问题补充：

—Most of the students went to the party yesterday. It is a pity you were absent.

—I wish I . But I was terribly busy.

A. did

B. had

C. were

D. would

答案：

A. did

(答案→)B. had

C. were

D. would

解析：考查虚拟语气的用法。Wish的虚拟语气用法为 对现在虚拟用did对过去虚拟用had done 对将来虚拟用would do ，根据I was terribly busy 可知，该句是对过去虚拟，故选择had done，省略形式为I wish I had.
