虚拟语气SubjunctiveMood嘉祥一中刘善西语法背景：英语语气的分类一、虚拟语气在条件状语从句的使用(1)虚拟条件句的结构(2)虚拟条件句的省略与倒装(3)特殊的虚拟条件句：错综式、含蓄式、Ifonly引导的感叹句二、虚拟语气在宾语从句中的用法(wish与wouldrather后的宾语从句)三、虚拟语气在asif/though从句的用法四、虚拟语气在It’stimethat中的用法陈述语气Iwenttothetheatreyesterday.祈使语气Let’sgo.虚拟语气IfIwereyou,Iwouldnotleaveheralone.二、条件状语从句表示主句的条件,分真实条件句和虚拟条件句两种。主从句构成时间（1）表示与现在事实相反的假设条件状语从句中的谓语动词用“过去式(be动词的过去式用were)”主句中的谓语动词“would/should/could/might+动词原形”。---Whatwouldyoudoifyouwonthelottery(彩票)?---IfIwonthelottery,Iwouldbuy…IfIwonthelottery,Iwouldbuyanexpensivecar.IfIhadalotofmoney,Iwouldbuyasuperbhouse(豪宅).IfIhadalotofmoneynow,Iwouldtravelaroundtheworld.Ifitwerefinenow,Iwouldgoshopping.a.Ifthey____(be)herenow,they__________(take)youradvice.b.Iftheworld-war_____(burst)outagain,what_____________(happen)toourpeopleonearthnow?c.Ifthepoliceman________(benot)inthatroomnow,it________(be)verydangerous.d.IfI____(be)inyourposition,I_________(ask)forteacher’shelp.(2).与过去的事实相反的假设Ifhe__________morecarefully,he_________________thecaraccidentyesterday.IfI________howtoswim,a.IfTom________(be)morecarefulintheexam,he________________(pass)italready.b.Ifyou_______(get)upearlier,you________________(catch)thefirsttrain.c.IfI_______(meet)youyesterday,we______________(go)totheconcerttogether.(3).与将来事实相反的假设Ifyousucceeded,everythingwouldbeallright.Ifyoushouldsucceed,everythingwouldbeallright.Ifyouweretosucceed,everythingwouldbeallright.Ifhegotupearlytomorrow,hewouldbeontime.假如他来了,我们对他说什么呢？a.Ifthere________(be)nonaturalresourceanymore,we___________(make)useofnuclearpower.b.What____________(happen)ifyou____________(getup)toolatetomorrow?c.IfRobots_____________(control)theworldsomeday,there________(be)nofriendship.Shoulditrain，thecropswouldbesaved.＝Wereittorain，thecropswouldbesaved.＝Ifitshould(wereto)rain，thecropswouldbesaved.如果下雨的话，庄稼就会得救了。主从句构成时间主句与从句的动作发生在不同的时间,这时主从句谓语动词的虚拟语气形式因时间不同而不同,这叫做错综时间条件句。Ifyouhadaskedhimyesterday,youwouldknowwhattodonow.（从句与过去事实相反,主句与现在事实相反。)Ifthestaffhadbeenmorecareful,themall(购物中心)wouldnotbeonfirenow.有时假设的情况并不以条件状语从句的形
