英語(yǔ)必修2 Unit 3中閱讀部分Who am I?的說(shuō)課稿一 教材分析1 閱讀教學(xué)歷來(lái)是高中英語(yǔ)教學(xué)的重頭戲，閱讀教學(xué)肩負(fù)著對(duì)學(xué)生閱讀技巧和方法培養(yǎng)的重任。Who am I?這篇文章以第一人稱的手發(fā)介紹了計(jì)算機(jī)發(fā)展演變的歷史和計(jì)算機(jī)在各個(gè)領(lǐng)域的應(yīng)用，其主旨是表達(dá)計(jì)算機(jī)的發(fā)展變化之快以及在生活中的用途之廣。2 教學(xué)目標(biāo)語(yǔ)言目標(biāo)單詞和短語(yǔ) ：simplify;sum;operator;logically;solve;reality;personal;tubes;totally;network;application;finance;mobile;rocket;explore;anyhow;goals;happiness; Technological revolution;artifical intelligence;from then on;as a result; 重點(diǎn)句子:Although I was young I could simplify difficult sums.I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage.As time went by,I was made smaller.能力目標(biāo)a.通過(guò)預(yù)測(cè)及找每段的主題句，提高（fast-reading）的能力，掌握大意。b.通過(guò)列出計(jì)算機(jī)發(fā)展演變的幾個(gè)階段，提高（carefull-reading）的能力。c.通過(guò)找文章的的主題句和支持論據(jù)，培養(yǎng)篇章分析和總結(jié)概括能力。情感目標(biāo)感受計(jì)算機(jī)發(fā)展變化之快，明白網(wǎng)上交友的好與壞，學(xué)會(huì)合理運(yùn)用網(wǎng)絡(luò)資源。3 教學(xué)的重難點(diǎn)：重點(diǎn)：掌握文章的脈絡(luò)，大意及相關(guān)細(xì)節(jié)信息；理解文章的結(jié)構(gòu)，豎立合理運(yùn)用網(wǎng)絡(luò)資源的意識(shí)。難點(diǎn)：理解文章的篇章結(jié)構(gòu)；二 學(xué)生情況分析 本班41個(gè)學(xué)生，其中三分之二都是男生。他們對(duì)于英語(yǔ)學(xué)習(xí)的積極性和參與英語(yǔ)課堂的主動(dòng)性不高。對(duì)于信息容量大的閱讀課，多數(shù)學(xué)生都有一種懼怕心里。不過(guò)對(duì)于IT這個(gè)和現(xiàn)實(shí)生活聯(lián)系很強(qiáng)的中心話題，學(xué)生很感興趣。因此，我閱讀課的閱讀設(shè)計(jì)都本著能調(diào)動(dòng)大多數(shù)學(xué)生的積極參與為原則。三 教材處理讓學(xué)生看課本上的圖片，主要是提起學(xué)生課堂參與的積極性。讓學(xué)生先讀和記文章中黑體的單詞并快速寫下中文意思。把學(xué)生分成小組，讓他們相互幫助完成相關(guān)的閱讀任務(wù)。讓學(xué)生帶著相關(guān)的閱讀任務(wù)去讀文章。播放課本錄音，讓學(xué)生邊聽(tīng)邊檢查自己的答案。師生互動(dòng)核對(duì)答案。 四教法分析依據(jù)新課程標(biāo)準(zhǔn)的理念要求，結(jié)合本班的實(shí)際，為達(dá)成上述的教學(xué)目標(biāo)；本著以學(xué)生為主的原則，我主要才用了任務(wù)型教學(xué)法，整提教學(xué)法和交際法。五教學(xué)過(guò)程Step1. lead-in ( pre-reading ) 1+5minutes Ask students to look at the picture on page17and the title of the reading passage.
