问题 Which of the following is the result, if a sunbather stays on the beach for a long time?
Which of the following is not a possible damage by UV radiation?
选项 A、Sunburn.
B、The loss of skin elasticity.
C、Thickness of epidermis.
D、The deterioration of dermis.
答案C
解析 题意：下列哪项不是紫外线辐射对人体造成的伤害?表皮层变厚。短文第三段提到了紫外线辐射对人体产生的危害，其中有“皮肤变黑，失去弹性，过早形成皱纹，表皮变薄，变干”，从这里看出危害之一并不是表皮变厚而是变薄，故选C。
