1、虚拟语气虚拟语气表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或与事实相反的假设等。一般常用于正式的书面语中：一、虚拟语气在条件句中的用法1．表示与现在事实相反，谓语动词的主要形式如下：条件从句主句动词过去式（be的过去式一般用were）would(should,could,might)＋动词原形1)IfIwereyou,Ishouldn’tdothat.2)Wewouldgowithyouifwehadtime.3)Wecouldaskhimifhewerehere.4)IfIkn
2、ewhistelephonenumber,Iwouldringhimup.2．表示与过去事实相反，谓语动词的主要形式如下：条件从句主句had＋过去分词would(should,could,might)＋have＋过去分词1)Ifhehadseenyouyesterday,hewouldhaveaskedyouaboutit.2)Ifyouhadcomeearlier,youwould(might)havemethim.3)Ishould(would)havecalledyouifIhadknowny
3、ourtelephonenumber.3．表示与将来事实可能相反，谓语动词的主要形式如下：条件从句主句动词过去式或should＋动词原形或wereto＋动词原形would(should,could,might)＋动词原形1)Ifitshouldrain,thecropswouldbesaved.2)Ifitweretosnowtomorrow,theywouldnotgoout.※在实际运用中，主句中的谓语和条件从句中的谓语动词所发生的时间往往不一致，这时应作相应的调整：1)Ifhehadfollo
4、wedthedoctor’sadvice,hewouldbeallrightnow.2)Ifitshouldbefinetomorrow,weshouldhaveboughttheticketyesterday.※有时条件从句可用介词短语或分词短语所替代，如：1）WithoutourParty,wecouldnotliveahappylife.2）Theboywouldhavediedbutforthedoctor.3）Givenmoretime,Icouldhavefinishedtheworkr
5、emarkably.※虚拟条件句往往可以省略if,采取将had,should,were提到句首的倒装句式表达。如：1)Ifhewerehere,hewouldhelpyou.>>>Werehehere,hewouldhelpyou.2)Ifyouhadaskedhimforit,hewouldhavegivenittoyou.>>>Hadyouaskedhimforit,hewouldhavegivenittoyou.3)Ifyoushouldgotheretomorrow,youcouldhave
6、agoodtime.>>>Shouldyougotheretomorrow,youcouldhaveagoodtime.二、一些“should＋动词原形”虚拟语气的用法1．在动词suggest,order,demand,propose(建议),prefer,request,urge(力劝、竭力主张),desire(愿望),insist,decide,require,advise,command(命令、指挥),arrange等后面的宾语从句中，一般用“should＋动词原形”（should往往可以省略
7、）。如：1)Isuggestthatwe(should)holdameetingtonight.2)Heorderedthatall(should)takepartinthework.3)Theyinsistedthatwe(should)begintheworkatonce.※当insist作“坚持（认为）、坚持（应该）”解时才用虚拟语气，而作“力言、强调”解时不用虚拟语气；当suggest作“建议”解时才用虚拟语气，而作“暗示、表明”解时不用虚拟语气。这两个动词比较特殊。试比较：Mikeinsi
8、stedthatwe(should)gowithhim.Mikeinsistedthathehadneverstolenthebike.Hesuggestedthatwe(should)haveanothertry.Hissmilingfacesuggestedthathewassatisfiedwithmyanswer.2．在名词suggestion,order,proposal,plan,desire,request,decision,idea,advice等之后
