Question

 Even if you had not been able to see her, you ______ us.

A．told

B．had told

C．should tell

D．should have told

Answer

D

【解析】

试题分析：考查虚拟语气的用法。由had not been able 可以看出条件状语从句是对过去的虚拟，主句没有自己的时间状语从语义上看也是对过去的虚拟，所以谓语动词应该是should  have done句意：即使你见不着她，你也应该告诉我们一声。故选D； should也可用ought to，“should have done”表示本应该做某事却没做。

考点：考查虚拟语气及语境的理解。
