1 . It’s a typical day at school. You’re playing soccer with your friends. One of them kicks you the ball and you run for it. You trip. You fly through the air. You land—hard, right on your face! The next moment, you’re in the nurse’s office. Your bleeding nose is being checked by laser sensors (激光传感器) that coming out of a...robot? Has the nurse’s office been taken over by sci-fi aliens (外星人) from outer space?
No. You’ve just been pushed forward 15 years into the future. And it’s a future that Susan Epstein, a computer science professor who teaches artificial intelligence, is really excited to think about. “I am crazy about this kind of thing! You could go up to the robot, put your nose in, and the machine would decide whether you needed to be treated, and how.”
Aside from being cool, an AI nurse has other advantages. It doesn’t need to take vacations. It doesn’t need to get paid a salary. And it might figure out what’s wrong with your nose faster than a human would. There are all kinds of ways that AI could be used to help make us healthier and researchers are studying how to use AI to diagnose (诊断) lung disease, cancer, and more.
Our robot nurse isn’t meant to completely take the place of humans, though. “It would work with real, live nurses and doctors,” says Epstein, “there are things humans are good at, like building trust among members of our own species or comforting someone who’s hurt or sick. A big part of medicine is the relationship between a doctor and a patient.”
Epstein points out that AI programs will never be perfect—no matter how much we might want them to be. But if AI can diagnose a deadly disease more precisely even 10 percent of the time, think of how many lives it could save. “Besides”, says Epstein, “I think there are probably patients who might prefer to have a machine for a doctor!” Would you?

2 . Here is a page from a magazine called Future. Read the following information about things that may happen in twenty years.
Cars will run on solar power and will be much cleaner and safer. For example, if you are too close to another car or if you are driving dangerously, your car will slow down or stop by itself. It not only prevents the pollution of the environment but also decreases the rate road killers.
New cities will have to be built in the sea. Some cities on water will have two levels (层). People will live on the upper level; the lower level will be used for traffic, shops and factories, which will be a better way of solving the problem of increasing population and cities.
Biotechnology (生物技术) will make everything we eat better and healthier. Plants without insects or illnesses (病虫害) will be developed. The taste of fruit and vegetables will be better and food will be kept longer. At that time, people will have no need to worry about whether their diet is safe or not, because these foods have been tested again and again. They surely are safe.
Ways of curing illness
Many new ways to cure illnesses will be found. People will use products of genetic engineering (基因产品) to cure more illnesses. However, some new illnesses will appear.
A. New energy used on transportation
B. Green food
C. Ways of keeping healthy
D. Future living conditions
3 . Do you want to travel back in time? What about traveling into the future? There’s an easy way to do it.
One way you can make a time travel journey is by writing a letter to your future self to be opened in the future. To your future self, the letter will be a visit to the past. What can be gained by writing a letter to yourself? It depends on how good your letter is. You have the chance to say something to your future self. What would you want to communicate? You’ll be able to talk to yourself 5, 10, 15 years down the road. There may be instructions for your future self, or you may have goals that you will want to check up on.
There are a lot of things you could include in your letter or letters to yourself. The more you include, the better the letter will be to you. Here are some ideas of things to include in your letter:
Your thoughts and feelings about life, religion, politics, society, etc; Your feelings for your family; Your likes and dislikes; Your dreams; The type of person you want yourself to become...
Be creative with what you put in your letter. Include a picture of yourself or family to show the period from which the letter came.
You can store your letter in a number of different ways. You can give your letter to a friend or family member to keep and mail to you. If you can get others to take part, have them write letters to themselves as well and ask someone to be the letter holder until it’s time to send the letters. You can also use a service online to store your letter and e-mail it to you.
Make the most of your letter writing, and you’ll help your future self make the most of the present.

4 . Futurologists are making a lot of predictions about our future life and they are predicting how we will travel, work and live in the next 30 years. By 2048, some futurologists foresee that some talking" buildings will appear in our life.
By the middle of the century, it’s believed that buildings will be able to “talk" to people through various sensors when the heating needs to be turned on. As a result, there will be no switches. Instead, a lot of networks will appear, which can be compared to a human nervous system. In the next 30 years, buildings will be made from concrete plastics and shape-changing materials. All of them can heal themselves at that time. As architects (建筑师)are racing to develop the world's tallest buildings, there will be a need for new kinds of elevators, through which vehicles could even travel into the buildings. German engineers have already started working on such technology called Multi.
By mid-century, scientists believe that buildings will be miles tall. Some of them may be very large and they can function as small cities. By comparison,at present, the world's tallest building, the Burj Khalifa in Dubai, measures 829. 8 metres high. As the future building can rise through the clouds,their windows will be replaced by virtual screens. In this way, people can choose any view as they like.
At height extremes, a London Spaceport is also likely to come into being by 2048 as the space industry develops very quickly. There is a huge cost advantage going to space from as high a base as possible, so a spaceport is very likely to be over 10km and even as much as 30km, using carbon- based materials.

5 . It’s 2035. You have a job, a family and you’re about 40 years old! Welcome to your future life.
Getting ready for work, you pause in front of the mirror.
“Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronics(智能电子元件) are re-arranged in your shirt to change its color. Looking into the mirror, you find it hard to believe you’re 40. You look much younger.
With amazing advances in medicine, people in your generation may live to be 150 years old. You’re not even middle-aged! As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear, “To lose weight, you shouldn’t eat that.” from your shoes. They read the tiny electronic code on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible foods appears on the counter as the kitchen checks its food supplies.
“Ready for your trip to space?” you ask your son and daughter. In 2005 only specially trained astronauts went into space —and very few of them. Today anyone can go to space for day trips or longer vacations. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor said you need these for space travel.” Thanks to medical advances, vaccination shots(防疫针) are a thing of the past. Ordinary foods contain specific vaccines. With the strawberries in their mouths, the kids head for the front door.
It’s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office, Autopilot,” you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video film rather than read it.

6 . Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict.” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes—khaki pants and a sports shirt—to the office. He hardly ever wears a necktie. “I am working harder than ever.” David says, “and I need to feel comfortable.”
More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday (but only on Friday). This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.” said business consultant Maisly Jones.
Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code.” “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative(保守的)dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss and Company, 85 percent of employers said that they believe that casual dress improves employee morale(心境，士气). Only 4 percent of employers said that casual dress has a negative influence on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”
