Unit 6 Keep our city clean

说课

本节课以歌曲导入新知，歌曲中两只自由欢快的小鸟把学生一下子引领到一个干净、优美的自然环境中。教师通过与学生一系列的对话互动，逐步引出本课话题：城市环境问题。接着，通过一组城市图片，让学生展开对城市A的讨论，让学生通过观察来描述干净、整洁的城市A。当学生们正沉浸在美的感受中时，一组不协调的城市B照片适时展现出来，与之前的城市A形成鲜明对比，让学生从感官上对dirty和messy产生联想。学生从学过的句型I can see … 开始探讨，在老师的引导下逐渐转用新句型 … make(s) … dirty/messy进行讨论，分别谈论了河道、街道和空气的污染源。

在课文学习部分，教师将这篇对话分成了两个部分。第一部分，先要求学生带着两个简单任务观看课文视频，旨在对课文第一部分有个初步印象。然后，让学生自读课文，对课文作进一步了解，这次学生可以找出该部分的中心句What makes our city dirty? 并在文中逐一找出答案。在学生完全解读文本的基础上，可以让学生操练教材第60页上的Ask and answer，该环节巩固了第一部分出现的句型Is the … clean? What makes … dirty? 课文第二部分是先用听力练习的形式呈现的，让学生带着What can we do to keep our city clean?的疑问听该部分，教师通过PPT呈现句型、图片及关键性动词put, walk, move, plant，让学生能将单词组词，让学生观察图片和所给的提示单词，进行独立思考并找到问题的多种答案，培养学生的语言组织能力和自主学习的能力。然后通过教材第60页上的练习Think and write，巩固这部分内容。分段学习完课文后，让学生通过不同形式的读来完整解读课文，教师在这个过程中纠正和规范语音语调，指导学生朗读。
