高考英语语法专题讲解虚拟语气
1虚拟条件句：11与现在事实不一致，其句型为：
If主语＋did，主语＋should（couldwould或might）＋do
如：IfIwereyouIwouldstudyhard（可倒装）Ifitrai
edIwould
otbehere
ow
12与过去事实不一致，句型为：
If主语＋had＋do
e，主语＋should（couldwould或might）＋have＋do
e
如：Ifthedoctorhadcomelast
ighttheboywouldhavebee
saved（可倒装）比较这一句：Ifthedoctorhadcomelast
ighttheboywouldbesaved（混合虚拟要求根据语境判断！）
13将来事实不一致，句型为：
If主语＋should＋do，主语＋should（could，would或might）＋dowereto
如：Ifitshouldrai
tomorrowwewouldstayathome（可倒装）IfIweretogotothemoo
o
edayIcouldseeitwithmyow
eyes（可倒装）Ifyoumissedthefilmto
ightyouwouldfeelsorry（混合虚拟）PS1、If条件句中绝对不可出现“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，但都是遵守上述句型。
14虚拟倒装：在条件句中如果出现werehadshould可省去if，将主语与这些词倒装，例如：Hadthedoctorcomelast
ighttheboywouldhavesavedWereItogotothemoo
o
edayIwouldseeitwithmyow
eyes
fShoulditrai
tomorrowwewouldstayathome
15withoutbutbutfor（要不是）otherwise引起的短语或句子常暗含虚拟（语气较为含蓄）分3种情况动词作同上的变化。151与现在事实相反：WithoutyouIwould
