高中英语 Unit 4 Global warming教案 新人教版选修6
高中英语 Unit 4 Global warming教案新人教版选修6 Ⅰ. 单元教学目标Ⅱ. 目标语言Ⅲ. 教材分析与教材重组1. 教材分析本单元以Global warming 为主线，旨在通过单元教学使学生经过思考、学习，认识到全球变暖的起因和它所带来的种种后果。
同时鼓励学生进一步阐述地球所面临的其它严重问题，激发学生的环保意识。
引导学生运用所学语言、句式表达自己对这些现象的看法，培养他们为自己的观点辩论的能力，并能运用所学知识写一篇有关环境问题的论文。
1.1 Warming Up通过直观的图片，使学生对能源的用途和种类有一个基本的了解。
让学生对当今人们开发和使用能源以及随之而来的种种影响有更深一步的思考和认识，从而为本单元主题Global warming 作了很好的铺垫。
1.2 Pre-reading是Reading的热身活动。
通过组织学生对这些问题的讨论、回答，激活他们头脑中相关的内容模式，为下一步阅读做好准备。
由于Global warming 是当今世界的一个热门话题，学生已从多种渠道对此有了很多的了解，因此教师可以在安排预习作业时让学生分组做 a project on global warming , 这样既符合了新课程的要求——体现学生的主体地位，激发学生自主学习的热情，又能得到很好的教学效果。
1.3 Reading是一篇从杂志节选的文章。
它讲述了全球加速变暖的原因——人为温室效应，后果以及人们对此的不同观点。
要求学生在理解文章大意的同时注意它的写作技巧：提出问题——分析现象——阐述各方面的不同观点——以疑问句作为总结引发读者深思，自行做出判断。
这为Comprehending 中Exercise 3的分组辩论活动留出了很大的空间，埋下了很好的伏笔。
1.4 Comprehending 包含了三大部分。
前两个部分中设计了诸多细节性的问题，旨在检测学生定位、理解细节及对文章大意的总结归纳的能力。
