初三英语定语从句知识精讲（一）
定语从句（一）
一. 概念介绍：
1. 在复合句中，修饰名词或代词的从句叫定语从句。

2. 被定语从句所修饰的名词或代词叫做先行词。

3. 定语从句一般都要放在先行词的后面。

4. 引导定语从句的有关系代词who，whom，whose，which和that及关系副词when，where 和why等。

5. 引导定语从句的关系代词和关系副词除了在先行词和定语从句之间起联系作用之外，它们还可以做定语从句的一个句子成分。

例句：
The boy [ who is playing football ] is my brother .
先行词关系代词定语从句
Do you remember the place [ where we have watched the dolphin show ? ] →定语从句
先行词关系副词
二. 关系代词引导的定语从句：（关系代词可以作定语从句中的主语，宾语和定语）

6. 注意：关系代词that ，which ，who 在定语从句中作主语时，不能省略。

作宾语时，在口语中或非正式文体中经常省略。

Whom 作宾语时，也常省略。

但若作介词宾语时，且介词置于关系代词前面时：A. 指人时，只能用whom （不能省略），不能用who 或that 。

B. 指物时，只能用which （不能省略），不能用that 。

eg .
⎩
⎨⎧.teacher maths my is now just to spoke I that /whom /who person The .teacher maths my is now just spoke I whom to person The ⎩⎨⎧.
year last in lived we that /which room the is This .year last lived we which in room the is This 含有介词的短语动词一般不拆开，介词仍然放在动词后面。

eg .
Is this the book （which / that ）he was looking for ?
The babies （whom / that ）the nurses are looking after are very healthy .
7. 定语从句中常用that ，而不用which 的情况。

（1）被修饰的先行词为不定代词时。

eg .
We should do all that our teacher asks us to .
There is nothing that I want to talk about .
I like the one that you bought yesterday .
（2）先行词被only ，any ，few ，little ，no ，all ，one of ，just ，very 等修饰时。

eg .
You can take any book that you like .
She is one of the few persons who know Japanese .
The only thing that we can do is to study hard .
（3）先行词是序数词或被序数词修饰时。

eg .

This is the third story that our grandma has told us .
（4）先行词是最高级或被最高级修饰时。

eg .

（5）先行词既有人又有物时。

eg .

（6）若有两个从句，其中一个关系代词已经用了which ，另一个则用that 。

eg .
Edison built up a factory which produced things that had never been seen before .
（7）主句是There be 结构，修饰其主语的定语从句用that 作关系代词。

eg .
There is a man that is reading under the tree .
（8）被修饰成分为表语，或者关系代词本身是定语从句的表语时。

eg .
That’s a good book that will help you a lot .
My home village is no longer the place that it used to be .
8. 定语从句中常用who，而不用that的情况。

（1）先行词为one，ones，anyone或those时。

eg .
The person I want to learn from is one who studies hard and works well .
Anyone who failed the exam should do more exercises .
（2）在There be结构中，修饰主语的定语从句常用关系代词who指代人。

（3）当先行词有较长的后置定语时。

eg .
I was talking to a person at three yesterday who comes from Canada .
[例1] We don’t like the people smoke a lot .
答案：who / that
分析：先行词是people，表示“人”，所以关系代词用who或that，而且这两个关系代词在从句中做主语，因此不可以被省略。

[例2] A blind person is one cannot see anything .
答案：who
分析：先行词是one，指人，关系代词可选用who或that，但由于先行词是one，按照规定，关系代词只能用who。

[例3] This is one of the songs that very popular among young people .
A. is
B. are
C. was
D. were
答案：B
分析：“one of the + 复数名词”这个结构后面的定语从句中的谓语动词常用复数，但若这一结构前面带有the only这个限定语时，后面的定语从句中的谓语动词则用单数形式。

eg .
He is the only one of the farmers who has learned the Rnowledge of farming .
