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。
