读甲、乙两地区1月等温线分布图，回答下题。

阅读下面材料，完成下列各题。

       2016年11月30日，联合国教科文组织保护非物质文化遗产政府间委员会通过决议，将中国申报的“二十四节气”列入人类非物质文化遗产代表作名录。

       材料一：【二十四节气】立春、雨水、惊蛰、春分、清明、谷雨、立夏、小满、芒种、夏至、小暑、大暑、立秋、处暑、白露、秋分、寒露、霜降、立冬、小雪、大雪、冬至、小寒、大寒。

       材料二：农耕时代，当时没有现代技术，一切靠天吃饭，农田的耕作播种需要了解天象，预测天气气候。于是，我们的先人就发现可以通过观察日月星辰的变化来认识外界自然变化，认识一年中时令、气候、物候等方面变化规律，慢慢总结出了“二十四节气”。

       材料三：从科学角度上讲，“二十四节气”是根据地球绕太阳公转的轨道也就是太阳在黄道上的位置来划分的。视太阳从春分点，也就是黄金零度出发，此刻太阳垂直照射赤道，每前进15度为一个节气；运行一周又回到春分点。为一回归年，24个节气正好360度。

       材料四：不仅古代，在现代“二十四节气”也已融入我们生活的方方面面：清明节气的祭祖活动、冬至的吃饺子等；在农村，二十四节气仍然指导着农民朋友们的农事活动；中医的理论体系会要求医生考虑节气，也就是结合天气气候特点和病人的病症来看病，广大老百姓也会按照节气规律来改变作息饮食和养生。
