定语从句(relative clause)
一、定语从句的定义
在复合句中，修饰某一名词或代词，充当定语的从句叫定语从句
e.g: The man is a worker .
The man is speaking at the meeting.
The man who is speaking at the meeting is a worker.
二、先行词和关系词
被定语从句修饰的名词或代词叫先行词，引导定语从句的词叫关系词，关系词一般紧跟在先行词之后。
关系词分为关系代词和关系副词，关系代词有that, which, who, whom. whose, 关系副词有when, where, why.
三、关系代词的用法
关系代词在定语从句中要充当句子成分，如主语、宾语、表语、定语等。
1.who, whom 的用法
who, whom都指人，who在从句中作主语或宾语，whom在从句中作宾语，有时候可用who代替whom.
e.g: The family who/whom I met at the airport were very kind.
The people who called yesterday want to buy the house.
注：若whom在从句中作介词的宾语，且介词置于whom之前时，不能用who代替。
e.g: Do you remember the boy with whom I used to go out?
2. whose的用法
Whose可以指人，也可以指物，在从句中作定语。
e.g: He is a man whose opinion I respect.
He has a beautiful house whose door is red.
3.which的用法
which指物，通常在从句中做主语或宾语。
e.g: He prefers groups which/that play quiet and slow songs.
4. that的用法
That既可以指人，也可以指物。在句作主语、宾语、表语。
e.g: The watch that/which you give me keeps perfect time.
The people that/who/whom I talk to were from my hometown.
注：1 .that作介词的宾语时，介词不可以提到that的前面，若介词提前则用whom或which.
The boy that I go to school with is my neighbor.(对)
The boy with that I go to school is my neighbor.（错）
The boy with whom I go to school with is my neighbor.（对）
2.在定语从句中，关系代词who, whom，which作宾语时，可以省略不写。
3.在定语从句中，作有些“动词+介词”组成的短语动词的宾语时，介词
不能提到关系代词之前。
e.g：The child whom aunt Li takes care of is ill.
四、关系副词的用法
关系副词用来引导说明时间、地点、和原因的定语从句，主要有when, where, why，它们在从句中充当状语，通常不能不省略。
1.when 的用法
when指时间，在从句中作时间状语。此时常用in which, on which, at which, during which等代替。
e.g.：I still remember the day when/on which I first came to Beijing.
2. where 的用法
where指地点，在从句中作地点状语。此时常用in which, on which, at which, 等代替。
e.g: This is the town where/in which I was born.
3. why 的用法
why指原因，在从句中作原因状语。它的先行词通常是reason。此时用for which等代替。
e.g: Is this the reason why/for which he refused our help?
五、有关定语从句的注意事项
1.主谓一致
若关系代词在从句中作主语，从句中谓语动词的单复数应与先行词保持一致。
e.g: After school, she often helps the students who are not good at English.
2.宜用that的情况
1）序数词或形容词最高级修饰先行词时
e.g: This is the first play that I have seen since I came here.
2）先行词被every, some, no, all, any, little, much等修饰时
e.g: I’ve read all the books that you lend me.
3）everything, something, nothing, all, anything, little, much等不定代词作先行词时
e.g: Everything that we saw in this film was true.
4）先行词被the only, the very, the same, the last修饰时
e.g: This is the very book that belongs to him.
5）主句已有who或which时
e.g: Who is the girl that is standing under the tree?
6）当先行词同时指人和物时
e.g:I’ve never heard of the people and things that you talked about just now.

2020考研语法指导：定语从句详解 定语从句是英语学习的难点，也是考研英语考查的重点。掌握考研英语的定语从句需要掌握以下几个方面： 一、定义 定语从句是指在句中做定语作用，修饰句中的名词或代词的从句，其中被修饰的名词或代词为先行词。当关系代词作定语从句的主语时，其后的谓语动词的人称和数取决于先行词的人称和数。 二、定语从句的结构 定语从句一般位于先行词的后面，定语从句由关系代词who, whom, whose, that, which , that, as 和关系副词when, where, why 等引导。 一）关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中做主语时，从句谓语动词的人称和数要和先行词保持一致。 1） who, whom, that 这些词代替的先行词是人的名词或代词，在从句中做主语和宾语。例如：Is he the m an who/that wants to see you? 他就是你想见的人吗？（who/that在从句中做主语） He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中做宾语） （2） whose用作关系词表示所属格，也可看作是关系形容词，因 为它后面必须接一个名词连用。不能单独使用。例如:
? They rushed over to help the man whose car had broke n down. 那人车坏了，大家都跑过去帮忙。 (3) which, that所代替的先行词是事物的名词或代词，在从句中可做主语、宾语等。作宾语时常可省略。例如： ? A prosperitywhich / that had never been seen before appears in the countryside? 农村出现了前所未有的繁荣。(which / that在句中作宾语) 二)关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 (1)关系副词when, where, why的含义相当于“介词+ which ”结构，所以常常和“介词+ which ”结构交替使用。例如： There are occasionswhen (on which )one must yield? 任何人都有不得不屈服的时候。 Beijing is the placewhere in which ) I was born?北京是我的出生地。 Is this the reason why ( for which )he refused our offer? 这就是他拒绝我们协助他的理由吗？ (2)that代替关系副词，能够用于表示时间、地点、方式、理由的名词后取代when, where, why和“介词+ which ”引导的定语从句，在口语中that常被省略。例如：
定语从句 一、that引导的定语从句 1. that指人时，相当于who或whom；指物时，相当于which。 在定语从句中作主语或宾语，作宾语时常可省略。 He is the man that/who lives next door.他就是住在隔壁的那个人。 Where is the man(that/whom) I saw this morning? 我今天早上看到的那个人在哪儿？The person (that/whom) you introduced to me is very kind. 你介绍给我的那个人很友好。The season that/which comes after spring is summer.春天之后的季节是夏季。 I don’t like stories that/which have unhappy endings. 我不喜欢结尾悲伤的故事。 The dress(that/which) Ann bought doesn’t fit her very well.安买的衣服不太合身。 2.限制性定语从句中只能用that引导定语从句的情况 （1）当先行词为all, much, little, something, everything, anything, nothing, none, few, some, the one等词时。 Everything that he said was true. 他所说的一切都是真的。 There seems to be nothing that is impossible to him in the world. 对他来说似乎世界上没有什么不可能的事。 Is there anything that I can do for you? 有我能为你效劳的事吗？ That’s all that I know. 我知道的就这么多。 （2）当先行词被the very（恰恰,正好）the only, any, few, little, no, all修饰时。 This is the very grammar book (that) I want to buy. 这正是我要买的语法书。 The only thing that is constant is change. 唯一不变的是变化。 There was little that we could do to help her. 我们没有什么能帮助她的。 （3）当先行词是形容词最高级或被形容词最高级修饰时。 This is the best that has been used against pollution.这是曾经用过的最好的抗污染的办法。This is the most interesting film that I've ever seen. 这是我看过的最有趣的电影。 （4）当先行词是first，last，next等序数词或被序数词修饰时。 The first place that they visited in London was the Big Ben. 在伦敦他们参观的第一个地方是大本钟。 What is the first American film that you have seen? 你看过的第一部美国电影是什么？（5）当主句的主语是疑问词who或which时。 Who that has common sense will believe such nonsense? 有常识的人谁会相信这种无聊的
where引导的定语从句修饰抽象名词。 一、where定语从句修饰抽象名词point You reach a point where medicine can’t help. 你已到了药物无法治疗的地步。 The crisis has reached a point where the receiver will have to be called in. 危机已达到非把破产管理人叫来不可的地步。 We have reached a point where a change is needed. 我们到了必须改一改的地步。 注：有时point也可以是具体的地点： Let the point where AB cuts CD be called E. 设AB线与CD线的相交点为E。 The accident happened at the point where the A15 joins the M1. 事故发生在A15与M1交叉的十字路口。 二、where定语从句修饰抽象名词case There are cases where the word “mighty” is used as an adverb. 在一些情况下，mighty一词可用作副词。 Today, we’ll discuss a number of cases where beginners of English fail to use the language properly. 今天，我们将讨论一些英语初学者对英语使用不当的问题。 三、where定语从句修饰抽象名词activity Those successful deaf dancers think that dancing is an activity where sight matters more than hearing. 那些失聪的成功舞蹈演员们认为，舞蹈是一种让人看胜过让人听的活动。 四、where定语从句修饰抽象名词situation He got into a situation where it is hard to decide what is right and wrong. 他陷入一种难以分辨是非的局面。 If you risk something important, you cause it to be in a dangerous situation where you might lose it. 你如果拿重要的东西去冒险，那你就是将它置于一种可能会失去它的危险境地。 五、where定语从句修饰抽象名词position It’s put me in a position where I can’t afford to take the job. 这使我陷入一种不能接受此工作的境地。 六、where定语从句修饰抽象名词job
关于which引导从句的小结： 关系代词which 一般指物，在定语从句中作主语、宾语或定语，既可引导限制性定语从句，又可引导非限制性定语从句。 1. 引导限制性定语从句 A shop should keep a stock of those goods which sell best.

英语语法讲解之定语从句 时间：2016-08-12作者：来源：学习方法网 一．几个基本概念 1.定语从句的定义：用作定语的从句叫定语从句。 2.先行词：被定语从句所修饰的名词或代词。 3.定语从句的位置：紧跟先行词(名词或代词)之后。 4.引导词：引导定语从句的词(包括关系代词和关系副词)。 ﹙1﹚关系代词：that/who/whom/which/as ﹙2﹚关系副词：when/where/why 5.引导词的位置：位于定语从句之前(先行词之后)。【as除外】 6.引导词的功能(作用)： ﹙1﹚连接先行词和定语从句。 ﹙2﹚在定语从句中充当一定的成分(关系代词充当主语或宾语，关系副词充当状语)。 7.定语从句的类型： ﹙1﹚限定性定语从句(主句和定语从句之间无逗号)。 ①直接由引导词引导定语从句 The man who you’re talking to is my friend. ②由介词+关系代词(whom/which)引导 The man to whom you’re talking is my friend. I need a pen with which I can write a letter.
=I need a piece of paper on which I can write a letter. 介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。例如： The man (who/whom/that) I talked about at the meeting is from Beijing University. =The man about whom I talked at the meeting is from Beijing University. The palace (which/that) I often pay a visit to was built in the 17th century. =The palace to which I often pay a visit was built in the 17th century. ﹙2﹚非限定性定语从句(主句和定语从句之间用逗号隔开)。 ①直接由引导词引导定语从句。 ②由介词+关系代词(whom/which)引导。 I live in a house far away from the city，in front of which is a big tree. There is an apple tree standing at the gate，on which are many apples. This is the man to whom I gave the book. ③由“代词/名词+of+whom/which”或“of which/ whom +名词/代词”(先行词指 人用whom，指物用which)引导。One，some，any，none，all，both，several，many，most，neither，either等词、数词、分数或百分比与of whom或of which连用。 He has five children，two of whom are abroad. (比较：He has five children，and two of them are abroad.) We have three books，none of which is/are interesting. (比较：We have three books，but none of them is/are interesting.) 除why和that不能引导非限定性定语从句外，其余引导词都可以，用法同限定性定语从句一样。但要注意以下区别。
高中英语定语从句详解 Ⅰ、概念: (１) 定语从句:在主从复合句中用作定语得从句叫定语从句。定语从句一般紧接在先行词（antｅcedｅｎt)后面。 (2) 先行词:被定语从句修饰得成份。先行词可以为一个词,短语，或整个主句。 (3)引导定语从句得词叫关系词,分为关系代词与关系副词。 关系词得作用: 1) 引导定语从句，连接主句与从句,相当于一个连词; ２) 必在从句中作某个句子成份(可以做主语,宾语,表语,定语，状语) 常用得关系代词: ｔhat、wｈｉcｈ、wｈo、whom、wｈosｅ,当关系代词在定语从句中做宾语时，关系代词可以省略。 常用得关系副词(在从句中只作状语): when(时间状语）、why(原因状语)、wｈe ｒｅ（地点状语） 可以修饰人得关系代词:thａt, ｗho，wｈｏｍ,whosｅ 可以修饰事得关系代词:tｈat, whｉcｈ, as，whose, The studeｎt who answerｅd ｔhe ｑuestion was John、 Ｉkｎow thｅｒeasoｎwhy he wａｓso angｒy、 The bｏy （wｈom) ｙou are taｌkｉnｇｔo is myｂrotｈｅｒ、 Ｉ'd likｅ a ｒoｏｍwhose window fａｃesｔｈe sea、 定语从句三步： 第一找出先行词; 第二瞧先行词在定语从句中得语法功能（做主语、宾语、表语或状语); 第三选择合适得关系词。 Ⅱ、几个关系代词得基本用法: ●tｈat:可指人或物；在定语从句中作主语,宾语,表语。(指人时,相当于whｏ或wｈｏｍ;指物时,相当于whiｃh)（一般不用于非限制性定语从句；不可置于介词后作宾语) 如: 1、A lｅtteｒthaｔ／which is wrｉtｔen in peｎcｉl is diffiｃult ｔo ｒead、（主语) 2、Do yｏu kｎｏw tｈe gentleman ｔhａｔ/ｗｈｏspoke just ｎｏw? 3、Ｙou can takｅａnything ( ｔhat)you like、(宾语) 4、Whaｔｉs thｅquestiｏｎ(ｔhat/whｉｃh) they aｒｅｔalｋing about? 5、Hｅreｉs theｍan （wｈo／whom/ｔhat) yｏu want tｏsee、 6、Ｓhe＇s no longeｒthe girl( that) sｈeｕsｅd to ｂe befｏre、（表语） 7、Ｏuｒhometｏwn iｓno ｌonger ｔhｅoｎe (thａt)it usｅｄto ｂe、(=Ｏｕr homeｔｏｗn iｓｎot tｈe sａｍe as it uｓed tｏｂe、 = Our hｏmｅtｏwn is diffeｒenｔfrom what iｔｕｓｅｄtｏｂe。 =Ouｒhometｏｗn ｉs notｗhａt it uｓed to ｂe、) ●which：指物;在定语从句中作主语,宾语。如： 1、Thｅboｏk which/thａｔwas ｏn the ｄeｓkｗａsｂought bｙｍy fatｈer、(主语) 2、Tｈｅboｏk(whiｃh/tｈaｔ) Ｉｂｏught yesteｒdaｙｉs very
Where引导定语从句,先行词不一定都表 示地点 1、We will discuss a number of cases __ beginners of English fail to use the language preperly、A、which B、as C、why D、where 2、He was driving so fast as to get himself into a dangerous situation ___he is likely to lose the control over his car、 A、which B、as C、why D、where 两道题都选where ,但就是case, situation都不就是地点,如何理解？ 在“先行词不就是表示地点的名词”的前提下,如何判断就是否使用关系副词where来引导定语从句的问题就是一个高频考点。就就是说,关系副词where 所指代的先行词不只就是表示地点的名词。
用Where引导定语从句,先行词不一定都表示地点按照通常的理解,当where 引导定语从句时,它的先行词就就是表示地点的名词,但事实并不就是我们想象的那么简单。很多情况下,where所指代的先行词并不表示地点。请瞧以下几个例句: Other research, where siblings have been asked to say who their mother and father favor, suggests that mothers do tend to show a preference for their first-born son, but fathers often show great affection for their youngest daughters、 1、Remember that the best relationship is one where your love for each other is greater than your need for each other、请记住,最深的感情关系表现为彼此间的爱超过彼此间的需要。
Unit 9语法导学案：定语从句专题讲解 基本概念: 在复合句中，修饰某一名词或代词的从句叫定语从句 Do you know the man who spoke at the meeting just now? That is th^ouse where h e lived ten years ago. 定语从句所修饰的词叫先行词；定语从句一般用关系代词或关系副词来引导，关系词放在先 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）等，关系畐寸词包括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，同时又作定语 从句的重要成分。定语从句的谓语动词由先行词来决定。 三、定语从句的分类 根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性 定语从句。限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去，非限制性定语从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍完整。 四、关系代词的用法 时不可省略，作宾语可省略。例如： Mary likes music that is quiet and gentle玛丽喜欢轻柔的音乐。（that 作主语）The coat （that）I put on the desk is blue我放在桌子上的那件外套是蓝色的。 （that作宾语） 2. which用于指物，在句中作主语或宾语，作主语不可省略，作宾语可省略。例如： The buildi ng which sta nds n ear the train stati on is a supermarkets 于火车站附近的那

、先行词指人,在句中作主语who: John,who is only five,has an inborn talent for music. (约翰是一外5岁大的孩子,有着天生的音乐才能。) 2、先行词指人,在句中作宾语whom: His wife,whom you met at my home,was a teacher. (他的妻子，就是你在我家遇见的那个，是一位老师。) 3、先行词指物,在句中作主语或宾语which: Her house,which was built a hundred years ago,stood still in the earthquake.(那座房子在地震中依然耸立，它是一百多年前建造的。) 注意：无论先行词指人或者指物,在句中作主语或者作宾语，非限制性定语从句的引导词都不能用that。 4、先行词在句中作定语，无论指人或者指物,引导词都用whose: The girl,whose name is Kate,is the top of the students in our school.(那个女孩是我们学校最优秀的学生，她的名字叫Kate。) The book,whose cover is red,is mine.(封面是红色的那本书是我的。) 5、先行词指物，在句中作时间状语用when： The sports meeting will be put off till next month,when we will have made all the preparations.(运动会将被推迟到下个月，那时我们做好一切准备。) 6、The next day we arrived in New York,where we were inerviewed on the radio.（第二天我们到达纽约，在那里我们接受了电台的采访。） 7、如果先行词作介词的宾语，先行词指人，介词提前的结构是：介词＋whom；先行词指物，介词提前的结构是：介词＋which: President Wilson,with whom he had not the same intimate relations,is treated much less sympathetically.(威尔逊总统与他没有同样的亲密关系，所以就没有被很同情地对待。) The Second World War,in which millions of people were killed,ended in 1945.(第二次世界大战造成数百万人的死亡，于1945年结束。) 8、as也可以引导定语从句，常与such连用： Such people as you describe are rare nowadays.(象你所描绘的那种人现在已经很少见了。) Let's disscuss only such questions as concern us.(让我们只讨论那些和我们有关的问题吧。) 注意：the same that+从句，意思是：正是那一个人或物；the same as+从句，意思是：就像某个人或物： He is the same man that you are looking for.(他就是你要找的那个人。) He is the same man as you met in the street.(他很象你昨天在街上遇见的那个人。实际上并不是那个人。) This is the same pen that I lost yesterday.(这就是我昨天丢失的那支笔。) This is the same pen as I lost yesterday.(这很像昨天我丢失的那支笔。)
定语从句 定语从句及相关术语 1.定语从句：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，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称为关系词，关系词有关系代词和关系副词。关系代词有that, whi ch, 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。 注：关系代词有主语.宾语之分。一般whom作为宾语。 4.定语：定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语或句子，汉语中常用‘……的’表示。主要由形容词担任。此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任．单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。 先行词：被定语从句修饰的名词、代词称为先行词。 （一）限定性定语从句 一、关系代词（在句中作主语、宾语或定语） 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在从句中作宾语也可以省略。[eg：this is the book （which）you want。]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anyt hing, everything, nothing , none等不定代词时，或者是由every, any, all, some, no, little, few, muc h等修饰时等，这时的that常被省略还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that 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. 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,表达的意思一样。 二、关系副词（在句中作状语） 关系副词=介词+关系代词 why=for which where=in/ at/ on/ ... which (介词同先行词搭配) when=during/ on/ in/ ... which (介词同先行词搭配) 1. where是关系副词，用来表示地点的定语从句。 2. 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.

Unit 9 语法导学案：定语从句专题讲解 一、基本概念： 在复合句中，修饰某一名词或代词的从句叫定语从句。 Do you know the man who spoke at the meeting just now? That is thehouse where h e lived ten years ago. 定语从句所修饰的词叫先行词；定语从句一般用关系代词或关系副词来引导，关系词放在先行词与定语从句之间起连接作用，同时又作从句中的一个成分。引导定语从句的关系代词有： that, who, whom, whose, which， as 关系副词有： when, where, why. 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）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，同时又作定语从 句的重要成分。定语从句的谓语动词由先行词来决定。三、定语从句的分类 根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定 语从句。限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去，非限制性定语从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍 完整。 四、关系代词的用法 关系代词指代在定语从句中的作用that既指人，也指物主语、宾语 which指物（相当于 that）主语、宾语 who指人（相当于 that）主语 whom指人宾语 whose既指人，也指物定语 1.that 既可以用于指人，也可以用于指物。在从句中作主语或宾语，作主语 时不可省略，作宾语可省略。例如： Mary likes music that is quiet and gentle玛.丽喜欢轻柔的音乐。（ that 作主语）The coat （that） I put on the desk is blue我.放在桌子上的那件外套是蓝色的。（that 作宾语）
which引导的定语从句的用法 WHICH可以引导定语从句，修饰表示事物的先行词，在定语从句中充当主语、宾语或者表语。例如：HEWASREADINGABOOK， WHICHWASABOUTWAR.他正在读一本关于战争的书。（关系代词WHICH在修饰BOOK的定语从句中充当主语。） HEWASREADINGABOOK，WHICHHEHADBOUGHTFROMLONDON.他正在读一本书，这本书是从伦敦买回来的。（关系代词WHICH在修饰BOOK的定语从句中充当宾语。） WHICH引导非限定性定语从句时有一个特殊用法，即它所引导的非限定性定语从句修饰主句中更多的部分甚至整个主句（这时被定语从句所修饰的“先行词”要作广义理解），WHICH仍在定语从句中作主语、宾语或表语。例如：HESETFREETHEBIRDSHAPPILY， WHICHWASACELEBRATIONFORHISSUCCESS.他开心地把鸟放了，这是对他成功的一种庆祝。 把非限定性定语从句“WHICHWASACELEBRATIONFORHISSUCCESS”的先行词视为主句中的“THEBIRDS”显然不符合整句的语境，被 “WHICHWASACELEBRATIONFORHISSUCCESS”所修饰的是整个主句，WHICH所引导的这类特殊的非限定性定语从句对主句所叙述的情况进行某种意义的补充说明，WHICH常可译为“这一点，这件事”。 ［考题1］ YOUCANFINDWHATEVERYOUNEEDATTHESHOPPINGCENTRE， ____ISALWAYSBUSYATTHEWEEKEND.（2006上海春） A.THAT B.WHERE C.WHAT D.WHICH ［答案］D
when 和 where 引导定语从句的用法 定语从句既是英语语法的一个重点，同时又是一个难点。说它是难点，主要难在两点上：一点是如何正确判断什么样的汉语句子要译为英语的带定语从句的复合句；另一点是定语从句的引导词较多(包括关系代词who, that, which, as 和关系副词when, where, why)，而且其用法也较复杂。那么到底什么情况下用when和where来引导定语从句呢？它们又该怎么用呢？下面就举例说明： 一、when：当主句中的先行词(即主句中被后面定语从句修饰的词)是表示时间意义的名词时，它只能作定语从句的时间状语，放在定语从句句首。如果定语从句的引导词是作该定语从句的主语或宾语，则要改用关系代词that或which来引导。例如： The days when we used foreign oil are gone. 我们用洋油的日子一去不复返了。 I'll never forget the day when I was born. (=I'll never forget my birthday.) 我永远不会忘记我出生的日子。 It happened in November when the weather was wet and cold. 这事发生在天气又湿又冷的十一月。 In the years that (which) followed, Marx kept on studying English and using it. 在这之后的几年中，马克思继续学习和使用英语。(that作定语从句"that followed"的主语) The day (that) I always remember in all my life is my birthday. 我一生中最难忘的日子是我的生日。(that作定语从句"that I always remember in all my life"的宾语，that可以省略)
定语从句（1） 概念引入： She is the girl who sings best of all. 她是所有人中唱得最好的。 This is the best film that I have ever seen. 这部电影是我看过的最好的一部。 He had failed in the maths exam, which made his father very angry. 他数学考试没有及格，这使他的父亲很生气。 Give me the book whose cover is green. 把那本儿绿皮儿的书给我。 定语从句是我们初中学过的一项语法，上面这些句子与你初中学的有差别吗？是不是有点不同呢？从这个单元开始，我们将学习定语从句的升级版，但还是从头开始学哟。 语法点拨【高清课堂：定语从句一P1】， 定语从句的定义 Do you know the girl who came here yesterday? 你认识昨天来的那个女孩吗？ The book which he bought the day before yesterday is very good. 他前天买的那本书很棒。 He is the man whom we should learn from. 他就是我们应该学习的人。 Her friend whose home is very far came to see her. 她的那位家很远的朋友来看她了。 其中粗体的部分就是定语从句，划横线的部分叫做先行词，也就是被定语从句修饰的词。 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。 先行词：被定语从句修饰的名词或代词。 关系词：上面例子中的关系代词who, whom, which, that是用来引导定语从句的连接词。这些连接词代替先行词在从句中担任一个成分，如主语、宾语或表语。例如：Those students who study in this school are good at football. （who代替先行词students在从句中充当主语） There is still much homework which we must finish. （which代替先行词homework在从句中充当宾语） 关系代词引导的定语从句 I. who和whom 1. who和whom代表人, 当先行词在从句中作主语时用who引导，作宾语时用whom引导。The girl who is singing is my best friend. 正在唱歌的女孩是我最好的朋友。 （who代替先行词the girl在从句中作主语） His friend who works as a doctor is very interesting. 他那当医生的朋友很有趣。
