Ⅲ. 教材分析和教材重組
1. 教材分析
本單元以Inventors and inventions為話題，旨在通過單元教學，使學生了解發明和發現的區別，了解發明創造的過程和獲得專利的條件，學習發明家的成功事例；能靈活運用基礎句型描述中外古代和現代發明，談論不同發明的優缺點及其現實意義；根據不同問題及條件設計、改進發明并闡述自己的觀點；能寫一封有創新的求職申請，闡述自己的特長和優勢，能對別人的發明、創造或觀點提出意見或建議；并能運用所學知識利用現實生活中有限材料進行發明創造。
1.1 Warming Up 提供了三幅不同發明或發現的圖片，讓學生運用已有的知識和經驗，區分發明和發現的不同含義；并能與同伴合作描述現代發明在現實生活中的作用。
1.2 Pre-reading要求學生將課本所列關于進行科學研究或發明創造所必須經歷的幾個階段（步驟或過程）進行正確的排序。了解每一項發明在得到社會承認前都必須經歷一個過程。
1.3 Reading是一篇記敘性的文章。作者在文中詳細介紹了從發現問題（snake trouble）、分析問題（products that might help）到解決問題（remove the snakes）的全過程，并介紹了專利申請方面的一些知識。
1.4 Comprehending第一個訓練題要求學生根據課文內容回答問題；第三個訓練題要求學生運用科學步驟設計一項發明解決課本所提供的三個問題，并與同學交流觀點。
1.5 Learning about Language分兩部分。第一部分要求學生利用填空、改寫句子的方式復習所學詞匯及表達法。第二部分重點練習過去分詞作定語的用法。
1.6 Using Language分成四部分。第一部分Reading要求學生閱讀一篇介紹發明家Alexander Graham Bell的文章并回答有關問題，了解電話發明者貝爾的發明及其成功的原因。第二部分Listening and speaking 是一段關于Zhou Rui對一家發明公司的工程師進行電話采訪的聽力材料。要求學生掌握電話交談常用表達；并在此基礎上進行角色扮演活動，即求職者與公司考核人員之間的電話交談。第三部分Writing要求學生寫一封求職信，列舉自己的優勢、特長和工作經歷向這家發明公司提出求職申請。
2． 教材重組
2.1 從話題內容及訓練目的分析，Warming Up與Speaking和Workbook中的TALKING相一致，可將這三部分整合在一起，設計成一節任務型“口語課”。
2.2 將Listening and speaking和Workbook中的LISTENING, LISTENING TASK整合在一起，設計成一節“聽力課”。
2.3 可將Pre-reading, Reading和Comprehending三個活動整合在一起上一節“閱讀課（一）”。

2.5 可將Using Language中Reading和Workbook中READING TASK整合起來，上一節“閱讀課（二）”。
2.6 將Using Language中的Writing和Workbook中的WRITING TASK整合為一節“寫作課”。
