新外研-必修2-Unit 6-第5课时-Developing ideas
必修二Unit 6 Developing ideas What’s really green?阅读语篇教学设计设计理念：《普通高中英语课程标准（2017年版）》（以下简称《新课标》）首次使用了“大概念”一词，强调“以学科大概念为核心，使课程内容结构化，以主题为引领，使课程内容情境化”（教育部，2018）。
大概念是教学设计的核心与基础，它指导教师从更上位的视角出发，整合教学内容，规划教学和评价活动。
对学生而言，大观念可以帮助他们在零散的知识之间建立关联、形成结构，为推动整合性的学习创造可能，指向深度学习（李刚、吕立杰，2018）。
因此，本课是基于主题语境——“人与自然，”在单元大观念——“正视全球面临的环保问题，了解先进的环保理念，增强环保意识，践行绿色生活方式，树立共同关爱地球，保护环境，与自然和谐相处的价值观”的引领下而进行的教学设计。
学前分析：本课是新外研版（2019）必修二第六单元Earth First第五课时Developing ideas - What’s really green.单元主题：人与自然主题语境：关爱地球、保护环境单元主题意义：正视全球面临的环保问题，了解先进的环保理念，增强环保意识，践行绿色生活方式，树立共同关爱地球，保护环境，与自然和谐相处的价值观文本分析：【what】本文语篇类型为报刊专栏文章，介绍了生活中常见的关于环境保护的几个认识误区，引导学生对所谓的生活常识持批判的态度。
【why】通过该语篇的学习，引导学生重新审视以前的生活常识，建立新的、正确的环保理念，提升思维品质。
【How】本文通过“原因——影响——措施”的逻辑关系阐述自己的观点，改变读者不正确的环保理念。
学情分析：学生经过前四课时学习，对环保理念、践行方法都有了基本的了解，能够初步判断所谓的生活常识的正误，但不能清晰、有条理的阐述理由。
教学目标：通过本课的学习，学生能够：1．辨别正确的绿色生活理念，正确看待所谓的生活常识。
