虚拟语气
【要点点拨】一：形式为(should)+v.1．宾语从句中。一个坚持（insist）,两个命令（order,command）,三条建议（advise,suggest,propose）,四项要求（demand,require,request,ask）.还有prefer，advise等词。注意：1）suggest和insist有例外Thesmileonhisfacesuggestedthathewassatisfiedwithourwork.（“暗示”“表明”）Themaninsistedthathehadneverstolenthemoney.2）这类动词的名词形式后的表语从句和同位语从句中也要用(should)+v.形式。另外，还有plan,idea等词。2．主语从句中1)Itisnecessary/important/strange/natural/essential/apity/ashame/nowonderthat….eg.Itisstrangethatheshouldhaveactedtowardshisparentslikethat.二：形式为在原本的时态上退一步，即“+过去”1.在条件句中的运用
条件从句主句与现在事实相反过去式（be一般用were）would/could/might+v.与过去事实相反had+过去分词would/could/might+have+过去分词与将来事实相反1）过去式2）should+v.3）wereto+v.would/could/might+v.（第一人称可用should,以上同）1)“混合虚拟条件句”或“错综时间条件句”主句和从句时间上不一致，从句可以和过去时间相反，主句可以与现在事实相反。Ifyouhadtakenmyadvicejustnow,youwouldbebetternow.2)if省略句。在条件句中，可省略if,把were,had,should提到句首，变为倒装句式。WereIyou,Iwouldseizethechancetogoabroad.3)含蓄条件句A)with,without,butfor等介词短语代替条件句Butfortherain,thecropswouldhavedied.(=Ifithadn’tbeenfortherain)B)其他手段Iwasillthatday.Otherwise,Iwouldhavetakenpartinthesportsmeeting.（副词）Hetelephonedtoinformmeofyourbirthday,orIwouldhaveknownnothingaboutit.（连词）Imighthavegivenyoumorehelp,butIwastoobusy.（连词）Givenmoretime,wecouldhavedoneitbetter.(分词短语)Itwouldbeamistakenottohelphim.（动词不定式）2.宾语从句中wish,wouldrather后,但wouldrather后所跟句子跟现在、将来相反用过去时，跟过去时间相反使用过去完成时。注意：不跟过去将来时。Iwouldratheryoucametomorrowinsteadoftoday.我宁愿你明天而不是今天来。3．asif(though)引导的从句中asif后的从句当表示真实情况时，用陈述语气。试比较：Itlooksasifitisgoingtorain./HetalksasifhehadbeentoAmerica,4．Itis(high)timethat…..过去时/should+v.5.用于ifonly引导的感叹句中“但愿，要是…就好了”
