混合型虚拟条件句 中从句叙述过去,主句叙说现在或将来 那么和条件状语从句中的虚拟 表示和过去事实相反 怎么区分?

应该是错综虚拟条件句,所谓错综虚拟条件句即条件从句与主句所指不,如从句指,而主句即指的是现在或将来,此时应的语境情况,上面提到的三种类型对时态作的：
If it had rained last night, the ground would be wet now. 要是昨晚下过雨的话,现在地面就会是湿的.
You would be much better now if you had taken my advice. 假若你当时听我的话,你现在就会好多了.

二、一点说明
条件从句用 if I were…时,既可指现在也可指：
If I were you, I would stay. 我要是你我就会留下.
If I were you, I’d go to night school. 我要是你,我会上夜校.
If I were not busy, I would have come. 假若我不忙,我早就来了.
也可用 if I had been you也表示：
If I had been you,I’d have taken the job. 我要是你,我就那份工作了.
而且,条件状语从句有一定的规律,错综虚拟条件句,只可根据实际情况
