虚拟语气使用方法归纳英语的动词一般可带有三种不一样的语气陈说语气，祈使语气和虚拟语气不一样的语气用动词的不一样形式（有的还借助句法形式）来表达
一、虚拟条件句条件句有两类一类是真实条件句，一类是虚拟条件句假如假设的状况是有也许发生的，就是真实条件句，谓语用陈说语气If you dont workhard,you willfail.If itis finetomorrow,we willgo for a picnic.假如假设的状况过去、目前、未来都不存在，则为虚拟语气虚拟条件句和对应主句的动词形式列表条件从句的谓语动词形式主句谓语动词形式与过去事实相反的假设would/could/might/should havehad donedone与目前事实相反的假设过去时（wasf were）would/could/might/should do与未来事实相反的假设过去时（was-*were）;would/could/might/should doshould do;were to do.与目前事实相反的虚拟1What wouldyoudoif youwon thelotteryIf Iwere you,I wouldseize thechance to go abroad.If I had alot ofmoney now,I wouldtravel aroundthe world..与过去事实相反的虚拟2If youhad beenhere yesterday,you would have seenher.If hehad drivenmore carefully,he would not have had the car accidentyesterday.与未来事实相反的虚拟
3.If itwere torain/should rain/rained tomorrow,our planwould be put off.If wewere topicnic,we would not beable tohelp.
二、错综、混合虚拟语气一般，在上面表格里反应的是非真实条件句的虚拟语气模式，从句和主句的谓语动词时间是一致的，假如两者时间不一致，此时就是混合型虚拟语气混合型虚拟语气的使用规定“各自为政”，即从句和主句根据各自假设的时间不一样，采用上面表格中对应的的谓语动词形式.（从句是对过去的假设，主句是对目前的假
1.If I had seenyou,I wouldnot be so worriednow设）（从句是
2.If youhad notwatched televisionso latelast night,you wouldnot beso sleepynow.对过去的假设，主句是对目前的假设）（从句是对过去的假设,主
3.Had youfollowed the doctors suggestion,you would be finenow.句是对目前的假设）（从句是对过去的
4.If I had madesome moneylast summer,I wouldgo onholiday nextmonth.假设，主句是对未来的假设）（从句是对过
5.You didntlet medrive.If wehad drivenin turns,you wouldntbeso tired now.去的假设，主句是对目前的假设）.从句是对目前的假设，主句是对
6.If Iwere yourmother,I wouldlet yougo outthis weekend未来的假设
三、含蓄虚拟语气虚拟语气中的“含蓄之美”指的是含蓄虚拟语气由于有时假设的状况并不是以引导的if条件从句形式出现，而是通过某些短语等形式暗示虚拟语气的存在，常用的词语有with,without,假如…将怎样等等，这种句子往往有主句而无从but for,otherwise,or,even,in caseof,what if句考试时多数状况是对过去的假设过去But for your encouragement,I wouldnot havebeen admittedto thisuniversity.Without目前water,all liveswould die.过去He felttoo tiredyesterday,or hewould haveattended myparty.过去I washaving ameeting,otherwise I would havecome tosee youoff.
四、虚名词性从句的虚拟语气具有的使用方法，这一部分重要是有关提议和命令的有关从句，包括主语从句,宾语should+V从句，表语从句，同位语从句以及以之有关的形式主语宾语之类的从句记忆口诀一种坚持两个命令三个提议四个规定insist,order,command,suggest,advise,recommend,ask,require,demand,requesto宾语从句的虚拟语气
1.He insisted that themeeting beput off.The generalordered thatall the soldiers shouldleave.He givesorders that the soldiersshould leave.表语从句的虚拟语气
2.My suggestionis that we shouldstay hereforarest.同位语从句的虚拟语气
3.There isno suggestionthat she should resign.
4.主语从句的虚拟语气重要体目前It做形式主语的三种状况Ifs+p.p+that；Ifs+adj.+that；It s+n.+that常用的动词recommand,demand,desire,order,request,require,suggest,command常用的形容词important,necessary,right,advisable,natural,strange,surprising,regretful,urgent,vital,insistent,essential常用的名词duty,pity,no surpise,no wonder,shame,regret其实这些词在句子中其实也有提议命令类似的的意思It simportant that you shouldtake themedicine.It sa pitythatyoushould refusethe invitation.It sessential that we shouldlearn someknowledge aboutfist aid.It sdemanded thatall thestudents should go tothe playground.It wassuggested that heshouldjoin theclub activities.为形式宾语的状况实际上是上面形式主语的一种变形，是以为形式宾语的复合宾语
5.It it从句,背面的宾语补足语多为形容词或名词,常见词就是上面形式主语背面的那些词it Iconsiderit vitalthatheshould thinkdeeply beforeacting.We thinkit necessary that themeeting should beput off.某些词语如等有双重含义，因此在使用的时候要注意什么时候用虚拟语气，
6.suggest,insist什么时候不用虚拟语气Her smilesuggested that she was in favorof theplan.We insistedthat whatthe boydid waswrong.五.虚拟语气在特殊句式中的运用，重要有两种状况I.would rather,It stime...,for fearthat...在使用时要注意它的不一样使用方法由于自身可以直接接动would ratherwould rather词原形，构成（）或者would ratherdo sth.than do sth.else;would dosth.rather thandosth.else.而虚拟语气的是这样使用的（对目前或未来的假设）/would ratherwould rathersb.did had done（对过去的假设）I wouldrather hedidn,t gonow.They wouldrather theyhadn tattended theparty.（）（）（）…从句中常用过去式（有时也用）含提议It sabout high time that shoulddo,的意思汉语的意思为“是该做…的时候了”，也等于It stime forsb.todosth.（）It shigh time thatwewent home.（）It shigh timethatweshouldgohome.It shightimefor ustogohome.背面可以接虚拟语气也可以接其他语气，但仍然会有一种情态动词for fearthatshoulddo,I willnot makea noisefor fearthat Ishould/might disturdyou.这三种状况的虚拟语气有点相似II.wish+clause;as if/though+clause;If only后的宾语从句，谓语动词要用虚拟语气，其形式重要有三种（对目前的虚wish wish sb.did拟）；（对过去的虚拟）；（对未来的虚拟）.偶尔在对过去wish sb.haddonewish sb.would do的虚拟时，也会出现的状况wishsb.would have doneI wish I knewwhat wasgoing tohappen.She wishedshe hadstayed athome.I wishI would have seenher last night★此时要注意表达语气很强时用其使用方法同上假如要用仍How sb.Wish+clause,was然换成were.How IwishIwere abird.出现的虚拟语气重要有两种状况主句引导的状语从句；as if/though+as if/though seem/弓|导的表语从句look/smell+as if/though主句引导的状语从句主句主语（对目前的假设）；+as if/though+as if/though++did/were主句主语（对未来的假设）；主句主语+asithough++could/would do+as if/though++haddone（对过去的假设）等的从句状况基本上和上面一致seem/look/smellShe talksas ifshe kneweverything.He behavedas ifnothing hadhappened.注意不需要用虚拟语气的状况引起的感慨句规定用虚拟语气，表达愿望形式为用过去式或者If onlywould/could do,表达与目前或未来事实相反的愿望；用过去完毕式表达与过去事实相反的愿望If onlyhe werehere!If onlyyou wouldlisten toour advise!If onlyIhadnot beenbusy lastweek!★If only也可以用于虚拟条件从句中，如If onlyIhadmore money,I couldbuy acar!
