问题补充：
My sister Tony for ten years next year.
A. has been married to
B. has married to
C. will be married to
D. will marry to
答案：
A. has been married to
B. has married to
(答案→)C. will be married to
D. will marry to
解析：考查时态。根据next year可知，应该使用一般将来时，排除A、B；marry是短暂性动词，不能与一段时间连用，排除D，be married to sb for+时间，意为“和某人结婚多久了”，故选C。
