Learning ability goals 学能目标 Help the Ss learn how to describe the life in the past, at present and in the future.‎ Teaching important & difficult points 教学重难点 Compare life in the past, at present and in the future.‎ What is life in the future like? What changes will take place?‎ 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 Air pollution and water pollution; resource shortage The situation will get worse and worse The development of our society will cause human being to develop more and more resources; and the development of industry will cause worse pollution to our environment Transport Airplane, car, train, boat and helicopter Spacecraft, time travel, personal flying car or bike More convenient Education People receive education in school People receive education on the Internet; can choose the subjects and the teachers they like Have more chances to receive different knowledge Houses Flats in high rise buildings; with kitchens and bathrooms Cozy, modern flats, furniture in walls and floor Then let the Ss do Exx. 2 & 3 on page 19. A few minutes later, check the answers.‎ 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 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.

Can you name some great movies about time travel? ‎ S: Matrix! ‎ T: Yes. Good. Do you think time travel is possible? ‎ S: I think it is possible.

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.

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.

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!

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.

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.

There are all kinds of entertainments of all aspects so that everyone will be able to fully enjoy themselves.‎ ‎ All entertainments are offered. If you go to the entertainment center, you can have the chance to practise dancing, singing, and playing musical instruments. Of course, you have the chance to enjoy wonderful concerts by different singers, such as pop concerts, classical concerts and operas. And also you can enjoy the latest films and TV operas. ‎ ‎ The company will organize some perfect performances. We will offer permanent band to play for dancing every night. Also we will invite different stage companies to come to our entertainment center to give wonderful plays. ‎ ‎ We hope that these programmes and facilities will help you relax yourselves. We hope that you will come and try our entertainment center for yourselves.‎ 附 件 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.‎
