We didn’t know his telephone number, otherwise we (__) him.
A.would have telephoned
B. must have telephoned
C. would telephone
D. had telephoned
参考答案与解析
答案:A
解析:考查虚拟语气。句意:我们不知道他的电话号码,否则我们就给他打电话了。otherwise“否则”相当于if引导的虚拟条件句,在这里表示对过去情况的虚拟,we (__) him相当于if引导的虚拟条件句的主句,对过去情况的虚拟,主句用would/could+have done,故选A。
