英语定语关系词

一、定语从句的概念

在复合句中，修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面。

二、定语从句的关系词

引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that， which， who（宾格whom，所有格whose），as等；关系副词包括where， when， why等。关系代词和关系副词放在先行词及定语从句之间起连接作用。关系词起3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。

本单元学习关系代词引导的定语从句。

1. who 指人，在从句中做主语

The boys who are playing football are from Class One.

Yesterday I helped an old man who lost his way.

2. whom 指人，在定语从句中充当宾语，常可省略

Mr. Liu is the person (whom) you talked about on the bus.

Mr. Ling is just the boy whom I want to see.

注意：关系代词whom在口语和非正式语体中有的时候常用who代替，并且可以省略。如：

The man who/whom you met just now is my friend.

3. whose 通常指人，也可指物，在定语从句中做定语

He has a friend whose father is a doctor.

I once lived in a house whose roof has fallen in.

whose指物时，常用以下结构来代替：

The classroom whose door is broken will soon be repaired.→ The classroom the door of which is broken will soon be repaired.

Do you like the book whose cover is yellow?→ Do you like the book the color of which is yellow?

4. which 指物，在定语从句中做主语或者宾语，做宾语时可省略

Football is a game which is liked by most boys.

This is the pen (which) he bought yesterday.

5. that 指人时，相当于 who 或者 whom ；指物时，相当于 which 。在定语从

句中做主语或者宾语，做宾语时可省略

The number of the people that/who visit the city each year rises one million.

Where is the man that/whom I saw this morning?

The number of people who/that lost homes reached 250,000．

It sounded like a train which/that was going under the house．

The boy（whom/that/who）we saw yesterday was John’s brother．

The car（which/that）my uncle just bought was destroyed in the earthquake．

关系代词代替先行词在定语从句中充当主语、宾语、定语，因此定语从句不能再出现关系代词所替代的名词或代词。如：

（误）The story（that/which）you told me it yesterday is interesting．

（正）The story（that/which）you told me yesterday is interesting．

昨天你给我讲的那个故事很有趣。

That 和which在定语从句中指物时，常常可以互换。但下面几种特殊情况，不能互换，只能用that, 不用which.

1）先行词被序数词或形容词最高级所修饰，或本身是序数词、基数词、形容词最高级时，只能用that，而不用which. 例如：

He was the first person that passed the exam.

他是第一个通过考试的人。

2）被修饰的先行词为all， any， much， many， everything， anything， none， the one等不定代词时，只能用that，而不用which. 例如：

Is there anything that you want to buy in the shop？

你在商店里有什么东西要买吗？

3）先行词被the only， the very， the same， the last， little， few 等词修饰时，只能用that，而不用which. 例如：

This is the same bike that I lost.

这就是我丢的那辆自行车。

4）先行词里同时含有人或物时，只能用that， 而不用which.例如：

I can remember well the persons and some pictures that I saw in the room.

我能清楚记得我在那个房间所见到的人和一些照片。

5）以who或which引导的特殊疑问句，为避免重复，只能用that. 例如：

Who is the girl that is crying？

正在哭泣的那个女孩是谁？

6）主句是there be 结构，修饰主语的定语从句用that，而不用which.例如：

There is a book on the desk that belongs to Tom.

桌子上那本书是汤姆的。

【拓展】定语从句关系词成分

关系代词：who , whom , whose , which , that 等。

who用于代替"表示人的意义"的先行词，并且在从句中作主语；在现代英语里，也可取代whom在从句中作动词的宾语。

例如：I have no idea about the man who wrote the article .我不认识写这篇文章的那个人。

The little boy who is singing there can recite quiet a number of Chinese poems .

whom 用于代替"表示人的意义"的先行词，并且在从句中作动词或介词的宾语。在现代英语里，如果whom在从句中作动词的宾语，它与who可以通用；但是如果whom在从句中作介词的宾语，那么就只能用whom而不能与who通用了。当然，如果在口语或非正式文体中，介词没有提前，也就没有这点要求了。例如：Who is the girl whom ( who ) you talked to just now ? 刚才和你说话的那个女孩子是谁？

Yesterday, I happened to meet , in the shopping center , the professor who ( whom ) I got to know at a party .

昨天在购物中心，我碰巧遇见了那位我在一次聚会上认识的教授。

They are looking for the patient on whom doctors just performed an operation . 他们正在寻找那位医生刚刚给他做过手术的病人。

(句中的关系代词whom代替the patient ，在从句中作介词on的宾语，而且介词on提到关系代词的前面，所以who 和whom就绝不可以通用了，此处只能用whom 。)

Who is the girl to who (whom) you talked just now ? （错误）(句中的`关系代词whom(who)代替the girl ，在从句中作介词to的宾语，但是由于介词to已提到了关系代词的前面,who 和whom就绝不可以通用了,所以如果还继续使用who句子就错了。此处只能用whom 。)whose 用于代替"表示人或物意义"的先行词，在从句中作定语，往往与它所修饰的名词一起构成一个名词短语在从句中担当成分。Whose常表达"某人的、某物的"之意。

例如：Do you know the name of that girl whose brother is your roommate ?你知道她的哥哥与你同寝室的那位女孩的名字吗？

Water whose boiling point is at 100 degree Centigrade has no color, no flavor. 沸点在摄氏100度的水无色、无味。which 用于代替"表示事物意义"的先行词，在从句中作主语、宾语。

例如：Views which are entirely new or foreign may also be hard to accept .那些全新的或是来自国外的观点或许也很难被接受。

I've got a novel which you may like to read .我弄到一本你或许想看的小说。

That was a fault which could not be forgiven . 那是不能饶恕的错误。that 既用于代替"表示人的意义"的先行词，也用于代替"表示事物意义"的先行词；在从句中既可以作主语，也可以作谓语动词的宾语，但是不能作介词的宾语。在一定范围内，that = who / whom / which 。例如：Views that (which ) are entirely new or foreign may also be hard to accept .那些全新的或是来自国外的观点或许也很难被接受。

Salaried people that ( who) earn more than a few thousand dollars must pay a certain percentage of their salaries to the federal government .工薪在几千美元以上的人必须将工资中的一定百分比交付给联邦政府。

Who is the girl to that you talked just now ? （错误）要点提示：定语从句中作宾语的关系代词可以省略;如果关系代词在定语从句中作宾语可以省略。例如：This is the book ( which ) you were looking for yesterday . 这就是你昨天找的那本书。

I don't like the novel ( that ) you are reading .我不喜欢你看的这本小说。

Who is the man ( whom ) you're talking about ? 你们谈论的那个人是谁？

定语从句中，关系代词的单复数取决于先行词的单复数。

例如：Those who are in their forties are required to have a physical examination this afternoon .（先行词Those是复数，关系代词who也就看作是复数，所以从句的谓语动词就用了复数形式are了。）请那些年龄在四十几岁的人于今天下午去进行体检。

This is the magazine which was sent to me by post .（先行词the magazine是单数，关系代词which也就看作是单数，所以从句的谓语动词就用了单数形式was sent） 这是通过邮局寄给我的杂志。

定语从句中关系词分类有几种

定语从句及相关术语1.定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。2.关系词：引导定语从句的关联词成为关系词关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。关系词常有3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。（序）1 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来担任，也可以由一个句子来担任． 定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句．2 定语从句用来修饰名词，代词或整个主句．3 定语从句分为限定性和非限定性从句两种。4 定语从句存在的条件:先行词+关系词（有的版本作关联词）+从句（一） 限定性定语从句1. that即可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置 2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略 4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语 5. where是关系副词，用来表示地点的定语从句 6. when引导定语从句表示时间〔注〕值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导 By the time you arrive in London, we will have stayed there for two weeks. I still remember the first time I met her. Each time he goes to business trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc. 7. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格 8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导 （二）非限定性定语从句非限定性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立 1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分 2. 在引导限定性定语从句时，that有时相当于in which, at which, for which或at which Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。 I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐，而他恰恰与我相反。 We arrived the day that(on which) they left. 刚好我们到的那天他们走了。3. 有时as也可用作关系代词4. 在非限定性定语从句中，不能用that，而用who, whom代表人，用which代表事物.（三）关系代词引导的定语从句1.who指人，在从句中做主语(1) The boys who are playing football are from Class One.(2) Yesterday I helped an old man who lost his way.2. whom指人，在定语从句中充当宾语，常可省略。(1) Mr. Liu is the person (whom) you talked about on the bus.(2) Mr. Ling is just the boy whom I want to see.注意：关系代词whom在口语和非正式语体中常用who代替，可省略。(3) The man who/whom you met just now is my friend3.which指物，在定语从句中做主语或者宾语，做宾语时可省略(1) Football is a game which is liked by most boys.(2) This is the pen (which) he bought yesterday. 如果在从句中做宾语,就用whom或who.比如: He is the man whom/who I talk to. 如果是在从句中作主语就只能用who.比如: He is the man who has an English book.4. that指人时，相当于who或者whom；指物时，相当于which。在定语从句中做主语或者宾语，做宾语时可省略。(5) The number of the people that/who come to visit the city each year rises one million.(6) Where is the man that/whom I saw this morning?5. whose通常指人，也可指物，在定语从句中做定语(1) He has a friend whose father is a doctor.(2) I once lived in a house whose roof has fallen in.whose指物时，常用以下结构来代替(3) The classroom whose door is broken will soon be repaired.(4) The classroom the door of which is broken will soon be repaired.(5) Do you like the book whose cover is yellow?(6) Do you like the book the color of which is yellow?（四）注意介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时从句常由介词+关系代词引导(1) The school (that/which) he once studied in is very famous.(2) The school in which he once studied is very famous.(3) Tomorrow I will bring here a magazine (that/which) you asked for.(4) Tomorrow I will bring here a magazine for which you asked.(5) We’ll go to hear the famous singer (whom/that/who) we have often talked about.(6) We’ll go to hear the famous singer about whom we have often talked.注意：1. 含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等(1) This is the watch which/that I am looking for. (T)(2) This is the watch for which I am looking. (F)2. 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose(1) The man with whom you talked is my friend. (T)(2) The man who/that you talked with is my friend. (F)(3) The plane in which we flew to Canada is very comfortable. (T)(4) The plane in that we flew in to Canada is very comfortable. (F)3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词(1) He loved his parents deeply, both of whom are very kind to him.(2) In the basket there are quite many apples, some of which have gone bad.(3) There are forty students in our class in all, most of whom are from big cities.（五）关系副词引导的定语从句1. when指时间，在定语从句中做时间状语(1) I still remember the day when I first came to the school.(2) The time when we got together finally came.2. where指地点，在定语从句中做地点状语(1) Shanghai is the city where I was born.(2) The house where I lived ten years ago has been pulled down.3. why指原因，在定语从句中做原因状语(1) Please tell me the reason why you missed the plane.(2) I don’t know the reason why he looks unhappy today.注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换(1) The reason why/ for which he refused the invitation is not clear,(2) From the year when/in which he was going to school he began to know what he wanted when he grew up.(3) Great changes have taken place in the city in which./where I was born. （六）判断关系代词与关系副词 方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如： This is the mountain village where I stayed last year. I'll never forget the days when I worked together with you. 判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。） （错） This is the mountain village where I visited last year. （错） I will never forget the days when I spent in the countryside. （对） This is the mountain village (which) I visited last year. （对） I'll never forget the days (which) I spent in the countryside. 习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。 方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。例1. Is this museum ___ you visited a few days age? A. where B. that C. on which D. the one例2. Is this the museum ____ the exhibition was held. A. where B. that C. on which D. the one答案：例1 D，例2 A例1变为肯定句： This museum is ___ you visited a few days ago.例2变为肯定句： This is the museum ___ the exhibition was held. 在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。 而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A。 关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语) 。 （七）介词+关系词1）介词后面的关系词不能省略。2）that前不能有介词。3） 某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。 This is the house in which I lived two years ago. This is the house where I lived two years ago. Do you remember the day on which you joined our club? Do you remember the day when you joined our club? （八）先行词和关系词二合一 1)Whoever spits in public will be punished here. (Whoever 可以用 anyone who 代替) 2)The parents will use what they have to send their son to technical school. (what 可以用all that代替) （九as） which 非限定性定语从句 由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。 As we know, smoking is harmful to one's health. The sun heats the earth, which is very important to us. 典型例题1）Alice received an invitation from her boss, ___came as a surprise.A. it B. that C. which D. he 答案C. 此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选he句意不通。2）The weather turned out to be very good, ___ was more than we could expect.A. what B. which C. that D. it 答案B。which可代替句子，用于非限定性定语从句，而what不可。That 不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。3）It rained hard yesterday, ____ prevented me from going to the park..A. that B. which C. as D. it 答案B. as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点： (1） as 引导的定语从句可置于句首，而which不可。 (2） as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。 在本题中，prevent由于是行为动词，所以正确选项应为B。As 的用法例1. the same… as；such…as 中的as 是一种固定结构, 和……一样……。 I have got into the same trouble as he (has).例2. as可引导非限制性从句，常带有'正如'。 As we know, smoking is harmful to one's health. As is know, smoking is harmful to one's health. As是关系代词。例1中的as作know的宾语；例2中，它充当从句的主语，谓语动词know要用被动式。 （十）关系代词that 的用法(1)不用that的情况 (a) 在引导非限定性定语从句时。(错)The tree, that is four hundred years old, Is very famous here. (b) 介词后不能用。 We depend on the land from which we get our food. We depend on the land that/which we get our food from.(2) 只能用that作为定语从句的关系代词的情况 (a) 在there be 句型中，只用that，不用which。 (b) 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。 (c) 先行词有the only, the very,the same,the last,just修饰时，只用that。 (d) 先行词为序数词、数词、形容词最高级时，只用that。. (e) 先行词既有人，又有物时。(f) 先行词指物，在主句中作表语时．(g) 为了避免重复．(h)先行词是the way时举例：Is this the book that you borrowed in the library?这是你在图书馆借的那本书吗？Who that break the window should be punished．谁打碎了窗户都要受到惩罚． All that is needed is a supply of oil. 所需的只是供油问题。 Finally, the thief handed everything that he had stolen to the police. 那贼最终把偷的全部东西交给了警察。（十一）难点分析（一）限制性定语从句只能用that的几种情况1．当先行词是anything, everything, nothing (something 除外), few, all, none, little, some等代词时，或者是由every, any, all, some, no, little, few, much等修饰时(1) Have you taken down everything that Mr. Li has said?(2) There seems to be nothing that seems impossible for him in the world.(3) All that can be done has been done.(4) There is little that I can do for you.注意：当先行词指人时，偶尔也可以用who(4) Any man that/.who has a sense of duty won’t do such a thing.2. 当先行词被序数词修饰(1) The first place that they visited in London was the Big Ben.3. 当先行词被形容词最高级修饰时(1) This is the best film that I have seen.4. 当形容词被the very, the only 修饰时(1) This is the very good dictionary that I want to buy,(2) After the fire in his house, the old car is the only thing that he owned.当先行词指人时，偶尔也可以用who(3) Wang Hua is the only person in our school who will attend the meeting？5. 当先行词前面有who, which等疑问代词时(1) Who is the man that is standing there?(2) Which is the T-shirt that fits me most?6. 当先行词既有人，也有动物或者物体时(1) Can you remember the scientist and his theory that we have learned?（二）关系代词as和which引导的定语从句as和which引导非限制性定语从句，有相同之处也有不同之处。具体情况是：1．As和which都可以在定语从句中做主语或者宾语，代表前面整个句子。(1) He married her, as/which was natural.(2) He was honest, as/which we can see.2. as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思(1) As is known to all, China is a developing country.(2) He is from the south, as we can see from his accent.(3) John, as you know, is a famous writer.(4) He has been to Paris more than several times, which I don’t believe.注意：当主句和从句存在逻辑上的因果关系时，常用which(5) Tom was always late for school, which made his teacher angry.3. 当先行次受such, the same修饰时，常用as(1) I have never heard such a story as he tells.(2) He is not such a fool as he looks.(3) This is the same book as I lost last week.注意：当先行词由the same修饰时，偶尔也用that引导定语从句，但是和由as所引导的定语从句意思不同(4) She wore the same dress that she wore at Mary’s wedding. 她穿着她在MARY婚礼上穿过的一条裙子。(5) She wore the same dress as her young sister wore. 她穿着和她妹妹所穿的一样的裙子。(三）以the way为先行词的定语从句通常由in which, that引导，而且通常可以省略。(1) The way in which/ that/./ he answered the question was surprising.(四) but有时也可以做关系词引导定语从句(1) There are very few but understand his idea. ( but= who don’t )(五) 区分定语从句和同位语从句1．定语从句修饰先行词，它和先行词是修饰关系；同位语从句说明先行词的具体内容，是补充说明的关系(1) The plane that has just taken off is for London. 定语从句(2) The fact that he has been dead is clear. 同位语从句2．定语从句由关系代词或者关系副词引导，关系词在句中充当成分，有时可以省略；同位语从句主要由that引导，在句中一般不做成分；句子也可以由when, where, how, why, whether, what等词引导，充当成分(1) The news he told me is true.(2) The news that he has just died is true.(3) The problem that we are facing now is how we can collect so much money. 定语(4) The problem how we can collect so much money is difficult to solve.3. 同位语从句和先行词一般可以用be动词发展成一个完整的句子，而定语从句不可以(1) The idea that we could ask the teacher for advice is wonderful. 同位语(2) The idea was that we could ask the teacher for advice.(3) The fact that the earth moves around the earth is known to all.(4) The fact is that the earth moves around the earth.

关系代词有who,whom,that,which,whose,关系副词有where(地点）,when（时间）,why（原因）.总体来说关系副词在定语从句中做状语 他们和关系代词主要的区别是where,when,why=介词 whicheg:This is the house in which (where) I lived last year.This is the reason for which (why) he was late for school.That's the day on which (when) I met him in the street.关系词的选择依据在从句中所作的成分,先行词在从句中作主、定、宾语时,选择关系代词（who,whom,that,which,whose）；先行词在从句中做状语时,应选择关
