Unit 2 Saving the Earth Topic 3 Section B（教學設計）
Ⅰ. Material analysis
本課主活動是1a。1a 通過Jane 告訴Michael怎樣才能成為一個環保人士來繼續學習提建議的表達方式，同時也向學生繼續傳遞更多的環保理念。1b是檢驗學生的聽力理解能力，1c 通過完成表格，來鞏固1a的內容。2要學生根據句意來進行詞語匹配和圖文匹配。3要學生根據上下文和首字母完成短文，這是對學生綜合能力的考查。短文不僅復習了已學的連接詞，還學習了新的連接詞：after all。4這個小組活動實際由兩部分組成：調查和匯報。 在做這個活動時，要求注意重讀、不完全爆破和連讀。目的在于糾正中國人學英語的薄弱環節：不能在交流中得體地運用重讀、不完全爆破和連讀。本課的各個環節都在傳遞環保理念。這對學生的環保意識的培養是非常有意義的。4這個活動要完整地體現，要比較長的時間，建議在課堂內完成語音語調部分即可。其它環節可在下次課的復習環節進行，還可以把其中的某些環節作為家庭作業。如：讓學生把自己的環保行為列成清單。這樣，下次課做調查時，就可以提高課堂效率。
