Chinese space lover Wang Yuan has been chosen as one of the volunteers for the Mars-500 test project. 1. Another five volunteers are all space lovers. They are three Russians, an Italy-Colombian and a Frenchman. They will feel what it's like to travel to Mars without leaving the earth. During the whole process (过程), they are locked up for one and a half years under the condition which is similar to the red planet. So the experiment is called Mars-500.
2.Although the volunteers won’t leave the building, they will feel as if (好像) they are on a real trip to Mars. The most difficult thing is that they will be separated from the people outside. 3.
That will be hard. When reporters asked what they would miss most during the 500-day special life, Charles from France said, “For me, it will be mainly my family, the sun and fresh air.”
The main task is to study “Man and Environment”. It will care about the astronauts’ physical effects and the experience of staying there.
4.So they will have to make decisions by themselves and then report to the earth, and the earth will tell them whether they do the right thing or not.

If you look at the sky one night and see something moving and shining that you have never seen before, it might be a comet (彗星).
A comet sometimes looks like a star. Like a planet, a comet has no light of its own. It shines from the sunlight it reflects (反射). Like the earth a comet goes around the sun, but on a much longer path than the earth travels.
If a comet isn’t a star, what is it then?
Some scientists think that a large part of a comet is water frozen (冻) into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock. When sunshine melts (融化) the ice in the comet, great clouds of gas go trailing after it. These clouds, together with the dust, form a long tail.
Many people have seen a comet. However, no one knows how many comets there are. There may be millions of comets, but only a few come close enough for us to see.
An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky. Some comets move out of our sight and never come back. Others keep coming back at regular times. A big comet that keeps coming back was named after Halley comet, because the last time it came close to the sun and the earth was in the year 1986. Then people all over the world were outside at night to look at it. You will probably be able to see Halley’s comet when it comes near the earth again.

A new report shows what life might be like in 100 years from now. It describes skyscrapers that are much taller than today’s buildings, underwater “bubble” cities and holidays in space. The report is from a company. It asked experts (专家) on space and architecture, as well as city planners, to give their ideas on the life in 2116. They said the way we live, work and play will be totally different to how we do these things today. The experts used the Internet as an example. They said that 25 years ago, people could not imagine how the Internet and smartphones would change our lives. The Internet has completely changed the way we communicate, learn and do daily things. The experts said the changes in the next century would be even more unbelievable.
Researchers questioned 2,000 adults about the prediction (预言) they thought were most likely (很可能的) to happen in the future. They predicted that in the future, few people will go to an office but will work from home and have work meetings online. People will have highly developed 3-D printers that will let you download (下载) a design for furniture or a food recipe and then “print” the sofa, table or pizza at home. There will also be less need for visits to the doctor. We will all have a home health instrument that will tell us what the problem is and give us treatment. We will also be going into space for holidays and to get resources that we have used up on Earth. A prediction that is missing is whether people will still need to study English.

Scientists have always wanted to know more about the other worlds in space.

The moon is about three hundred and eighty-four thousand kilometers away from the earth. A plane can not fly to the moon because the air reaches only 240 kilometers. Then there is no air. But something can fly even when there is no air. That is a rocket.
How does a rocket fly? There is gas in the rocket. When the gas is made very hot inside the rocket, it will rush out of the end of the rocket, so it can make the rocket fly up into the sky.
Rockets can fly far out into space. Rockets with men in them have already reached the moon. Some rockets without men in them have flown to other planets much farther away than the moon. One day rockets may be able to go to any place.
