问题补充：
---Where is Jim?
---He to Yunnan and he be back until next year.
A. has, been; won’t
B. has gone; will
C. has gone; won’t
D. has been; will
答案：
A. has, been; won’t
B. has gone; will
(答案→)C. has gone; won’t
D. has been; will
解析：句意：吉姆在哪里？他去了云南，直到下周他才回来。have been to曾经去过某地，强调经历，如果是地点副词to 要省略。have been in在某地，表状态，have gone to去了某地，表示不在这里。根据后文可知去了云南还没回来，又因为not until,直到……才……，故选C。
