B、traditional
C、common
D、rare
【正确答案】：C
【题目解析】：对于第（28）题，题目中描述的是老年人退休后迁移到南方某些地区已经成为一种普遍现象。根据语境，我们需要找到一个词来描述这种现象的普遍性。 A选项“strange”意为“奇怪的”，这与题目描述的情境不符，因为迁移并不是一件奇怪的事，而是一种趋势。 B选项“traditional”意为“传统的”，虽然老年人可能有一些传统的观念或习惯，但迁移本身并不是一种传统，而是随着时代变化而出现的。 C选项“common”意为“普遍的”，这符合题目描述的情境，老年人退休后迁移到南方地区已经成为一种普遍现象。 D选项“rare”意为“罕见的”，这与题目描述的情境完全相反。 因此，根据题目描述和语境，正确答案是C选项“common”，表示老年人退休后迁移到南方已经成为一种普遍现象。
