问题补充：
--- When will you return to your hometown? ---.
A. Not until the end of this month
B. Until next week
C. A few days ago
D. A few weeks before
答案：
(答案→)A. Not until the end of this month
B. Until next week
C. A few days ago
D. A few weeks before
解析：句意：你何时回故乡？本月底。A few days ago 几天前，用于一般过去时态；A few weeks before几周以前，用于过去完成时；Not until the end of this month和Until next week都可用于一般将来时，但使用Until next week时谓语动词必须是延续性动词，而本句谓语动词return是一个结束性动词，所以选A。
