限制性定语从句与非限制性定语从句的区别

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:

Thisistheverypersonthatiswantedbythepolic.e

Heisthemanwho/thatlivesnextdoo.r

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:

Hewillnotbeabletospendtheholidaywithhisfamily,whichisabig

annoyancetohim.

Theminister,whoistovisitouruniversity,issaidtobeaQinghuaUniversitygraduate.

Thebook,whichyoursisterboughtyouinXinhuaBookstore,isveryufulinimprovingyourspokenEnglish.

Thebusinessman,whosuitcahasbeenfoundbyastrang,ehrasleftforBeijing.

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:

TheThames,whichisnowcleanenoughtoswimi,nwaspollutedforoverahundredyears.

Mymother,whohasbeenonavisittoAustral,iawillflybacktomorrow.

Allofthebooks,whichhavebeendonatedbyvisitingprofess,oarsretobeudbythechildreninHopeSchool.

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:

Theysayheplaystruant,whichhedoesn'.[w

t

hich指代playstruant]

Themeetingwasputofftillnextmonth,asweh构建近义词 oped.[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:表一:限制性定语从句与非限制性

定语从句的区别

限制性定语从句

非限制性定语从句

1

1.提供确定或限定主句中某个名词的信息。

付号(逗号/插入语/破折号)。

4.不可以修饰整个命题,只修饰一个名!

词。

5.可使用that和who(m),which等关系代

!词。

6.不常用来修饰专有名词。

息。

2.由两个独立的深层嵌入句派生而来。

3.书面语中用逗号,口语中用特殊的停顿和降

低声调来把定语从句和主句分隔开来。

4.可以修饰一个中心名词,或以评价的形式修

饰整个命题。

不能当作关系代词,只可用

!词。

3.2定语从句中的关系代词

3.2.1关系代词that,which,who在定语从句中做主语

在限制性定语从句中,who或that用于指人,that或which用于指物,它们在

定语从句中代替名词性主语或代词性主语,不能省略。例如:

Heisthemanwho/thatliveshere[不能说:>Heisthemanwhoheliveshere.]

Thebagwhich/thathasbeenputthereforalongtimbelongstoWang

Hong.

3.2.2who(m),which,that在定语从句中作宾语

表示人的时候用who(m)或that,它们在从句中代替名词性宾语或宾格代词,作

定语从句宾语的whom/that通常可以省略,在口语中常用who代替whom。例如:

He'sthema又一个新的开始 whom/thatImet.

TherearesomepeopleherwhoIwantyoutomeet.

表示动物和东西的时候应用which/that:

Thepiecesofmusic(that)hehascompodaresungbymanypopsin

gers.

Taxesconsistofmoneythat)peoplepaytosupporttheirgovernment

2

They'rethepostcardwshichIntfromAmerica.

3.2.3who(m),which或that作介词的宾语,关系代词可省略。

定语从句的介词的位置非常重要,我们可以说:

Heisthepersontowhomlwrote.[非常正式用法](但不可以说:>to

who).

或:Heisthepersonwho(m)lwroteto./Heistheperson(whom)Iwroteto.

Thisisthepaninwhichlboiledthemilk.[非常正式用法]

或:Thisisthepanwhichlboiledthemilkin./Thisisthepan(that/which)Iboiledthemilkin.

3.2.4who+名词

关系代词who是既可用于限制性定语从句,也可用于非限制性定语从句,在

从句中作定语,一般用来指人,代替所有格形容词(my,his,your,her,its等),在从

句中当定语,没有阴性、阳性或单数、复数的变化;有时也可指物,指物时可以用

ofwhich代替。例如:

ms.

Thebicyclewhobrakewasdamagedhasnowbeenrepaired.=The

bicycle,thebrakeofwhichwasdamage,isa

greatinventorwhofameisworld-wide.

3.2.5that的用法

1、that只用于限制性定语从句,既可指人,又可指物,在句中用做主语或宾语。

(见

2、当先行词是all,much,little,theone,anything,something,nothing,

everything,none等不定代词时,关系代词只用that。例如:

That'sallthatlknewaboutit.

Isthereanythingthatlcandoforyou?

Haveyoudoneeverythingthatisassignedtoyo?u我不在乎的英文

3、先行词被形容词最高级以及first,last,any,only,few,much,no,some,very

等词修饰时,关系代词只用that。例如:

Itisthemostinterestingfilmthatl'veverread.

3

Thebestthingthathecoulddoatprenttoleave.

Thisisthefirsttimethathehasbeenthere

Sheistheonlyonethathasfinishedhertaskontime

Attheverybeginning,wehavejusttoomuchworkthatneedstobedone

4、在therebe句型中,只用that,不用which。例如:

TherearesomepeoplethatI'dliketointroducetoyou

5、先行词既有人,又有物时,用that

o

例如:

Avictimisaperson,animalorthingthatsufferspain,death,harm,etc

Themanandhisdogthatwerenappingoutsidetheroomwerephotographedbythejournalist.

6、在“Itis+名词+定语从句

1

+定语从句

2”

的强调结构中,从句

2

要用that

o

如:

Itisalwaysthemouthwhichtalkstoomuchthatincurstroubles(言多必

失。)

Itisonlyamanwhoisquiteexperiencedthatcanfulfillthistask

3.2.6which的用法

1、which一般只用于指物⑻,有时也用来指性别不明的婴儿

b)

o

例如:

a:Thetileswhichfellofftheroofcaudriousdamage.

b:ThebabywhichthenurhasjustbroughtiinJohn'schild.

2、如果指物的关系代词紧跟在介词后面,只能用which,不能用that。例如:

Thisisthehouinwhichshespentherchildhood.

Theagencyfromwhichweboughtourticketsbankrupt.

3、引导非限制性定语从句时,用来指物替代名词词组。例如:

Thisbook,whichhasonlybeenreview^waspublishedayearago.

4、替代整个句子或句子的一部分:

ThemeetinghasbeenputofftillnextFriday,whichisgoodnewstothem

(指代整个主句

Shesaidthathersonwouldbecomeascientistwhichwethoughtpossible.

(指代that分句

Sheisveryattentiveinclasswhichherarelyis.(指代整个短语)

4

3.2.7as的用法

5

1、as引导限制性定语从句时,常与such或thesame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:

ooksasthere

wereontheshelifnterestedus.

Ihavegotintothesametroubleashe(has).

试比较thesame…a和口thesame…tha

t

Thisisthesamebookaslreadlastweek(这和我上周读的那本书是一样

的。)

Thisisthesamebookthatlreadlastyear.(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:

Shetoldmethesamestoryas/thatshehadtoldyo.u

Ihadthesamedifficultythat/asyouhadlastyea.r

在as/so…as结构中,后面的as也是关系代词,例如:

Youcanstayhereaslongasyoulike.

Thingsdonotgoonassmoothlyaswehoped.

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

如”,相当于andthis或andthat。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:

Asismentionedaboev,thismethodaimsatimprovingthestudentsinamoreeffectiveway.

Thetestiscancelled,asyouhavehope.d

Thetest,asyouhavehope,discancelled.

Amiconductormaterial,asthenameindicate,shaspoorerconductivitythanaconductor.

▲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:

Hefailedtopasstheexamagaina,sispredicted.

6

ability

Hefailedtopasstheexamagainw,hichannoyedhismothergreatly.

记住以下的as结构:

asisknowntoall众所周知),asisoftentheca情况常常如此),asthe

nameIndicates/suggests顾名思义),asmaybeimagined可以想象得出

,as

oftenhappens(这种情况常常发生

,ashasbeensaidbefore如前所述),as

hasbeenpointedout正女口已经指出的),aswillbeshownin(将在…中指

,asishoped(正如所希望的

3.2.8but的用法

but用作关系代词相当于who…not,which…not,that…notbut既可指人,也

可指物,常在定语从句中充当主语愤懑 或宾语。but本身含否定”的意思,它前面的主句

通常有否定”的词,如:(no,not,little,few,hardly等).but引导的肯定定语从

句和否定的主句连用,达到强烈肯定的修饰效果。例如:

Thereisnomotherbutlovesherownchildren(

Thereisnomotherthat

/whodoesnotloveherownchildren.)主语]

Thereisscarcelyagoodmoviebuthehan(

thathehasnoten).

Thereisneverafriendbutheremembersthebirthday0介词宾语]

Whoistherebutcommitrrors[but间或也可用在疑问句后]

Thereisnomanbuterrs=Thereisnomanwhodoesnoterr.主语]

Whathesawinthoplacesbutwasnotmirablebut=whichwasnot)(他所

到之处,看到的均是凄惨不已的景象。)[主语]

Thereareveryfewbutadmirehistalents.(很少有人不赞赏他的才干的。

But=whodon'

t

主语]

but结构有时可省略。例如:

(Thereis)Norulebuthaxceptions

(ThereareFewbooksbuthaveamisprintortwo

3.2.9than的用法

关系代词than一般用于含有比较级的句子中,兼有连词和代词的性质。例如:

Youspentmoremoneythanwasintendedtobespent

Shehasdonemuchmoreworkthanwasrequiredofher

7

Thequestionismorecomplicatedthanappearsonthesurface

3.3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。

+which/whom/who”

这时应注意介词与句中短语的搭配。例如:

TheproblemwithwhichIhavetroublehasnowbeensolved.

Oil,ofwhichthereareveraldifferenttyp,eisudformanypurposbycountriesallovertheworld.

Theman,becauofwhosheelpthemurdererwascaughtbythepol,iceiscomingtoourschooltomorrow.

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;

CanyoulendmeapenorpencilwithwhichIcanwrite?

Canyoulendmeapenorpencilthat/whichIcanwritewith?

Canyoulendmeapenorpencil(that)Icanwritewith?

Whoisthemantowhomyouweretalking?

Whoisthemanwhom/that/whoyouweretalkingt?o

Whoistheman(that)youweretalkingto?

如果介词过长,则不适于后置,例如:

Soundisatool,bymeansofwhichpeoplecommunicatewitheach

other.

Wemaybecaughtbyafire,incaofwhichwemustfindwaysto

escap.e

+介词+which/whom”引导的定语从句

Hereferredtoapersonthenameofwhomslippedbymemoryatthat

momen.t

8

Wehadadiscussionthepurpoofwhichwastofindasolutiontothisproblem.

在非限定性定语从句中,ofwhich/whom可用来修饰不定代词all,each,one,

many,much,more,most,any,some,afew,alittle,none,both,veral,thelatter,

theformer等。练习时,应该判断填空的部分为主句的定语从句还是与主句并列的

成分。例如:

Wehaveinterviewedmorethan50students,onlyafewofwhomgave

satisfactoryanswerstoourquestioj定语从句]

Wehaveinterviewedmorethan50students,butonlyafewofthemgave

satisfactoryanswerstoourquestions[并歹U]

Manypeoplecametohergraduationparty,mostofwhomwereherformer

classmates.定语从句]

Manypeoplecametohergraduationparty,andmostofthemwereher

formerclassmates.并[歹]

Thereare32studentsinourclass,upto20ofwhomarefromthesouth.

[定语从句]

3.3.4“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,女口

ca,fact,state,time,poin等。例如:

Waterboilsat100C,atwhichtemperatureitchangesintogasHewas

abouttoleave,atwhichmomentIcamebackhom.e

WeiHuaspentfouryearsintheUnitedStates,duringwhichperiodshe

studiedlaw.

Reader'sDigest,towhichwehavejustsubscribe,dhasanenormouscirculation.

3.4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:sinee,after和before。

9

3.4.1关系副词where(=at,inwhich)引导表示地点的定语从句

Thisistheplacewherehe'ndonis

thecitywhereshewasborn.

Thatistheplacewheretheymetforthefirsttim.e在表示“情况、方面、状

况”等有地点含义的抽象名词如ca,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underwhich。例如:

It'sakindgoafmewhereyoucantrainyoureyesight

Everyonemayfacethesituationwhereyouhavetomakeadecision

yourl.f

I'llshowhimthpeointwherehefailed.

Underthecircumstanceswherefoodshortageisthemostrious

May,whentheflowersareinfullbloom.

3.4.3关系副词why(=forwhich)引导表示原因的定语从句

Doyouknowthereasonwhyheleftthepartyearlythatnigh?t

Thereasonwhyshemisdthetrainisthatshewasheldupbyanaccident.

3.4.4其他关系副词引导的定语从句

2、当that在从句中作补语时可以省略

Georgeisnotthemant(hat)heudtob.e

Heisall(that)ateachershouldb.e

3、在therebe结构中出现定语从句,或在定语从句中出现therebe结构时,用做

主语的关系代词that可省略

Thereisamandownstairs(who)wantstoeyo.u

Thisisthebestdictionary(that)thereisinthelibrary.

That'saltlh(at)thereistoi.t(如此而已。)

Haveyounoticedanything(that)thereishappeninginthecompan?y

3.5.2关系副词的省略

1、当先行词是reason,而且在定语从句中做原因状语时,关系代词可用why或

that,可以省略

Thereason(why/that)hefailedwashislaziness.

Thatisthereason(why)Ididit.

2、当先行词是way,且在定语从句中作方式状语时,关系代词可用inwhich或谢霆锋资产

that,可以省略

Theway(inwhich/that)thecomradeslookatproblemisswrong.

what泛指上文或下文,意思是更....,尤其....”该结构常为插入语:

Sheisveryintelligent,andwhat

'

m

s

ore,veryhard-working.

Greatmenareoftenunknown,orwhatiswor,misknown.

Shedecided,whatwastheonlychoic,ethatshewouldkeepitacret.

3.6.2what=先行词+关系词

what相当于thething(s)which或theperson(s)that,既可以指人,也可指

物,意思相当于“••…的(人或物)”,此种情况的what本身已包含先行词,因而其

前不能再有先行词。what在其从句中可以做主语、宾语和表语。例如:

Thisiswhatyoucallfashion?

Thatixactlywhatyouaretoldtod?o

Neverpretendtobewhatyouareno.t

Sheiswhatwecallanoptimist.

363

“what名词”=“allthe名词+that”

what在从句中作定语。例如:

Onherdeath,theoldwomangavewhatpropertyshehadtotheyoungman

whostayedwithherduringthelastyearsofherlife.(=allthepropertythat)

Wewillgiveyouwhathelpwecan.(=allthehelpthat)

Hesharedwhatlittlewaterhehadwithhiscompanions.(=allthelittlewaterthat)

Whatpoemswehavelearnedatprenatreaboutlove.(=allthepoemsthat)

3.7先行词与其定语从句的分割

有时先行词与其定语从句会被其他的一些语法成分割裂开来,如:状语、定语

或谓语等。例如:

12

Wehavemadeanumberofcreativeadvancesintheoreticalrearchof

appliedsciencewhichareuptoadvancedworldlevels.

Doyourememberoneafternoontenyearsagowhenlcametoyourhou

andborrowedadiamondnecklafCe

Duringtheconstruction,problemsoftenariwhichrequiredesignchanges.

3.8定语从句与同位语从句的区别(详见

3.9关系代词与关系副词的判断

3.9.1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:

Thedayswhenwestayedtogethereunforgettable.(stay不及物)

I'IInerforgetthedayswhichIspentwithyouinTokyo.(spend及物,有

宾语)

Thisisthereasorwhyhedidnotcomethatmorningcome不及物动词)This

isthereasonwhich/thathefoundtoexcuforhimlffind及物动词

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:

muum,

youvisitedafewdaysago?

themuum_____theexhibitionwasheld.

h

在句1中,所缺部分为宾语,而where,that,onwhich都不能起到宾语的作

用,只有theone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inthemuum词组,可用介词in+

which引导地臭豆腐的做法 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,

13

something,anything,everything或nothing时,常用thereis来弓丨导。例如:I

don'twanttoconcentrateaonnythingthereisworryingme.

弓导条件从句的连词弓导条件从句的连词比较多,我们可以把它们分为以下几个大类:

1、表示“只要、只有”:as,as(so)faras,as(so)longas,onlyif,onlythat,

butthat:

As(So)longaswedon'ltoheart,we'llfindawaytoovercomethe

difficulty.

e

(Supposingw)ecan'gettenoughfoo,dwhatshallwedo?

Provided/Providing(thaty)ougivemeareceip,Itwillpaytherent.

Giventhatx=y,thenn(x+a)=n(y+a)mustbealsotrue.(多用于论证)

4、表示“除非”:unless(=ifnot)

Let'sgooutforawaulknlessyouaretootire.d

5、表示“一旦”:once

Once(=Ifonce)yousmoke,youcan'ebegins

tocr,ythereisnostoppingher.

6、各种复杂介词表示“条件是”:onconditionthat,onthe

understandingthat,ontheassumption/suppositionthat,withthe

proviso/stipulationthat,incaof,intheevento等。例如:

Iwillgivehimanythinghewantsonconditionthathewillshowgood

manners.

Dial119incaoffire.

不用连词引导的条件从句

WereIabird,Iwouldflytoyou.(虚拟语气)

Workhard,andyouwillsucceed.(祁使语气)

14

Youdoitagainj'IIkillyou.口语体

Afewdays'restyoudwillbeallrightagain.(名词+and)

Nothingventure,nothinghave.(没有主语和动词)

Timepermitting,wewillgotr病毒的来源 aveling.(分词独立主格结构)

在口语中,真实条件句广泛使用,人们通常用于表示对话语的态度(即起评注

性状语作用)。例如:

Ifyoudon'tminId',dliketothinkaboutthatforabit.

IfIrememberrightly,IthinkIhaveenyousomewhere.

Takeanothercup,ifyouplea.

4.2让步从句(ClauofConcession)

让步是对比的一个特殊变体,表达的意义是

“Yesbut…”,使用让步连

接词时,说话人/作者希望表达在承认一个命题正确和确信另一个命题也正确的情

况下,削弱第一个命题的重要性,主句中的意思往往是最重要的中心意思,正是

▲注意:当有though,although时,后面的从句不能有but,但是though和yet可

连用。例如:

Thoughheisrich,yetheisnothappy.

though还可以用做副词,放在句末。例如:

Itwashardwork;Ienjoyedit,though.=Itwashardwork,butIenjoyedit.

2、everif,eventhough即使”

Nomatterwhathappene,dhewouldnotmind.

Whateverhappened,hewouldnotmind.

NomatterwhatIsayorhowIsayi,thealwaysthinksI

Don'tlettheminw,hoever(=nomatterwho)theyare.

▲注意:nomatter+疑问词不能引导主语从句和宾语从句。

'mwrong.

(x)Nomatterwhatyousayisofnounow.

Theenterpri,beitassmallasitma,yrequiresgreatability.

Lettheconquencesbewhattheym,haeyremainsfirm.

6、while,whereas

while引导的让步从句,一般放在句首,含有前后对照之意:

Whilewedon'tagreweecontinuetobefriends.

whereas要求两个情境之间有对偶关系:

Somestudythecretoflongevity,whereasothersstudythemethodof

killing.

1、介词短语+名词/如:for,inspiteof/despite/irrespectiveof/regardless

of/notwithstandingthefactthat

Muchasshehatedcrueltys,hecouldn'thelpwatchingthefight.

▲注意:这种用法中,though/that可以替换as

但although没有这种用法,句首

名词不能带任何冠词,句首如果是实义动词,其他助动词放在主语后,如果实义动

词有宾语和状语,要一起放在主语之前。例如:

Childas/that/thoughheis,hecanspeakfiveforeignlanguages.=Though

heisachild,

Tryhardashewill,heneveremsabletodotheworksatisfactorily.=

Thoughhetrieshard,heneverems

除when和whereas之外,其他让步从句的连词可引导-ing/-ed和无动词从
