英语中定语从句的基本用法(一) 摘要]本文通过实例浅析了英语中定语从句的基本 用法,如有不当之处,望大家批评指正。 关键词]定语从句用法宾语主语 英语,作为一门学科,每天有很多人在其中徜徉,可是也有 很多人虽为它倾注了很多精力却依然觉得举首无措?的确,在 英语中有很多的学问,需要我们去了解和掌握,下面就其中的某 个方面——定语从句,通过实例,分析一下它的基本用法,和大 家一起学习。 在句子中用作定语的从句称为定语从句。定语从句通常位 于它所修饰的名词或代词之后,这种名词或代词称为先行词。引导定语从句的关联词为关系代词和关系副词。关系代词在定语 从句中可以用作主语、宾语、表语、介词宾语和定语等等;关系副词在定语从句中只用作状语。 I.由关系代词who,whom,whose,which,that引导的定 语从句。 i.who代替人,在从句中作主语。 e.g.Amanwhodoesn’ttrytolearnfromotherscannot hopetoachievemuch. 一个不向别人学习的人是不能指望有多大成就的。 ii.whom代替人,在从句中作宾语,通常可以省略。 e.g.Theengineerwhomwemetyesterdayhaveworked outanewautomaticdevice. 我们昨天碰到的工程师研制出了一种新型的自动化装置。 iii.whose代替人或物,在从句中作定语。 e.g.MadamCurieisagreatscientistwhosenameis knownallovertheworld. 居里夫人是一位世界闻名的伟大科学家。Theyliveinthehousewhosedoorandwindowsareall broken. 他们住在一间门窗都已破败不堪的房子里。 iv.which代替物,在从句中作主语、宾语或介词宾语。作宾 语时,通常可以省略。 e.g.Adirectcurrentisacurrentwhichflowsinone directiononly. 直流电是沿着一个方向流动的电流。Themusictowhichwelistenedlastnightwaswrittenby myfather. 我们昨晚欣赏的音乐是由我父亲写的。 v.that代替人或物。在从句中作主语或宾语,但不能作介 词宾语。作宾语是通常可以省略。 e.g.HeistheonlyoneamongusthatknowsEnglish. 他是我们中间唯一懂英语的人。ThecarthatalmostcrashedintomebelongedtoBrown.
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。如： Do you know the man who spoke at the meeting just now? That is the house where he 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; 关系副词有：when, where, why. 二、关系词的用法： （一）关系代词的用法： 1．作主语用who, which和that, 如： He is the man who/that lives next door. The train which/that has just left is for Shenzhen. 2．作宾语用whom, who, which, that, 如： The man (whom/who/that) we have just seen is a famous writer. Where is the book (which/that) I bought last week? 注：在非正式文体中，用于指人的关系代词who whom, that 通常可以省略，但在正式文体中通常用whom, 不可省略；用于指物的关系代词which和that 在非正式文体中也通常省略，但在正式文体中一般不省略。 3．作定语用whose, 如： (a) He is the man whose car was stolen last week. (b) It was a meeting whose importance I did not realize at that time. 注：“whose +名词中心词”这一结构在定语从句中既能作主语（如上a句），又能作宾语（如上b句）。whose 的先行词常用来指人，但有时也可以用来指具体事物或抽象概念，这时可以与of which 结构互换，词序是：“名词+of which”，如： They came to a house whose back wall had broken down.. (= the back wall of which) He’s written a book the name of which I’ve completely forgotten. (= whose name) 4．作表语只用that ，它既可以指人，也可以指物，但时常省略。如： He is no longer the man that he used to be. This is no longer the dirty place (that) it used to be. （二）关系副词的用法： 1．when 指时间，在从句中作时间状语，它的先行词通常有：time, day, morning, night, week, year 等。如： I still remember the time when I first became a college student. Do you know the date when Lincoln was born? 注：when时常可以省略，特别是在某些句型和某些时间状语中。如： Each time he came, he did his best to help us. But help never stopped coming from the day she fell ill. 2．where指地点，在从句中作地点状语。它的先行词通常有：place, spot, street, house, room,
“介词+关系词”的用法 1、关系代词在从句中作介词的宾语时，介词常可以提前，但介词提前时，关系代词只能用which 或whom。 如：The school (that/which) he once studied in is very famous. →The school in which he once studied is very famous. Tomorrow I will bring here a magazine (that/which) you asked for. →Tomorrow I will bring here a magazine for which you asked. We'll go to hear the famous singer (whom/that/who) we have often talked about. →We'll go to hear the famous singer about whom we have often talked. 2、关系副词when, where, why 和介词+which之间的关系。 关系副词when, where, why可以用适当的介词+which来替代。介词的位置非常灵活，有时放在关系代词之前，有时放在动词之后。如：when=in/on/at…+which, where=in/on/at…+which, why=for+which ） 如：I won’t forget the date when( on which) I was born. This is the room where (in which) I lived. = This is the room which I lived in.
定语从句中关系副词的用法 关系副词，顾名思义，是联系先行词和定语从句的词，属于副词。定语从句中的关系副词有三个：when, where和why，它们在定语从句中分别作时间、地点和原因状语。其句法结构如下： 表时间的名词+ when + 定语从句 when指时间，在定语从句中作时间状语。 例句：I still remember the day when I first came to Beijing. I’ll never forget the day when I joined t he army. 表地点的名词+ where + 定语从句 where指地点，在定语从句中作地点状语。 例句：The factory where his father works is in the west of the city. This is the house where I lived two years ago. 表原因的名词reason + why + 定语从句(why只用于reason之后的限制性定语从句中,在定语从句中作原因状语。) 例句：That is the reason why I did the job.(在现代英语中why可以省略) 上句也可以这样表示： That is the reason I did the job. 又如：This was the reason (why )we raised the temperature. 关系副词在定语从句中的用法看似简单，以下注意点不可忽视： 1）“when”、“where”和“why”的运用取就于表时间的名词、表地点的名词和表原因的名词reason在定语从句中所作的成分，比较下面的几组句子： *I will never forget the day when I first met you on the seashore. *I will never forget the days which/that we spent together in Xueyao Middle School. **This is the hospital where my mother works. **This is the hospital which/that we visited the day before yesterday. ***The reason why he did not go to school is that he was ill. ***This is the reason which/that he gave his boss in the office . 2) “when”、“where”和“why”都可以替换成“介词+ which”，介词的选用取就于先行词和定语从句中的动词。例如： Do you still remember the day on which we first met in Nantong?(on which= when) This is the room in which we lived last year.(in which=where) Do you know the reason for which he refused to go to Mary’s birthday party. (for which=why) 有时定语从句中介词短语和动词有意义紧密的修饰关系，尤其在非限制性定语从句中，常使用“介词+ which”结构，而不使用关系副词。例如： My mother works in a factory, in front of which there is a small river. At night the soldiers got to a small hill, at the foot of which stood a farmhou se. 3) 关系副词“when”、“where”既可引导限制性定语从句，也可引导非限制性定语从句。
定语从句的基本用法 先请认真阅读下列各句，下列各句中的黑体部分均为该句所包含的定语从句： 1.This is the teacher who played basketball with us yesterday. 2.Tom is the boy whom they are looking for. 3.The house , which they built last year looks very new. 4.Physics is the most interesting subject that we learnt in the middle school. 从以上各句中我们可以看出定语从句是用来修饰它前面的名词或代词的，它起着修饰或限定作用。当然定语从句也可以用来修饰一个句子，在此我们不作讨论。定语从句分为限制性定语从句和非限制性定语从句。限制性定语从句所修饰的词是一个、一些或一类特定的人或事物，一般不能省略，拿掉后剩下的部分则没有意义，或者表述不清。非限制性定语从句则不然，它只对所修饰的词作进一步的说明，拿掉以后剩下的部分仍然可以成立，常常用逗号将其隔开。例如： This is the place where the Chinese Communist Party was founded. 此句中的定语从句是限制性定语从句。如果拿掉则This is the place.一句没有意义。 This message was left by Xiao Wang, who telephoned you just now. 此句中的定语从句是非限制性定语从句。如果拿掉则This message was left by Xiao Wang,一句仍有意义。 被定语从句修饰的词叫做先行词，引导定语从句的词称为关系代词或关系副词。常见的关系代词和关系副词有who, whom,that,whose,which,where,when,why等。现在我们侧重讨论如何使用这些关系代词和关系副词。如果关系代词在从句中作主语时一般不能省略，而作宾语时一般可以省略。 一，关系代词who, whom的用法。 1.who可以代替人（即它的先行词必须表示人），在从句中可以担任主语。也可以在 从句中担任宾语，但是它的前面不能带介词，如果带介词则必须使用宾格whom。 whom在从句中只能担任宾语。例如： a)This is the teacher who often tells us interesting stories in class. b)Mary is the girl who/whom Tom wants to marry. c)Mrs White is a teacher whom every student likes. d)She is the girl with whom I will go to Shanghai tomorrow. 2.在定语从句中当先行词表示人时who和that是通用的。例如： a)Miss Green is the new teacher who/that teaches us spoken English. b)John’s father is an engineer who/that came to see him last Wednesday. 但在下列情况下则宜用who 而不用that。
如何正确选用定语从句关系词 关系词的选用让许多学生摸不找头脑，下面我将介绍我的经验。我把关系词的选用分为两个步骤： 第一步、看定语从句中缺少什么成分以确定是选用关系代词还是关系副词。如果定语从句中缺少主语、宾语、定语或表语时，则这个关系词应是关系代词；如果定语从句中缺少时间状语、地点状语或原因状语，那么我们应该选用关系副词。如： This is the book ____ I want. 此句定语从句是I want，经分析，want 是个及物动词，须带宾语，也就是说，定语从句中缺少宾语，由此我们可知空上所填应是关系代词。这就是第一步，确定关系代词还是关系副词。 第二步、看先行词。要弄明白先行词是指人还是指物以及是否受到序数词、最高级等词的修饰以进一步圈定先行词。如在上面例句中，先行词是the book, 是指物且无其他的修饰词，由此我们可以判断关系代词可用which 或that。 通过以上这两个步骤我们就可以确定关系词，但有一点要注意，这两个步骤的顺序不可以弄错，一旦弄错很容易陷入误区。如：This is the reason ____he explained to us. 如果学生先看先行词很容易选用why,而实际上从句中缺少宾语应选用关系代词，这一点就可以排除关系副词why。比较下面两个句子：
○1. Do you still remember the chicken farm ____ we visited three months ago? ○2. Do you still remember the chicken farm ____ we stayed three months ago? 这两个句子看似无差异，但答案不一样。我们按照以上所说步骤顺序来进行分析：在例1 中，定语从句的谓语visited, 是及物动词，其后应接宾语，换句话说，定语从句中缺少宾语应选用关系代词，然后看先行词，the chicken farm 指物且无序数词、最高级等特殊修饰词修饰，所以关系代词应是that 或which；而例2 中，定语从句的谓语是不及物动词stayed，不能接宾语，也就是从句中缺少状语，且先行词是表示地点的名词，所以它的答案是关系副词where。如果我们先看先行词来进行选择，很可能会走进误区。 总而言之，我们同学需要在以后的学习中逐步掌握它的用法，细细体会它的精髓。
定语从句之关系词的选择 一、复习： 1.定语从句的定义:在复合句中，修饰某一名词或代词的从句叫做定语从句。 2.先行词：被修饰的名词或者代词叫做先行词。 3.关系词：引导定语从句的词叫做关系词。 4.关系词：关系代词：which,that,who,whom,whose 关系副词：when,where,why Eg. This is the book___________my father bought for me.（物，宾语） This is a book________has 199 pages.(物，主语) He is the man__________bought a book for me.（人，主语） The boy_________his father bought a book for is Bob.（人，宾语） The boy_________father bought a book for him is Bob.（人，定语） The book________color is red is Bob’s.(物，定语) The visited the town________I lived.(地点状语) They visited the town________I liked.(物，宾语) I will never forget the day_______Obama met Bao Zheng.(时间状语) I will never forget the time________I spent on campus.(物，宾语) That was the reason_______he gave me yesterday.(物，直接宾语) That was the reason________I began to learn photoshop.(原因状语) 关系代词和关系副词用法总结 关系词先行词关系词在定语从句中的成分which 物主语，宾语（可省略） that 人，物主语，宾语（可省略） who 人主语 whom 人宾语（可省略） whose 人，物定语 when 时间状语 where 地点状语 why 原因状语 二、关系词选择两步骤。 1.看先行词是人还是物。 2.看先行词在从句中所处的地位：主语，宾语，定语——关系代词；状语-----关系副词
A good student A developing country A developed country A 5-star friend A man named Chuck A language widely used 定语从句：修饰某一名词或代词的主谓结构(完整的基本句子结构-----五种句型)。 ↓↓ （主句之中）先行词关系词+其它成分 ↓ 在定语从句中必须担当一个成分。 ↓ 定语从句中缺啥就补啥 定语从句(The Attributive Clause) ( (二)关系代词的作用 1. 关系代词：用来连接定语从句，并在从句中代表先行词的代词。 先行词是物：which that 先行词是人：who that ※由who, whom, whose引导的定语从句。这类定语从句中who用作主语，whom作宾语，whose作定语。 e.g. This is the man who helped me. The doctor (whom) you are looking for is in the room. Do you know the man whose name is Wang Yu? ※在定语从句中，若先行词指人，其关系代词可用who, whom, 也可用that。 e.g. The girl who/that is speaking at the meeting is our monitor. The boy (who/whom/that) you saw just now is my brother. 3. 关系代词的具体用法及作用 1).who指人，在从句中做主语。 如：The boys who are playing football are from Class One. 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。 如：Mr. Liu is the person (whom) you talked about on the bus. 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。 如：The man who/whom you met just now is my friend. 3). which指物，在定语从句中做主语或宾语，做宾语时可省略
This is a date that we are all proud of. This is a place ( where) my father has worked. This is a place ( which) my father has lived in for 12years. This is a place (which ) my father has visited several times.
1. This is the ring (on which) she spent 1000 dollars. 2. I can’t remember the age (at which)he won the prize. 3. be clear about the job for which you are applying.
4.This is the house (about which) I wrote to you. 2.There are two doors, one of which leads to the living room. This is the book /which that I bought yesterday. This is the book ( whose )cover is
colorful. 1. The news (that)was reported in the article is incorrect. 2. The news (that)he was resigning is incorrect.

定语从句关系词选择方法 彭玉翠 选题背景： 定语从句为高中教学中的一个重点，也是学生在语法填空或改错题中容易遇到的一个难点。在老师讲解完定从后，学生对关系词的选择似懂非懂，特别是中下等程度的学生。为此，今天特意挑选定语从句中关系词的选择方法为我上课的主要内容，希望有助于学生选择定从中正确的关系词。 教学目标 1. Knowledge aim: review the attributive clause 2.2. Ability aim:To develop the skills to choose correct relative words in the attributive clause 3.3. Emotional aim: let students realize the importance of relative words in the attributive clause 教学重难点 (1) Teaching important point 4.Help Ss to understand realize the importance of relative words in the attributive clause (2) Teaching difficult point 5.How to teach Ss’ to choose correct relative words in the attributive clause 教学过程： Step1:Revision :定语从句是在复合句中起定语作用，修饰某一名词或代词的从句。被定语从句修饰的词叫________。引导定语从句的关系词有关系代词（_____ _____ _________ ______ _____等）
如何选择定语从句的引导词 *限制性定语从句 限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。 who,whom,whose用于指人，whose有时也可指物，相当于of which；which用于指物；that 既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。 *非限制性定语从句 非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。 一、定语从句的引导词有关系代词who，whom，whose，which，that，as；关系副词when，where，why。定语从句中引导词的选用主要看先行词在定语从句中作什么成分或者是定语从句中缺什么成分。 1．定语从句中缺主语，修饰人时用who ／that，修饰物时用which ／that引导。如： Is this the factory which ／that makes TV sets？ The man who ／that visited our school is from Australia． 2．从句中缺宾语，修饰人时用who ／whom ／that或省略引导词；修饰物时用which ／that或省略引导词。如： Gone are the days which ／that we spent together in the village． He is the man who ／whom ／that I think to be worthy of our praise． 3．从句中缺时间状语，用when或介词＋which引导。如： The day finally came when ／on which I was given a job． We'll put off the outing until next week，when we won't be so busy． 4．从句中缺地点状语，用where或介词＋which引导。如： Please put the letter on the desk where ／on which he can easily find it． 5．从句中缺原因状语或先行词是reason时，引导词用why ／for which ／that。如：This is the reason why ／for which ／that he didn't come to the meeting．
如何辨别定语从句的关系词 塘桥中学包小波 同学们，你们知道以下这些谚语吗？ It’s the first step that costs. 万事开头难。 Not all that glitters is gold. 闪光的未必都是金子。 He who would climb that ladder must begin at the bottom. 千里之行，始于足下。 A good book is a best friend who never turns back upon us. 好书如挚友，情谊永不变。 在这些句子中，你发现什么共同点了吗？对了，这些句子都运用了定语从句。定语从句在复合句中的作用相当于形容词，在句中作定语，修饰前面的名词或代词。斜体加粗的单词都被称为关系词，也叫引导词。被定语从句修饰的词称为先行词，就是上述谚语中有下划线的单词，定语从句一般放在先行词的后面。 要想掌握定语从句，就必须了解引导定语从句的关系词。关系词分为关系代词和关系副词。关系代词有who，whom，whose，that，which和as，关系副词有when，where和why，他们在先行词和定语从句之间起联系作用，同时在意义上代表先行词，并在定语从句中担任某个成分。 我们要辨别定语从句中不同的关系词，必须掌握以下的方法。 一、关系代词的用法 1．普通代词与关系代词的区别 例如： I have a brother. He likes playing the piano.（合并为一句） I have a brother who/that likes playing the piano. 简单句中的普通代词he起了指代前一句中brother的作用，并且是本句的主语，两个句子都是独立的。而两句合并后，句中的关系代词who/that除了代替先行词brother之外，它还在定语从句中担任了一定的成分，同时连接先行词与它引导的定语从句。 2．who指人,做主语。 例如：The person who is in blue will go to the concert with me tomorrow. 本句中的who充当从句中的主语, 划线部分是从句。当who作为定语从句的关系代词在句中充当主语或宾语时，都可以用that来替代。 3．who/whom指人,做宾语。 例如：The man who/whom I look after is my father. 在例句中，who/whom做从句中介词with的宾语，这个句子也可以写成The man with whom I talked is our teacher. 如果从句中介词提前，那么就不能用who或that，只能用whom引导从句了。这
定语从句（三） 非限制性定语从句 非限制性定语从句起补充附带说明的作用，缺少它也不会影响全句的理解，译为汉语时常常不译作定语，而根据句意翻译为相应的其他形式的从句。它与主语的关系不像限定性定语从句的关系那样密切。在非限定性定语从句的前面往往有逗号隔开，如果把非限定性定语从句放在句子中间，其前后都要用逗号与主句隔开。 ②引导非限定性定语从句的关系副词主要有when, where。不可用why。 2. 运用非限定性定语从句的情况： （1）关系代词指代整个主句内容 e.g. Our new house has a lovely garden, which makes us very happy. （2）当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的。例如： Charles Smith, who was my former teacher, retired last year. （3）当出现some, many, few, a few, little, much, most, two of which, whom等结构时 e.g. You’ve made many mistakes, most of which were due to your carelessness,
非限制性定语从句主要在以下方面不同于限制性定语从句： ⑴非限制性定语从句和主句的关系不十分密切，它不是对先行词进行修饰或确定，只是对先行词作些附加的说明。专有名词通常被非限制性定语从句所修饰。例如：地名，人名，国家名等。 ⑵非限制性定语从句不是先行词必不可少的修饰语，因此如果去掉从句，主句的意思仍然清楚。 ⑶从句和主句之间往往用逗号分开，翻译时复合句通常译成两句话。 ⑷与限制性定语从句一样，非限制性定语从句也可用关系代词who, which, whom, whose, as 和关系副词when, where, why 引导。that不引导非限制性定语从句。 例如： ①We will fly to Xi’an first, where we plan to stay for a couple of days. 我们将先飞往西安，在那里我们打算停留两天。 ②My wife, who is a doctor, is working abroad this year. 我的妻子是位医生，她今年在国外工作。 ③As is known to all, ice is water in its solid state. 众所周知，冰是水的固态。 ㈢非限制性定语从句中值得注意的几个问题 ⑴在which引导的非限制性定语从句，先行词可以是一个名词或代词，也可以是句子的一部分，甚至整个句子。 例如： ①My new car, which I paid several thousand dollars for, isn’t running well. 先行词是car ②He said that he had never seen her before, which was not true. 先行词是he had never seen her before ⑵which和as引导的非限制性定语从句比较 which和as都可引导非限制性定语从句，并且先行词都可以是一句句子，但which通常指代上文提到的情况，而as则可以指代上文或下文。as 在这类句子中经常有“正如”的意思。另外，as还经常与such, the same 等连用。（见第一讲中as 引导的定语从句） 例如： ①He has to work on Sundays, which he doesn’t like. ②As we expected, he gave a wonderful performance. ③Mike is late, as is often the case. ④I never heard such stories as he told. ⑤She knew he felt just the same as she did. ⑶在从句中作宾语的关系代词which, who, whom一般不省略。 例如： ①Jeanne was her old friend, from whom she borrowed a necklace. ②He built a telescope, through which he could study the skies. 4. as与which的区别：
定语从句关系词选择三部曲
1）、首划先行词，确定人或物 2）、分析定语从句部分是否缺成分（主谓宾定状补） 缺成分------关系代词 不缺成分-----关系副词 3）、根据分析，选择恰当连词 针对习题库 1.The English-Chinese dictionary ____ my father bought for me many years ago is still of great value.
