托福语法之条件完成时

  这种时态由would/should+完成式构成:

  肯定式: I would/should have worked

  you would have worked等

  否定式: I would not/should not have worked等

  疑问式: would/should I have worked?等

  否定疑问式: should I not have/shouldn’t I have worked?

  would you not have/wouldn’t you have worked?

  这种形式用于:

  (a)条件句中。

  (b)would和should的特殊用法中。

  (c)过去时中,相当于将来完成时:

  I hope he will have finished before we get back.

  我希望在我们回来之前他已经做完。

  I hoped he would have finished before we got back.

  我曾经希望在我们回来之前他已经做完。
