Unit 9 Save the Planet
Lesson 25 Going Green
教材分析
本文是一个介绍性的语篇，年仅15岁的牛津男孩Jim介绍了他们一家在日常生活中为保护环境所做的点滴努力。本文的主旨在于介绍一个家庭环保的范例，宣传“绿色生活”的观念。本文的逻辑性很强，Jim在介绍他们家的做法前先提出了他发现的环保方面的问题，一是人们制造了太多垃圾，二是过度用电。前者会造成土壤污染和过度消费（不断买新的东西）。后者会造成空气污染，从而使人们的健康状况出现问题，并导致全球气候变暖等。然后他针对这些问题提出了解决方案，即循环再利用、自给自足、减少电器的使用、减少汽车的使用等。这种解决问题式的写作手法条理清晰，能够很快让读者抓住文章的脉络。
