17．The villagers _______ the buried people without stop since the accident happened．（　　）
A．searched forB．have searched for
C．had searched forD．have been searching for

分析 村民们在事故发生以后一直在一刻不停地寻找被埋的群众．

解答 答案：D．
根据后面的时间状语without stop since the accident happened，可知应该用现在完成时，而且搜寻的结果是未定的，所以搜寻还在进行，所以用现在完成进行时，表示从过去某一时刻开始一直持续到现在，而且这一动作还将进行下去，表达的是一种强烈的情感，即不放弃搜寻被困群众．所以选D．

点评 分清不同时态的具体用法很关键．
