III．教材分析与教材重组
1.教材分析
本单元以机器人和科幻小说为话题，介绍了20世纪世界知名的科幻小说家IsaacAsimov写于1951的SatisfactionGuaranteed和作者的生平。
通过本单元的教学，旨在让学生了解科幻小说最大的特征在于，它赋予了“幻想”依靠科技在未来得以实现的极大可能，甚至有些“科学幻想”在多年以后，的确在科学上成为了现实。
如IsaacAsimov1951年描述的机器人的部分功能已经被应用于现实生活和工作中。
在教学中，要鼓励学生敢于幻想，大胆创新，发挥自己丰富的想象力和创作力，写出独具特色的科幻文章。
1.1WARMINGUP介绍了什么是机器人，和不同种类及不同形状的机器人。
1.2PRE-READING通过讨论机器人是否像人类一样有自己的思维，是否有感情引出IsaacAsimov的科幻小说SatisfactionGuaranteed。
为本单元的READING做好了铺垫。
1.3READING课文是IsaacAsimov写于1951的科幻小说SatisfactionGuaranteed。
文中描述的机器人Tony是一个除去面无表情外，身材高大，相貌英俊，聪明机智的完美男人。
仅三周的时间就使女主人坠入爱河。
1.4COMPREHENDING共有2部分，第一部分是关于课文内容的5个问答题，旨在考察学生对课文的理解。
第二部分要求学生比较机器人Tony在physical,mental,emotional三方面与人的异同。
与PRE-READING部分的问题相呼应。
1.5LEARNINGABOUTLANGUAGE分为两部分，Discoveringusefulwordsandexpressions是本单元词汇练习题；Discoveringusefulstructures是本单元语法练习题，通过本单元的学习，要求学生熟练掌握不定式的被动语态。
1.6USINGLANGUAGE分为两部分，Listening,discussingandwriting部分内容是Molly和Kate讨论SatisfactionGuaranteed的对话录音，要求学生根据对话内容学会运用表达自己观点的常用句型。
这部分教学内容还要求学生以机器人为话题，充分发挥自己的想象力，谈论机器人做家务的利与弊。
并且要求自己动手设计机器人，附上文字说明。
Readinganddiscussing部分的内容是科幻小说家IsaacAsimov的生平介绍。
文章后附有练习题。
第一题要求学生根据时间线，了解在作者生命中发生的重要事件。
第二、三题要求学生讨论IsaacAsimov的“机器人三定律”。
2.教材重组
2.1将WARMINGUP、PRE-READINGR、READING与COMPREHENDING放在一起上一节阅读课。
2.2把LEARNINGABOUTLANGUAGE和WORKBOOK的Usingwordsandexpressions及Usingstructures整合在一起上一节词汇语法。

2.4将WORKBOOK的Listening和Readingtask设计为一节阅读课写作课。
