、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；3 、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；4 、作为情景创设，导入新课，为下面的教学活动做铺垫。
