Question

       for the free tickets,I would not have gone to the film so often.

A．If it is not                              B．Were it not

C．Had it not been                         D．If they were not

Answer

C

【解析】

试题分析：考查省略if的虚拟条件句。从主句中would not have gone可以看出是与过去相反，故从句应该使用had done.故选择C。C答案省略了if，相当于if it had not been.句意：要不是免费的票，我不会这么经常去看电影。

考点：考查省略if的虚拟条件句。
