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。最后提出两个问题，考查学生的深层理解和推断能力。

5. Learning about Language部分首先通过英文解释帮助理解课文中的生词，然后，通过短文填空、词语分类等形式将这些词语用于一个相关的情境中。语法部分也是采用先发现后应用的学习方法。先通过到课文中找句子，让学生认识主语从句，然后，设置一个用手机发短信息的情境，让学生进行简单句与主语从句之间的转换练习。最后设置情境来复习第三单元出现的表语从句。
