—Did you go to the fashion show last week?
—I , but I was fully occupied the whole week.
A. must go
B. must have gone
C. would go
D. would have gone

A. must go B. must have goneC. would go(答案→)D. would have gone解析：考查虚拟语气：句意：--上个星期你去看时尚展览了吗？--我本来想去的，但是整个一星期我都在茫茫碌碌。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，虚拟语气的条件句被省略了：if I hadn’t been fully occupied the whole week.主句用would have done。选D。

这个解释是对的
