4、hewouldcomeheretomorrow!e.Iwouldratherthathewouldcomeheretomorrow.[学一学]虚拟语气表示说话人所说的话不是事实，而是一种假设、愿望、怀疑或推测。虚拟语气主要用于条件从句、让步从句和名词性从句中。通过观察、分析以上几组例句，我们可以发现与之相对应的虚拟语气用法原则：一、虚拟语气在条件从句中的用法：1.与现在事实相反或实现可能性不大：If+从句(谓语用did/were)，主句(谓语用would/should/could/might+do)。注意：be的过去式通常用
5、were。①IfIwereyou,Iwouldstudyhard. ②Ifitrained,Iwouldnotbeherenow. 2.与过去事实相反：If+从句(谓语用haddone)，主句(谓语用would/should/could/might+havedone)。①Ifthedoctorhadcomelastnight,theboywouldhavesaved. ②IfIhadnotstudiedhard,Iwouldhavefailedintheexamlastterm
6、. 3.与将来事实相反：If+从句(①did/were②weretodo③shoulddo),主句(谓语用would/should/could/might+do)。①Ifitshouldraintomorrow,wewouldstayathome. ②IfIweretogotothemoononeday,Icouldseeitwithmyowneyes. ③Ifyoumissedthefilmtonight,youwouldfeelsorry. [请关注]1、If条件句中绝对不
7、可出现“would”。2、根据句中的时间状语,有时可能出现“错综时间虚拟”的情况,即主句可能是现在的情况,条件句也许是发生在过去的情况,但主从句都要对应遵守上述句型。①IfIwereyou（现在）,Iwouldhavetaken(过去)hisadvice.②IfIhadtakenmyraincoatwithmethismorning(过去),Iwouldnotbe(现在)wetnow.3、当从句谓语中有were/had/should时，可将if省略，而将were/had/should提前。即：省if倒装虚拟
