(二)语言文字运用Ⅱ（本题共2小题，11分） 阅读下面的文字，完成21一22题。 材料一： 失温是一种生理现象。当人体的产热速率低于散热速率，体 内热量不足以保持体温，大脑、心、肺等核心器官温度降低时，人体 就会失温。失温的典型症状有剧烈寒战、语言不清、肌肉不受控制 等。如果失温严重，人会失去意识，甚至死亡。 户外徒步者要谨防失温的发生。徒步者往往考虑到保暖的问 题，却忽视大量出汗带来的失温风险。徒步者要选择干得快的内 衣，不要选择不容易导汗的棉质内衣。如果预计徒步时间较长，徒 步者要备好干粮和饮料，以便随时补充能量。如果在冬季徒步，或 前往高寒地区徒步，徒步者要备齐帽子、手套、围脖、防风衣、厚袜 子、防风面罩等物品，并适时穿戴或脱下。
