Unit6 When was it invented Section B1a-1c
[學情分析]
九年級學生經過初中兩年的學習，已具有一定的英語綜合能力，也積累了一定的英語詞匯量，通過本單元前兩課時的學習對被動語態已基本知道如何正確表達。學生們對英語學習還保持著較濃厚的興趣，因此在教學中我應加強知識的強化并培養學生的學習興趣。同時，該年齡段的學生也很在乎他人的評價，所以在學習過程中我通過鼓勵性評價等措施，在教學活動中盡量讓他們參與到活動中來，創造更多的機會，鼓勵他們多說英語，樹立學好英語的自信心。通過學生間的合作學習，降低他們的學習難度，使他們體驗到成功的喜悅，從而提高學生的綜合語言應用能力。同時，通過此節課，也能了解到地方文化，自己家鄉的文化。 [教材分析]
本單元以“When was it invented ?”為話題展開教學活動，中心話題是the inventions,主要語言功能是用一般過去時的被動語態talk about the history of inventions.首先學會恰當地使用一般過去時的被動語態，再學會用被動語態描述各種發明。本部分為第六單元第三課時，是一節聽說課，主要學習幾個有關食物味道的形容詞，并通過聽說了解potato chips 的歷史。同時，利用當地特色文化—豆腐的發源故事進行拓展，讓學生能更好將英語運用到生活實際中。 [目標分析]

3.練習部分不是很多，少部分同學對被動語態把握的還不夠好。
其實我們生活中處處充滿可以利用的資源，關鍵是我們如何用心、用腦、用手去做。我國基礎教育課程改革的趨勢之一是加強課程與學生生活和現實社會的聯系。本次課程改革的內容強調聯系生活、社會、學生實際，在方法上強調探索、實踐、活動，實現課程生活化、社會化和實用化，但這并不是讓課程脫離學術軌道，而是讓課程和學生生活和現實社會更有效地融合起來，給已有充分發展的學術課程增添時代的源泉和生活的活力。我們有理由相信：怎樣有效的把課堂與生活緊密聯系在一起，化課堂為生活，融生活于課堂，是一個值得我們老師好好利用卻時時困擾我們的話題。只要我們做有心人，充分挖掘生活中的可利用資源。相信孩子們在學習中會獲得樂趣，在游戲中獲得知識，在課堂中除了學到語言，更多的是學會用語言的方法。真正使英語貼近生活，運用于生活，服務于生活。
