2）Students will be able to have a thorough understanding of the title.
教學準備：多媒體；黑板
教學過程：
Step1 課前準備
Before the class, a short video will be played. Actually, it is a part from the Lion King. 設計意圖：為在課堂上導入computer的話題做準備，同時為學生創造一個輕松的課堂氛圍。
Step2: Pre-reading
1)Ask students to talk about their opinion of the cartoon character Simba, which will
naturally lead to today’s topic---computer.
2) Students will be asked to speak about the computer’s daily functions. 設計意圖：通過對獅子王主人公辛巴的探討，自然的把從卡通人物引到本課的主題電腦；電腦是學生非常熟悉的物品，要求學生對其日常的功能進行探討，并交代詞匯function對下面的活動進行鋪墊。
3）Ask students to predict who I am in the passage?
設計意圖：對完成整篇閱讀后重新回到此問題進行鋪墊。
Step3 Fasting reading
1)Ask Ss to read the passage very quickly and find out the main idea of each paragraph.
2) Emphasize the skill of finding the main idea
3)Based on the main idea of each paragraph, students will be asked to
summarize the main idea of the whole passage.

1822, 1936 and since the 1970s. Ss will be asked to point out the name of the computer at that time as well as its function.
2) Ss will be asked to think about why computers became smarter even if the size of it became smaller
設計意圖：學生通過對這4個時間段的查找能自然的了解計算機的發展史，搞清楚在各個時間段它的另外一個身份及功能，這也是本堂課的重點。在這過程中能培養學生scanning能力，理解并掌握單詞functions, calculate, simplify, analytical, solve some mathematical problems，technological revolution artificial intelligence Para2& Para3: 1) Read these two paragraphs carefully and answer the questions
How did these changes become possible?
What new applications have been found for me?
Big challenge: Find out three different feelings mentioned in
para2 & para3
2)Ask Ss to answer why the computer became happy.
設計意圖：學生通過此環節可以了解計算機尺寸變小但腦力變強的原因及電腦在當今社會的應用；得出第二段及第三段計算機的另外身份也是本課的重難點所在，為總結全文及更好的回答who am I 做準備；聯系人類實際要互相合作及幫助才能生活的開心。在這過程中能培養學生scanning能力，理解并掌握單詞network，applications。
Step5： Summary of the passage
Ask Ss to answer the question “ who am I ” again.
設計意圖：對于這篇內容進行總結，更好的理解計算機的多重身份，并為下一環節做鋪墊。
Step 6 Post reading：
Introduce the new kind of computer iPad created by Steve Jobs’ Apple Corporation and then ask Ss to design a new kind of computer
設計意圖: 激發學生的創造力和想象力，培養學生的合作能力及口頭表達的能力
Step7：Summary and Homework
