I would have gone to visit him in the hospital had it been at all possible,

题目

I would have gone to visit him in the hospital had it been at all possible,
but I was fullyoccupiedthe whole of last week.
请问为什么用was呢?
“had it been at all possible”是什么意思?

答案

翻译：我本来想到医院看你,但是整个上周我都在茫茫碌碌,如果真正可能的话（可以去看你）.
这是虚拟语气的句子,表示对过去的虚拟,说明这件事情已经过去,表示遗憾呢
had it been at all possible 省略 if it had been possible at all.
at all 是加强语气的短语
but I was fully occupied the whole of last week.be occupied表示忙碌的状态,
occupied是形容词,忙碌的相当于busy；last week 这是过去的时间,所以用过去时
欢迎追问,
