4、条件是否能够实现,能够实现是真实条件句,不能使用虚拟语气;假设的条件不能实现则是非真实条件句,要用虚拟语气.判断这个假设是与哪个事实相反。通常有三种情况:①与过去事实相反。②与现在事实相反。③与将来事实可能相反I:虚拟条件句:1.虚拟现在时表示与现在事实相反的假设,其if从句的谓语形式用动词的过去式(be一般用were),主句用would/should/could/might+动词原形。Ifplaceswerealike,therewouldbelittleneedforgeographers.如果各个地方都一样,就不需要地理学家了。2.虚拟过去时是表示与过去事实相反的假设,if从句的谓语
5、形式用过去完成时即had+过去分词,主句用would/should/could/might+have+过去分词。Ifhehadknownyouraddressyesterday,hewouldhavetelephonedyou.3.虚拟将来时是表示对将来实现的可能性很小的或不确定的假设。If从句的谓语形式用一般过去式或用wereto/should+动词原形,主句用would/should/could/might+动词原形。Ifheweretoleavetoday,hewouldgettherebyFriday4.省略if采用倒装语序的条件句。有时可以把含有助动词、情态动词、be或have的
6、虚拟条件句中的连词if省去,而将had,should,were等词提到主语之前,即用倒装结构。Hadheworkedharder,hewouldhavegotthroughtheexams.Werehetoleavetoday,hewouldgettherebyFriday.WereIinyourplace,Iwouldn’tdothat.5混合虚拟语气有时主句和从句的谓语动词指不同的时间,这时需要用混合虚拟语气。一般来说,在这种情况下,主从句谓语动词指代的时间不同,所以我们又可以错综时间条件句,在这种虚拟情况,动词形式应根据实际情况灵活使用,在做这些题目时候尤其要注意每道题目的提示语:时
7、间状语。绝大多数情况下,从句或者主句都有相关的时间状语,这是我解题的关键。Ifyou_____thatlatemovielastnight,youwouldn’tbesosleepy.A.haven’twatchedB.didn’twatchC.hadn’twatchedD.wouldn’thavewatched答案选C。HadPaulreceivedsixmorevotesinthelastelection,hewou
