教材

分析

What：三段谈论发明的对话。第1段对话谈论常见物品的发明时间， 第2段谈论一些有趣小发明的用途，第3段是关于拉链及其用途的对话。

Why：1a引导学生讨论呈现的发明物，为1b听力做准备；1b 和 1c训练一些伟大发明物品的发明时间，开阔学生眼界，丰富阅历。 2a-2c通过谈论一些有意思的小发明，进一步训练听说技能和语言表达能力，培养学生的创新意识；2d对话是一项小而有用的发明--拉链的发明及广泛用途，让学生熟悉周围经常使用的发明物，养成勤于思考，善于总结的好习惯。

How：围绕单元话题“说明”，分别就发明的发明时间，发明者和用途展开语言听力训练。从语法结构上，复习巩固已学过的被动语态；从语言结构上，训练对发明者和发明用途提问的句型及其回答句式结构: Who was it invented by?It was invented by...；从情感结构上，培养学生对新生事物的发明产生兴趣并进行相关讨论。
