高二英語虛擬語氣公開課課件1.英語動詞有三種語氣，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，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Q:What’sthedifferencebetweenthetwosentences?IfIamfree,Iwillvisityou.IfIwereabird,Iwouldflyintothesky.→（虛擬條件句）→(真實條件句）Whatwouldyoudoifyouwonthelottery?IfIwonthelottery,Iwould…IfIwonthelottery,Iwouldbuyanexpensivecar.(與現(xiàn)在事實相反）IfIwonthelottery,Iwouldbuyavilla.（與現(xiàn)在事實相反）Ifhehadgotupearly,hewouldnothavebeenlateforschool.（與過去事實相反）Ifhe__________morecarefully,he_________________thecaraccidentyesterday.（與過去事實相反）haddrivenwouldnothavehadIfI________howtoswim,I__________________trappedinthisisland.（與過去事實相反）hadlearntwouldnothavebeen假如他來了,我們對他說什么呢？Ifheweretocome,whatshouldwesaytohim.假如他看見我,就會認(rèn)識我。Ifheshouldseeme,hewouldknowme.1、一般條件句中的虛擬語氣時間If條件句主句過去haddonewouldshould+havedonesthcouldmight現(xiàn)在助動詞be用were實義動詞do用did

三個建議：advise,suggest,propose四個要求：demand,require,request,ask

這些動詞后面的賓語從句要使用虛擬語氣用法。即從句中的動詞使用should+動詞原形，或者將should省略。1.我們建議Tom去休息一下。2.他堅決要求我到場。3.國王命令囚犯明天要實施死刑。4.他們要求我們派他們?nèi)ツ莾汗ぷ鳌?.WesuggestedthatTom2.HeinsistedthatIpresent.4.Theyrequestedthatwe3.Thekingorderedthattheprisonersshouldhavearest.(should)beShouldbekilledthenextday.shouldsendthemtoworkthere.3、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(did/were)過去完成時(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)過去時過去時過去完成時5）without和butfor構(gòu)成虛擬。(butfor要不是)

Withoutsunlight,people’slifewouldbedifferentfromtoday.

Butforyourhelp,Iwouldn’thavefinishedthework.Butforwater,itwouldbeimpossibletoliveinthedesert.三、虛擬語氣注意點：1.假設(shè)條件從句謂語動詞發(fā)生的時間與主句所假設(shè)的謂語動詞不一致，叫做錯綜條件虛擬語氣。主句和從句的謂語動詞要依照假設(shè)的時間而定。Iftheweatherhadbeenfiner,thecropswouldbegrowingstillbetter.Ifyouhadfollowedtheteacher’sadvice,youwouldn’tbeinthehospital.三、虛擬語氣注意點：

2.當(dāng)insist表示“堅持認(rèn)為”，suggest表示“表明、暗示”時，后面的賓語從句不用虛擬語氣。Heinsistedthathehadnotenteredthehouse,and(heinsisted)thatheshouldbesetfree.Hispalefacesuggestedthathewasweak.1.Thevolleyballmatchwillbeputoffifit_____.
