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：试题分析：考查动名词做主语。这里的施动者是阳光,被动者是皮肤,显然皮肤暴露在阳光下要使用被动形式,被动形式就要加be动词而做主语要将动词名词化,故be变为being,所以选c.expose是暴露的意思。句意：皮肤在阳光下暴露太久会受伤的。
