* Reading 通过任务型阅读，培养学生的阅读能力和 概括能力。 2. 教学生热爱发明，勇于思索和探究。 本节课以Inventors and inventions为话题，让学生了解发明和发现的区别，学习发明家的成功事例。Warming Up 提供了一些科学家及其发明创造的图片，直接导入文章主题。 Reading部分，主要是让学生从整体上去把握文章结构:了解发现问题（snake trouble）、分析问题（products that might help）到解决问题（remove the snakes）的全过程，并介绍了专利申请方面的一些知识。 通过快速阅读和细节阅读，既让学生从整体上理解全文，又让学生从细节上深层次加深对文章重点和难点把握。设计问题分层进行,使得不同层次的学生都有话说,这样既能够培养学生阅读思维能力，又能提高学生口语表达能力，课堂效果明显提高。 1.Do you know any inventors and inventions? let us appreciate a video to know some folk inventions in china. 因您的存在而有力——发明创造中国梦 Zhang Heng seismograph invented Cai Lun ↓ papermaking Ben Franklin Lightning is electricity discovered radium Madame Curie discovered the New Continent Columbus Please tell whether the following are discoveries or inventions.
