限制性定语从句提供有关主语或宾语的重要信息，起限定作用，与被修饰部分的关系紧密，如果省略该从句会使主句语义表达不完整。例如：
This is the very person that is wanted by the police.
He is the man who /that lives next door.
非限制性定语从句只是用来对被修饰部分作补充性的说明，与先行词关系比较松散，先行词与从句间可以用逗号隔开，从句可略去：
The minister, who is to visit our university, is said to be a Qinghua University graduate.
The businessman, whose suitcase has been found by a stranger, has left for Beijing.
如果定语从句的先行词是专有名词或是带有形容词性物主代词(my, his, etc)或形容词性指示代词(this, that, etc)作限定词的名词词组，其后的定语从句通常为非限制性的。
例如：
My mother, who has been on a visit to Australia, will fly back tomorrow..
限制性定语从句的先行词只能是名词，代词或名词性词组，而非限制性定语从句的先行词除了是名词及名词性词组外，还可能是句子的一部分或是整个句子。例如：They say he plays truant, which he doesn’t. [which指代plays truant]
The meeting was put off till next month, as we hoped. [as指前面的句子]
下面的表格归纳了前面已提到的两者不同之处：
as的用法
1、as引导限制性定语从句时，常与such或the same连用，构成the same…as; such…as
结构，as用于代替指人或物的先行词。例如：
I have never eaten such tasty foods as she cooked me.
试比较the same…as和the same…that：
This is the same book as I read last week.（这和我上周读的那本书是一样的。）
This is the same book that I read last year.（这就是我上周读的那本书。）如果先行词表示抽象概念，则没有这种区别，例如：
She told me the same story as/that she had told you.
在as／so…as结构中，后面的as也是关系代词，例如：
We took as many men as could be permitted to attend the meeting.
2、引导非限制性定语从句
关系代词as引导非限制性定语从句时，用于代替整个主句，意思是“正如”，相当于and this或and that。as从句位置较之which引导的非限制性定语从句更加灵活，因而as从句既可以指前面提到的内容，也可以指后面将要提到的内容，which一般在主句后。例如：
The test is cancelled, as you have hoped.
The test, as you have hoped, is cancelled.
▲注：as代表前面的整个主句并在从句中做主语时表达的意思应与主句一致，而且从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.例如：He failed to pass the exam again, as is predicted.
He failed to pass the exam again, which annoyed his mother greatly.
记住以下的as结构：
as is known to all (众所周知)，as is often the case (情况常常如此)，as the name Indicates／suggests (顾名思义)，as may be imagined (可以想象得出)，as often happens (这种情况常常发生)，as has been said before (如前所述)，as has been pointed out (正如已经指出的)，as will be shown in ( 将在…中指出)，as is hoped ( 正如所希望的)
3 介词+ 关系代词
“介词+ 关系代词”引导的定语从句既可以是限制性定语从句，又可以是非限制性定语从句，“介词+关系代词”在从句中做主语、宾语、状语、定语等，介词的选择则要根据它与其先行词的关系或前后名词、动词等的搭配关系来决定，同时还应该考虑句子在上下文中要表达的意思。
4.“介词+ which／whom／whose”
这时应注意介词与句中短语的搭配。例如：
The problem with which I have trouble has now been solved.
介词放在关系代词之前的形式的定语从句较之将介词至于从句之末的定语从句正式，因此多用于书面语当中，但在口语中有时也会出现；或者将介词后置，或在介词后置后用that（人、物）／who（人）代替which／whom，并且that可省略。例如；
Can you lend me a pen or pencil with which I can write?
Can you lend me a pen or pencil that/ which I can write with?
5.“介词+ which + 名词”引导的定语从句
which是一个代表所有关系的关系代词，可用来代表一个名词／代词或句子的一部分，但更多地是来代表整个句子。其中的名词通常是一个抽象名词，如case, fact, state, time, point等。例如：
Water boils at l00℃, at which temperature it changes into gas.
He was about to leave, at which moment I came back home.
6.定语从句中的关系副词
关系副词引导的定语从句（限制性／非限制性）在从句中作状语，意思相当于“介词+which”，常见的引导定语从句的关系副词有：where, when和why等，不常见的如表示时间的关系副词：since, after和before。
7.关系副词where（= at, in which）引导表示地点的定语从句
This is the place where he’d most like to live the rest of his life.
That is the place where they met for the first time.
在表示“情况、方面、状况”等有地点含义的抽象名词如case, game, spot, point, conditions, situation, circumstances等作为先行词的定语从句时，也用where引导, 其意义相当于under which。例如：
It’s a kind of game where you can train your eyesight
8.关系副词when（= at, on, during, in which）引导表示时间的定语从句
I’ll never forget the day when (=on which)I first came to this university.
This is the season when (=in which)most fishers will be very busy.
9. 关系副词why（= for which）引导表示原因的定语从句
Do you know the reason why he left the party early that night?
The reason why she missed the train is that she was held up by an accident.
10. 关系代词与关系副词的判断
看①谓语动词是否及物
用关系代词还是关系副词完全取决于从句中的谓语动词。从句中如果及物动词后面接宾语，就必须要用关系代词；而不及物动词则要求用关系副词。例如：The days when we stayed together are unforgettable.（stay不及物）I’ll never forget the days which I spent with you in Tokyo .（spend及物，有宾语）
This is the reason why he did not come that morning.(come不及物动词)
This is the reason which/ that he found to excuse for himself. (find及物动词)
②先行词在定语从句中的成分（主、谓、宾、定、状）
先行词表示时间、地点或原因时，就选用关系副词，用when，where或why，在从句中应该是做状语，否则的话则应该用which／that等，that有时可以代替when，where
或why，但when，where或why中不能代替that。例如：
1. Is this museum you visited a few days ago?
A. where
B. that
C. on which
D. the one
2. Is this the museum the exhibition was held.
A. where
B. that
C. on which
D. the one
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；而在句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。
当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导。例如：
I don’t want to concentrate on anything there is worrying me.
限制性定语从句和非限制性定语从句六大区别及练习
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，口语中使用时也不停顿；而非限定性定语从句与主句之间通常有逗号隔开，口语中使用时有停顿。
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，就会造成句意不完整或概念不清；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，句意仍然清楚、完整。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)
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。
区别四：含义不同
比较下面的两个句子：
I have a sister who is a doctor. 我有一个医生的姐姐。(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)
区别五：先行词不同
限定性定语从句的先行词只能是名词或代词，而非限定性定语从句的先行词则可以是名词或代词，也可以是短语或句子；另外，当先行词为专有名词或其他具有独一无二性的普通名词时，通常要用非限制性定语从句，而不用限制性定语从句。如：
Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。(which指drive too fast) He changed his mind, which made me very angry. 他改变了主意，这使我很生气。(which指整个主句) Mr. Smith, who is our boss, will leave for Japan next week. 我们的老板史密斯先生下周要去日本。(先行词为专有名词，要用非限制性定语从句修饰)
Her father, who has a lot of money, wishes her to study abroad. 她父亲很有钱，希望她出国学习。(先行词为表独一无二意义的普通名词，要用非限制性定语从句修饰)
区别六：关系词不同
关系词that和why可用于限制性定语从句中，通常不用于非限制性定语从句；另外，在限制性定语从句中，关系词有时可以省略(参见本章有关内容)，而在非限制性定语从句中关系词一律不省略。

关系副词引导的定语从句 一.关系副词where引导的定语从句。 where引导的定语从句其先行词往往是表示地点的名词。 1.China is the only country where wild pandas can be found. 2.This is the house where I lived two years ago. 知识拓展： 如果定语从句分别修饰point, situation, stage, condition和case, position 等表示抽象意义的词，常用where / prep + which引导，意思是“到了某种地步，在某种境况中”。 I’ve come to the point where I can’t stand him. I have reached a point in my life where I am supposed to make decisions of my own. 练一练 1. It’s helpful to put children in a situation _______ they can see themselves differently. 2. Life is like a long race _____we compete with others to go beyond ourselves. 3. They will fly to Washington, ___ they plan to stay for two or three days. 二．关系副词when引导的定语从句 when引导的定语从句其先行词往往是表示时间的名词。 The time when I first met Nelson Mandela was a very difficult period of my life. Ｉcan’t forget the year when I studied English in Beijing University. 练一练： 1. Because of the financial crisis, days are gone _____ local 5-star hotels charged 6,000 yuan for one night. 2. We went through a period ___ communications were very difficult in the rural areas. 3. Occasions are quite rare _____ I have the time to spend a day with my kids. 三．关系副词why 引导的定语从句。why引导的定语从句其先行词是reason。 The reason why he didn’t come to the party is that he didn’t want to see Jane. Can you tell me the reason why you are late? 练一练 1) The reason ________he didn’t come was that he was ill. 2) The reason __________ he explained is not true. 3) The reason ___ he was absent was ___ he had a bad cold. 四．“介词+ 关系代词”引导的定语从句:介词后的关系代词只能是which （指物）whom（指人）
非限制性定语从句 一、与限制性定语从句的区别： 限制性定语从句是不能去掉的，否则剩下的部分就失去意义而不能成立。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，去掉之后并不影响整个句子的含义。在形式上，非限制性定语从句与主句之间通常必须有逗号隔开。试比较： ①A man who doesn’t want to learn from others can’t achieve much. ②I come from China, which has a long history of 3000 years. 二、as和which的区别 翻译下列句子，然后找出每句的先行词。 1. A five-year-old boy can speak two foreign languages, which surprises me. 2.The weather turned out to be very good, which was more than we could expect. 3.Tom is tall, as are his brothers. 4.As we all know, paper was first made in China. 归纳：as和which在非限制性定语从句中可代替整个主句。 as可用在固定搭配中 as anybody can see正如人人都能看到的那样 as has been said before如前所说 as often happens 正如经常发生的那样 as has been pointed out 正如已指出的 as we all known/ as is well known to us众所周知 as mentioned above如上所述 1.___________ often happens, he is late again. 2.He came here very late, ____________ was unexpected. 3.He has passed the text, ___________ nobody knows. 4.Tom has made rapid progress, ____________ makes me very happy. 5.Mother was terrified, ____________ I could see from her eyes. 6.Our team lost the game, ____________ was reported in the newspaper. 巩固练习： 一、完成句子。 1.射击最初只是生存工具，19世纪末才发展成为一项体育运动。 Shooting, _________was a means of survival originally, developed into a sport only in the late 19th century. 2.中国吸烟人数：约 3.5亿；分布：男性75％;女性：25％ Currently China has about 350 million smokers, among _________75% are men and 25% are women. 3.受二手烟影响人数：约5.4亿；因二手烟死亡人数：超过10万/年 Around 540 million people are affected by second-hand smoke, ________causes 100,000 deaths per year. 4.众所周知，2008年北京将举办奥运会。英语作为一种国际语言，将会在交流 中起着重要作用。作为一名高三学生，我们应抓住现在的学习机会努力学好它。只有这样，才能为奥运贡献自己的力量。 _________ is known to all, Beijing will host the 2008 Olympic Games. English, __________ is an international（国际的）language, plays an important part in communicating（沟通、交流）with foreigners. We Senior Three students should catch this opportunity（机会）to learn it well, by __________ we can make our contribution （贡献）to the Olympic Games. 二、英译汉。 1.Don’t cheat me. I’m no longer the boy that I was three years ago. ______________________________________________________________________ 2.There is no difficulty that cannot be overcome. ______________________________________________________________________
限制性定语从句与非限制性定语从句 2．关系代词which与as引导非限制性定语从句的区别。 （1）which与as都可以引导非限制性定语从句，which引导定语从句要置于先行词后面，而as引导的定语从句位置相对灵活，可放在句首，也可以放在句后 eg.正像他所意识到的那样，我对他非常有用 As he realized, I was very useful to him. 空气，众所周知，是一种气体 Air, as we know, is a gas. 他是个外国人，正像我从他口音判断的那样。 He was a foreigner, as I know form his accent. 他又来晚了，这一点使老板很生气 He came late again, which made his boss angry. (2)当定语从句位于主句后面，纯粹表示主句所述的内容，往往用which；当定语从句中有“如同……那样”的含义时，用as比用which更常见。 Eg.妈妈老把我当成小孩对待，让我无法忍受 Mummy always treats me just like a baby, which I can’t bear. 事与愿违，这是常有的事 Things will turn out contrary to on e’s wishes, as is often the case. (3)“介词+关系代词”结构的定语从句，必须用which,不能用as. Eg.我们周围有很多氧气，没有他们我们无法生存 There is a great deal of oxygen around us, without which we could not live. 3．引导限制性定语从句时which与as的区别 定语从句前面有such, as, the same 时，引导定语从句的关系代词用as,不用which. Eg 所需要的字典有许多都有了
志伟教育限制性定语与非限制性定语练习题 一、复习关系词的用法：（在对应用法处打钩） 1.The person _______ is standing there is my teacher. 2.The person ________ you spoke just now is my teacher. 3.The person ________ you spoke to just now is my teacher. 4.I bought a car__________ cost little. 5.The car __________ I bought yesterday cost little. 6.This school is the one _________ I studied ten years ago. 7.This is the little girl ___________ parents were killed in the earthquake. 8.The boss in ________ company my father worked is a very kind man. 9.I will remember that day __________ I first came to Beijing. 10.There are several reasons _________ we can’t do that. 1.who/that 2.to whom 3.who/whom/that 4. which/that 5. which/that 6. in which/where 7.whose 8.whose 9. when/on which 10.why/for which 二、观察下列句子并翻译 1.I’m taking weight-loss pills called Fat-Less, which are quite popular among young women here. ____________________________________________________________________ 2.My mother, who you met last year, keeps telling me not to take them because they are dangerous. _____________________________________________________________________ 3. Many people, some of whom are not overweight at all, are always going on diets or taking weight-loss pills, which are often dangerous. _____________________________________________________________________ 结论：以上三句是非限制性定语从句。 非限制性定语从句是对先行词起补充和附加说明的定语从句。通常用逗号与先行词隔开，可以修饰主句中的某个名词，也可以修饰整个主句。若省略掉非限制性定语从句，也不会影响句意的完整性。
二轮复习书面表达写作技巧之三：如何写好定语从句 定语从句的正确使用能够比较明显地反映出考生对于语言具有较高的掌握能力，所以建议考生一定要在写作中至少使用一个恰到好处的定语从句。 (一)定语从句的类型 1．关系代词引导的定语从句 关系代词who, whom, whose, that, which, as引导的定语从句是写作的一大重点，尤其是which和as引导的非限制性定语从句在高考范文中更是屡见不鲜。 ①(2018?北京高考书面表达)Last week, we took the foreign students to experience the authentic tea culture, which turned out to be extremely rewarding.上周，我们带领外国学生体验了正宗的茶文化，结果证明非常值得。 ②(2017?全国卷Ⅲ书面表达)Secondly, you will make some good friends who are also interested in playing table tennis.第二，你会交到一些好朋友，他们也很喜欢打乒乓球。 ③As you see, the Chinese people are hard-working. 你知道，中国人民是勤劳的。 2．关系副词引导的定语从句 关系副词引导的定语从句是指when, where, why引导的定语从句。
①(2018?北京高考书面表达)Its Chinese Literature major is perfect for you where you can be completely soaked in Chinese profound history and rich culture. 它的中国文学专业对你来说是适合的，在那儿你可以完全沉浸在中国深厚的历史和丰富的文化中。 ②(2014?安徽高考书面表达)I think the reason why you are always angry may be the high pressure of study. 我认为你总是发脾气的原因可能是学习上的巨大压力。 3．“介词＋which/whom”引导的定语从句 (2017?北京高考书面表达)Material collecting took us a whole week, during which we interviewed our teachers and took pictures of every aspect of school life. 搜集材料花了我们整整一周的时间，在此期间我们采访了老师并拍摄了学校生活的各个方面。 (二)定语从句的写法 定语从句是比较难掌握而又是考生在写作中喜欢尝试的复杂句，在写作时可采用“三步法”： [示例] 第一步：写出两个简单句。 ①The foreigner is from Canada. ②He visited our class yesterday.
Unit 2 Growing Pains 定语从句（2）--- 定语从句中关系副词的用法 Learning Content : Learn Attributive Clauses --- Relative adverbs: where, when, why Learning Aims: Learn how to use relative adverbs in attributive clauses Learning difficult and important points : The difference between relative adverbs and relative pronouns Period ：One 自主学习过程 关系副词是联系先行词和定语从句的词。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： 1. 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 ' nllever forget the day when I joined the army. 2. 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. 3. 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. 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 ________ my mother works. **This is the hospital ________ we visited the day before yesterday. 知识小结（判断定语从句引导词的方法） 方法一：不及物动词则要求用关系副词when, where, why, 从句中的谓语为及物动词且后面无宾语，就必须要求用关系代词； 方法二： 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选择关系副词（ where 地点状语，when 时间状语，why 原因状语） 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）

限制性定语从句与非限制性定语从句的六点区别 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，口语中使用时也不停顿；而非限定性定语从句与主句之间通常有逗号隔开，口语中使用时有停顿。 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，就会造成句意不完整或概念不清；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，句意仍然清楚、完整。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) 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。 区别四：含义不同 比较下面的两个句子： I have a sister who is a doctor. 我有一个医生的姐姐。(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) 区别五：先行词不同 限定性定语从句的先行词只能是名词或代词，而非限定性定语从句的先行词则可以是名词或代词，也可以是短语或句子；另外，当先行词为专有名词或其他具有独一无二性的普通名词时，通常要用非限制性定语从句，而不用限制性定语从句。如： Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。(which指drive too fast) He changed his mind, which made me very angry. 他改变了主意，这使我很生气。(which 指整个主句)
非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，在非限定性定语从句的前面往往有逗号隔开，如若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，将非限定性定语从句放在句子中间，其前后都需要用逗号隔开。 which引导的非限制性定语从句。 关系代词which在非限制性定语从句中所指代和修饰的可以是主句中的名词、形容词、短语、其他从句或整个主句，在从句中作主语、动词宾语、介词宾语或表语。 ① which指代主句中的名词，被指代的名词包括表示物、婴儿或动物的名词、表示单数意义的集体名词以及表示职业、品格等的名词。 如：These apple trees，which I planted three years ago，have not borne any fruit. 这些苹果树是我三年前栽的，还没有结过果实。 She is an artist，which I am not. 她是一位艺术家，而我不是。 Water，which is a clear liquid，has many uses. 水是一种清澈的液体，有许多用途。 The two policemen were completely trusted，which in fact they were. 那两个警察完全受到信任，事实上，也真是如此。 ② which指代主句中的形容词。 如：She was very patient towards the children，which her husband seldom was. 她对孩子们很耐心，她丈夫却很少这样。 She is always careless，which we should not be. 她总是马虎大意，我们可不应该这样。
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
定语从句 用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起 定语作用的句子叫作定语从句。 一．词引导的定语从句 1. 关系代词用来指代先行词是人或物的名词或代词 句子成分用于限制从句或非限制性从句只用于限制性从句 代替人代替物代替人或物 主语 Who which that 主语 Whom which that 宾语 Whose(=of whom) whose(=of which) 例1：This is the detective who came from London. 例2：The book which I am reading is written by Tomas Hardy. 例3：The desk whose leg is broken is very old. 例4：This is the room that Shakespeare was born in. 2．关系代词的用法 (1) 如果先行词是all, much, anything, something, nothing, everything, little, none等不定代词，关系代词一般只用that，不用which。例如： All the people that are present burst into tears. (2) 如果先等词被形容词最高级以及first, last, any, only, few, much, no, some, very等词修饰，关系代词常用that,不用which, who，或whom。例 如： (3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不 能省略。例如：

非限定性定语从句是英语语法中从句的一种，是定语从句的分支之一。作用是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立。运用非限定性定语从句，尤其要注意其语法运用及其所表示的东西。 1 who引导的非限制性定语从句 Our guide，who was a French Canadian，was an excellent cook. 我们的向导，一个法裔加拿大人，擅长于烹调。 My gardener，who is very pessimistic，says that there will be no apples this year. 我家的园丁非常悲观，他说今年将不结苹果。 2 whom引导的非限制性定语从句。 关系代词whom用于指人，在句中作动词宾语和介词宾语，作介词宾语时，介词可位于句末。 如：Peter, whom you met in London, is now back in Paris. 彼得现在回巴黎了，你在伦敦见过他。 Mr Smith，from whom I have learned a lot，is a famous scientist. 史密斯先生是一位著名的科学家，我从他那儿学了许多东西。 3 whose引导的非限制性定语从句。 whose是关系代词who的所有格形式，在从句中作定语。whose通常指人，也可指动物或无生命的事物。 如：The boy, whose father is an engineer, studies very hard. 那位小男孩学习很努力，他的父亲是位工程师。 Above the trees are the mountains, whose magnificence the river faithfully reflects on the surface. 在树林的高处是山，其壮丽的景色完全映照在河面上。 The play，whose style is rigidly formal，is typical of the period. 这剧本是那个时期的典型作品，风格拘谨刻板。 4 which引导的非限制性定语从句。 关系代词which在非限制性定语从句中所指代和修饰的可以是主句中的名词、形容词、短语、其他从句或整个主句，在从句中作主语、动词宾语、介词宾语或表语。 ①which指代主句中的名词，被指代的名词包括表示物、婴儿或动物的名词、表示单数意义的集体名词以及表示职业、品格等的名词。 如：These apple trees，which I planted three years ago，have not borne any fruit. 这些苹果树是我三年前栽的，还没有结过果实。 She is an artist，which I am not. 她是一位艺术家，而我不是。 Water，which is a clear liquid，has many uses. 水是一种清澈的液体，有许多用途。 The two policemen were completely trusted，which in fact they were. 那两个警察完全受到信任，事实上，也真是如此。 ②which指代主句中的形容词。 如：She was very patient towards the children，which her husband seldom was. 她对孩子们很耐心，她丈夫却很少这样。 She is always careless，which we should not be. 她总是马虎大意，我们可不应该这样。 ③which指代主句中的某个从句。
