问题补充：
Her sister a rich man. They for twenty years.
A. married with; have married
B. married to; have married
C. married; have been married
D. has married with; have been married
答案：
A. married with; have married
B. married to; have married
(答案→)C. married; have been married
D. has married with; have been married
解析：marry是及物动词，跟某人结婚应该直接说marry sb．be married表示一种状态，且根据“for twenty years.”可知，表示说话时已经完成的动作，而且这个动作的结果对现在仍有影响，用现在完成时。
