wouldshould+dosthcouldmighthaddonedid/wereshoulddoweretodowouldshould+dosthcouldmightwouldshould+havedonesthcouldmight留意点1:省略if的条件句有时侯在运用时可省略if,句子则可换成下列形式，即“were/had/should+主语”。如1.IfIwereaboy,Iwouldjointhearmy.2.Ifhehadtakenmyadvice,hewouldhavesucceeded.

3.Ifitwerenotfortheexpense,IwouldgotoBritain.

WereIaboy,Iwouldjointhearmy.Hadhetakenmyadvice,hewouldhavesucceeded.Wereitnotfortheexpense,IwouldgotoBritain.注:

Ifitwerenot/hadnotbeenfor…也是常见的虚拟句型,意思是“要不是……”例如:Ifithadnotbeenfor

yourhelp,wewouldnothaveachieved

somuchinourwork.Ifitwerenotforthewisedecision,

wecouldnotbelivingahappylife.留意点2:时间错综条件句当条件状语从句表示的行为和主句表示的行为所发生的时间不一样时，动词的形式要依据它所表示的时间作相应调整。Ifyouhadfollowedmyadviceyesterday,youwouldbebetternow.Hemightbepraisednow,ifhehadmaderapidprogress.留意点3:with,without,butfor,but,or,otherwise等形式的含蓄条件句。在虚拟语气中，有的句子可能没有明显的由“if”引导的条件从句，但是句子中隐含着一个条件，这种句子称为含蓄条件句Withoutair(Iftherewerenoair)，therewouldbenolivingthings.假如没有空气的话，就不会有生物了。But_foryourhelp(Ifithadn'tbeenforyour
