In order to find the missing child, the villagers___________ all they can in the past five hours.
A.have been doingB.didC.doD.had done
A

试题分析:考查时态。根据关键词in the past five hours说明应该使用现在完成时或者现在完成进行时。句意:为了找到失踪的孩子,在过去的五个小时里,村民们一直都在做他们能做的所有事情。根据句意是指一直在做,故使用现在完成进行时。故A正确。
点评:对于时态的考查要根据句子的关键的时间状语和句子的意思来辨析。本题的关键词就是in the past five hours该短语常与现在完成时或者现在完成进行时连用。
