2. 与过去事实相反的虚拟:If had done ..., ... would (might) have done ...If I had known your telephone number yesterday, I would have phoned you. (I didn't know your telephone number.)If you had come here a little earlier just now, you might have met her. (You didn't come here earlier.)
3. 与将来事实相反的虚拟:(1) If should v., ... would v. (可能性很小)(译作“万一”)If it should rain tomorrow, you could stay at home.If I should fail, what should Ido?
(2) If did / were to v ..., would v. (完全不可能)If the sun were to rise in the west, I would lend you the money.If you finished it in 3 minutes, I would give you my car.
