-did you find tie missing man in the flood?-no,but we______many times to get in touch him ever since.a.tired b.had tired c.are trying d.have tired为什么呢?b不可以吗?
正确答案应该是D have tried.
翻译：--你在洪水中找到了那个失踪的人吗?--没有,但是自那以后我们尝试了很多次以和他取得联系.
1.try...该动作是发生在过去的动作didn't find...in the flood之后的,所以不不可能用B had tried,因为过去完成时强调的是“过去的过去”,即发生在另一个过去的动作/时刻之前的动作.
2.ever since意思是“自...以来/后”,表示该动作/状态从过去的某个动作/时刻开始,延续到现在.
其做时间状语时,句子一般都是用现在完成时或现在完成进行时.
所以正确答案是D.
C不对,除非改成have been trying才行.

C表示还在继续找，还没有结果，将来有可能继续。
B表示现在这个动作已经停止了
