虚拟语气:虚拟语气用来表达不可能或难以实现的愿望,与事实相反的假设,通常分为基本的三种形式。 

 

 

  1. 与现在事实相反的虚拟:

  If + did / were + ……, …… would

  should

  could + do (动词原形)

  might

  If I were you, I would go abroad at once. (I am not you.)

  If he knew it now, he could help me. (He doesn't know it now.)

  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 littleearlier 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.
