一、混合虚拟语气 d=D-s
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。 dH y 9

A. haven’t watched B. didn’t watch 3`bQ0-D;

Had Paul received six more votes in the last election, he would be our chairman now. lq-KM8j
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。 YO$Ig:a#
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. %e~xO x
该句前半部分是假设虚拟，而后半部分是事实的陈述。 `D4Wg<,9
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. x3q^}sj%
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。 Gy

二、含蓄虚拟条件句 ^H x}.?1
含蓄条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常来表示含蓄虚拟条件的手段有： $

9B)0

(11)动词原形表示虚拟 @KM?agtlbl
