教学内容：本课是小学英语教材北京版（一年级起）四年级上册Unit7 What is nature？Lesson23。整个单元的主题是谈论人与自然。本节课为单元第一课时，它的主题是自然界中的不同地区不同天气；第二课时的主题是亲近大自然；第三课时的主题是大自然的重要性；第四课时主题是人和自然和谐相处，第五课时主要是复习。本课对话部分呈现了两个场景：首先Lala和Maomao讨论雨、雪、冰、水的不同变化；其次是Mike在北京给身在悉尼的好朋友Eric打电话，谈论北京和悉尼的天气情况。课文中使用了日常交际用语“How’s the weather in Sydney？”以及回答“Bad. It’s raining hard.”。在Listen, Look, and Learn版块，主要是依托课文运用How’s the weather in… 并回答Bad. /Fine. /Cold. It’s…等练习询问天气的情况。关于天气的话题在三年级上册第五单元中学习过，所以在此基础上，本节课更深一步谈论了天气“怎么样”以及自然界中雨、雪、冰、水的不同变化。此外，本节课还加入了对温度和自然现象的学习与了解，渗透了自然科学等知识。学生情况： 1. 四年级的孩子有一定的英语语言基础，能够听懂、回答简单日常用语。学生在三年级上册中学习过四季的天气情况，有对天气的认知能力，知道表达天气的形容词rainy, sunny, snowy, windy, cloudy，hot, warm等。但是他们没有学习过温度表达法以及温度对雨、雪、冰、水的影响与变化。2. 小学四年级的学生好奇心强、活泼好动，善于模仿。同时，他们对于简单的事物有所掌握，同时对熟悉的知识有所感悟，具备表演的欲望。所以，本课采用多种活动形式增强学生参与的广度和深度，使他们在亲身体验中进行有效的学习，保持他们学习的欲望和兴趣，从而提高学习效果。教学方式：讲授法、发现法、合作学习法、阅读与表达 教学手段：多媒体辅助教学技术准备：课件、补充阅读材料、温度计、道具等。
