爱迪生是众所周知的发明家。
学生了解的比较多。
通过游戏来教语法既能活跃语法死气沉沉的课堂，又能让学生乐于接受，牢记于心。
用火车和飞机的发明来呈现学生知道的人
比较多，因为社会书上有着方面的知识。
听力材料生词很多，先呈现新单词扫除一些障碍。
对话中复杂、难读的人名，给学生造成很大的障碍。
教师可以有意识地替换成班级学生的名字，学生朗读更容易，学习气氛更活跃。

建议与说明
学生仔细听并猜测他们的发明。
这个环节能够检查学生完成作业的情况，巩固第一课时的重要语言点，以游戏娱乐的情景完成课前复习。
让学生在自己的身边寻找更多的发明就更能体会什么发明是有帮助的，什么发明是惹人烦的。
学会合理应用身边的发明的事物去解决生活中的难题。
学生可以根据自己的兴趣，通过查书籍、上网等形式，查找相关资料，介绍发明者、何时发明的、有何用途等。
