英语总复习语法系列训练名词性从句第1页第1页一、引导名词性从句连接词在句子中起名词作用句子叫名词性从句(NounClauses）。名词性从句功效相称于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此依据它在句中不同语法功效，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

引导名词性从句连接词可分为三类：

连接词：that,whether,if(不充当从句任何成份）连接代词：what,whatever,who,whoever,whom,whose,which.连接副词：when,where,how,why不可省略连词：1.介词后连词2.引导主语从句和同位语从句连词不可省略。Thatshewaschosenmadeusveryhappy.Weheardthenewsthatourteamhadwon.第2页第2页whether与if均为“是否”意思。但在下列情况下，whether不能被if所取代：1.whether引导主语从句（包括从句在句首位置）应当用whether，不用if，如：

Whetheritistrueremainsaproblem.

Whetherhewillcome,Iamnotsure.2.引导表语从句用whether，不用if，如：

Thequestioniswhetheryoushouldacceptit.3.whether能够引导从句作介词宾语，而if则不能，如：I’mnotinterestedinwhetherthey’llgoornot.Itdependsonwhetherwehavegotenoughmoney.

4.whether能够直接跟动词不定式连用，而if则不能，如：Ididn’tknowwhethertolaughortocry.Shehasn’tdecidedwhethertogoornot.5.引导同位语从句用whether，不用if，如：

Thequestionwhetherhe’llattendthemeetingisvital.★大部分连接词引导主语从句都可置于句末，用it充当形式主语。Itisnotimportantwhowillgo.第3页第3页二、名词性that-从句1）由从属连词that引导从句叫做名词性that-从句。that只起连接主句和从句作用，在从句中不担任任何成份，本身也没有词义。名词性that-从句在句中能充当主语、宾语、表语、同位语和形容词宾语，比如：主语：Thatheisstillaliveissheerluck.宾语：JohnsaidthathewasleavingforLondononWednesday.表语：Thefactisthathehasnotbeenseenrecently.同位语：Thefactthathehasnotbeenseenrecentlydisturbseveryoneinhisoffice.形容词宾语：Iamgladthatyouaresatisfiedwithyourjob.2）that-从句作主语通惯用it作先行词，而将that-从句置于句末，比如：Itisquiteclearthatthewholeprojectisdoomedtofailure.It'sapitythatyoushouldhavetoleave.第4页第4页a.It+be+形容词+that-从句

Itisnecessarythat… 有必要……

Itisimportantthat… 主要是……

Itisobviousthat… 很明显……b.It+be+-ed分词+that-从句

Itisbelievedthat… 人们相信……

Itiswellknownthat… 从所周知……

Ithasbeendecidedthat… 已决定……c.It+be+名词+that-从句

Itiscommonknowledgethat… ……是常识

Itisasurprisethat… 令人惊奇是……

Itisafactthat… 事实是……d.It+不及物动词+that-分句

Itappearsthat… 似乎……

Ithappensthat… 恰巧……

Itoccurredtomethat… 我忽然想起……用it作形式主语that-从句有以下四种不同搭配关系：第5页第5页三、名词性wh-从句1）由wh-词引导名词从句叫做名词性wh-从句。wh-词包括who,whom,whose,whoever,what,whatever,which,whichever等连接代词和where,when,how,why等连接副词。wh-从句语法功效除了和that-从句同样外，还可充当介词宾语、宾语补语和间接宾语等，比如：主语：Howthebookwillselldependsonitsauthor.直接宾语：Don’tputoffwhatyoucandotodaytilltomorrow.间接宾语：Theclubwillgivewhoeverwinsaprize.表语：Myquestioniswhowilltakeoverthepresident.

宾语补足语：Shewillnamehimwhatevershewantsto.同位语：Ihavenoideawhenhewillreturn.形容词宾语：I'mnotsurewhysherefusedtheirinvitation.

介词宾语：Thatdependsonwhereweshallgo.2）wh-从句作主语也惯用先行词it做形式主语，而将wh-从句置于句末，比如：

Itisnotyetdecidedwhowilldothatjob.第6页第6页四、if,whether引导名词从句1）yes-no型疑问从句从属连词if,whether引导名词从句是由普通疑问句或选择疑问转化而来，因此也分别被称为yes-no型疑问句从句和选择型疑问从句，其功效和wh-从句功效相同，比如：主语：Whethertheplanisfeasibleremainstobeproved.宾语：Letusknowwhether/ifyoucanfinishthearticlebeforeFriday.表语：Thepointiswhetherweshouldlendhimthemoney.同位语：Theyareinvestigatingthequestionwhetherthemanistrustworthy.形容词宾语：

She'sdoubtfulwhetherweshallbeabletocome.介词宾语：

Iworryaboutwhetherhecanpasstheexams.2）选择性疑问从句选择性疑问从句由关联词if/whether…or或whether…ornot构成,如:Pleasetellmewhether/iftheyareSwedishorDanish.Idon'tcarewhetheryouliketheplanornot.第7页第7页五、否定转移1)将think,believe,suppose,expect,fancy,imagine等动词后面宾语从句否认词转移到主句中，即主句谓语动词用否认式，而从句谓语动词用必定式。

Idon'tthinkIknowyou.我想我并不结识你。

Idon'tbelievehewillcome.我相信他不回来。注意：若谓语动词为hope,宾语从句中否认词不能转移。

Ihopeyouweren'till.我想你没有生病吧。2)将seem,appear等后从句否认转移到前面。

Itdoesn'tseemthattheyknowwheretogo.

Itdoesn'tappearthatwe'llhaveasunnydaytomorrow.3)有时将动名词，介词短语或整个从句否认转变为对谓语动词否认。Idon'trememberhavingeverseensuchaman.我记得从未见过这样一个人。(not否认动名词短语having…)4)有时状语或状语从句中否认能够转移到谓语动词前。Theantisnotgatheringthisforitselfalone.(否认状语)第8页第8页1.Itnowappears______theyareinneedofhelp.A.that B.which C.whatD.how2.Itisgoodnews______theywillarriveinafewdays.A.whichB.what C.thatD.how3.It______Joedrivesbadly.A.thoughtthat B.thinksthatC.isthoughtwhich D.isthoughtthat4.It______heislateforclass.A.maythat B.mightthatC.maybethat D.mightbewhat5.Thisis______shewasborn.A.whereB.which C.thatD.what6.Thequestionis______wecan’tgotheretoday.A.thatB.what C.whichD.when第9页第9页7.Thequestionis______itisworthdoing.A.ifB.whether C.whichD.what8.Thereasonhehasmadesuchgreatprogressis_______hehasneverwastedhistime.A.becauseB.why C.thatD.what9.Mysuggestionis______weshouldturnthelandintoricefields.A.whatB.that C.whichD.where10.Hisproposalisthatthedam______atthefootofthemountain.A.buildB.willbuild C.bebuiltD.willbebuilt11.Myadviceisthathe______regularhouse.A.keepB.wouldkeep C.keepsD.kept12._____
