we’re trying to save the earth!一、教材分析本课时中 2a-2c 也是一种完整的听说任务链。2a 的听力任务相对简单，重要是对所听材料内容的整体理解。2b 重要训练学生捕捉关键信息的能力。2c 则是针对上面的听力内容做的口语训练。2d 的对话与主题紧密相连，谈论处理污染的措施。二、学情分析这一课的听力是对上一节课内容的延续与拓展。由于上一节课的铺垫，学生对话题熟悉，因此听力部分并不难。不过，九年级的学生不喜欢发言，这对我怎样上好2d 的对话训练提出考验，鼓励与前面的知识铺垫是必不可少的。三、教学目的1. 语言知识目的：1) 能掌握如下单词及短语：coal, ugly, cost, wooden, plastic, takeaway, bin 2）句型 The air is badly polluted.2. 情感态度价值观目的：有环境危机意识，学会关注环境保护环境。四、教学难点教学重点单 词 ： coal, ugly, cost, wooden, plastic, takeaway, bin 句型：The air is badly polluted.教学难点怎样用英语体现保护环境的措施措施。听力能力的提高。八、教学过程设计教学过程Ⅰ.
