高考必考语法精讲精练语法专题九：定语从句定语从句是比较重要的语法项目。《2017年普通高等学校招生全国统一考试大纲》附录语法项目表中将定语从句列为必考项。全国卷新课标Ⅰ对定语从句的考查一般在语法填空和短文改错中，主要考查定语从句引导词的用法。2015年

高考全国卷Ⅰ第64题（语法填空）考查了定语从句引导词that/which。2016年高考全国卷Ⅰ第65题（语法填空）考查了定语从句的引导词when。2017年高考全国卷Ⅰ第70题（语法填空）考查了定语从句的引导词whi

ch。基本概念：定语从句:在复合句中修饰名词或代词、充当定语的句子叫定语从句。因其功能相当于形容词，所以又称为形容词性从句。先行词:被定语从句所修饰的名词或代词。关系词:引导定语从句的词，也叫引导词。分为关系代

词（who，whom，that，which，whose,as）和关系副词(where，when，why)。关系词要在定语从句中作某个成分，如主语、宾语、状语等。限制性定语从句：对先行词起修饰限定作用的定语从句

。非限制性定语从句：对先行词或主句起补充说明作用的定语从句，通常引导词和先行词之间用逗号隔开。关系词及其意义：关系代词和关系副词功能有三个：①用来引导定语从句，在先行词和定语从句之间起纽带作用，使二者联系起来。②关系代词和关系副词可作定语从句的一个成分。关系代词可

作主语、宾语、定语；关系副词可作状语。③关系代词和关系副词在从句中代替在他前面的先行词。关系词先行词从句成分例句备注关系代词who人主语Doyouknowthemanwhoistalkingwithyourmother?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thatwhom人宾语Mr.SmithisthepersonwithwhomIamworkingTheboy(whom)sheloveddiedinthewar

..whose人或物定语Ilikethosebookswhosetopicsareabouthistory.Theboywhosefatherworksabroadismydeskmate.that人或物主语、宾语Aplaneisamachinethatcanfly.

Sheisthepopstar(that)Iwanttoseeverymuch.which物主语、宾语Thebook(which)Igaveyouwasworth$10.Thepicturewhichwasabouttheaccidentwaster

rible.as人或物主语、宾语Heissuchapersonasisrespectedbyallofus.ThisisthesamepenasIlostyesterday.as做宾语一般不省略关系副词when时间时间状语I

willneverforgetthedaywhenwemetthere.可用onwhich替换where地点地点状语ThisisthehousewhereIwasborn.可用inwhich替换why原因原因状语

Ican’timaginethereasonwhyheturneddownmyoffer.可用forwhich替换一、关系代词引导的定语从句1．who指人，在定语从句中作主语。①TheboyswhoareplayingfootballarefromClassOne.②Ye

sterdayIhelpedanoldmanwhohadlosthisway.③Thatistheteacherwhoteachesusphysics.2．whom指人，在定语从句中做宾语，常可省略。①MrLiuistheperson(whom)youtal

kedaboutonthebus.②LiMingisjusttheboy(whom)Iwanttosee.③Theprofessor(whom)youarewaitingforhascome.④Thegirl(whom)theteach

eroftenpraisesisourmonitor.注意：关系代词whom在口语或非正式文体中常可用who来代替，也可省略。Theman(whom/who)youmetjustnowismyoldfriend.3．which指物，在定语从句中做主语或宾语，做

宾语可省略。①Footballisagamewhichislikedbymostboys.②Thefactorywhichmakescomputersisfarawayfromhere.③Helikestoreadbookswhicharewrittenbyforeignwriters.④Th

ehousewhichisbythelakelooksnice.⑤Thisisthepen(which)heboughtyesterday.⑥Thefilm(which)theysawlastnightwasnotinterestingata

ll.4．that指人时，相当于who或whom；指物时，相当于which。在定语从句中作主语或宾语，作宾语时常可以省略。①Thenumberofpeoplethat/whocometovisitthiscityeveryyearreachesonemillion.②W

hereisthemanthat/whomIsawthismorning?③Thepersonthat/whomyouintroducedtomeisverykind.④Theseasonthat/whichc

omesafterspringissummer.⑤YesterdayIreceivedaletterthat/whichcamefromAustralia.5．whose通常指人，也可指物，在定语从句中做定语。①Ivis

itedascientistwhosenameisknownalloverthecountry.②Hehasafriendwhosefatherisadoctor.③Ioncelivedinthehousewh

oseroofhasfallen.注意：指物时，常用下列结构来代替：①Theclassroomwhosedoorisbrokenwillsoonberepaired.②Theclassroomthedoorofwhichisbrokenwillsoonber

epaired.③Doyoulikethebookwhosecoverisyellow?④Doyoulikethebookthecoverofwhichisyellow?关系代词that与which的区别（一）只用that不用which的情况：1

、先行词是everything,nothing,anything,much,little,none等不定代词或由不定代词any,some,no,much,few,little,every,all等修饰时,引导定语从句用that不用which。例如：①Fi

nally,thethiefhandedeverythingthathehadstolen.②Thereseemstobenothingthatisimpossibletohimintheworld.③ThereislittlethatIcandoforyou.

2、先行词被形容词最高级或序数词修饰且指物时,引导定语从句用that。例如：①ThisisthebestbookthatIhaveeverread.②ThefirstplacethattheyvisitedinLond

onwastheBigBen.3、先行词中既有人又有事物时，引导定语从句用that。如：①Wetalkedaboutthethingsandpersonsthatwesawthen.②Lookattheman

andhisdogthatarewalkingupthestreet.4、先行词被theonly，thevery,justthe等修饰且指物时,引导定语从句用that。例如：ThisistheverydictionarythatIwanttobuy.注意：当先行词指人时，偶

尔也可用关系代词who。例如：HeistheonlypersonthatIwanttoseenow.5、当先行词前面有who/which等疑问代词时，只用that。例如：①Whoisthemanthatisstandingthere?②WhichistheT-shirtthatfitsmemo

st?6、定语从句内容为解释名词的性质、概念时，需用that。例如：Aplaneisamachinethatcanfly.（二）只用which不用that的情况1、指物，介词后。例如：IstillrememberthedayonwhichIfirstgottoParis.2、用于非限制定语

从句中。例如：Sheheardaterriblenoise，whichbroughtherheartintohermouth.3、先行词是that,those时。例如：ThatisthebookwhichIborrowed

fromthelibrary.4、一个句子有两个定语从句，为避免重复，一个用that，另一个用which。例如：Isthereanythingthatisnotexpensivewhichwecanbuyforherasagift?二、theway作先行词的

定语从句比较下列句子，理解关系词，并分析原因：①Theway(that/inwhich/×)heansweredthequestionwassurprising.②Idon’tliketheway(that/in

which)youlaughather.归纳：（1）当关系词在定语从句中作状语时，关系词用inwhich，that或者省略；（2）当关系词在定语从句中作主语时，关系词用that或which；（3）当关系词在定语从句中作宾语时，关系词用that，which或省略。三、介词+关

系代词引导的定语从句关系代词在定语从句中作介词宾语时，从句常常由“介词+关系代词”引出。①Theschool(which/that)heoncestudiedinisveryfamous.=Theschool

inwhichheoncestudiedisveryfamous.②I’llbringherethemagazine(which/that)youaskedfor.=I’llbringherethemagazineforw

hichyouasked.③Thisistheboy(whom/who/that)Iplayedtenniswithyesterday.=ThisistheboywithwhomIplayedtennisyesterd

ay.④We’llgotohearthefamoussinger(whom/who/that)wehaveoftentalkedabout.=We’llgotohearthefamoussingeraboutw

homwehaveoftentalked.1、单个介词（in/with/on/by）+关系代词(whom,which)①ThetwothingofwhichtheyfeltveryproudwereJim’sgoldwatchandDella’sh

air.②Aharvesterisamanwhoisharvestingoramachinewithwhichweharvestcrops.注意：介词确定的依据A、依从句中的动词,形容词,名词与介词的固定搭配而定；B、依先行词与从句中动词的关系及所表达的含义而定。2、介词短语

+关系代词(which,whom,whose)常用的介词短语有:someof,bothof,asaresultof,atthebackof，becauseof,infrontof,inthemiddleof,atthebottomof,onthetopof,att

hefootof等。①Thereisagreatpaininmyrightfoot,becauseofwhichIcanonlylimpalong.②Theyarrivedatafarmhouse,infrontofwhichsatanoldman.注意:含有介词的动词短语一般不能拆开,如loo

kafter,lookfor,takecareof,takepartin,lookforwardto等。例如：①Thisisthewatch(which/that)Iamlookingfor.(正)②ThisisthewatchforwhichIamlooking.(误)③Thebabies(w

hom/who/that)thenurseislookingafterareveryhealthy.(正)④Thebabiesafterwhomthenurseislookingareveryhealthy.（误）3、单个介词+关系代词(

which,whose)+名词介词要依介词与关系代词后的名词的搭配习惯而定。例如：①HelivedinLondonforthreemonths,duringwhichtimehelearnedsomeEnglis

h.②OurEnglishteacher,withwhosehelpwehavemadegreatprogressinEnglish,hascompletedthirtyyearsofteaching.4、the+名词+of+关系代词(which,wh

om)结构中的名词和后面的关系代词有所属关系。例如：ThisisthebookthecoverofwhichisdesignedbyMrJones.=Thisisthebook,whosecoverisdesignedbyMrJones.5、部分词汇/结构

+of+关系代词(1)all,both,none,neither,either,many,most,few,several,enough,half,some,any,one,two,three,themajority,anumber,theyoungest等。(2)数词(基数词,序数词,百分

数,分数)+名词(3)the+形容词最高级/比较级①Herearetwopairsofsocks,eitherofwhichyoumaychoose.②Thefootballteamhas15members,theoldestofwhomis25yearsold.

③Heloveshisparentsdeeply,bothofwhomareverykindtohim.④Therearemanyapples,someofwhichhavegonebad.⑤Therearefortystudentsinourc

lass,mostofwhomarefrombigcities.⑥Hehaswrittentenstories，threeofwhichareaboutcountrylife.四、关系代词as与which的用法as和which引导非限

制性定语从句时，其用法有相同之处，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宾语，代表前面整个句子。如：①Hemarriedher,as/whichwasnatural.②Heishonest,as/whichwecansee.2.as引导

的非限制性定语从句可以放在主句之前、主句之后，甚至还可以分割主句。which引导的非限制性定语从句只可放在主句之后。另外，as常常有“正如、正像”的含义。如：①Asisknowntoall,Chinaisade

velopingcountry.②Heisfromthesouth,aswecanknowfromhisaccent.③John,asyouknow,isafamouswriter.④Theairqualityinth

ecity,asisshowninthereport,hasimprovedoverthepasttwomonths.(2012·福建高考)⑤HehasbeentoParistentimes,whichIdon’tbeliev

e.注意：当主句和从句之间存在着逻辑上的因果关系时，关系词往往只用which。如①Tomwaslateforschoolagainandagain,whichmadehisteacherveryangry.②Thistableismadeofmetal,whichmadeitve

ryheavy.3.当先行词受such,thesame修饰时，关系词常用as。如：①I’veneverheardsuchstoriesashetells.②Heisnotsuchafoolashelooks.③ThisisthesamedictionaryasIlo

stlastweek.注意：当先行词受thesame修饰时，也可能用that引导定语从句，但与as引导的定语从句意思有区别。如：SheworethesamedressthatsheworeatMary’swedding.她穿着她在玛丽婚礼

上穿过的同一条连衣裙。Sheworethesamedressasheryoungersisterwore.她穿着跟她妹妹所穿的一样的连衣裙。五、关系副词引导的定语从句1.when指时间，在定语从句中作时间状语。①Istillrememberthe

daywhenIfirstcametothisschool.②Thetimewhenwegottogetherfinallyarrived.③October1,1949wasthedaywhenthePeople’sRepublicofChinawasfounded.

2.where指地点，在定语从句中作地点状语。①ShanghaiisthecitywhereIwasborn.②ThehousewhereIlivedtenyearsagohasbeenpulleddown.③Ivisitedthefarmwhe

realotofcowswereraised.④Isthistheplacewheretheyfoughttheenemy?3.why指原因，在定语从句中作原因状语。①Pleasetellmethereasonwhyyoumissedtheplane.②Thereasonwhyhewa

spunishedisunknowntous.③Idon’tknowthereasonwhyhelooksunhappytoday.注意：引导定语从句的关系副词可以用“介词+which”来替换。例如：①Istillrememberthedaywhen(=onwhi

ch)Ifirstcametothisschool.②Greatchangeshavetakenplacewhere(inwhich)welive.③Thereasonwhy(=forwhich)herefusedtheinvitationisquiteclear.六、一些

特殊词之后的where如果定语从句用来修饰point,situation,part,condition和case等表示抽象意义的词，并且作状语．．．，要用where引导定语从句，意思是“到了某种地步，在某种境况中”，这种现象叫做地点模糊化．．．．．。常见的表地

点的模糊化名词还有：occasion,circumstance,state,degree,extent,stage,level,period,aspect等。例如：①IhavecometothepointwhereIcan’tstandhi

m.②Thecountryisinthesituationwhereawarwillbreakoutatanytime.③Wearetryingtoreachapointwherebothsideswillsitdowntogetherandtalk.④Icanthinkofm

anycaseswherestudentsobviouslyknowalotofEnglishwordsandexpressionsbutcouldn’twriteagoodessay.⑤It’shelpfultoputchildreninasituationwherethe

ycanseethemselvesdifferently.注意：如果不作状语，则用关系代词that/which。例如：Rememberthatthereisstillonepointwhichwemustmakeclearattheconferencetomorrow.高考

英语短文改错及语法填空分析与训练·定语从句考点规律分析:定语从句短文改错考点主要涉及定语从句引导词的误用、缺失以及多余；语法填空主要考查根据先行词及上下文填合适的引导词。定语从句单句改错之真题训练：1.…inotherplacesyouarelimite

错之真题训练：1.that改为which，因介词后要用which来引导定语从句2.去掉when或将when改为that，因这里的定语从句中谓语动词(spent)缺宾语，故只能用关系代词that或将其省略3.wher

e改为which，因此处要填关系代词作主语4.who’s改为whose，因who’s=whois，不仅结构错误，而且意思也不通；whose引导定语从句，表示“……的”定语从句单句改错之模拟训练：1.his改为whose，whose在此引导定语从句。2.whi

ch改为where，where引导定语从句且在从句中用作状语；此题还可在staying后加in。3.where改为which/that，也可去掉where，因visit为及物动词，此处应用关系代词作其宾语（也可省略）。4.where改为whic

h，which在此引导非限定性定语从句，且在从句中用作宾语(用作visit的宾语)。5．what→which/that或去掉what考查定语从句，并在从句中作宾语，指物，用关系代词that/which，也可省略。定语从句单句改错之提升训练：1.where→that/wh

ich或去掉where。2.把for放在looking之后。英语中,有些短语动词,介词或副词不可与动词相分离。又如:lookafter,runinto等。3.who→whom。尽管在口语中who,whom都能作宾语

,但在介词后只能用whom。4.that→which。5.that→which。that不可以引导非限制性定语从句。6.which→that或去掉which。当先行词被all,every,no,some,any,little等修饰时,常用that引导定语从句。7.which→

that或去掉which。当先行词被序数词、形容词的最高级或theonly,thevery等所修饰时,常用that引导定语从句。8.who→that。如果先行词既指人又指物时,常用that引导定语从句。9.w

hich→that或去掉which。当先行词为something,anything,everything,nothing,all等时,常由that引导定语从句。10.that→which。11.which→why/which前加for或去掉which。12.wan

ts→want。定语从句中谓语动词的数应与先行词一致。13.his→whose。14.them→whom或both前加and。15.去掉there。16.have→has。当oneof+名词复数作先行词时,

从句的谓语用复数;但是当one前有the(only)时,从句谓语要用单数。17.which→that/which前加in或去掉which。18.Those后加who。19.第二个who→that。当主句是以who或which开头的疑问句时,定语从句常用that引导,以避免重

复。20.which→when或which前加in。定语从句单句语法填空之真题训练：1．when[由句子结构可以判断这是一个定语从句，先行词是表示时间的inthemid－1980s，从句中缺少状语，因此填写关系副词when

从句。句意：科学家们已经提出许多关于人类为什么哭泣会流泪的理论，其中没有一个已被证明的。分析句子成分可知，空处引导定语从句，此处是非限制性定语从句，which代替manytheories，故应用which引导该定语从句。]11.as[句意：据报道，吸烟者的数量在一年内下降了17%。as引

导的定语从句，在这里作主语，意为“正如……，这一点”，代替整个主句的内容。]12．which[句意：这真是一个令人开心的地方，它看起来和一百年前一模一样，有着蜿蜒的街道和漂亮的小屋。which代替先行词place，在定语从句中用作主语，引导非限制性定语从句。不可用that。]13．wh
