问题补充：

to sunlight for too much time will do harm to one’s skin.

A. Being exposed

B. Exposed

C. Having exposed

D. After being exposed

答案：

(答案→)A. Being exposed

B. Exposed

C. Having exposed

D. After being exposed

解析：考查非谓语动词。句意：长时间日晒会对皮肤对不利。主语是being exposed to sunlight，谓语是will do harm to，宾语是skin，for too much time是定语。皮肤被晒伤，所以选择被动，所以是C或者D。但是D不能做主语，因为它前面是个介词，所以只能做状语。
