一、混合虚拟语气 0*}%v:uN9
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。 Q,z^eMk'd:
If you that late movie last night, you wouldn’t be so sleepy. COk ;z.Kn
A. haven’t watched B. didn’t watch ([a[ fi
C. hadn’t watched D. wouldn’t have watched 答案选C。 n; fUwon
Many dead would now be alive if they have not attempted to return for something. (r+#}z}
Had Paul received six more votes in the last election, he would be our chairman now. *Af:^>mh
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。 K}p!W"!o
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. cy-Bhk0H
该句前半部分是假设虚拟，而后半部分是事实的陈述。 wa*/Am9;~
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. "=97:H {!
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。 PA(XdT{
二、含蓄虚拟条件句 8V$ :th('
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： U ,w J 8
（1）介词或介词短语，如but for, but that, without, in case of, under more favorable condition等。 39(]UO6^;

If only I had more money, I could buy a car. V{j>09u
(注：lest, for fear that 和 in case 引起的从句中谓语动词多用should+动词原形，但可以不用虚拟语气，而用动词的陈述语气形式。)例如： D~i m1h;>
The foreign teacher spoke slowly in case we misunderstood him. 这位外籍教师说得很慢以免我们听不懂。 5D32d1A
