Question

【题目】But for those interruptions, the meeting _____ half an hour ago．

A．was finished B．would have finished

C．would finish D．had been finished

Answer 1

【答案】B

【解析】句意：要不是那些干扰，这个会议半小时前就结束了。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。故选B。
