4-9，回答（1）年均温最高的为 _洲，年均温最低的为 _洲。（3）自己学校所在地的年均温大约是_。5、想一想，世界年平均气温的分布有什么规律？6、读图 10、11，北京与悉尼相比，1 月气温高的城市是；7月气温高的城市是。7、读图 11，北半球同纬度的大陆和海洋，7 月的气温高。你能简单地说明其原因吗？【预习诊断】北半球陆地气温最低月一般为_月，最热月一般为 _月。【预习质疑】1.预习本节后存在的问题:2.预习本节后新的想法：第 1 课时第 1 页（二）课 堂 实 施课堂实施基本流程为：预习交流精讲点拨拓展延伸系统总结集体设计个人修订【预习交流】教师反馈学生预习情况。小组内互相交流。【精讲点拨】指导学生阅读教材 P.74 图 4-9“世界年平均气温分布”，1教师说明等温线的含义：2指导学生掌握简要分析等温线图的方法3在教师的引导下，学生分小组合作探究，总结世界年平均气温的分布规律：由低纬度向高纬度气温逐渐降低；同纬度范围内，海洋与陆地气温不相同；同纬度的陆地上，海拔高处气温较周围低。【拓展延伸】一般情况下，陆地上一天中的最高温值出现在14 时前后，最低温值出现在 日出前后。一年中，北半球中、高纬度大陆上，最高气温出现在7月，最低气温出现在1 月。南半球与此相反。据此可判断某地在南北半球中的那个半球一年内，月平均气温的最高值与最低值的差，称为气温年较差。【系统总结】一、气温二、世界年平均气温的分布1等温线 2世界年平均气温的分布规律指 导 学生读图，创设条件，采用发现法教学，由学 生 发 现 问题，提 出 问题，展 开 讨论、质疑、探究。第 1 课时第 2
