　　虚拟条件句：条件状语从句是非真实情况时，要用虚拟语气。
　　If条件句 主句
　　与现在事实相反 did(be动词用were) would(或could, should, might) do
　　与过去事实相反 had done would(或could, should, might) have done
　　与将来事实相反或可能相反 did(were) should do
　　were to do
　　would(或could, should, might) do
　　1.和现在时相反
　　1）If I were you, I would study hard.
　　2）If it rained, I would not be here now.
　　2.和过去时相反
　　1）If the doctor had e last night, the boy would have saved.
　　2）If I had not studied hard, I would have failed in the exam last term.
　　3.和将来事实相反
　　1) If it should rain tomorrow, we would stay at home.
　　2) If I were to go to the moon one day, I could see it with my own eyes.
　　3) If you missed the film tonight, you would feel sorry.
　　★注意问题：
　　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。
　　eg: If you had worked hard, you would be very tired now.
　　3、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：
