混合虚拟条件句课件

一、动词wish后宾语从句中的虚拟语气1．用wish表示对过去事情的遗憾。

2．用wish表示现在的祝愿和抱歉。

其句子结构为：宾语从句的谓语be为were，实义动词用过去式。eg.Iwishtheywereathomethistime.

3．用wish表示对将来事情的愿望。

其句子结构为宾语从句的谓语would/could/might+动词原形。例：IwishIcouldcometomorrow。混合虚拟条件句二条件从句结果主句与过去事实相反IfI(we,you,he,they)+haddone/beenI(we)should/wouldyouwouldhe/shewouldtheywould与现在事实相反IfI(we,you,he,they)+were/didI(we)should/wouldyouwouldhe/shewouldtheywould与将来事实相反IfI(we,you,he,they)+动词的过去式/weretodo/shoulddoI(we)should/wouldyouwouldhe/shewouldtheywould+do/be+havedone/been+do/be混合虚拟条件句1.Ifwe____now,weshouldarriveingoodtime.A.leaveB.leftC.areleavingD.toleave2.I_____whatthesewereforifIhadn’tbeentold.A.wouldn’thaveknownB.didn’tknowC.hadn’tknownD.shallhaveknown3.Ifyou_____theglass,itwouldbreak.A.dropB.droppedC.aredroppingD.haddroppedBAB混合虚拟条件句注意：1.If从句中若含有should,had

或者were，那么就可以把它们放在句首，与主语颠倒形成倒装，但动词过去式不可以与主语倒装。1).如果他在，他会来帮助我们。Werehehere,hewouldcometohelpus.2).假如你刚才在这里，你就会遇见她。Hadyoubeenherejustnow,youwouldhavemether.3).假如我明天看见他，我就会告诉他关于这一切。ShouldIseehimtomorrow,Iwouldtellhimaboutit.混合虚拟条件句2.当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为“错综时间条件句”，动词的形式要根据它所表示的时间作出相应的调整。1)如果他早点出发，他现在已到家了。Ifhehadsetoutearlier,hewouldbehomenow.2).假如你接受了我的意见，你现在就会好的多。Youwouldbemuchbetternowifyouhadtakenmyadvice.混合虚拟条件句4.IfIhadspokentohimyesterday,I___whattodonow.A.willknowB.shouldknowC.knowD.wouldhaveknown5.Youwouldbemuchbetternowifyou________myadvice.A.takeB.havetakenC.hadtakenD.tookBC混合虚拟条件句三.含蓄条件表达方法：1.介词：without,butfor2.连词：otherwise,or,but,though,once混合虚拟条件句1.用介词短语代替条件状语从句。常用的介词由with,without,butfor等。1).Whatwouldyoudowithamilliondollars?=ifyouhadamilliondollars

=ifwehadn’tgotyourhelp3).Butforrain,wewouldhavefinishedthework.

=Ifithadn’tbeenfortherain混合虚拟条件句2.含蓄条件句有时为了表达的需要，在虚拟语气中并不总是出现if引导的条件句，而通过其他手段代替条件句。1).Iwasillthatday.Otherwise,Iwouldhavetakenpartinthesportsmeet.（副词）2).Hetelephonedtoinformmeofyourbirthday,orIwouldhaveknownnothingaboutit.（连词）3).Amanwhostoppeddrinkingwaterwouldbedeadinaboutsevendays.（定语从句）4).Everythingtakenintoconsideration,theywouldhaveraisedtheiroutputquickly.（独立主格结构）混合虚拟条件句1.WithouttheCommunistPartyofChina,______NewChina.A.therewerenotB.therewouldbenoC.therewillbeD.therehadn’tbeen2.___it___forDoctorBethune,thewoundedsoldierwoundhavelosthisleftleg.A.Were;notB.Should,notbeC.Had;notbeenforD.Was;notBCHaditnotbeenfor…和Wereitnotfor要不是…话；多亏了…不然混合虚拟条件句3.I___you,butIforgotyourtelephonenumber.A.calledB.wouldhavecalledC.wascallingD.hadcalled4.---Whydidn’tyouringmeup?---Iwouldhave,butI____yourtelephonenumber.A.forgotB.hasforgottenC.wasforgettingD.hadforgottenBA混合虚拟条件句四.在一个坚持（insist）,两个命令（order,command）,三个建议（suggest,advise,propose）,四个要求(ask，demand，request,require)等动词后的宾语从句中，谓语动词用“(should)＋动词原形”，表示建议、要求、命令等。1).我建议马上动身。Isuggestthatwe(should)setoffatonce.2).学生们坚持要多上英语课。Thestudentsinsistedthatthey(should)havemoreEnglishclasses.混合虚拟条件句3.在主语＋would(had)rather＋that宾语从句中，从句谓语用过去式表示虚拟形式。我倒希望他们和我一起去。Iwouldrathertheywentwithme.混合虚拟条件句五.虚拟语气在主语从句中的用法。主语从句是It’snecessary(natural,important,strange,surprising,better,apity,nowonder)＋that时，谓语的虚拟形式用（should）＋原形动词或should＋have＋过去分词来表示。1).高中学生掌握一门外语很有必要。Itisnecessarythatahighschoolstudentshouldmasteraforeignlanguage.2).很遗憾他居然没有在。Itisapitythatheshouldbeabsenttoday.3).我们说话要有礼貌，这是很重要的。Itisimportantthatweshouldspeakpolitely.注意：有些过去分词可以当形容词使用，在主语从句中要用虚拟语气，常见的有：desired,demanded,requested,suggested,required等。混合虚拟条件句六.虚拟语气在表语从句和同位语从句的用法。在suggestion,proposal,order,plan,idea,request,advice等名词后的表语从句和同位语从句中要用虚拟语气。其构成是“should＋动词原形”。Myideaisthatweshouldthinkitoverbeforeacceptingit.WeallagreedtohissuggestionthatweshouldgotoDalianforsightseeing.混合虚拟条件句七、在Itis(high)time(that)…的句型中，定语从句的虚拟形式常用过去式或should＋动词原形（should不能省略），表示“现在该……”我们该走了。Itistimeweleft.八、ifonly…表示一种假设情况，意思是“要是······就好了”，相当于主语＋wish。1).要是今天是星期天就好了。IfonlyitwereSundaytoday.2).要是他幽默点就好了。Ifonlyhehadasenseofhumor.混合虚拟条件句九、由asif(asthough)或eventhough(eventhough)引导的状语从句表示比较或方式时，从句谓语形式为动词的过去式（be用were）或“had＋过去分词”。他那样对待我，好像我是陌生人似的。HetreatsmeasifIwereastranger.她谈论那部影片，就好像她确实看过一样。Shetalkedaboutthefilmasifshehadreallyseenit.注意：如果表示的事情可能会发生，那么方式状语从句中的谓语动词可用陈述语气。混合虚拟条件句十、虚拟语气用在含有Ifitwerenotfor或Ifithadnotbeenfor条件句中。1).Ifitwerenotfortherain,thecropswoulddie.2).Ifithadnotbeenforyourhelp,wecoul
