    Tom and Fred were talking about the year 2050. "What will the world be like in the year 2050?"asked Tom. "I don't know, "said Fred. "What do you think?" "Well, no one knows. But it is 1 to guess, "said Tom. "In the year 2050 everybody will   2a pocket computer. The computer will give people the answers to all their problems. We shall all have telephones in our pockets, 3 . And we'll be able to talk to our friends all over the world. Perhaps we'll be able to see them4 the same time. Machines will do 5 of the work, and people will have more holidays. Perhaps they will work only two or three days a week. They will be able to fly to the moon by spaceship and spend their holidays there. ""I'm very glad to hear that. I hope to fly to the moon. And I hope I'll be able to live 6 ,"said Fred. "Won't that be interesting? Just like a fish. "

    Would you like to live in a city where buildings turn the lights off for you, and self-driving cars will find the nearest parking space themselves? Although it might sound a little far from you, living in a "smart" city like this could happen sooner than you think.

    Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a "telepresence" system (远程监控系统)—allowing users to control the heating and locks, take part in video meetings, and receive education, health care and government services. Around the city, escalators (自动扶梯) will only move when someone is on them, and offices and schools will all be connected to the system.

    The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business.

    About 75% of the world's population will live in cities by 2050, so cities will need to be more modern to deal with the coming problems. "Making cities smarter is one way out, and I think this will in turn make cities greener," said Dan Hill, head of a research company.

    What differences will there be in the year 2100? No one knows. But it is fun to have a guess at it.

    Let's make this story about you in the year 2100. Our story will be about one day only.

    You wake up at seven in the morning. You get dressed. Guess what the clothes are made of. Paper? Glass? Or something we don't even know about today?

    You will spend no time cooking breakfast. Why? The food may be ready for eating. Now you start for work. But you don't go by car. You step on to a moving sidewalk. It moves you along to a train station. There you take a train. How will it run? On one rail high over the street? Or will it ride in air? Three o'clock comes. Your work is over for the day." I'll call Tony, a friend of mine," you say.

    Tony answers the videophone(视频电话).You and he can hear and see each other.

    "What shall we do this Saturday?" you ask." Shall we put on your rocket belts (带子)and take a short trip? Or shall we go for a ride in a flying boat?"

    Tony may say," I want to ride in a rocket ship! Let's fly to the Moon!"

Would you like to travel space？

    It is 2050. Space tourism has become a reality. So would you want to be a space tourist？ Here, some middle school students share their opinions.

    Jeea, U.K.

    I love space very much and would like to be the first teenager to da new planet. Then perhaps it would be named after me. I would become famous around the world!

    Emily, U.S.

    Space exploration can be dangerous. What should I do if I get l？I can't come back to the earth. I am also afraid of heights. It would be very frightening when you look down from a spaceship!

    Klaudia, Spain

    I would love to go to space because from there I could enjoy a nice v of the Earth. The blue oceans and green forests on the Earth must be magnificent. What's more,I am curious about what life is like without gravity (重力). Perhaps it would be fun to play golf in space!

    Edward, U.K.

    It would be cool. But how lonely and depressed I would be without aaround me! I would miss my family. It also requires a large amount of training to become a space tourist, and I don't think I have time for that. Moreover, I don't think I can aa trip to space. That would definitely cost a lot!

    Zainab, South Africa

    I'd love to. We studied the solar system in Science classes this semester. I think space is amazing and I desire to know more about it. Unluckily, I have no other way but to search for information about it o. If I can have the chance to travel to space, I would directly see the things I never see on the Earth.

    Ana, U.S.

    I would not like to be a space tourist. I respect those who love space tourism. For me, I only want to f on what I have on this planet - my family, my school and my pets. I would like to work hard to make progress in what I am doing.

    Now cities are full of cars. Some families even have two or more cars Parking (停车) is serious problem, and so is the traffic around the cities. Something will have to be done to change them. What will the cars of tomorrow be like?

    Little cars may some day take the place of today's big cars. If everyone drives little cars in the future, there will be less air pollution. There will be more space for parking cars in cities, and the streets will be less crowded. Three little cars can fit in the space now needed for a car of the usual size. The little cars will cost less to own and to drive. Driving will be safer, too. What's more, these little cars can go about 65 kilometers an hour.

    Little cars in the future will be fine for getting around a city, but they will not be suitable for long trips. If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some roads will be used for the big and fast cars, and other roads will be needed for the small ones.

    It's hard to turn down a tasty banana. They taste good and you don't have to wash them before eating them. However British scientists say that the fruit may disappear by 2050.

    One reason for this is climate change. Scientists at the University of Exeter collected data from 27 countries and regions that produce 86 percent of the worlds bananas. They found that climate change has improved growing conditions in 21 of these countries. In the past 60 years, the average yield has reached 1.37 tons of bananas per hectare.

    However, if temperatures keep rising, this advantage will disappear. Ten of the countries, including India, the world's biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out.

    Shouldn't bananas grow more easily if it's hotter outside? In fact, the perfect temperature for growing bananas is between 24℃ and 32℃. If temperatures get too high, they will stop growing.

    Diseases are another danger to bananas. Unlike other crops, the bananas we grow come from shoot cuttings rather than seeds. This means that all banana plants have the same genotype. In other words, if a disease is able to kill one plant, it could kill them all.

    One serious disease is called Panama. It spreads easily. It has spread across South Asia, Africa, the middle east, and australia. If one banana plantation suffers from the disease, it will take 30 years until it is able to grow bananas again. Scientists have yet to find a cure for this disease.

Mars is an empty planet, but that could change. Someday, it might have farms where fruit and vegetables could grow.

Growing food on Mars has always seemed hard. But scientists think they have found a way to do it. They put sheets(薄膜) of material on the ground. The sheets could change the cold, dry planet into land for farming.

Robin Wordsworth worked on the sheets at Harvard University in Massachusetts. He said the sheets could let people live on another planet. On Mars, the conditions are not good, though. Most importantly, the planet is cold and dry. The soil might have polluted parts, and the air does not have much nitrogen(氮气) that plants need to grow.

The sheets do not solve all the problems. Still, they could help to set up a place for plants. The plants would grow only under the sheets. So there is less worry about harming the rest of Mars. The sheets would cover the plants.

The scientists worked with sheets about an inch thick. Those allowed light through for plants. They also warmed the ground and trapped enough heat to melt ice on Mars. Placing the sheets over icy parts of Mars could let plants alive there. Their study was printed in Nature Astronomy. The sheets could be on the ground to grow water plants and they also could be hung. That would give room to plants to grow on land below them.

Wordsworth said, "You can imagine this being used in a number of ways. It could be used for visitors to Mars. Later it could be for people who live there. However, it's a pity that the sheets are being studied in the lab."

It's March, 2050.

Frank and Mary Smith wake up in their comfortable house in the morning and turn on the bedroom computer to get the news. They used to read the Times, but changed to electronic newspapers many years ago.

There is the usual news about space: another space flight has returned from Mars and scientists have discovered a new planet. As they watch the screen, Mary orders(命令) one of the household robots to make coffee for them.

Frank disappears into the study to join a video conference(会议) with his partners around the world. He is a computer engineer and this is his third job: he used to be in marketing and then television.

Mary has a quick look at the shopping programs before picking up the video phone to talk to her assistant(助手). She also has a job and she is doing medical research. Both she and Frank used to have an office desk in London, but in 2014 they decided to move to the seaside and work from home.

Frank and Mary have one daughter, Louise, who also has her own workstation at home. She goes to school only one day a week, mainly to play with other students. Classrooms disappeared in 2030 because there was no longer any need for them: communication systems(系统) have made it much easier to learn at home.

Louise, now thirteen, is studying Chinese at present, which has become a world language as important as English. Louise has many Chinese friends. They communicate on the Internet.

According to the family doctor, Louise will live to be at least 130 years old. Her wish is to work for a few decades (十年) and then spend her time on music and painting.

    Facebook says it is working on technology to allow us to control computers directly with our brains. It is developing "silent speech" software to allow people to type at a rate of 100 words per minute, it says. The project, in its early stages, will require new technology to detect brainwaves without needing invasive operation. "We are not talking about monitoring your random thoughts," assured Facebook's Regina Dugan. "You have many thoughts, and you choose to share some of them. We're talking about monitoring those words. A silent speech interface(界面) — one with all the speed and flexibility(灵活) of voice. "

Ms Dugan is the company's head of Building 8, the firm's hardware research lab. The company said it intends to build both the hardware and software to achieve its goal, and has employed a team of more than 60 scientists and academics to work on the project.

On his Facebook page, Mark Zuckerberg added, "Our brains produce enough data to stream four HD(高清) movies every second. The problem is that the best way we have to get information out into the world-speech can only send about the same amount of data as a 1980s modem. We're working on a system that will let you type straight from your brain about five times faster than you can type on your phone today. Finally, we want to turn it into a wearable technology that can be produced in quantity. "

Technology is going to have to get a lot more advanced before we can share a pure thought or feeling, but this is a first step. Other ideas detailed at the company's developers conference in San Jose included work to allow people to "hear" through skin. The system, comparable to Braille, uses pressure points on the skin to pass information. "One day, not so far away, it may be possible for me to think in Chinese, and you to feel it instantly in Spanish," Ms Dugan said.

What will our homes be like in the future？Here are some predictions：

◆Want to take a shower when you get home？You'll be able to let your smart water heater （热水器） to start heating up when you're on your way home.

◆Did I turn off the oven？Did I close the window？Everyone may have a moment like that. But in the future, your home will check these for you.

◆In your home of the future, all of your devices can work together to make your life more comfortable. When you turn on the lights in the morning, your windows will open at the same time. The lights will slowly turn off by themselves after the sun appears.

◆Your home may have dangers. The hackers （黑客） could open your door and make your room messy through your phone or other devices. Your home will tell you about it but you can't arrive in time. So people will have to be careful of their personal information.

What do you think the future will be like? Here are more answers from some students.

I think that the world will be an easy place to live in. We 1have machines and robots and they will 2us do all the 3 jobs, and we don't have to do things 4washing dishes and 5 the beds, though we won't have any dishes at all. Maybe we will just throw the dishes away after each meal. I 6that doctors will be able to 7 us alive 8 a long time. I hope that when I am 80 years old, there 9 something that will keep me alive for 10 80 years, so I will live to be 160 years old.

Dear Mike,

Can you believe I'm in a school of 2080 now? The school is like a beautiful garden. The wall of our classroom is colourful. Our school life is interesting and wonderful.

In the morning, we have three lessons. We study on the Internet. We use the e-book. The teachers are all robots. They are of different sizes and they can answer any question about any subject. Our robot music teacher plays the violin very well. In the afternoon, we go to Mars to have two classes in a new plane that looks like our plane and spaceship. I can make friends with aliens. They are friendly and know us well. After class, we play football with aliens. Then we go back to the earth. Don't you think the life in this school is very interesting?

Yours,

Mary

    I'm Nick. I like swimming, so my dream house should be by the sea. The house has a lot of windows and I can look out at the sea. There is a big living mom in the house. I can invite all my friends to have a party in it. My bedroom is blue, just like the sea. It is my favorite color. The blue room can make calm (平静的) ，so I can have a good rest at home.

    I'm Sandy. I don't want a big house and my dream house is a tree house. There is a small bed in it. I can lie on it, watching beautiful stars at night. I like reading, so you can find a bookshelf (书架) in my tree house. There are also some boxes full of my toys. But there isn't a computer in the tree house. So I can completely relax (彻底放松) myself in this small world.

    My name is Lisa. My dream house is a castle. It's white with red roofs (屋顶) . There is a garden in front of the castle. The garden is full of trees and flowers. My bedroom in the castle should be very large. Its walls are green, because it is my favorite color. I. like playing computer games, so there is a computer in my bedroom.

"Frank, get up! It is seven o'clock, September 25^th, 2298. Time to get up and go to school," says the clock robot.

Then the kitchen-robot gives him some bread and eggs. Frank doesn't like them, so the kitchen-robot gives him a hamburger. After Frank eats the hamburger, the clothes-robot gives him his clothes and dresses him very fast. Then Frank goes to school.

When Frank goes outside, he sees a car waiting for him. The car says, "Hello, I will drive you to school. Your name is Frank, isn't it?" "Right," Frank answers. "Now would you please show your school ID card?" says the car. Frank shows the car his school ID card. "Get in," says the car. So Frank gets in. when they get to the school, Frank says to the car, "Goodbye, see you later." The car says to Frank, "I will meet you after school. Good luck in your school."

I'm going to the sun on my holiday. I will go there by spaceship.

I will take a big blue spaceship. Then I'll take the spaceship to the sun. The sun is very hot. So I put on the super shirt. In the morning, I will have some sun hamburgers for my breakfast. At eight o'clock, I will play with my friends there. They are a super dog and a super girl. The super dog is white and black. The super girl is very clever. The super girl and the super dog like to play with me.

So I play with them for an hour and a half. Then I will do my homework on a small blue table. After finishing my homework, I will have my lunch. I will eat sun salad. I will have red juice, red fish and red rice. All things are red. Then I need a lot of water because the sun is hot. Then I will walk to the spaceship. After that I will take the spaceship to the earth.

This is a wonderful holiday on the sun.

On Dec. 25, 2021, a new age of space science started when NASA set up the James Webb Space Telescope (望远镜). It will change our understanding of space.

According to NASA, Webb is the world's largest and most powerful telescope. The old Hubble Space Telescope mostly sees what we see- visible light, But Webb sees infrared (红外线的) light, which is invisible to the human eye. It can make new discoveries by examining stars inside those dust clouds. It will be able to "look at" the first light after the Big Bang (宇宙大爆炸) which created our universe, as well as how young stars grow.

Webb "sees" by using mirrors to collect infrared light from the universe. The bigger the mirror is, the more details it can see. The telescope is as tall as a three-story building and as big as a tennis court. It is so big that it has to fold its mirrors to fit inside the rocket. Once in orbit (轨道), they will unfold, creating one large mirror.

The telescope flew 29 days to reach its orbit, which is more than one million kilometers away from the earth. After six months, it sent back its first picture.

The building of the telescope started in 2004. About 40 million hours of work, thousands of scientists from 14 countries, 10 billion dollars and 1 heavy-lift rocket made it all possible.

Now it's ready to help us answer key questions, such as where we came from and whether we're alone in the universe,

Schools keep changing. Every year, new inventions and products appear. Some of them are very helpful for students and teachers. Which of them will schools use? No one is sure, but here are some possible developments. Do you believe they will come true?
