考博英语语法：混合虚拟语气

考博英语语法：混合虚拟语气 46yq F  
　　有时主句和从句的谓语动词指不同的时间，这时需要用混合虚拟语气。一般来说，在这种情况下，主从句谓语动词指代的时间不同，所以我们又可以错综时间条件句，在这种虚拟情况，动词形式应根据实际情况灵活使用，在做这些题目时候尤其要注意每道题目的提示语：时间状语。绝大多数情况下，从句或者主句都有相关的时间状语，这是我解题的关键。 tny^sG/'

　　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. #"T< mM7  
　　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。 ORc20NFy7
