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: 學生繼續練習對話�？梢园缪軨AAC的領導和記者，或計算機經銷商和單位領導，或電視節目主持人和中學生等等。
Lesson 36: 筆頭練習：讓學生寫一篇關于自己生活中計算機的使用的文章，或對計算機在人們生活中應用的暢想。
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 … 就在這個對話中經常出現。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用對CAAC的幫助，而且中間穿插了很多現在完成進行時的被動語態的用法，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. 今天他們談論買一個計算機。
這里的talk about的意思是“談論；談及到；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”，都是一個結果。但是兩種也有區別：如果表示意外發現，通常用find。比如：
I found this wallet outside the classroom.
What did you find just now?
如果要表示經過一番努力或研究得出的結果的時候，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一樣是一個不可數名詞。后面通常加上for或about，前面通常加上一些修飾不可數名詞的形容詞。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。比如：
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，后面加上動詞原型。
The water her is used to make the trees alive.s are used here to play games on.
8. Now it is possible to find out much faster which planes are full. 現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”。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，我們應該買IBM PC 586。
這里的情態動詞should表示的意思是“應該”，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。特殊不定式的構成形式為“關系代詞或關系副詞+動詞不定式”。常用的關系代詞有：what, which, who, whether等；常用的關系副詞有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 where to live.
18. 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。
這里的waiting是一個現在分詞，在句子中做people的定語，放在名詞后，相當于一個定語從句。比如：
The foreigner talking with our teacher is head of the visiting group.
The man running after the bus is a friend of mine.
19. As a result, the number of people who travel by plane in China is larger than ever before. 因此，在中國乘飛機旅行的人數比以往多了。
這句話中的as a result的作用相當于一個副詞，意思相當于so。比如：
He hurt himself. As a result, he couldn’t go to school.
這句話中的the number of 的中心詞是number，說明謂語動詞肯定是單數的。比如：
The number of the books in this bookshop is more than 200,000.
20. 我們在很多句子中都用一個代詞來代替前面提到的名詞，常見的有one, it和that。這三個詞都是代詞的時候的區別：
1, one=a/an +noun 所代表的是前面提到的同類中的任何一個
He has no book and no money to buy one.
The hat is too small. Please show me a larger one.
2, it=the/this/that/adj.+ noun 指同一件事物
He has a book, but he will not lend it to me.
I drank some iced water, but it made me more thirsty.
3, that =the + noun 指前面所提到的同一類中的另外制定的一個.
The air of the country is purer than that of the city.
比較下面三句話：
I cannot find my umbrella; I think I must buy one.
I cannot find umbrella; I don’t know where I put it.
The umbrella you bought is cheaper than that I bought.

一、閱讀理解
we are already familiar with computers—computers work for us at home, in offices and in factories. but it is also true that many children today are using computers at schools before they can write. what does this mean for the future? are these children lucky or not?
many people who do not know about computers think of them as machines that children play with. they worry that children do not learn from experience but just from pressing a button and that this is not good for them. they think that children are growing not knowing about the real world.
but people who understand more about computers say that computers can be very good for children. a computer can help them to learn about the real world more quickly, to learn what they want to learn and think for themselves. and for the future, don’t we need people who can think clearly, who know how to get information quickly and use it well? what do you think?
1. “to be familiar with” means to ______.
a. know nothing b. know about c. dislike d. like
2. does everyone think computers are good for children?（ ）
a. yes, they do. b. no, not everyone thinks so.c. they don’t know. d. they are not sure.
3. what can computers help children to do?（ ）

Computer 篇10
動詞時態 一、經過前幾個單元的學習，到這個單元為止，時態已經學完。按照要求，學生需要掌握下列幾個重要時態。 1、一般現在時。 1》概念 其基本意義在于表示發生在包括講話時間在內的動作或狀態。 2》理解：本時態主要關注動作的經常性，強調動作表現的事實，或者是真理，而且和現在有關。 〈1〉表示客觀真理，科學事實，格言，及其它各種不受時間限制的客觀存在狀況。 如： light travels faster than sound action speaks louder than words <2> 表示經常性或習慣性的動作。 如；our art teacher practises painting twice a day. tom often regularly drop in on the professor. <3> 表示現在的特征或狀態。 如：he is always ready to help others. tom seldom rises at six. <4> 有when/ while/ until/ before/ as soon as/if /even if等引導的時間，條件，或讓步壯語從句中，常用一般現在時。 如：when we get there,we'll call you. no one can go through with the task on time if it rains. i'll not attend her birthday party even if i am invited. <5> 在新聞標題，小說，戲劇，電影，圖片等說明中，也經常用一般現在時。 如：the delegation of china gets a warm welcome in russia. the story is about a family---.the husband comes home from his office and tells the wife that he has invited a friend to dinner. 3》標志：often/always/usually/seldom./never..對上述壯語提問時，常用 how often...? 肯定句中，動詞用第三人稱單數形式。 如: ---how often does he visit the old man? —---never. 2.一般過去時 1》概念 本時態主要是表示過去的時間內發生的動詞作或者是狀態。 2》理解 強調過去動作的一次性和習慣性。 <1> 表示過去特定時間的一次完成的動作。 如： the old professor stepped into the classroom, opened the book, and began to read. we went to beijing and visited heaven temple. <2> 用它表示習慣性動作，往往用一定的時間狀語或表示頻度的狀語。 如：we went to school together when we were boys and so we saw each other every day. there used to a temple in the village. 在日常會話中，我們也用一般過去時表示現在的時間。這種用法在講話的口氣上表現出婉轉，客氣的意味。 如： ---did you want me ? ----yes,i hoped you could give me a hand with the painting. 3》警示：除了表示明顯的過去時間狀語外，還有used to/would等暗示性詞語。 如：when i was in london, often,i would have a cup of coffee after work. 注意：上句中的would 不能用 used to 代替。這兩個詞雖然都表示"過去常常",但would 常和時間連用，如 often, every day 等，而used to 不可以。 3。一般將來時 1》概念 表示將來要發生的動作。 2》理解 對未來事情的預見性，或者說明意圖，打算。 <1> 用will 或shall +動詞的形式表示對未來事情的預見性，又稱為預見性將來時。 如： tomorrow will be fine . you will feel better after taking the medicine. <2> 用 be going to do表示將來。 用這種形式表示將來主要是說明現在的意圖，打算，即表明眼前最近要去做的事情。又稱之為近期將來。如：i'm going to post two letters after class./she is going to have a university degree. 如果這種結構用物做主語，也是一種預見，可以用will 代替。 如：it is going to rain watch out!the pill of boxes is going to fall. <3> 用be+going 表示將來 一般說來，用現在進行時表示將來所用的時間大都是動作動詞，不適用于狀態動詞。用這種結構表示按計劃要去做的事或發生的事情。 如：we're inviting several people to a party. the foreign ministry is coming to the un this week. the plane is taking off at 5:30 一般來說，be doing / be going to do 兩種結構均可以表示將來，但有些區別。 比較：i am taking mary out for dinner tonight . i am going to take mary out for dinner tonight. 第一句表示計劃已定不能改變，第二句表示打算未定只是一種想法而已。 <4> 用be+to do 表示將來時間 這種結構也可以表示按計劃，隨安排將要去做的事情或將要發生的動作。 如；the workers are to produce 5000 cars next year. the prime minister is to speak on television tonight. the line is to be open to traffic on october 1. 這種結構表示的將要發生的動作一般來說受人們意志控制或支配的�？梢曰Q，但語意上有區別。如： we are going to play basketball this afternoon.<表示目前的意圖> we are to play basketball this afternoon.<表示計劃，安排或受人的支配>. 我們可以說：it's going to rain /the young man is going to be fat. 但不能說：it is to rain/the young man is to be fat. <5>用一般現在時表示將來。 如：next christmas falls on a tuesday the train leaves at 7:30 this evening . the plane takes off at 6:40. 3》警示 除了上述那些之外，也用be about to/be on the point of /be on the middle of/ 表將來。 如：the meeting is about to begin. we are on the point of going out ... 但值得注意的是這種形式不和將來的時間用在一起。我們不可以說they are about to leave this afternoon. 4。進行時 1》概念 表示某時某刻某階段正在進行的動作。 2》理解 進行的動作包括現在，過去和將來。 <一> 現在進行時 本結構是am/is/are+doing構成的形式。這種時態表示的動作主要與現在時間有關系。有如下的用法。 <1> 表示此刻正在進行或發生的動作 常伴有時間狀語。如：now/at present/ at the moment at present, the staff are holding a meeting. where are they having the basketball match ? <2> 表示現階段正在進行的動作。 i usually get up at seven, but i'm getting up at six every day this week to prepare my lessons. selecting a mobile phone is difficult. the technology is changing . <3> 如果和表示頻度的時間狀語連用，不表示動作的進行，而表示動作的重復性，在語意上帶有感情色彩。如： you are continually finding fault with me.<表不滿》 he is always thinking of how he could do for the people《表贊揚〉 the old man is constantly complaining of his watch being slow.〈發牢騷〉 〈二〉過去進行時。 本結構是was/were+doing 構成的形式。它表示的狀態或動作主要和過去的時間有聯系，所以往往和表示過去的時間連用。 〈1〉表示過去某時刻正在進行的動作。如： what were you doing at ten last night? when i got up this morning, it was raining outside. <2> 表示過去某階段中正在進行的動作。如： at that time, he was working in a pla unit. in those years he was having a happy life. <3> 在敘述故事的背景時，為了使故事的語言更加生動，讓讀者有身臨其境的效果，多用進行時。如：one morning the three sisters were together in the drawing room.mary was sewing, alice was playing the piano, and jane was doing nothing, then suddenly the door opened... 正如現在進行時一樣，過去進行時與表示頻度的時間狀語連用，也能表示某種情感色彩。 3》警示 進行時還常用在語境中，表示語氣的委婉。如： ---what are you going to do? ---i'm hoping to invite you to dinner. 5.完成時。 1》概念 本時態是表示某動作或某過程在一定時間內處于完成的狀態。 2》理解 完成時包括現在完成時和過去完成時態。構成分別為have<has> done/had done. <一>現在完成時。動作在過去發生，持續到現在已經完成，或者是繼續持續下去。 <1> 已經完成的用法。其表明某動作或過程發生在說話前某個不明確的過去時刻，到目前一完成，并對目前造成影響。如：he has not been to shanghai/have you finished reading the story ? 本用法常和不確定時間狀語連用。如：already/yet/before/recently/lately/just...等 i have seen him before we haven't been there lately 也可以和表示頻度的時間狀語用在一起。如：ever/never/once---等。 i have never been to hongkong. have you ever visited the great wall ? <2> 未完成的用法。本用法表示某動作或狀態開始于過去某個時刻一直延續到現在，而且還要繼續下去，在某種情況下也可能剛剛結束。常和 since/for/時間狀語連用。如： he has been in the army for 3 years. he has lived in the building since he came here. 3》警示：如果不過since 引導的從句中的動詞是延續性的，一般認為，語意上也表明動作或狀態的結束。如： i haven't heard from him since he lived there. 從他離開那兒以來，我一直未收到他的消息。 he has written to me frequently since i was ill. 從我病愈以來，他常給我寫信。 如果since引導的從句中的謂語動詞用了現在完成時，那么表示的動作或狀態就不表示完結。如： i haven't heard from him since he has lived there . 從我住在那里以來，我一直未收到他的來信。 he has written to me frequently since i have been ill. 從我生病以來，他常給我寫信。 <二>過去完成時。本時態表示的是動作在過去的過去發生。它也分為“已完成用法”和“未完成用法”。 1>已完成用法。表示，當一個動作發生或結束時，在它之前的另一動作已經完成。這種用法既用于動作動詞，也用于狀態動詞。如： when we arrived the cinema,the tickets have been sold out. tom flew home,but his father had already died. iwas told that the old man had been away for a week. 2>未完成用法。表明某個動作或狀態在過去某個時刻之前一直延續到過去這個時間，而且還可能繼續下去。它也使用于動作和狀態動詞。而且常和 by +過去時間 或從句 連用。如： by 12,he had studied for 4 hours. by we got there,they had ended the meeting. we had worked together for a long time before we came to this college . 3>警示：在by + 過去時間或從句的結構中，如果主句動詞是動作動詞，用過去完成時，如果是狀態動詞，用一般過去時。比較： by the end of last year,he was 12. by the end of last year,he had learned 300 english words. 另外，在---hardly---when/ ---no sooner---than---的句中，主句用過去完成時，從句用一般過去時。而且，如果hardly./no sooner 提前，主句需要部分倒裝。如： i had hardly recoganized him when i saw him. hardly had i recoganized him when i saw him.

句型梳理
1【教材原句】 as time went by，i was made smaller.(p18)
隨著時間的流逝，我被做得更小了。
【句法分析】 as意為“隨著”，引導時間狀語從句。

隨著年齡的增長，我們會變得越來越聰明。

[即境活用]

a.while b.when
c.as d.with
解析：選c。as可表示兩個同步發展的動作或行
為，意為“隨著”；while表示一段較長的時間或過程內主從句謂語動作同時發生；when作“當……的時候”講，指較短的一段時間或點時間；with不能引導從句。
12.i couldn’t do my homework with all that noise________.
a.going on b.goes on
c.went on d.to go on
解析：選a。with復合結構在句子中作伴隨狀語。“with＋n.＋doing/done/介詞短語”為固定結構。noise與go on之間為主動關系，故選a。
2【教材原句】 and my memory became so large that even i couldn’t believe it！(p18)
我的存儲量變得如此之大，連我自己都不能相信！
【句法分析】 so/such...that引導結果狀語從句，意為“如此……以至于”。

(2)當so.../such...放在句首時，主句要用部分倒裝。
�、辳o fast did the teacher speak that i couldn’t follow him.
(the teacher spoke so fast that i couldn’t follow him.)
那個老師說得太快，我聽不懂。
[即境活用]
13.(XX年高考上海卷)the great wall is________tourist attraction that millions of people pour in every year.
a.so a wellknown b.a so wellknown
c.such wellknown a d.such a wellknown
解析：選d。句意：長城是如此著名的旅游勝地，以至于每年都有上百萬人涌來。such＋a＋形容詞＋單數名詞＋that從句，表示“如此……以至于……”。
14.(XX年高考重慶卷)peter was so excited________he received an invitation from his friend to visit chongqing.
a.where b.that
c.why d.when
解析：選d。句意：當彼得的朋友邀請他來重慶時，他很興奮。此題考查狀語從句，只有when引導的時間狀語從句符合題意。
復合句
◆什么是復合句
復合句由一個主句和一個或多個從句組成，主句表達的是重要信息，從句起到補充修飾的作用。一個組織嚴密的復合句通常在包含大量信息的同時，還要正確地反映信息間的邏輯關系。
【佳句選粹】
�、賢here is a rumor that he has married a widow.
【分析】 本句屬于復合句，由“主句＋同位語從句”構成。“he has married a widow”作為“rumor” 的同位語，由that引導構成了同位語從句。
�、趌et’s meet tomorrow if it is convenient for you.
【分析】 本句屬于復合句，由“主句＋條件狀語從句”構成�！發et’s meet tomorrow”是主句，“if it is convenient for you”是由if引導的條件狀語從句。
◆主要從句類型
英語中的從句有很多類型，因此除了準確判斷句子之間的主從關系以外，還要熟悉和掌握各種不同類型的從句。
1.名詞性從句：它在句子中可充當主語、賓語、表語、同位語等。
【佳句選粹】
�、賖ow it all happened is a mystery to me.
這一切是怎樣發生的對我來說是個謎。(主語)
�、趇 wonder if you could stay for another day.
不知你可否再待一天。(賓語)
�、踭he question is whether they have signed a contract.
問題是他們簽沒簽合同。(表語)
④the idea that money means everything is unsound.
金錢萬能的思想是錯誤的。(同位語)
2.定語從句：多由關系代詞或關系副詞引導。
【佳句選粹】
�、賘im introduced me to a girl who sat next to him.
吉姆把我介紹給他旁邊的一位姑娘。
�、趖hen i telephoned the doctor (whom)she had recommended.然后我給她推薦的醫生打了電話。
�、踭here are the reasons why we did it.
這些就是我們這樣做的原因。
3.狀語從句：用作狀語的從句很多，可以表示時間、地點、原因、條件、方式、目的、結果、比較、讓步等。
【佳句選粹】
�、賥e all stood up when he came in.
他進來時我們都站了起來。(時間)
�、趇 didn’t go because i wasn’t feeling well.
我沒有去是因為我身體不舒服。(原因)
�、踚t was so dark that we couldn’t see each other’s faces.
天那樣黑，我們看不清彼此的臉。(結果)
④though they were poor，they were still happy.
他們雖然很窮，但仍然很幸福。(讓步)
⑤just as the water is the most important of liquids，air is the most important of gases.
正如水是液體中最重要的一種一樣，空氣是氣體中最重要的一種。(方式)
�、辻ou’ll do all right，as long as you follow his advice.
只要你聽從他的勸告，你就會干得很好。(條件)
�、遲he director gave me a better offer than he gave dick.
導師給我的提議比給狄克的好。(比較)

�。ǘ┱n后寫作練習題答案
知識總結與歸納
�。ㄒ唬┍菊抡Z法知識講解
形容詞比較級和最高級
as + 形容詞或副詞原級 + as
1）在否定句或疑問句中可用so… as.
he cannot run so/as fast as you.
2）當as… as 中間有名詞時采用以下格式。
as +形容詞+ a +單數名詞
as + many/ much +名詞
this is as good an example as the other is.
i can carry as much paper as you can
3）用表示倍數的詞或其他程度副詞做修飾語時，放在as的前面。
this room is twice as big as that one.
your room is the same size as mine.
4）倍數+ as + adj. + as <=> 倍數+ the + n + of
th is bridge is three times as long as that one.
this bridge is three times the length of that one.
your room is twice as large as mine.
your room is twice the size of mine.
比較級形容詞或副詞 + than
you are taller than i.
they lights in your room are as bright as those in mine.
注意：
1）要避免重復使用比較級。
�。ㄥe）he is more cleverer than his brother.
�。▽Γ﹉e is more clever than his brother.
（對）he is clever than his brother.
2）要避免將主語含在比較對象中。
�。ㄥe）china is larger that any country in asia.
（對）china is larger than any other countries in asia.
3）要注意對應句型，遵循前后一致的原則。
the population of shanghai is larger than th at of beijing.
it is easier to make a plan than to carry it out.
4）要注意冠詞的使用，后有名詞的時候，前面才有可能有名詞。
比較：
wh ich is large，canada or australia？
which is the larger country，canada or australia？
she is taller than her two sisters.
she is the taller of the two sisters.
可修飾比較級的詞
1）a bit，a little，rather，much，far，by far，many，a lot，lots，a great deal，any，still，even等
2）還可以用表示倍數的詞或度量名詞作修飾語。
3）以上詞（除by far）外，必須置于比較級形容詞或副詞的前面。
man y，old 和far
1）如果后接名詞時，much more +不可數名詞
many more +可數名詞復數
2）old 有兩種比較級和最高級形式：older/oldest 和elder/eldest. elder，eldest 只用于兄弟姐妹的長幼關系。
my elder brother is an engineer.
mary is the eldest of the three sisters.
3）far 有兩種比較級，farther，further. 在英語中兩者都可指距離。
在美語中，farther 表示距離，furthe r表示進一步。
i have nothing further to say.
the + 最高級 + 比較范圍
1）the sahara is the biggest desert in the world.
形容詞最高級前通常必須用定冠詞 the，副詞最高級前可不用。
形容詞most前面沒有 the，不表示最高級的含義，只表示“非�！�。
it is a most important problem.
=it is a very important problem.
注意：使用最高級要注意將主語包括在比較范圍內。
�。ㄥe）tom is the tallest of his three brothers.
（對）tom is the tallest of the three brothers.
2）下列詞可修飾最高級，by far，far，much，mostly，almost
this hat is nearly / almost the biggest.

this is the very best.

b. 序數詞通常只修飾最高級。

3）句型轉換：

p29 a
dear gran
yesterday, mum and dad gave us two radio-controlled cars for our birthday. they are great! nigel’s car is a ‘lightning’. it is (1) faster than mine, which is rather slow. my car is a ‘hi-climb’, and it is (2) better at climbing over things than the ‘lightning’. the ‘lightning’ is (3) longer and (4) lower th an the ‘hi-climb’. the ‘hi-climb’ weights 210 g and so it is (5) heavier than the ‘lightning’, and this means that the battery use is heavier (6) than the ‘lightning’, too.
the ‘lightning’ is (7) lighter, with a weight of just 150 g. this means that is can go (8) farther on one set of batteries. sometimes we put toy people in the cars. the ‘hi-climb’ can hold (9) more passengers, as it has 4 seats. the ‘lightning’ is good on a flat surface, but it is (10) worse than the ‘hi-climb’ on rough ground, because it cannot climb over things.
love

p30 b
dear peter
thanks for your letter. in reply to the question at the end, my parents have just bought a new flat! they looked at one in peak villa and one in seaside court. they chose peak villa. the flat there is bigger than the flat in seaside court, but it has fewer rooms. it is also more modern, and its price is higher. it is nearer to the school, but it is farther from the market. finally, the view from peak villa is better than the view from seaside court. i’ll send you a photo in my next letter.
best wishes
robin
