1、Lesson 1 What Is a Computer?、教學(xué)目標(biāo)1 .了解計(jì)算機(jī)的基礎(chǔ)知識(shí)2 .熟記單詞3 .閱讀課外文章二、課時(shí)分配4 項(xiàng)目共2個(gè)任務(wù)，安排3課時(shí)。三、教學(xué)重點(diǎn)計(jì)算機(jī)已成為人們生活和工作中不可或缺的一部分。本項(xiàng)目主要介紹電腦的 相關(guān)信息。熟記相關(guān)重點(diǎn)單詞，與英語(yǔ)語(yǔ)法。四、教學(xué)難點(diǎn)1 .熟悉單詞中文意思。2 .拓展課外閱讀3 .熟悉相關(guān)語(yǔ)法。五、教學(xué)內(nèi)容Since the technology is developing rapidly nowadays, nearly all people are familiar with computers. It has become

2、 an essential part of human life. Everyone is keen on it. Now let' s see what a computer is.It can store and process data and produce output results under the direction of a stored program of instructions in a very fast and accurate way. It can not only deal with letters, characters and figures

3、but also sounds, images and information of other sorts. It is very convenient for people to deal with routine tasks and all kinds of dull figures by computer in a more enjoyable way. Computers are human s friends and they are useful tools for people.The first computer in the history was named ENIAC

4、(Electronic Numerical Integrator and Computer) in 1946. It was quite huge and expensive. Ordinary people cannot afford it. Later on, since the contribution of human being ' s intelligence, computers are beco ming smaller and less expensive. Even ordinary people like you and mecan afford it today

5、.We can find various computers in the market today. People use computers in their daily life for studying, working or just for entertainment. The typical type of computer looks like a TV set. We call it desktop computer. You can find it in people' s offices, at homes orin net bars. This kind of

6、computer is often called PC(Personal Computer). In recent years, they are gradually replaced by another type of computer which is called notebook computer or laptop computer. The latter one is much smaller and more expensive than the former one. However, it is more convenient because it is small eno

7、ugh to put into a briefcase.What we called computers are not just those we have mentioned. Many other types of computers exist around us such as those in washing machines and ATMs. Computers really do a lot of favor to our daily life. They make our life more colorful, convenient and comfortable.Word

9、ping rapidly nowadays .由于當(dāng)今科技發(fā)展迅速since在這里表示“由于”的意思，引導(dǎo)原因狀語(yǔ)從句，例如：Since we are going to have our final exam, we should get wellprepared.由于快考試了，我們要做好充分的準(zhǔn)備。2. . all people are familiar with computer.所有的人者 B 對(duì)計(jì)算機(jī)很熟悉。be familiar with sth. 表示“對(duì)熟悉”,例如：We are all familiar with Jay Chou. He is a famous pop sta

10、r.我們都熟悉周杰倫，他是個(gè)著名的流行歌手。3. Everyone is keen on it.人人都對(duì)它著迷。be keen on sth./sb. 意思是“對(duì)著迷”，例如：It is said that Sarah is very keen on cute dolls.據(jù)說(shuō)薩拉對(duì)可愛(ài)的玩偶非常著迷。4. puters are becoming smaller and less expensive.計(jì)算機(jī)變得更小、更便宜了。smaller和less expensive都是比較級(jí)，比較級(jí)的表達(dá)方式有兩種。單音 節(jié)的詞的比較級(jí)或最高級(jí)直接在后面加“er”或“est"，如:small s

11、maller-smallest ；多音節(jié)的詞的比較極和最高級(jí)不能直接在原單詞上作變化，而是分 另U在前面力口 “more”或“most"，如：expensive more expensive most expensive。5. The latter one is much smaller and more expensive than the former one. 后者比前者更小、更貴。former 和 latter 是代詞，分別表示“前者 ”和“后者 ”。在這個(gè)句子中分別代表桌上型電腦和筆記本電腦。6. Computers really do a lot of favor to

They make our life more colorful, convenient and comfortable.它們使我們的生活變得豐富多彩, 方便快捷且舒適。colorful, convenient, comfortable 三個(gè)詞都是以c 開(kāi)頭 , 這在英文中是一種特殊的修辭手法押頭韻。 這種

13、方法常見(jiàn)于詩(shī)歌中的描寫，使用這種修辭手法能使文章變得緊湊生動(dòng), 朗朗上口。1 . Computer 小常識(shí)。計(jì)算機(jī)系統(tǒng)的主要部件包括存儲(chǔ)器、輸入設(shè)備、處理器和輸出設(shè)備。中央處理器(CPU)是所有計(jì)算機(jī)的核心部分。一般的計(jì)算機(jī)的CP"要由兩部分構(gòu)成: 算術(shù) /邏輯部分和控制部分。存儲(chǔ)器分為隨機(jī)存儲(chǔ)器(RAM)和只讀存儲(chǔ)器(ROM) RAM就是我們常說(shuō)的計(jì) 算機(jī)內(nèi)存，是使用最多的一種存儲(chǔ)類型。 ROMfc要用來(lái)存儲(chǔ)程序。ROM比RAM 速度要慢一些，因此，如果需要快速處理，可將ROW的內(nèi)容傳送到RAMfr去。計(jì)算機(jī)由以下幾個(gè)部分組成：mouse 鼠標(biāo)keyboard 鍵盤monitor

15、t least directly. Of course, they filled out computerized（ 使計(jì)算機(jī)化）forms, took computerized tests, and paid computerized bills. But the real work with computers was handled by specialists programmers （程序員）,data entry clerks（數(shù)據(jù)輸入員）,and computer operators（操作員）.Then microcomputers came along and changed

16、everything. Today it is easy for nearly everybody to use a computer. People whouse microcomputers are called end users. Now:Microcomputers（ 微型計(jì)算機(jī)） are common tools in all areas of life. Writers write, artists draw, engineers and scientists calculate （計(jì)算） all on microcomputers. Students and business
