高一英语名词性从句

高三英语总复习语法系列训练宝安高级中学高三英语备课组名词性从句一、引导名词性从句的连接词在句子中起名词作用的句子叫名词从句(NounClauses）。名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，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。引导名词性从句的连接词可分为三类：连接词：that,whether,if(不充当从句的任何成分）连接代词：what,whatever,who,whoever,whom,whose,which.连接副词：when,where,how,why不可省略的连词：1.介词后的连词2.引导主语从句和同位语从句的连词不可省略。Thatshewaschosenmadeusveryhappy.Weheardthenewsthatourteamhadwon.whether与if均为“是否”的意思。但在下列情况下，whether不能被if所取代：1.whether引导主语从句（包括从句在句首的位置）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可以引导从句作介词的宾语，而if则不能，如：I’mnotinterestedinwhetherthey’llgoornot.Itdependsonwhetherwehavegotenoughmoney.4.whether可以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’llattendthemeetingisessential.★大部分连接词引导的主语从句都可置于句末，用it充当形式主语。Itisnotimportantwhowillgo.二、名词性that-从句1）由从属连词that引导的从句叫做名词性that-从句。that只起连接主句和从句的作用，在从句中不担任任何成分，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，例如：主语：Thatheisstillaliveissheerluck.宾语：JohnsaidthathewasleavingforLondononWednesday.表语：Thefactisthathehasnotbeenseenrecently.同位语：Thefactthathehasnotbeenseenrecentlydisturbseveryoneinhisoffice.形容词宾语：Iamgladthatyouaresatisfiedwithyourjob.2）that-从句作主语通常用it作先行词，而将that-从句置于句末，例如：Itisquiteclearthatthewholeprojectisdoomedtofailure.It'sapitythatyoushouldhavetoleave.a.It+be+形容词+that-从句Itisnecessarythat…有必要……Itisimportantthat…重要的是……Itisobviousthat…很明显……b.It+be+-ed分词+that-从句Itisbelievedthat…人们相信……Itisknowntoallthat…从所周知……Ithasbeendecidedthat…已决定……c.It+be+名词+that-从句Itiscommonknowledgethat………是常识Itisasurprisethat…令人惊奇的是……Itisafactthat…事实是……d.It+不及物动词+that-分句Itappearsthat…似乎……Ithappensthat…碰巧……Itoccurredtomethat…我突然想起……用it作形式主语的that-从句有以下四种不同的搭配关系：三、名词性wh-从句1）由wh-词引导的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-从句的语法功能除了和that-从句一样外，还可充当介词宾语、宾语补语和间接宾语等，例如：主语：Howthebookwillselldependsonitsauthor.直接宾语：Inone'sownhomeonecandowhatonelikes.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-从句作主语也常用先行词it做形式主语，而将wh-从句置于句末，例如：Itisnotyetdecidedwhowilldothatjob.四、if,whether引导的名词从句1）yes-no型疑问从句从属连词if,whether引导的名词从句是由一般疑问句或选择疑问转化而来的，因此也分别被称为yes-no型疑问句从句和选择型疑问从句，其功能和wh-从句的功能相同，例如：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whethe…ornot构成,如：Pleasetellmewhether/iftheyareSwedishorDanish.Idon'tcarewhetheryouliketheplanornot.五、否定转移1)将think,believe,suppose,expect,fancy,imagine等动词后面宾语从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。Idon'tthinkIknowyou.我想我并不认识你。Idon'tbelievehewillcome.我相信他不回来。注意：若谓语动词为hope,宾语从句中的否定词不能转移。Ihopeyouweren'till.我想你没有生病吧。2)将seem,appear等后的从句的否定转移到前面。Itdoesn'tseemthattheyknowwheretogo.Itdoesn'tappearthatwe'llhaveasunnydaytomorrow.3)有时将动名词，介词短语或整个从句的否定转变为对谓语动词的否定。Idon'trememberhavingeverseensuchaman.我记得从未见过这样一个人。(not否定动名词短语having…)4)有时状语或状语从句中否定可以转移到谓语动词前。Theantisnotgatheringthisforitselfalone.(否定状语)1.Itnowappears______theyareinneedofhelp.A.thatB.whichC.whatD.how2.Itisgoodnews______theywillarriveinafewdays.A.whichB.whatC.thatD.how3.It______Joedrivesbadly.A.thoughtthatB.thinksthatC.isthoughtthatD.isthoughtthat4.It______heislateforclass.A.maythatB.mightthatC.maybethatD.mightbewhat5.Thisis______shewasborn.A.whereB.whichC.thatD.what6.Thequestionis______wecan’tgotheretoday.A.thatB.whatC.whichD.when7.Thequestionis______itisworthdoing.A.ifB.whetherC.whichD.what8.Thereasonhehasmadesuchgreatprogressis_______hehasneverwastedhistime.A.becauseB.whyC.thatD.what9.Mysuggestionis______weshouldturnthelandintoricefields.A.whatB.thatC.whichD.where10.Hisproposalisthatthedam______atthefootofthemountain.A.buildB.willbuildC.bebuiltD.willbebuilt11.Myadviceisthathe______regularhouse.A.keepB.wouldkeepC.keepsD.kept12.______knowsthetruthwilltellyouaboutit.A.WhothatB.WhoeverC.WhomthatD.Thatwho13.Weallknowthetruth_____theearthgoesroundthesun.A.thatB.whichC.whatD.whether14.Weheardthenews______ourteamhadwon.A.whichB.thatC.whatD.where15.Theproblem______itisrightorwronghasnotyetbeendecided.A.whichB.thatC.whetherD.if16.Youmustdowell______theteacherasksyoutodo.A.whichB.whatC.thatD.whereGood-bye!；林内热水器维修林内热水器维修电话林内热水器官网在惜月的房里？真如惜月说的那样，极为不凑巧地撞见咯？还是说韵音知道咯他经常来惜月这里，借与惜月关系交好之便，故意出现在他的面前，以期引起他的注意？这各猜测刚壹出现在脑海，就被他立即否定掉咯。虽然他与韵音的接触不多，但韵音是啥啊人，他还是非常清楚的：老实巴交、与世无争、企保平安，这是韵音壹贯的性情和处事原则。要说刚刚突发的情况是韵音为咯争宠使出的手段，那么她嫁进王府的七年时间里，有无数的机会，她为啥啊壹次都没有使用呢？难道今天她就算准咯爷要去惜月那里，又算准咯爷中途离开，再算准咯在她的院门口上演壹场苦肉计？真若是这样，韵音简直就是神仙咯！对惜月，他是心存愧疚；对韵音，他是满怀同情。惜月虽然不对他的胃口，但惜月性情活泼、聪明伶俐、八面玲珑，不管他对她如何，她都能在这王府里如鱼得水，活得有滋有味。韵音就完全不同咯。韵音也不对他的胃口，可是韵音生性木吶，老实本分，同时
