非谓语动词做定语

直接修饰名词的成分称为定语，一般由形容词或名词担当，也可以分别由不定式、分词或动名词等非谓语动词来担当。那么如何区别并正确使用非谓语动词呢？

NON-FINITES

1. 现在分词与过去分词的区别

我们知道非谓语动词都源于及物和不及物两种谓语动词，要了解现在分词与过去分词的区别就要从谓语动词的基本属性开始。

1)及物动词 (v.t.)

及物动词的主语我们称为动作的发出者(sender)，宾语称为动作的承受者(receiver)。

例如：

The news surprised

动词+ing (发出者) 及物动词v.t.

the students.

动词+ed (承受者)

Surprise是及物动词， 在使用surprise这个动词的非谓语分词形式时，修饰动作发出者news用现在分词形式(动词+ing)，修饰动作的承受者用过去分词形式(动词+ed)。

●They are talking about the surprising news. (surprising做定语修饰发出者news)

The news is surprising. (surprising做表语修饰发出者news)

They are talking about the surprised students. (surprised做定语修饰承受者students)

The students are surprised. (surprised做表语修饰承受者students)

再来看几个例子：

●exciting games激烈精彩的比赛, excited spectators激情振奋的观众

●disappointing results令人沮丧的结果, disappointed people大失所望的人们

●exhausting work令人疲惫不堪的工作, exhausted workers筋疲力尽的工人

●moving stories感人肺腑的故事, moved students感激涕零的学生

从以上例子可见，现在分词和过去分词都可以用作形容词来修饰名词，修饰动作发出者用现在分词，修饰动作承受者用过去分词。要特别注意的是，依据被修饰的名词是人还是物来判断现在分词和过去分词的用法是不准确的。

例如： They complicated the situation by introducing some more restriction.

他们采用了一些更多的限制把形势复杂化了。

及物动词complicate的发出者是人they, 而承受者是物。因此，“复杂恶化的形势”应译为the complicated situation，“形势是令人棘手的” 应译为The situation is complicated.

从这个例子可以清楚地看出，如果根据中文，很容易将“令人棘手的形势”错误地理解为 “complicating situation”。

再比如我们常用的：

a broken cup 一个破杯子; spoken English英语口语;exported products出口产品。

因此，准确了解所修饰的名词与及物动词的关系，是正确使用及物动词的现在分词和过去分词的关键。

2) 不及物动词(v.i.)

不及物动词只有动作的发出者，不存在动作的承受者。因此，不及物动词的现在分词源于进行时，表示动作正在进行，而过去分词则源于完成时，表示动作已完成。

例如：

●He looked at the leaves which are falling in the air.(从句用进行时修饰名词the leaves)

他看着空气中飘然下落的叶子。

=He looked at the leaves falling in the air.(现在分词短语修饰名词the leaves表示进行)

=He looked at the falling leaves in the air. (现在分词修饰名词the leaves表示进行)

●He walked on the leaves which had fallen on the ground.(从句用完成时修饰名词the leaves) 他走在地面的落叶上。

He walked on the leaves fallen on the ground.(过去分词短语修饰名词leaves表示过去)

He walked on the fallen leaves on the ground. (过去分词修饰名词leaves表示过去)

●the rising sun. = the sun that is rising. 冉冉升起的太阳

the risen sun = the sun that has risen. 已经升在天空的太阳

●boiling water = water which is boiling. 沸腾的水

boiled water = water which has boiled 开过的水

2. 不同形式不定式做定语的区别

动词不定式的一般式可以用做形容词，担当名词的定语, 表示将要发生的动作，不定式的进行式和完成式都不可以用作定语。

1)及物动词不定式一般式主动to do sth和被动to be done 两种形式的区别。

例如：

●Have you anything to send? = Have you anything that you will send?

你有什么东西要(自己)寄吗？(主动含义，动作由you自己去完成)

(to send做定语, 源于定语从句that you will send, 修饰先行词anything, 表示将来。)

●Have you anything to be sent (by others)?=Have you anything that will be sent(by others)?

你有什么东西要(我或别人)寄吗？(被动含义，动作由他人others去完成)

(to be sent做定语, 源于定语从句that will be sent, 修饰先行词anything, 表示将来。)

从以上两个例子可以看出，不定式的主动形式to send来源于主动语态的定语从句。

而不定式的被动形式to be sent来源于被动语态的定语从句, 不能错误地认为to send 是主动形式表示被动，准确地讲应该牢记主动形式的不定式源于主动语态的从句，被动形式的不定式则源于被动语态的从句，两者绝不可以混淆。

●I have some books for you to read. = I have some books that you should read.

我有几本书希望你读一读。

(for you to read做定语, 源于定语从句that you should read, 修饰先行词books, 表示将来。原从句的主语you在不定式的前面以for you 的形式出现，担当不定式的逻辑主语。)

2)不及物动词不定式一般式做定语

当不及物动词做定语时, 后面必须有相应的介词与前面所修饰的名词相呼应, 从汉语角度理解，而忽略了必要的介词是不及物动词做定语时常见的错误。

例如：

●He is looking for a room to live in.= He is looking for a room which he will live in.

他现在正在找房间住。

(to live in做定语, 源于定语从句which he will live in, 修饰先行词room, 表示将来。)

●Would you like to have another pen to write with? ( to write with the pen)

你需要再准备一支笔用吗？

●Smith is a good man to work with. ( to work with the man)

与史密斯一起工作是再好不过了。

●Lei Feng is a brilliant example for us to learn from. ( to learn from the example)

雷锋是我们学习的光辉榜样。

●Can you lend me a chair to sit on?

您可以借给我一把椅子坐吗？

●Global Financial Crisis is a hot topic to talk about today. ( to talk about the topic)

全球性金融危机是当前人们谈论的热点话题。

2011届高三英语定语从句第一轮复习语法

高中英语定语从句说课稿

　定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词。它是高中英语学习的重要语法项目之一，也是历年高考的热点。如下是我给大家整理的高中英语定语从句说课稿，希望对大家有所作用。

　 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) 引导定语从句的词叫关系词，分为关系代词和关系副词。

　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）

　常用的关系代词: that、 which、 who、whom、as , 在从句中作主语，宾语，whose在从句中作定语)

　常用的关系副词（在从句中只作状语）: when、why、 where

　The student who answered the question was John.

　I know the reason why he was so angry.

　The boy (whom) you are talking to is my brother.

　I'd like a room whose window looks out over the sea.

　定语从句三步：

　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)(不用于非限制性定语从句; 不可置于介词后作宾语) 如：

　1. Do you know the gentleman that/who spoke just now?

　2. You can take anything ( that) you like.

　3. What is the question (that/which) they are talking about?

　4. Here is the man ( who/whom/that ) you want to see.

　5. She's no longer the girl ( that) she used to be before.

　●which: 指物；在定语从句中作主语，宾语，表语，定语。如：

　1. The bookwhich/that was on the desk was bought by my father.

　2. The book (which/that) I bought yesterday is very interesting.

　3. The factory in which his father works is far from here.

　●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。

　1. I like the students who/that work hard.

　2. All who heard the story were amazed.

　(代词如he, they, any, those, all, one等后多用who.)

　3. He's a man from whom we should learn.

　= He's a man (whom/who/that) we should learn from.

　4. A child whose parents are dead is called an orphan.

　5. I'd like a room whose window faces south.

　=I'd like a room of which the window faces south.

　=I'd like a room the window of which faces south.

　关系代词作介词宾语： （介词+ whom / which）

　关系代词在定语从句中用作介词宾语时, 介词可放于从句之首, 也可放于从句之末. 但以放于句首较为正式.（介词前置，必须注意不影响动词词组的含义。）

　1. This is the book for which you asked. =This is the book (that/which) you asked for.

　2. Do you know the person with whom I shook hands？

　= Do you know the person (whom/who/that) I shook hands with?

　3. Is this the factory to which you paid a visit last week?

　4. Is this factory the one to which you paid a visit last week?

　5. This is the girl whom they are looking after. (介词after与look构成固定词组，不可前置。look at, look for, look after, take care of等)

　●as 的.用法:(as 引导定语从句, 在定语从句中作主语、宾语、表语)

　①如为限制性的，多用于the same …as ; the same as；such …as …; as many/much as；so …as等结构中。

　1. I have the same book as you (have). 我有一本和你的一样的书。

　2. .---Why didn't you mention that in face of the police just now?

　--- I thought it was such a minor detail as was hardly worth mentioning.

　3. Don't do such things as you are not sure about.

　比较：I live in the same house that he used to live in.

　I'm wearing the same shirt as you wore yesterday.

　比较：Here is so big a stone as no one can lift. （定语从句）

　Here is so big a stone that no one can lift it.（结果状语从句）

　②如为非限制性的，多单独引导一个定语从句，这种定语从句可置于句首，句中或句尾，译为"正如，这一点"。（动词常为know, see, expect, point out, etc.）

　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）

　=Smoking, as we all know, is harmful to one' health.

　He was a foreigner, as I knew from his accent. (宾语, 先行词是前面整个句子)

　 Ⅲ. 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。其先行词是表时间的名词（如：time, day, week, tear, month, etc.）

　He came last night when I was out.

　We will put off the picnic until next week, when the weather would be better.

　注意：先行词为"时间名词"，可用when引导定语从句，when在定语从句中作状语；还可以用which或that 引导，which或that在从句中作主语或宾语。

　比较:1. I still remember the day when /on which my brother joined the army.（作状语）

　2. I still remember the days which/that we spent together. （作宾语）

　3. I shall never forget the day when Shen Zhou Ⅴ was launched, which has a great effect on my life.

　●Where 指地点，在定语从句中作地点状语。其先行词是表示地点的名词，如：place, school, factory, room, etc.

　This is the place where I was born.

　I live in the room where /in which he used to live.

　注意：先行词是"地点名词"，定语从句可用where引导，还可用which或that引导，which/that 在从句中作主语或宾语。

　比较: ※1. This is the factory where /in which he worked last year. （作状语）

　2. I think you have got to the point where a change is needed, or you would fail.

　3. He's got himself into a dangerous situation where he's likely to lose control of the plane.

　4. This is the park which/that they visited last year. （作宾语）

　●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；当关系词在从句中作主语或宾语时，则用which或that 引导。如：

　1. The reason why / for which / (that) he didn't attend the meeting was that he was ill.

　2. I don't believe the reason (that/which) he gave me. （作宾语）

　3. Have you asked him the reason that may explain his success? （作主语）

　当先行词为way时，the way在从句中作状语时，定语从句常用that, in which,或how引导，that常可以省略。

　the way在从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 way （that/which）I have shown you.

　 Ⅳ. 限制性定语从句与非限制性定语从句的区别：

　1. 形式上，非限制性定语从句往往用逗号隔开。

　2. 语法上，非限制性定语从句一般不用that.

　3. 语义上，限制性定语从句与先行词关系紧密，起限定作用，如果去掉了这个定语从句，整个句子就不完整或者会改变意思；而非限制性定语从句与先行词关系不是很紧密，对先行词起补充说明或描述的作用。

　This is the book I like best. 这就是我最喜欢的那本书。

　Beijing, which has been China's capital for more than 800 years, is rich in cultural and historic relics. 北京是中国八百年之久的古都，它有着丰富的文化和历史遗产。

　4. 翻译时，限制性定语从句可译为一句（较短的一般译为"的"字结构）；而非限制性定语从句可译为两句。（见上句翻译）

　比较: He has a sister, who is a musician.

　He has a sister who is a musician.

　引导非限制性定语从句的关系代词，指人时用who, whom, whose , 指物时用which , whose; 关系副词when，where, why, etc.

　1. He studied hard at school when he was young, which leads to his success in his later life.

　2. Tom's father, who arrived just now, is a famous scientist.

　 Ⅴ. 几个易混淆的关系代词的比较:

　●that & which:

　在定语从句中，which 和that 在指代事物时，一般可以互换使用，但并非在任何情况下都是这样，这里介绍宜用that, 而不宜用which 的情况.

　①先行词为不定代词,all, much, something, everything, anything, nothing, none, the one等,

　1.We should do all that is useful to the people .

　2.There's nothing that can be said about it .

　3.Do you mean the one that was bought yesterday?

　②先行词被only, any, few, little, no, just, very, one of等词修饰时。

　1.The only thing that we could do was to wait.

　2.That's the very word that is wrongly used.

　3. The last place (that) we visited was the chemical works.

　比较 *This is one of the best novels that were published last year.

　This is the only one of the best novels that was published last year.

　③先行词是序数词时或被序数词修饰时。

　1.When we talk about Wuxi, the first that comes into mind is Tai Lake.

　2.This is the third film that has been shown in our school this term.

　④先行词是最高级或被最高级修饰时。

　1.This is the best that can be done now.

　2.The most important thing that should be done right now is how to stop him from going on.

　⑤先行词既有人又有物，用which和who都不适合，这时宜用that.

　1.The writer and his novel that you have just talked about is really well known .

　2.The rider and his bike that had run over an old woman were held up by the police.

　⑥被修饰词为数词时.

　1.Yesterday I caught two fish and put them in a basin of water .Now you can see the two that are still alive .

　⑦如果有两个从句，其中一个关系代词已用which ,另一个关系代词宜用that，以避免语言的单调或重复。

　Edison built up a factory which produced things that had never been seen before.

　⑧疑问词是who或which，关系代词宜用that，以避免重复。

　1. Which is the book that you like best?

　2. Who is the man that is standing at the gate?

　⑨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.

　⑩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 .

　1. That's a good book that will help you a lot.

　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.Is this the room in which Mr. White lives?

　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 popular in our country. (which指代主句)

　③在一个句子中有两个定语从句，其中一个定语从句的关系代词用了that, 另一个宜用which .

　1. Let me show you the novel that I borrowed from the library which was newly open to us.

　④当关系代词后面带有插入语时.

　1. Here's the English grammar which, as I have told you, will help improve your English.

　⑤先行词本身是that, 宜用which .

　What's that which she is looking at?

　⑥先行词是those+复数名词.

　A shop should keep a stock of those goods which sell best.

　●who & that:

　who 和 that 指代人时，有些情况宜用who, 而不宜用that

　①先行词为anyone, anybody, those, all, one, ones, they, he, people时. 如：

　1.The person I want to learn from is the one who studies hard and works well.

　2.Anyone who (=Whoever) failed to come to the meeting yesterday must give his reason .

　3.Those who are not fit for their work should leave office at once.

　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 .

　2.There are several students in our class who are still not sure about the use of attributive clauses.

　③当先行词有较长的后置定语时. 如：

　1. I met a foreigner in the park yesterday afternoon who could speak Chinese very well.

　●as & which:

　as & which 引导非限制性定语从句的区别：

　①位置的不同：

　which 引导的定语从句只置于所限制的句子后；as 位置较灵活，也就是说as可置于所限制的句子前面；插在句子中或放在句子后。如：

　1. He was late again, which made his teacher very angry.

　2. Jack, as you know, is an honest man. 或Jack is an honest man , as you know.

　或As you know, Jack is an honest man.

　②先行词的不同：

　as引导非限制性定语从句时，其先行词多为一个句子；

　which引导非限制性定语从句时，其先行词可以是一个词，一个短语或一个句子。

　1. She was very patient towards the children, which her husband seldom was.

　2. He was proud, which I dislike very much.（先行词是一个句子）

　3. He is an honest man, as is known to all.

　③as 一般译为"正如""就像"，"这一点"

　as we all know；as you know; as is known to all; as you see; as we can see; as has been expected; as we have imagined.

　高中英语定语从句句型总结

　一、疑问句中考查定语从句

　1. Is this the farm ________ you visited last week？

　A. whereB. the oneC. on whichD. /

　解析答案是D。命题人经常利用疑问句的特殊结构来干扰学生的正确选择。遇到这类定语从句时，最好的办法是先把疑问句还原成陈述句，然后判断谁是先行词，再看关系词在定语从句中所充当的成分，最后确定正确答案。

　二、倒装句中考查定语从句

　2. We came to a place， ________ stood a big tower.

　A. whichB. thatC. /D. where

　解析正确答案是D。为了保持句子平衡，句子用了倒装语序。倒装的使用使定语从句的结构变得较为特殊，因此对于使用倒装语序的定语从句，应先把倒装语序还原成正常语序，这样句子结构就比较清晰了。

　三、 拆分词组和固定搭配

　3. The second is connected with the use ________ the body makes of food.

　A. of whichB. whereC. to doD. that

　4. Why can’t you realize the part ________ they have played in our life？

　A. whichB. on whichC. whenD. where

　解析正确答案分别是D和A。一些词组和搭配被拆开后，句子的含义就变得难以理解。首先把拆开的词组复原是理解此类定语从句的关键。上述句子中包含以下词组：make use of， play a part (in)。

　四、添加插入语或状语

　5. The scientist has made another discovery， _______ I believe is of great importance.

　A. thatB. /C. whichD. why

　解析应选择C。这类句子主要利用插入语或状语的添加来增加试题的难度。常见的插入语有：I think (suppose， expect， believe， imagine)， in my opinion， to tell you the truth等。做这类题目时，最佳的办法是先删去插入语或状语，这样句子的主干部分就一目了然了。

　五、插入非谓语动词

　6. Is this the man ________ you want to have ________

　the radio for me？

　A. who；repairedB. that；repaired

　C. whom；repairingD. that；repair

　解析D项正确。非谓语动词是英语中难度较大的语法项目之一，因而在定语从句中加入非谓语动词就成了学生最易失分的题目。对付这类题目最有效的办法就是将句子还原。如：我们可以把几个句子中的定语从句进行还原，还原后的句子应是：You want to have the man repair the radio for me.

定义

I. 定语从句起形容词的作用，在句中修饰一个名词或代词。被修饰的词叫做先行词，引导定语从句的词叫关系词，他的作用一是放在先行词与定语从句中间起了连接作用，二是在从句中担当一个成分，并与先行词保持数的一致。

关系词 先行词 从句

成分 例句 备注

关系代词 who 人 主语 Do you know the man who is talking with your mother? whom, which和that在从句中做宾语时，常可以省略，但介词提前时后面关系代词不能省略，也不可以用that

whom 人 宾语 Mr. Smith is the person with whom I am working

The boy (whom) she loved died in the war..

whose 人，物 定语 I like those books whose topics are about history.

The boy whose father works abroad is my desk mate.

that 人，物 主语

宾语 A plane is a machine that can fly.

She is the pop star (that) I want to see very much.

which 物 主语

宾语 The book (which) I gave you was worth $10.

The picture which was about the accident was terrible.

as 人，物 主语

宾语 He is such a person as is respected by all of us.

This is the same pen as I lost yesterday. as做宾语一般不省略

关系副词 when 时间 时间

状语 I will never forget the day when we met there. 可用on which

where 地点 地点

状语 This is the house where I was born. 可用in which

why 原因 原因

状语 I can’t imagine the reason why he turned down my offer. 可用for which

Ⅱ. as与which的区别：

定语

从句 区别 例句

限制性定语从句　中 名词前有such和the same修饰时，关系代词用as,不能用which He is not such a fool as he looks.

Don’t read such books as you can’t understand.

非限制性定语从句中 as和which都可以指代前面整个主句。如果有“正如，象”的含义，并可以放在主句前，也可以放在后面，那么用as；而which引导的从句只能放主句后，并无“正如”的意思。 They won the game, as we had expected.

They won the game, which we hadn’t expected.

As is well known, he is a famous film star in the 1980s.

Ⅲ. 限制性定语从句与非限制性定语从句的区别：

类别 语法意义及特征 例句

限制性定语从句 对先行词起修饰限制作用，如果去掉，主句意思就不完整明确，这种从句与主句的关系十分密切，写时不用逗号分开。 The accident happened at the time when I left.

非限制性定语从句　 对先行词作附加的说明，与主句的关系不十分密切，较松散。从句和主句之间用逗号分开，相当于一个插入语，不能用that引导，关系代词做宾语时也不能省略。 His mother, whom he loved deeply, died ten years ago.

一、考点聚焦

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 ?

7、宜用which而不用that的情况

（1）在非限制性定语从句中

（2）在关系词前有介词时

（3）当先行词本身是that时

（4）当关系词离先行词较远时

8、关系词who与that指人时，也有不同情况分别用不同的关系词

（1）当主句是there be句型时，关系词用who。

（2）先行词是为anyone、those、someone、everyone、one等词时，关系词用who。

（3）当主句是who作疑问词时，关系词用that。

Who is that girl that is standing by the window?

（4）whom在从句中只作宾语，可被who取代。

9、whose作关系词既指人又指物，在从句中作定语。如：

Do you know Mr. Smith whose story is very moving?

There is a room, whose window faces the river.

There is a room, the window of which faces the river.

10、关系代词as,在从句中作主语、宾语和表语。

（1）先行词被such和the same修饰，或句型as many（much）中，从句都用as 引导。

Such books as you bought are useful. The school is just the same as it was 10 years age.

注意：区别①such … that … 引导的结果状语从句。They are such　lovely children that we love them much　.②the same … that … 引导定语从句。I want to use the same tool that you used just now.

（2）无先行词的定语从句用as和which引导。

区别：①意义上：as 含有“这点正如……一样”。②位置上：as 从句可置句首，也可在另处。

He didn’t pass the exam, as we had expected.

There is lots of air in loose snow, which can keep the cold out.

As is known, the earth is round, not flat.

11、关系副词when与where、why、that

when 指时间 = in / at / on / during which

where指地点 = in / at / from / which

why指原因 = for which

当先行词为way、day、reason、time时，可用that作关系副词。（非正式场合）

I don’t like the way that / in which / he talks.

当time作先行词时，关系词可以省掉。

This is the first time I have given you a lesson in French.

12、必须注意的问题

（1）关系词作主语时，从句中谓语的数。

（2）注意区别定语从句与强调句。

①定语从句中关系词作从句成分，复合句。

②强调it无意义，that / who不是引导词。

③强调it is / was和that / who后如果句子意思讲得通则是强调句，讲不通则不是。

It is the museum that / which we visited last year.(定语从句)

It was in the hotel that we stayed last night.（强调句）

（3）定语从句与同位语从句的区别。

①定语从句引导词被称为关系词，that充当主语、宾语、表语。有时可省略。

②同位语从句引导词被叫做连词，that不能充当任何成分，不可省。

Word came that their army was defeated.(同位语)

We expressed to them our wish that was the same as their.(定语)

（4）关系词在从句中省略的情况。

①关系词作宾语，前无介词时。

②关系词作表语。

（5）限制性定语从句与非限制性定语从句的翻译。

（6）关系词前有介词或复杂介词，关系词只能是which和whom。

（7）几个特殊的定语从句句型：

①He is the only one of the students who has got very good marks in the match.（句中one为先行词）

He is one of the students who have got good marks in the match.（句中students为先行词）

②Is this place the one (that) we visited yesterday？ Is this the place (that / which) we visited yesterday?

③He stood at the window, from where he could see what was happening.

④It may rain, in which case the match will be put off.

二、精典名题导解

1. The film brought the hours back to me _________ I was taken good care of in that faraway village.（NMET 2001）

A. until B. that C. when D. where

解析：答案为C。本题考查分隔定语从句的关系词的选择。作好本题的关键是要能辨认出该定语从句的先行词the hours和关系词被介词短语to me所分隔。定语从句的先行词是表时间的名词hours, 并且关系词在从句中用作状语，故应选择表示时间的关系副词when。

2. ___________ is known to everybody, the noon travels around the earth once every month.(NMET 2001)

A. It B. As C. That D. What

解析：答案为B。本题考查as引导的非限制定语从句。as作“正如……”解时，引导的非限制性定语从句来修饰整个句子。当as在从句中作主语时，常用于下列短语：as is known、as is said、as is reported、as is announced等。要注意掌握作关系代词引导定语从句的用法。

3. After living in Pairs for fifty years he returned to the small town ___________ he grew up as a child.(NMET 1996)

A. which B. where C. that D. when

解析：答案为B。本题考查限制性定语从句中关系词的选择。定语从句的先行词是表示地点的名词短语the small town, 且关系词不作定语从句中的主语和宾语而作地点状语，因此定语从句必须用关系副词where引导。要注意分清先行词在从句中充当的成分，然后选择适当的关系词。
