A.had been B.were C.was D.would be
考的是虚拟语气啦，很急躁的额，大家帮忙下喽！

Answer 1

Had it been possible I would have told him the answer,but I ____ so busy then.
A had been B were C was D would be
答: C
分析: Had it been possible = If it had been possible
这叫通过倒装省略虚拟语气条件句中的if
but引出一个过去的事实情况.I was very busy then. 我当时太忙了.
其实前面这个条件句不要也行：
I would have told him the answer,but I was so busy then.
这叫隐含虚拟条件.
=If I hadn't been so busy then, I would have told him the answer.

a 过去的话虚拟要用过去完成时
