考博英语语法重点总结（8）

　　Many dead would now be alive if they have not attempted to return for something.

　　Had Paul received six more votes in the last election, he would be our chairman now.

　　混合虚拟语气还有一种情况就是事实和虚拟假设的混合句，这样的句子不仅仅是时间的不同，而重要是事实和假设的混合。

　　I would have gone to visit him in the hospital had it been at all possible, but I was fully occupied the whole of last week.

　　该句前半部分是假设虚拟，而后半部分是事实的陈述。

　　Your math instructor would have been happy to give you a make-up examination had you gone and explained that your parents were ill at the time.

　　该句前半句用的是假设虚拟，后半句主句也用的是假设虚拟(如果你去并且解释的话)，但是后半句的从句用的是事实语气，因为“父母病了”是客观事实，故不需要用虚拟形式had been。
