第四課時課時內容B Lets try Lets talk課時分析本課時是人教版六年級下冊第一單元第四課時，與第三課時緊密相連。圍繞“穿多大號的鞋”這一話題展開，主要通過對話學習句型What size are your shoes? I wear size .shoes./ Size.My shoes are size.及鞏固句型How heavy are you? Im. kilograms.的表達。讓學生了解中西方鞋子尺碼的不同，培養學生學習英語的興趣以及樹立學好英語的信心。第三課時中已經學習了How heavy are you? Im. kilograms.的表達，為本課時奠定了基礎。I wear 的句型四年級也已經學過，學生對于穿多大號的鞋的回答很容易掌握。所以本課時的重點是幫助學生理解和運用詢問對方穿多大號的鞋及它的幾種回答的表達。本課時包括Lets try和Lets talk兩個板塊。Lets try通過聊天呈現了Lets talk 的背景。學生通過聽力練習獲得Lets talk板塊的人物和場景信息，為進入Lets talk的學習做好了準備。Lets talk 板塊通過吳一凡和Mike 在鞋店試穿鞋子的情景，讓學生感知What size are your shoes? Size.How heavy are you? Im. kilograms.的語義和語用情景，學會如何在這樣的情景下表達。此情境是發生在鞋店里，與學生的生活息息相關，很能激起學生的求知欲。本課題涉及了前面幾個課時的內容，在設計本課教學過程時，我采用游戲、問答的方法，幫助學生鞏固學過的知識。學習對話時采用整體感知對話、局部處理語言、模仿對話、表演對話的方法，充分發揮學生的主體作用。課時目標1. 能夠理解對話大意。2. 能夠用正確的語音、語調朗讀對話，并能進行角色扮演。3. 能夠聽、說、讀、寫句型：What size are your shoes?
