Question

【题目】—Did you find the missing couple in the mountain yesterday?

—No, but we to get in touch with them ever since.

A. have tried B. have been trying

C. had tried D. had been trying

Answer 1

【答案】B

【解析】

句意：——你昨天在山里找到那对失踪的夫妇了吗?——没有，但从那以后我们就一直在和他们联系。考查动词时态辨析题。ever since从那时到现在，用于现在完成时；but表转折，根据句意语境，可知现在仍在设法与他们取得联系，需用现在完成进行时，故选B。
