题目内容
19．---Sorry．I am late．---It doesn't matter．The meeting ______ for just several minutes（ ）| A． | has begun | B． | has started | C． | has been on | D． | had been on |
分析 --抱歉，我来晚了．
--没关系．会议刚开始了几分钟．
解答 答案：C．
根据for just several minutes可知，这是一个表示一段时间的时间状语，for引导的时间短语通常用于现在完成时，现在完成时态的结构为have/has+动词的过去分词，而begin是瞬间性动词，不能持续一段时间，不能和for引导的一段时间连用，所以要用be on，主语是The meeting，所以助动词用has，故选C．
点评 本题主要考查现在完成时，用法：表示过去发生或完成的动作对现在造成的影响或结果，还表示过去发生动作一直持续到现在．其结构是have/has+及物动词的过去分词．此题注意短暂性动词和延续性动词区别．
