设计理念：根据新课标，培养学生自主、合作、探究精神、突出语言运用能力养的理念而设计。课型：阅读课学生现状分析： 大多数的学生的英语基础一般，语言运用的能力较弱，阅读对学生来说更是难点，平时教师上课只重视了知识的传授，忽略了对学生探索、合作等方面能力的培养，通过对本课的学习，让学生更多的理解环境对人类的重要性，从而改变平时学生的一些不良习惯。一、教材分析（一）教材的地位和作用1、单元背景分析：环境是我们人类的共同拥有的，我们有责任和义务去保护它们，但随着现代工业的发展而导致的环境污染，人类对森林资源的乱砍乱伐，使得人类的生存的环境遭遇了破坏，有些野生动物也到了灭绝的地步。例如在我国北方春季出现的沙尘暴天气，持续几年的干旱少雨。在世界上别的地方发生的越来越多的自然灾害，无不说明人类对环境破坏的严重性。所以，保护人类赖以生存的环境是全世界的呼声，而且刻不容缓。2、教材内容分析这篇文章主要介绍了我国绿色长城的情况以及它对人类的重要性。由于人类对大自然环境的破坏导致了人类生存环境的恶劣，教育人类要保护自然生态环境，不要滥砍滥伐，结合课文，让学生意识到生态环境对动物的重要性，联系实际，就我们这个地方目前生态环境说说自己的看法。我们目前居住的环境其实也很不理想，一些污染影响着我们的生活质量，让学生明白保护我们的生存环境，于已于人都非常重要。3、教材重点、难点教材重点：（1）重点词语：Keep sb. / sth fromdoingin this way millions of the Great Green wallbe covered with work onin a few year timethanks toall over the worldThe more, the better point to /at（2）重点句型：Forests help to keep water from running away.The Great Green Wall is 7000kilometres long, and between 400and 1700kms wide.Was it difficult to work on the Great Green Wall.The more, the better.（3）重点语法：含有情态动词的被动语态。教材难点：（1）讨论如何采取措施保护我们的生态环境？（2）给有关部门写一封信，呼吁全社会保护自然生态环境，爱护野生动物，人人行动起来，多植树。（二）教学目标：1、语言知识目标：1）掌握并能灵活运用本单元出现的重点词汇2）掌握含有情态动词的被动语态。2、语言技能目标：通过本课的学习，培养学生良好的“听、说、读、写”的技能，使学生能运用所学知识解决相关情景中的一些类似问题，并能结合所给任务，综合运用新旧知识解决问题，在此基础上鼓励学生大胆根据自己的语言基础能力，就如何来保护我们的生存环境，改善我们的生存环境提出独特的见解。3、情感目标：1）激发并提高学生的学习兴趣，乐于接受新事物，勇于尝试体现课堂教学“主体者”的身份，积极主动参与教学各环节，成为学习的主人。2）培养学生良好的环保意识，热爱大自然，热爱动物，保护野生动物。二、教学策略本单元的主题是谈论的是森林对环境的重要以及在我国的森林的情况，教学内容能激起学生的兴趣，通过多媒体课件为学生创设更多的语言环境，激发学生主动参与的欲望。因而在课堂教学中巧妙运用教学艺术，适当安排小组讨论，使学生在轻松愉快的环境中实现更多的信息交流，让学生在做中学，在做中练，在做中巩固，从而有效地提高课堂教学效益，达到事半功倍的效果。阅读设计思路：快读(Fast Reading)精读(Intensive Reading)操练(Practising)巩固(Consolidation)。三、学习策略1）课前认真预习，利用网络收集生态自然环境对人类和动物生活质量的影响这方面的资料，以及有关生态保护信息，课后能及时巩固复习。2）上课勤思考、多动脑，掌握所学词汇，热情、积极、主动参与课堂上的各种活动。四、教学过程：(Teaching Procedures)Step Warming-upT: Ive a wonderful song, would you like to share it with me ?（理念：课前播放一首欢快的英文歌曲，渲染课堂气氛，营造英语学习氛围，使学生很快进入角色）T: Boys and girls, shall we begin our class now?
