虚拟语气的几个问题

题目

虚拟语气的几个问题
1.If I 【were 】not busy,I would have come.假若我不忙,我早就来了.
为什么后面用would have done 前面不用had done
2.Should you be fired,your health care and other benefits 【will not 】be immediately cut off.如果你被解雇了,你的医疗保险和其他受益不会立即解除.
虚拟语气后面的主句应该是wouldn't啊,为什么是will not?

答案

1.主句和通常状况相反,我忙指的是 一直都很忙,过去,现在,将来都忙
当然这里用If I had not been busy 更好.
2.If sb.should do,或should sb.do这个并非一定是虚拟语气,should翻译成万一.所以后面用will not是可以的.
