Question

--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

Answer 1

D

试题分析：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
