选择题
--Hello, Sandy. This is Jack. What are you doing?
---I’m watching a match. It started at 7:00 p.m. and _____ on for another an hour.
A．has been
B．was
C．had been
D．will be
答案
答案：D
题目分析：句意：你好，仙蒂，我是杰克，你在做什么？我正在看比赛。下午7点开始的，还需要一个小时。句中有for another an hour.表示一段时间，句中谓语动词要有延续性，be on表示上演，可以延续，故选D
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
