问题单项选择题

正常皮肤有皮脂和汗液，它们保持着皮肤的柔软和滋润。手掌和脚跟等处无皮脂只有汗液维持着皮质的柔润，冬天出汗时，皮肤干燥，再加上这些部位与外界接触、摩擦，皮肤变得厚硬又缺乏弹性，当活动张力过大时，就会引起皲裂。如果裂缝深过头时，就有可能裂入真皮而造成裂口见血或鲜血直流，非常疼痛。下列选项中能正确反映这段话的观点是( )。

A．正常皮肤由皮脂和汗液组成

B．冬天皮肤容易因为干燥而引起皲裂

C．皮肤的结构与功用

D．皮肤在夏天比冬天更易保持柔润

答案

参考答案：B

解析：选项A可以直接从文中找到，但它不是本文主要表述的观点；文中并没有提及皮肤的结构与功用，所以可以排除C；选项D在文中并没有提到，所以也可以排除。由文中“冬天出汗时，皮肤干燥，再加上这些部位与外界接触、摩擦，皮肤变得厚硬又缺乏弹性，当活动张力过大时，就会引起皲裂’’可以得知B正确地反映了本文的观点。
