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：
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 is Botany?让学生思考并回答。
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。
深层了解,归纳课文大意。What is 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。
升华主题。What can we learn from the passage? 让学生能联系实际，学有所获。
让学生进行分组（Pair work/ Group work）的讨论（Discussion），加深学生对课文的理解，进一步调动学生学习的积极性。
