III. 教材分析與教材重組
1. 教材分析
本單元的主題是Technology，中心話題為Hi-tech,話題本身具有強(qiáng)烈的時(shí)代氣息，貼近學(xué)生的實(shí)際生活，符合學(xué)生的認(rèn)知水平，在學(xué)生中有較強(qiáng)的認(rèn)同感。
1.1 WARMING UP 提供了三種智力小測(cè)試，借此誘發(fā)學(xué)生的想象力、判斷力、創(chuàng)造力和逆向思維能力，為下文作好鋪墊。
1.2 LISTENING的第一部分是聽三段描述日常用品的語(yǔ)言材料，旨在培養(yǎng)學(xué)生捕獲相關(guān)物品特征、用途等關(guān)鍵詞的能力；第二部分是第一部分的延伸，進(jìn)一步引導(dǎo)學(xué)生掌握描述物品特征的詞匯和技巧，達(dá)到創(chuàng)造性運(yùn)用語(yǔ)言的目的。
1.3 SPEAKING 部分根據(jù)材料要求，把全班分成四個(gè)小組，每一組從不同角度出發(fā)討論購(gòu)買手機(jī)和不買手機(jī)的理由。既引導(dǎo)學(xué)生合作學(xué)習(xí)，又培養(yǎng)學(xué)生全面地、辯證地看待問題的哲學(xué)觀和消費(fèi)觀。
1.4 PRE-READING是READING的熱身活動(dòng)。要求學(xué)生采用討論交流的方式談?wù)摤F(xiàn)代科技對(duì)人們?nèi)粘Ｉ畹挠绊�，激發(fā)他們對(duì)閱讀主題文章的欲望。
1.5 READING一文采用前后呼應(yīng)的寫作手法，介紹手機(jī)的用途、所產(chǎn)生的問題并剖析年輕人寵愛手機(jī)的原因。文章選材新穎，貼近現(xiàn)實(shí)生活，主題鮮明，容易引起學(xué)生的閱讀興趣和共鳴。
1.6 POST-READING從回答問題、概括段落大意和創(chuàng)造性設(shè)計(jì)三個(gè)層面逐步推進(jìn)，激勵(lì)學(xué)生結(jié)合現(xiàn)實(shí)生活，開動(dòng)腦筋，充分發(fā)揮想象力和創(chuàng)造力設(shè)計(jì)自己的產(chǎn)品，從而達(dá)到運(yùn)用英語(yǔ)進(jìn)行交際的能力。
1.7 LANGUAGE STUDY 的“詞匯學(xué)習(xí)”目的在于培養(yǎng)學(xué)生根據(jù)語(yǔ)境掌握并運(yùn)用所學(xué)詞匯的能力。“同步語(yǔ)法”則設(shè)計(jì)了不同類型的句型轉(zhuǎn)換題，旨在訓(xùn)練學(xué)生準(zhǔn)確理解和靈活運(yùn)用現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)的能力。
1.8 INTEGRATING SKILLS中的閱讀部分是一篇科幻文章，大膽想象未來世界受電腦統(tǒng)治的情景，引導(dǎo)學(xué)生思考未來科技對(duì)人類生產(chǎn)、生活的影響。相對(duì)起來，寫作任務(wù)更加富有挑戰(zhàn)性，不但需要學(xué)生大膽想象，還需要短文具有較強(qiáng)的說服力和思辯性，最后點(diǎn)明“愛”和“友誼”這一文章主題。
1.9 TIPS 部分給出指導(dǎo)學(xué)生進(jìn)行有效閱讀的技巧--根據(jù)上下文猜測(cè)詞義。
1.10 CHECKPOINT“復(fù)習(xí)要點(diǎn)”部分簡(jiǎn)要地總結(jié)本單元語(yǔ)法重點(diǎn)，并引導(dǎo)學(xué)生學(xué)會(huì)總結(jié)知識(shí)要點(diǎn)。
2. 教材重組
2.1 從話題內(nèi)容上分析，WARMING UP 與SPEAK-
ING相一致；而從訓(xùn)練目的上分析與TALKING比較一致。從教材份量來說，可將WARMING UP，SPEAKING和Workbook中的TALKING整合在一起，設(shè)計(jì)成一節(jié)任務(wù)型“口語(yǔ)課”。
2.2 將LISTENING 和Workbook中的LISTENING整合在一起，設(shè)計(jì)成一節(jié)“聽力課”。
2.3 可將PRE-READING, READING和POST-READING三個(gè)教學(xué)活動(dòng)整合在一起上一節(jié)“閱讀課（一）”。
2.4 可將LANGUAGE STUDY 與Workbook中的PRACTISING語(yǔ)法練習(xí)題整合在一起上一節(jié)“語(yǔ)法課”。
2.5 可將INTEGRATING SKILLS 中Reading和Workbook中INTEGRATING SKILLS的Reading整合起來上一節(jié)“閱讀課（二）（泛讀課）”。
2.6 將INTEGRATING SKILLS 中的Writing和Workbook中INTEGRATING SKILLS 的Writing整合成一節(jié)“寫作課”。
3. 課型設(shè)計(jì)與課時(shí)分配（經(jīng)教材分析，根據(jù)學(xué)情，本單元可以用六課時(shí)教完）
1st period 口語(yǔ)課

Teaching procedures && ways 教學(xué)過程與方式
Step I Greetings
T: Good morning/afternoon, boys and girls! We all know that science and technology are very important in our daily life. Can you give some examples?
S1: I think the computer is a very good example. It is widely used in many fields. If we want to read the latest news or look up information, we can go to the Internet.
S2: In our classroom we also use a multi-media computer, a projector and a colour TV set. Some students even have cellphones.
T: Well done. Let’s come to WARMING-UP.
Step II Warming up
1. Useful things
This step is designed to introduce the topic and arouse the students’ interest in creative ideas.
T: I find all of you are very clever and hardworking. But are you really creative? Here are some tests. Here I have three useful things (The teacher shows toothpicks, a pair
of socks and a plastic bag). Do you know their common use in our daily life?
S3: Toothpicks are often used to get bits of food out of the space between teeth.
S4: Socks are usually worn to keep us warm.
S5: Plastic bags are often used to put things in.
T: Quite right. Now you are divided into three (or more) groups. Each group talks about one subject. (After a few minutes) Now time is up. Volunteers.
S6: Toothpicks have many new uses. For example, we can use toothpicks to pick small things, pin some food, get little bits of food between the teeth, make fine designs...
S7: A sock can also be used in many ways, like polishing shoes, decorating a doll, filling something in...
S8: Maybe a plastic bag can be used most. It can be used to protect the seatbelt from rain, touch some dirty things, carry vegetables...
2. Talk box
Task 1 Making new words
This task aims at finding out how creative the students are in observing and understanding.
T: Now let’s come to a talk box. Here you can move any side as many steps as you wish so that you can create many different words.
Steps: 1. Divide the students into several groups (4-8);
2. Individual work. (Each student tries to think of more possible answers.)
3. Group work. (Get one student to summarize their answers.)
4. Class competition. (If one group gives the largest number of answers, it will win.)
Possible answers:
S9: scar, door, rate, date, item, stop ...
S10: soar, side, star, coat, poem, code ...
S11: road, mood, mead ...
S12: rats, eats ...
3. True or false
T: Well done! Now here are three sentences. Please read carefully and decide if they are true or false. Then give your reasons. (After a few minutes) Now who’d like to
have a try?
S13: The first sentence is true. We can easily find four letters “b-o-a-t”, which is the word “boat”.
S14: The second sentence is false. 12 minutes past 5 o’clock is 48 minutes before 6 o’clock.
S15: The third sentence is true. (The teacher gives him or her a left-handed glove to have a try.)
Step III Speaking
T: In our everyday life we may meet with some trouble. What shall we do? Yes, we can turn to our parents or best friends for help. Now Jane wants to buy a cellphone.
Before she buys one, she asks her parents and her best friend what they think.
Task 2 Role-play the discussion
This part is to provide the students realistic situations so that they can have more chances to practise the functional items.
Steps: 1. Divide the students into four groups. (“Jane” will be the leader.)
2. Individual work. (Each tries to think of more answers to support his/her opinion.)
3. Group work. (Each member states his or her opinion and reasons.)
4. Class work. (Jane chairs the discussion.)
One possible discussion:
Jane: Dad, Mum and Lily, I’m glad to take this chance to have a discussion. You know, I am always eager to have my own phone, but I still haven’t got it. Here I’d like to share you with my opinions. At the same time, I’d like YOUR advice.
Lily: Good idea. Why not give your reasons first?
Jane: Thank you. In my opinion, with a cellphone, I can call my friends for help when in trouble. I can also let you know where I’m. What’s more, I can send short
messages to my faraway friends instead of writing letters. In this way I can save some time and money as well.
Mr Evens: I agree with you, Jane. Besides keeping in touch with us, you can also learn about the latest news both at home and abroad. Sometimes you can even call your teacher or classmates for help while doing homework.
Lily: Well, Mr Evens, that may be true, but I don’t quite agree with you. You know, we are still middle school students, not adults. On one hand, we are not allowed to use cellphones in school. On the other hand, buying and using a cellphone will cost a lot of money. Worse still, cellphones are changing so quickly that they can be easily out of fashion.
Mrs Evens: You’re right, Lily. I don’t think cellphones will do any good to your studies. Besides, you may receive some waste short messages.
Jane: Thank you for telling me what you are thinking. It’s likely that I will think about your opinions and then make the final decision. Thank you, bye.
Possible reasons for discussion:
1. Jane:
1. I can ask my friends for help.
2. I can let my parents know where I am.
3. I can send short messages to save time and money.
2. Jane’s mother: Mrs Evens
1. Cellphones cost too much.
2. It will be bad for her study.
3. She may receive some waste short messages.
3. Jane’s father: Mr Evens
1. He can keep in touch with her.
2. She can learn about the latest news.
3. She can make her work or study easier.
Step IV Talking (See P134)
This part should be a free talk concerning the two sides of modern technology: advantages and disadvantages. The teacher may give the students some help if necessary.
T: Now let’s come to Talking on Page 134. As we know, modern technology is playing a more and more important part in our life. It helps us do many things we want to do, but technology also causes problems. Then what are the advantages and disadvantages of modern technology? You are given several minutes to write down your answers. Then tell your partners your opinions and give your reasons. (After a few minutes)
S16: I think cellphones have many advantages. We can keep in touch with our family or friends wherever we are. Sometimes we can send message, music or images to our friends. We can even surf the Internet for latest news or information. Besides, if you have the latest model, it can make you look nice in front of your friends. Your mobile phone is like a status symbol-it says you are cool or not.
S17: I’m afraid I don’t agree. First, buying a cellphone will cost a lot of money. Second, it will take you much time and money to make phone calls. Third, if you use too much, it will surely disturb your work or study. Finally, it’s reported that if you use mobile phones for a long time you are at risk of developing cancer.
T: Excellent. Now your opinions about robots?
S18: In my opinion, robots have quite a few advantages. They are machines controlled by computers. They can work for a long time without sleep or rest. More important, they can do some work repeatedly and efficiently. They can often be seen in dirty or dangerous areas. In a word, robots are very useful both in daily life and in industries.
S19: Well, that may be what you were thinking. In fact, robots are advanced products and they are very expensive to buy and repair. They can’t think or make decisions. If robots are widely used in factories, then many workers will be out of work. I don’t think it a good thing.
T: Well done. Maybe you also want to express yourself concerning computers.
S20: Quite right, sir. I’d like to say computers can help us most in our daily life and they have far more advantages. With a computer we can work out complicated problems, store information, manage a company and surf the Internet. Without computers we can hardly imagine what our life would be like. In fact computers are being widely used in education, industry, agriculture, space, medicine and so on. They can be seen almost everywhere.
S21: As we all know, buying a computer will cost a lot of money. At the same time, it’s not very easy to learn how to operate a computer, especially for some aged people. At present we can often hear about computer viruses, which will make the computers fail to work normally.
T: I’m glad to you have performed so well. Just as the saying goes, every coin has two sides. What we can do is make the best use of the great inventions mentioned above, isn’t it?
Step Ⅴ Language points
1. That’s worth thinking about.
“be worth doing” is a useful set phrase. We can also say “be worth + money”.
e.g. The film Harry Porter is so wonderful that it is worth seeing a second time.
The new MP3 is worth 400 yuan.
2. Well, it depends.
“It/This depends” is also a set phrase which means
“It is hard to say or decide”. Here is another useful phrase “depend on/upon” which means “rely on”.
e.g. -Will you go to the park this Sunday afternoon?
-Well, it depends.
All living things depend on the sun for growth.
Step VI Homework
1. Consolidation
T: Today we have learned so much about how to express our opinions. I do hope you can practise more after class.
2. Discussion
Middle school students should go online in their spare time or not. Please discuss this topic and give your opinions.
