大学英语：虚拟语气表示假设的情况或主观的愿望

虚拟语气表示假设的情况或主观的愿望。我们已经学过虚拟语气在由if引导的虚拟条件句中的用法，如：

In case after case the difficulty could have been overcome—or might never have arisen—if the people involved had just treated one another with common courtesy.

I think that if I were allowed to add one small beatitude as a footnote to the other it might be:Blessed are the courteous.

虚拟语气还有许多其他的用法，本课再介绍以下几种。

17.It’s(high)time+带有虚拟式动词的从句

It’s time (that) you learned to be courteous.

It’s time (that) we got down to business.
