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 shuttle-submarines

 

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 personal security

 

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 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

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.

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.
