高三英語虛擬語氣經(jīng)典講解

1.英語動(dòng)詞有三種語氣，陳述語氣，祈使語氣和虛擬語氣.2.

定義：用來表示說的話不是事實(shí)，或者是不可能發(fā)生或可能性比較小的情況，而是一種愿望，建議，假設(shè)的語氣叫虛擬語氣。一、虛擬語氣定義.二、虛擬語氣的考點(diǎn)

1、一般條件句中虛擬語氣的用法；2、條件句中虛擬語氣的倒裝；3、名詞性從句中虛擬語氣的用法；4、幾種特殊結(jié)構(gòu)中虛擬語氣用法；5、虛擬語氣與陳述語氣的判定。.1、一般條件句中的虛擬語氣時(shí)間If條件句主句過去haddonewouldshould+havedonesthcouldmight現(xiàn)在助動(dòng)詞be用were實(shí)義動(dòng)詞do用did

wouldshould+dosthcouldmight將來did/wereshoulddoweretodowouldshould+dosthcouldMight.1.IfIhadHIV,IwouldknowbecauseIwouldfeelsick.2.IfIwere

you,IwouldgiveAIDSpatientahug.3.IfIhadtakenyouradvice,Iwouldn’thavemadeamistake.4.Ifhehadbeenthere,itwouldn’thavehappened.與現(xiàn)在事實(shí)相反與過去事實(shí)相反.5.Ifitshouldraintomorrow,theywouldn’tgoforanouting.6.Ithinkwecoulddoit,ifweplanneditproperlyandcouldborrowthetools.7.Ifweweretohavethreedaysoff,wewouldenjoyaveryhappylife.與未來事實(shí)相反.IfIwereyou,I____buythehouserightnow.A.won’tB.don’tC.wouldn’tD.can’t2._____morecareful,hisshipwouldnothavesunk.A.IfthecaptainwereB.IfthecaptainhadbeenC.ShouldthecaptainbeD.Ifthecaptainwouldhavebeen3.Ifhe____metomorrow,IwouldlethimknowA.shouldcallB.shouldnothavebeenableC.werenotableD.arenotableBCA.2、條件句中虛擬語氣的倒裝；

假設(shè)條件虛擬倒裝。條件從句中含有

should，were，had三個(gè)助動(dòng)詞并且放在句首時(shí)，可以把if省略。IfIwereyou,Iwouldgiveitup.WereIyou,Iwouldgiveitup.IfIhadhadtime,Iwouldhaverunroundthatlakeagain.HadIhadtime,Iwouldhaverunroundthatlakeagain.Ifthereshouldbeaflood,whatshouldwedo?aflood,whatshouldwedo?Shoultherebe.3.名詞性從句的虛擬語氣。主要是表示命令、要求、建議的虛擬語氣。賓語從句。常見動(dòng)詞：一個(gè)堅(jiān)持：insist兩個(gè)命令：order,command

三個(gè)建議：advise,suggest,propose五個(gè)要求：demand,require,request,desireask

這些動(dòng)詞后面的賓語從句要使用虛擬語氣用法。即從句中的動(dòng)詞使用should+動(dòng)詞原形，或者將should省略。.我們建議Tom去休息一下。他堅(jiān)決要求我到場(chǎng)。國王命令囚犯明天要實(shí)施死刑。他們要求我們派他們?nèi)ツ莾汗ぷ?。WesuggestedthatTom(should)havearest.HeinsistedthatI(should)bepresent.Thekingorderedthattheprisoners(should)bekilledthenextday.Theyrequestedthatwe(should)sendthemtoworkthere..2、以上動(dòng)詞相應(yīng)的名詞構(gòu)成的名詞性從句（包括主語從句，表語從句和同位語從句）也要使用虛擬語氣。從句中的動(dòng)詞形式一樣。

order,advice,suggestion,proposal,demand,request,desireIt’ssuggestedthattheplanbecarriedout.Mydemandisthatsheshouldcometoseemeonceaweek.Allofusarefortheadvicethatthechemicalfactoryshouldbecloseddown..4、幾種特殊結(jié)構(gòu)中虛擬語氣的用法；1）wish

+賓語從句現(xiàn)在：過去：未來：過去時(shí)(did/were)過去完成時(shí)(haddone)would/could/might+V.shouldIwishIwereabird.(現(xiàn)在)IwishIhadn’tmadesuchamistake.(過去)Wewishourparentswouldn’tpunishus.(未來).2）wouldratherthat-現(xiàn)在：過去：未來：Iwouldratheryoupaidmenow.(現(xiàn)在)Iwouldratheryouhadgone,too.(過去)Don’tcome.Iwouldratheryoucametomorrow.(未來)過去時(shí)過去時(shí)過去完成時(shí).3）asif/though+從句現(xiàn)在：過去：過去時(shí)過去完成時(shí)Helooksasifheweredrunk.Theytalkedasiftheyhadbeenfriendsforyears.Shelovesthebabyasifitwereherownson.Itseemsasifitwerespring.Irememberthewholethingasifithadhappenedyesterday..4.It’shightime+that-should+V.過去時(shí)你該走了。我們?cè)撍X了。It’shightimethatyouwent.It’shightimethatyouweregoing.It’shightimethatyoushouldgo.It’stimethatwewenttobed.It’stimethatweshouldgoto

bed..5）without和butfor構(gòu)成虛擬。(butfor要不是)

Withoutsunlight,people’slifewouldbedifferentfromtoday.

Butforyourhelp,Iwouldn’thavefinishedthework.Butforwater,itwouldbeimpossibletoliveinthedesert..6）Ifonly…(要是…就好了)

IfonlyIknewhisname!Ifonlywehadfollowedyouradvice!IfonlyIcouldseehimagain!要是我們的父母能和我們住在一起就好了。要是我沒錯(cuò)過火車就好了！Ifonlyourparentscouldlivewithus!IfonlyIhadn’tmissedthetrain!.
