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
教学过程 一、复习预习 1、对上节课课后作业中的问题进行查漏补缺； 2、导入： e.g. She is a beautiful girl. She is a beautiful girl who drives me crazy. 二、知识讲解 （一）定语从句定义
1、定语从句：在复合句中，修饰某个名词或代词的句子（做这个名词或代词的定语）叫定语从句，定语从句一般放在被修饰的名词或代词后面。 2、先行词：被修饰的名词或代词叫做定语从句的先行词。 3、关系词：用来引导定语从句的词叫做关系词。 关系代词的种类： 关系代词：that, which, who, whom, whose, as 关系副词：when, where, why 4、定语从句结构：先行词+关系词+定语从句。 a、There she saw a wall of water that was quickly advancing towards her. b、In Japan, someone who sees another person making the gesture will think it means money. c、Visitors can go on exciting rides where they can feel what it is like to do the things they have seen their heroes do in the movie. d、Oprah Winfrey is a black woman whose rise to fame is an inspiring story. （二）定语从句分类 限定性定语从句：从句对先行词进行必要的描述或说明，对先行词起修饰限定作用，从句与先行词紧密相连，缺少它则句义显得不完整，一般不用逗号隔开。非限定性定语从句：对先行词进行补充说明，解释，它与先行词关系松散，用逗号隔开。 1、The man who gave me this book is T om .(限定性) 2、T om,who is reading a book ,is my classmate (非限定性) （三）关系代词 1、who指人，在定语从句中作主语。 e.g. The man who is sitting under the tree is a German . 2、Whom指人，在句中做宾语，可省略，但在做介词的宾语是只能用whom,不能用who。关系代词前有介词时不能省略。 e.g. I know the girl (whom) the teacher is speaking to . I know the girl to whom the teacher is speaking . 3、whose, 作定语，可指人或物 e.g. Everyone heplps the child whose parents are dead. They are the lazy students whose homework wasn’t handed in . 4、that 指人或物，多指物，作主语（不能省略）或宾语（可省略） e.g. He is the finest comrade that has helped us . This is a plant that grows in the north . 5、which ,指物，在句中做主语（不能省略），或宾语（可省略）。 e.g. This is a plant which grows in the north . ☆常用that不用which的情况 1、当先行词是all, everything, anything, nothing, much, little, none, one等不定代词时，只用that。 歌诀助记：不定代词这路货，全用that准没错。 Pay attention to everything that I do.
高中英语定语从句几个难点的教学 定语从句（Attributive Clauses）即从句在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词。定语从句由关系词（关系代词或关系副词）引出。定语从句是高中语法的重要组成部分，也是历年高考考查的重点。虽然学生在初中就已经初步接触了定语从句，但是由于定语从句的关系词有多样性，先行词比较复杂，且从句本身的位置非常灵活的特点，所以学生会遇到很到让他们感到束手无策的定语从句问题。在笔者的教学实践中发现，大多数学生在关系词的确定，as既能引导限定性定语从句也能引导非限定性定语从句，“名词/代词/数词/比较级或最高级+of+关系代词”引导的定语从句及定语从句和其它从句的区别上等方面困惑较大。本文从以上几个方面进行反思。 一：引导定语从句的关系词的确定 正确选择关系词是掌握定语从句的关键。引导定语从句的关系词有关系代词that, which, who, whom, whose, 和as。引导定语从句的关系副词有where, when, 和why。学生的困惑就在于碰到地点，时间，还有原因类的先行词时，就不知道是用关系代词还是关系副词了。例如： Group1：a) Is this the factory you visited last week? b) Is this the factory your father worked ten years ago? Group2：a) The day she spent with us was never to be forgotten. b) The day she played with us was never to be forgotten. 要准确地解决上面的两组问题，只要弄清楚一点，即关系词在定语从句中所充当的句 通过分析上面四个定语从句，我们很快就可以找出正确答案。Group1: a) that/which b) where Group2: a) that/which b) when 二：as既能引导限定性定语从句也能引导非限定性定语从句 学生对非限定性定语从句掌握得最好的是which引导的非限定性定语从句。as虽然在高中课本中和各类考题中都有出现，但教材上的语法归纳却涉及很少，是学生在定语从句学习中的一个盲点。但是as引导的定语从句也不难掌握。

定语从句 一、基本概念：定语： 定语从句： Do you know the man who spoke at the meeting just now That is the house where he lived ten years ago. 引导词：关系词 关系代词有：that, who, whom, whose, which; 在从句中充当： 关系副词有：when, where, why. 在从句充当： 先行词： 定语从句中引关系词的作用： 二、关系词的用法： （一）关系代词的用法： 1． He is the man lives next door.

（二）关系副词的用法： 1． I still remember the time ________I first became a college student. Do you know the date __________Lincoln was born (三) 使用关系副词应注意下列几点： 1．这三个关系副词在意义上都相当于一定的介词+which结构： when = on (in, at, during…) + which; where = in (at, on…) + which; why = for which. 如： I was in Beijing on the day when (=on which) he arrived. The office where (=in which) he works is on the third floor. This is the chief reason why (=for which) we did it. 2．当先行词是表时间的time, day等和表地点的place, house等时，一定要注意分析从句的结构，如果缺少主语或宾语时，关系词应该用which或that, 缺少时间状语或地点状语时，才能用when或where，试比较： I’ll never forget the day _________ my hometown was liberated.

在复合句中充当定语的从句叫定语从句。定语从句的作用相当于形容词，用来修饰主句中的某一名词或代词或整个主句，所以，也称作形容词性从句。被定语从句修饰的词叫先行词，定语从句一般紧跟在它所修饰的先行词之后。在先行词和定语从句之间起连接作用的词叫关系词。关系词有关系代词和关系副词两种。 提示：关系词在定语从句中有三大作用 1. 连接作用——连接先行词和定语从句。 I I . 我把我所有的钱都给了她。（连接先特词和定语从句I ） 2. 替代作用——在定语从句中替代从句所修饰的先行词。 a . 住在隔壁的那个人是个名师。（替代） 3. 成分作用——在定语从句中作主语、宾语、定语或状语。 I . 我喜欢传统的中国画。（在定语从句中作主语） 一、关系代词引导的定语从句 引导定语从句的关系代词主要有, , , , 等。它们分别代替前面的先行词，并在定语从句中作主语、宾语或定语。 A． 指人，在定语从句中作主语。 ? 借钱给你的那人叫什么名字？（定语从句修饰先行词） . 谁笑到最后谁笑得最好。（定语从句修饰先行词） , , . 会议主席坐在我右边，他先发言。（定语从句修饰先行词） B． 指人，在定语从句中做宾语。在口语或非正式文体中，可省略或可用来代替，但在介词后面以及在非限制性定语从句中只能用。 . 有些人我们是喜欢的，有些人则是我们讨厌的。（定语从句分别修饰先行词, ） I . 和我一起工作的人都很友好。（定语从句修饰先行词） . , I , . . , I , . 昨晚我在电话里和卡特先生交谈过，他对我们的计划很感兴趣。（非限制性定语从句中不能用代替） , I , . 两个人来到我的办公室，我以前从未见过他们。（在介词后面不用） C． 人、物皆可，做定语，后面要紧跟被修饰的名词，先行词和后面的名词之间往往是从属关系。 . 有些人，他们的脸你永远难以忘怀。（定语从句修饰先行词） I . 我看见一些树的树叶由于空气污染而发黑。（定语从句修饰行词） D． 1．指物，在定语从句中做主语或宾语。做宾语时常可省略。
定语从句 一、基本概念： 定语： 定语从句： Do you know the man who spoke at the meeting just now That is the house where he lived ten years ago. 引导词：关系词 关系代词有：that, who, whom, whose, which; 在从句中充当： 关系副词有：when, where, why. 在从句充当： 先行词： 定语从句中引关系词的作用： 二、关系词的用法： （一）关系代词的用法： 1． He is the man lives next door. The train has just left is for Shenzhen. 2． The man ________ we have just seen is a famous writer. Where is the book ___________I bought last week （二）关系副词的用法： 1． I still remember the time ________I first became a college student. Do you know the date __________Lincoln was born
(三) 使用关系副词应注意下列几点： 1．这三个关系副词在意义上都相当于一定的介词+which结构： when = on (in, at, during…) + which; where = in (at, on…) + which; why = for which. 如： I was in Beijing on the day when (=on which) he arrived. The office where (=in which) he works is on the third floor. This is the chief reason why (=for which) we did it. 2．当先行词是表时间的time, day等和表地点的place, house等时，一定要注意分析从句的结构，如果缺少主语或宾语时，关系词应该用which或that, 缺少时间状语或地点状语时，才能用when或where，试比较： I’ll never forget the day _________ my hometown was liberated. I’ll never forget the days____________we spent together last summer. His father works in a factory____________radio parts are made. His father works in a factory______________makes radio parts. 三．限制性定语从句与非限制性定语从句 1．限制性定语从句 This is the telegram which he refers to.
