天添资源网 http://www.ttzyw.com/‎ Unit 9 Save the Planet Lesson 25 Going Green v◆ 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。‎ ◆ 教学目标 ‎【知识目标】‎ 根据获取的信息，运用学到的有关环保的词汇和语言进行采访交流。‎ ‎【能力目标】‎ 通过阅读，获取英国的一个家庭为保护环境所做出的努力的信息。‎ ‎【情感目标】‎ 通过阅读，增强学生“保护环境、人人有责”的意识。‎ ◆ 教学重难点 ◆ ‎【教学重点】‎ 本文的重点是文章的脉络，比如文章提到的问题和解决方法。 【教学难点】‎ 天添资源网 http://www.ttzyw.com/‎ 天添资源网 http://www.ttzyw.com/‎ ◆ 课前准备 ◆ 本文的难点是让学生在语境中猜测词义，以及有关环保的语言和对绿色生活的讨论。 ‎ ‎1. 课前准备：调试光盘与课件、给学生分组、为学生布置预习作业等； ‎ ‎2. 教具学具：光盘、大卡片等。‎ ◆ 教学过程 Step1.
