I would have gone to visit him in the hospital had it been a

題目：

I would have gone to visit him in the hospital had it been at all possible,
but I was fullyoccupiedthe whole of last week.
請問爲什麼用was呢?
「had it been at all possible」是什麼意思?

解答：

翻譯：我本來想到醫院看你,但是整個上周我都在茫茫碌碌,如果真正可能的話（可以去看你）.
這是虛擬語氣的句子,表示對過去的虛擬,說明這件事情已經過去,表示遺憾呢
had it been at all possible 省略 if it had been possible at all.
at all 是加強語氣的短語
but I was fully occupied the whole of last week.be occupied表示忙碌的狀態,
occupied是形容詞,忙碌的相當於busy；last week 這是過去的時間,所以用過去時
歡迎追問,
