虚拟语气详细讲解及练习课件

TheSubjunctiveMood

虚拟语气高考对虚拟语气的考查重点在于：1．与事实相反的三种情况；2．虚拟语气在从句中的应用；3．含蓄条件句构成的虚拟语气虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设或推测等。IfIwereyou,IshouldstudyEnglish.Iwishyoucouldgowithme.Mayyousucceed!1.与现在事实相反if从句-----过去式(be通常用were)，主句----should(would,could,might)+动词原形”：IfIknewhernumberIcouldringherup.

Ifhewerefree,hewouldhelpus.

Ifhestudiedatthisschool,hewouldknowyouwell.Should用于第一三人称would表示结果，might表示可能性，could表示能力、允许或可能性1.要是你再试一试，你就会成功的。

Ifyoutriedagainyouwouldsucceed。2，如果我是只鸟，我就能在天上飞了。

Ifitrainedtomorrow,ourpicnicwouldbeputoff.Ifheweretocomehere,hewouldtellusaboutit.IfheshouldgotoQingHuaUniversity,hewouldmakefulluseofhistime.3，与过去事实相反if从句——haddone主句——should/would/could/might+havedoneIfIhadleftsooner，Iwouldhavebeenontime.2)要是我们当时早点找到他的话，我们就可以救活他Ifwehadfoundhimearlierwecouldhavesavedhislife.

注意：1，条件从句的谓语动词为be时，不管其主语为单数还是复数通常都用were，但在口语或非正式文体中的单数第一人称和第三人称后，也可用was，不过在IfIwereyou这样的表达中，通常还是以用were为宜。Ifhehadlearntaboutcomputers,wewouldhavehiredhimtoworkhere.Hadhelearntaboutcomputers,wewouldhavehiredhimtoworkhere.Ifshewerehere,shewouldagreewithusWereshehere,shewouldagreewithus含蓄虚拟语气有时假设的情况并不用条件从句表达，而是由otherwise,but,or,without,butfor等来引导。Iwasillthatday.Otherwise,Iwouldhavetakenpartinthesportsmeeting.(副词)我那天病了。否则，我就参加运动会了。Hetelephonedtoinformmeofyourbirthday,orIwouldhaveknownnothingaboutit.(连词)他打电话告诉我你的生日，否则我对此一无所知。Withoutyourhelp,wecouldn'thavefinishedtheworkaheadoftime.＝

Butforyourhelp,wecouldn'thavefinishedtheworkaheadoftime.＝

Ifithadnotbeenforyourhelp,wecouldn'thavefinishedtheworkaheadoftime.＝

Haditnotbeenforyourhelp,wecouldn'thavefinishedtheworkaheadoftime.没有你的帮助，我们不可能提前完成这项工作。如：Withoutyourhelp，Iwouldhavefailed.没有你的帮助，我当时就会失败的。Butforthestorm，weshouldhavearrivedearlier.要不是暴雨，我们还会早到一些。Withherhelp，Iwoulddotheexperimentbetter.在她的帮助下，我就会把实验做得更好。Onlyforyourhelp，Iwouldhavefailed.若不是你的帮助，我早就失败了。虚拟语气在从句的用法一，wish后的宾语从句1.与现在事实相反------一般过去时及（be的过去式为were）2.与过去事实相反-------过去完成时:（had+过去分词）3.与将来事实相反--------would/could+动词原形1.Iwish_____________________________(他再试一次)hewouldtryagain2.Iwish____________________(和你一样年轻)Iwereasyoungasyou3.Iwish__________________________(我看过这部电影)Ihadseenthatfilm4.Iwish_____________________________(我将来当个医生)Iwouldbecomeadoctor注意：insist作“力言、坚持说”解时，宾语从句不用虚拟语气，只有当insist作“坚持(应该)”“坚持(要求)”解时宾语从句才用虚拟语气。如：Heinsistedthatshewasinnocentandthatshe(should)besetfree.三，Itissuggested/requested/desired/proposed/….that…后接主语从句时advice,desire,order,plan,,recommendation,request,requirement,suggestion,wish充当句子的主语后接同位语从句，或表语从句时从句中都用(should)+do四，asif(though)从句用虚拟语气与现在事实相反——一般过去时；与过去事实相反——过去完成时；表示将来的可能性不大——would(might,could)+动词原形：Iloveyouasif_____________(你是我儿子)youweremyson.

Theytalkedasif__________________________(以前见过面)theyhadmeteachotherbeforeTheyarehappyasif_________________________(他们要去月球了)theywouldgotomoon五，Itis(about/high)timethat到了…..的时候了Itistimethat+过去时Itwastimethat+过去完成时六,wouldrather宁愿，用法同wish,asif七，ifonly要是…就好了，用法同上5.Ifitwerenot/hadnotbeenfor…
