Professor Benos
acknowledges that eating a raw food diet may have
some positive effects: ‘A
raw food diet is high in
fresh food, which is richer in nutrients than some
kinds of processed food.
The diet also encourages
more chewing and takes
longer to digest so it is more satisfying. As a result we do not eat more than we need. ’
There exists some
scientific evidence that eliminating cooked
food from the diet is
beneficial. However,
enzymes are produced by the body to aid
digestion, whether the food is cooked or raw.

一、教学设计与说明
1. 教学目标
本课为本单元的第 6 课时，核心目标为引导学生认知并运用应用文的格式文体与写作目 的，和帮助学生理解“健康辩论”的基本概念与意义。
2.设计思路
在课堂开始，教师通过提问以及分享个人经历，帮助学生理解何为“健康辩论”，同时 引导学生举例生活中遇到的健康辩论。
首先，教师带领学生扫读文章，指出并归纳文中出现的应用文文本特点——杂志文章。 在通读全文后，引导学生用自己的语言概括健康结论，并结合教材中的表格从文中提取健康 结论。接着， 教师引导学生结合自己的生活经验来预测文中关于健康辩论的论证方法及可能 的理由。在核对文章信息之后， 归纳文中所涉及的论证方法。教师鼓励学生将文中的健康辩 论内容与亲身经历结合，并在此基础上进一步讨论文中涉及的论据、论证方法与健康贴士， 归纳并评价这些论据的种类、可信度以及重要性。
最后，教师会提供一组额外的健康辩论相关的研究数据，带领学生运用在健康辩论语境 下所学的应用文文体，撰写一个健康辩论主题的应用文段落。如果学生有困难， 教师可以引 用自己课堂开始时谈论的生活例子，提供相关研究论据和范文，引导学生梳理出结论及论据 间的逻辑关系，并以此为模板开展下一步的应用文运用练习。
3.重点难点
教学重点：基于“健康生活”的主题，理解并运用应用文的格式文体，总结归纳文中出 现的健康论点、论据和逻辑关系；
教学难点：辨识不同论据的逻辑、重要性和结论，并能用自己的语言进行文字表述。
