Learning about Language优质课教案内容

Unit 3 Inventors and inventions

I．教学内容分析

本单元的中心话题是“发明家与发明”，具体涉及“发明与发现的区别”、“发明产生的过程”和“申请发明专利的条件”。语言技能和语言知识都是围绕“发明”这一中心话题设计的。只要人类在地球上生存起，发明就是人类生活的一部分。每一项发明都是每一个人在解决问题和应某种特别的需求，经过不断的科学实验的结果。因此发明和发明家不是新东西，只要大家勤于思考、发挥想象力和创造力去解决问题，就可能有所发明。

Warming Up部分提供了一些图片，要求通过小组讨论弄清“发明”和“发现”的区别。因为这部分的问题很有趣且具富有挑战性，所以能调动学生讨论的积极性，达到热身的效果。

Pre-reading部分让学生了解发明家为了让其发明得到认可所必须通过的六个重要的程序，让学生意识到发明和科学过程之间的联系。

Reading部分是一篇记叙文。故事讲的是一个女孩如何通过多次尝试最后成功地把在她母亲家院子里安家的一窝蛇捉住并放归大自然，她的捕蛇技术申请了发明专利。学习这篇短文，让学生更进一步了解发明的六个重要程序并说明发明不一定是非常重要的东西，有时它们是一些细小的解决问题的方法。

Learning about Language部分突出了词汇和语法的学习与训练。本单元的语法是理解和掌握过去分词做定语、表语和宾语补足语的用法。

Using Language部分包括了听、读、写三个部分的内容，阅读和听力材料分别介绍了电话发明家亚力山大·贝尔以及当今英国发明家詹姆斯·戴森的故事。通过描述亚力山大·贝尔为什么和怎样最终完成了他的最著名的发明：电话。学生可从中了解一个真正的发明家发明的过程。并通过操练打电话和写求职信进一步训练学生读和写的能力。

Learning Tip部分告诉学生不要害怕失败。成功的发明家往往要经历很多次实验的失败。然而如果继续犯同样的错误，那明显是错误的，因此，提醒学生要注意这一点。
