关系代词有that,which,who,whom,whose,as等;

二.关系代词引导的定语从句

1.who指人,在从句中做主语

注意:

关系代词whom在口语和非正式语体中常用who代替,可省略。

3.which指物,在定语从句中做主语或者宾语,做宾语时可省略

(1)Footballisagamewhichislikedbymostboys.

5.whose通常指人,也可指物,在定语从句中做定语

(5)Doyoulikethebookwhosecoverisyellow?

(6)Doyoulikethebookthecolorofwhichisyellow?

三.介词+关系代词引导的定语从句

关系代词在定语从句中做介词宾语时,从句常由介词+关系代词引导

(1)Theschool(that/which)heoncestudiedinisveryfamous.

(2)Theschoolinwhichheoncestudiedisveryfamous.

(3)TomorrowIwillbringhereamagazine(that/which)youaskedfor.

(4)TomorrowIwillbringhereamagazineforwhichyouasked.

(5)We”llgotohearthefamoussinger(whom/that/who)wehaveoftentalkedabout.

(6)We”llgotohearthefamoussingeraboutwhomwehaveoftentalked.

注意:

1.含有介词的动词短语一般不拆开使用,如:

lookfor,lookafter,takecareof

(1)Thisisthewatchwhich/thatIamlookingfor.(T)

(2)ThisisthewatchforwhichIamlooking.(F)

2.若介词放在关系代词前,关系代词指人时用whom,不可用who或者that;指物时用which,不能用that;关系代词是所有格时用whose

(1)Themanwithwhomyoutalkedismyfriend.(T)

(2)Themanwithwho/thatyoutalkedismyfriend.(F)

(3)TheplaneinwhichweflewtoCanadaisverycomfortable.(T)

(4)TheplaneinthatweflewintoCanadaisverycomfortable.(F)

3.“介词+关系代词”前可有some,any,none,both,all,neither,most,each,few等代词或者数词

(2)Inthebaskettherearequitemanyapples,someofwhichhavegonebad.

(3)Therearefortystudentsinourclassinall,mostofwhomarefrombigcities.

四.关系副词引导的定语从句

1.when指时间,在定语从句中做时间状语

(1)IstillrememberthedaywhenIfirstcametotheschool.

(2)Thetimewhenwegottogetherfinallycame.

2.where指地点,在定语从句中做地点状语

(1)ShanghaiisthecitywhereIwasborn.

3.why指原因,在定语从句中做原因状语

(1)Pleasetellmethereasonwhyyoumissedtheplane.

(2)Idon”tknowthereasonwhyhelooksunhappytoday.

注意:

关系副词引导的从句可以由“介词+关系代词”引导的从句替换

(2)Fromtheyearwhen/inwhichhewasgoingtoschoolhebegantoknowwhathewantedwhenhegrewup.

(3)Greatchangeshavetakenplaceinthecityinwhich/whereIwasborn.

五.限制性定语从句和非限制性定语从句

限制性定语从句举例:

(1)TheteachertoldmethatTomwastheonlypersonthatIcoulddependon.

(2)Chinaisacountrywhichhasalonghistory.

非限制性定语从句举例:

(1)Hismother,wholoveshimverymuch,isstrictwithhim.

(2)China,whichwasfoundedin1949,isbecomingmoreandmorepowerful.

要注意区分以下几个句子的不同

(1)Hisbrotherwhoisnowadoctoralwaysencourageshimtogotocollege.

他那当医生的哥哥常鼓励他要考上大学。

(他还有其他的哥哥)

(2)Hisbrother,whoisnowadoctor,alwaysencourageshimtogotocollege.

他的哥哥是当医生的,常鼓励他要考上大学。

(他只有一个哥哥)

难点分析

(一)限制性定语从句只能用that的几种情况

1.当先行词是anything,everything,nothing(something除外),few,all,none,little,some等代词时,或者是由every,any,all,some,no,little,few,much等修饰时

(1)HaveyoutakendowneverythingthatMr.Lihassaid?

(2)Thereseemstobenothingthatseemsimpossibleforhimintheworld.

(3)Allthatcanbedonehasbeendone.

(4)ThereislittlethatIcandoforyou.

注意:

当先行词指人时,偶尔也可以用who

(4)Anymanthat/.whohasasenseofdutywon”tdosuchathing.

2.当先行词被序数词修饰

(1)ThefirstplacethattheyvisitedinLondonwastheBigBen.

3.当先行词被形容词最高级或比较级修饰时

(1)ThisisthebestfilmthatIhaveseen.

4.当先行词被very,only修饰时

(1)ThisistheverydictionarythatIwanttobuy,

(2)Afterthefireinhishouse,theoldcaristheonlythingthatheowned.

当先行词指人时,偶尔也可以用who

(3)WangHuaistheonlypersoninourschoolwhowillattendthemeeting/

5.当先行词前面有who,which等疑问代词时

(1)Whoisthemanthatisstandingthere?

(2)WhichistheT-shirtthatfitsmemost?

6.当先行词既有人,也有动物或者物体时

(1)Canyourememberthescientistandhistheorythatwehavelearned?

只用which,whom

1..当先行词有限定性修饰词时

whatwasthenameofthewarintheUSAwhichlasted5years?

2.当先行词是one,ones,anyone,等时用who;those做先行词时,指人用who,指物用whichThosewhowanttogototheGreatWallsignuphere.

HewhohasneverbeentotheGreatWallisnotatrueman.

3.介词+which,whom

(二)关系代词as和which引导的定语从句

as和which引导非限制性定语从句,有相同之处也有不同之处。

具体情况是:

1.As和which都可以在定语从句中做主语或者宾语,代表前面整个句子。

(1)Hemarriedher,as/whichwasnatural

(2)Hewashonest,as/whichwecansee.

2.as引导非限制性定语从句,可放在主句之前,或者主句之后,甚至可以切割一个主句;which引导的非限制性定语从句只能放在主句之后。

另外,as有“正如……,正像……”的意思

(1)Asisknowntoall,Chinaisadevelopingcountry.

(2)Heisfromthesouth,aswecanseefromhisaccent.

(3)John,asyouknow,isafamouswriter.

(4)HehasbeentoParismorethanseveraltimes,whichIdon”tbelieve.

注意:

当主句和从句存在逻辑上的因果关系时,常用which

(5)Tomwasalwayslateforschool,whichmadehisteacherangry.

3.当先行次受such,thesame修饰时,常用as

(1)Ihaveneverheardsuchastoryashetells.

(2)Heisnotsuchafoolashelooks.

(3)ThisisthesamebookasIlostlastweek.

注意:

当先行次由thesame修饰时,偶尔也用that引导定语从句,但是和由as所引导的定语从句意思不同

(4)SheworethesamedressthatsheworeatMary”swedding.

她穿着她在Mary婚礼上穿过的一条裙子。

(5)Sheworethesamedressasheryoungsisterwore.

她穿着和她妹妹所穿的一样的裙子。

(三)以theway为先行词的定语从句通常由inwhich,that引导,而且通常可以省略。

(1)Thewayinwhich/that/./heansweredthequestionwassurprising.

(四)but有时也可以做关系词引导定语从句

but可被看作关系代词,引导定语从句,在从句中作主语,意义上相当于whonot或thatnot,即用在否定词或具有否定意义的词后,构成双重否定。

如:

1)Thereisnomotherbutlovesherchildren.没有不爱自己孩子的母亲。

2)Therewasnoonepresentbutknewthestoryalready.在场的人都知道这个故事。

(3)Thereareveryfewbutunderstandhisidea.(but=whodon”t)

(五)区分定语从句和同位语从句

1.定语从句修饰先行词,它和先行词是修饰关系;同位语从句说明先行词的具体内容,是补充说明的关系

(1)TheplanethathasjusttakenoffisforLondon.定语从句

(2)Thefactthathehasbeendeadisclear.同位于从句

2.定语从句由关系代词或者关系副词引导,关系词在句中充当成分,有时可以省略;同位语从句主要由that引导,在句中一般不做成分;句子也可以由when,where,how,why,whether,what等词引导,充当成分

(1)Thenewshetoldmeistrue.

(2)Thenewsthathehasjustdiedistrue.

3)Theproblemthatwearefacingnowishowwecancollectsomuchmoney.定语

(4)Theproblemhowwecancollectsomuchmoneyisdifficulttosolve.

3.同位语从句和先行词一般可以用be动词发展成一个完整的句子,而定语从句不可以

(1)Theideathatwecouldasktheteacherforadviceiswonderful.

(2)Theideawasthatwecouldasktheteacherforadvice.

(3)Thefactthattheearthmovesaroundtheearthisknowntoall.同位语
