14、e so much Not cut down Not use too muchSave and reuse Save Paper bagsGlass bottles说课本课生词较多，且不好理解。所以我把几个较难理解的物质类名词拟人化为五个朋友，拉近和学生之间的距离，使他们对其产生兴趣。在导入阶段我把这五个朋友做成一首歌，不仅活跃了课堂气氛，而且让学生通过哼唱对这几个单词有初步的概念，为接下来的学习做铺垫。学习完生词后，让学生通过谈论几种物质的用处来学会使用 use to 句型。通过观看地球的信的视频自然引出本单元课题 Protect the earth.在课文学习中，首先通过让学生对课题提问让
15、他们学会带着问题进行阅读。对学生提出的问题进行梳理，提炼出 what, why 和 how 三个贯穿全文的问题。首先让学生速读课文，找出问题 What should we do? 的答案。接着指导学生细读第一部分，关注细节。通过任务让学生了解本段主要内容，同时引导他们关注如何提出建议和陈述原因。在阅读中，注意对学生的读法指导。在本段中，我设置任务引导学生通过上下文猜出生词的意思。通过第一段的学习，学生对文章结构有了初步的了解，知道该从哪些方面去寻找信息，所以可以适当放手，让他们尝试自主阅读，然后通过判断来验证自己的阅读结果。到了三、四两段，学生已经完全拥有自读的能力，所以我让学生自己阅读并完成一个报告。然后让他们依次汇报，完成表格。通过这样一个信息差的活动，锻炼学生的听说能力。在读后阶段，我制作了一个苏州的视频，让学生通过观看视频找出生活中不太环保的行为，用目标语言提出建议，使他们学会把目标语言运用到日常生活中。
