问题补充：
---Where is our English teacher? ---She London.
A. went to
B. has went to
C. has gone to
D. has been to
答案：
A. went to
B. has went to
(答案→)C. has gone to
D. has been to
解析：此题重点考查have been to和have gone to的区别。have been to：曾经去过
have gone to ：去了（表示现在在那个地方）have been to可以用任何人称 have gone to不能用在第一、第二人称 have been to为去过，表示回来了 have gone to为去了，表示还没回来 去过，回来了”用been，“去了，没回来”用gone,两者均可后接地点，前者表示去过某地，通常可与表示次数的状语连用；后者表示到某地去了，强调说话的当时去某地的人不在场
根据题干的含义可知此题选择C.
