it not been for the free ticket I would not have gone to the cinema.A. WereB. ShouldC. If

问题补充：

it not been for the free ticket, I would not have gone to the cinema.

A. Were

B. Should

C. If

D. Had

答案：

A. Were

B. Should

C. If

(答案→)D. Had

解析：考查虚拟语气：if的非真实条件句可以省略if，将should，were，had提前到主语前面，从主句I would not have gone to the cinema.可知是和过去相反的动作，填had，相当于if it had not been for the free ticket，句意是：如果不是因为免费的票，我就不会来电影院了。选D。
