虛擬語氣(Subjunctivemood)①用來表示說話人所說的話不是一個事實,而是一種假設(shè),推測,懷疑;②是表示說話人的愿望,要求,命令,建議等。掌握基本定義后,我們再來看看常見的類型:一、虛擬語氣的常見形式(1)if條件從句+主句1.Ifitwerenotraining,weshouldgoforapicnic.2.Shewouldhavegonetothepartyifshehadbeeninvited.3.Ifitshouldfail,Iwouldtryagain.4.Ifyoushouldnotcometomorrow,wewouldputoffthemeetingtillnextweek.Attention: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.e.g:如果他在這兒,一切都會好起來。Ifhewerehere,everythingwouldbeallright.(2)常用虛擬語氣的句型(命令,要求,建議等)1.動詞+賓語從句一個堅持:insist;兩個命令:order,command;三個建議:suggest,propose,advise;四個要求:desire,demand,ask,requireIproposethatwe(should)setadeadlineforhandingintheplans.Isuggestthatwe(should)setoffatonce.Iinsistedthatwe(should)decidewhattodowithhim.Attention:虛擬語氣形式:(should)+動詞原形2.Itis(was)+上述動詞的過去分詞+that主語從句Itisdemandedthathe(should)leaveatonce.Itisrequestedthatshe(should)giveaperformanceattheparty.3.Order(suggestion,idea,proposal,advise)+be+表語從句Myadviceisthatwe(should)sendforadoctor.Oursuggestionisthatyou(should)befirsttogo.4.Itis(was)+important/necessary/strange/surprising/natural/possible/apity/nowonder+that主語從句Itisbestthathe(should)setoffatonce.Itisimportantthateverybody(should)betoldallthefacts.二、虛擬語氣的三種活用現(xiàn)象(一)、含蓄條件句含蓄條件句就是虛擬條件暗含在短語或上下文中,從句不表現(xiàn)出來。這時,必須根據(jù)句中表述的意義以及某些特定的信息詞來進行判斷。1.Withoutelectricity,humanlifewouldbequitedifferenttoday.A.isB.willbeC.wouldhavebeenD.wouldbeWithoutelectricity=Iftherewerenoelectricity(二)、時間錯綜句從句與主句或上下文所表述的時間不一致。在這種情況下,我們切不可照搬某種形式,而應(yīng)該按照句中所表述的時間關(guān)系,再選擇相應(yīng)的虛擬形式。例如:Iftheflowerhadbeenwatered,itwouldn’tdienow.A.wouldn’tdieB.isdeadC.hadbeendeadD.willnotdie(三)、虛實錯綜句虛實錯綜句是指虛擬現(xiàn)象與客觀事實錯綜交織在一起的句子,需要細心判斷哪一處是虛擬語氣,哪一處應(yīng)使用陳述語氣。Theymighthaveleftearlier,butthecarwasn’tready.A.canhaveleftB.mayhaveleftC.willhaveleftD.mighthaveleft...
