2 . If you watch the sky for about an hour after the sun goes down,you may see some “moving stars”. But they are not really stars. They are man-made satellites. And the biggest of all is the International Space Station (ISS). From May to July is the best season to watch the ISS flying over the earth. And people can see it with their eyes during the time.
The scientists want to live on the ISS. They think that the best way to learn more about space is to live there.
When the space station is finished, it will be like a city in space. People will stay and study there with many of the things they have at home. Laboratories, living rooms and power stations are being built. The ISS is the most expensive program. Billions of dollars are spent on it every year.
Scientists hope that the ISS will be a stepping-stone for future exploration. “The ISS will be more useful some day. The ISS will help us understand the human body better, explore space and study the earth. It can help us make life on the earth better.” said Kathryn Clark, an ISS scientist.
Sixteen countries are part of the space program: the US, Russia, Canada, Japan, Brazil, and 11 European countries. China isn’t an ISS country, but it has helped with some of the experiments. In 2003, China sent some rice up to the ISS to find out what space would do to it.

China’s first artificial intelligence (AI, 人工智能) theme park opened to the public in November, 2018, after 10 months’ renovation(整修) of Haidian Park in Beijing. It is free to the public, allowing anyone to check out the park’s AI devices(设备), Xinhua reported.
Haidian Park covers about 34 hectares near the 4th Ring Road. It received about 1.2 million tourists in 2017. The district government of Haidian and the Internet company Baidu signed an agreement in January to jointly explore the “smart city” building. Haidian Park was chosen to run the pilot programme.
Visitors can travel around the park on driverless buses. There is also a running road that has cameras at its starting point, midway point, and finishing point that can record health data when you run on it. The data include travel distance, time, heartbeat and pulse(脉搏). You can collect this data by following the park’s official WeChat account.
You can learn t’ai chi by practising in front of a screen in the park. Cameras record your movements and compare them with the teacher’s to help you improve.
“It’s hard to imagine that elderly people like me could have such a technological experience,” Mrs He told People’s Daily. Her husband made a video while she was practising t’ai chi.
In recent years, many Chinese hightech companies have set foot in the AI industry. The central government stressed that it would make the development of the country’s new generation of artificial intelligence become better and moresuccessful.

6 . In the future, “smart clothes” are used not only for covering your body, but for many other kinds of uses. Some kinds of “smart clothes” have come into the market.
An English company has developed a cloth keyboard. You can put it onto your pants. You can control you computer with it easily anywhere. If it gets dirty, the keyboard can be washed and even ironed.
As the technology improves, “smart clothes” will get much smarter. Researchers are developing such a kind of clothes. They may show your body temperature and heat you up before you feel cold. Other smart clothes to wear are special medical ones. They can tell the doctor when you are in danger. Jackets with GPS technology can keep you from getting lost. New smart clothes will even be able to adjust to your moods.
People have begun to love the idea. Maybe “smart clothes” will one day be common on Paris’ streets — and even in your own home.

The World Future Society(世界未来学会) writes reports about how modern technology(现代科技) will change our lives. People People may live for up to 120 years and use new technology to help them look young. The number of people over a hundred years old could go from 135, 000 today to 2.2 million by 2050. Money Worldwide e-business will become even more successful with online shops. They will sell special products(产品) for each person and the products will be brought to their houses the next day. Environment In the future wind and sun energy could become much cheaper and many more countries could use it. This would be very useful in poor countries. The air in big cities would also become much cleaner and healthier as a result. Society and culture The Internet will help to create more worldwide friendships. Families may spend more time together as people will be able to do 24-hour online banking and shopping. |

9 . Researchers said they had found out that there was once an ancient fresh water lake on Mars that might have been able to support life.
A team of researchers from the US Curiosity Rover Mission, analyzed (分析) some mudstone and fine-grained sediment (细粒沉积物) which can tell us that there was at least one lake around 3.6 billion years ago.
The team said their analysis showed that the lake was calm and likely had fresh water, including key biological elements, such as carbon, hydrogen, oxygen, nitrogen and sulphur (硫磺). Theoretically, such a lake would provide perfect conditions for simple living things.
The findings were published in the US Journal Science and presented at the American Geophysical Union’s fall meeting in San Francisco. “It is important to note that we have not found signs of ancient life on Mars. What we have found is that there once existed a lake on its surface which might make it possible for some simple living things to live billions of years ago,” Professor Sanjeev Gupta said in a statement. Gupta described the new research as “a huge positive step” for the exploration of Mars.
In previous studies, scientists found evidence of water on Mars’ surface in other rocks. However, the new research provides the strongest evidence yet that Mars could have been habitable enough for life to continue.

10 . Man has invented four kinds of satellites. The first kind of satellites studies the geography of the earth. They are used to make maps. They also help countries to see where they may find oil or gold.
The second kind of satellites is used to guide ships and planes. A ship or a plane can send a message to the satellite, and the satellite can find out where the ship or the plane is.
The third kind studies the weather. These satellites watch clouds and strong winds moving across the earth. They warn countries to make preparations when very bad weather is coming.
The last kind is used for communication. Telephone calls between countries can be sent by these satellites. Some can carry hundreds of calls at the same time. The call is sent to the satellite, then the satellite sends it to a station in the country and this country is being phoned. These satellites also carry pictures; they can receive and send about eight programmes at a time.
