虛擬語氣主要有與現(xiàn)在事實相反、與過去事實相反、與將來事實相反的虛擬,以及幾種特殊情況,should、wish等虛擬語氣。

  1. 與現(xiàn)在事實相反的虛擬:

  If + did / were + ..., ... would/ should/ could/ might + do (動詞原形)

  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. 與過去事實相反的虛擬:

  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. 與將來事實相反的虛擬:

  (1) If + should + v., ... would + v. (可能性很小)(譯作“萬一”)

  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.
