Unit 18 Inventions I教学内容分析 素质教育就是要培养学生的创造性思维能力，激发学生的创新意识。本单元以“发明”为话题，介绍了对人类历史发展起重要作用的发明创造。内容具体包括：科学技术发展、人的思维模式以及对发明的新认识等，旨在通过本单元培养学生的创造性，开发学生的非智力潜能。 Warming up部分设计了三个问题，通过列举四个与日常生活密切相关的“发明”来引起学生的兴趣，让学生感到其实发明无处不在，同时也激起了学生智慧的火花。 Listening部分提供了四个发明：发明(一)是使用水而不是汽油的汽车；发明(二)是会飞的自行车；发明(三)是一台可以预见未来的机器；发明(四)是万能翻译笔。针对这四个发明，要求学生通过小组讨论，分别以发明者的身份述说自己所发明的物品的功能以及有用的理由，然后选出一位同学扮演专利局官员对四项发明进行依次提问，最后决定这些发明在实际生活中是否真正具有实用性。这个部分可以让学生在情景对话中学会运用相关的短语表达自己的想法，提高会话能力。 Pre-reading部分是阅读的热身活动。该部分提出了三个问题：第一个问题是问学生创造能力是否可以学习；第二个问题是问一个发明者是否必须拥有非常高的智商；第三个问题是问人们如何产生创造新发明的点子。这三个问题可归纳为发明与智力的关系，其目的是拓展学生的思维，激起他们阅读兴趣，为下文做好铺垫。 Reading介绍了一些伟大的思想家创造新发明的一些思路和思维模式，主要有：框外思维、换个角度看问题、联想和不断试验。本部分在介绍这四种思维模式时，运用实例和形象的语言，使内容更加丰富、生动、具有说服力，让学生更有兴趣学习。学习这篇文章更能够激起学生的创造意识，有利于培养他们的创造性思维，对以后的学习有很大帮助。 Post-reading设计了两个部分。第一部分是根据学生对课文的理解，要求学生对七个句子的正误进行判断，如果有错，加以改正。这一部分旨在检查学生对课文的理解程度并加以巩固。第二部分是在学生理解Reading中所提及的四种思维模式的基础上，给出具体实例，让学生排列顺序。这两部分的共同目的是检查学生的理解程度，诱导学生联系实际，拓展思维。 Language study分为两大块内容。第一块内容是词汇练习。该部分设计了两个练习：(1)单词形式转化，帮助学生掌握构词法以扩大词汇量；(2)介词填空，强调了课文中的重点知识。第二块内容是语法，复习定语从句，设计了，一定形式的练习，让学生加以巩固，并且选用了谜语题，生动有趣。 Integrating skills部分包括阅读和写作两个任务。阅读部分主要介绍在科技领域中所应用的一些形象贴切的比喻，使学生更容易理解一些抽象的概念。写作部分提供了两个题目：未来的电子计算机和向十九世纪的人介绍电脑，由学生选择写其中一个。 Tips介绍了学习英语的策略。告诉我们可以运用联想、比较、图示以及分析错误等方法进行学习。 Checkpoint 18一是简单归纳了本单元的语法重点定语从句；二是要求学生掌握一些用来描述发明的词汇和短语，并要求找出一些能描述一个发明的多种用语。本部分对本单元的内容进行了反思和总结。II教学重点和难点1教学重点 (1)本单元的生词和短语。 (2)限制性定语从句和非限制性定语从句。 (3)学会描述各种发明及其作用。2教学难点 (1)激发学生的创造兴趣。 (2)如何提高学生的概括能力。 (3)学会正确运用定语从句中的关系副词和关系代词。III教学计划 本单元分六课时： 第一、二课时：Warming up，Pre-reading，Reading，Post-reading 第三课时：Listening，Speaking 第四课时：Integrating skills(Workbook)，Listening(Workbook) 第五课时：Language study 第六课时：Integrating skills IV教学步骤 Periods 12 Warming up，Pre-reading，Reading，Post-reading Teaching Goals：1To learn some basic knowledge about inventions in the 20th century which have changed our modem life so much 2To get Ss to grasp the main idea of the passage and help them to understand the passage better3To help Ss to learn to be more creative4To learn some useful words and expressionsTeaching Procedures：Step 1Warming up 1Lead-in(Class work)： Show pictures of Four Great Inventions of ancient ChinaGet Ss to talk of the Four Great Inventions of ancient China and ask some of them to call them out with the correct names China has a history of 5000 yearsIn history，Four Great Inventions stand out in the hall of glory，which we are most proud ofThey are the compass，paper，printing and gun-powderIt shows that China led the world for centuries in science and technology in ancient times2.Brainstorming： Let Ss tell of the pictures of inventions in the 20th century and let them list what inventions they can think ofwhich are invented in the last century In the first twenty years： In the 1920s： In the 1930s： In the 1940s and 50s： From 1960s to 80s： In the last ten years of the century：3Group work： Get Ss to discuss the following questions and ask them to present it before classQ1：What are the functions of the inventions?Q2：Are there any disadvantages of these inventions?
