  虚拟语气的特殊用法

  1.含蓄条件句

  (1)有时假设的情况并不以条件从句形式表示出来,而是通过一个介词短语或其他方式表示。常用的词或短语有:without, but for, but that, otherwise, or, if only等。

  Without your help (=If we had not had your help), we could not have succeeded.

  要是没有你的帮助,我们是不会成功的。

  (2)在某些暗含虚拟条件的简单句中,虚拟语气可通过上下文表现出来。谓语动词用should/would do形式或should/would have done虚拟形式。

  Any man in his position would have done like that.

  任何人处在他的位置都会那么做的。

  You should (ought to) have come earlier.

  你本应来得早点。

2.错综时间条件句
