高一英语：The Birth of a Science说课稿

一. 说教材(Textbook)

在人教版高一英语的下册的Unit 19，曾经谈论过一些关于农业的话题，学生对中国早期的出名的农业家贾思勰有了一定的了解。人教版高三英语的Unit 4这个单元以Green World 为话题，让学生初步了解一些植物学方面的内容，如植物的分类、栽培以及植物学的发展的历程等等;语言技能和很多的语言点几乎都是围绕介绍绿色世界这一中心话题而展开的。要求学生能够运用所学的内容对相关话题进行流利的表述。

在READING部分，介绍了植物学正式成为一门科学的历史形成过程。重点介绍了两个为植物学发展做出过卓越贡献的重要人物林厄尼斯与班克斯。他们以独特的归类的方式对植物进行分类，从而征服了整个世界。

在POST-READING 部分，针对READING部分的相关内容设计了5个练习。第1个练习以选择填空的形式考查学生对课文细节内容的了解。第2-5小题以问句的形式进一步考查学生对课文重点内容的了解。
