D. is to end; will meet
答案：
(答案→)A. will have ended; will be meeting
B. will end; will meet
C. will be ended; am going to meet
D. is to end; will meet
解析：考查动词时态。句意：- 明天晚上9点钟我会去看你的演出。--抱歉，到那时候我的演出已经结束了，那时会正在会议室里接见记者呢。从上下文可知then 指的是9:00 tomorrow evening.，那么时间状语by then就是将来完成时的标志，所以演出结束应该用将来完成时，后句是指明天晚上9点钟的时候正在接见记者，所以正确选项是A 。
