高考英语语法专题讲解-虚拟语气1 虚拟条件句：1.1 与现在事实不一致，其句型为：If +主语did，主语should（could, would, 或might）do.如：If I were you, I would study hard. （可倒装）If it rained, I would not be here now.1.2 与过去事实不一致，句型为： If +主语haddone，主语should（could, would, 或might）havedone.如：If the doctor had come last night, the boy would have been saved. （可倒装）比较这一句：If the doctor had come last night, the boy would be saved. -（混合虚拟:要求根据语境判断！）1.3 将来事实不一致，句型为：do，主语should（could ，would, 或might）do. 如：If it should rain tomorrow, we would stay at home.（可倒装）If I were to go to the moon one day, I could see it with my own eyes.（可倒装）If you missed the film tonight, you would feel sorry.（混合虚拟）P.S:1、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。1.4 虚拟倒装：在条件句中如果出现were, had, should可省去if，将主语与这些词倒装，例如：Had the doctor come last night, the boy would have saved.Were I to go to the moon one day, I would see it with my own eyes.Should it rain tomorrow, we would stay at home.1.5 without, but, but for（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。1.5.1 与现在事实相反：Without you, I would never know him. But for your cooperation, we wouldnt have done the work so well. I would be most glad to help you, but I am busy now.I am busy now, otherwise I would do you the favor! 1.5.2 与过去事实相反：But that she was afraid, she would have said no.
