问题
选择题
But for those interruptions, the meeting _____ half an hour ago.
A．was finished
B．would have finished
C．would finish
D．had been finished
答案
答案：B
题目分析：句意：要不是有这些打断，这个会议在半小时前就会结束了。But for“要不是”，But for those interruptions,="if" it had not been for those interruptions,是和过去相反的虚拟语气，所以主句用would have done，选B。
