1、Grammar&usageSubjunctiveMood虚拟语气Revision虚拟语气1）概念 虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。2）在条件句中的应用 条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。在条件状语从句和结果状语从句中,表示与事实相反的条件和结果。1)与现在事实相反：If主语…,主语+V原wereV-edshould(wouldcould,might)2)与过去事实相反：If主语,主语+haveVed3)与将来
2、事实相反：If主语…,主语+V原should(wouldcould,might)shouldweretoshould(wouldcould,might)hadVed虚拟语气假设条件句型注意点：1.假设条件从句谓语动词发生的时间与主句所假设的谓语动词不一致，叫做错综条件虚拟语气。主句和从句的谓语动词要依照假设的时间而顶。Iftheweatherhadbeenfiner,thecropswouldbegrowingstillbetter.Ifyouhadfollowedtheteacher’sadvice,youwouldn’tbeinthehospital.
3、2.假设条件虚拟倒装。条件从句中有should，were，had三个助动词可以把if省略，并将这三个词提至句首。IfIwereyou,Iwouldgiveitup.WereIyou,Iwouldgiveitup.Ifitwerenotforyouradvice,wecouldn’thavegotoverthedifficulties.Wereitnotforyouradvice,wecouldn’thavegotoverthedifficulties.IfIhadhadtime,Iwouldhaverunroundthatlakeagain.HadIhad
4、time,Iwouldhaverunroundthatlakeagain.Ifthereshouldbeaflood,whatshouldwedo?Shouldtherebeaflood,whatshouldwedo?注意： 在虚拟语气的从句中，动词'be'的过去时态一律用"were"，不用was，即在从句中be用were代替。IfIwereyou,Iwouldgotolookforhim.如果我是你，就会去找他。Ifhewerehere,everythingwouldbeallright.如果他在这儿，一切都会好的。典型例题_____todothewo
5、rk,Ishoulddoitsomeotherday. A.IfwereIB.IwereC.WereID.WasI在虚拟条件状语中如果有were,should,had这三个词主语提前,变成were,should,had+主语的形式。但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说WereInottodo.,而不能说Weren'tItodo.1.Hadyoulistenedtothedoctor,you_________allrightnow.A.areB.wereC.wouldbeD.wouldhavebeen2._
