第十三章名词性从句名词性从句用法讲解与专项练习题及答案名词性从句包括主语从句、宾语从句、表语从句和同位语从句。高考常从连接词的选择、语序、语气、时态等方面来考查。名词性从句中的连接词有连词that/whether/asif，连接代词what/who/which/whose/whatever/whoever/whomever/whichever，连接副词where/when/why/how/wherever/whenever。第1讲引导名词性从句的连接词考点1.引导名词性从句的连接词有哪些有学生认为，引导同位语从句只能用that,这句话对吗？先看下面几个句子。①Ihavenoquestionthathewillcome.②Ihaveaquestionwhetherhewillcome③Ihaveaquestionwhenhewillcome.我们可以看出：上面三个句子中question后面都是同位语从句，都是说明question的内容的。在句①中，同位语从句的原句是陈述句，由that引导；在句②中，原句是一般疑问句，由whether引导；在句③中，同位语从句的原句是特殊疑问句，特殊疑问词也起着连接作用。其实，所有名词性从句的连接词都有上面的三种情况。宾语从句：Idon’tknowthathewillcome.Idon’tknowwhether/ifhewillcome.Idon’tknowwhenhewillcome.表语从句：WhatIdon’tknowisthathewillcome.WhatIdon’tknowiswhetherhewillcome.WhatIdon’tknowiswhenhewillcome.主语从句Thathewillcomeisobvious.Whetherhewillcomeisn’tknownyet.Whenhewillcomeisn’tknownyet.1.【2010浙江】Itisuncertain______sideeffectthemedicinewillbringabout,althoughabouttwothousandpatientshavetakenit.A.thatB.whatC.howD.whether2.【2012全国新课标】Itisbynomeansclear______thepresidentcandotoendthestrike.A.howB.whichC.thatD.what3.【2012山东】Itdoesn’tmatter______youpaybycashorcreditcardinthisstore.A.howB.whetherC.whatD.why4.【2013陕西】Itremainstobeseen______thenewlyformedcommittee’spolicycanbeputintopractice.A.thatB.whichC.whatD.whether5.【2009天津】Itisobvioustothestudents______theyshouldgetwellpreparedfortheirfuture.A.asB.whichC.whetherD.that6.【2012江西】Itsuddenlyoccurredtohim______hehadlefthiskeysintheoffice.A.whetherB.whereC.whichD.that考点2.引导词that的省略问题主语从句、表语从句、同位语从句中连词that不能省略。ThattheyaregoodatEnglishisknowntousall.Theproblemisthatwedon’thaveenoughmoney.SheexpressedherhopethattheywouldcometoChinaoneday.只有宾语从句中的连接词that可省略，但在以下几种情况中that也不能省略：A.当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时，that不可省略。Hejudgedthat,becausehewasachild,hedidnotunderstand.B.当两个名词性从句并列作宾语时，后面的that不能省。Everyoneknewwhathappenedandthatshewasworried.C.当that作介词宾语时，that不可省掉。Thereasonliesinthatsheworksharderthantheothersdo.7.______weneedmorepracticeisquiteclear.A.WhenB.WhatC.ThatD./8.______fashiondiffersfromcountrytocountrymayreflecttheculturaldifferencesfromoneaspect.A.WhatB.ThatC.ThisD.Which9.【2010上海】Onereasonforherpreferenceforcitylifeis______shecanhaveeasyaccesstoplaceslikeshopsandrestaurants.A.thatB.howC.whatD.why10.ThereasonwhyIdidn’tgotoShanghaiwas______anewjob.A.becauseIgotB.becauseofgettingC.IgotD.thatIgot11.【2011全国I】Thenextthinghesawwassmoke______frombehindthehouse.A.roseB.risingC.toriseD.risen12.Havingcheckedthedoorswereclosed,and______allthelightswereoff,theboyopenedthedoortohisbedroom.A.whyB.thatC.whenD.where13.Iknownothingabouttheyounglady—______sheisfromBeijing.A.exceptB.exceptforC.exceptthatD.besides14.Humanbeingsaredifferentfromanimals___theycanuselanguageasatooltocommunicate.A.forthatB.inthatC.inwhichD.forwhich(如果不理解本题，可以参看P.错误!未定义书签。错误!未找到引用源。)考点3.whether与if引导名词性从句时的区别第十三章名词性从句A.在主语从句、表语从句、同位语从句中只能用whether,不能用if。Whetherthemeetingwillbeputoffhasnotbeendecidedyet.Thequestioniswhethertheyhavesomuchmoney.Weoughttodiscusscarefullythequestionwhetherwecandoitornot.B.在宾语从句中whether和if可以互换，但：i.作介词宾语时连接词一般用whether。如：Italldependsonwhethertheywillcomeback.ii.后面直接跟ornot时用whether。如：Ididn’tknowwhetherornothehadarrivedinWuhan.C.whether也可与动词不定式连用，但if不能。Ihavenotdecidedwhethertogoornot.D.whether常与or连用表示一种选择，if不能这样用：Thequestionofwhethertheyaremaleorfemaleisnotimportant.E.whether可引导一个让步状语从句表示“不管”、“无论”，而if不能。如：Whetherhecomesornot,wewillbeginourpartyontime.F.discuss后通常用whether。15.______youcansucceedintheendwillmainlydependon______youdoand______youdoit.A.If;what;whyB.Whether;what;howC.Whether;how;whyD.That;whether;how16.【2009上海】Itisnotimmediatelyclear______thefinancialcrisiswillsoonbeover.A.sinceB.whatC.whenD.whether17.Theydiscussed______theycouldsettletheproblemwithoutothers’help.A.ifB.thatC.whatD.whether18.Whatthedoctorisuncertainaboutis______mymotherwillrecoverfromtheseriousdiseasesoon.A.whenB.howC.whetherD.why19.Mr.Hopkinshasnotyetansweredmyquestion______Icangowithhimto______hecallstheUndergroundTreasureHousenextweek.A.that;whichB.that;whereC.whether;thatD.whether;what20.Ihavenoidea______ornothehasfinishedthework.A.ifB.thatC.whetherD.which考点4.question与doubt后跟同位语从句时的连接词问题doubt，question用于肯定结构时，后面用whether引导名词性从句；用于否定结构或疑问结构时，后面用that引导名词性从句。besure用于肯定句或疑问句时，后接that引导的名词性从句；用于否定句时，后接whether/if引导的名词性从句。21.Ihavenoquestion______hewillsucceed.A.whetherB.thatC.whenD.how22.ThenIhadaquestion______aspore（孢子）couldquicklygetaroundandformmould(霉菌).A.whyB.thatC.thathowD.if23.Thequestioncameupatthemeeting______wehadenoughmoneyforourresearch.A.thatB.whatC.whichD.whether24.Idon’tdoubt______he’llcome.A.thatB.ifC.whatD.whether25.Afterthreedays’waiting,therewasalittledoubtinthemother’smind______thepolicecouldfindherlostchild.A.howB.thatC.whereD.whether考点5.名词性从句是复合句时，不要忘了带that(双连接词)改错:①Thequestionwasthatwhetherhecouldgetajobatthecenter.②Youhavenoideathathowbusywewerethosedays.③Itiswellknownwhatapersoneatscauseschangesinthebody.答案及解析：①去掉that,。后面whether本身就起着连接作用。②去掉that。who,how,when,what等本身就有两个作用：作从句的成分；起连接作用。③在what前面加that。what只是把主语从句的两个分句连接起来，但其作为一个整体来作主语从句时还需要用that引导。26.Fathermadeapromise______Ipa
