高考英语语法定语从句讲解与练习附答案
定语从句与高考定语从句是高考的热点，主要考查关系代词和关系副词的正确运用，特别是它们在非限制性定语从句中的运用。
主要考点有：1.关系代词who, which, that, whom, as, whose的基本用法。
2.关系副词when, where, why的基本用法。
3.定语从句中关系词的特殊用法。
4.定语从句中“介词＋关系代词”介词的确定。
5. which/ as引导的非限制性定语从句的区别。
一、定语从句的分类限制性定语从句定语从句非限制性定语从句二、限制性定语从句和非限制性定语从句的区别区别一：形式不同限定性定语从句主句和从句之间不用逗号隔开；而非限定性定语从句与主句之间通常____用___逗号隔开。
区别二：功能不同限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意____不明确___；而非限定性定语从句用于对先行词起补充说明作用，如果省略，句意不影响。
如：People who take physical exercise live longer. 进行体育锻炼的人活得长些。
(若把从句去掉句子就失去意义)His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿，下星期回来。
(若把从句去句子意义仍然完整)比较下面的两个句子：I have a sister who is a doctor. 我有一个当医生的姐姐。
(姐姐不止一个)I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。
(只有一个姐姐)区别三：翻译不同在翻译定语从句时，一般把限定性定语从句翻译在它所修饰的先行词之前，而把非限定性定语从句与主句分开。
如：He is the man whose car was stolen. 他就是汽车被窃的那个人。
I’ve invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。

高中定语从句讲解与练习（附答案）定语从句专项讲解与练习1、定语从句在句中修饰某个名词或代词，被定语从句修饰的词叫先行词。
定语从句需用下列关联词：关系代词和关系副词。
它们起连词作用，本身做从句的主语、宾语、表语或定语，本身在从句中作时间、地点或原因状语。
主要有who, whom, that, whose, which, as, when, where, why。
PS:what不能引导定语从句. 指人的关系代词有who、whose、whom、that. 指物的关系代词有which、whose(=of which)、that.The old man who/whom /that we visited yesterday is a famous artist.Miss Wang is taking care of the child whose parents have gone to Beijing .The man with whom my father shook hands just now is our headmaster. （=The man who/whom/ that my father shook hands with just now is our headmaster.）I like the books which / that were written by Lu Xun.The desks (which/that) we made last year were very good.This is the house in which we lived last year. (= This is the house which /that we lived in last year.)I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)2、掌握以上关系代词、关系副词的含义及使用时，要特别注意以下几点：1）指人时宜用who 的情况：a. 当先行词是one, ones, anyone 或those , these 时，关系代词用who。

高中英语语法：定语从句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。
注意：关系代词和关系副词处在先行词和定语从句之间，起着连接主从句、指代先行词和在从句中作句子成分的三重作用。
一、关系代词that, which, who引导的定语从句二、关系代词whose引导的定语从句关系代词whose为关系代词who的所有格形式，用作名词的限定语，whose引导的定语从句既可为限制性的，也可为非限制性的。
先行词既可为人，也可为物，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。
例如：This is the scientist whose name is known all over the world.The room whose window faces south is mine.He has written a book whose name I’ve forgotten.=He has written a book the name of which I’ve forgotten.四、判断关系代词与关系副词先把主句和定语从句分开，再找出定语从句所修饰的名词/代词（即先行词），然后放入定语从句中，看看这两者的搭配情况。
1）如果定语从句和该先行词可以直接相连，且在从句中充当主语/宾语/表语的话，则用关系代词。
This is the city (which/that) you visited last year.2）如果定语从句和该先行词无法直接相连，必须另外多加上介词，并在定语从句中充当状语时，则使用关系副词。
This is the city where you stayed last year.选择：1. Is this museum ___ you visited a few days age?A. whereB. thatC. on whichD. the one2. Is this the museum ____ the exhibition was held.A. whereB. thatC. on whichD. the one五、限制性和非限制性定语从句1）定语从句有限制性和非限制性两种。
高中定语从句全面详细讲解附练习题加答案
高中定语从句详细讲解【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 t eacher.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 ex pensive.(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。
高中英语高考复习定语从句知识精讲(附练习题)
高考英语定语从句知识精讲一、关系代词引导的定语从句1、that 指人或物在从句中作主语，宾语或表语；which 指物在从句中作主语，宾语或表语（作宾语时可以省略）；who 指人在从句中作主语，宾语或表语（作宾语时可以省略）；whom 指人在从句中作宾语（作宾语时可以省略）；whose 指人或物在从句中作定语；as 指人或物在从句中作主语，宾语或表语；注意：指物时，whose+名词 = the+名词+of which 或 of which + the +名词2、as 的用法（1）常用于下列结构：such…as; so…as; the same…as;注意：the same…as 表示同一类，不同一个the same…that 表示同一个（2）as与which的区别a、位置不同as可放在主句后，主句前或主句中间；which只能放在主句后。
b、as起连接作用，表达说话人的观点、看法，并指出主句内容的根据或出处，意为“正如，正像”。
which相当于并列句，可以用and this来代替，意为“这一点，这件事’”。
注意：as常用于下列结构：as we know/ as is known to all, as we all can see, as has been said before/above, as might be excepted, as is often the case, 一般不能用which 代替as。
c、在从句中作主语时，which既可作系动词be的主语也可作实义动词的主语，而as只可作系动词be的主语。
二、只用that不用which的情况1、先行词为 all, much, everything, nothing, something, anything, nothing, none, the one等不定代词时2、先行词被only, any, few, little, no , all, just , very ,right等修饰时.3、当先行词是最高级或被形容词最高级修饰时。

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/关系副词。
例1. Is this museum ___ you visited a few days age?A. whereB. thatC. on whichD. the one例2. Is this the museum ____ the exhibition was held.A. whereB. thatC. on whichD. the one例1变为肯定句：This museum is ___ you visited a few days ago.例2变为肯定句：This is the museum ___ the exhibition was held.在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。
而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因in the museum 词组，可用介词in + which 引导地点状语。
而此题中，介词on 用的不对，所以选A。
关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词（who, whom, that, which, whose）；先行词在从句中做状语时，应选择关系副词（where 地点状语，when 时间状语，why 原因状语）。
18.4 限制性和非限制性定语从句1）定语从句有限制性和非限制性两种。
限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开。
例如：This is the house which we bought last month. 这是我们上个月买的那幢房子。
（限制性）The house, which we bought last month, is very nice. 这幢房子很漂亮，是我们上个月买的。
（非限制性）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.查理.史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。
3）非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。
例如：He seems not to have grasped what I meant, which greatly upsets me.他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。
说明：关系代词that和关系副词why不能引导非限制性定语从句。
18.5 介词+关系词1）介词后面的关系词不能省略。
2）that前不能有介词。
3）某些在从句中充当时间，地点或原因状语的\"介词+关系词\"结构可以同关系副词when 和where 互换。
例如This is the house in which I lived two years ago. 这是我两年前住过的房子。

As 一般放在句首，which在句中。
例如：As we know, smoking is harmful to one\'s health. 如我们所知，吸烟有害健康。
The sun heats the earth, which is very important to us. 太阳使地球暖起来，这对我们人类很重要。
典型例题1）Alice received an invitation from her boss, ___came as a surprise.A. itB. thatC. whichD. he答案C. 此为非限定性从句，不能用that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。
况且选he句意不通。
2）The weather turned out to be very good, ___ was more than we could expect.A. whatB. whichC. thatD. it答案B。
which可代替句子，用于非限定性定语从句，而what不可。
