英語必修2 Unit 3中閱讀部分Who am I?的說課稿一 教材分析1 閱讀教學歷來是高中英語教學的重頭戲，閱讀教學肩負著對學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)介紹了計算機發(fā)展演變的歷史和計算機在各個領(lǐng)域的應(yīng)用，其主旨是表達計算機的發(fā)展變化之快以及在生活中的用途之廣。2 教學目標語言目標單詞和短語 ：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a.通過預(yù)測及找每段的主題句，提高（fast-reading）的能力，掌握大意。b.通過列出計算機發(fā)展演變的幾個階段，提高（carefull-reading）的能力。c.通過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。情感目標感受計算機發(fā)展變化之快，明白網(wǎng)上交友的好與壞，學會合理運用網(wǎng)絡(luò)資源。3 教學的重難點：重點：掌握文章的脈絡(luò)，大意及相關(guān)細節(jié)信息；理解文章的結(jié)構(gòu)，豎立合理運用網(wǎng)絡(luò)資源的意識。難點：理解文章的篇章結(jié)構(gòu)；二 學生情況分析 本班41個學生，其中三分之二都是男生。他們對于英語學習的積極性和參與英語課堂的主動性不高。對于信息容量大的閱讀課，多數(shù)學生都有一種懼怕心里。不過對于IT這個和現(xiàn)實生活聯(lián)系很強的中心話題，學生很感興趣。因此，我閱讀課的閱讀設(shè)計都本著能調(diào)動大多數(shù)學生的積極參與為原則。三 教材處理讓學生看課本上的圖片，主要是提起學生課堂參與的積極性。讓學生先讀和記文章中黑體的單詞并快速寫下中文意思。把學生分成小組，讓他們相互幫助完成相關(guān)的閱讀任務(wù)。讓學生帶著相關(guān)的閱讀任務(wù)去讀文章。播放課本錄音，讓學生邊聽邊檢查自己的答案。師生互動核對答案。 四教法分析依據(jù)新課程標準的理念要求，結(jié)合本班的實際，為達成上述的教學目標；本著以學生為主的原則，我主要才用了任務(wù)型教學法，整提教學法和交際法。五教學過程Step1. lead-in ( pre-reading ) 1+5minutes Ask students to look at the picture on page17and the title of the reading passage.
