虚拟语气(一)If引导的非真实虚拟条件句语气英语的动词一般可带有三种不同的语气：陈述语气，祈使语气和虚拟语气。不同的语气用动词的不同形式来表示。•虚拟语气是一种特殊的动词形式，•一是用来表示说话人所说的话不是一个事实，而是一种假设、猜测、怀疑等(常用在条件状语从句中或让步状语从句中)；•一是表示说话人的愿望、要求、命令、建议等(常用在名词性从句中)。•简言之，即：不是事实或不大可能发生的事情，就用虚拟语气来表述虚拟语气的概念与现在的事实相反与将来的事实相反与过去的事实相反时间if从句谓语动词主句谓语动词haddonedid/were1.weretodo2.shoulddowould/should/could/mighthavedonewould/should/could/mightdowould/should/could/mightdo1.非真实条件状语从句，Ifshehadrecognizedthequeen,shewouldnothaveeatentheapple....Ifshehadnoteatentheapple,___________________________shewouldnothavedied.a.与过去事实相反If+主+haddonesth,主+would/should/could/might+havedoneIf+主+did(were),主+would/should/could/might+dob.与现在事实相反IfIwereSnowWhite,thehuntertheprinceIfSnowWhitediednow，Iwouldbethemostbeautifulwoman.IfIfollowedthequeen'sorder,thepoorSnowwhitewoulddie.IfIhadabeautifuldress,Iwouldbeabletoattendtheball.Wow!Itsuitsyouwell.Ifitwerenotsuitableforyou,youcouldn'tbetherightperson.如果我有漂亮的裙子，我就能够去参加舞会了。哇，太合脚了!如果这双鞋子不适合你，你就不可能是我要找的人。CinderellaIfIhadmagicpower,Iwould_______c.与将来事实相反的非真实条件句Ifitshouldsnowtomorrow,Iwouldmakeasnowman.如果明天下雪的话,我会堆一个雪人.If+主+shoulddo/weretodo,主+would/should/could/might+动词原形IfIwereyou,Iwouldtryitagain.在非真实条件句中，if省略，并将were,had,should放在主语前，构成倒装句式。WereIyou,Iwouldtryitagain.or,otherwise,without,butfor,but等词经常出现在含蓄虚拟条件句中。213Thankyouforyourhelp,or/otherwiseIwouldbedoingmyhouseworknow.谢谢你的帮助，不然我就在家做家务呢。Butforyourhelp,Iwouldbedoingmyhouseworknow.要不是你的帮助，我还会在做家务呢。Snowwhitewouldhavebeenkilled,butthehunterlethergo.WithoutButforyourmercy,Iwouldhavedied.要不是你的怜悯，我早已就死了。要不是butforIfitwerenotfor/Ifithadnotbeenfor白雪本来会死的，但是猎人放她走了。3.错综时间虚拟条件句错综时间虚拟条件句，即条件从句和主句时间不一致，如从句指过去，而主句指现在或将来。IfthehunterhadfollowedQueen'sorder,Icouldn'tbelivingherehappilywiththedrawfsnow.虚拟语气倒装句与过去的事实相反与现在的事实相反错综虚拟条件句与将来的事实相反含蓄虚拟条件句回顾Competition2Moon3Match4Film1ConcertChallengeOpportunity1.IfI_______________（be）you,Iwouldacceptthisjoboffer.2.IfIhadtime,I_______________(go)totheconcert.3.Ifyou_______________（arrive）alittleearlier,youwouldhavecaughtthebus.4.I_________________(buy)thecarifIhadhadenoughmoney.5.Youwouldhavesucceededifyou_______________(keepon)trying.werewouldgohadarrivedwouldhaveboughthadkeptonExercises6.Ifthecontest_______________(takeplace)tomorrow,Iwouldprobablygoandseeit.7.Iftheearth__________(have)nogravity,themoonwouldflytothesun.8.Ifshehadn'ttakenyouradvice,she_______________(make)aseriousmistake.9.Butforthemeeting,I_________________(go)homeat6:00..10.Ifhe____________（take）myadvice,he__________________（succeed）inthecompetition.shouldtakeplacehadwouldhavemadehadtakenwouldhavesucceededwouldhavegone11.Ifpeople_______(drive)moreslowly,therewouldn’tbesomanyaccidents.12.Hadyouworkedcarefully,you_________________(notmake)somanymistakes.13.Ifit___________（rain）tomorrow,thefootballmatch________________（putoff）.14.Ifyou____________(follow)myadvice,you______________(good)now.15.Ifyou____________(study)theproblemcarefully,you______________(notfind)difficultynow.drovewouldn'thavemadeshouldrainwouldbeputoffhadfollowedwouldbebetterhadstudiedwouldnotfind1.IfIwasyou,Iwouldrunfaster.2.IfIlivenearmyoffice,Iwouldwalktowork.3.Iknownothingaboutthefilm.IfIknewaboutit,Iwilltellyou.4.Ifsheworkedhardenough,shewouldhavepassedtheEnglishexam.werelivedwouldhad5.Ifyouaskedhimyesterday,youwouldknowwhattodonow.6.Ifitwerenotforthefactthathecouldn’tsing,Iwouldinvitehimtotheparty.7.Shouldtheweatherfine,wemightgoonatrip.8.Shewasverybusyyesterday,otherwiseshewouldcometothemeeting.hadcan’tbehaveThankyou
