At no time the rules of the game. It was unfair to punish them.
A. they actually broke
B. would they actually break
C. did they actually break
D. they had actually broken

A. they actually brokeB. would they actually break(答案→)C. did they actually breakD. they had actually broken解析：本题考查动词时态和部分倒装用法。当否定词或具有否定含义的短语置于句首时，句子要用部分倒装。at no time意为“绝不，在任何时候都不”，置于句首用部分倒装，故排除A，D。再根据已知时态was，可知讲的是过去的情况。句意：事实上他们绝对没有违反游戏规则。惩罚他们是不公平的。句意：事实上他们绝对没有违反游戏规则。惩罚他们是不公平的。故C正确。
