Question

I would have gone to visit him in the hospital had it been at all possible, but I_______ fully occupied the whole of last week.

A．were

B．had been

C．have been

D．was

Answer 1

D

考查时态。I would have gone to visit him in the hospital had it been at all possible是含有虚拟语气的句子；but I_______ fully occupied the whole of last week.是真实的情况，要用陈述语气，再根据时间状语last week，可知要用一般过去式。所以选D。
