一、定语从句概述
定语可以由形容词、名词、代词、数词、分词、副词、不定式以及介词短语等来担任，也可以由一个句子来担任。在句子中起定语作用的从句称为定语从句。定语从句在句中的作用相当于形容词，故又称为形容词性从句。被定语从句修饰的名词叫先行词，引导定语从句的词叫关系词。
二关系词的用法。
关系词可分为关系代词和关系副词。关系词指代先行词，放在先行词与定语从句之间起连接作用，同时又充当定语从句中的某一种成分（主语、宾语、状语等）。
引导定语从句的关系代词有"at，who，whom，whose，which;关系副词有when，where，why等。关系词在句子中的指代作用及成分如下表
1.关系代词的用法
(1)who, whom的用法
二者都用于指人。who在定语从句中作主语、宾语;whom在定语从句中作宾语。在现代英语里，有时who也可代替whom在从句中作宾语。作宾语的关系代词who，whom可以省略(介词后作宾语的关系代词除外）。She was the one who did most of the talking。大部分时间都是她在说话。（作主语） The boy who I know studies best in his class.我认识的那个男孩在班上学习最好。（作宾语）
I happened to meet the professor (who/whom) I got to know at a party. 我
碰巧遇见了那位在一次聚会上认识的教授。（作宾语，whom可用who 代替)
whom在从句中作介词的宾语，且介词提到whom前面时，不能用who 代替。
Yesterday I came across a few friends with whom I went to the park.昨天我碰见了几个朋友，我和他们一起去了公园。（句中的whom不能用who 代替）
(2)whose的用法
whose可以指人也可以指物，在定语从句中作定语。
Is she a teacher whose hair is very short?她是位头发很短的老师吗？
He is the man whose car was stolen last night. 他就是昨晚被盗车辆的车主。I like the room whose window looks out to the sea.我喜欢那间窗户面向大海的房间。
(3)which的用法
which —般指物，在定语从句中作主语、宾语。作宾语的关系代词which 可以省略(放在介词后时除外）。The train which has just left is for Shenzhen.刚开走的火车是驶往深圳的。（作主语）The story (which) he told was very popular.他讲的那个故事很有名。（作宾语）
(1)that的用法
that可以指人或物，在从句中可作主语、宾语或表语。作宾语或表语时可省略。作介词宾语时，介词不可以提到that之前，若介词提前，指物用which，指人用whom。
E-mail English is a new kind of written English that/which is being used to save time.电子邮件英语是一种可以节约时间的新型书面英语。（作主语"指物)

关系副词在定语从句中充当状语，一般不可省略。
(1)when的用法
when指时间，在从句中作时间状语，它的先行词通常为time, day，morning，night，week ,year 等表M时间的名词。

1. 用that不用which的情况
that和which都可指物，在定语从句中又都可作主语或宾语。通常情况下，二者可互换使用，但有时that和which却不宜互换。
(1)当先行词是不定代词all，little，few，much，something，anything，everything, nothing，none，some 等时
He did everything that he could to help us. 他做了一切能做的事来帮助我们。In this factory I found little that was different from ours.在这家工厂，我们发现很少和我们工厂不同的地方。
(2). 先行词被alll，every，no，some，any，little，much，the only，the very，the right，the last, just 等词修饰时All the things that we can do are to give you some advice.我们能做的就是给你提供一些建议！This is the very book that I want.这正是我想要的那本书。

clothes shop. 我过去住的房子现在变成了一家服装店。The pen with which you are writing is Jeff’s. 你正用来写字的那支笔是杰夫的。

3. 用who不用that的情况
(1)先行词是指人的不定代词时:先行词如果是指人的不定代词或指示代词，如one，

3. 定语从句中的主谓一致
一般来讲,定语从句中的动词在人称和数方面应该与它的先行词保持一致.定语从句前是“one of+可数名词复数”，从句的谓语动词用复数形式; 是“the only one of+可数名词复数”, 定语从句的谓语动词用单数形式。
I am not one who is afraid of difficulty.我是个不怕困难的人。
Anyone who has questions to ask，please come to my office this afternoon. 有问题要问的人，请今天下午到我办公室来。
That is one of the most expensive dictionaries that have come out in recent years.那本词典是近几年来所出版的最贵的词典之一。
He is the only one of those workers who o able to do this job.他是那些工人中唯一能做此项工作的人。
4. 定语从句中的时态:定语从句中的时态一般不受主句影响，主要根据具体的语境和意义而定。

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)
定语从句 一、定语从句 定语从句在复合句中做定语，修饰一个名词或代词，被修饰的名词、词组或代词叫做先行词。定语从句通常出现在先行词之后，由关系词（关系代词和关系副词）引出。 关系代词：who、whom、which、that、whose 关系副词：when、where、why 关系词常有三个作用：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 二、定语从句的引导词 先行词成分 关系代词 who whom which that whose 人 人 物 人/物 人/物 主语、宾语 宾语 主语、宾语 主语、宾语、表语 定语 关系副词when where why 时间 地点 原因 时间状语、表语 地点状语、表语 原因状语、表语 三、用法 1、关系代词引导的定语从句 （1）who, whom, that 代替的先行词是指人的名词或代词 Is he the man who / that wants to see you? 他就是想见你的人吗？ 注：当引导词在从句中作主语时，谓语动词的人称和数的变化取决于先行词。 Is he the man who / that wants to see you? He is the man whom / that I saw yesterday. 他就是我昨天见的那个人。
（2）which, that 代替的先行词是指事物的名词或代词 This is the family which / that is planning to move to the city. 这是正计划要搬进城里的一家。 The book which / that I am reading is written by Tomas Hardy. 我正读的这本书是由托马斯·哈迪写的。 （3）whose用来指人或物（在从句中只能作定语，若指物，可以和of which互换） They rushed over to help the man whose car had broken down. 那人的车坏了，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。 2、关系代词的特殊用法 （1）关系代词指物时, 用that而不用which的情况: 1）先行词为something, anything, nothing, everything以及all, much, little, a lot, none, few 等不定代词时。 e. g. My mother was so proud of all that I did. 辨析：My mother was so proud of what I did. （all that = what） 2）先行词有the last, the very, the only等修饰时。 e. g. This is the very book that I’m looking for. 3）先行词为序数词、形容词最高级(或所修饰)时。 e. g. This is the most exciting film that I’ve ever seen. When people talk about Hangzhou, the first that comes to their mind is the West Lake. 4）先行词既有人又有物时, 只能用that。 e. g. Do you remember the book and its author that appeared on TV last Sunday. 5）There be 后面的定语从句多用that引导, 不用which。 e. g. There’s a seat in the corner that is still free. 6）句子前面出现了who, which 时, 后面的定语从句用that引导。 e. g. They built a factory which made some new products that had never been seen before. 7）关系代词在定语从句作表语时, 常用that, 而不用which、who。 e. g. My home town is not the small village that it was 10 years ago. Tom isn’t the man that he used to be.
定语从句 一学习目标 1.熟练掌握定语从句 二考点解析 ⊙定从的功能—解释说明 This is the factory that/which can produce such machines 这就是能制造这种机器的工厂This is the factory that/which we visited last week 这就是我们上周参观的工厂 ⊙定语从句 定义：一个简单句跟在名词或代词后（先行词）进行修饰限定，就叫做定语从句。这个简单句在主句中充当定语成分。 I bought a cow that looked like a horse. ⊙定语从句怎么考？ 语法 22.I live next door to a couple children often make a lot of noise.（2016高考北京卷） A.whose B.why C.where D.which 完形 Balto put his nose to the ground, 52 to find the smell of other dogs that had traveled on the trail. （2016高考北京卷） 阅读&写作 A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.（2016高考全国卷D篇） Last year, I spent all my time looking for a job where, without dealing with the public , I could work alone, but still have a team to talk to. （2016高考北京卷阅读A篇） ⊙定从原理：把两个句子合为一个，两个句子有相同的部分，此时可以把其中一个句子作为另一个句子的修饰限定部分。
从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]
1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms. The news that we are invited to the conference is very encouraging.
定语从句讲解 1.注意英汉差异：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，如： ①.a beautiful girl ②.a lovely boy 是两个以上的词组、短语或从句则放在被修饰词的后面，如： ③.She is the girl in red. 她就是穿红衣的女孩。 ④.The lady carried a bag full of money. 那位女士背了个装满钱的包。 ⑤.He is the man who you are looking for. 她就是你在找的人。 2.分清主句与从句，看究竟哪个句子缺少成分。 如上面第5： 主句：He is the man 从句：who you are looking for 在从句中，looking for 的宾语是the man.因此选用关系代词who(whom)放置于句首，便是定语从句。3.从句中做宾语的关系代词可以省略， 故第5题可以写成： He is the man you are looking for. 1、功能：相当于形容词，修饰名词或代词，在句中作定语 2、位置：定语从句置于被修饰词之后 Those who are willing to attend the party, sign here please. 3、先行词：被定语从句修饰的词称为先行词 （1）先行词一般是名词和不定代词，如:some-, any-, every-和no与-boy, -thing的合成词；或all、none、any、some、that、those等代词。数词也可以作先行词，人称代词也同样可作先行词。 （2）先行词与关系词是等量关系。必须注意两点： ①先行词在从句中作主语时，从句谓语动词的数由先行词而定。 This is the place which is worth visiting. ②关系词在从句句子中充当了成分，其意思就是先行词的意义，所以在从句中不能重复其意。 There are many places we can visit（them）in China. 4、关系词：引导定语从句的都称关系词 关系代词：who, whom, which, that, whose, as. 关系副词：when, where, why. (that偶尔也作关系副词。) 5、确定关系词的步骤 （1）先找关系词，看先行词指的是什么。 （2）看关系词在从句中所充当的成分。 6、在定语从句中，当先行词指物时，下列情况的关系词宜用that而不用which （1）先行词被①形容词最高级②序数词③数词几种词修饰或被④only、any、few、little、no、all、one of等修饰时。 （2）先行词为all、much、little、none、few、one、something、anything等不定代词时。 （3）先行词中既有人又有物时。 He was looking pleasantly at te children and parcels that filled his bus. （4）先行词在主句中作表语关系词在从句中作表语时。 The village is no longer the one that was 5 years ago. （5）当主句中含有疑问词which时。 Which are the books that you bought for me ?
定语从句专项讲解与练习 定语从句的定义：从句作定语，修饰名词、代词，这样的从句叫定语从句。 定语从句所修饰的词叫先行词。定语从句作定语放在先行词的前面。 如果要表达:我喜欢那个漂亮的女孩。I love the pretty girl. 如果要表达：那个喜欢我的女孩。只能借助于定语从句the girl who loves me. 其中the girl即为定语从句的先行词，而who即为定语从句的关系词。 指人：who、whom 关系代词指物：which、as （作主宾表）指人和物:that,whose 关系词表时间：when 关系副词表地点：where （作状）表原因：why 1、who 指人，who在从句中当主语。 He who has not reached the Great Wall isn’t a true man. 不到长城非好汉。 The teacher ___________spoke at the meeting just now is having a rest in his office. 中文意思：____________________________________________________________________ ?作主语时不能省略，作宾语时可省略。 2、whom 指人，是who的宾格形式，在从句中作宾语，前面没有介词时，可用who/that来代替，也可省略。The girl ___________________ I like isn’t here now. 中文意思：____________________________________________________________________ The doctor with ________________she went to the United States last month is very famous. 中文意思：____________________________________________________________________ The person ___________________ you met yesterday is our Chinese teacher. 中文意思：____________________________________________________________________ 3、whose 指“谁的”，或“某物的”，在从句中作修饰词。 whose和它所修饰的名词在定语从句中可作主语及动词或介词的宾语。 The girl ___________father is a doctor is our classmate.

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
