Reading Listening Grammar Extensive Reading Speaking Writing
Teaching methods 教学方法 Fast and careful reading; asking and answering activity; individual, pair or group work. Teaching aids 教具准备 A computer and a projector. Teaching procedures ＆ ways 教学过程与方式 Step I Warming Up Show some pictures of life in the past, at present and in the future to the Ss, period by period. First show the pictures of life in China in AD 1005. T: Do these pictures describe our daily life? Ss: No, perhaps they describe life of many many years ago. T: Good. Then can you tell me what life was like one thousand years ago? For example, life in AD 3008. S: Let me try. People living at that time didn’t have cars or planes. They rode horses or took carriages. S: They didn’t have electricity. S: They didn’t live in tall buildings. ... Show the pictures of life at present. T: Good! What about our life at present? What is it like? S: Our life at present is convenient. We live in various kinds of buildings, and we have lots of entertainments. We travel by many modern transportations, such as cars, buses, planes and etc. Show the pictures of life in the future. T: Every day we can come across passages about life in the future in magazines, newspapers and so on. Please look at these pictures and try your best to describe what life in the future will be like. S: Let me have a try. I think in the future we can travel the whole space in a spaceship freely. And perhaps we can communicate with aliens. S: At that time, I think the earth will have been polluted so heavily that no one can
live on it. We perhaps will have to move to other planets to live. ... Then set a scene for the Ss — A special tour guide. T: Now imagine you are working in a tour company which has just promoted a new kind of travel — time travel. Your company can transport people in AD 2008 to the past, also it can transport people in the past to your cities. You are chosen to be a guide for 5 people who want to go back to the China in AD 1005, and also 4 people in that year want to visit the China in AD 2008. How will you organize your trip? What kind of things will you introduce to those people? Give the Ss 2 minutes to discuss. T: OK. Time’s up. Volunteer? S: If I am the tour guide who will take people back to the past, I will introduce them the houses, the way people lived and their clothing. Because these are quite different from ours today, I think people will be very interested in them. S: If the company gives me the chance to take people living in the past to our city at present, I will try my best to provide them an impressive trip. I will introduce something which is different from things in the past to them. For example, transportation, TV, computer and business. Because these have changed greatly as time goes by. T: OK. You have done a good job. Now open your books and turn to page 17. Please work in pairs to discuss the items in the chart. When you finished, complete the chart. Give the Ss ten minutes, and after that, check the answers. Step Ⅱ Pre-reading Get the Ss to discuss the problems that human beings are facing today (such as pollution, all kinds of shortages). Make a prediction about the future: which problems may be solved, and which will still be there. This part will prepare the Ss for the text. T: We all know that as our society develops, we have got much benefit. But at the same time, we have to face lots of problems. Can you find out what kind of problems human beings are facing? S: Pollution. S: Population is becoming larger and larger.
S: The shortage of resources. T: Yes! Then can you predict which problems can be solved in the future? And which ones will still be there? S: I think the problem of population will be solved in the future, because now more and more countries have begun to control the birth rate. S: I think the problems of pollution and shortage of resources will still be there, and will even get worse. S: I don’t think so. Now scientists all over the world are trying their best to develop new resources that human beings can make use of, such as solar energy. In my opinion, the problems can be solved one by one. Step Ⅲ Reading T: Now please open your books and turn to page 17. Let’s read the passage First Impressions. Read it quickly and then tell me what it is about. Several minutes later. T: Well, have you finished reading the passage? Ss: Yes. T: OK. Who would like to tell me what the text is about? S: It’s an e-mail written by a man who has taken up a trip to the future. T: Good. Then look at the following sentences. They are in wrong order. Anyone can tell me the correct order of these sentences? A. We were transported into the future by a comfortable time capsule. B. I arrived at Wang Ping’s home and everything in his house made me surprised. C. I won a travel to the year AD 3008. D. I have my first try to master a hovering carriage. S: C-A-D-B. T: Very good! Let’s go through the first two paragraphs together and get the general idea of Li Qiang’s trip to the future. Then answer the questions on the screen. Show these checking questions on the screen. 1. Why did I have the chance to travel to the year AD 3008? 2. What is a “time lag”?
3. How did I feel when I was in the capsule? 4. Who guides my trip? 5. Why did my guide give me some tablets? 6. Who transported us to the future? A few minutes later, check the answers. Sample answers: 1. He took up the prize he won the year before. 2. “Time lag” means a person gets flashbacks from his previous time period. 3. The seats in the capsule are very comfortable. 4. My friend Wang Ping is my guide to the future. 5. The tablets could help me feel less nervous and uncertain. 6. Wang Ping’s parents’ company transported us to the future. T: Wonderful. Do you want to know more about his trip? Now please go through the third paragraph to get some details on the environment in the future. When you finish, please answer the following questions. Show these three questions on the screen. 1. How did I feel as soon as I was transported to the future? 2. How did Wang Ping solve this problem? 3. What do you think has caused this kind of problem? Give the Ss 1 or 2 minutes to think and they can discuss with their partners. Then check the answers. Sample answers: 1. After the writer was transported to the future, he was hit by the lack of fresh air. 2. Wang Ping gave a mask to the writer and hurried him through to a small room nearby to have a rest. 3. Now we are causing more and more pollution to the nature, this will cause serious problems to life in the future. This may be the cause of the lack of fresh air in the future. T: What will transportation in the future be like? Are there any differences between transportation in the future and that at present? Now please read the fourth and fifth
paragraphs and find out something about both transportation and daily life in the future. After the Ss read the paragraphs, ask them the following questions. 1. What did Wang Ping’s house look like? 2. What was the green wall made of? What’s the purpose of building this kind of green wall? 3. How can you produce a TV set in Wang Ping’s house? Sample answers: 1. His house is a large bright, clean room. It had a green wall, a brown floor and soft lighting. 2. The green wall was made of trees. The leaves of the trees will provide much-needed oxygen to the house. 3. You can just flash a switch on the computer screen and a TV set will rise from the floor. T: So we can see life in the future is much more convenient and much easier than our present life. Step Ⅳ Follow-up Activity Get the Ss to compare life at present and in the future. Find out the changes on several items. Try to distinguish which changes are good and which are not good and give reasons. T: Now let’s make a prediction about future and see what will be changed in the future. I will give you 3 minutes to discuss in pairs, and after your discussion please finish the following chart. Sample answers: Items Life at present Life in the future (Changes) good or bad? Reasons? Environment The development

Sample answer to Ex. 3: I think the writer has an optimistic view of the future. He was very excited when he traveled to the year AD 3008 and couldn’t believe it was true. From this, we can see he is eager to go to the future. Though he was hit by the lack of fresh air, the problem was immediately solved by putting on a mask. And he tells us the transport in the future is convenient. When he arrived Wang Ping’s home, he found there were many trees after the wall moved, and these trees provided the house with much-needed oxygen. Finally he described the automatic equipment in Wang Ping’s with furniture in walls and and floor
house. All the above has shown his view of the future. Step Ⅴ Homework Review the key sentences in the text. The Second Period Listening Teaching goals 教学目标 1.

Teaching aids 教具准备 A computer, a projector and a recorder. Teaching procedures ＆ ways Step Ⅰ Lead-in Let the Ss discuss the following two questions: 1. Do you think time travel is possible? 2. If you have the chance to have a time travel, which places would you like to visit? And why? T: Glad to see you, everyone. Last time we learnt something about Li Qiang’s travel to the future. It’s fantastic, right? In our daily life, we also read lots of novels and watch many films about time travel. Can you name some great movies about time travel? S: Matrix! 教学过程与方式
T: Yes. Good. Do you think time travel is possible? S: I think it is possible. In the past, people cannot travel to the moon, but now they can. So with the development of science, maybe one day, we can travel to the past or to the future. This is quite possible! T: If you have the chance to have a time travel, where would you like to visit? Why? S: I want to visit the space station. In the future, maybe we will find out some other creatures living in other planets. I would like to communicate with them and know something about them. Step Ⅱ Listening Task 1 Let the Ss listen to the material on page 23 twice. After listening for the first time, let them answer some simple questions to check their general understanding. T: OK. We know that Li Qiang had a chance to travel to the future, today we are going to learn where he would visit. Don’t open your textbooks. Just listen. I will play the recording for you twice. For the first time, listen to the general idea Listen again and check the answers. 1. How can “Wonderworld” make sure there is enough oxygen? 2. How can “Wonderworld” make sure there is enough water? 3. What is the advantage of living in “Wonderworld”? 4. Do you think people will be healthy living in “Wonderworld”? Why? Task 3 Deal with the LISTENING on page 55. T: There will be lots of new inventions in the future. Here we’ve got a new kind of quilt. Why is it special? Let’s listen to the tape and try to find it out. Meanwhile we should find out where these quilts are suitable to promote. Play the tape for the Ss twice. Let them do Exx. 1－3 on page 55 and then check the answers. Step Ⅲ Homework After class, let the Ss listen to the three materials repeatedly. The Third Period Grammar Teaching goals 教学目标

Learning ability goals 学能目标 Help the Ss learn how to use the past participle as the adverbial and the past participles the attribute. Teaching important ＆ difficult points 教学重难点 Distinguish the usage of the past participle as the adverbial and the past participle as the attribute. Teaching methods 教学方法 Practice. Teaching aids 教具准备 A computer, a projector and a blackboard. Teaching procedures ＆ ways 教学过程与方式 Step I Word Study This part is a consolidation of the words learnt in this unit. Ask the Ss to do the Exx. 1 ＆ 2 on pages 20 ＆ 21 and exercises in USING WORDS AND EXPRESSIONS in Workbook independently. Then check the answers. Step II Grammar The Ss will learn the usage of the past participle in different situations. Task 1 Make clear to the Ss the usage of the past participle as the adverbial. T: Now please look at the sentence: Worried about the journey, I was unsettled for the first few days. = As I was worried about the journey, I was unsettled for the first few days. 过去分词作状语： 用作状语的过去分词通常来自及物动词。过去分词用作状语时，修饰主句的谓语
动词，意义上相当于状语从句，表示时间、条件、原因、伴随状况等。过去分词 作状语，前边往往可以加 when, while, as if, as though。一般说来，这种结构的逻 辑主语必须与主句的主语一致。例如： Whenever praised, she blushes.（作时间状语） = Whenever she is praised, she blushes. United, we stand; divided, we fall.（作条件状语） = If we are united, we stand; if we are divided, we fall. Written in great haste, this book is full of errors.（作原因状语） = Because this book is written in great haste, it is full of errors.

Although born in Germany, John lives and works in U.S.A.（作让步状语） = Although John was born in Germany, he lives and works in U.S.A. Task 2 Make clear to the Ss the usage of the past participle as the attribute. T: Now please look at these two sentences: 1. I followed him to collect a hovering carriage driven by computer. = I followed him to collect a hovering carriage that / which was driven by computer. 2. Tomorrow you will be ready for some visits organized by the company. = Tomorrow you will be ready for some visits that / which was organized by the company. 过去分词作定语： a. 用作前置定语的过去分词通常来自及物动词，带有被动意义和完成意义。例 如： We like skating in the frozen lake in the winter. = We like skating in the lake which has been frozen in the winter. How many finished products have you got up to now? = How many products that have been finished have you got up to now? 来自不及物动词的过去分词很少能单独用作前置定语， 能作这样用的仅限以下几 个词，这时仅表示完成意义，不表示被动意义： a retired worker = a worker who has retired
an escaped prisoner = a prisoner who has escaped a faded / withered flower = a flower that has faded / withered fallen leaves = leaves that have fallen the risen sun = the sun that has just risen a returned student = a student who has returned vanished treasure = treasure that has vanished b. 用作后置定语的过去分词通常也来自及物动词，表示被动意义和完成意义。 这明相当于一个定语从句。例如： Things seen are better than things heard. = Things that / which are seen are better than things that / which are heard. The lobster broiled over charcoal was delicious. = The lobster that / which was broiled over charcoal was delicious. Then let the Ss do Exx. 1 － 4 on pages 20 ＆ 21 and exercises in USING STRUCTURES in Workbook to consolidate what they have learnt. And check the answers. If time permits, let the Ss learn the following usage of the past participle in the class. 过去分词作表语： 过去分词作表语表示主语所处的状态。用作表语的过去分词大多来自及物动词； 不及物动词的过去分词能作表语的只限于少数表示位置转移的动词， go, come, 如 assemble 等，它们用在联系动词之后，表示完成意义，无被动意义。例如： The man looked quite disappointed. He is greatly discouraged by her refusal. His hair is nearly all gone. 已经形容化了的过去分词大多可作表语，常见的有: accomplished, amazed, amused, astonished, broken, closed, completed, complicated, confused, crowded, devoted, disappointed, discouraged, drunk, excited, frightened, hurt, interested, lost, satisfied, surprised, worried 等。 过去分词作宾语补足语： a. see, hear, feel, find, think 等表示感觉和心理状态的动词可以带过去分词作宾语
补足语。例如： Tom found himself involved in an awkward situation. I saw Tom dressed like a beggar in the street. Everybody thought the match lost until the last minute. b. make, get, have, keep 等表示“致使”意义的动词可以带过去分词作宾语补足语。 例如： I have my clothes washed everyday. Don’t get your schedule changed; stay with us in the class. He’s trying to make himself understood.

Teaching important ＆ difficult points 教学重难点 Talk about the possibilities of living under the sea. Teaching methods 教学方法 Fast and careful reading; asking and answering activity; discussion. Teaching aids 教具准备 A computer and a projector. Teaching procedures ＆ ways 教学过程与方式 Step I Warming up Lead in the topic by discussing the possibilities of living under the sea. Encourage the Ss to use their imaginations. T: Have you ever watched the movie “The Little Mermaid”? Do you like the sea? I myself like the sea very much. I always think that how great it will be if I have the chance to live under the sea! Do you think living under the sea is possible? Why? Now please work in pairs to discuss the three questions on the screen. Show the following questions on the screen and hold a discussion. 1. Do you think living under the sea is possible? 2. Where are you going to live under the sea? 3. In the undersea cities, what equipments do you think are necessary? Ten minutes later, ask some Ss to answer the questions. T: Have you finished? Who would like to tell us your opinion? Volunteer? S: I think it’s possible. Maybe in the future scientists will invent some kind of equipment that makes it possible for human being to live under the sea. T: If it is possible, where are you going to live under the sea? There is all water and fishes around you. S: Maybe in a special equipment which will provide us much-needed oxygen and can float in the water. In that case we can travel in the sea to enjoy the wonderful view of the sea. T: Good. If you are going to live under the sea, what kind of equipment do you think is necessary for your living? S: Oxygen provision and cleaning machine may be necessary.
Step Ⅱ Reading Deal with the passage on page 58. T: OK. From what you said, I know all of you are looking forward to living under the sea. Now a company just provides the very service! Please turn to page 58 and read the passage RISING TO A CHALLENGE. Let’s see what the life will be like in this undersea city. When you finish reading, complete the sentences on the screen. Give the Ss 3 minutes to go through the whole passage. 1. The undersea city is so comfortable that it is described as ___________ . 2. The undersea city has the following advantages: a. _____________ b. _____________ c. _____________ d. _____________ T: Can you find out some suitable sentences or words to fill in the blanks? What’re the advantages of living under the sea? S: The undersea city is so comfortable that it is described as “a silk adventure”. S: The undersea city has the following advantages: a. easy contact with the land surface; b. more personal space; c. complete personal security; d. no housework worries. T: That’s great. You all have got the general idea of the passage. Now let’s look into some detailed aspects of the undersea city. First let’s look at its contact with the land surface. Who would like to tell me at the very beginning, what kind of problem were they facing? And how was the problem solved? S: The sea bottom is so deep that it’s hard to contact with the land surface. But later they invented the one-person or family shuttle-submarines which will always be ready to take people to the surface. T: So in that case people who live under the sea can easily contact with the land surface. Then com-paring with living on land, what advantage do you think can attract people to live under the sea? S: We can get twice as much personal space as in flats on land.
T: Good! Then what kind of special equipment will be provided so as to realize all the advantages? Please read the text again and finish the following chart. You can work with your partners. Show the chart on the screen and give the Ss 3 minutes to go through the whole text again to scan for the answer. A few minutes later, check the answers. Advantages Special equipments How does it become
realized? Easy contact with land One person or family Always ready to take
people to the surface, a special small,
computerized machine to monitor each person
during the trip. More personal space Get twice as much
personal space as in flats on land, your house can float in the water. Complete security personal Computer sensor Can feel the space left; only when the robot
cleaner touches objects can they be moved. No house- work worries Family used robots Feed your details into the computer hard-drive;
answer your commands. T: This undersea city is amazing. But I think designing such kind of undersea city is quite difficult! Do you want to meet its designer? Now the designer of the city
William Lee is being interview. Let’s listen to his interview and find out which two problems he came across and how he solved them. Then please finish the exercises on page 59.
... Step Ⅲ Follow-up Activity Set a scene for the Ss: The company is going to held a press conference and exhibition. Encourage the Ss to design a poster which will draw visitors’ attention and provide some useful information. T: We know that all new products have to be promoted so that it can be well-known among people. Now a press conference and exhibition is going to be held to make the undersea city known to people. If you work in the company, can you design a special poster to draw visitors’ attention so that they will come to the press conference? Use your imagination and you can discuss with your group members. A Sample poster:
Come to this meeting See the value of OUR undersea houses. Saturation City has: ● easy contact with the land surface ● more personal space ● complete personal security ● no housework worries Cost: 20 dollars Date: May 18th Time: 8:00 am Place: The Science Exhibition Building Step Ⅳ Homework T: After class, please listen to the tape repeatedly until you can retell it yourselves and
pay attention to pronunciation. The Fifth Period Speaking Teaching goals 教学目标 1. Target language 目标语言 Make predictions: Suppose that... I wonder if... Is it likely / unlikely that...?

Teaching procedures ＆ ways 教学过程与方式 Step I Talking Set a scene for the Ss: A man who is living in AD 2046 comes to visit your city and wants to know something about jobs in your city. Ask the Ss to work in pairs to make out an introduction plan. Make a comparison between jobs at present and jobs in the future, and find out the changes and why these changes take place.
T: In the first period of our unit, we discussed the changes between life in the past and life at present, also we make a prediction about our future, right? Today let’s still talk about the future. Suppose a man of AD 2046 comes to our city, he wants to know something about jobs in our city. How will you introduce the following two kinds of jobs to him? Teachers and farmers. Give the Ss 1-2 minutes to discuss and then ask some of them to represent their opinions. T: OK. Who would like to talk about the job as a farmer? S: Nowadays farmers are still working very hard. Few of them use hi-tech machines, especially in developing countries. They have to work most by hand everyday. Sometimes they will use some machines such as trucks, seeding-machines, etc. In developed countries, agriculture has been computerized. Farmers in those countries are much easier. T: Good. What about teachers? S: Nowadays lots of students stay in the classrooms to listen to their teachers. And the teachers have to use chalk, and sometimes they use computers. Set another scene. T: So it seems that both these two kinds of jobs are very challenging. Will they change in the future? Now the man invites you to his city in the year 2046, what changes will you expect to find on these two jobs? S: I think 40 years later, working as a farmer will be much easier than now. Farmers won’t have to work by hand, they can set a program in the computer and then the computer will finish all the tasks. It’s fantastic! And the harvest will be much better because of the science. S: I think in the future we don’t have to come to school to study. Teachers will work on the Internet. We will have classes through the Internet. And unlike today’s teacher, in the future, a teacher can teach many subjects. And we will have robots do teaching jobs. T: So maybe I should be born 40 years later, in that case, the job for me will be much interesting.
Step II Follow-up Activity Encourage the Ss to predict their future life and make a short-term plan. Let them talk about their dreams and then write passages introducing these dreams. T: Everyone, have you ever dreamt of your own future? Have you asked yourself what you will be? Now let’s make a prediction, or we can say, let’s make a plan for ourselves: What will I be in the future? You can discuss with your partners to fill in the following chart and then write a passage introducing your dreams. Show the Ss the chart on the screen. Time What will you do? Where will you be? How will you prepare for it? 1 year later 5 years from now 10 years from now Give the Ss enough time to discuss. This will help them make clear of their own future. And then select some Ss to give a report to the whole class. Step Ⅳ Homework T: Imagine you are at your age of 30. Write a passage to describe your daily life or your experience. A sample version: It is the year 2020 and I have just turned 30 years old. More than 10 years ago, I left high school and went to study at a good university. I was a history major and I also studied two foreign languages. After graduation, I was offered a job teaching history in a middle school. At first, I didn’t think I’d like to teach history. I thought the students would think history was too boring. My first year was very difficult. I didn’t know much about teaching and the students did not like my lessons. But I was lucky. One of the older teachers became my friend and taught me a lot. The Sixth Period Writing Teaching goals 教学目标 1. Target language 目标语言

文化背景知识 TIME TRAVEL Shaping the future The idea of traveling forward into the future or back into the past has always fascinated science fiction writers. The “grandfather paradox” is the argument that many people use to suggest that time travel is impossible. What if you went back in time and prevented your grandfather from meeting your grandmother so that your mother was never born? Then you would never have been born ... and so on. Until very recently such arguments led most scientists to believe that time travel could never exist outside science fiction. But amazingly, some interpretations of the weirdness of the quantum world now suggest that time travel is possible — at least in theory. Gravity and black holes Einstein’s theory of relativity brought space and time together in a single, four-dimensional arrange-ment that he called space-time. We know that we can travel forwards, backwards and sideways in space, so why not forwards and backwards in time? Four dimensions are difficult to imagine, so physicists usually suggest you think of space-time as a rubber sheet stretched out flat. If there are no large masses around,
the sheet stays flat, and so any object placed on it will move around in straight lines. But a large mass, such as the sun, makes a dip in the sheet because it actually warps space-time. Now any other object with smaller mass, like our earth, moving about in space-time rolls into the dip as it comes past the sun. It appears “attracted” to the large mass. This effect of warping space-time is what gives rise to gravity. The Universe is full of heavy objects exerting gravitational effects and the net result is that space-time is not flat at all but curved. Everything, including light, has to follow curved paths in space-time. We know Einstein was right about this because astronomers can sometimes see distant stars that ought to be masked by nearer objects such as the sun. Instead of traveling in straight lines and hence being blocked, the light from the stars bends round the obstruction. When a star reaches the end of its life it mat collapse inwards under the influence of its own gravity to such an extent that all its matter becomes concentrated into an extremely dense object, a fraction of its original size. This is a black hole. Black holes have such a huge gravitational pull that nothing can escape from them, not even light. We cannot see them but we have good evidence that they are being pulled about by a nearby invisible object with enormous mass. What does a black hole do to space-time? Relativity predicts that at the center of a black hole is an infinitely dense point, called a singularity, within which all the normal laws of physics no longer apply. Time, space, matter and energy no longer have any well-defined meaning. Einstein’s equations show that such a singularity doesn’t just make a dip in the imaginary rubber sheet of space- time, it makes a tunnel that goes right through and momentarily opens out on the other side. Where is “the other side”? It could be somewhere else in space-time, either in the future or in the past, or it could even be in another Universe! Supposedly it was Derwood’s Time lords who first harnessed the power of a black hole to begin their experiments in time travel. If you could take a space trip through such a tunnel, or wormhole, you would have discovered the secret of time travel. This is of course impossible with today’s technology. But in the future, who knows? Many worlds, many futures?
To return to the question that has puzzled thinkers since Newton’s day, is the future preordained? Or are there a quantum world suggests that not only are there an infinite number of futures? One way of looking at the quantum world suggests that not only are realized in an infinite number of universes. Photons and electrons sometimes behave as waves and sometimes as particles, but never both at the same time. So far, the argument for interference between one universe and another applies only to events occurring at the quantum level. But the idea of parallel universes provides a possible resolution to the “grandfather paradox” that might otherwise cause problems for time travelers. If we travel back in time and change history, we launch ourselves into a new future in a parallel universe — but we have no effect on the present one from which we started out. Scientists of the future may well pursue a new form of futuristic technology based on quantum effects. Such applications could include quantum teleportation, by which a quantum particle can be teleported from one point in space to another; and quantum computation, where calculations can be carried out which would take many years on a conventional computer. Although we now know how to measure time very accurately, have we come any nearer to answering the basic question “What is time?”. Pleiades The Pleiades is known as the Seven Sisters and Messier 45. It is roughly 500 light years from Earth. There are actually about two hundred and fifty to five hundred thousand stars with this cluster that have been counted including the 7 major ones that have been known throughout antiquity. The cluster contains thousands of stars, of which only a handful can be seen by naked eyes. The stars in the Pleiades are thought to have formed together around 100 million years ago, making them 1/50th the age of our sun, and they lie some 130 parsecs (425 light years) away.
