一、课例背景
本課例由广西省融安县高级中学吴佳玲老师执教,是校内高二阅读公开课,授课时间40分钟。
二、教学分析
1. 教学内容
本课例选取人教新课标版高中英语必修6 unit4 reading(说明文),文本语言难度较大。描述全球变暖起因,如何应对全球变暖问题以及两个专家对全球变暖意见和看法。课时的教学重点是认识全球变暖产生的后果;鼓励学生表达对全球变暖的看法和应对措施。
2. 学情分析
授课对象为高二年级B层次的学生,基础弱,本课内容贴近生活并涉及其他学科相关知识,可在网上搜相关话题、文章和图片。学生有兴趣,为本课学习提供背景知识支架。
3. 教学目标
(1)熟悉与全球变暖和表达观点的词汇:burning of fossil fuels、human activity、greenhouse gases等,句式:I would like to suggest that we’d better...I think it would be wise to 等。(2)了解全球变暖的起因后果,启发学生应对全球变暖。(3)通过讨论培养批判性思维,激发社会责任感和积极的生活态度。
