新课标高一必修3 Unit 4 AstronomyThe Scienc人教版新课标高一必修3 Unit 4 Astronomy The Science of the Star--教案5Unit 4 Astronomy: the science of the stars 教材分析和教材重组教材分析本单元的主要内容是边缘科学、地球生命的起源，万有引力、黑洞和太空旅行等天文学知识。
通过本单元的学习，培养学生对科学的兴趣，激发学生探究科学的热情。
1. Warming Up部分共有三组问题，第一组问题引导学生讨论边缘科学(Frontier Science)，即以两种或多种学科为基础而发展起来的科学。
例如，生物化学是以生物学和化学为基础的边缘科学。
第二组问题探讨科学研究的方法。
第三组问题让学生思考要成为真正的科学家所必须掌握的技能。
2. Pre-reading部分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。
学生总喜欢听故事或讲故事，在探讨生命的起源的科学道理之前，让学生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。
3. Reading部分讲述了地球上生命的起源。
水的形成使得地球有别与其他星球，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。
文章最后讲述的现象发人深省：The earth may become too hot for the lives on it.它关系到地球上生命的未来。
4. Comprehending部分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哪些条件?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。
