—Sorry, he Hong Kong for a meeting and he back in a week.

A. went; was

B. has been to; will be

C. has gone to; has been

D. has gone to; will be

答案：

A. went; was

B. has been to; will be

C. has gone to; has been

(答案→)D. has gone to; will be

解析：句意：你好，我能跟布莱克先生通电话吗？对不起，他去香港开会了，在一周后回来。第一空用现在完成时，对现在造成了影响，has been to去过，现在已经回来了；has gone to去了，人在去某地途中或已经到达某地，不在说话的地方。第二空根据时间状语in a week一周后，是表将来的时间，故用一般将来时，结合语境故选D。
