1 . Space tourism is the term used to describe space travel for recreational or leisure purposes. What was once only a dream, as described in A Space Odyssey by Arthur C. Clarke, is now becoming a reality.

Futurologists attempt to make predictions of what life will be like in the future. After the first man landed on the moon, they thought that hotels would be built on the moon by the year 2000. They also considered the possibility that, in the 21st century, families might go for a holiday on the moon. Neither of these predictions have come true yet-but the rapid development of technology may mean these predictions are possible in the years to come.

Space Adventures is currently the only company to have succeeded in sending paying passengers into space. It worked with the Federal Space Agency of Russia and Rocket and Space Corporation Energia to provide flights for the world’s first private space explorers. Each paid over $20 million for their 10-day trip to the International Space Station.

Following successful explorations into space, other companies are now considering the possibility of enabling tourists to visit space. To make it affordable, suborbital space travel is being considered by some companies, like Virgin Galactic. Passengers would be transported to a height of between 100 and 160 km above earth, experience 3 — 6 minutes of weightlessness and a view of the stars before back to earth. This is expected to cost around $200, 000 per person.

Whilst it could be an enriching experience, there are some disadvantages. Many critics say that a huge growth in the spaceflight industry could drastically speed up the process of global warming. The ozone layer would be damaged further and the polar regions would suffer. In addition, space travel is only really affordable for the super-rich, though Virgin Galactic claims to be ‘opening space to the rest of us’.

2 . What the future school will look like is difficult to make clear, but most experts agree that the school will be electronic in the future.

“Present-day schools will no longer exist in the next century,” says a report in The Age. “At that time, schools will become community-style centers, which run seven days a week, and 24 hours a day.” At the same time, computers will surely become a central part of the school in the future.

According to The Age, the distance learning will be popular and students will listen to teachers on computers. Going into classrooms on their computers, students will study at any time, which is very easy for them. However, it is necessary for students to go to the actual school in order to develop some social skills.

Seashore Primary School is an imaginary school in the future created by the Education Department of Australia. At this school, all the teachers and students have laptop computers. Teachers check messages and call students back with a special telephone system and students use telephones to search for information or speak to their teachers who give their lessons. Besides, all the lessons are related to all sorts of subjects and all the students have their own learning plans created by teachers.

As one headmaster says, a laptop computer is a student’s library, data storage(数据存储) device as well as the bridge to a wider world. Technology has changed the emphasis of future learning. Thus, we’ll pay more attention to the learning of kids rather than the teaching.

3 . Once upon a time, there was a man who believed he could see the future through the stars. He called himself an astrologer and got used to _______ at the sky all night. He was always busy worrying about the _______ . The _______ often came to him, hoping to know what their future would be like.

One evening he was _______ on the main road outside the village. His eyes were fixed on the stars. He thought he saw that the end of the world was near. He was concentrated on thinking about the future. When he looked up at the stars, he walked without looking _______ . Suddenly he fell into a ditch (沟渠) full of _______ and water.

He was _______ in the muddy water, and _______ trying to climb out. Being unable to crawl (爬行) out and fearing for his _______ , he started to shout for help and his ________ soon brought the villagers running towards him.

As they pulled him out of the mud, one of them said, “You ________ to read the future in the stars, and yet you ________ to see what is at your feet! This may teach you to pay more attention to what is right in front of you, and let the future take care of itself.”

“What use is it,” said another, “to read the stars, when you can’t see what’s right here on the earth?”

We all want our future to be ________ and happy. However, the time doesn’t stop for anyone. There is always a tomorrow to look forward to and ________ , but you can’t go back to yesterday. So, maintain your ________ life while you work for a better tomorrow.

5G is developing, but most of us aren't really sure what it is or the reason     1     we need it. A big part of the reason is that 5G means more than one thing. If you ask different people, you     2    (provide) with different answers.

Experts believe that 4G is on     3     way out. In 2020, the U.K. is expected to use 5G. At present, it is unknown exactly what influence 5G will have on people's life but it is widely thought that 5G will     4     (definite) be faster than any generation of networks we have used previously.

Work will likely become much easier as 5G will allow quicker downloads and a better ability to work online even if there is no wi-fi connection. With the     5     (develop) of 5G, driverless cars will be able to communicate     6     other vehicles, which can reduce road accidents by about 10%, One of the most     7     (impress) things will be that people can see which seats on a train are accessible to     8     (they) when it arrives at the station.     9     (get) around the world will also be more convenient.

A number of     10     (company) are now working on bringing 5G to the market. It remains to be seen how much of the country 5G will cover and whether everyone will be able to benefit from it.

8 . On paper, hydrogen（H2）looks like a dream fuel. Coal, oil, and natural gas produce carbon dioxide, which warms the earth when burned, Hydrogen produces pure water. Hydrogen packs more energy into less space than a battery（but certainly less than petrol）. Also, empty tanks（燃料箱）can be refilled with hydrogen much faster than refilling empty batteries with electricity.

While in practice, things are trickier. Storing a meaningful amount of hydrogen gas requires pressing it several hundred-fold. Changing it into the liquid form is another option, but it should be cooled to-253C. Both processes require a heavy and strong tank. While a 700 bar tank is acceptable for a city bus or a truck, adapting it for use in small vehicles is very difficult because the pressure during refilling would be too great.

The solution? Powerpaste.

A German team of researchers, led by Marcus Vogt, have come up with an interesting "powerpaste", which can store hydrogen energy at atmospheric pressure, ready for release when needed. It is so named because it comes in tubes and looks like toothpaste（牙膏）, not in its traditional form of gas.

The main ingredient（原料）of the paste is magnesium hydride, a substance that reacts with water to form hydrogen. The escaped hydrogen can then be directed into a fuel cell, where it reacts with oxygen from the air to produce electric power.

Refueling is very simple, as instead of going to a filling station, drivers and riders can simply replace an empty tube with a new one and refill the water tank.

Given that powerpaste only begins to break down at temperatures of around 250℃ it remains safe even when a vehicle stands in the baking sun for hours.

However, we will have to be patient. Just because researchers have succeeded in developing a new fueling way does not mean that we can expect to see such vehicles on the road anytime soon. It will indeed be several years before this concept is turned into reality.

10 . Welcome to your future life!

You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people at your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of you look the same age!

You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells(细胞) in your body. The particles can be programmed to change your clothes’ color or pattern(样式).

You walk into the kitchen. You pick up the milk, but a voice says,“ You shouldn’t drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip.

It’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology” is all around you.

So will all these things come true? “For new technology to succeed,” says scientist

Andrew Zolli ,“it has to be so much better that it replaces what we have already.” The Internet is one example—what will be the next?
