问题补充：

. He wasted a lot of time playing football, otherwise he the exam.

A. had passed

B. passed

C. would pass

D. would have passed

答案：

A. had passed

B. passed

C. would pass

(答案→)D. would have passed

解析：考查虚拟语气。根据otherwise“否则”可知，本题是含蓄条件句，相当于if虚拟条件句。根据wasted可知，是过去的事情，对过去的虚拟，用过去完成时，主句用would have done。故选D。
