新概念英语定语从句讲解

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。

The man who / that I saw at the school gate yesterday is my English teacher.

先行词定语从

我在校门口看见的那个人是我的英语老师。

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。

①I am waiting for the boy who /that is wearing a red coat. （关系代词作主语）先行词关系代词我正在等穿着红色外套的那个男孩。

②The dictionary that / which my sister gave me last Sunday is very expensive.

先行词关系代词（关系代词作宾语）

我姐姐上周星期天给我的那本字典很贵。

③The woman whose name is Linda Brown is his mother. （关系代词作定语）

先行词关系代词

那个是他的母亲，名叫琳达?布朗。

④That is the house where my father used to live. （关系代词作状语）

先行词关系副词

那是我父亲曾经居住过的房子。

三、关系代词的用法

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，作宾语时可省略。例如：

①Mary likes music that is quiet and gentle. 玛丽喜欢轻柔的音乐。(that作主语)

②The 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：

①The building which stands near the train station is a supermarket. 位于火车站附近的那座大楼是一家超市。(作主语)

②The film (which) we saw last night was wonderful.

我们昨天晚上看的那部电影很好看。(作宾语)

3. who, whom都用于指人，who用作主语，whom用作宾语。在口语中，有时可用who代替whom，也可省略。例如：

①The girl who often helps me with my English is from England. 经常在英语方面帮助我的那个女孩是英国人。(作主语)

②Who is the teacher (whom) Li Ming is talking to? 正在与李明谈话的老师是谁? (作宾语)

*****小结：that—既可指人，也可指物，作主语，不能省略；作宾语，可以省略。which—指物，作主语，不能省略；作宾语，可以省略。

who—指人，作主语，不能省略；作宾语（常用whom），可以省略。

注：当关系代词在定语从句中作主语时，定语从句的谓语动词形式由先行词定。

注意——

(1) 当定语从句中含有介词，介词放在句末时，who, that, which可省略，但介词在关系代词

前时，只能用“介词+ which/whom”结构。例如：

①This is the house in which we lived last year. 这是我们去年居住的房子。

②Please tell me from whom you borrowed the English novel. 请告诉我你从谁那借的这本英文小说。

(2) 含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。例如：This is the person whom you are looking for. 这就是你要找的那个人。

(3) that 作介词的宾语时，介词不能放它的前面，只能放在从句中动词的后面。例如：The city that she lives in is very far away. 她居住的城市非常远。

***** (4) 关系词只能用that而不用which的情况：

a. 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。

b. 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?

c. 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。

d. 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。

e. 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?

f. 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。

(5) 关系词只能用which，而不用that 的情况：

a. 先行词为that, those时，用which, 而不用that。例如：

What’s that which is under the desk? 在桌子底下的那些东西是什么?

b. 关系代词前有介词时,一般用which,而不用that.例如:

This is the room in which he lives. 这是他居住的房间。

c. 引导非限制性定语从句，用which, 而不用that。例如：

Tom came back, which made us happy. 汤姆回来了，这使我们很高兴。

初中英语定语从句的用法解析

初中英语定语从句的用法解析 【摘要】定语从句是一种形容词的关系从句。它由关系代词或关系副词引导（1）。初中英语中的定语从句仅限于限制性定于从句，但对初中生来说，定语从句既是一个重点，也是一个难点。 【关键词】定语从句先行词关系代词关系副词 一、英语中的定语从句与汉语中的定语位置不同。 在复合句中，修饰某一名词或代词的从句叫做定语从句。英语中的定语从句始终要放在被修饰的词之后，而汉语中的定语则放在被修饰词之前。如： The man who / that I saw at the school gate yesterday is my English teacher. 先行词定语从句 昨天我在校门口看见的那个人是我的英语老师。 二、英语从句中的句型结构比较复杂，有先行词、关系代词或关系副词。被定语从句修饰的词叫先行词，引导定语从句的关联词有关系代词或关系副词。限制性关系分句和它的先行项的所指意义有着不可分割的联系（2）。关系代词或关系副词放在先行词和定语从句之间起纽带作用，关系代词或关系副词在定语从句中要充当一个成分。关系代词在句中可作主语、宾语或定语，关系副词在句中作状语。如： I am waiting for the boy who /that is wearing a red coat. （主语） 先行词关系代词 我正在等穿着红色外套的那个男孩。 The dictionary that / which my sister gave me last Sunday is very expensive.(宾语) 先行词关系代词 我姐姐上周星期天给我的那本字典很贵。 The woman is his mother whose name is Linda Brown. (定语) 先行词关系代词 那个是他的母亲，名叫琳达·布朗。 That is the house where my father used to live.(状语) 先行词关系副词 那是我父亲曾经居住过的房子。 三、初中英语中的定语从句关系代词或关系副词的具体用法。 1. who指人（也可用that），在定语从句中作主语，也可作宾语。如： Yesterday I helped an old man who / that lost his way. （主语） 昨天我帮助了一位迷路的老人。 Mr Wang is the man (who / that / whom )you met in the zoo this morning.(宾语) 王先生就是今天早上你在动物里遇到的那个人。 注意：关系代词who指人,作宾语时，可用whom代替；作宾语时，关系代词可省略。作其它成分，关系代词则不能省略。 2. whose指人，也可指物。在定语从句中作定语。 The boy whose mother is ill is staying at home to look after her today. 其母亲生病的那个男孩今天呆在家里照顾她。 I have a story book whose cover is red. 我有一本封面是红色的故事书。 3. which指物（也可用that），在定语从句中作主语，也可作宾语。如： Football is a game which / that is liked by most boys. （主语） 足球是被大多数男孩喜欢的运动。 I don’t believe the news which / that Tom won the game. (宾语)

高中英语语法定语从句总结全

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

高中英语定语从句讲解及练习 定语从句是高中重点知识，也是高考常考点，大家也不容易掌握，这篇文章主要教你关系代词引导的定语从句 关系副词引导的定语从句判断关系代词与关系副词限制性和非限制性定语从句等内容，有例题讲解定语从句在句中做定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。 关系代词有：who, whom, whose, that, which等。 关系副词有：when, where, why等。 18.1 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作主语时，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，在从句中作主语和宾语。例如： Is he the man who/that wants to see you? 他就是你想见的人吗？（who/that在从句中作主语） He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语） 2）whose 用来指人或物，（只用作定语, 若指物，它还可以同of which互换）。例如： They rushed over to help the man whose car had broken down.那人车坏了，大家都跑过去帮忙。 Please pass me the book whose （of which）cover is green.请递给我那本绿皮的书。 3）which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。例如： A prosperity which / 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） The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。（which / that在句中作宾语） 18.2 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，因此常常和\"介词+ which\"结构交替使用。例如： There are occasions when （on which）one must yield.任何人都有不得不屈服的时候。 Beijing is the place where（in which）I was born.北京是我的出生地。 Is this the reason why （for which）he refused our offer?这就是他拒绝我们帮助他的理由吗？ 2）that代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代when, where, why和\"介+which\"引导的定语从句，在口语中that常被省略。例如： His father died the year （that / when / in which）he was born.他父亲在他出生那年逝世了。 He is unlikely to find the place （that / where / in which）he lived forty years ago. 他不大可能找到他四十年前居住过的地方。 18.3 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. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。 判断改错： （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

新高考下的英语定语从句

定语从句 考纲要求： 掌握定语从句的基本知识；区分定语从句和名词性从句的性质和用法。 在具体的语境中考查非限制性定语从句的引导词以及“介词+关系代词”引导的定语从句；设置语境，考查抽象地点或时间概念的名词作先行词时关系副词的选择，甚至通过增加先行词的隐蔽性来增加试题的难度；考查定语从句的特殊句型，即：特定词汇+of whom/which 引导的定语从句。 复合句中修饰名词和代词的从句叫做定语从句，被修饰的名词或代词叫先行词。引导定语从的连接词有关系代词who, whom, that, which, whose, as 和关系副词when, why, where等。这些关系代词或关系副词有替代先行词，连接主句和从句，并在从句中充当成分三个作用。定语从句有限制性定语从句和非限制性定语从句两类。 限制性从句是句子不可缺少的部分，主句和从句间不用逗号隔开。 非限定性定语从句是对主句先行词的补充说明，去掉不影响主句意思的完整性。一般用逗号把主从句分开。关系代词that不可以引导非限定性定语从句，其他可引导定语从句的连词均可引导非限定性定语从句。

先行词：被定语从句修饰的名词或代词叫做先行词，定语从句必须放在先行词之后。有时先行词是关系代词前的整个句子。 1.当先行词是人： 关系词要用who, whom, that, whose等，其中who/that 在从句中课充当主语或宾语，whom 在从句中只能充当宾语，whose在从句中充当定语,不可省略(of whom 可以代替whose指人，词序是名词+of whom。) This is the man who/that can speak several foreign language.（who/that 在从句中作主语，不可省略） I like the girl (who/whom/that)you referred to yesterday.(who/whom/that 在从句中作宾语，可省略） The government tried to help the old woman whose son (of whom the son/the son of whom）died in the war. [注意：whose与所修饰名词之间无任何冠词，否则要用of whom] 注意： ?若连接词在从句中作介词宾语并且介词在前面，代替人必须用whom，且不可省略There is nobody in the street to whom I can turn for help.(turn to sb for help 求助于某人) ?若介词在后面，则who, whom或that均可引导从句，且可以省略。 There is nobody in the street that /who/whom I can turn to for help. （填一填）The settlement is home to nearly 1000 people, many of ________ left their village homes for a better life in the city. ?在下列情况下多用who或whom,而不用that ①先行词是all, anyone, one, ones, those, people等时 All who can dance well will be invited.（who在从句中作主语） Those who (whom)he knows will be invited.(who/whom在从句中作宾语） ②在被分割的定语从句中 A new teacher will come who will teach us English. ③在there be句型中 There is a girl who wants to see you. ④一个句子中有两个定语从句，其中一个用that引导，为了避免重复，另一个用who. Every student that is from China who likes English will have a chance to get a book. 2.当先行词是物： 连接词要用which，that，whose，which/that在从句中作主语或宾语；whose在从句中作定语，后直接跟名词，无冠词，若有则用of which。（whose是一个表示所属关系的词,在定语从句中做定语,相当于my, his, her, its, their 等修饰人或物。of which可以代替whose指物，词序一般是名词+of which或of which+名词。） The building which/that stands in the center is our school library.（which/that在从句中作主语，不可省略） This is the book (which/that)you want.(which/that 在句中作宾语，可以省略） The building whose window (of which the window)faces south is our school library.(作定语）（填一填）Look out! Don't get close to the house ________ roof is under repair. 注意： ?如果关系代词在句中作介词宾语并且介词在前面，必须用which，且不可省略。 The house in which I live is near yours. The house (that/which )I live in is near yours.

高三英语定语从句翻译技巧

定语从句翻译技巧 英语和汉语分属两种不同的语系，其差别很大，翻译起来有诸多困难，英语定语从句的汉译便是困难之一。由于定语从句在英语中应用十分广泛，因此，我们必须想办法、找方法、寻规律，从而很好地解决它。 一、限制性定语从句 限制性定语从句对所修饰的先行项起限制作用，在意义上与先行项密切不可分。 如被省去，主句的意思就含糊不清，甚至变得毫无意义。关系词和先行项之间一般不用逗号分隔。 （一）定语词组 ①I have but one lamp by which my feed are guided.我只有一盏指路明灯。 ②It was so with the vast railroad yards with the crowded array of vessels she saw in the river.火车站广大的场地，河里鳞次梯比的船只，她也同样不能理解。 ③Before following her in her round of seeking，let us look at the sphare in which her future was to lie.我们暂且把她找寻工作的事搁下来不谈，先看一看她的前途所寄托的这个世界。 ④…and the thread which bound her so lightly to girlhood and home were irretrievably broken……而那些把她和少女时代以及故乡轻轻系住的柔丝，不得不就此断绝了。 翻译这类从句，常常是将关系词省去，在句未加“的”字，放在被修饰项之前。当然，也可视其情况不用“的”字，如①和②。这种译法用得普遍，尤其适用于译简短的定语从句。 （二）并列从句 1）省略英语的先行项 ①The lungs are subjecd to several diseases which are treatable by surgery.肺易受几种疾病的侵袭，但均可经手术治疗。 ②A little way on she saw a great door which，for some reason，attracted her attention.又走了一些路，她看见一个大门，不知怎的，引起了她的注意。 ③As a result， a hum of gossip was set going which moved about the house in that secret manner common to gossip.结果就造成一阵闲话，暗中在公寓里流传，闲话一般都是如此的。
