Unit 9 教學步驟

　PERIOD 1

Ⅰ．TEACHING AIMS

1．To train the Students' ability of listening understanding and improve their oral English.

2．To learn how to make decisions and how to agree or disagree with other people.

3．To learn to use the following useful words and expressions.

improve although believe complete information go up

bring down　 at one time make a plan for　 thanks to keep a record

Ⅱ．TEACHING STEPS

Step 1 　Make clear the teaching aims

Tell the Ss that in this period we are going to learn how to use different structures for making decisions.

Step 2 　Presentation

1．Ask the following questions.

Have you ever seen/used a computer?

How often do you have your computer class?

Do you have a computer in your home?

What type of computer do you use in your computer class?

2．Tell the Ss that we are going to learn a dialogue.

In the dialogue Jenny and MeiGe are talking about buying a computer.

T: Please listen to the tape carefully with your books closed. While listening, try to find the answer to this question.

Which computer did they decide to buy?

(They haven't made a decision yet.)

Step 3 　Drills

1．Get the Ss to listen to the tape again.

T: We are going to listen to the dialogue again. While listening, collect the information about the two different types of computer. You may need to take brief notes.

IBM PC 386:smaller;may need to change it in a few years' time.

IBM PC 586:bigger; more expensive; may be too big.

(If the teacher feels necessary, he or she may explain the following items now.)

IBM: International Business Machine Corporation

PC: Personal computer

2．Get the Ss to follow the tape this time to tell them to pay attention to the pronunciation.

3．Get the Ss to read the dialogue in pairs or groups. Allow them enough time to discuss any difficult sentences so as to understand the dialogue fully. If they still have problems after the discussion, they may ask the teacher to explain them.

4．Possible problems

1)Did you find out the price for the IBM PC 386?

(The students may ask why the phrase find out instead of find is used here.)

Teacher's explanation:“find”means discover someone or something after looking or simply by chance; while “find out” means learn something by asking or studying.

2)We might have to change it in a few years' time for a bigger one.

Teacher's explanation: Maybe several years later we will have to sell the old computer and buy a bigger one instead.“Might”is used here to suggest a kind

of future possibility and it's also a very polite way of showing one's different opinion.

3) We must decide which to buy.

We must decide which computer we are going to buy.

The teacher may explain that“whwords +to do”are often used as object and predicative. Some more examples may be given if the teacher feels necessary.

You can learn how to type here.

She considered how to answer the question.

The problem is where to find him.

Step 4 　Practice

1．Tell the Ss that there are several useful words and

expressions in the dialogue.

The teacher may explain the following so that the students may get a better understanding of both meaning and the usage of them.

information: news; facts; what you tell someone

(Let the students notice that this word is uncountable. Similar words are news, advice, progress, development, etc.)

necessary: important; that you need.

go up: become higher in price. This phrase is also used to describe the rising of the water(in a river).(Notice that this phrase is intransitive, while bring down is transitive, which always needs an object.)

improve: become better; make someone or something become better.

“Improve”is a very important word. Listen to the following sentences and translate them into Chinese.

1）You must improve your writing.

2）It will help to improve your speaking.

3）The old man went to night school to improve himself.

4）The living conditions of the laid off workers need to be improved.

5）Everyone considered it greatly improved.

6）After tea his spirits improved and he went round for a walk.

7）I feel certain that things will greatly improve with you in a month or so.

8）His reading reading is improving.

9）He's improving in health.

Ask the students to sum up how the word “improve ”is used in the above sentences. Tell them that when used as an intransitive verb, it means to become better; when used as a transitive verb, it means to make someone or something become better.

2．Get the Ss to review the usage of each of the words and expressions and them write the structures on the Bb.(see WBb 1)

Allow the Ss several minutes to make sentences with the words and expressions on the Bb. Tell them to try to make as many sentences as they can. Top students are encouraged to make a short story using some of the words phrases.

2．Let some Ss speak out so that the others can hear their sentences clearly. Praise them if they've made good sentences.

Get the Ss to read the dialogue again to find out the expressions on making decisions. Write them on the Bb.(See WBb 2)

Step 5 　Summary and further practice

1．Summary

Go over the useful expressions and structures on the Bb again and make sure they've learnt how to use them.

2．Communicative activities

Allow the Ss enough time to make a similar dialogue using the expressions and structures on the Bb. The students can refer to the phrases in Part Two. Now it's a good chance to introduce more items which are often used when people agree or disagree with other people.

1)How to agree strongly with an opinion.

I can't agree more!/Absolutely!

I'm with you on that ./That's just what I was thinking.

That's exactly what I think/my opinion.

2）How to half agree with an opinion. Yes, perhaps.

Well, yes.

Mmm, possibly.

I guess you could be right.

That's something in that, I suppose.

That's worth thinking about.

3）How to disagree politely with an opinion. I am not so sure really.

Do you think so?

Well,it depends.

I'm not so certain.

Well, I don't know.

4）How to disagree strongly with an opinion. I disagree.

I'm afraid I don't agree.

I'm afraid you are wrong there.

I really can't agree.You can't be serious.

You must be joking.

The following topics are for the Ss to choose from, or they may just talk about their own topics. The students can to use the above items in their dialogues.

Step 4 　Reading comprehension

1．Allow the students enough time to read the passage.

Ask some students which they think is the best title of the passage and also ask them to give the reason why they choose it. The students are encouraged to express different opinions.

2．Explain that a best title is a highly condensed phrase(or a sentence)from which the reader can predict the article in the right way, and it should be description about the major theme of the passage; there may be lots of words describing a concrete affair, but it may be just one of the supporting examples of the major theme.

3．Ask the Ss to scan the text to find the following specific information.

1）What is the newlybought computer used to do in CAAC?

(It's used to record the tickets which passengers buy.

It also keeps a record of the date on which they will travel.)

2）In what way can the computer help people?

(With the help of the computer, people can find out much faster which planes are full and which planes still have free seats on them, and passengers at the offices of the CAAC can now buy their plane tickets much faster.)

3）What were things like in the past?

(At one time, there were long queues of people waiting outside the CAAC offices. The passengers might not be able to buy their tickets three days before their travel.)

4．How many offices does the CAAC have?

(They have 200 offices in 200 cities in China and 70 cities abroad.)

5．What has happened since the computer was bought?

(Travellers and business people both at home and abroad have been greatly helped by this new computer. As a result, the number of people who travel by plane in China is larger than ever before.)

Step 5 　Practice

1 ．Ask the Ss to read aloud the text to understand each sentence. Explain the difficult sentences if there are any. Possible problems.

1）free seats: seats which are not booked or taken(Some students may take it as seats which cost nothing.)

2）at home and abroad:(here)in and out of China

3）thanks to: because of

4）You might not be able to…traveled: here“might”refers to past possibility.

3）How widely is the computer used today? Give some examples.
