2、虚拟条件句有单一条件句，也有混合虚拟条件句，所以不能只根据从句与某一事实相反来判断主句就与该事实相反，同样，也不能想当然地认为主句与某一事实相反，从句也就与该事实相反。如(2)：
(2)If you ______that movie last night， you wouldn't be so sleepy.(1993.6)
A.hadn't watched
B.haven't watched
C.wouldn't have watched
D.didn't watch
答案：A
从句与过去事实相反，而主句与现在事实相反。
再如：
If he weren't such a kind man，he wouldn't have lent a hand to such people as you the other day.(从句与现在事实相反，主句与过去事实相反。)
Were my friends not to come tomorrow，I wouldn't have bought so many foods.(从句与将来事实相反，主句与过去事实相反。)
3、if引导条件状语从句时，可以将were/had/should提至句首，省略if考试时经常是将省略if的与含有if的选项并列，在这种情况下，应注意分清从句的时态，尽管多数情况下都是倒装的结构为正确选项。如(3)、(4)、(6)和(7)。
再如：
Were they here now，they could help us.=If they were here now，they could help us.
Had you come earlier，you would have met him.=If you had come earlier，you would have met him.
