题目解答
答案
D. the thin, protective, outer layer of skin
解析
本题考查对英文单词“epidermis”含义的理解以及对皮肤各层结构特点的掌握。解题思路是明确“epidermis”的准确释义,然后将各选项内容与该释义进行对比,找出正确选项。
- “epidermis”的意思是“表皮”,它是皮肤最外层的一层薄薄的、具有保护作用的组织。
- 选项A:“the layer of skin that contains sweat glands”,含有汗腺的皮肤层是真皮层,并非表皮,所以A选项错误。
- 选项B:“the layer of skin that contains blood vessels and nerve endings”,含有血管和神经末梢的皮肤层也是真皮层,不是表皮,所以B选项错误。
- 选项C:“the deep layer of skin that is responsible for fat storage”,负责脂肪储存的皮肤深层是皮下组织,不是表皮,所以C选项错误。
- 选项D:“the thin, protective, outer layer of skin”,薄薄的、起保护作用的皮肤外层,这与“epidermis”(表皮)的定义相符,所以D选项正确。
