初中宾语从句课件(共21张PPT)

引导词语序时态人称动词变化闯关将两个简单句联结成一个宾语从句，一般要用到三种引导词：一、that用于引导陈述句。在口语或非正式场合可以剩去。二、if,whether用于引导一般疑问句。三、连接代词和连接副词what,which,when,where等作引导词（如果从句是特殊疑问句）。比较练习多数情况下if,whether可以通用。下列三种情况下只能用whether，而不能用if。1.从句表达的是含有选择意义的疑问句。(含有ornot时)2.用于介词之后。3.whether引导的从句可以转换成简单句即可以构成“whether+动词不定式”的形式，而if引导的从句不可以。I’mthinkingaboutwhetherIhavemadeanothermistake.Idon’tknowwhethertojointheclub.Pleasetellmewhetherornotyouagreewiththeteacher.1.–Becareful!Don’tbreakthebottles.Doyouhear___Isaid,David?A.whatB.thatC.whyD.if2.Canyoutellme___sheiswaitingfor?A.whyB.whoseC.whomD.which3.-Idon’tknow___MrGreenwillcometoseeus.-HewillhelpuswithourEnglish.A.whyB.whenC.howD.where4.Mr.Greensays____theywillgobacktoEngland.A.whoB.thatC.whichD.where5.Idon’tknow__itwillraintomorrow.A.thatB.ifC.whyD.what无论从句是何种句式，放到主句后成为从句时，一律要用陈述语气。如：Whereisthelibrary?Idon’tknow.Idon’tknowwherethelibraryis?Willhecometomorrow?I’mnotsure.I’mnotsureif/whetherhewillcome.要特别注意几个特殊疑问句作主语的情况：如：What’swrongwithyou?Iwanttoknow.Iwanttoknowwhatiswrongwithyou?Whoisknockingatthedoor?Letmesee.Letmeseewhoisknockingatthedoor.Whichisthewaytotherailwaystation?Canyoushowme?Canyoushowmewhichisthewaytotherailwaystation?1.Heaskedme______.A.whodidkickthefirstgoalintheWorldCupB.whenwastheAPECmeetingheldC.whenChinabecameamemberoftheWTOD.whenwillthe2008Olympicsbeheld2.Mumaskedme___thismorning.A.whatthematterisB.whatiswrongC.whatwasthematterD.whatwrongwas含宾语从句的主从复合句的主句谓语动词时态一般有两种：现在时和过去时。若主句动词是现在时，从句依据需要用任何时态；若主句动词是过去时，则要将从句变成相应的过去时态。主句从句+含有宾语从句的主从复合句现在时根据需要用任意时态过去时一般现在时现在进行时一般将来时现在完成时一般过去时过去进行时过去将来时过去完成时例句如：Hetoldme,“Tomhasbeenthere.”HetoldmethatTomhadbeenthere.“Areyoufreethisafternoon?”Heaskedme.HeaskedmeifIwasfreethisafternoon.有一些特殊场合，尽管主句谓语动词是过去时，从句仍保持原来的时态1从句表达的是客观事实、科学真理、现在的习惯动作及格言。2从句表达的动作或状态仍在继续。3当主句中的情态动词could,would,表示委婉语气时。Theteachertoldusthatthesungoesaroundtheearth.Hesaidheisfortyyearsold.Wouldyoupleasetellusifyouwillgiveusalecture?1.Hetoldusthesun___biggerthanthemoon.A.wasB.isC.areD.were2.Theteachertoldusthatlight___muchfasterthansound.A.travelsB.traveledC.wasD.willbe3.UncleWangtoldusNonews___goodnews.A.wasB.isC.areD.were主从复合句中的人称要保持一致。如：Hetoldme,”MyfatherwillhelpyouwithyourEnglish.”HetoldmethathisfatherwouldhelpmewithmyEnglish.1、Doyouknow_____?Nextyear.A.whenhecamehereB.whendidhecomehereC.whenhewillcomehereD.whenwillhecomehereC2.Iwanttoknow_________.A.Whatishisname.B.what’shisnameC.ThathisnameisD.whathisnameisD3.I‘msorry,Ireallydon’tknow___theclock.•tomendB.howshouldImendC.WhattomendD.howtomendD4.Jimdoesn’tunderstand_________.A.WhichthewaytothemuseumisB.WhyhiswifealwaysgoesshoppingC.WhatisthewaytothemuseumD.WhydoesshealwaysgoshoppingB你真棒！学习宾从三注意，时态语序和连词。时态主从要呼应：主句若为现在时，从句时态随句意；主句若为过去时，从句时态变过去；宾从若是表真理，时态不变无质疑。语序要用陈述序，切莫照搬疑问句。That连接陈述句，省与不省要注意。从句若表是否时，if/whether要慎记。特殊问句作宾语，仍用原来疑问词。三个问题需记牢，切莫丢东忘了西。1.----Couldyoupleasetellme____？-----It’snexttothepostofficeA.whereisthesupermarkerB.wherethesupermakerisC.wherewasthesupermakerD.wherethesupermakerwas2.Iwanttoknow____thedayaftertomorrow.A.whathewilldoB.whatwillhedoC.whathedidD.whatdidhedo3.ProfessorNelsonwantedtoknow____.A.whenwouldtheconferencebeginB.whentheconferencewouldbeginC.whenwilltheconferencebeginD.whentheconferencewillbegin4.Noonecanbesure___inamillionyears.A.whatmanlookslikeB.whatwillmanlookslikeC.manwilllooklikewhatD.whatmanwilllooklike
