定语从句

【概念讲解】

名词或代词由一个从句来修饰，该从句即定语从句。定语从句一般后置，但as引导的修饰全句的定语从句可以前置。

引导定语从句的词有关系代词that which who whom whose as等以及关系副词when where why等。关系代词或关系副词放在被修饰的名词或代词（又叫做先行词）和定语从句之间起联系作用，同时又作定语从句中的一个成份。

【要点难点】

1)that和which的用法区别

只用that的情况：

①先行词由最高级修饰时，如the best work that I can do。

②先行词由序数词修饰时，如the second book that I bought。

③先行词由the last the only the same the very等修饰时。

④先行词是不定代词all anything everything little much nobody nothing等时，如anything that he does; all that I can do now等。

⑤先行词有any no all等限定词时，如all the words that I’ve learned。

⑥先行词为词组，该词组既含人又含物时，如the city and the people that I visited。

只用which的情况：

①在非限定性定语从句中（定语从句前有逗号）。

②介词后。

请看that和which的使用例句：

It’s the best film that’s ever been made on the subject of madness. 这是以精神病为题材而拍摄的影片中最好的一段。

Shakespeare is the greatest poet that England has ever had. 莎士比亚是英国最伟大的诗人。（本句中先行词虽是人，但由于前面也有形容词最高级修饰，仍用that较好）

Take the first opportunity that offers. 抓住第一个出现的机会。

He is the last person that one would suspect. 人们最不可能怀疑他。

Man is the only creature that is gifted with speech. 只有人类具有语言的天赋。

A fool sees not the same tree that a wise man sees. 一个傻瓜看到的树和一个聪明人看到的树不一样。

Those were the very words that he said at the meeting. 这些就是他在会上说的原话。

All that glitters is not gold. 闪光的并不都是金子。

Anything that you have to say had better be said in each other’s presence. 有话最好当面说。

I still can’t forget the places and the people that I visited during last summer vacation. 我仍然难以忘怀去年暑假我见到的地方和人。

2)关系代词（that which who whom等）和关系副词（when where等）的用法区别

①关系代词在定语从句作主语、宾语或表语，而关系副词在定语从句中作状语。

②分析时主要从动词的及物性或有无介词来考虑。

看如下对比例句：

①This is the factory where my father once worked. 这是我父亲曾工作过的工厂。（worked是不及物动词，不接宾语，所以不用which/that。where相当于in the factory）

This is the factory which/that my father once worked in.（worked in的宾语是factory，故用关系代词which/that）

②I will never forget the days which/that I spent in the wood near our village. 我忘不了我在我村边小树林里度过的日子。（the days是spent的宾语）

I will never forget the days when I spent my holidays with my grandparents. 我忘不了我和我的祖父母一起度假的日子。（spent的宾语是holidays，不是the days）

I will never forget the small village where I spent my holidays. 我忘不了我度假的小村庄。（与上句一样，spent的宾语是my holidays）

③Is this the school which/that you visited the other day? 这是你几天前参观过的学校吗？（the school作visited的宾语）

Is this the school where you visited your teacher the other day? 这是你几天前拜访你老师的学校吗？（visited在定语从句中有自己的宾语your teacher，所以不用that/which）

3)those who和he who句型

两个常用句型。He who常用于谚语中。请看例句：

He who doesn’t reach the Great Wall is not a true man. 不到长城非好汉。

God helps those who help themselves. 上帝帮助自强的人。

He who insists on seeing with perfect clearness before he decides never decides. 坚持一切看清楚之后才做决定的人永远也做不了决定。

He was a bold man who first ate an oyster. 第一个吃牡蛎的人是勇敢的人。

4)whose的用法

whose是关系限定词，既可以指人也可以指物，即既可以说“某人的”，也可以说“某物的”。

Fortune never helps the man whose courage fails. 运气永远不会帮助丧失勇气的人。

That's the man whose house has burned down. 那就是那位房屋烧毁的人。

Have you noticed the house whose windows are closed now? 你注意到了那家窗户关着的房子吗？

He’s written a book whose name I have completely forgotten. 他写了一本书，书名我完全忘记了。

Above the trees are the mountains whose magnificence the river faithfully reflects on the surface. 在树林的高处是山，其壮丽的景色完全映照在河面上。

注：在正式文体中，指物时，whose往往用of which表示。of which可放在被修饰的名词之前或之后，而whose只能放在被修饰的名词之前。例如：The house whose windows/of which the windows/the windows of which are broken is unoccupied.（那间窗户破了的房屋没人居住。）

whose前有时有介词。

The teacher in whose class my daughter is studying is a kindhearted man. 我女儿所在的那位老师心地善良。

5)限制性定语从句和非限制性定语从句的区别

限制性定语从句和非限制性定语从句的区别：限制性定语从句是先行词（即被修饰词）不可缺少的定语，限制性定语从句前不用逗号隔开；非限制性定语从句只是对先行词的附加说明，如果去掉，先行词所述对象仍很清楚，非限制性定语从句前常用逗号隔开。这里有两个例句及分析：

Those who want to go camping please tell the monitor. 想去野营的人请告诉班长。（定语从句who want to go camping在句中不可少，否则先行词those不知道指谁，也就变得无意义，因此它是限制性定语从句。）

Football which is a very interesting game is played all over the world. 足球风靡全世界，它是一项很有趣的运动。（定语从句which is a very interesting game只是对意义已很明确的football作一个补充说明，因此它是非限制性定语从句。）

注意，非限制性定语从句可以用关系代词which who whom whose as及介词 which/whom等引导，也可以用关系副词when where引导，但不能用that引导。另外，非限制性定语从句中的关系代词或关系副词是不能省略的。

6)whom的用法

只有作定语从句中的宾语时才能用whom；介词后用whom不用who。口语中whom前无介词时可用that或who代替。

My brother whom you met the other day has gone abroad. 前几天你遇见过的我的那个兄弟，出国去了。

I have a few friends whom I could ring to see if they are free. 我有几个朋友，我可以打电话去联系，看看他们是不是有时间。

You have many people around you who are kind to you but whom you will soon forget. 你周围有许多对你好的人，但你都会很快忘记他们。

There came a lot of children most of whom I didn’t know. 来了许多孩子，大多数我都不认识。

7)介词＋which/whom引导的定语从句

如果关系代词which/whom本身在定语从句中充当一个介词或介词短语的宾语的时候，有时可以将介词直接放在which/whom的前面，这样就产生了“介词＋关系代词”及“名词或代词＋介词＋which/whom”或“复合介词＋which/whom”等的结构。

I know the man to whom you talked just now. 我认识你刚才与之说话的那个人。

Life is a flower of which love is honey. 人生是花朵，爱情是花蜜。

He was educated at the local grammar school after which he went on to Cambridge. 当在当地的一所中学上学，此后就去上了剑桥大学。

It’s a family of five children all of whom are studying music. 这一家有五个孩子，他们都在学音乐。

In the attic we found some apples none of which was fit to eat. 在阁楼里我们发现了一些苹果，其中没有一个能吃的。

I have three brothers all of whom have gone abroad. 我有三个兄弟，他们都出国了。

Soon they spotted a mountain on top of which stood a temple. 不久他们发现了一座山，山顶上有一座庙宇。

8)why引导的定语从句

关系副词why用在reason之后，只引导限制性定语从句，why在从句中作状语，表示原因。

Give me the reason why you should be interested in his affairs. 告诉我你为什么竟对他的事这样感兴趣。

The reason why she was ill was that she had eaten bad meat. 她生病的原因是她吃了变质的肉。

That is the reason why he raised the question. 这就是他所以提出问题的原因。

注意：有时reason后不一定是why引导的定语从句。如下列句子中，reason后接的是which/that引导的定语从句，这是因为，reason在定语从句中作主语或宾语。

Is this the reason which/that the chairman gave at the meeting? 这就是主席在会上所给的理由吗？

I really can’t understand the reason that/which he explained. 我实在无法理解他所解释的理由。

9)where引导定语从句有时修饰一些具有抽象意义的表示地点的名词，如situation point position等等。

If you are ever in a situation where someone starts shooting drop to the ground. 如果你遇到有人要射击的情况就摔倒在地上。

But after a few days’ stay they got to the point where they could read each other's thoughts. 不过呆了几天之后，他们到了一个彼此能理解相互想法的阶段。

It got to the point where I couldn't remember any of the reasons I loved him. 到那时候，我无法记起我爱他的任何理由了。

10)the way后的定语从句

The way后的定语从句用in which引导，in which可以用that代替，而that又可以省略。所以，表达“某人做某事的方法”有三种形式：

1. the way in which somebody does something

2. the way that somebody does something

3. the way somebody does something.

11)which指代前面的句中的内容

which的这一用法只能以非限定性定语从句出现。

Jenny was late for school a third time during the week which made her teacher very angry. 詹妮一周内第三次迟到了，这使得她老师很生气。

?He left early which was wise. 他早早地离开，那是很明智的。

He suddenly became wealthy which changed his whole mode of life. 他忽然变得富有了，这改变了他整个的生活方式。

He often helps me with my lessons which is kind of him. 他经常在功课方面帮助我，真是感谢他。

12)which作关系限定词的情况

which作为关系限定词时，其本身代替前面所陈述的内容。

She asked me to see the doctor which advice I took at once. 她要我去看医生，我立即采纳了她的建议。

He is studying economics which knowledge is very important today. 他正在攻读经济学，这门知识在今天是非常重要的。

He believes in students’ doing more homework which idea I am quite opposed to. 他相信要让学生做更多的家庭作业，我非常反对这个观点。

which的这种用法常伴随介词而用。常见的词组形式有by which means during which time in which case for which mistake for which reason等等。

She may have missed the train in which case (=if this happens) she won't arrive for another hour. 她也许没赶上火车，如果那样的话，她一小时是到不了的。

I called him by the wrong name for which mistake I apologize. 我叫错了他的名字，为此我道歉。

He didn’t feel well that morning for which reason he didn’t attend school. 那天早晨他感到不舒服，因此，他没去上学。

Tom spent four years in college during which time he learned French. 汤姆在大学上了四年学，在这段时间里，他学会了法语。

13)as用法

关系代词as引导定语从句有两种形式：

（1）as引导一个非限制性定语从句修饰一个分句，as代表该分句所表达的整个概念或其中一部分的概念。as定语从句可置于句首、句中或句尾；as本身在从句中充当主语、宾语及表语。

（2）用于as … as the same … as so … as such … as等结构中。

as用法的第一种情况：

As is known to all the earth moves around the sun. 众所周知，地球围绕太阳旋转。

He must be an African as may be seen from the colour of his skin. 他准是个非洲人，这可以从他的肤色看得出来。

If he comes late as is usual for another time we’ll not receive him. 如果他再一次像以往那样迟到，我们就不接待他了。

She is a fine singer as her mother used to be. 她是个很出色的歌唱家，像她的母亲当年一样。

As you will find out all is now settled. 你会发现，现在一切都解决了。

Helen is somewhat crazy as everyone could see. 海伦有些神经错乱，这种情况每个人都看得出。

注意这一类的as表面上看好像和which代替全句时的用法相似，但as引导的定语从句的最大特点是它的意思多侧重于表达“（正）像……、（正）如……”及类似的意思。一般说来，当关系代词在从句中作be动词的主语或一般动词的宾语时，which和as可交替使用；当关系代词在从句中作一般动词（非be动词）的主语时，只能用which；as可置于句首、句中，而which则不能。例如：

He was late for school as/which was usual with him. 他上学迟到了，他经常这样。

He saw the girl as/which he had hoped (he would). 他见到了那位姑娘姑娘，正像他希望的那样。

He saw the girl which delighted him. 他见到了那位姑娘，这使得他很开心。（句中的which不能用as代替，因为从句中的delighted是非be动词）

As has been said before grammar is not a set of dead rules. 正如上面所说的那样，语法不是一套死的规则。（句中的As不能用Which代替，因为此定语从句置于句首）

as用法的第二种情况：

There’s as good fish in the sea as ever came out of it. 海里有的是鱼；天涯处处有芳草。

Here is so big a stone as no man can lift. 这是一块没人能搬动的大石头。

Her manner and attitude toward him were quite the same as they had always been. 她对他的举止和态度和往常是完全相同的。

He does not possess such a mind as is necessary to a scientist. 他缺乏科学家所必须具备的头脑。

A man such as he will surely succeed. 像他这样的人是肯定会成功的。

I haven’t much money but you can use such as I have. 我钱不多，可你能用我所有的钱。

Such as you see is all we have. 你所见到的就是我们所有的东西。

14)介词 whom/which to do的类定语从句结构的不定式用法

This is a useful tool with which to cut steel. 这是可以用来切割钢材的工具。

Can you recommend someone from whom to learn how to use the software? 你能推荐一个可以向他讨教使用这一软件的人吗？

It’s not a room in which to live comfortably. 这不是可以舒适居住的房间。

这一结构的介词位置固定，不可移到动词之后，如第一句中的with which to cut steel不可改成which to cut stell with。

15)嵌入式定语从句

有一种定语从句，在其从句中的主语和谓语之间有一个插入语如I think。这一种定语从句叫做嵌入式定语从句。嵌入的分句的谓语动词常常是think believe guess imagine say suppose be sure doubt等等。

She offered a suggestion which she said would interest you. 她提出一个她说一定会引起你兴趣的建议。

He wrote letters to every person and organization that he believed might be able to help. 他写信给每个人和每个组织，他相信可能有帮助。
