完整版)高中英语定语从句讲解及练习定语从句是高中英语的重点知识，也是高考常考点。
本文将主要讲解关系代词引导的定语从句，并解释关系副词引导的定语从句，包括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，并提供例题讲解。
定语从句在句中作定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。
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。
它们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。
当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。
例如，当先行词是人时，可以使用who或whom作为关系代词。
如：Is he the man who/that wants to see you?（他就是你想见的人吗？）关系代词在从句中作主语。
而当先行词是物时，可以使用which或that作为关系代词。
如：The package（which / that）you are carrying is about to come unwrapped.（你拿的包快散了。
）关系代词在从句中作宾语。
除了who。
whom。
whose。
that。
which，还有关系副词when。
where。
why等。
关系副词引导的定语从句也可以修饰一个名词或代词。
例如：I still remember the day when we met.（我仍然记得我们相遇的那一天。
）关系副词when在从句中作时间状语，修饰先行词day。
总之，掌握定语从句的用法和关系词的选择是英语研究的重要内容。
通过不断的练和实践，相信大家可以掌握这一技能。
关系副词可以代替时间、地点或理由的名词，在从句中作状语。
例如，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。
比如，有时候我们必须屈服，这是任何人都会遇到的情况（There are ns when [on which] one must yield）。
非限制性定语从句语境呈现1观察下列句子，注意划线部分的用法。
1)This note was left by Mr.Li,who was here a moment ago.2)This novel,which I have read three times,is very touching.3)The bus ran into a crowd of people,some of whom were sent to hospital.4China has hundreds of islands,the largest of which is Taiwan.5)She was kinder to her youngest son than to the others,which,of course,made the others envy him.6)All of my books are on the desk,where I always keep them.7)My brother,whose skin is a little black,has a slim figure.8)They decided to put off the meeting until next Saturday,when they wouldn’t be so busy.规律精点1 所谓非限制性定语从句，顾名思义，对主句所描述的人或物起的作用，去掉后主句意思仍然完整；它与句子之间常用逗号隔开，其引导词有who,whom,whose,which,when,where,as。
that和why 不能引导分限制性定语从句。
有时用不定代词、数词或形容词最高级+of+whom/which指代先行词或先行词的一部分。
语境呈现2观察下列句子，注意划线部分的用法。
1)As is known to us,the sky is blue.The sky is blue,which is known to us.2)The big tree was cut down yesterday,as is reported in today’s newspaper.The big tree was cut down yesterday,which is about three hundred years old.规律精点2 关系代词as引导非限制性定语从句，其与which的区别在于：1)as引导的非限制性定语从句可置于句首、居中或句尾；which引导的非限制性定语从句只能置于。

定语从句定语：定语用来限定、修饰名词或代词的,是对名词或代词起修饰、限定作用的词、短语或句子,汉语中常用‘……的’表示;例如 a clever boy the boiling water fallen leaves•The boy in the classroom needs a pen.•The man standing there is my teacher.定语从句：一个句子充当定语The boy who is reading needs the pen.单词作定语时通常放在它所修饰的词之前,作前置定语;短语和从句作定语时则放在所修饰的词之后,作后置定语;Ⅰ. 概念：1 定语从句：在主从复合句中用作定语的从句叫定语从句;定语从句一般紧接在先行词后面;2 先行词：被定语从句修饰的成份;先行词可以为一个词,短语,或整个主句;3 关系词：引导定语从句的词,并代替先行词在从句中担任一定的成分;分为关系代词和关系副词;4 定语从句基本构成：先行词+关系词+从句A 关系词的作用：1 引导定语从句,连接主句和从句,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1.The student who answered the question was John.2. I know the reason why he was so angry.3. The boy whom you are talking to is my brother.4. I’d like a room whose window looks out over the sea.B简单句变定语从句例1：The girl is Mary. The girl is standing there.The girl who is standing there is Mary.如何改写定语从句1、找准主句和从句,并找出两个简单句的共有成分,确定先行词;2、将从句中的共有成分去掉;3.找准关系词,用关系词引导从句剩下的部分,并紧接在被修饰词先行词之后;例2：A plane is a machine. The machine can fly.例3：The girl is Mary. We saw her yesterday.C定语从句选择关系词三步曲：第一找出先行词；第二看先行词在定语从句中的语法功能做主语、宾语或状语；第三选择合适的关系词;Ⅱ. 几个关系代词的基本用法：●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 letter that/which is written in pencil is difficult to read. 主语2. Do you know the gentleman that/who spoke just now3. You can take anything that you like. 宾语4. What is the question that/which they are talking about5. Here is the man who/whom/that you want to see.●which: 指物；在定语从句中作主语,宾语如：1. The book which/that was on the desk was bought by my father.主语2. The book which/that I bought yesterday is very interesting.宾语3. He was proud, which his brother never was. 表语●who, whom, whose:who: 主格, 在从句中作主语,在口语或非正式用法中作宾语; 只可指人whom: 宾格,在从句中作宾语; 只可指人whose: 属格,在从句中作定语,可指人也可指物;I like the students who/that work hard. 主语All who heard the story were amazed. 代词如he, they, any, those, all, one等后多用who.He's a man from whom we should learn. 宾语= He's a man whom/who/that we should learn from.A child whose parents are dead is called an orphan.指人I'd like a room whose window faces south. 指物whose +n. =the +n. + of which 物= of which 物+ the +n.=I'd like a room of which the window faces south. whose + n. =the +n. + of whom人= of whom人+ the +n.=I'd like a room the window of which faces south.注意：定语从句中的谓语动词的单复数于先行词保持一致This is one of the best books that have ever been written.He is one of the students who study hard at school.当one前面有the only等限定词和修饰语时, 定语从句的谓语动词要与one保持一致而取单数形式例如This is the only one of the best books that has ever been written.He is the only one of the students who studies hard at school.Ⅲ. 几个易混淆的关系代词的比较:●宜用that, 而不宜用which 的情况.①先行词为不定代词表示物,all, much, something, everything, anything ,nothing, none, the one等,②先行词被only, any, few, little, no, just, very, one of等词修饰时;③先行词是序数词时或被序数词修饰时;④先行词是最高级或被最高级修饰时;.⑤先行词既有人又有物,用which和who都不适合,这时宜用that. 如：⑧主句是There be 结构,修饰其主句的定语从句宜用that 作关系代词. 如：1. There is still a seat in the corner that is still free.⑨被修饰成分为表语时,或者关系代词本身是定语从句的表语时,该关系代词宜用that .2. My home village is no longer the place that it used to be .●定语从句中宜用which而不宜用that 的情况:①当关系代词的前面有介词时.1.A zoo is a park in which many kinds of animals are kept for exhibition.②在非限制性定语从句中.1.Crusoe's dog, which was are now very old, became ill and died .2.More and more people are beginning to learn English, which is becoming very popular in our country. which 指代主句B who & that:● who 和that 指代人时,有些情况宜用who, 而不宜用that①先行词为anyone, anybody, those, all, one, ones, they, he, people时. 如：.②在There be 结构中,修饰主语的定语从句宜用关系代词who 指代人. 如：1.There is a gentleman who wants to see you .Ⅳ.关系副词引导的定语从句:●When 指时间,在定语从句中作时间状语;定语从句中when=in/on/at which, 其先行词是表时间的名词如：time, day, week, tear, month, etc.I still remember the day when /on which my brother joined the army.作状语I shall never forget the day when Shen Zhou Ⅴwas launched, which has a great effect on my life.I still remember the days which/that we spent together. 作宾语Next winter which/that you'll spend in Harbin, I'm sure, will be exciting.●Where 指地点,在定语从句中作地点状语;定语从句中where=in/on/at which,其先行词是表示地点的名词,如：place, school, factory, room, etc.This is the factory where /in which he worked last year. 作状语This is the place where I was born.This is the park which/that they visited last year. 作宾语I live in the room which was bought by my father.I think you have got to the point where a change is needed, or you would fail.He's got himself into a dangerous situation where he's likely to lose control of the plane.●Why 指原因,在定语从句中作原因状语;先行词为reason 时,可用for which指代；如：That’s the reason why/for which he was late.The reason why / for which he didn't attend the meeting was that he was ill.I don't believe the reason that/which he gave me. 作宾语Have you asked him the reason t hat may explain his success 作主语当先行词为way时,关系词在句中作状语时,定语从句常用that, in which引导,that常可以省略;way后的定语从句的引导词不用时较多;但如果关系词在句中作主语或宾语时,则用which或that 引导;如:This is the way that /in which I do such things.比较: Please do the experiment in the waythat/whichI have shown you.V.介词+关系代词考点1.基本考点考点1 简单介词+关系代词引导定语从句时,that和who不能用于介词之后,能用于介词＋关系代词引导定语从句的代词只有which和whom;考查“介词+ 关系代词”引导的定语从句,关系代词前该选什么样的介词,要根据不同的语境、词组搭配、习语、惯用法等来决定,归纳起来介词的选择主要依据如下几点：①介词与定语从句的先行词搭配;如：The farm on which I once worked has taken on a new look．on the farm②介词与从句中动词搭配;如：Who is the man with whom our teacher is shaking hands shake hands with sb.In the dark street there wasn’t a single person to whom she could turn for help. turn to sb. for help③介词与定语从句中的形容词搭配,如：The west lake, for which Hang Zhou is famous, is a beautiful place. be famous for④根据句子的意思来决定, 此时不但要注意其前的搭配也要注意其后的搭配;Water is very important for us without which we can’t live.2004辽宁The factory produces half a million pairs of shoes every year, 80% of which are sold abroad．2006辽宁I was told that there were about 50 foreign students studying Chinese in the school, most of whom were from Germany.The old man has two daughters．Both of them are doctors．那位老人有两个女儿,她们都是医生;③as 常用在as we all know；as you know; as is known to all; as you see; as we can see; as has been expected 等结构中;例如：一般译为"正如""就像","这一点"As we all know, smoking is harmful to one's health . as 作宾语=As is known to all, smoking is harmful to one's health . as 作主语=It's known to all that smoking is harmful to one's health .=Smoking is harmful to one's health, as we all know .as 作宾语Jack has won the first prize, as often happens. 像往常一样,Jack得了一等奖;训练题汇总◆EX1用适当的关系词填空.1.

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指引，关系词放在先行词与定语从句之间起连结作用，同时又作从句中的一个成帧 ?指引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 往常能够省略，但在正式文体中往常用 whom, 不行省略；用于指物的关系代词 which 和 that 在非正式文体中也往常省略，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”这一构造在定语从句中既能作主语（如上 a 句），又能作宾语（如上 b 句）。

定语从句一、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帧?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,city, town, country等，如：This is the hotel where they are staying.I forget the house where the Smiths lived.注：where有时也可以省略。
如：This is the place (where) we met yesterday.3．why指原因或理由，它的先行词只有reason。
如：That is the reason why he is leaving so soon.注：why时常也可以省略。
如：That is the real reason he did it.(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 when my hometown was liberated.I’ll never forget the days which/that we spent together last summer.His father works in a factory where radio parts are made.His father works in a factory which/that makes radio parts.3．when和where既可以引导限制性定语从句，也可以引导非限制性定语从句。
而why 只能引导限制性定语从句。
三．限制性定语从句与非限制性定语从句1．限制性定语从句说明先行词的情况，对先行词起限定作用，与先行词关系十分密切，不可用逗号隔开，也不可省略，否则全句意义就不完整。
如：This is the telegram which he refers to.Is there anything (that) I can do for you?2．非限制性定语从句只是对先行词作补充说明，没有限定作用，它与先行词的关系比较松散，因而不是关键性的，如果省略，原句的意义仍然完整。
这种从句在朗读时要有停顿，在文字中通常用逗号与主句隔开。
如：This note was left by Tom, who was here a moment ago.As a boy, he was always making things, most of which were electric.引导非限制性定语从句的关系词有：who, whom, whose, which, when 和where，不可以用that和why。
另外，非限制性定语从句从意义上讲，相当于一个并列句，在口语中使用并不普遍，在日常生活中，人们通常用并列句或简单句来表达。
如：I told the story to John, who later did it to his brother.= I told the story to John, and he later told it to his brother.Yesterday I happened to see John, who was eager to have a talk with you.= Yesterday I happened to see John and he was eager to have a talk with you.3．两种定语从句的内涵不同，限制性定语从句具有涉他性，而非限制性定语从句具有唯一性，这在理解和翻译时应特别注意。
试比较：All the books there, which have beautiful pictures in them, were written by him.All the books there that have beautiful pictures in them were written by him.His brother, who is eighteen years old, is a PLA man. （只有一个）His brother who is a PLA man is eighteen years old. （不止一个）4．有时，非限制性定语从句所修饰的不是某一个词，而是整个主句或是主句中的一个部分，这时一般采用which 或as来引导。
如：He passed the exam, which/as he hoped he would.注：（1）as引导的从句可以放在主句之前，而which引导的从句只能放在主句之后。
They are hollow, which makes them very light.As is known to all, Taiwan is a part of China.（2）从意义上讲，which指前面主句的内容；而as指代的是作为一般人都知道的常识性的东西，因此常译成“就象… …那样”。
（3）如果定语从句的内容对主句的内容起消极作用，则用which，而不用as，如：She stole her friend’s money, which was disgraceful.He tore up my photo, which upset me.5．在正式文体中，以the way为先行词的限制性定语从句通常以in which或that 引导，如：The way in which you answered the questions was admirable.但在非正式文体中，人们通常省略in which或that :The way (in which) he spoke to us was suspicious.I don’t like the way (that) you laugh at her.四．关系词的选择1．在非限制性定语从句中，关系代词作主语，只能用who 指人，which指物；关系代词做宾语，常用whom （口语中有时用who）指人，which指物，它们都不能用that代替。
