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。

四、说教学方法和学法指导Teaching methods and study guide
在本单元的Reading当中,文章比较长,有很多有的新单词,个别的句子非常难理解,学生在阅读当中一定会遇到一定的困难。因此,我采用了一些灵活的实用的教学方法(如Scanning and skimming method和Task-based method),帮助学生理解文章的内容,努力提高阅读课的教学效果。具体做法如下:
1、 解读标题 The Birth of a Science、 这能帮助学生快速了解文章的内容。对提高阅读效果有很大的帮助。 老师可向学生设问:What Botany?让学生思考并回答。
2、 通读课文,了解细节。老师可向学生提出问题:How many people are mentioned in the passage? 让学生快速阅读并寻找此问题的答案。
3、 深层了解,归纳课文大意。What the main idea of the passage? 让学生归纳文章的大意,从而帮助学生理解整篇文章的内容。
4、 升华主题。What can we learn from the passage? 让学生能联系实际,学有所获。
5、 让学生进行分组(Pair work/ Group work)的讨论(Dcussion),加深学生对课文的理解,进一步调动学生学习的积极性。
