点评：
本节课在warm-up and Lead-in 环节我设计了图片浏览的环节，通过地球上美丽景色和垃圾照片的强烈对比唤起学生对于本课主题保护地球的共鸣，同时我在这个环节预热了本课将要学习的生单词，降低学生学习文本的难度，为新课的学习做好铺垫工作。
进入文本学习后，我通过带领学生学习一段，教会学习方法后引导学生自主学习剩余的三段，有效地锻炼了学生的自学探索能力。我设计的迷你讲座环节有效地帮助学生巩固课文，在轻松活泼的交流气氛中，让学生不知不觉地加深了对文章语言点的理解和巩固。在本节课的最后，我让所有的小组合作完成环保海报，并贴在教室周围，宣传环保理念，让学生真正地跳出文本，将学习的知识运用在实际生活中。
