问题补充：

You can hardly imagine what great difficulty we had the task.

A. finishing

Bfinished

C. to finish

D. finish

答案：

(答案→)A. finishing

B. finished

C. to finish

D. finish

解析：考查固定词组have difficulty (in) doing sth意思“做某事有困难”，句子You can hardly imagine…是个宾语从句，句子difficulty we had finishing the task是个定语从句，先行词是difficulty，从句we had finishing the task，所以选A
