一、虚拟语气表示一种不能实现的假设。该语法主要用于if条件状语从句。也可用于主语从句、
表语从句、宾语从句等。
二、if条件状语从句中虚拟语气的判断
判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。通过句子
意思,看假设的条件是否能够实现,能够实现是真实条件句,不能使用虚拟语气;假设的条件
不能实现则是非真实条件句,要用虚拟语气。
判断这个假设是与哪个事实相反。通常有三种情况:①与过去事实相反。②与现在事实相
反。③与将来事实可能相反。
三、“后退一步法”
后退一步法是指在准确地判断了该句与哪一事实相反后,按虚拟语气的后退一步法处理从
句谓语动词的时态。即:在非真实条件状语从句中,谓语动词按正常情况“后退一步”。也就
①与过去事实相反,在从句中用过去完成时形式表示。
②与现在事实相反,在从句中用过去一般时形式表示。
③与将来事实可能相反,在从句中用过去将来时形式表示。
主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。

If I were a teacher, I would be strict with my students.
If it should snow tomorrow, they couldn't go out.
四、注意事项
①if条件句中如有were, should, had,可以省去if,并使用倒装语序。
②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。
->宾语从句中的虚拟语气
一、wish 后面宾语从句中的虚拟语气
wish 后面宾语从句中的虚拟语气,按“后退一步法”处理从句的谓语动词。注意:与哪
个事实相反,不能以主句的'时态为判断依据,而是根据从句的意义判断。
二、表示“要求、建议、命令”等动词后面的宾语从句中的虚拟语气
从句中用“should + 动词原形”构成。而且should可以省去。用于此结构的动词有:
advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose,request, suggest等。
注意:当insist表示“坚持认为”、suggest表示“表明,显示”时,不用虚拟语气。
The look on his face suggested that he was quite satisfied with what I had done
for him. He insisted that he was honest.
三、would rather +从句
在这种结构中,从句的位于动词用过去形式表示虚拟。
I would rather you did this instead of me.

一、It be + 形容词 + that ...(should)...
用于该句型的形容词是:necessary, good, inportant, right, wrong, better, natural,proper, funny, strange, surprising .

参考答案与简析:
1. C。一些表心理活动的动词(如think, suppose,guess, hope等)可用“过去完成时或一般过去时后接宾语从句”表示一个“与事实不符的.过去的想法、猜想或希望”。
2. D。可用“should / would + have liked / loved + to do sth.”表示“过去本来想要做某事而未曾做到”。
3. A。可用“was / were + to have done sth.”表示“过去本来计划、安排做某事,但并未做到”。
4. C。可用“would rather + have done sth.”表示“主观上本来宁愿做某事,而实际上却没有做”,用否定式则表示“主观上本来宁愿不做某事,而实际上却做了”。
5. B。be supposed有“应该”之意,后面只接不定式,若不定式用完成式,表示“过去本来应该做某事,而实际上没有去做”,用否定式意思相反,此用法也含有批评、责备、抱怨之意。
6. D。当if条件状语从句表示对过去情况的假设时,从句谓语用had done,主句用would have done。
7. D。有时虚拟if条件从句不出现,而是通过某些词语(如otherwise, or, without, but for, but等)暗示虚拟语境,这时句子要用虚拟语气,注意要准确判断时间,决定句子谓语动词形式。此题显然与过去相关。
