题目

这个英语句子在哪里断句?
I would have gone to visit him in the hospital had it been at all possible,but I was fully occupied the whole of last week.
请问这个句子怎么断句?请说明断句的理由,

答案

hospital后面其实可以加一个逗号I would 到hospital是一个虚拟语气,后面had it实际句子全的话,应该是if it had...,但虚拟语气中if什么什么,往往可以把if去掉,然后把句子倒装一下,也就成了现在的had it断句的话就是I....
