  非限制性定语从句 

 非限定性定语从句:非限定性定语从句的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

    1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分 that不能用于引导非限制性定语从句

    例如:

    Her house,which was built a hundred years ago,stood still in the earthquake.(那座房子在地震中依然耸立,它是一百多年前建造的。)

    3. 有时as也可用作关系代词

    4. 在非限定性定语从句中,用who, whom代表人,用which代表事物.

    5.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。

    6.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。

非限制性定语从句只是对主句内容,或先行词的补充、解释或附加说明。主句与先行词或从句之间一般用逗号分开,常常单独翻译。没有它,主句意思仍然完整。引导非限制性定语从句的关系代词有aswhichwho whomwhose等,作定语从句的主语、宾语、表语及定语。关系副词whenwhere等,作定语从句的状语。关系代词和关系副词在定语从句中一般不能省。

    一、as引导非限制性定语从句时,可以代主句的全部或部分内容。常表说话人关于说话的依据、态度、评论、看法等。有正如、像等意思。定语从句可以置主句句首、句中或句末。as后常接expectknowreportsaysee等动词的主、被动语态句。

    1 ____is known to everybodythe moon travels round the earth once every month

    AIt BAs CThat DWhat

    2Mikeas we expectedattended the meeting.像我们所期望的那样,迈克参加了会议。

    3He wasn't unconsiciousas could be judged from his eyes.他并未失去知觉,这从他的眼神可以判断出来。

    二、which引导非限制性定语从句的情况很多。

    I.指代主句的全部或部分内容时,常表事实、状态、起因等,有这就使得、这一点等意思,常置主句末。主句与定语从句用逗号分开。

    1Dorathy was always speaking highly of her role in the play,,of coursemadethe others unhappy

    Awho Bwhich Cthis Dwhat

    II.指代先行词有多种情况。定语从句置先行词后面。

    1.在“n./pron./num....+prep.+ which”“prep.+which”定语从句里。

1They talked about a moviethe name of which I've never forgotten.他们谈论过一部电影,我决不会忘记片名。

  2In Sydney the Chinese team got 28 gold medals165 of which were won by women.在悉尼奥运会,中国队夺得了28枚金牌,其中165枚是女子夺得的。

    4Chaplin went to the states in 1910by which time he had learnt to dance and act in comedies.卓别林1910年去了美国,那时他已学会跳舞和演喜剧了。

    2.表唯一性,或者就是指代先行词的事物时。

    The damwhich is the biggest in the worldis 3830 metres long.大坝长3830米,是世界上最大的坝。

    3.先行词是独一无二的事物时。

    4.先行词表示类属的事物时。

    5.先行词是专有名词时。

    1Three of the biggest man-made projects in the world are the Great Wall of Chinathe Pyramids of Egypt and the Aswan High Dam which is also in Egypt.世界上最大的三项人造工程是中国的长城,埃及的金字塔和阿斯旺高坝,它也在埃及。

    2The Nilewhich used to flood every yearnow runs more regularly below the dam.尼罗河年年涨洪水,现在比较正常地在大坝下面流过了。

    6.先行词是表人的职业、品质、身份等名词,作定语从句的表语时。主句和定语从句之间含有对比的意思。

    Mike's brother is a policemanwhich he isn't.迈克的哥哥是警察,他可不是。

    7.先行词是形容词作定语从句的表语时。主句和定语从句含有对比的意思。

    三、aswhich是指代主句内容的非限制性定语从句时,表依据、评论与表事实、状态等没有多大差别,又在主句末时,有时可以通用。

    1He is quite pleasedas which can be seen from his face.他非常高兴,从他的表情可以看出来。

    2You always work hardas which everyone knows.大家都知道,你一向勤奋学习。

    4Bamboo is hollowwhich makes it very light.竹子是空的,这就使得它很轻。 在否定意义的非限制性定语从句里,一般用which引导。

    四、whowhomwhose等引导非限制性定语从句时,指代人的普通名词、专有名词等。表示正是或专指先行词等情况。在定语从句中作主语、宾语、定语等。

1 基本区别

  根据定语从句与先行词的关系,可将定语从句分为限制性定语从句和非限制性定语从句。一般说来,限制性定语从句是整个句子不可缺少的部分,如果省略会影响全句的主要思想,这种定语从句前面一般不用逗号;而非限制性定语从句则只是主句的一种补充说明,即即使去掉,也不会影响全句的主要思想,这种定语从句前通常有逗号隔开。如:

  This is the book that you want 这就是你要的那本书。

  句中的you want为限制性定语从句,如果去掉,意思就不清楚。

  He bought me a book which was very useful 他给我买了一本书,非常有用。

  句中的which was very useful为非限制性定语从句,如果去掉,句子意思仍是清楚的。

  2 关系词的区别

  关系代词that和关系副词why通常只用于引导限制性定语从句,不用于引导非限制性定语从句。如:

  她收到了老板的邀请,这是她意想不到的。

  误:She received an invitation from her boss that came as a surprise

  正:She received an invitation from her boss which came as a surprise

  他失去工作的主要原因是他喝酒。

  误:The main reason why he lost his job was that he drank

  正:The main reason why he lost his job was that he drank

  另外,在限制性定语从句中,关系代词which用作宾语时,如果不是紧跟在介词之后,通常可以省略;但在非限制性定语从句中,不管在什么情况下均不可省略关系代词which

  3 用法注意

  当一个名词已由其他词语作了完整的表述,这个名词后则不宜再用限制限制性从句,而应改用非限制性定语从句。如:

  我去看买的房子有一个很漂亮的花园。

  误:My house which I bought last year has got a lovely garden

  正:My house which I bought last year has got a lovely garden

  若要用限制性定语从句,则应将物主代词my改为the,即说成:

  The house which I bought last year has got a lovely garden

  4 补充说明

  非限制性定语从句有时形式上是从句,实质上其功用相当于一个并列的分句。如:

  He said he had no money which was not true 他说他没有钱,这不是实话。(which相当于but it

  Then he met Mary who invited him to a party 后来他遇到玛丽,玛丽邀请他去参加晚会。(who相当于and she

  My father may have to go into hospital in which case won’t be going on holiday 我父亲可能需要住院,如果那样他就不去度假了。(in which case相当于and in that case

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。(whichdrive 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thatwhy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。
