for the fact that she got hit by a car and broke her leg on her way to school, she might have passed the exam.

A. Hadn’t it been

B. Had it not been

C. Was it not

D. Were it not

答案：

A. Hadn’t it been

(答案→)B. Had it not been

C. Was it not

D. Were it not

解析：考查虚拟语气的省略倒装，if的非真实条件句可以省略if，提前had，should ，were，句意是：如果不是因为事实是在回家的路上，她被汽车撞到了腿断了，她就通过考试了。选B=if it had not been the …表示和过去相反的虚拟语气。
