Computer英語教學教案

  Teaching aims and demands

  本單元有關(guān)電腦的知識使用學生對其有一個初步的了解。讓學生了解有關(guān)中國民航運用計算機的情況。并學習如何使用向?qū)Ψ教峤ㄗh的口語練習,通過單詞的學習掌握go up, bring down, prefer to and, but although等詞的用法。本單元的語法重點是現(xiàn)在完成時被動語態(tài)的使用,要求學生能夠了解和掌握。

  Teaching important and difficult points

  1.Important Vocabulary:

  although, waste, believe, necessary, passenger, record, at one time, greatly, correct, complete, decision, abroad, change for

  2. Daily Expressions:

  First of all, …

  I believe…

  Any reason?

  3. Useful phrases:

  It would be a waste of …

  In my opinion, we should …

  4. Grammar

  The present perfect passive voice.

  教學建議

  1. 通過對話練習,進行兩個人之間對建議和推薦的用法。

  2. 通過課文的學習,掌握本單元的詞和詞組的用法。

  3. 通過對課外補充文章的學習,對計算機的歷史和應(yīng)用有所了解。

  Lesson 33: 口頭練習:對話交際功能——日常生活用語。

  Lesson 34: 學生進行對文章編成對話練習。練習直接引語變間接引語。

  Lesson 35: 學生繼續(xù)練習對話?梢园缪軨AAC的領(lǐng)導和記者,或計算機經(jīng)銷商和單位領(lǐng)導,或電視節(jié)目主持人和中學生等等。

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

  教材分析

  本單元的對話的特點是通過兩個人對買何種計算機的討論,從而掌握如何進行對一個物品進行評價、表達自己的觀點,并提出建議。比如常見的口語用法:In my opinion, we should… / What’s your opinion?/ I don’t think it’s necessary to …/ I believe …/ I still think … 就在這個對話中經(jīng)常出現(xiàn)。同時還有很多其它有用的口語,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算機的應(yīng)用對CAAC的幫助,而且中間穿插了很多現(xiàn)在完成進行時的被動語態(tài)的用法,使得學生能夠正確地掌握這個語法的用法。同時對一些常見詞和短語進行理解。比如:join, be used to do, thanks to, abroad, spend… on sth., prefer to do, welcome.

  重點知識講解

  1. Today they are talking about buying a new computer. 今天他們談?wù)撡I一個計算機。

  這里的talk about的意思是“談?wù)摚徽劶暗;討論”,后面通常加上名詞或動名詞。

  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的價格了么?

  這里的詞組find out和find都是表示“找出”,都是一個結(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)過一番努力或研究得出的結(jié)果的時候,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)得到了所有計算機的信息了。

  這里的`information同news一樣是一個不可數(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,我們應(yīng)該買IBM PC 586。

  這里的in one’s opinion表示的意思是“依…來看;…的意見是”。需要注意兩點:

  1)后面不加I/he…think(s)。不像中文里可以說“依我看來,我覺得…”。在英語中這兩種用法不同時出現(xiàn)。

  In my opinion, you are the best student. 不能說成 In my opinion, I think you are the best student.

  2)后面不加客觀事實。因為這里應(yīng)是一個推斷或主觀的意見,比如:

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

  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更大的計算機。

  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. 它還記錄下游客購票的情況。

  句子中的be used to的意思是“被用來…”,是一個被動語態(tài),后面加上動詞原型。

  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)在要找到哪架飛機滿了比以前要快多了。

  這里用了一個much表示一個程度。通常在much, even和still后面加上一個形容詞或副詞的比較級形式。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. 由于使用了新的計算機,乘客在中國民航購票快多了。

  句子中的thanks to是一個常見的短語,表示“由于;幸虧”,相當于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,中國民航辦公室前等著購票的人們排成長長的隊列。

  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. 我們歡迎這些人來乘坐我們的飛機。

  這里的welcome在這句話中是一個形容詞,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也可以作為一個及物動詞,但后面不加不定式,而且過去式和過去分詞都是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,我們應(yīng)該買IBM PC 586。

  這里的情態(tài)動詞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更大的計算機。

  這里的if是一個條件句。后面出現(xiàn)的兩個逗號之間的東西從位置上說是一個插入語,從成份上來說是一個同位語,是對前面的名詞the smaller one進行解釋。我們通常用一個名詞性短語或從句來作為同位語

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

  我們通常在think, suppose, expect, imagine等表示心理活動的動詞后面不加否定含義的賓語從句。如果后面的從句使一個否定句,我們常常將從句謂語動詞的否定是轉(zhuǎn)移到主句的謂語動詞之前。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對我們來說就夠大的了。

  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. 我們不可以在浪費更多的時間了。

  這里的情態(tài)動詞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。

  這里的which one to buy為特殊不定式短語,在句子中做decide的賓語。特殊不定式的構(gòu)成形式為“關(guān)系代詞或關(guān)系副詞+動詞不定式”。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
