8.作业布置 Work in pairs to collect information about one of the environmental problems(air pollution, noise pollution, water pollution...)
9.教学反思 在阅读第一课时后，学生对于亚马孙热带雨林相关内容有了一定的了解。因此在上周末，我布 置了学生观看一个无字幕的视频，并根据上节课所学的知识给视频配音。学生的作品给了我很 大的惊喜， 也确实反应出他们进行了有效的团队合作。另外学生在本堂课上也进行了小组讨论， 对同学的作品进行评价，有效地培养了他们的批判性思维能力。从学生创作的文本中，我挑选 了个别句子，指导学生了解说明文当中可能用到的写作手法之一——作比较。后半节课也没有 按照传统去分析课文知识点，而是进行了课外的联文阅读。所选的课外文本也和课本一样来自 纪录片的脚本， 通过相关话题的拓展， 同为说明文体裁的文本解读， 带领学生了解说明文的结构， 更深刻地体会环境保护的重要性。个人认为， 这节课比较成功， 也完成了预先制定的教学目标， 当然学生还需要更多相关知识的输入才能更好地表达自己地观点以及对他人作品进行更全面更 细致的点评。
