高三复习虚拟语气的一个很好的课件

SubjunctiveMood1.英语动词有三种语气，陈述语气，祈使语气和虚拟语气。2.定义：用来表示说的话不是事实，或者是不太可能发生的情况，而是一种愿望，建议，假设的语气叫虚拟语气。一、虚拟语气在条件状语从句中的用法条件从句If从句的谓语形式主句的谓语形式现在过去未来did/werehaddonewould/could/should/might+V.(原)would/could/should/might+have+p.p.1.did/were2.shoulddo3.weretodowould/could/should/might+V.(原)3.IfI

(are)abird.IwishI

(make)suchamistake.Wewishourparents

(punish)us.二、虚拟语气特殊句型：

wish

+宾语从句现在：过去：未来：过去时(did/were)过去完成时(haddone)would/could/might+V.shouldwouldn’tpunishwerehadn’tmade(未来)(现在)(过去)2.wouldratherthat--现在：过去：未来：Iwouldratheryou

(pay)menow.Iwouldratheryou(go),too.Don’tcome.Iwouldratheryou

(come)tomorrow.过去时过去时过去完成时(未来)paid(现在)hadgone(过去)

came3.asif/though+从句现在：过去：将来：过去时过去完成时她爱这孩子仿佛是她自己的儿子一样天气看来象春天一样我记得整个事情仿佛就发生在昨天would\could\might+动词原形Shelovesthebabyasifitwereherownson.Itseemsasifitwerespring.Irememberthewholethingasifithadhappenedyesterday.Helooksasifhe

drunk.

Itlooksasifit

rain.

注意:若asif从句所表达的意思是真实的要用陈述语气.Itlooksasifit(benot)cleanenoughtobathehere.Lookattheclouds!Itlooksasifit

(be)goingtorain.mightwereisisn’t4.It’s(about/high)time+that--should+V.过去时你该走了。我们该睡觉了。It’shightimethatyouwent.It’shightimethatyoushouldgo.It’s(about)timethatwewent

tobed.It’stimethatweshouldgotobed.5.表示要求，命令，建议的虚拟语气。宾语从句。常见动词：一个坚持：insist两个命令：order,command

三个建议：advise,suggest,propose四个要求：demand,require,request,desire(ask)这些动词后面的宾语从句要使用虚拟语气用法。即从句中的动词使用should+动词原形，或者将should省略。我们建议Tom去休息一下。他坚决要求我到场。国王命令囚犯明天要实施死刑。他们要求我们派他们去那儿工作。WesuggestedthatTom(should)havearest.HeinsistedthatI(should)bepresent.Thekingorderedthattheprisoners(should)bekilledthenextday.Theyrequestedthatwe(should)sendthemtoworkthere.注意:suggestinsist不用虚拟语气的情况

她的表情表明她生气了那女孩坚持说她几天前已把钱还给我了1.Herexpressionsuggestedthatshewasangry.2.Thegirlinsistedshegavemethemoneytheotherday.以上动词相应的名词构成的名词性从句（包括主语从句，表语从句和同位语）也要使用虚拟语气。从句中的动词形式一样。

order,advice,suggestion,proposal,demand,request,desireMydemandisthatshe

(come)toseemeonceaweek.Allofusarefortheadvicethatthechemicalworks

(be)closeddown.Weallagreedtothesuggestionthatwe____________(go)toBeijingforsightseeing.Theproposalthatwe

(go)outforapicnicwaswarmlywelcomed.(should)goshouldcomeshouldbe(should)go6.without和butfor构成虚拟。(butfor要不是)Withoutsunlight,people’slife

(be)differentfromtoday.Butforyourhelp,I_________________(notfinish)thework.Withoutyourhelp,I

(fail).Butforwater,it

(be)impossibletoliveinthedesert._wouldn’t

havefinishedwouldbewouldhavefailedwouldbe7有时为了表达需要,并不总是出现if引导的条件句,而通过其他手段来代替条件句.1.Iwasillthatday.0therwise,I_______________________(takepartin)thesportsmeet.2.I

(give)youmorehelp,butIwastoobusy.3.Amanwhostoppeddrinking_____

(are)deadinsevendays._wouldhavetakenmighthavegiven

7.Ifonly…(要是…就好了)

IfonlyI

(know)hisname!Ifonlywe

(follow)youradvice!IfonlyI

(see)himagain!要是我们的父母能和我们住在一起就好了。要是我没错过火车就好了！Ifonlyourparentscouldlivewithus!IfonlyIhadn’tmissedthetrain!

stillbetter.如果你听了老师的建议的话，你现在就不会在医院里了．Ifyou
