问题
选择题
—I’m sorry. There was too much traffic on the road.
—Don’t be late again. The meeting for 15 minutes.
A．has begun
B．has stopped
C．has been on
D．has finished
答案
答案：C
题目分析：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
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
