问题补充：
－I’ll come to see your performance at 9:00 tomorrow morning.
－I’m sorry, by then my performance and I reporters in the meeting room.
A. will end; will meet
B. will have ended; will be meeting
C. will be ended; am going to meet
D. is to end; will be meeting
答案：
A. will end; will meet
(答案→)B. will have ended; will be meeting
C. will be ended; am going to meet
D. is to end; will be meeting
解析：句意：--我将明天上午9:00来看你的演出。--对不起，到那时，我的演出早就结束了，我在那时正在会议室接受记者的采访。根据句意到那时演出早就结束了，这是将来某个时间之前已经完成的应该用将来完成时will have done；在将来某个时间正在做事，应该用将来进行式will be doing，故选B。
