Unit5 Using Language2 名师教学设计
Reading for writing: Chemical farming versus organic farming
【语篇研读】
该阅读文本是using language的第二部分以“评估化学耕作和有机耕作(evaluate chemical farming and organic farming)为活动主题,介绍了化学耕作和有机耕作的两种特点,分析了各自的优缺点,最后的结论是人类如果想要既吃得饱又吃得健康,同时保持环境的可持续发展,还有很长的路要走。在文本结构上,采用了先分后总的信息组织方式。本文使用了说明、举例、对比等写作方法,并运用了大量的语篇标识词,体现了文本较强的逻辑性和所说明内容的全面性。学生可以在文中找到不同的证据,发表自己的看法。“吃得饱”和“吃得好”其实是相互制约的问题,启发学生辩证思考农业耕作的方式。
【设计思路】
立足发展学生思辨能力和写作能力为设计目标,紧扣主题意义,贯通落实了从读到写的具体任务。通过自主,合作,探究等学习方式,引导学生认真研读语篇,鼓励学生积极展示自我,培养学生自主学习能力,为学生学会学习创造条件。
阅读环节,引导学生理解、分析文本信息。先快速阅读整篇文章,找出what is chemical farming and what is organic farming的答案,并画出结构图,梳理文本的篇章结构。然后细读文章,以自主阅读方式,按照 “Benefits-Problems-Solutions”的逻辑层次,通过表格帮助学生梳理并归纳总结文本的细节信息,并且帮助学生提高写作布局的能力,在这一过程中,引导学生聚焦语篇标记词,掌握丰富的语言表达,让学生可迁移运用到之后的议论文写作中,增加表达的逻辑性和说服力。
写作环节是对学生思辨能力的训练,读是为写而服务的,输入的知识最终都要落实体现到出口任务。该环节首先让学生通过小组讨论列举两种耕作方式的优缺点,培养学生的批判性思维,然后要求学生先根据阅读环节的讨论结果以及给出的要求完成提纲,写作前列出较为详细的提纲能帮助学生更好地整理内容和思维,提高写作效率。然后再组织成篇,并提示学生使用所学的语篇标识词来连接句子,构成语篇。然后同学之间依据评价清单进行互评,时间足够的话还可以让学生当堂展示写作作品,老师提出相应的评价。最后根据同学和老师的评价,修改自己的文章,最终达到提升学生深度思考和探究问题的能力。

[Sample writing]
In my opinion, organic farming is preferable to chemical farming because it has numerous benefits. To begin with, organic food is generally more nutritious than food grown with artificial fertilizers. In addition, it is beneficial to our health. In fact, it contains much more essential minerals, for instance, vitamins. Finally, what attracts consumers most is its tasty flavour.
However, as for chemical farming, it produces food with less flavor and nutrition, which is essential to people. Plus, chemical farming kills not only bad but also good insects and thus damages the land.
Therefore, I hold the belief that organic farming brings us more advantages and is more environmentally friendly.
