问题补充：
So sudden an attack that the enemy could hardly have any time to fly for their lives.
A. we made
B. we had made
C. did we made
D. had we made
答案：
A. we made
B. we had made
(答案→)C. did we made
D. had we made
解析：句意：我们进行了这么突然的袭击以至于敌人没有时间逃命。在so...that 结构中，so加修饰的部分位于句首时，主句的主谓一般采用部分倒装形式，将be动词/助动词/情态动词放在主语前面，因为是过去进行的袭击，所以用一般过去式，助动词did提到主语前面，本句的正常语序为we made so sudden an attack that the enemy could hardly have any time to fly for their lives.故选 C 项。
