Who am I？教學(xué)設(shè)計(jì)一、教學(xué)對(duì)象分析本節(jié)課的教學(xué)對(duì)象為高一上學(xué)期的學(xué)生， 在經(jīng)歷了必修 1 的學(xué)習(xí)過(guò)程之后，學(xué)生已經(jīng)對(duì)高中的英語(yǔ)學(xué)習(xí)有了初步的了解和感知， 但仍需要訓(xùn)練和提高語(yǔ)篇的理解， 歸納和分析的能力。 本節(jié)課的一系列活動(dòng)， 就是為學(xué)生的語(yǔ)篇閱讀打開(kāi)一扇窗戶， 培養(yǎng)學(xué)生的語(yǔ)篇意識(shí)， 使其更全面的理解文章內(nèi)容，歸納主旨大意。學(xué)生在前一節(jié)課的詞匯學(xué)習(xí)中，已經(jīng)掌握了文中所出現(xiàn)的大部分生詞，這為本節(jié)課的閱讀掃清了障礙， 能讓學(xué)生更好的專注于語(yǔ)篇結(jié)構(gòu)的理解，而不必因?yàn)樯~過(guò)多影響閱讀效果。高一學(xué)生活潑好動(dòng)， 思維活躍，愿意積極的投入到思考和各種活動(dòng)中。這就需要老師積極熱情的引導(dǎo)，合理設(shè)計(jì)活動(dòng)環(huán)節(jié)， 有條理的分解知識(shí)層次， 幫助學(xué)生循序漸進(jìn)的掌握語(yǔ)篇的處理能力。二、教材內(nèi)容分析本節(jié)課閱讀材料是本單元的主要閱讀篇章， 屬科普類說(shuō)明文， 講述了計(jì)算機(jī)的發(fā)展歷史及其在當(dāng)今世界各個(gè)領(lǐng)域的應(yīng)用。 內(nèi)容較為抽象， 且有一些專業(yè)術(shù)語(yǔ)， 對(duì)高一學(xué)生來(lái)說(shuō)有一定的難度。 但寫作手法上以計(jì)算機(jī)為第一人稱進(jìn)行自白， 這種擬人的手法能夠激發(fā)學(xué)生的閱讀興趣， 也使得文章更淺顯易懂。本文共分 3 個(gè)段落，以時(shí)間為順序說(shuō)明計(jì)算機(jī)的發(fā)展歷史， 且每段的第一句話均為該段落的主題句。 這種結(jié)構(gòu)的語(yǔ)篇非常適合用來(lái)啟發(fā)和引導(dǎo)學(xué)生尋找段落的主題句， 并進(jìn)一步歸納文章主旨大意。 同時(shí)配以適當(dāng)?shù)木毩?xí)，幫助學(xué)生歸納總結(jié)出方法， 在練習(xí)中運(yùn)用這些方法， 從而提升對(duì)語(yǔ)篇的全局意識(shí)，增強(qiáng)對(duì)語(yǔ)篇的解題能力。Class Type:Reading classTeaching Aims:Knowledge aims:1. Students will be able to understand the new words and expressions from the text.2. Students can have a better understanding of the history and basic knowledge of computers.Ability aims:1. Students can talk about the passage after skimming, scanning and careful reading.2. Students can improve the abilities of reading and speaking. Emotional aims:1. Students can get more interests in learning English.2. Students will get great interest in learning computers and learn how to use computers correctly.Teaching Key Points:Have a clear picture of the development of computers in the order of time. Teaching Difficult Points:1. How to make students understand the terminology about computers?2. How to make students understand the passage and introduce the history and basic knowledge of computers?Teaching Aids: multi-media Teaching Procedures: Step 1 lead-inEnable students to guess the topic of this lesson.It is a machine, which you can use to type your homework, draw pictures, play games, watch movies, listen to music, communicate withyour friends, gather information Who am I? (Computer) 意 ： 學(xué)生通 英文描述，猜 所描述物品。而且以Who am I?的 引出。描述的內(nèi)容 并 近我 的生活，學(xué)生很容易猜出所描述的物品并能活 堂的氣氛， 下步 策略的教學(xué)做了有效的 。Step 2: Pre-readingShow some pictures of calculation tools such as abacus, calculator, huge computer, PC, laptop, PDA, and ask students to act as a guide, introducing them. Ask students to look at the pictures and the title of the reading passage. Predict what it is going to be about.設(shè)計(jì)意圖：讓學(xué)生通過(guò)介紹的方式，對(duì)電腦的發(fā)展史有個(gè)基本的了解，通過(guò)介紹計(jì)算機(jī)硬件可以擴(kuò)大學(xué)生的詞匯量，為理解文章做鋪墊， 同時(shí)激發(fā)了學(xué)生學(xué)習(xí)的興趣。Step 3: While-readingSkimming and scanning1. Ask students to skim the passage quickly to prove their guess and answer the questions.(1) Who am I? (A computer.)(2)What s the passage about? (It s about the history of computer.)(3)In which order is the text written? (According to the time.)2. Ask students to scan the text and find out the topic sentence of eachparagraph.設(shè)計(jì)意圖：在略讀和查讀過(guò)程中， 學(xué)生在對(duì)整個(gè)文章的大意有了基本的把握，鍛煉了學(xué)生快速閱讀的技巧。Careful reading1. Divide the students into two teams. Show some true or false questions on the screen.(1) Alan Turing built an Analytical Machine to solve any mathematical problems. (F)(2) People began to realize that the computer got cleverer and quicker with time passing. (T)(3) The computer began to serve the human race since it was brought into people s homes. (F)(4) Since the 1970s, the computer was used by people around the world through the Internet. (T)(5) The larger the computer is, the more memory it has. (F)Ask students to have a competition. They should stand up and decide whether it s true or false first and then find the information from the text to support their opinion.2. Ask students to work in groups of four people and complete the following chart. And then check the answers.(Suggested answers: calculating, analytical, cards with holes, universal machine, memory, laptop, the early 1960s, network, share, ways)3. Enable students to see the changes of computers shape, and come the inside of the computer. Then read paragraph 2 and fill in the blank.After that, present some pictures to help students understand the words easily.(Suggested answers: memory, in Tubes, On Transistors, On small chips, small)設(shè)計(jì)意圖：通過(guò)任務(wù)型教學(xué)法， 讓學(xué)生仔細(xì)閱讀文章， 可以加深學(xué)生對(duì)文章的理解。第二段的主要內(nèi)容是電腦內(nèi)部構(gòu)造的變化。難點(diǎn)是導(dǎo)管，晶體管和芯片的概念過(guò)于抽象， 通過(guò)圖片的展示和表格的填寫增強(qiáng)理解。Step 4: Post-reading1. Ask students to retell this passage with the help of the information that we have finished in while-reading.2. Have an interview: Imagine the students meet Bill Gates when going out of the museum. Invite a student to act as Bill Gates, the others may ask him the questions like these:(1) “ Mr.Bill Gates, could you tell us in what ways computers are used now?”(2) “ Mr. Bill Gates, what do you think the future computers will be like?設(shè)計(jì)意圖：根據(jù)已有信息復(fù)述文章可以加深學(xué)生對(duì)本課的掌握程度。設(shè)置采訪活動(dòng)，可以鍛煉學(xué)生用英語(yǔ)表達(dá)的能力，讓學(xué)生將所學(xué)的知識(shí)進(jìn)行信息輸出，加強(qiáng)說(shuō)的訓(xùn)練。在采訪的過(guò)程中，增強(qiáng)同學(xué)們的合作理念。Step 5: Discussion:Ask the students to discuss the advantages and the disadvantages.AdvantagesDisadvantages(1)communicate with friends(1)Some people especially the(2)listen to the musicteenagers are addicted to (癡迷） the(3)see films & watch newscomputer games and chatting on the(4)play gamesInternet. As a result，theyhave little(5)do shoppingtime to study.(6)save a lot of time(2)Some people use thecomputer(7)do a lot of useful thingswrongly.設(shè)計(jì)意圖：培養(yǎng)學(xué)生的語(yǔ)言知識(shí)的拓展和應(yīng)用能力，培養(yǎng)學(xué)生形成正確的電腦使用意識(shí)。Step 6:Homework:Write an article about the advantages and the disadvantages of thecomputer.設(shè)計(jì)意圖：培養(yǎng)學(xué)生的寫作技能，強(qiáng)化學(xué)生運(yùn)用語(yǔ)言知識(shí)能力。Blackboard Design:Teaching Reflection:
