浙江省平阳县金凤高级中学高一英语unit4《the science of the stars》教学案
Unit4 Astronomy: the science of the stars I单元教学目标III.教材分析和教材重组:1.教材分析:本单元以astronomy: the science of the stars, the development of life, space travel and gravity为话题,通过本单元的几篇阅读材料使学生对以上问题有所了解,并通过文章中的一些探讨性的问题,比如,The earth may become too hot for the lives on it. Then what will our future be? 使学生更好地了解我们的地球和我们的生活环境,并引发对“地球的将来如何”的热烈讨论,通过这些讨论会激发学生对天文学了解和探究的强烈兴趣。
通过讨论登月球需要的物品和可能遇到的困难学会提出问题和解决问题的表达方法,并能就此写出一篇表达合理清晰的短文。
1.1WARMING UP以讨论的形式通过三组问题引导学生讨论边缘科学,讨论科学研究的方法以及要成为真正的科学家所必须掌握的技能。
1.2PRE-READING主要让学生弄清楚什么是科学思想,什么是宗教信仰或文化传统。
在探讨生命的起源的科学道理之前,让学生以听故事或讲故事的方式,交流一下有关宇宙的起源的种种传说,既有趣味性,又能调动学生的相关知识,激活学生的思维。
1.3READING 讲述了地球上生命的起源。
水的形成使得地球有别于其他星球,它使得地球上生命的诞生成为可能。
科学家认为,地球上的生命首先诞生于水中,上百万年后,陆地上才长出绿色植物,随后出现了陆栖动物和水陆两栖动物。
最初的动物靠孵化繁衍后代,后来出现了哺乳动物,人类也随之诞生了。
文章最后讲了令人深省的问题:The earth may become too hot for the lives on it.1.4COMPREHENDING通过四个选择填空题检测学生对本文核心问题的理解:地球上生命的起源和延续需要那些条件?随后通过排序的方式帮助学生弄清本文的行文线索,也就是地球上生命的起源和发展历程。
