Ⅲ.教材分析和教材重组

1.教材分析

本单元主要话题是Howtoorganizescientificresearch。

旨在通过本单元的教学培养学生探究科学、崇尚科学的精神和正确的科学观；

帮助学生了解科学的本质和科学家的特质，使学生懂得科学探究的基本步骤和要素；

指导学生如何对科学家及其所从事的科研工作进行描述、发表看法，并针对自己的个性特征和兴趣专长，畅谈个人的职业志向和人生规划。

1.1WarmingUp通过问答形式使学生回顾不同领域不同时代的10位科学家，了解他们对人类的贡献及其成果。

1.2Pre-reading通过对几个问题的讨论，使学生了解传染病和“霍乱”的基本常识，并了解科研过程中验证某些观点的基本程序和方法。

1.3Reading介绍英国著名医生JohnSnow是如何通过考察分析、探究的科学方法，发现并控制“霍乱”这种传染病的。

通过课文学习，使学生了解科学发现的全过程及其严密性；

学习描述性文体的基本写作框架。

1.4Comprehending共设计了四个题型。

1.5LearningaboutLanguage共设计了两大部分，8个练习，对本单元的重点词汇和主要语法项目进行训练。

第一部分的1-4题旨在训练学生对重点词汇、短语的运用；

第二部分旨在练习过去分词作定语和表语的用法。

1.6UsingLanguage由两部分组成：

Listeningandspeaking是一段关于中国著名科学家钱学森先生的生平介绍的听力材料；

Readingandwriting是一段关于伟大天文学家哥白尼发表“日心说”过程的短文。

2．教材重组

2.1将WarmingUp，Pre-reading,Reading和Comprehending三部分整合为一节“精读课”。

2.2将UsingLanguage中的Copernicus’RevolutionaryTheory和Workbook中的FINDINGTHESOLUTION整合为一节“泛读课”。

2.3将LearningaboutLanguage中的Discoveringusefulstructures和Discoveringusefulwordsandexpressions以及Workbook中的USINGSTRUCTURES和USINGWORDSANDEXPRES-SIONS整合为一节“语言学习课”。

2.4将UsingLanguage中的Listening与Workbook中LISTENING和LISTENINGTASK三个部分整合为一节“听力课”。

2.5将UsingLanguage中的Speaking与Workbook中的TALKING和SPEAKINGTASK三个部分整合为一节“口语课”。

2.6将UsingLanguage中的ReadingandWriting以及Workbook中的WRITINGTASK整合为一节“写作课”。
