17、h in the bin.Rubbishmake(s)the riversdirty.We canplant more trees.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
18、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
19、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。在语言输出部分，设计了复述课文和制作海报的环节。制作海报是学生喜爱的活动，通过这个环节，即巩固操练了新授内容，又联系了生活实际，让他们意识到环境卫生的重要性，要从身边做起，创造美好的生活环境。本节课的几个主要关注点：1. 关注学生对课文的整体感知和细节信息的获取。2. 关注学生的朗读，注重指导。3. 关注学生的合作性学习。4. 关注学生的阅读习惯，指导学生找关键词、句，根据上下文的意思猜出生词的意思。
