1宾语从句一、宾语从句的定义:宾语从句是一种名词性从句,在句中作及物动词的宾语,或介词的宾语,或形容词的宾语。Iknowhim.Iknowwhoheis.主语谓语宾语主语谓语连词从句主语从句谓语主句宾语从句宾语:位于谓语动词或者介词后:Iknowhim.Doyouhavethetime?Ithink(that)sheisbeautiful.Whydon’tyoupayattentiontome?宾语从句的概念:从句在复合句中作宾语的名词性从句,通常放在主句谓语动词(及物动词)或介词、形容词之后。WeknowMrGreenteachesEnglish.Sheaskediftheseanswerswereright.二、宾语从句分类:根据引导宾语从句的不同连词,宾语从句可分为三类:1.由that引导的宾语从句。That只有语法作用,没有实在的意义,在口语和非正式文体中可以省略。例如:Hesaid(that)hewantedtostayathome.Shedoesn’tknow(that)sheisseriouslyill.Iamsure(that)hewillsucceed.that的省略:e.g.Iguess(that)somebodyelsehasborrowedit.注意:当主句谓语动词带有两个或两个以上宾语从句时,可以省略第一个that,其他不能省略。eg.Ibelieve(that)youhavedoneyourbestandthatthingswillgetbetter.2.由连接代词who,whom,whose,what,which和连接副词when,where,why,how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如:Doyouknowwho(whom)theyarewaitingfoe?Heaskedwhosehandwritingwasthebest.CanyoutellmewheretheNo.3busstopis?Idon’tknowwhythetrainislate.3.由if或whether引导的宾语从句。if/whether“是否”,说明对陈述的事物不明确或不清楚。常用在ask,wonder,can(could)youtellme表示疑问不确定意义的词之后;从句句意完整,不缺成分。Iwanttoknowif(whether)hewillgototheparkwithus.2Askhimwhether(if)hecancome.Iwonderwhetheritisgoingtorainornot.Couldyoutellmewhether(if)MrLiliveshere?只用whether的情况:1.在引导主语从句、表语从句、引导同位语从句时:主语从句:Whetheritistrueremainsaquestion.Whetherheisrightorwrongisaquestion.表语从句:Thequestioniswhetheritistrue.(为了强调宾语部分,也可把从句提在主句前。WhetherhewillcomeIamnotsure.)Thequestionwhetherhewillacceptitconfusesus.2.用在动词不定式之前时(whethertodosth.):Theyaskedmewhethertogoskating.Idon’tknowwhethertogothereatonce.3.当与ornot连用,或or提出两种选择时:Idon’tknowwhetherhe’sfreeornot.MaryaskedwhetherIwasdoingmyhomeworkornot.Tellmewhetheryou’dliketogoshoppingortidytheroom.4.在介词或discuss后面:I’mthinkingofwhetherweshouldgofishing.Wediscussedwhetherweshouldclosetheshop.注意:只能用if不能用whether的情况1.引导条件状语从句Ifherunsfast,he’llgetthereontime.I’llgotoseeyouifIhavetime.2.引导否定的宾语从句Tellmeifitisnotgoingtorain,please.if/whether用法巧记:两个“是否”并不难,一般情况可代换。下列情况用whether,主表不定式or(not)。作为讨论介词宾,此时if不可跟。还有一点也得编,whether从句可提前。引导条件表“如果”,再也不可用whether。宾语从句若否定,whether一词不可用。练习:选择if/whether。1.Iaskedher__________shehadabike.2.We’reworriedabout________heissafe.3.Iwonder___________heiswell.4.Idon’tknow________ornotheiswell.5.Idon’tknow_______togo.三、宾语从句的语序:宾语从句的语序用陈述语序:主句+连接词+主语+谓语+其他成分;即:助动词不能放在主语前面。例如:Iwanttoknowif(whether)helivesthere.Heaskedmewhether(if)Icouldhelphim.注:当从句的原句为以下句子以及what,who作主语时,语序不变:3What’swrong?What’sthematter?What’shappening?Whoisoverthere?Idon’tknowwhat’sthematter.Canyoutellmewhoisoverthere?Canyoutellmewhoheis?注意:否定前移若主句谓语动词为think,guess,imagine,suppose,believe等其后的宾语从句若含有否定意义,一般要把否定词转移到主句谓语上,从句谓语用肯定式;其反意疑问句,疑问从句。主句是I/Wethink/suppose/guess/believe等时,从句中的否定习惯上要转移到主句中。如:我认为鸡不会游泳。误:IthinkTomcannotswim.正:Idon’tthinkTomcanswim.此外,上述情况在变成反意疑问句时,附加疑问句要看从句,如果主句的主语不是第一人称,则附加疑问句要看主句。试比较:Ithinkheiswrong,isn’the?Hethinksheisright,doesn’the?(1).Idon’tthinkheisright,__________?A.isn’theB.isheC.doID.don’tI(2).Hebelievessheisright,__________?A.doesn’theB.doesheC.issheD.isn’tshe否定前移及反意疑问句形式巧记法:我认为猜想有假不可信,提问宾从构反问。从句若表否定意,否定词语要前移。Idon'tthinkthisdressfitsyouwell,doesit?我认为这件衣服不适合你穿,是吗?Idon'tbelieveyouwillfinishtheworktoday,willyou?我认为你今天无法完成工作,是吗?四、时态1.主句用现在时或将来时,从句可用任何时态,根据实际情况而定。Iknowheliveshere.Iknowhelivedheretenyearsago.Ihaveheardthathewillcometomorrow.2.如果主句是过去的时态(一般过去时,过去进行时),从句的时态一定要用相对应的过去的某种时态(一般过去时,过去进行时,过去将来时,过去完成时)Iknewwholivedthere.Isawshewastalkingwithhermother.Heaskedwhetherhisfatherwouldcomebackthenextday.Hesaidthathehadseenthemovie.3.从句说明的是一般真理、客观事实、自然现象时,仍用一般现在时。Dadtoldusthatitisbettertodothantosay.Hetoldtheboythatthreeandthreeissix.4Hetoldmetheearthmovesaroundthesun.Mr.Litoldmethesunrisesintheeast.练习:1.Theradiosaysit_______cloudytomorrow.(be)2.Theheadmasterhopeseverything______well.(go)3.Ihearthey__________(return)italready.4.Hesaidthatthey_________membersofthePartysince1948.(be)5.Ourteachertoldusinclassthesun_______intheeast.(rise)宾语从句巧记法:宾语从句要注意,时态引导词和语序。1.时态问题时态问题看主句,现在时态可随意。过去时态用过去,客观情况要注意,主过从现要切记。2.引导词问题引导词,并不难,主句含义最关键。主表肯定意完整,that常用也可省。主表疑问不确定,另类词,要使用。从句句意若完整,if/whether不可省。从句若是缺成分,特殊(疑)问词来过问。3.语序问题还有一项是语序,陈述语序要切记。如何对它来判断,助动莫放主语前重点:1.从句中的语序为陈述语序;Doyouknowhowoldisshe?(应改为:…howoldsheis)2.从句中的时态与主句时态前后呼应。Shedidn’ttellmewhenshewillcome.(应改为:…whenshewouldcome)3.转换:由连接代词和连接副词引导的宾语从句可用疑问代词和疑问副词+动词不定式替代,进行句型上的转换。I’venoideawhatwe’regoingtodonext.=I’venoideawhattodonext.CouldyoutellmehowIcangettothepostoffice?=Couldyoutellmehowtogettothepostoffice?难点:1.宾语从句中的It可运用形式宾语it代替的宾语从句①动词find,feel,consider,make,believe等后面有宾语补足语的时候,则需要用it做形式宾语而将that宾语从句后置.5Ithinkitnecessarythatwetakeplentyofhotwatereveryday.IfeelitapitythatIhaven’tbeentotheget-together.我没去聚会,感觉非常遗憾.IhavemadeitarulethatIkeepdiaries.Ithinkitnousecrying.②有些动词带宾语从句时需要在宾语与从句前加itIhateitwhentheyarewiththeirmouthsfulloffood.PleaseseetoitthatthedoorisclosedDon'ttakeitforgrantedthatwehelpyou.Iwouldappreciateitifyoucouldhelpme.(1).Ifind_____importantthatwepracticeEnglisheveryday.A.itB.thisC.thatD.what(2).Youcan’timagine____whentheyreceivedthenicegift.A.howtheywereexcitedB.howexcitedtheywereC.howexcitedweretheyD.theywerehowexcited2.宾语从句中的虚拟1)suggest,order,insist,propose,宾语从句表示的是一种虚拟语气,s
