—I’msorry.Therewastoomuchtrafficontheroad.—Don’tbelateagain.Themeetin

—I’m sorry. There was too much traffic on the road.—Don’t be late again. The meeting for 15 minutes.A.has begunB.has stoppedC.has been onD.has finished

C解析试题分析：句意：对不起，路上交通太拥堵了。不要再迟到了。会议已经开始15分钟了。for 15 minutes.表示一段时间，谓语动词要有延续性，begin改为be on，故选C考点：延续性动词和非延续性动词点评：非延续性动词向延续性动词的转变熟记一下几个：leave --- be away, borrow --- keep, buy --- have, begin/start --- be on, die --- be dead, leave --- be away from, fall asleep --- be asleep

就是这个解释
