2. 通过课文的学习，掌握本单元的词和词组的用法。
3. 通过对课外补充文章的学习，对计算机的历史和应用有所了解。
Lesson 33: 口头练习：对话交际功能——日常生活用语。
Lesson 34: 学生进行对文章编成对话练习。练习直接引语变间接引语。
Lesson 35: 学生继续练习对话。可以扮演CAAC的领导和记者，或计算机经销商和单位领导，或电视节目主持人和中学生等等。
Lesson 36: 笔头练习：让学生写一篇关于自己生活中计算机的使用的文章，或对计算机在人们生活中应用的畅想。
教材分析
本单元的对话的特点是通过两个人对买何种计算机的讨论，从而掌握如何进行对一个物品进行评价、表达自己的观点，并提出建议。比如常见的口语用法：In my opinion, we should… / What’s your opinion?/ I don’t think it’s necessary to …/ I believe …/ I still think … 就在这个对话中经常出现。同时还有很多其它有用的口语，比如：First of all…/ in a few years’ time/ a waste of …/ make a decision/ not … any more
本单元的课文不仅讲述了计算机的应用对CAAC的帮助，而且中间穿插了很多现在完成进行时的被动语态的用法，使得学生能够正确地掌握这个语法的用法。同时对一些常见词和短语进行理解。比如：join, be used to do, thanks to, abroad, spend… on sth., prefer to do, welcome.
重点知识讲解
1. Today they are talking about buying a new computer. 今天他们谈论买一个计算机。
这里的talk about的意思是“谈论；谈及到；讨论”，后面通常加上名词或动名词。
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的价格了么？
这里的词组find out和find都是表示“找出”，都是一个结果。但是两种也有区别：如果表示意外发现，通常用find。比如：
I found this wallet outside the classroom.
What did you find just now?
如果要表示经过一番努力或研究得出的结果的时候，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. 我已经得到了所有计算机的信息了。
这里的information同news一样是一个不可数名词。后面通常加上for或about，前面通常加上一些修饰不可数名词的形容词。比如：
Do you have any information about the new machine.
4. In my opinion, we should buy the IBM pC 586. 依我看来，我们应该买IBM pC 586。
这里的in one’s opinion表示的意思是“依…来看；…的意见是”。需要注意两点：1）后面不加I/he…think(s)。不像中文里可以说“依我看来，我觉得…”。在英语中这两种用法不同时出现。比如：
In my opinion, you are the best student. 不能说成 In my opinion, I think you are the best student.
2)后面不加客观事实。因为这里应是一个推断或主观的意见，比如：
In my opinion, the earth is round. (错误句子)。
In my opinion, you are right. (正确句子)
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. 如果我们现在要是买了the IBM pC 486，几年以后我们肯定要换一个更大的计算机。
这里的词组change… for…表示的意思是“将…换成…”。比如：
I want to change this small hat for a bigger one.
6. I hope we can make a decision today. 我希望我们今天能做出决定。
这里的词组是make a decision(做出决定)。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来表示同样的意思。比如：
They finally came to a decision at the meeting.
7. It is used to record the tickets which passengers buy. 它还记录下游客购票的情况。
句子中的be used to的意思是“被用来…”，是一个被动语态，后面加上动词原型。
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. 现在要找到哪架飞机满了比以前要快多了。
这里用了一个much表示一个程度。通常在much, even和still后面加上一个形容词或副词的比较级形式。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. 由于使用了新的计算机，乘客在中国民航购票快多了。
句子中的thanks to是一个常见的短语，表示“由于；幸亏”，相当于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，中国民航办公室前等着购票的人们排成长长的队列。
词组at one time表示的意思是“以前；曾经”。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. 我们欢迎这些人来乘坐我们的飞机。
这里的welcome在这句话中是一个形容词，表示的意思是“受欢迎的”，后面常加的是不定式。比如：
You are welcome to do anything you like.
Welcome to Beijing.
welcome这个词也可以是名词。比如：
They received a cold welcome when they arrived.
同样welcome也可以作为一个及物动词，但后面不加不定式，而且过去式和过去分词都是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. 依我看来，我们应该买IBM pC 586。
这里的情态动词should表示的意思是“应该”，通常用在表示建议的句子中。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. 如果我们现在要是买了IBM pC 486，几年以后我们肯定要换一个更大的计算机。
这里的if是一个条件句。后面出现的两个逗号之间的东西从位置上说是一个插入语，从成份上来说是一个同位语，是对前面的名词the smaller one进行解释。我们通常用一个名词性短语或从句来作为同位语
14. I don’t think I it’s necessary to buy the bigger one.我想没必要买较大的那个。
我们通常在think, suppose, expect, imagine等表示心理活动的动词后面不加否定含义的宾语从句。如果后面的从句使一个否定句，我们常常将从句谓语动词的否定是转移到主句的谓语动词之前。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对我们来说就够大的了。
句子中的enough可以是形容词，也可以是副词。通常我们将enough放在名词前面或形容词或副词的后面。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. 我们不可以在浪费更多的时间了。
这里的情态动词mustn’t表示的不是“必须不”而是“不可以；不允许”。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. 我们必须决定买哪一个。
这里的which one to buy为特殊不定式短语，在句子中做decide的宾语。特殊不定式的构成形式为“关系代词或关系副词+动词不定式”。常用的关系代词有：what, which, who, whether等；常用的关系副词有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，中国民航办公室前等着购票的人们排成长长的队列。
这里的waiting是一个现在分词，在句子中做people的定语，放在名词后，相当于一个定语从句。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，在中国乘飞机旅行的人数比以往多了。
这句话中的as a result的作用相当于一个副词，意思相当于so。比如：
He hurt himself. As a result, he couldn’t go to school.
这句话中的the number of 的中心词是number，说明谓语动词肯定是单数的。比如：
The number of the books in this bookshop is more than 200,000.
20. 我们在很多句子中都用一个代词来代替前面提到的名词，常见的有one, it和that。这三个词都是代词的时候的区别：
1, one=a/an +noun 所代表的是前面提到的同类中的任何一个
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类中的另外制定的一个.
The air of the country is purer than that of the city.
比较下面三句话：
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.

13、take up 开始从事/着手处理/接受，
14、 hardly ever 几乎不，
15、too…to…太而不能
二、习惯用法、搭配
want to do sth. 想做某事，
be going to + 动词原形：将要做某事，
practice doing sth. 练习做某事，
keep on doing sth.继续做某事，
learn to do sth. 学会做某事，
finish doing sth做完某事，
promise to do sth.答应做某事，
help sb. to do sth.帮助某人做某事，
remember to do sth. 记住要做某事，
agree to do sth.同意做某事，
love to do sth.喜欢做某事，
be going to 的用法
1） be going to + 动词原形——表示将来的打算、计划或安排。常与表示将来的tomorrow, next year等时间状语或when 引导的时间状语从句连用。各种句式变换都借助be 动词完成，be随主语有am, is, are 的变换，going to 后接动词原形。
肯定句： 主语 + be going to + 动词原形 + 其他。he is going to take the bus there.
否定句： 主语 + be not going to + 动词原形 + 其他 i’m not going to see my friends this weekend.
一般疑问句： be + 主语 + going to + 动词原形 + 其他
肯定回答： yes, 主语 + be. 否定回答： no, 主语 + be not.
are you going to see your friends this weekend? yes ,i am. / no, i’m not.
特殊疑问句： 疑问词 + be + 主语 + going to + 动词原形 + 其他？
what is he going to do this weekend? when are you going to see your friends?
2) 如果表示计划去某地，可直接用 be going to + 地点
we are going to beijing for a holiday.
3) 表示位置移动的动词，如go , come, leave 等常用进行时表示将来。
the bus is coming. my aunt is leaving for beijing next week.
4) be going to 与 will 的区别：
① 对未来事情的预测用“ will + 动词原形”表达，will 没有人称和数的变化，变否定句要在will 后面加not,
也可用will 后面加 not,或者缩略式won’t, 变一般疑问句将will 提至 句首。
will planes be large in the future? yes, they will. / no, they won’t.
②will 常表示说话人相信或希望要发生的事情，而be going to 指某事肯定发生，常表示事情很快就要发生。
i believe lucy will be a great doctor.
③ 陈述将来的某个事实用will. i will ten years old next year.
④表示现在巨大将来要做的事情用 will. i’m tired i will go to bed.
⑤ 表示意愿用will. i’ll tell you the truth.
⑥ 表示计划、打算要做的事情用 be going to, 而不用 will.
i’m going to buy a computer this month.
---let’s discuss the plan, shall we? ----not now. i ______ to an interview. a. go b. went c. am going d. was going
------jack is busy packing luggage. ---yes. he ____for america on vacation. a. leaves b. left c. is leaving d. has been away
三、重要句子（语法）
what do you want to be when you grow up? i want to be an engineer.
how are you going to do that? i’m going to study math really hard.
where are you going to work? i’m going to move to shanghai.
when are you going to start? i’m going to start when i finish high school and college.
四、词语辨析
1 promise vt. 保证，许诺。有三种结构：
1)promise to do sth. ——my mother promised to buy a piano for me.
2)promise sb. sth. ——my aunt promised me a bike.
3)promise + that 从句——tom promises that he can return on time.
promise n. 允诺， 诺言 lily is a dishonest girl. she never keeps a promise.
2.when 与 while 的区别：
when 表示“当…时候”，既指时间点，又指一段时间，when 引导的时间状语从句中的动词可以是终止性的也可以是延续性的。when the teacher came in, the students were talking.
when she arrives, i’ll call you.
while 表示“当…时候”，仅指一段时间，从句中的动作必须是延续性的，一般强调主从句的动作同时发生， while 还可以作并列连词，意为“ 而、却”，表示对比关系。
lisa was singing while her mother was playing piano.
tom is strong while his younger brother is week.
3. practice vt. 练习， 后接名词，代词或v-ing 作宾语。
your elder sister is practicing the guitar in the room.
常跟v-ing 作宾语的动词有：
考虑建议盼原谅：consider, suggest/advise, look forward to, excuse, pardon.
承认推迟没得想： admit, delay/put off, fancy.
避免错过继续练：avoid, miss, keep/keep on, practice.
否认完成能欣赏： deny, finish, enjoy, appreciate.

一、阅读理解
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?（ ）
a. to think clearly, to do homework and to write.
b. to play games, to do math and to copy.
c. to think clearly, to get information and to use it well.
d. to count, to clean the house and to get information.
4. does the writer think computer is a good thing?（ ）
a. it isn’t mentioned. b. no, he doesn’t think so. c. he doesn’t know. d. yes, he does.
设计目的：进一步加强对基础知识的巩固，并利用话题作文，来引导学生正确的使用电脑，并从中受益。让学生远离网络的不良伤害，建立正确的上网意识。利用与电脑有关的阅读理解来进一步开拓学生的视野，接触与之有关的知识。
八、课后反思

Computer 篇13
动词时态 一、经过前几个单元的学习，到这个单元为止，时态已经学完。按照要求，学生需要掌握下列几个重要时态。 1、一般现在时。 1》概念 其基本意义在于表示发生在包括讲话时间在内的动作或状态。 2》理解：本时态主要关注动作的经常性，强调动作表现的事实，或者是真理，而且和现在有关。 〈1〉表示客观真理，科学事实，格言，及其它各种不受时间限制的客观存在状况。 如： light travels faster than sound action speaks louder than words <2> 表示经常性或习惯性的动作。 如；our art teacher practises painting twice a day. tom often regularly drop in on the professor. <3> 表示现在的特征或状态。 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等引导的时间，条件，或让步壮语从句中，常用一般现在时。 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> 在新闻标题，小说，戏剧，电影，图片等说明中，也经常用一般现在时。 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》标志：often/always/usually/seldom./never..对上述壮语提问时，常用 how often...? 肯定句中，动词用第三人称单数形式。 如: ---how often does he visit the old man? —---never. 2.一般过去时 1》概念 本时态主要是表示过去的时间内发生的动词作或者是状态。 2》理解 强调过去动作的一次性和习惯性。 <1> 表示过去特定时间的一次完成的动作。 如： the old professor stepped into the classroom, opened the book, and began to read. we went to beijing and visited heaven temple. <2> 用它表示习惯性动作，往往用一定的时间状语或表示频度的状语。 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. 在日常会话中，我们也用一般过去时表示现在的时间。这种用法在讲话的口气上表现出婉转，客气的意味。 如： ---did you want me ? ----yes,i hoped you could give me a hand with the painting. 3》警示：除了表示明显的过去时间状语外，还有used to/would等暗示性词语。 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。这两个词虽然都表示"过去常常",但would 常和时间连用，如 often, every day 等，而used to 不可以。 3。一般将来时 1》概念 表示将来要发生的动作。 2》理解 对未来事情的预见性，或者说明意图，打算。 <1> 用will 或shall +动词的形式表示对未来事情的预见性，又称为预见性将来时。 如： tomorrow will be fine . you will feel better after taking the medicine. <2> 用 be going to do表示将来。 用这种形式表示将来主要是说明现在的意图，打算，即表明眼前最近要去做的事情。又称之为近期将来。如：i'm going to post two letters after class./she is going to have a university degree. 如果这种结构用物做主语，也是一种预见，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 表示将来 一般说来，用现在进行时表示将来所用的时间大都是动作动词，不适用于状态动词。用这种结构表示按计划要去做的事或发生的事情。 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 一般来说，be doing / be going to do 两种结构均可以表示将来，但有些区别。 比较：i am taking mary out for dinner tonight . i am going to take mary out for dinner tonight. 第一句表示计划已定不能改变，第二句表示打算未定只是一种想法而已。 <4> 用be+to do 表示将来时间 这种结构也可以表示按计划，随安排将要去做的事情或将要发生的动作。 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. 这种结构表示的将要发生的动作一般来说受人们意志控制或支配的。可以互换，但语意上有区别。如： we are going to play basketball this afternoon.<表示目前的意图> we are to play basketball this afternoon.<表示计划，安排或受人的支配>. 我们可以说：it's going to rain /the young man is going to be fat. 但不能说：it is to rain/the young man is to be fat. <5>用一般现在时表示将来。 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/ 表将来。 如：the meeting is about to begin. we are on the point of going out ... 但值得注意的是这种形式不和将来的时间用在一起。我们不可以说they are about to leave this afternoon. 4。进行时 1》概念 表示某时某刻某阶段正在进行的动作。 2》理解 进行的动作包括现在，过去和将来。 <一> 现在进行时 本结构是am/is/are+doing构成的形式。这种时态表示的动作主要与现在时间有关系。有如下的用法。 <1> 表示此刻正在进行或发生的动作 常伴有时间状语。如：now/at present/ at the moment at present, the staff are holding a meeting. where are they having the basketball match ? <2> 表示现阶段正在进行的动作。 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> 如果和表示频度的时间状语连用，不表示动作的进行，而表示动作的重复性，在语意上带有感情色彩。如： you are continually finding fault with me.<表不满》 he is always thinking of how he could do for the people《表赞扬〉 the old man is constantly complaining of his watch being slow.〈发牢骚〉 〈二〉过去进行时。 本结构是was/were+doing 构成的形式。它表示的状态或动作主要和过去的时间有联系，所以往往和表示过去的时间连用。 〈1〉表示过去某时刻正在进行的动作。如： what were you doing at ten last night? when i got up this morning, it was raining outside. <2> 表示过去某阶段中正在进行的动作。如： at that time, he was working in a pla unit. in those years he was having a happy life. <3> 在叙述故事的背景时，为了使故事的语言更加生动，让读者有身临其境的效果，多用进行时。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... 正如现在进行时一样，过去进行时与表示频度的时间状语连用，也能表示某种情感色彩。 3》警示 进行时还常用在语境中，表示语气的委婉。如： ---what are you going to do? ---i'm hoping to invite you to dinner. 5.完成时。 1》概念 本时态是表示某动作或某过程在一定时间内处于完成的状态。 2》理解 完成时包括现在完成时和过去完成时态。构成分别为have<has> done/had done. <一>现在完成时。动作在过去发生，持续到现在已经完成，或者是继续持续下去。 <1> 已经完成的用法。其表明某动作或过程发生在说话前某个不明确的过去时刻，到目前一完成，并对目前造成影响。如：he has not been to shanghai/have you finished reading the story ? 本用法常和不确定时间状语连用。如：already/yet/before/recently/lately/just...等 i have seen him before we haven't been there lately 也可以和表示频度的时间状语用在一起。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。本用法表示某动作或状态开始于过去某个时刻一直延续到现在，而且还要继续下去，在某种情况下也可能刚刚结束。常和 since/for/时间状语连用。如： he has been in the army for 3 years. he has lived in the building since he came here. 3》警示：如果不过since 引导的从句中的动词是延续性的，一般认为，语意上也表明动作或状态的结束。如： i haven't heard from him since he lived there. 从他离开那儿以来，我一直未收到他的消息。 he has written to me frequently since i was ill. 从我病愈以来，他常给我写信。 如果since引导的从句中的谓语动词用了现在完成时，那么表示的动作或状态就不表示完结。如： i haven't heard from him since he has lived there . 从我住在那里以来，我一直未收到他的来信。 he has written to me frequently since i have been ill. 从我生病以来，他常给我写信。 <二>过去完成时。本时态表示的是动作在过去的过去发生。它也分为“已完成用法”和“未完成用法”。 1>已完成用法。表示，当一个动作发生或结束时，在它之前的另一动作已经完成。这种用法既用于动作动词，也用于状态动词。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。表明某个动作或状态在过去某个时刻之前一直延续到过去这个时间，而且还可能继续下去。它也使用于动作和状态动词。而且常和 by +过去时间 或从句 连用。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 + 过去时间或从句的结构中，如果主句动词是动作动词，用过去完成时，如果是状态动词，用一般过去时。比较： 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，主句用过去完成时，从句用一般过去时。而且，如果hardly./no sooner 提前，主句需要部分倒装。如： i had hardly recoganized him when i saw him. hardly had i recoganized him when i saw him.
