1、英语虚拟语气专项训练一.虚拟条件句：条件状语从句是非真实借况，在这种借况下要用虚拟语气。1、条件从句与现在事实不一致，其句型为：句型1:if+主语+过去时,主语+should(could,wou1d,或might)+动词原形，如:(1)ifiwereyou,iwouldstudyhard.(2)ifitrained,iwouldnotbeherenow.2、条件从句与过去事实不一致，其句型为：句型2：if+主语+had+过去分词，主语+should(could,would,或might)+have十过去分词，如：(3)ifthedoctorhadcomelastnight,theboywoul
2、dhavesaved・(4)ifihadnotstudiedhard,iwouldhavefailedintheexamlastterm・3、条件从句与将來事实不一致，其句型为：句型3：if+主语十过去时/should十动词原形/wereto+动词原形，主语+should(could,would,或might)+动词原形,如:(5)ifitshouldraintomorrow,wewouldstayathome・(6)ifiweretogotothemoononeday,icouldseeitwithmyowneyes・(7)ifyoumissedthefilmtonight,youwould
3、feelsorry.注意问题：1、if条件句中绝对不可以出现“would”。2、根据句中的时间状语,有时可能出现"混合虚拟”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，但都要遵守上述何熨,如：(8)ifiwereyou,iwouldnothavemissedthefilmlastnight・(现在过去)(9)iftheyhadstartedintheearlymorning,theywou1darriveinhalfanhour(过去将來)(10)ifyouhadaskedhimwhenyousawhimlasttime,youwouldknowwhattodonow・(过去
4、现在)(11)ifyouhadstudiedhardbefore,youwouldbeacollegestudentnowandyouwouldgraduatefromacollegeinfouryears'time・3、在条件句中如果出现were,had,shouldnJ'省去辻,将主语与这些词倒装,例如：(12)hadthedoctorcomelastnight,theboywouldhavesaved・(13)wereitogotothemoononeday,iwouldseeitwithmyowneyes・(14)shoulditraintomorrow,wewouldstayatho
5、me・二、名词性虚拟语气：在表示命令、建议、要求、惊叹时的名词性从句中需用虚拟语气，基木何熨：句型4：主语+(should)+动词原形，①当宾语从句从的谓语是suggest,request,insist,desire,demand，propose,order,command,arrange等动词时，如：(15)motherinsistedthatjohn(should)gotobedat9o'clock.(宾语从句)(16)itwasrequiredthatthecrops(should)beharvestedatonce.(主语从句)②advice,idea,order,plan,deman
6、d,proposal,suggestion,request等名词之后的表语从句和同位语从句中.如：(17)thesuggestionthathe(should)beinvitedwasrejected.(同位语从句)(18)theirdemandisthattheirwages(should)beincreased.(表语从句)注意：在这种句子中绝不可以出现"would""must""could"等。注意：当suggest表示暗示，表明时,不用虚拟语气，用陈述语气•如：(1)thesmileonherfacesuggestedthatshewassatisfiedwithourwork・当in
7、sist表示坚持认为Z意时，不用虚拟语气，用陈述语气.如：(2)themaninsistedthathehadneverstolenthemoney①itisordered/desired/decided/requested/insisted等后的主语从句中(3)itisdesiredthatweshouldgeteverythingreadytonight・②itisnatural/necess
