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思路清晰的短文。
1.1 WARMING UP以讨论的形式通过三组问题引导学生讨论边缘科学,讨
论科学的方法以及要成为真正的科学家所必须掌握的技能。
1.2 PRE-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。
1.3 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.
1.4 COMPREHENDING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。
1.5 LEARNING ABOUT LANGUAGE分词汇和语法两部分。其中,
Discovering useful words and expressions通过英文释意,短文填空,词语分类和
单项选择等练习让学生在语境中掌握和运用词汇。Grammar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,设置一个用一手机发短信息的情景,让学生进行简单句与主语从句之间的转换练习。最后设置情景来复习表语从句。
1.6 USING LANGUAGE由Listening、Reading和Speaking and Writing三部
分交互组合而成。指导学生在听和读的输入性学习之后,完成说和写的输出性应用练习。Listening的内容介绍三位科学巨匠。不仅通过听力填表的形式训练学生捕捉细节的能力,还通过四选一的方式帮助学生找主题思想。在解释对与错的过程中,教师可以适当的介绍一下概括主题的方法。Reading是一个科幻小故事,通过作者和作者的朋友乘宇宙飞船登月球的经历,介绍了重量、失重和地球引力等科学道理。Speaking 以Visiting the moon为话题,要求学生讨论登月球需要携带的物品和在月球上可能遇到的困难。Writing要求学生找出登月球可能遇到的三个困难并找出克服这些困难的方法。在听说读写综合提高的同时,培养了学生的创新意识和实践能力。
2. 教材重组
2.1 将 Warming up、Pre-reading、Reading 和Comprehending四部分整合在一起上一节阅读课。
2.2 将Leaning about language和 Workbook中的 Using Words and expressions
以及 Using Structures整合在一起上一节语法课。
2.3 听力Using language中的 Listening与 Workbook中 Listening和Listening
task三部分话题较为接近,其中Listening部分是介绍三位对地球引力的认识做出巨大贡献的科学伟人。在提高听力的同时,为下文的Reading部分作了铺垫。Workbook中 Listening是关于轰动一时的航天英雄杨利伟的故事。通过听力练习,让学生了解作为宇航员所需要哪些素质。而Listening task中的听力则是向学生展示space travel 的潜在价值。既然三部分都在谈论与Astronomy有关的内容,所以放在一起处理比较合适。
2.4 把Using Language 中的Speaking 和 Workbook 中的 Talking 和
Speaking task放在一起整合成一节口语训练课。这几部分涉及到本单元的功能句,指导学生学会如何思考需要的东西,怎样给别人以指示以及如何向别人问问
题。
2.5 泛读 是把Using language中的Reading和Workbook中的Reading task 整
合在一起。这两部分利用science fiction story向读者解释gravity和black hole.
2.6 写作练习是把Using language中的Writing 和Workbook中的Writing Task
以及Project整合在一起上一堂写作练习课。
