题目内容
12.-I'm sorry.There was too much traffic on the road.-Don't be late again.The meeting for 15minutes.( )
A. | has begun | B. | has stopped | C. | has been on | D. | has finished |
分析 --很抱歉,路上车辆太多了.
--别再迟到了.会议已经开始15分钟了.
解答 答案:C
根据句意"会议已经开始15分钟了"句中的时间状语for 15 minutes 表示动作延续的时间段,所以用现在完成时,且句子中的谓语动词必须是延续性动词,现在完成时的构成是:主语+have/has+动词的过去分词;四个选项中,只有选项C中的be on(开始,上映)表状态,可延续性,可以与时间段连用,表示"…开始多长时间了"其他三个选项中的动词begin,stop,和finsih都是非延续性动词,不能与时间段连用.故答案为C.
点评 本题考查了动词的时态.做题时,一定要特别关注有关的时间短语,这是判断句子时态的标志.在没有时间状语的情况下可以联系上下文根据语境来做出正确判断.
