Question

A. Had it not been   B. Were it not

C. Was it not       D. Hadn’t it been

Answer

A

【解析】

试题分析：考查if条件句的虚拟语气及其省略。句意：要不是她在上学路上被车撞受伤的事实，她可能已经通过考试。根据if条件句的虚拟语气，主句中might have passed可知是与过去事实相反的虚拟。本题主句用might have passed那么从句就用had done结构 ；虚拟条件句中省略连词“if ”，而把助动词had提到主语前。A符合if条件句的虚拟语气中主句的用法。故选A 。

【名师点睛】

If 条件句的虚拟语气有三种情况：

1.与现在事实相反： 从句用过去时（be动词用were的形式），主句用would/could/should/might+动词原形

2.与过去事实相反：从句用过去完成时，主句用would/could/should/might+ have done

3.与将来事实相反: 从句用过去时（be动词用were的形式）/should do/were to do，主句用would/could/should/might+动词原形

虚拟条件句中常省略连词“if ”，而把系动词，助动词，情态动词提到主语前。做这类题，要根据已经给出的主句或从句的谓语动词来推出是与过去，现在还是将来事实相反，然后再得出答案。
