问题补充：

Mr. Green to Beijing two weeks ago. He there many times.

A. has gone; has been

B. went; has been

C. has gone; went

D. went; went

答案：

A. has gone; has been

(答案→)B. went; has been

C. has gone; went

D. went; went

解析：have gone to意为“到某地去”，说话时该人不在现场，一般不用第一人称、第二人称代词作句子的主语。have been to意为“曾经去过某地”，现在已不在那里了，后可接次数，如once，twice，three times等，表示“去过某地几次”，也可和 just，never，ever等连用。
