专题讲解： 定语从句

一. 知识疏理：

1. 定语从句

2. 先行词

3. 关系词的用法：包括关系代词与关系副词

二. 专题讲解：

一. 什么是定语从句？

定语可以由形容词、名词、代词、数词、分词、副词、不定式以及介词短语等来充当，也可以由一个句子来充当。定语从句用来修饰名词、代词或整个主句。

充当定语功能的句子称为定语从句。

e.g: Tom is a hardworking student who always gets first in his class.

汤姆是一个用功的学生，他在班里总是第一名。（修饰名词student。）

e.g: Football is played over 80 countries, which makes it popular.

80多个国家都在踢足球，因此足球很流行。

（修饰整个主句Football is played over 80 countries。）

二. 先行词与关系词

1. 什么是先行词：被定语从句修饰的名词、代词称为先行词。

e.g: Don’t forget the book that I told you to bring.

别忘了我让你带的书。（the book为先行词。）

2. 什么是关系词： 引导定语从句的关联词为关系词，分为关系代词与关系副词。关系代词在定语从句中作主语、宾语、表语、定语等，关系副词在定语从句中作状语。

关系代词有： that, which, who, whom, whose……

关系副词有：where, when, why, ……

e.g: I will never forget the days when I stayed in New York.

注意：

　　①关系词一般紧跟在先行词之后引导定语从句。定语从句总在被修饰的先行词后面。

　　②在定语从句中，关系代词起着代词和连词的作用，关系副词起着副词和连词的作用。

　　③在定语从句中，关系词代替先行词，因此在定语从句中不能再重复作用相当于先行词的词。

下面的句子是错误的：

　　This is the right book that you are looking for the book.（应去掉the book。）

This is the right book that you are looking for it.（应去掉it。）

①常见的关系代词

②常见的关系副词

e.g: Our chemistry teacher is a man who/that can make his class lovely and interesting.

我们的化学老师可以使他的课堂生动有趣。

（who/ that在定语从句中作主语，代指人a man。）

e.g: The books that/ which they bought were written by me.

他们买的那些书是我写的。

（that/which 在定语从句中作宾语，代指物 the books。）

e.g: Make marks in places where you have questions.

在你有问题的地方做出标记.（where为关系副词，在定语从句中作地点状语。）

e.g: I still remember the time when we first met scores of years ago.

我依然记得几十年前我们第一次见面的情景。

（when为关系副词，在定语从句中作时间状语。）

重点：关系代词选择三步骤：

　　步骤一：首先找出先行词。

　　e.g: The book that/which you just laid on the top shelf is mine.

你刚才放在高层书架上的书是我的。（the book是先行词，指物。）

　　步骤二：确定先行词在从句中所作的成分。

　　先行词the book在后面的定语从句中作laid的宾语，因此选择指物的关系代词which/that作宾语。

步骤三：确定关系代词的人称和数。

　　在此处由先行词the book可知是第三人称单数，如果关系代词作主语，则从句的谓语动词相应用单数。

三。关系代词的用法：

常用关系代词有who, whom, whose, that, which, 等。这些关系代词在定语从句中作主语、宾语、表语、定语等。关系代词主要起三种作用：代替先行词、在定语从句中作成分、连接先行词与定语从句。

e.g: This is an old computer. It works much slower.

这是一台旧电脑。它工作起来速度较慢。

（普通代词it代替an old computer。）

This is an old computer which/that works much slower.

这是一台工作起来速度较慢的旧电脑。

（关系代词which/ that代替an old computer。）

（1）who/whom的用法

　　二者都用于指人。who在定语从句中作主语、宾语，whom在定语从句只作宾语。

e.g: In this earthquake, the number of people who lost homes reached as many as 250 000.

在这次地震中死亡的人数多达250 000。（who在定语从句中作主语。）

e.g: The man whom you met just now is my friend.

你刚才见到的那个人是我的朋友。（whom在定语从句作宾语。）

（2）whose的用法：whose一般指人，但有时也指物。在定语从句中作定语。

e.g: You’re the only one whose advice he might listen to.

只有你的建议他可能会听。（whose在定语从句中作advice的定语。）

I’d like a room whose window looks out over the sea.

我想要一个通过窗户可以俯看大海的房间。

（whose在从句中作window的定语。）

（3）which的用法：which一般指物，在定语从句中作主语、宾语。

e. g: Football is a game which is liked by most boys.

足球是大多数男孩子喜欢的一项运动。（which在定语从句中作主语）

e. g: This is the pen which he bought yesterday. 这是他昨天买的那支钢笔。

（which在定语从句中作宾语，可以省略）

（4）that的用法: that指人或物，在从句中可作主语或宾语，还可作表语。作宾语或表语时可省略。指人时相当于who或whom,指物时相当于which.

e. g: The number of the people that/who come to visit the city each year is rising.

每年来参观这个城市的人的数量在增多。（that在定语从句中当主语）

e. g: Where is the man that/whom I saw this morning?

我今天上午见到的那个人在哪儿？（that在定语从句作宾语）

四．关系副词的用法:

常用的关系副词有where, when, why, that等。这些关系副词在定语从句中作状语。

（1）where的用法：在定语从句中作地点状语，指代地点。此时常可用in which, on which, at which, to which等结构代替。

e.g: Potato can be grown in places where it is too cold to grow rice.

（＝Potato can be grown in places in which it is too cold to grow rice.）有些太冷不能种稻米的地方，可以种马铃薯。

（2）when的用法：在定语从句中作时间状语，往往代指时间。此时常可用on which, in which, at which, during which等代替。

e.g: I shall never forget the days when we worked on the farm.

（＝I shall never forget the days on which we worked on the farm.）

我永远也不会忘记我们在农场劳动的那些日子。

（3）why的用法：why在定语从句中作原因状语。可以用for which代替。why不可引导非限制性定语从句，此时可用for which代替。

e.g: I have come around to explain the reason why I was absent from the meeting.

我来是为了向你解释我当时没到会的原因。（why在从句作原因状语。）

（4）that的用法

　　在表明方式、时间或地点的先行词后面，常用that来代替in which，when或where，that也可省去。that在句中不作任何成分，只起到引导定语从句的作用，修饰的先行词常为the way, the time, the day, the place等，此时也可换为其他相应的关系副词。

　　① 表示方式时。that（=in which）常省略。此时不能用how引导定语从句，但把the way去掉之后。可直接用how引导方式状语。

e.g: Can you work out a way （that/ in which） we can solve this problem？

你能找出一种我们可以解决这个问题的方法吗？（that在定语从句中不作成分。）

　　② 表示地点时，that（＝where＝介词＋which）也可省略。

e.g: I have never been to the places（that/ where/ in which） the Indians live.

我从未到过那些印第安人居住的地方。（that在定语从句中不作成分。）

　　③ 表示时间时，that（=when=介词＋which）也可省略。

e.g: I still remember the days （that/ when/on which） I helped my father on the farm.

我仍然记得在农场上给我爸爸帮忙的日子。（that在定语从句不作成分。）

　　④ 另外，关系副词that有时还可用来代替关系副词why，表示原因。

e.g:The reason that（=why）he lost his life was lack of medical care.

他的死是由于缺乏医疗护理。

注意：在下面这个句子中，不能用why，只能用which或that。

I don’t want to hear any reason （that/ which） you might give.

我不想听你给出的任何理由。

（在这个定语从句中，that/ which作定语从句中谓语动词give的宾语。）

五。定语从句中需要注意的问题

1. what，how不可引导定语从句

　　① what本身是复合关系代词，等同于“先行词＋关系代词（which/that）”。因此不能用what引导定语从句。

e.g: Time is what we demand most.

（=Time is all (that) we demand most.）我们所需要的就是时间。

Tell me what is happening.

（=Tell me something that is happening.）告诉我正在发生什么事。

She isn’t what she used to be.

（=She isn’t the one (that) she used to be.）她不是过去的她了。

② how为复合关系副词。本身等同于the way in which，因此，不能用how引导定语从句。

e.g:I don’t like how you behave.

（=I don’t like the way (that/ in which) you behave.）

我不喜欢你行事的方法。

This is how I worked out this problem.

（=This is the way (that/ in which) I worked out this problem.）

这就是我解出这道题的方法。

2．关系代词that和which的用法辨析

　　that和which在定语从句中都可作主语或宾语，指物。作宾语时，均可省略。通常情况下，二者可互换使用。但有时却不宜随便互换。

① 宜用that的情况

1）当先行词是all, much, little, few, something, anything, everything. none, nothing, some等不定代词或被不定代词修饰时。

e.g: Have you taken down everything that Mr Li has said ?（李老师所说的话你都记下来了吗？）

e.g: There is little that I can do for you. （我几乎不能为你做任何事。）

2） 先行词被序数词修饰时，只能用that

e.g: The first place that they visited in London was the Big Ben. （他们在伦敦参观的第一站就是大笨钟。）

3） 先行词被形容词最高级修饰时，只能用that

e.g: This is the best film that I have seen. （这是我看过的最好的电影。）

4）当先行词有the only, the same, the very, 等词修饰时。

e.g: These articles are the very ones that should be read.(这些文章才是应该读的。)

Chatting was the only thing that interested her most. (聊天是她唯一感兴趣的事。)

5) 当主句是以who或which开头的特殊疑问句时。

e.g: Who is the person that is standing at the gate？(站在门口的那个人是谁？)

6）当先行词有两个或两个以上，并且分别表示人和物时。

e.g: She took photographs of the things and people that she was interested in.(她把她所感兴趣的人和物全拍摄了下来。)

7) 当主句以here, there开头时。

e.g: Here is a hotel that you’ve been looking for.(这就是你一直在找的旅馆。)

There is a seat in the corner that is still not taken.(在角上还有一个空位。)
