【题目】-Are you free tomorrow evening?

-Sorry, I’m afraid I ______a friend off then.

A. was seeing B. will have seen

C. will be seeing D. have seen

【答案】C

【解析】

试题分析：C；考查将来进行时。将来进行时由“will be+现在分词”构成，表示将来某一时间正在进行的动作或按计划或安排要发生的动作；根据上文：-Are you free tomorrow evening?可知问的是:明天晚上有没空，下文回答：那时我正在送朋友离开。体现的是某一时刻正在做的事情，所以用将来进行时。句意：——明晚你有空吗？——对不起，那时我恐怕正在送我的朋友离开。故选C
