一、学情分析
（一）学习者分析
1、一般特征：
学生基本上来自农村，英语水平参差不齐，学习压力大；学习策略与方法不合理，有的学生还不喜欢英语。

2、学习风格分析：对于高中生来说，学习的习惯和方法还是局限于较为死板，习惯于题海战术，很
少有自发的对感兴趣的课题的研究或学习；
学生习惯于上课认真听老师讲解，较少地参与主动地学习，一直是较为死板地学
习，老师激发学生兴趣，使其主动融进课堂学习。

3、初学能力判断;
既一个学期的高中英语学习后，学生的英语水平能力有提高，但还需继续努力；关于必修二已经学习了第一、二单元，学生基本可以接受第三单元的学习任务，
前提是必须认真融入由教师带领的学习氛围中。

（二）教材分析
本单元以世界性的体育盛会──Olympic Games 为话题，旨在
通过本单元的教学，
使学生了解奥运会的起源、宗旨、以及古现代奥运会的异同。

学会用英语表达自己的兴趣爱好以及如何向别人推荐某一种爱好，同时培养学生对体育运动的爱好。

二、教学目标
课表内容：
（一）教学模式
关于第二单元本环节——reading部分，采用教学问答模式、课堂授受模式、指导自
学模式、合作交流模式以及探究学习多种模式交叉运用。

（二）教学策略
主要是使用替代式教学策略，使学生在短期内学习许多内容，提高教学效率。

其中
穿插问题引导方式，从而克服单一的替代式教学策略的不足（三）教学方法
以语言形式获得间接经验的方法为主，通过教师和学生口头语言活动及学生独立阅
读书面语言为主，其中使讲授法、谈话法、讨论法和读书指导法交叉使用。

四、教学平台
以多媒体课件演示为主，辅之以少量板书，即多媒体课件教室的教学环境。

五、教学计划
本单元用6课时
第一课时: Warming up and listening 第二课时: Speaking 第三课时: Reading 第四课时: Reading
第五课时: Language study
第六课时: Integrating skills
（注：本课件为教学计划中的第三课时）
六、教学动力和动机
关于第三单元本环节教学，教师通过展示学生普遍关注的或喜欢的图片调动学习兴
趣，并且共同讨论学习各种有趣的运动调动学生学习积极性，并告知学生在reading后有课堂测验，从而使学生感到较小的压力，促进学习积极性，进而完成教学任务和教学目标。

七、教学具体环节
（一）课件第一部分
以上图片作为本课时教学的第一屏
1、以Microsoft PowerPoint 2012版本“生如夏花”为主题的模板，并且包括后面的十几屏都继续使用本模板，使之成为一个整体，体现“青春”、“活力”、“激情”、“运动”等含义，不仅与本单元主题——“奥运会”精神相契合，并且为学生所喜爱，使之激发兴趣，从而更好地投入学习中；
2、使学生树立这样的思想，即青春奥运，激情的梦想在奥运（运动）、在学习，时刻充满激情，乐观积极向上地面对每一天，进而
达到教学目标的情感价值观这一目标，把教学思想和目标贯彻整个教学过程。

（二）课件第二部分
主要有2008北京奥运会、奥运五环和奥运精神为内容，包括多媒体课件第二、三、
四屏
以上图片作为本课时教学的第二屏。

1、给学生展示一幅2008年北京奥运会的主题馆鸟巢的矢量图，让学生自由发挥讨
论关于北京奥运会的任何话题任何事件。

此环节应控制在5分钟左右，充分运用合作探究学习；
2、讨论结束后，教师应该加以评价，并且补充学生讨论话题的内容，丰富学生对
北京奥运会的了解，激起学生学习兴趣；
3、作为情景创设，导入新课，为下面的教学活动做铺垫。
