高中英语虚拟语气的十大句型虚拟条件句：条件状语从句是非真实情况，在这种情况下要用虚拟语气。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,would,或might)＋动词原形(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＋过去分词(3) Ifthedoctorhadcomelastnight,theboywouldhavebeensaved.(4) IfIhadnotstudiedhard,Iwouldhavefailedintheexamlastterm.3．条件从句与将来事实不一致，其句型为：句型 3：If+主语+过去时/should+动词原形/wereto+动词原形，主语+should(could,would,或 might)+动词原形(5) Ifitshouldraintomorrow,wewouldstayathome.(6) IfIweretogotothemoononeday,Icouldseeitwithmyowneyes.(7) Ifyoumissedthefilmtonight,youwouldfeelsorry.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，但都要遵守上述句型。如：(8) Ifyouhadstudiedhardbefore,youwouldbeacollegestudentnowandyouwouldgraduatefromacollegeinfouryear'stime.3・条件句中如果出现 were,had,should 可省去 if,将主语与这些词倒装。例如：(9) Hadthedoctorcomelastnight,theboywouldhavebeensaved.(10) WereItogotothemoononeday,Iwouldseeitwithmyowneyes.(11) Shoulditraintomorrow,wewouldstayathome.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，基本句型：句型 4 主语+(should)+动词原形(12) MotherinsistedthatJohn(should)gotobedat90clock.(宾语从句)(13) Itwasrequiredthatthecrops(should)beharvestedatone(主语从句)(14) Itissurprisingthatsheshouldn'tpassthemathexam.(主语从句)(15) Thesuggestionthathe(should)beinvitedwasrejected.(同位语)(16) 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。三、虚拟语气在一些特殊词中的使用或含蓄条件句：句型 5：wish后的宾语从句与现在愿望不一致：主语＋过去时；与过去愿望不一致：主语＋had＋过去分词/could＋have＋过去分词；与未来愿望不一致：主语＋would/co...
