高中名詞性從句講解與練習(xí)(包含答案)

名詞性從句 名詞性從句相當(dāng)于名詞，可分別作主句的主語、表語、賓語和同位語。因此，名詞性從句分為主語從句、表語從句、賓語從句和同位從句。（一）引導(dǎo)名詞性從句的連接詞類別詞義在從句中的作用that無任何詞義僅起連接作用，在從句中不充當(dāng)任何句子成分；一般可以省略，但是在句首不可省略。if和whether意為“是否”，表明從句意義的不確定性起連接作用，在從句中不充當(dāng)任何句子成分關(guān)系代詞：who,what,which,whom,whose,whatever,whoever,whomever,whichever有各自自身的意義起連接作用，并在從句中充當(dāng)主、表、賓、定語等關(guān)系副詞：when,where,why,how,however,whenever,wherever有各自自身的意義起連接作用，并在從句中充當(dāng)狀語（二）主語從句1.主語從句在復(fù)合句作主語。 e.g.Whowillgoisnotimportant. 2.that引導(dǎo)主語從句時，不能省略。 e.g.Thathesuddenlyfellilllastweekmadeussurprised. 3.用it作形式主語，主語從句放在句末。It+系動詞+形容詞+that從句.necessary,right,likely,wrong,important,certain,clear...It+系動詞+名詞+that從句.apity,ashame,afact,nowonder...It+be+動詞ed+that從句.said,told,reported,suggested,consideredIt+特殊動詞+that從句.seem,turnout,appear,matter...e.g.Itdoesn’tmattersomuchwhetheryouwillcomeornot.4.whether引導(dǎo)的主語從句可放句首，而if引導(dǎo)的主語從句不能放句首，只能放句末。Whethertheworkedcanbecompletedontimeisdoubtful.Itisdoubtfulwhether/iftheworkcanbecompleted.（三）表語從句 1、表語從句在復(fù)合句中作表語，位于系動詞之后。 e.g.Thequestionwaswhocouldgothere. 2、引導(dǎo)表語從句的連接詞that有時可省去。 e.g.Myideais(that)wecangetmorecomradestohelpinthework.3.一般不用if引導(dǎo)表語從句，用whether.Thequestioniswhetherwecanreducethecostoftheproduct.其他連接詞：asif,asthough,because,as,like.Itsoundsasif/thoughhehasbeenreallyill.5.主語為reason：表語從句中的連接詞要用that，不用why.Thereasonwhyhewasunhappyisthathehaslosthiskeys.表語從句中的虛擬語氣.（四）賓語從句 1、賓語從句在復(fù)合句中作賓語。引導(dǎo)賓語從句的連詞that一般可省略。 e.g.Ihope(that)everythingisallright. 2、介詞之后的賓語從句，不可用which或if連接，要分別用what或whether。 e.g.I’minterestedinwhetheryou’vefinishedthework.. I’minterestedinwhatyou’vesaid. 3、whether與if都可以引導(dǎo)賓語從句，常可互換。但下面情況不能互換。①賓語從句是否定句時，只用if，不用whether。e.g.Iwonderifitdoesn’train.②用if會引起誤解，就要用whether。e.g.Pleaseletmeknowwhetheryouwanttogo.7.Hewascriticizedfor_____.A.hehaddoneit B.whathehaddone C.whathadhedone D.thathehaddoneit8.Wouldyoukindlytellme_____?A.howcanIgettotheBeijingRailwayStation B.howIcangettotheBeijingRailwayStationC.wherecanIgettotheBeijingRailwayStationD.whethercanIgettotheBeijingRailwayStation9.Mrs.Smithwasverymuchimpressedby_____.A.whathadsheseeninChina B.thatshehadseeninChinaC.whatshehadseeninChina D.whichhadsheseeninChina10.Wetookitforgranted___A.thattheywerenotcoming B.thatweretheynotcomingC.theywerecomingnot D.weretheynotcoining11.Ireallydon'tknow_____A.Ishoulddonext B.whatshouldIdonextC.whatIshoulddonext D.howIshoulddonext12.I'mafraid_____.A.thelittlegirlwillhavetobeoperatedonB.thatwillthelittlegirlhavetooperateonC.thelittlegirlwillhavetooperateonD.thatwillthelittlegirlhavetobeoperatedon13.Shewalkedupto_____.A.wheredidIstand B.whereIstood C.Istoodthere D.whereIstoodthere14.Canyoutellme_____?A.whoisthatgentleman B.thatgentlemaniswhoC.whothatgentlemanis D.whom.isthatgentleman15.We'llgiveyou_____.A.thatdoyouneed B.whatdoyouneedC.whateveryouneed D.whetherdoyouneed16.Theywantustoknow_____tohelpus.A.whatcantheyB.whattheycan C.howtheycanD.howcanthey17.Wemustput_____intopractice.A.whatwehavelearned B.thatwehavelearnedC.thathavewelearned D.whathavewelearned18.Didshesayanythingabout_____?A.thattheworkwastobedone B.howwastheworktobedoneC.thatwastheworktobedone D.howtheworkwastobedone19.Hewasneversatisfiedwith_____.A.whatshehadachieved B.hadwhatsheachievedC.shehadachieved D.thatsheachieved20.Thesephotographswillshowyou_____.A.whatdoesourvillagelooklike B.whatourvillagelookslikeC.howdoesourvillagelooklike D.howourvillagelookslike21.Peterinsisted_____hepaythebill.A.onthat B.what C.that D.onwhich22.Theyurged_____thelibraryopenduringthevacation.A.when B.where C.why D.that23.Wewishwecouldhavelearned_____whenwewereathighschool.A.whatyoudid B.thatyouhaddoneC.thatwhatyoudid D.whatdidyoudo24.1willdescribetoyou_____Isawwhenthere.A.what B.that C.whichD./25.From_____Ishouldsayheisagoodworker.A.what1knowofhim B.thatIdoknowofhimC.whatdoIknowofhim D.thatdoIknowofhim26.Iwillgivethisdictionaryto__wantstohaveit.A.whomeverB.anyone C.whoever D.someone27._____theywillcomeherehasn'tbeendecidedyet.A.What B.That C.When D.Where28._____wassaidheremustbekeptsecret.A.WhoB.Thething C.Whatever D.Where29.Itisstillaquestion_____weshallhaveoursportsmeet.A.if B.that C.what D.when30.I'mgoinganyway._____shewillgoisuptohertodecide.A.Ifornot B.Whetherornot C.If D.That31.Itisstrange_____shehasleftwithoutsayingaword.A.that B.what C.why D.how32.Itisveryclear_____ourpolicyisacorrectone.A.what B.that C.whyD.where33._____Mr.Zhangsaidisquiteright.A.That B.When C.What D.Whether34.Ithasbeendecided_____hewillbesentthere.A.if B.whether C.why D.that35.Itdoesn’tmatter_____he'scomebackornot.A.if B.whether C.that D.when36.It'sagreatpity_____wewon’tbeabletofinishthetaskontime.A.when B.that C.whyD.where37.Ithappened_____Iwasn'ttherethatday.A.when B.why C.where D.that38._____youhavedonemightdoharmtootherpeople.A.
