I was not hearing to the teacher or else I his questions.A. answered B. had answered C.

问题补充：

I was not hearing to the teacher, or else I his questions.

A. answered B. had answered C. would have answered C. have answered

答案：

解析：考查含蓄虚拟语气。or else相当于if引导的条件状语从句，根据was not可知指的是过去的事情，所以主句I his questions要用助动词加现在完成时态。所以选C。
