虛擬語氣

1）概念

虛擬語氣用來表示說話人的主觀愿望或假想，所說的是一個條件，不一定是事實，或與事實相反。2）在條件句中的應用

條件句可分為兩類，一類為真實條件句，一類為非真實條件句。非真實條件句表示的是假設的或實際可能性不大的情況，故采用虛擬語氣。時間謂語動詞的虛擬形式if從句主句現在動詞過去式（be多用were）would/should/could/might+動詞原形過去had+過去分詞would/should/could/might+have+過去分詞將來動詞過去式或should/wereto+動詞原形would/should/could/might+動詞原形Ⅰif條件句的虛擬語氣

1.與現在事實相反時,其表現形式為:if主語+v-ed,主語+would(might,could,should)+v.Eg:Ifweleftnow,weshouldarriveingoodtime.IfIwereyou,Iwouldrefusethemoney.與過去事實相反時,其表現形式為:if主語+hadv-ed,主語+would(或might,could,should)+havev-ed.Eg:Ifwehadhadtime,Wewouldhavedroppedby.IfIhadn’tbeentold,Iwouldn’thaveknownwhatthesewerefor.與將來事實相反時,其表現形式為:

if主語+should(或wereto)v.,主語+Would(或might,could,should)+v.Eg:Ifyoudropped

theglass,itwouldbreak.Ifyouleaved

thereforawhile,you'dchangeyourmindaboutthatplace.

虛擬語氣假設條件句型注意點：1.錯綜時間句的虛擬語氣當條件從句與結果主句所表的時間不一致時,虛擬語氣的形式應當做相應的調整.如:Ifyouhadfollowedtheteacher’sadvice,youwouldn’tbeinthehospitalnow.Ifyouhadcomeandattendedthemeetingyesterday,youwouldknowwhatwearedoingnow.2.假設條件虛擬倒裝。條件從句中有should，were，had三個助動詞可以把if省略，并將這三個詞提至句首。IfIwereyou,Iwouldgiveitup.WereIyou,Iwouldgiveitup.Ifitwerenotforyouradvice,wecouldn’thavegotoverthedifficulties.Wereitnotforyouradvice,wecouldn’thavegotoverthedifficulties.IfIhadhadtime,Iwouldhaverunroundthatlakeagain.HadIhadtime,Iwouldhaverunroundthatlakeagain.Ifthereshouldbeaflood,whatshouldwedo?Shouldtherebeaflood,whatshouldwedo?注意：

在虛擬語氣的從句中，動詞'be'的過去時態(tài)一律用"were"，不用was，即在從句中be用were代替。IfIwereyou,Iwouldgotolookforhim.如果我是你，就會去找他。Ifhewerehere,everythingwouldbeallright.如果他在這兒，一切都會好的。

典型例題

A.IfwereIB.Iwere

C.WereI

D.WasI

在虛擬條件狀語中如果有were,should,had這三個詞主語提前,變成were,should,had+主語的形式。但要注意，在虛擬條件狀語從句中，省略連詞的倒裝形式的句首不能用動詞的縮略形式。如我們可說WereInottodo.,而不能說Weren'tItodo.1.Hadyoulistenedtothedoctor,you_________allrightnow.A.areB.wereC.wouldbeD.wouldhavebeen2.__________anychangeaboutthedate,pleasetellmeimmediately.A.WilltherebeB.ShouldtherebeC.TherewillbeD.ThereshouldbePractise3.__________today,hewouldgettherebyFriday.A.WouldheleaveB.WasheleavingC.WerehetoleaveD.Ifheleave4.Shoulditrain,thecrops_____.A.wouldbesavedB.wouldhavebeensavedC.willbesavedD.hadbeensaved5.You_____comeearlier.Thebusleftamomentago.A.wouldB.shouldhaveC.mayD.have6.Whatshouldwedoifit_____tomorrow?A.shouldsnowB.wouldhavesnowedC.snowD.willsnow7.You_____suchaseriousmistakeifyouhadfollowedhisadvice.A.maynotmakeB.mightnotmakeC.shouldn’thavemadeD.mightnothavemade8.Ifitwerenotforthefactthatyou_____ill,Iwouldaskyoutodothisrightnow.A.wereB.hadbeenC.areD.shouldbe1.useotherwise,orandphrasesbeginningwithwith,withoutandbutfortoreplaceanif-clauseinimpliedconditionals

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。我們建議Tom去休息一下。他堅決要求我到場。國王命令囚犯明天要實施死刑。他們要求我們派他們去那兒工作。WesuggestedthatTom
