Astronomy：thescienceofthestars教材分析
“理解”（Comprehending）部分通过五个练习题检测学生对本文核心内容的理解。练习1是对文章结构的分析以及大意的概括；练习2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；练习3提出5个小问题，考察学生的深层理解和推理判断能力；练习4让学生找出文章中出现的连接词，检查学生对文章中句型的熟悉和理解程度，同时还有助于学生在写作方面得到提高；练习5让学生回答问题并向全班学生汇报，开拓学生的思维并锻炼他们的语言表达能力。
“阅读”（Reading）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它关系到了地球的未来.
