虚拟语态指不可能发生的事,你当作假设来讲.现在多称为第三条件句.
比如:
1)非虚拟语态(真实条件句):
If it rains tomorrow,I won't go there.
(如果明天下雨,我就不去了.--可能下雨)
2)虚拟语态(费真实条件句)
If it rained today,it would be cooler.
(如果今天下雨,就会凉快些.--此时此刻并没有下雨)
其他:
If I were you,I would do it this way.(我不可能是你)
If I were the president of the U.S.,I would do...(你不可能是美国总统)
