此意③as可用于类似插入语的句式中，而which则不能如“as is said above, as is known to all, as it is 等。

6、关系代词做主语时，谓语中单复数的判断：与先行词的单复数保持一致。

He is one of the students who _____English well. He is the only one of the students who ______

English well. One of the boys who ___ my friends ____ good at speaking English. 7、几种比较复杂的定语从句

1.Way后面的定语从句

The way that/in which/--- 2.Time后定语从句

time表示“次数”时用that 引导，也可以省略that time表示“一段时间”时用

when ,或at/during which ，不可省略。

3. The same…as…/that…,such…as/that

This is the same bag as I lost yesterday.(同类不同物）

This is the same bag that I lost yesterday.（同物）

He is such a funny sort of person as I don`t understand at all.（as引导定语从句，且在做宾语）

It`s such a heavy stone that none of us could lift it.（that引导结果状语从句，不做成分）
