How Do You Use the Internet教學(xué)設(shè)計章節(jié)名稱八年級下Unit 4 lesson19學(xué)時1教材分析本課是冀教版英語八年級下冊第四單元第一課時How Do You Use the Internet，教材以使用計算機(jī)上網(wǎng)為話題,從學(xué)生熟悉的日常活動出發(fā)來探討計算機(jī)與網(wǎng)絡(luò)的功能，認(rèn)識網(wǎng)絡(luò)對我們學(xué)習(xí)和生活的積極作用和消極影響,鼓勵學(xué)生利用網(wǎng)絡(luò)了解世界探索未知,要求學(xué)生學(xué)會科學(xué)合理安全地上網(wǎng)。通過解讀課文對話和設(shè)置針對性練習(xí)來學(xué)習(xí)if引導(dǎo)的條件狀語從句，熟練掌握一般現(xiàn)在時和一般將來時的運(yùn)用，正確使用情態(tài)動詞can和must。課文由“想一想”、“主題對話”和“一起做”三部分組成。在“想一想”這一部分，預(yù)設(shè)的兩個問題引出了本課的主要內(nèi)容和兩個關(guān)鍵詞“computer”，“internet”,為課文學(xué)習(xí)做了有效鋪墊；“主題對話”則重點(diǎn)圍繞使用電腦上網(wǎng)能干些什么展開討論和設(shè)想，相關(guān)的詞匯、短語、句型次第呈現(xiàn)，尤其以“if”引導(dǎo)的條件狀語從句反復(fù)出現(xiàn)，成為本課學(xué)習(xí)的重點(diǎn)和難點(diǎn)。在“一起做”這一部分，分別設(shè)置了“快速閱讀找信息”、“用動詞正確形式填空”以及“綜合實踐運(yùn)用“三道練習(xí)，既注重知識鞏固，又著眼能力培養(yǎng)。本課時是一般將來時態(tài)和一般現(xiàn)在時態(tài)的綜合運(yùn)用，為正確運(yùn)用這兩種時態(tài)提供場景，也為條件狀語復(fù)合句的學(xué)習(xí)奠定基礎(chǔ)，具有承前啟后的作用；就整個單元來說它既是本單元的基本語言內(nèi)容，又為本單元的知識擴(kuò)展和語言綜合運(yùn)用奠定基礎(chǔ)。 學(xué)情分析八年級學(xué)生已經(jīng)學(xué)過一般將來時態(tài)和一般現(xiàn)在時態(tài)，已了解了這兩種時態(tài)的肯定句、否定句、一般疑問句等形式。首次接觸if引導(dǎo)的條件狀語從句，在接受上會有一些難度，這就要求教師在引入的時候要多從學(xué)生的角度思考。在口語運(yùn)用中判斷if條件句的主句、從句也許會存在一定的困難。在運(yùn)用一般將來時和一般現(xiàn)在時態(tài)也許會產(chǎn)生混淆。教學(xué)目標(biāo)一、知識目標(biāo)1.Words and expressions in this lesson .2.Target language :I used to have a desktop computer.How does the Inteernet help you?If you work hard , youll complete your research. .3.掌握一般現(xiàn)在時和一般將來時兩種時態(tài)的運(yùn)用。4.學(xué)習(xí)用if引導(dǎo)的條件狀語從句:。二、語言技能目標(biāo)（1）能用if引導(dǎo)的條件狀語從句來作出假設(shè)，用will來談?wù)摻Y(jié)果，如：If you do, youll be late.（2）能用“I think Im going to”來表達(dá)作出的決定，如：I think Im going to the party with Karen and Ann.語言知識目標(biāo)（1）正確運(yùn)用if引導(dǎo)的條件狀語從句，如：If you do, you will have a great time.（2）運(yùn)用what對if引導(dǎo)的句子所產(chǎn)生的結(jié)果進(jìn)行提問，如：What will you do if you have a computer?三、情感態(tài)度目標(biāo)（1）激發(fā)學(xué)生對科學(xué)的熱愛和對英語學(xué)習(xí)的興趣；（2）認(rèn)識網(wǎng)絡(luò)對我們學(xué)習(xí)和生活的積極作用和消極影響，引導(dǎo)學(xué)生科學(xué)合理安全地上網(wǎng)。教學(xué)重難點(diǎn) 重點(diǎn)：（1）鞏固和運(yùn)用運(yùn)用一般現(xiàn)在時和一般將來時。（2）學(xué)習(xí)if引導(dǎo)的條件狀語從句。難點(diǎn)： 條件狀語從句中主句和從句的判斷及時態(tài)的運(yùn)用。 教學(xué)方法創(chuàng)設(shè)情境法、口語交際法、Pairwork。 通過創(chuàng)設(shè)開放式教學(xué)情境，兩人一組合作交流，使學(xué)生在具體的語言環(huán)境中感受if 條件狀語從句的用法。信息技術(shù)應(yīng)用錄音，多媒體課件教學(xué)過程教學(xué)內(nèi)容教學(xué)活動設(shè)計意圖Step 1: Leading-inGreet the class.Introduce the new unit.T: Today we will begin a new unit with its title“The Internet Connect Us.What is the Internet. do you know?S:Yes,The Internet is 因特網(wǎng) in Chinese.T: Right.What does“connect”mean？S：連結(jié)。In English it means“put together”.
