1．8 Checkpoint 2是本單元語言知識(shí)的反饋和強(qiáng)化。分為謂語形式和單元話題詞匯與句式復(fù)習(xí)兩個(gè)部分，此項(xiàng)內(nèi)容可以作為反饋練習(xí)來強(qiáng)化單元知識(shí)。
1．5 LANGUAGE STUDY 分詞匯和語法兩部分。其中，Word study的前兩個(gè)練習(xí)序列性很強(qiáng)，兩個(gè)練習(xí)設(shè)計(jì)注重詞性拓展和運(yùn)用。任務(wù)中基本涉及到本單元重點(diǎn)詞匯和常見詞匯，但是對(duì)學(xué)生而言，僅依靠這樣兩個(gè)任務(wù)設(shè)計(jì)是不能夠達(dá)到熟練的目的，因此應(yīng)該適當(dāng)?shù)脑贖omework或者Integrating Skills部分運(yùn)用恰當(dāng)?shù)娜蝿?wù)設(shè)計(jì)來達(dá)到使學(xué)生能夠熟練運(yùn)用這些詞匯的目標(biāo)。Word Study的第三個(gè)練習(xí)訓(xùn)練學(xué)生在語境中運(yùn)用詞匯的能力，材料內(nèi)容補(bǔ)充了本單元話題的背景知識(shí)。Word Study基本上呈現(xiàn)出了本單元的重點(diǎn)詞匯，任務(wù)形式以訓(xùn)練為載體，強(qiáng)調(diào)了語言知識(shí)的運(yùn)用能力，因此教學(xué)中要細(xì)處理。Grammar 則分成兩個(gè)Parts. Part 1要求學(xué)生要學(xué)會(huì)識(shí)別和判斷Predicate；Part2強(qiáng)調(diào)了Predicate在語篇中的運(yùn)用。由于是復(fù)習(xí)內(nèi)容，所以兩個(gè)Task的內(nèi)容設(shè)計(jì)顯得簡(jiǎn)單，可以適當(dāng)補(bǔ)充一些Tasks來強(qiáng)化學(xué)生在寫作過程中準(zhǔn)確運(yùn)用Predicate的能力。
1．4 READING部分包括Pre-reading, Reading 和Post-reading三個(gè)部分。 Pre-reading以Silk Road為主題，輸入背景知識(shí)，促進(jìn)學(xué)生對(duì)Reading的深刻理解。Reading講述了海上絲綢之路開辟的背景、發(fā)展和繁榮，文章的后半部分重點(diǎn)記敘了鄭和下西洋的過程和意義。Reading的主題內(nèi)容明確，此主題是培養(yǎng)學(xué)生民族自豪感的好材料。Reading的語言材料不難，但是由于文章所記敘的內(nèi)容時(shí)間跨度很大，關(guān)系略顯復(fù)雜，學(xué)生不易把握文章的結(jié)構(gòu)。教學(xué)中處理好背景知識(shí)輸入和讀懂文章整體結(jié)構(gòu)的任務(wù)設(shè)計(jì)，就基本可以很好地完成教學(xué)任務(wù)。Post-reading是對(duì)Reading內(nèi)容的熟練和主題的拓展，最后一個(gè)任務(wù)升華了主題。這些任務(wù)設(shè)計(jì)都要求學(xué)生跨越段落尋找信息，因此教學(xué)設(shè)計(jì)中要適當(dāng)補(bǔ)充和重新設(shè)計(jì)Tasks，以使得大多數(shù)學(xué)生都能讀透文章。
1．3 SPEAKING 部分包括三個(gè)Situations。三個(gè)Situations都是以科學(xué)發(fā)現(xiàn)和探測(cè)為主題，提出問題情境，旨在培養(yǎng)學(xué)生對(duì)問題情境的判斷能力和運(yùn)用語言解決問題的能力。問題的情境設(shè)計(jì)具有思辨性特征，學(xué)習(xí)者只有對(duì)問題情境的深刻理解，才能做出準(zhǔn)確的判斷，在此基礎(chǔ)上形成決策。
1．2 LISTENING包括Pre-listening, While-listening和Post-listening三個(gè)部分。Pre-listening的目的是培養(yǎng)學(xué)生聽前預(yù)測(cè)的能力，這就使得聽的過程目的性很強(qiáng)。Post-listening的兩個(gè)任務(wù)設(shè)計(jì)各有側(cè)重，任務(wù)1強(qiáng)調(diào)對(duì)聽力內(nèi)容的整體理解，任務(wù)2則側(cè)重對(duì)話題思想的理解，重在培養(yǎng)學(xué)生解決問題的能力。整體上來看，Listening的設(shè)計(jì)旨在培養(yǎng)學(xué)生預(yù)測(cè)、選擇、判斷和深層加工信息的能力。
1．1 WARMING UP 以4位中外航海家的圖片為引線，引出了本單元人物和話題。4個(gè)任務(wù)設(shè)計(jì)層層深入，首先由人物事跡逐漸導(dǎo)向單元話題——Exploration。最后一個(gè)任務(wù)把話題引向具體的單元話題的目標(biāo)語言。
1． 教材分析
本單元的話題是Crossing limits，話題涉及的歷史和地理知識(shí)龐雜，給學(xué)生理解文章帶來了較大難度。Pre-reading, Reading和Post-reading部分涉及了許多背景知識(shí)，這會(huì)給學(xué)生精讀文章帶來障礙。Warming Up, Listening和Integrating Skills部分涉及到Exploration話題的空間跨度很大，因此解決好中外、過去和現(xiàn)在Exploration的關(guān)系可以促進(jìn)學(xué)生理解話題——跨越極限。Speaking和Writing以判斷和勸誘為主題，旨在通過理解和學(xué)習(xí)話題，發(fā)展學(xué)生理解觀點(diǎn)和形成自主判斷，促進(jìn)學(xué)生的自主決策能力。
