定语从句(完整版)

1、定语从句（完整版）一） 限定性定语从句1. that既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，这些词包括当先行词是anything, everything, nothing

2、(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 ar

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.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与 of which 调换,表达的意思一

4、样.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There is somebody here who wants to speak to you. 这里有人要和你说话。（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

5、当于in which, at which, for which或at whichAttitudes 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 arri

6、ved 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 perso

7、n (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

8、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

9、 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 lik

10、e 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/

11、which) you asked for.(4) Tomorrow I will bring here a magazine for which you asked.(5) Well go to hear the famous singer (whom/that/who) we have often talked about.(6) Well 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) Th

12、is 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 with that you talked is my friend. (F)(3) The plane in which we flew

13、 to Canada is very comfortable. (T)(4) The plane in that we flew in to Canada is very comfortable.

14、ich 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

15、 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 dont 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 cle

16、ar,(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。不及物动词后面无宾语，就必须要求用关系副词或者是介词加关系代词；而及物动词后接宾语，则要求用关系代词。例如：This is the mountain

17、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 visit

18、ed 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 ago?A. whereB. that C. on which D. the one例2. Is this the museum _ the ex

19、hibition was held?A. whereB. that C. on whichD. 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whe

20、re，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 ,where和why 互换。 Thi

21、s 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?This is the reason why he came late.This is the reason for which he came late.（八）先行词和关系词二合一1)Whoever spits

22、 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引导的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

23、 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. whichD. 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 cou

24、ld expect.A. whatB. whichC. thatD. 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. thatB. whichC. 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

25、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；suchas 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, s

26、moking 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

27、 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 w

28、ay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an

29、ything, 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)

30、 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 wont 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

31、 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-

32、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：1As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

33、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 dont believe.注意：当

34、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

35、意思不同(4) She wore the same dress that she wore at Marys 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) Th

36、ere are very few but understand his idea.( but= who dont )(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 colle
