一、教學(xué)背景分析
(一)教學(xué)內容分析
本單元的中心話(huà)題是Food,主要語(yǔ)言功能項目是Talk about likes and dislikes,語(yǔ)法結構為Present tense to like, Yes / No questions and short answers, Affirmative and negative statements。本單元Section A所呈現的是與談?wù)撓埠门c厭惡相關(guān)的基本語(yǔ)言知識及其初步運用。這部分內容從呈現食物詞匯開(kāi)始,通過(guò)視、聽(tīng)等方式輸入信息,并引出本單元主要句型:Do you like…? 及其回答Yes,I do / No, I don’t.接著(zhù)設計了一個(gè)聽(tīng)力練習,要求圈出所聽(tīng)到的食物以及補全對話(huà),強化記憶所學(xué)詞匯和初學(xué)句型。然后教材設計了一個(gè)結對活動(dòng),以此操練主語(yǔ)是第三人稱(chēng)單數時(shí)句型的變化以及回答。并借此突出本單元的語(yǔ)法重點(diǎn)。最后教材設計的Food Survey起到了引導學(xué)生初步綜合運用所學(xué)語(yǔ)言的作用,以調查的形式使學(xué)生在富有挑戰性的活動(dòng)中主動(dòng)運用所學(xué)語(yǔ)言,落實(shí)新知。Section B是在Section A基礎上的知識的擴展和延伸。本單元中,Section B首先以聽(tīng)、說(shuō)、寫(xiě)的形式展開(kāi)了食物與名稱(chēng)配對以及對食物進(jìn)行分類(lèi)。接著(zhù)設計了聽(tīng)力填寫(xiě)Sandra和Tom喜歡與不喜歡的食物;自然引到了談?wù)撘蝗杖偷脑?huà)題的結對活動(dòng),實(shí)現了新舊知識的綜合運用;一日三餐合理健康膳食引出同步閱讀;之后的寫(xiě)一段話(huà)談?wù)凾om 的一日三餐到寫(xiě)一段關(guān)于自己一日三餐喜歡吃的食物,直到最后的小組活動(dòng)列出購物清單,使學(xué)生從完成半真實(shí)的任務(wù)轉向了完成真實(shí)的任務(wù),從而達到了創(chuàng )造性活用所學(xué)語(yǔ)言的目的。Self check部分的主要內容是對本單元主要詞匯及語(yǔ)言運用能力的自我評價(jià)。
綜上所述,本單元以食物為主線(xiàn),圍繞著(zhù)談?wù)撓矚g與不喜歡以及一日三餐等語(yǔ)言功能項目展開(kāi)了一系列任務(wù)活動(dòng)。教材內容從基本語(yǔ)言知識到語(yǔ)言綜合運用層層遞進(jìn),聽(tīng)說(shuō)讀寫(xiě)依次展開(kāi),以一種循序漸進(jìn)的生活化的學(xué)習程序,引導學(xué)生在做事中有目的地學(xué)習語(yǔ)言。
