第四課時課時內(nèi)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(xué)習(xí)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(dá)。讓學(xué)生了解中西方鞋子尺碼的不同，培養(yǎng)學(xué)生學(xué)習(xí)英語的興趣以及樹立學(xué)好英語的信心。第三課時中已經(jīng)學(xué)習(xí)了How heavy are you? Im. kilograms.的表達(dá)，為本課時奠定了基礎(chǔ)。I wear 的句型四年級也已經(jīng)學(xué)過，學(xué)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(xué)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(dá)。本課時包括Lets try和Lets talk兩個板塊。Lets try通過聊天呈現(xiàn)了Lets talk 的背景。學(xué)生通過聽力練習(xí)獲得Lets talk板塊的人物和場景信息，為進(jìn)入Lets talk的學(xué)習(xí)做好了準(zhǔn)備。Lets talk 板塊通過吳一凡和Mike 在鞋店試穿鞋子的情景，讓學(xué)生感知What size are your shoes? Size.How heavy are you? Im. kilograms.的語義和語用情景，學(xué)會如何在這樣的情景下表達(dá)。此情境是發(fā)生在鞋店里，與學(xué)生的生活息息相關(guān)，很能激起學(xué)生的求知欲。本課題涉及了前面幾個課時的內(nèi)容，在設(shè)計本課教學(xué)過程時，我采用游戲、問答的方法，幫助學(xué)生鞏固學(xué)過的知識。學(xué)習(xí)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(fā)揮學(xué)生的主體作用。課時目標(biāo)1. 能夠理解對話大意。2. 能夠用正確的語音、語調(diào)朗讀對話，并能進(jìn)行角色扮演。3. 能夠聽、說、讀、寫句型：What size are your shoes?
