Computer英語(yǔ)教案

  作為一位不辭辛勞的人民教師,總歸要編寫教案,編寫教案有利于我們科學(xué)、合理地支配課堂時(shí)間。那么你有了解過(guò)教案嗎?下面是小編整理的Computer英語(yǔ)教案,希望對(duì)大家有所幫助。

Computer英語(yǔ)教案

  教學(xué)目標(biāo)

  本單元有關(guān)電腦的知識(shí)使用學(xué)生對(duì)其有一個(gè)初步的了解。讓學(xué)生了解有關(guān)中國(guó)民航運(yùn)用計(jì)算機(jī)的情況。并學(xué)習(xí)如何使用向?qū)Ψ教峤ㄗh的口語(yǔ)練習(xí),通過(guò)單詞的學(xué)習(xí)掌握go up, bring down, prefer to and, but although等詞的用法。本單元的語(yǔ)法重點(diǎn)是現(xiàn)在完成時(shí)被動(dòng)語(yǔ)態(tài)的使用,要求學(xué)生能夠了解和掌握。

  教學(xué)重難點(diǎn)

  Lesson 36:筆頭練習(xí):讓學(xué)生寫一篇關(guān)于自己生活中計(jì)算機(jī)的使用的文章,或?qū)τ?jì)算機(jī)在人們生活中應(yīng)用的暢想。

  教材分析

  本單元的對(duì)話的特點(diǎn)是通過(guò)兩個(gè)人對(duì)買何種計(jì)算機(jī)的討論,從而掌握如何進(jìn)行對(duì)一個(gè)物品進(jìn)行評(píng)價(jià)、表達(dá)自己的觀點(diǎn),并提出建議。比如常見的口語(yǔ)用法:In my opinion, we should… / What’s your opinion?/ I don’t think it’s necessary to …/ I believe …/ I still think …就在這個(gè)對(duì)話中經(jīng)常出現(xiàn)。同時(shí)還有很多其它有用的口語(yǔ),比如:First of all…/ in a few years’ time/ a waste of …/ make a decision/ not … any more

  本單元的課文不僅講述了計(jì)算機(jī)的應(yīng)用對(duì)CAAC的幫助,而且中間穿插了很多現(xiàn)在完成進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)的用法,使得學(xué)生能夠正確地掌握這個(gè)語(yǔ)法的用法。同時(shí)對(duì)一些常見詞和短語(yǔ)進(jìn)行理解。比如:join, be used to do, thanks to, abroad, spend… on sth., prefer to do, welcome.

  重點(diǎn)知識(shí)講解

  1. Today they are talking about buying a new computer.今天他們談?wù)撡I一個(gè)計(jì)算機(jī)。

  這里的talk about的意思是“談?wù);談及到;討論”,后面通常加上名詞或動(dòng)名詞。

  We talked about it yesterday.

  I want to talk about the price of the car with you.

  2. Did you find out the price for the IBM PC 486?你找出IBM PC 486的價(jià)格了么?

  這里的詞組find out和find都是表示“找出”,都是一個(gè)結(jié)果。但是兩種也有區(qū)別:如果表示意外發(fā)現(xiàn),通常用find。比如:

  I found this wallet outside the classroom.

  What did you find just now?

  如果要表示經(jīng)過(guò)一番努力或研究得出的結(jié)果的時(shí)候,find和find out都可以,但通常用后者。比如:

  I finally found out the secret of his death.

  She wanted to find out the real answer to the question.

  3. I’ve got the information for all the computers now.我已經(jīng)得到了所有計(jì)算機(jī)的信息了。

  這里的information同news一樣是一個(gè)不可數(shù)名詞。后面通常加上for或about,前面通常加上一些修飾不可數(shù)名詞的形容詞。比如:

  Do you have any information about the new machine.

  4. In my opinion, we should buy the IBM PC 586.依我看來(lái),我們應(yīng)該買IBM PC 586。

  這里的in one’s opinion表示的意思是“依…來(lái)看;…的意見是”。需要注意兩點(diǎn):1)后面不加I/he…think(s)。不像中文里可以說(shuō)“依我看來(lái),我覺得…”。在英語(yǔ)中這兩種用法不同時(shí)出現(xiàn)。比如:

  In my opinion, you are the best student.不能說(shuō)成In my opinion, I think you are the best student.

  2)后面不加客觀事實(shí)。因?yàn)檫@里應(yīng)是一個(gè)推斷或主觀的意見,比如:

  In my opinion, the earth is round. (錯(cuò)誤句子)。

  In my opinion, you are right. (正確句子)

  5. If we buy the smaller one, the IBM PC 486, we might have to change it in a few years’ time for a bigger one.如果我們現(xiàn)在要是買了the IBM PC 486,幾年以后我們肯定要換一個(gè)更大的計(jì)算機(jī)。

  這里的詞組change… for…表示的意思是“將…換成…”。比如:

  I want to change this small hat for a bigger one.

  6. I hope we can make a decision today.我希望我們今天能做出決定。

  這里的詞組是make a decision(做出決定)。等于decide to do。比如:

  Did they make a decision yesterday?

  另外也可以用come to a decision, arrive at a decision來(lái)表示同樣的意思。比如:

  They finally came to a decision at the meeting.

  7. It is used to record the tickets which passengers buy.它還記錄下游客購(gòu)票的情況。

  句子中的be used to的意思是“被用來(lái)…”,是一個(gè)被動(dòng)語(yǔ)態(tài),后面加上動(dòng)詞原型。

  The water her is used to make the trees alive.

  Computers are used here to play games on.

  8. Now it is possible to find out much faster which planes are full.現(xiàn)在要找到哪架飛機(jī)滿了比以前要快多了。

  這里用了一個(gè)much表示一個(gè)程度。通常在much, even和still后面加上一個(gè)形容詞或副詞的比較級(jí)形式。比如:

  I am much heavier than before.

  She is much happier than she was two years ago.

  9. Thanks to the new computer, the passengers at the offices of the CAAC can now buy their aeroplane tickets much faster.由于使用了新的計(jì)算機(jī),乘客在中國(guó)民航購(gòu)票快多了。

  句子中的thanks to是一個(gè)常見的短語(yǔ),表示“由于;幸虧”,相當(dāng)于because of,或者as a result of表示原因。比如:

  Thanks to your help, I was able to win the game.

  They lost the game thanks to the foolish advice you gave them.

  10. At one time, there were long queues of people waiting outside the CAAC offices.以前,中國(guó)民航辦公室前等著購(gòu)票的人們排成長(zhǎng)長(zhǎng)的隊(duì)列。

  詞組at one time表示的意思是“以前;曾經(jīng)”。比如:

  At one time we met each other every day.

  He went to that restaurant to have dinner at one time.

  11. These people will be welcome on our planes.我們歡迎這些人來(lái)乘坐我們的飛機(jī)。

  這里的welcome在這句話中是一個(gè)形容詞,表示的意思是“受歡迎的”,后面常加的是不定式。比如:

  You are welcome to do anything you like.

  Welcome to Beijing.

  welcome這個(gè)詞也可以是名詞。比如:

  They received a cold welcome when they arrived.

  同樣welcome也可以作為一個(gè)及物動(dòng)詞,但后面不加不定式,而且過(guò)去式和過(guò)去分詞都是welcomed。比如:

  All the students welcomed the visiting friends at the school gate.

  12. In my opinion, we should buy the IBM PC 586.依我看來(lái),我們應(yīng)該買IBM PC 586。

  這里的情態(tài)動(dòng)詞should表示的意思是“應(yīng)該”,通常用在表示建議的句子中。比如:

  I should go home before 6 o’clock.

  You should not ask others to do your homework.

  13. If we buy the smaller one, the IBM PC 486, we might have to change it in a few years’ time for a bigger one.如果我們現(xiàn)在要是買了IBM PC 486,幾年以后我們肯定要換一個(gè)更大的計(jì)算機(jī)。

  這里的if是一個(gè)條件句。后面出現(xiàn)的兩個(gè)逗號(hào)之間的東西從位置上說(shuō)是一個(gè)插入語(yǔ),從成份上來(lái)說(shuō)是一個(gè)同位語(yǔ),是對(duì)前面的名詞the smaller one進(jìn)行解釋。我們通常用一個(gè)名詞性短語(yǔ)或從句來(lái)作為同位語(yǔ)

  14. I don’t think I it’s necessary to buy the bigger one.我想沒(méi)必要買較大的那個(gè)。

  我們通常在think, suppose, expect, imagine等表示心理活動(dòng)的動(dòng)詞后面不加否定含義的賓語(yǔ)從句。如果后面的從句使一個(gè)否定句,我們常常將從句謂語(yǔ)動(dòng)詞的否定是轉(zhuǎn)移到主句的謂語(yǔ)動(dòng)詞之前。比如:

  I don’t think I can get away at the moment.

  I don’t suppose you need to worry.

  I don’t think I know you.

  15. The IBM PC 486 will be big enough for us. IBM PC 486對(duì)我們來(lái)說(shuō)就夠大的了。

  句子中的enough可以是形容詞,也可以是副詞。通常我們將enough放在名詞前面或形容詞或副詞的后面。而且通常在后面再加上不定式。比如:

  I don’t have enough money to buy a house.

  I am not rich enough to buy a house.

  16. We mustn’t waste any more time.我們不可以在浪費(fèi)更多的時(shí)間了。

  這里的情態(tài)動(dòng)詞mustn’t表示的不是“必須不”而是“不可以;不允許”。通常用在命令的句子中。比如:

  You mustn’t talk in class. It is not a good habit.

  We mustn’t go there because it is dangerous.

  17. We must decide which one to buy.我們必須決定買哪一個(gè)。

  這里的which one to buy為特殊不定式短語(yǔ),在句子中做decide的賓語(yǔ)。特殊不定式的構(gòu)成形式為“關(guān)系代詞或關(guān)系副詞+動(dòng)詞不定式”。常用的關(guān)系代詞有:what, which, who, whether等;常用的關(guān)系副詞有how, when, where, why等。比如:

  We haven’t decided what to do next.

  I don’t know how to write in English.

  I will ask when to start tomorrow morning.

  She will ask wher
