(2013·高考辽宁卷)At no time ________the rules of the game.It was unfair to punish them.
A．they actually broke
B．do they actually break
C．did they actually break
D．they had actually broken
答案
答案：C
选C。句意为“实际上他们从来没有违反比赛的规则。惩罚他们是不公平的”。at no time意为“决不；从不，任何时刻都不”，当其位于句首时，句子应该用部分倒装结构，故排除A项和D项；根据第二个句子的时态可知，此处应该用过去时态，故排除B项。
