“北半球,1月份大陆上等温线向南(低纬)凸出,海洋上则向北(高纬)凸出;7月份正好相反。”高中《地理》上册的这段文字,以北半球为例勾勒出等温线凸向的规律。许多同学在学习这部分知识时,由于不能把等温线的凸向与其形成的原因——海陆热力性质差异联系起来思考,不甚理解,只能囫囵吞枣,死记强背课本上的结论,考试中常常犯张冠李戴的错误。 “In the northern hemisphere, the upper isotherm of the continent protrudes southwards (low latitudes) in January, and the northward (high latitudes) ocean protrudes; the opposite is true in July.”The text of the book “Geography” in the high school, in the northern hemisphere As an example, the rules of isotherm convexity are outlined. When many students learn this part of the knowledge, they cannot think of the convexity of the isotherm and the reason of its formation—the difference in the nature of the sea and the land’s thermodynamics. They don’t understand it, they can only swallow it, and they strongly remember the conclusion on the textbook. Guilty of making mistakes.
