设计意图：运用自己制作张贴画的形式拓宽学生的思维，将课堂中的知识延伸到课外。
反思：本节课笔者曾经在不同的三个学校：多个班级讲授过，感受到最成功的一点是，让学生在教师精心创设的学习环境中主动地感知语言，发现语言学习现象，用从娱乐节目中得到的灵感来创设真实的教学录像。学生在不知不觉中参与到了一个个真实的课堂教学活动中。在课后笔者对授课班级的学生进行了调查，学生们大多数都掌握了本课的单词和所学的句型，感受到这样的课都很喜欢。同时本节课也于2005年11月参加了海淀区第三届世纪杯评优课，获得了英语学科一等奖。本节课的教学设计也被选入海淀区第三届世纪杯优秀教案集。同时教学中还有些不尽如人意的地方，例如，在听力的评价的环节，教师应该给与学生的范围在广泛一些。可让学生对凡是满意自己的答案的同学都画上一个五角星等。
