四上 Unit4 Seasons Lesson3 Little Leaf 教學設計
一、教材分析：
本文與魯科版英語教材四年級上冊第四單元 Seasons 相匹配，本單元的四個語篇從不同角度談論季節，單元內各語篇與單元主題之間，以及各語篇之間相互關聯，構成四個子主題，即“認識四季”“感受四季”“熱愛四季”“感悟四季”。
本節繪本故事是在課文的基礎上的擴展和延伸，主要講述了小樹葉在四季的經歷:在春日中伸展，在春風中舞蹈，在春雨中淋浴，在夏日中成長并為人類奉獻樹蔭，在秋日著霜并變換顏色，在冬日離開大樹，化作春泥滋養大樹，來年大樹長出新的樹葉，生命在四季變換
中輪回。學生通過閱讀繪本故事，了解如何描述小樹葉在四季的經歷，感受生命在四季輪回中成長并充滿希望，激發學生享受四季生活、尊重生命、熱愛自然、保護自然的情感。同時引導學生感悟隨著季節的推移，小樹葉和好朋友們的心情變化，體會小樹葉的偉大，進而迸發出熱愛自然，保護自然生態的美好情感。
該繪本為配圖故事，通過精美的插圖和簡潔明快的文字相結合，按照季節順序呈現為四個部分，采用一般現在時，對小樹葉在四個季節的活動進行了描述，語言簡潔、生動、富有韻律感，凸顯出繪本的主題意義。
二、學情分析：
四年級學生年齡在十歲左右，生性活潑好動，喜歡直觀形象，愛唱、愛跳、愛玩、善于模仿，敢于開口。通過兩個學期的學習，他們已經掌握了一些常用的問候語和對話，有了一定的詞匯量，能聽懂簡單的課堂用語，能根據老師的指揮做出適當的回應。但是，他們的注意力時間仍然比較短。所以設計課堂活動的時候要有一定的思考性、趣味性，能帶給他們一定的新鮮感，才能吸引他們的興趣，才能使每個學生參與到課堂學習活動中。因此，在教學設計時，我面向全體學生，以學生的發展為宗旨，始終把激發學生的學習興趣放在首位。同時，多給他們說的機會，提高他們的口語水平，提升他們的語用能力。
三、教學目標：
通過本課時的學習，學生能夠:
1.在看、聽、讀、演的活動中，了解故事的發展，提取故事的核
心信息，總結故事的主要內容，獲取、梳理小樹葉四季的變化，感知
和理解故事內容。(學習理解)
2.在圖片、板書和語言支架的幫助下，復述故事主要情節，感受
小樹葉的偉大。(應用實踐)
3.通過讀圖、觀看視頻等方式，在教師的幫助下總結保護地球自
然生態的舉措，結合生活實際，完成給地球的回信并報告。(遷移創
新)
四、教學重難點：
引導學生深入理解《Little Leaf》繪本的內容，體會小葉子從生長到凋落的生命歷程，以及它所傳遞的關于成長、變化和生命意義的深刻寓意，樹立熱愛自然、保護自然生態的意識。
