Ability goals 能力目标 ‎ Enable students to learn about the development and history of computers. ‎ ‎3. Learning ability goals 学能目标 ‎ By finishing the timeline and the chart, help students grasp the basic structure and main idea of the passage. ‎ Teaching important and difficult points 教学重难点 Understand how details are used to support topic sentences. ‎ Teaching methods 教学方法 Prediction, scanning and discussion. ‎ Teaching aids 教具准备 Projector and tape recorder.‎ Teaching procedures & ways 教学过程与方式 Step I Warming-up T: How many of you have computers in your home? Please put up your hands.‎ Ss respond accordingly. ‎ T: What do you usually do on your computers?‎ Ss: Type documents/homework, listen to music, watch videos, play games, search on the Internet, send mails …‎ T: When I were at your age, I knew nothing about computers. Most Chinese families never heard about it. However, in recent years, computers have become more and more popular, and most families in cities have one or more than one computer in their home. And some families in villages also have their own computers.‎ ‎ Computers make life more convenient and colorful. However, it took a long time for humans to have computers that we see today. Now look at the pictures on page 17 and discuss what they have in common. Then think about Questions 2 & 3.‎ Suggested answers:‎ 1. These pictures are all technological inventions.‎ 2. From these pictures, we know computers have experienced a long development process, and the development will never stop.‎ 3. ‎(There may be various answers.)‎ Step II Pre-reading Prediction Let students predict the content of the passage according to the pictures and the title. This will involve students in active thinking and exploring. ‎ Then let them make a list of the ways computers are used today. ‎ Sample list:‎ date processing industrial design learning and teaching aids TV program editing ‎ entertainment (watch TV/video, listen to music, play games, online chat…)‎ communication (e-mail, e-card, instant message) ‎ ‎…‎ T: Now look at the inventions in activity 3. First check their meanings in your dictionaries. Then put them in the order according to the time when they appeared. ‎ Help students understand the meanings of the words: analytical, calculate and ‎ universal. ‎ Note:‎ Universal machine is also known as Alan Turing's “universal computing machine”, is ‎ capable of computing any algorithm.‎ Students may have different answers. They will check it after reading the passage. ‎ T: Have you put them in the right order? You will find it after reading the passage. ‎ Now turn to page 18 please. ‎ Step III Reading ‎ Skimming Get students read the whole passage and try to get the main idea of it.‎ After reading T: What does “I” in the title refer to?‎ Ss: Computer.‎ T: What is the main idea of the passage?‎ Ss: The passage is mainly about the history and development of computers. ‎ Scanning T: Correct! Now read the passage and finish the timeline. With this timeline, you will have a clear idea of the development of computer. ‎ Check the answers. ‎ T: The passage has three paragraphs. Find out the topic sentence of each paragraph, and the details that are used to support the topic sentences. Then complete the chart in activity 2. ‎ Suggested answers:‎ Para. 1‎ Para. 2‎ Para. 3‎ Topic sentence Over time I have changed quite a lot.‎ These changes only became possible as my memory improved. ‎ Since the 1970s many new applications have been found for me.‎ Supporting details l Caculating machine l Analytical machine l Universal l Tubes l Transistors l Chips l Network l Web l Communication l Finance l Trade l Robots l Mobile phones ‎ machine l PC l Laptop ‎ l Medical operations l Space rockets T: From this chart, you will know the basic structure of this passage. As you may have found the topic sentences are not standing there alone, they are supported with details and date, which make the topic sentences more convincing. Now I will play the tape of this passage. Listen and find out/underline the difficult words and expressions. ‎ Teacher gives some explanations. ‎ T: What can be “over time” replaced by?‎ Ss: As time goes by.‎ T: How do you understand the word “simplify”? Look! (on the board: simple+-ify). -ify is a suffix which means to turn into, make or become. For example, beautify. So if you know the meaning of “simple”, you can easily get the meaning of “simplify”. Who can tell me its meaning?‎ S: To make something easier or less complicated. ‎ T: What does “it” in line 9 refer to? ‎ Ss: It refers to the fact that computer was programmed by an operator who used cards with holes.‎ T: Why was Alan Turing called computer’s real father? ‎ S: I guess that’s because Alan made computer more powerful, which could solve any difficult mathematical problem. ‎ T: What does “this reality” in line 15 refer to?‎ S: It refers to the reality that computer had grown as large as a room. ‎ T: In paragraph two, there are two sentences which contain the use of “so…that…” structure. Underline them and study carefully.‎ Show the following on the screen/board:‎ l Over time my memory has developed so much that, like an elephant, I never forget anything I have been told!‎ l And my memory became so large that even I couldn’t believe it! ‎ Help students sum up the form and function of this structure:‎ Form: so + adj./adv. + that + clause ‎ Function: This structure is used when emphasizing the degree or amount of something by saying what the result is. ‎ Step IV Discussion Deal with activity 3 on page 19. Let students discuss how computers have changed ‎ our lives? ‎ Sample discussion:‎ S1: I think it’s impossible to live without computers!‎ S2: What makes you say that? My grandparents didn’t use a computer and they were still able to entertain themselves, to operate big machines, to analyze data, to make robots and so on. ‎ S1: You are right. But computers do change the way we live. They change the way we learn by providing distance-learning programs. They change the way we communicate with the use of e-mail and instant messenger. They change the way we obtain information with Internet search engine such as Google and Baidu. They change the way we deal with documents and pictures. ‎ S2: I agree. Can you imagine what our life would be like If we could not use computers any more?‎ S2: We would go back to the world when everything goes slowly. For example, send mails via train or air plane, which takes several days or even long; go to libraries to search for information, where limited information are provided; spend long time to solve difficult mathematical problems etc. And on the other hand, we may have more time for outdoor activities instead of spending much time on computer. ‎ S1: Yes, computers changed our lives both in a good way and in a bad way. It depends on how we make use of it. I hope we can make good use if it. ‎ T: Do you want to see how cyber friends answer this question? Look at the screen.‎ Show the following on the screen or let students visit the web page: ‎ ‎(One the screen)‎ User 1 ‎ Computers have made it easier for us to access a wealth of information and have all but rendered printer encyclopedias obsolete. They have also made it easier and cheaper to advertise our business anywhere we wish and do business with anyone anywhere in the world. On the downside however, computers have also made it easier for sexual predators to find victims, for criminals to steal our hard-earned money, and to even steal our identity, something nearly unheard of just a few decades ago. Also, children are more likely to sit in front of a computer and chat when they could just as easily speak with their friends on a telephone or go outside and play like children used to before the "computer revolution". As with any new technology, there are good and bad points, but in the end the general public through their actions will determine whether or not computers have actually improved our lives. ‎ User 2 ‎ Of course!!!!! They have changed the way we shop, play, chat, work and more.‎ User 3 ‎ They have made us a lazy generation.‎ User 4 ‎ A computer has changed my life certainly even still at a very young age. It's fulfilled my dreams, knowledge and much more. For some it's gained them employment and giving others something to do. It's opened a new world of gaming, chatting and finding advice and information. I COULDN'T LIVE WITHOUT ONE! ‎ User 5‎ Well, they made our lives easier, the made us lazier and they gave us the chance to ‎ have some adventure when we are bored.‎ User 6 ‎ Majority of "addicted" computer users lack "real life" social skills these days.‎ User 7‎ They hurt my eyes.‎ User 8 ‎ Computers change our attitudes, the way we live, the way we express ourselves, the ‎ way we are too others, views on life, views overall, how we dress, what we listen too, what we think of one another, how we work, interests. Basically everything without computers we wouldn’t have the internet and like newspapers radios magazines and television we get these all on the internet. These change how we are so basically everything about it. Also we get addicted and learn about things that maybe we shouldn’t. Also can get into trouble e.g. downloading, piracy all done with a computer. Good things are that computers have helped reach forward into the future. ‎ Helps with technology, education and will help the future generations. Soon everything will be run by computers the good thing for us is we don’t have to lift a finger the bad thing is will computers take over.‎ Step V Homework (retelling)‎ T: Suppose you work for an information technology magazine. Write a short passage which briefly introduces the history and development of computers. Don’t write in the first person. ‎ The Second Period Language study Teaching goals 教学目标 ‎1.

Ask two students to read the passage they have written. Their passage should be brief and include the key information or facts about the development of computers. ‎ Step II Discovering useful words and expressions T: Look at activity 1. These are the meanings of some words or expressions in the text we learned yesterday. Find out these words or expressions. ‎ Check the answers. ‎ T: Now look at the words in activity 2. Do you know their meanings? Check their meanings in your dictionaries. Then complete the passage with the words. ‎ Check the answers. ‎ T: Now activity 3. Look at the phrases in bold in the story. What do they have in common?‎ S: They are all time phrases except “as a result”. They are used in the passage to indicate the development of the story. From them, we get a clear timeline of the ‎ story.‎ T: Correct! Now use these phrases to create one of your own stories. The story can be a real one or an imaginary one. ‎ After they finish writing, let students exchange their stories and proofread for each ‎ other. ‎ Step III Discovering useful structures ‎ Let students find sentences in the present perfect passive voice in the text and then ‎ analyze their form and function. (Activity 1 on page 21.)‎ Students may find the following sentences:‎ ‎1. I have been used in offices and homes since the 1970s. ‎ ‎2. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told!‎ ‎3. Since the 1970s many new applications have been found for me. ‎ ‎4. I have also been put into robots and used to make mobile phones as well as help with medical operations. ‎ ‎5. I have even been put into space rockets and sent to explore the Moon and Mars. ‎ Then let students study these sentences carefully and sum up the form of present ‎ perfect passive voice tense.‎ Elicit the structure: S + have/has + been + V-ed T: Why is the passive voice used here? When do we usually use passive voice?‎ Ss: …‎ T: The passive voice is used when the subject of a sentence is the person or thing affected by the action of the sentence. We particular use the passive voice when don’t know or aren’t bothered exactly who has done something. Now look at activity 2. Change the sentences into the present perfect passive voice. Pay attention to the use of has/have. When do we use has and when do we use have?‎ Ss: We use has when the recipient of the action is the third person single or single nouns. We use have when the recipient of the action is the first or second person or plural nouns. ‎ After students finish, check the answers. ‎ T: Now write passive sentences in Present Perfect according to the words given.‎ Show the following on the screen.‎ ‎1 the postcard / send __________________________‎ ‎2 the pencils / count ___________________________‎ ‎3 the door / close _____________________________‎ ‎4 the beds / make _____________________________‎ ‎5 the mail / write _____________________________‎ ‎6 the trees / plant _____________________________‎ ‎7 the money / spend ___________________________‎ ‎8 the room / book / not _________________________‎ ‎9 the rent / pay / not ___________________________‎ ‎10 the people / inform / not _______________________‎ Answers: ‎ ‎1 The postcard has been sent. ‎ ‎2 The pencils have been counted. ‎ ‎3 The door has been closed. ‎ ‎4 The beds have been made. ‎ ‎5 The mail has been written. ‎ ‎6 The trees have been planted. ‎ ‎7 The money has been spent. ‎ ‎8 The room has not been booked. ‎ ‎9 The rent has not been paid. ‎ ‎10 The people have not been informed. ‎ Then deal with activity 3. ‎ T: Read the poem. Underline the use of the present perfect passive voice. Then decide which things have been done well and which have been done badly. Guess what might have happened to the face, hair and shoes and what might have happened to the flowers, grass and paths. You can get cues from the examples. ‎ After students finish, check their work. ‎ Then get them to write a similar poem following the rhythm and intonation. ‎ T: Which words in the poem rhymes? ‎ Ss: washed, combed, cleaned, planted, cut, swept, again, again. ‎ T: Right! Now write your own poem with similar rhythm and intonation. After you finish, exchange yours with your partner’s and check for each other. Pay attention to the rhythm and grammar. ‎ Then, let some read their poems to the class.‎ Step IV Workbook Exercises Give students some time to finish USING WORDS AND EXPRESSIONS and ‎ USING STRUCTURES in Workbook individually.

As you may have heard, it will be a century of information technology. How do you understand this frequently used term?‎ Encourage students to voice their own opinions.‎ S: I think IT is closely connected with computers. Without computers, there would be no IT. ‎ S: I guess IT refers to the computer-based information systems, which include software application and hardware.‎ S: …‎ Show the definition of IT on the screen to help students better understand this term. ‎ What is IT?‎ IT is the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware. In short, IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit and retrieve information, securely.‎ Today, the term information technology has ballooned to encompass many aspects of computing and technology, and the term is more recognizable than ever before. The information technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include:‎ · Data management · Computer networking · Database systems design · Software design · Management information systems · Systems management Step II Listening ‎ Deal with activities 1-3 on page 22. ‎ T: Excellent opinions! Now discuss in pairs what IT consists of. Make a list and compare your ideas with another pair. ‎ Give a few minutes for them to discuss and make a list.‎ T: Now you will hear a text about IT which will tell you more about it. First listen and get the main idea of the text. Write down the main idea in one sentence.‎ Play the tape for the first time.‎ Then check the sentences they write. ‎ T: What does IT include? What is the most popular form of IT? Now listen to the first part again and fill in the chart, Part A.‎ Play Part A, check the answers.‎ T: Which form of IT describes the skills of a sport best?

Which are used to make decisions?‎ Ss: The advantage/disadvantage is …‎ ‎ I think/don’t think that …‎ ‎ I believe that …‎ ‎ I’ve decided that …‎ T: Then which ask about reasons?‎ Ss: What’s your reason?‎ ‎ What makes you thinks so?‎ T: Good! Which are used to state reasons?‎ Ss: I think … because (of) …‎ ‎ I agree/don’t agree … because …‎ ‎ First … Second …‎ ‎ As/Since …, I think … ‎ T: From the listening material, we have learned about the different forms of IT such as computer, TV, book and radio. Now work in groups and discuss: What are the advantages and disadvantages of each form of IT? Use the expressions we just talked about. Then fill in the chart with your discussion results. ‎ It’s better that students work in groups of four and each focus on one form of IT.‎ Sample discussion:‎ A: I think computer is the most powerful IT form because it can store plenty of information in various forms. The advantage of computer IT is that the information can be updated at anytime and you can get almost information when connect with Internet. ‎ B: I think TV is the most popular form of IT and can be accepted by people at any age. It is easy to operate and there are more and more channels and programs to choose from. As most people still prefer to get information or have fun from TV, I think TV will continue to be a dominant IT form in the 21st century. ‎ C: I think radio has many disadvantages.‎ D: What makes you think so?‎ C: First, you can only hear but can’t watch. Second, the information that you can get from it is very limited. However, it also has its advantages. You can listen to radio programs when you are driving, walking or doing housework. What’s more, it’s small and easy to take. ‎ D: I prefer to read books. I think book is the most reliable IT form. The information in ‎ books are usually better selected and organized. Compared with TV and computer, books do less harm to eyes. You can read them again and again. While the disadvantage of book IT that it is expensive. ‎ After discussion, ask some group representatives to report their results. ‎ Step V Homework T: Chips play a very important role in computer technology. They are the “core” of computers. How much do you know about chips? After class, please find some information about it. ‎ The Fourth Period Integrating skills Teaching goals 教学目标 ‎1.

Share them with the whole class.‎ About Chips: ‎ A small piece of semiconducting material (usually silicon) on which an integrated circuit is embedded. A typical chip is less than square inches and can contain millions of electronic components (transistors). Computers consist of many chips placed on electronic boards called printed circuit boards. ‎ Computer chip technology is in all sorts of everyday items, from space shuttles to coffee makers, traffic lights, and computers. A basic rule of thumb is, if a device uses electricity and you can “tell it what to do” by programming it or customizing it, there’s a chip inside.‎ Step II Reading, speaking and writing T: The development of “chips” has brought many applications of computer technology. One of them is robots or androids. ‎ Write “robot” and “android” on the board, and explain the difference. ‎ T: Android is a robot that looks completely human. Some robots don’t look human. Now read the passage about Andy, the android. ‎ After reading, let students fill in the file or Andy in activity 1. ‎ Then check the file they filled. ‎ T: Now I’d like you to create your own android. Use your imagination and be creative. Draw a picture of it and fill in the file in activity 2. Then compare with your partner. ‎ Then get students to write a description of the android they draw. ‎ T: Before you write your own passage, read the sample one in activity 3 and tell me how the writers describes his/her android. ‎ Ss: He/she gives details about the android’s abilities and jobs. ‎ T: Right! Does he/she describe the appearance or character of the android?‎ Ss: No. ‎ T: But you can include this information in your passage. Now write your own passage according to the file you filled and the picture you drew. ‎ After they finish writing, let them read their passages to each other in groups and choose the most creative one. ‎ Step III Listening ‎ LISTENING on page 56.‎ T: Turn to page 55. Look at the pictures in activity 2.

Tell your partner one sentence about what you think you will hear.‎ Sa: We will hear about a robot design competition. ‎ Sb: We will hear a lecture on the development of robots. ‎ T: Now let’s listen and check. ‎ Play the tape. Students try to get the main idea of it.‎ T: Identify the three robots and number them.‎ Play the tape again and check the answers. ‎ T: Now listen to the tape again and try to complete the chart in activity 3. Pay attention to information about height, appearance, ability and price of each robot. ‎ Play the tape. Stop at the end of each part. Then check the answer. ‎ Step IV Talking TALKING on page 55. ‎ T: Imagine that your family is thinking of buying a robot. You can afford these three robots mentioned in the listening text. Please discuss which one is the best for you. Remember to discuss the advantages and disadvantages of each one. Then make your choice and give reasons. Remember to use the expressions on page 22 in your discussion. You may do it in groups of four.‎ Give students 5 minutes for discussion. Then let some group representatives report their results. e.g. ‎ Our group has chosen the one who can do house work because there are always so much housework do to everyday, and our parents are all busy working and they feel too tired to do house work after work. So if we buy the robot, our families will have more time for fun.‎ The Fifth Period Integrating skills (II)‎ Teaching goals 教学目标 ‎1. Target language 目标语言 liaison and incomplete explosion ‎2.

Let’s listen and check your guess. ‎ Play the tape. Students listen and get the main idea.‎ T: Now listen to the tape again and fill in the chart about Sally and Brenda. Before you listen, read the questions to get the listening points. While listening, make notes. ‎ Play the tape again and let students fill in the form in activity 2. ‎ Check the answers.‎ T: Suppose you have a robot in your home, how would you treat it? Would you treat it like a human or just a machine? What rights should android have? Discuss with your partner and make a list.‎ Sample list:‎ ‎1 They should be able to choose the work they do.‎ ‎2 They should have regular rest time.‎ ‎3 They should be respected like humans.‎ ‎4 They should be repaired immediately after they get broken. ‎ ‎……‎ Step II Reading task T: Have you heard of robots that have been made to play football? We call this kind of robots sporting robot. Today we’ll get to know a sporting robot named Hua Fei. Turn to page 58, read the passage and complete the record card in activity 1. ‎ Students read the passage and complete the chart. ‎ Check the answers.‎ RECORD CARD HUA FEI Ability Jump from spaceship and turn, dive, circle and dance during the falling process Performance in 78th Olympics flying island above Brussels in the sky Prize won Silver medal Performance in 79th ‎ Olympics Failed to perform well Reason for failure A programmer failure Treatment ‎2 new legs and a bigger head to be built Then focus on liaison and incomplete explosion in paragraph 2. First let students find ‎ out the liaison and incomplete explosions by themselves. ‎ Then play the tape and check one by one. ‎ Play the tape again and let students read after it.‎ ‎＊General information on liaison and incomplete explosion: (This material can be ‎ distributed to students as handouts.)‎ 连读 什么是连读: 　在连贯地说话或朗读时,在同一个意群(即短语或从句)中,如果相邻的两个词 前者以辅音音素结尾,后者以元音音素开头,就要自然地将辅音和元音相拼,构成 一个音节,这就是连读。连读时的音节一般不重读,只需顺其自然地一带而过,不可 以加音,也不可以读得太重。如: not at all这个短语。连读时听起来就像是一个单 词。注意:连读只发生在句子中的同一个意群中。在两个意群之间即使有两个相 邻的辅音和元音出现,也不可连读。如: Please take a look at it.这个句子中take a ‎ look at it是同一个意群,那么take与a可连读,look与at可连读,at与it可连读。在There ‎ is a book in it.一句中book与in往往不连读,因为book与in分别在两个不同的意群 中。‎ 连读的详细情况:‎ ‎1.在同一个意群中,相邻的两个词,前者以辅音音素结尾,后者以元音音素开头,往往要拼在一起连读。如: 　　He is a student. (is与a要连读) 　　That is a right answer. (That与is, is和a, right和answer都可以连读) 　　I'll be back in half an hour. (back和in, half和an, an与hour都可以连读)。‎ ‎2.在同一个意群中的两个单词,如果前面的单词以r或re结尾,后面的单词以元音音素开头,则r或re要发/r/音,并与其后的元音音素相拼。如: here and there, a pair ‎ 不完全爆破 什么是不完全爆破:‎ ‎　爆破音是指发音器官在口腔中形成阻碍,然后气流冲破阻碍而发出的音。这 些音有6个,即/p/, /b/, /t/, /d/, /k/和/g/。但在某些情况下,发爆破音时,气流不必冲破阻碍,而只是发音器官在口腔中形成阻碍,并稍做停顿,(也就是说,做好要发出这个爆破音的准备,但不要发出音来),这样的发音过程叫作"不完全爆破"。‎ 不完全爆破的详细情况: 1. /p/, /b/, /t/, /d/, /k/, /g/这6个爆破音中的任何两个音素相邻时,前者发不完全爆破音,后者则要完全地。彻底地进行爆破。如: 　　1) He has a ba(d) col(d) today. 　　2) You shoul(d) ta(k)e care of the children. Gla(d) to meet you. 2.爆破音/p/, /b/, /t/, /d/, /k/, /g/在/tF/, /dV/, /W/, /T/的前面时不完全爆破。如: 　　1) Have you rea(d) the book abou(t) tha(t) child。 　　2) The thir(d) chair is broken. 3.爆破音/p/, /b/, /t/, /d/, /k/, /g/在/m/, /n/, /l/, /s/的前面时不完全爆破。如: 　　1) Goo(d) morning, sir. 　　2) Goo(d) night. 　　3) They are very frien(d)ly to us. 注意:不完全爆破可以发生在单词。短语或句子中。‎ Step III Speaking task ‎ T: After the 78th and the 79th Olympics, Hua Fei became famous all over the world. And many media try to interview him. Now imagine you have been lucky enough to be allowed to interview Hua Fei in hospital for your school newspaper. Work out ‎ some questions in pairs for your interview. Think about the questions or information usually covered in sports newspapers. ‎ After a while T: Now tell me your questions. ‎ S1: How do you say about what you did in the last competition?‎ S2: How are you now and how long will it be before your recovery?‎ S3: Do you plan something new in the future?‎ T: Then, role-play in pairs. One of you will interview Hua Fei. The other will imagine he/she is Hua Fei. Then change roles. While interviewing, take notes of your partner’s answers to the questions.‎ Sample answers:‎ ‎1 I think I’ve tried my best although I was in bad luck. ‎ ‎2 I’m recovering but it’s hard to say when I’ll get pretty well.‎ ‎3 After recovery, I will practice hard, compete once more and try to win the gold medal in the next Olympics.‎ Step IV Writing task Get students prepared for writing a news article about Hua Fei. First help them ‎ understand the structure of the sample passage.‎ T: In a news article, there is a subtitle besides a title, which illustrates the title by supplying more details. And usually in a news article, we use inverted pyramid format. That is to say, the most important information comes first, and then the less important. Now read the passage and tell me what each paragraph is mainly about. ‎ After reading S1: Paragraph one tells about Hua Fei’s present situation.‎ S2: Paragraph two explains how the accident happened.‎ S3: Paragraph 3 includes some comment on this affair and also Hua Fei’s exact words. ‎ T: Now write your own passage following the structure. Remember to include the information from your questions.‎ Sample article: ‎ Dreams never fall Hua Fei, waiting to fly again after recovery This afternoon I had a face-to-face meeting with Hua Fei, the famous sports robot in hospital, who was seriously injured in the robot competition of 79th Olympics. He had two legs broken and a cut on his head. ‎ However, he looked calm and optimistic. “I have tried my best in the competition. I don’t feel regret”. He said the medical equipment is very advanced there and he is quite confident about his future. “It won’t take long before I completely recover.” Hua Fei told us. ‎ When asked about his future plan, Hua Fei said he would practice harder and compete again after recovery. His would try to win the gold medal of the next Olympic. ‎ Step V Project ‎ If time allows, let students work in groups to discuss how computer chips in many different kinds of machines will change the way we do things. ‎ Sample discussion: ‎ S1: I think there will be a computer chip put into a black-board.‎ S2: What would that do to the blackboard? ‎ S3: It could clean the blackboard if we all have seen the words on the blackboard.‎ S1: Yes, we needn’t clean the blackboard by turns and our classmates don’t have trouble of chalk powder.‎ S2: Yes, perhaps when we want to see the words again after lass, it can let us see freely.‎ S3: Or it can make the blackboard record the words of our teacher. I think it’s useful for us to review our English lessons.‎
