选择题
－Linda, the phone in your office can’t be connected all the time. Why?
－Oh, sorry, Miss Miles. The service ___ since last Wednesday.
A．has been stopped
B．is stopped
C．was stopped
D．had been stopped
答案
答案：A
题目分析：句意：--Linda，你办公室的电话一直接不通，怎么了？-哦，对不起，Miles小姐，自从上个星期三服务就停了。时间状语是since last Wednesday.和现在完成时连用，而且the service和stop是被动关系，用现在完成时的被动语态，选A。
