一定语：修饰名词或代词的词、短语或从句称为定语。汉语中常用‘……的’表示。定语主要由形容词担任。此外名词、代词、数词、副词、介词短语以及动词不定式（短语）、分词也可以做定语。
a beautiful city; a bag full of money.注意：汉语的定语无论多长都放在被修饰词的前面，而英语中的定语则不然，是一个词时，放在被修饰词的前面，若是两个以上的词组、短语或从句则放在被修饰词的后面，
thirty women teachers ; his father; the girl in red. the boy from America
Our monitor is always the first student to enter the classroom.
falling leaves; fallen leaves; the boy playing basketball; the book bought by my mother; a reading room; a swimming pool
He is the man who you are looking for.
二：定义及相关术语
1．定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先行词之后。
2．先行词：被定语从句修饰的名词或代词叫先行词。
3．关系词：引导定语从句的词叫关系词。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when, where, why.
1. I have an apple. An apple is red.
I have an apple that/which is red. ↑↑
先行词关系代词
2.I like some friends. Some friends like sports.
I like friends who like sports.
↑↑
先行词关系代词
3.I like music. The music is quiet.

先行词关系代词
关系词通常有下列三个作用：A、引导定语从句，连接主从句；B、代替先行词；C、在定语从句中担当一个成分。
（二）关系代词引导的定语从句
1．who 指人，在定语从句中作主语。
The boys who are playing football are from Class One. Those who want to go to the museum must be at the school gate at 7 tomorrow morning. Yesterday I helped an old man who had lost his way. That is the teacher who teaches us physics. 2．whom 指人，在定语从句中做宾语，常可省略。

注意：关系代词whom 在口语或非正式文体中常可用who 来代替，也可省略。

3．Which 指物，在定语从句中做主语或宾语，做宾语时常可省略。
Football is a game which is liked by most boys. He likes to read books which are written by foreign writers. The house which is by the lake looks nice. This is the pen ( which ) he bought yesterday.

Do you like the book the cover of which is yellow?
（一）限制性定语从句中只能用that 引导定语从句的情况
1．当先行词是everything, anything, nothing (something 除外), all, none, few, little, some等不定代词时，或当先行词受every, any, all, some, no, little, few, much等不定代词修饰时。如：Have you taken down everything that Mr. Li said?
There seems to be nothing that is impossible to him in the world.
All that can be done has been done. 。
There is little that I can do for you.
He stayed in the library and looked up any information that they needed.
注意：当先行词指人时，偶尔也可用关系代词who，如：

2．当先行词被序数词修饰时。如：

4．当先行词被the very, the only修饰时。如：

6．当先行词为人与物时。如：

（三）关系副词引导的定语从句
1．when 指时间，在定语从句中作时间状语。当先行词是表时间的名词，比如time, day, week, month, year等；且定语从句中缺时间状语时用when. 若先行词是表时间的名词，定语从句
中缺主语或宾语时，用that/which引导。
I still remember the day when I first came to this school.
The time when we got together finally arrived.
Do you remember the years when he lived in the countryside with his grandpare？Do you remember the days（that/which）we spent together last year?

Please tell me the reason why you missed the plane.
I don’t know the reason why he looks unhappy today.
I didn’t believe the reason (that/which) he explained to me
注意：关系副词引导的定语从句经常可以用“介词+关系代词”引导的定语从句来表示。如：From the years when / in which he was going to primary school in the country he had known what he wanted to be when he grew up. Great changes are taking place in the city where / in which they live. The reason why / for which he refused the invitation is quite clear.
（四）“介词+关系代词which/whom”引导的定语从句
关系代词在定语从句中作介词宾语时，从句常常由“介词+关系代词”引出。
The school (which / that) he once studied in is very famous.
The school in which he once studied is very famous.
Tomorrow I’ll bring here the magazine (which / th at) you asked for.

This is the watch (which / that) I am looking for. (正)
This is the watch for which I am looking . (误)
The babies (whom / who / that) the nurse is looking after are very healthy. (正)
The babies after whom the nurse is looking are very healthy. （误）
２．若介词放在关系代词前，关系代词指人时只可用whom，不可用who, that；关系代词指

A．that; whose B．how; who C．what; who D．what; whose 【答案】D 【解析】 that引导宾语从句一般不充当句子成分，只起连接作用；how引导宾语从句，一般做方式状语；what引导宾语从句，做从句的逻辑主语或者宾语。句意：莉莉不知道她和她的朋友们能做什么来帮助这个小男孩，他的父母离开家乡去挣钱了。结合语境可知前文是宾语从句，what，什么，充当宾语从句谓语动词do的逻辑宾语。下文为定语从句，the little 宾语boy和parents是逻辑上的所有关系，故引导词用whose，选D。 考点：英语从句 2．Kids，I hope you’ll remember the good old days____we spent together in junior high though it’s time to say goodbye. A．who B．what C．which 【答案】C 【解析】 【详解】 句意：孩子们，虽然到了说再见的时候了，我希望你们将记住那些我们一起在初中度过的美好的旧时光。who关系代词，引导定语从句，先行词指人，在从句中作主语或宾语；what什么，不能引导定语从句；which关系代词，引导定语从句，先行词指物，在从句中作主语或宾语。根据句子结构可知，这里考查定语从句，先行词是the good old days，从句中spent后缺少宾语，应用关系代词which引导，故应选C。 3．Do you know the man saved three pupils in the accident?

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

定语从句 思维导图 易考易错点总结 定语从句的用法较为复杂，高考除了单独考查定语从句外，还常常结合句式结构、时态等来综合考查。纵观近年各地高考试题，不难发现其考点主要包括： 1．考查如何正确选择关系词 解题思路：找出从句，确定被修饰词，即先行词→将先行词代入定语从句，判断先行词在定语从句中充当什么成分:若作主语、宾语、表语、定语，则选择关系代词；若作状语则选关系副词。 2．考查whose的用法 whose可以指代人或物，在定语从句中作定语，后跟名词。指物时，whose＋名词＝名词＋of which＝of which＋名词。如：The classroom whose door/the door of which/of which the door is broken is on the second floor. 3．考查as/which引导的非限制性定语从句 尤其要重视which，as引导的非限制性定语从句和that，what引导的主语从句的区别。4．考查定语从句中的主谓一致现象。 如：I, who am your close friend, will try my best to help you whenever you are in trouble. 5．考查“介词＋关系代词”引导的定语从句 “介词＋关系代词”引导的定语从句，关系代词指人时用whom，指物时用which，不能用that。关系代词作定语时也可用whose。 如：The teacher in front of whose house stands a tall tree is very patient with his students. 同时还要注意包含复杂介词或代词短语的定语从句与并列句的区别。 如：(1)He loves his parents deeply, both of whom are very kind to him.(定语从句) (2)He loves his parents deeply and both of them are very kind to him.(并列句)

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
