课件30张PPT。教材分析 *本节课是高中英语新课标选修6第4单元的课文阅读课，课文标题为“the earth is becoming warmer-but does it matter?” 全球变暖已经是一个非常严峻的问题，日渐得到全世界的瞩目和关注，因为它关系着地球和人类的未来命运。
*高考命题的热门话题
*一个课时
学情分析 1。在情感和认知方面： 通过以前的地理、化学方面的课程，对全球变暖这个话题有一定的了解。关注意识要加强。
2。在语言技能方面：相对其他主题来说，学生在环境、气候、能源等方面的词汇是极为缺乏的，相应的英语知识也是 比较少的，所以阅读这种类型的科普文章有一定的难度。
3.学生基础一般，需要有充足的阅读时间，同时也需要合作，交流和竞争。可以在原来的基础上得到长足的进步。
教学目标 语言技能：1.能识别杂志上议论文的文体特征
2.能理解不同科学家对于全球变暖的观点和态度。
3.通过查读，跳读，列举要点，看首字母等阅读技巧，能对信息进行加工处理。
4.激发学习英语兴趣，强化语言意识，学会用英语表达观点和态度，提高学生的写作能力。
教学目标 语言知识：1.学会使用课标规定的单词和词组的用法
2.学习并掌握议论文的基本篇章结构
情感态度：换起学生对环境保护和低碳生活方式的兴趣。通过课堂活动，不断培养学生团队合作精神和竞争意识。
学习策略：资源策略和交际策略
文化意识：环境问题是一个全球性的大问题，解决环境问题靠全人类携手合作。
1.训练学生利用阅读技能技巧（略读，查读）以及文中阅读中的批判、推理和归纳能力，是教学的重点。
2.教学难点在于指导学生对课文阅读内容进行整合，再利用其进行口头讨论，表达和支持自己观点。
重点和难点 1.利用多媒体增加对背景知识的感性认识和兴趣。
2.采用任务连环套的设计和小组合作的方式，实现由梯度地呈现知识和任务，在相互构建中完成任务；有利于各个层次的学生参与，实现新课标以学生为中心，以活动为主线的教学思想。
3.上课时，老师在布置任务的时候，指导语要清晰明了；把更过的时间留给学生去阅读思考和完成任务。这样才能体现新课程思想：以教师为主导，以学生为中心。
