A Teaching Plan
课题：人教版选修六Unit4 Global Warming Reading
一. 教材内容分析
本单元中心话题为“全球变暖”，旨在通过单元教学使学生学习、了解、思考全球变暖的起因和可能带来的后果，并针对该问题探讨可行性措施。

Reading局部说明了全球变暖的起因、后果以及人们对此的不同观点。

二. 学情分析
学生语言根底不扎实，尤其是词汇的局限直接影响了对文章的理解，所以要求学生做好预习工作，减少语言障碍。

地球变暖在其他学科及日常生活中都已有所了解，是学生比拟熟悉的话题，但这是一篇杂志文章，语言比拟正式且复合句较多，对于根底较弱的学生来说有一定的难度。

所以强调学生要有互相合作互相监督和互相学习，从而促进互相进步。
