本课件是为仁爱英语九年级上学期Unit2 Topic1 Pollution is harmful to people’s health. Section B编写的教学课件。本课通过老奶奶居住环境的恶化展开，在和康康的生动对话中引导学生学习含有since 和for的现在完成时，并了解现在完成时与一般过去时的区别，鼓励学生掌握直接引语和间接引语的转换方法，从而能够更加有效地参与课文对话的讨论。情感上注重培养学生对老年人的关心和爱护并进一步认识污染给生活带来的危害。
复习----①音乐欣赏（幻灯片1。资源从“仁爱教育网”相应位置下载。）
②和同学们看图片，复习讨论污染的种类，发生地点以及危害，可以让同学们讨论生活中的污染问题以及如何解决。（幻灯片2、3）
呈现----通过展示图片和学生一起讨论并回答列举问题（主要以学生个人感受为主），其中区别出重点生字词，做适当讲解。（幻灯片4-7）
巩固----①播放1a录音，引导学生先看问题，带着问题有目的地听录音并回答问题。在这个环节中引导学生巩固刚学过的部分新单词以及学习巩固含有since 和for的现在完成时。（幻灯片8、9）（幻灯片8。点击幻灯片上面的影片实现超级链接，链接内容为P27-1a的动画。在听力练习中可以点击动画中的title键消去字幕，增加难度。点击右下角的小喇叭再听一遍，然后核对答案。）
②这个环节分为四个步骤（幻灯片10-23）
a.让学生分角色表演对话并找出康康的问题。
b.练习转述康康的问题，每个转述需要引导学生分别关注语序、时态、人称、特定单词的变化以及特殊疑问句和一般疑问句的转换区别。
c.展示老奶奶对于环境的描述及抱怨，练习陈述句的直接间接引语转换。
d.完成1b。
练习----①完成2。（幻灯片24-26）
②对刚学习的转换方法进行笔头练习。（幻灯片27）
总结与结束----（幻灯片28、29）
综合探究活动---- 可以让学生以三人一组的形式根据场景比如医院，家，商店等排练简单的小对话。下一节做展示并复习直接、间接引语的转换。这个活动教师可以口头安排学生准备，幻灯片没有展示。
