定语从句
定语从句
定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个成分,定语从句分为限定性和非限定性从句两种。
状语从句分为时间状语从句,结果状语从句,让步状语从句,原因状语从句,条件状语从句以及行为方式状语从句。
名词从句包括主语从句,宾语从句,表语从句和同位语从句及therebe句型。
一、限定性定语从句
1.that即可代表事物也可代表人,which代表事物;它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略。
而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置
2.which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢
3.代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all,anything,much等,这时的that常被省略
4.who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语
5.where是关系副词,用来表示地点的定语从句
6.when引导定语从句表示时间
〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导
BythetimeyouarriveinLondon,wewillhavestayedtherefortwoweeks.
IstillrememberthefirsttimeImether.
Eachtimehegoestobusinesstrip,hebringsalotoflivingnecessities,suchastowers,soap,toothbrushetc.
7.whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格
8.当从句的逻辑主语是some,any,no,somebody,anybody,nobody,something,anything,everything或nothing时,常用thereis来引导
二、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
2.在引导限定性定语从句时,that有时相当于inwhich,atwhich,forwhich或atwhich
Attitudestowardsdaydreamingarechanginginmuchthesamewaythat(inwhich)attitudestowardsnightdreaminghavechanged.人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处。
Ilikethemusicfortheveryreasonthat(forwhich)hedislikeit.我出于某种原因喜欢这种音乐,而他恰恰与我相反。
Wearrivedthedaythat(onwhich)theyleft.刚好我们到的那天他们走了。
3.有时as也可用作关系代词
4.在非限定性定语从句中,不能用that,而用who,whom代表人,用which代表事物.
三.定语从句及相关术语
1.定语从句:
修饰一个名词或代词的从句称为定语从句,一般紧跟在它所修饰的先行词后面。
2.关系词:
引导定语从句的关联词成为关系词
关系词有关系代词和关系副词。
关系代词有that,which,who,whom,whose,as等;关系副词有where,when,why等。
关系词常有3个作用:
1,引导定语从句。
2,代替先行词。
3,在定语从句中担当一个成分。
四.关系代词引导的定语从句
1.who指人,在从句中做主语
(1)TheboyswhoareplayingfootballarefromClassOne.
(2)YesterdayIhelpedanoldmanwholosthisway.
2.whom指人,在定语从句中充当宾语,常可省略。
(1)Mr.Liuistheperson(whom)youtalkedaboutonthebus.
(2)Mr.LingisjusttheboywhomIwanttosee.
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)Themanwho/whomyoumetjustnowismyfriend.
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.
(2)Thisisthepen(which)heboughtyesterday.
4.that指人时,相当于who或者whom;指物时,相当于which。
在宾语从句中做主语或者宾语,做宾语时可省略。
(5)Thenumberofthepeoplethat/whocometovisitthecityeachyearrisesonemillion.
(6)Whereisthemanthat/whomIsawthismorning?
5.whose通常指人,也可指物,在定语从句中做定语
(1)Hehasafriendwhosefatherisadoctor.
(2)Ioncelivedinahousewhoseroofhasfallenin.
whose指物时,常用以下结构来代替
(3)Theclassroomwhosedoorisbrokenwillsoonberepaired.
(4)Theclassroomthedoorofwhichisbrokenwillsoonberepaired.
(5)Doyoulikethebookwhosecoverisyellow?
(6)Doyoulikethebookthecolorofwhichisyellow?
五.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等
(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)Themanwho/thatyoutalkedwithismyfriend.(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
(1)Helovedhisparentsdeeply,bothofwhomareverykindtohim.
(2)Inthebaskettherearequitemanyapples,someofwhichhavegonebad.
(3)Therearefortystudentsinourclassinall,mostofwhomarefrombigcities.
六.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.
(2)ThehousewhereIlivedtenyearsagohasbeenpulleddown.
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
(1)Thereasonwhy/forwhichherefusedtheinvitationisnotclear,
(2)Fromtheyearwhen/inwhichhewasgoingtoschoolhebegantoknowwhathewantedwhenhegrewup.
(3)Greatchangeshavetakenplaceinthecityinwhich./whereIwasborn.
七.限制性定语从句和非限制性定语从句
限制性定语从句非限制性定语从句
形式上不用逗号和主句隔开用逗号和主句隔开
意义上是先行词不可缺少的定语,不能删除是对先行词的补充说明,删除后意思仍完整
译法上翻译成先行词的定语,“…的…”通常翻译成主句的并列句
关系词的使用上A.做宾语时可省略B。
可用that
C.可用who代替whomA.不可省B。
不用that
C。
不用who代替whom
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修饰时
(1)ThisisthebestfilmthatIhaveseen.
4.当形容词被thevery,theonly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?
(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
(1)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.同位语
(2)Theideawasthatwecouldasktheteacherforadvice.
(3)Thefactthattheearthmovesaroundtheearthisknowntoall.
(4)Thefactisthattheearthmovesaroundtheearth.
