    What is the sky? Where is it? How high is it? What lies above it?

    Is the sky blue? The sky has no colour. We know that there is air around the world. When planes fly，they need air to lift their wings(翅膀).Planes cannot fly very high because when they go higher，the air gets thinner. If we go up about l 200 kilometers from the earth，we find there is no air.

    Perhaps we can answer some of our questions now. The sky is space. In this space there is

    only the sun，the moon and all the stars.

         If you watch the sky about an hour after the sun goes down, you may see some "moving stars". But they
    aren't real stars. They're satellites, a machine that has been sent into space and goes around the Earth, moon,
    etc. And the biggest of all is the International Space Station (ISS).
         The ISS is the biggest satellite because scientists want to live on it. They think that the best way to learn
    more about space is to live there. The space shuttle Discovery has taken off from the Kennedy Space Center
    in Cape Canaveral, Florida several times and carried a few groups of astronauts to the International Space
    Station.
         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 space program ever. Millions and millions of dollars are being spent on it every year.
         Scientists hope that the ISS will be a stepping stone for future space exploration. "The ISS will help us
    better understand the human body, explore (know more about) space and study the earth. It can help us make
    life on the earth better," said Kathryn Clark, an ISS scientist.
         Sixteen countries are in the program: The US, Russia, Canada, Japan, Brazil and 11 European countries.
    China is not 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.
          Twenty Chinese students talked directly to an astronaut (spaceman) in the International Space Station (ISS)
    on radio in Nanjing, capital of east China's Jiangsu Province on Sunday, 2007. The 20 students, aged 10 to 19
    from Shanghai, Guangzhou and Nanjing, began talking to Clayton C. Anderson, a 48-year-old American
    astronaut at 18:50 p.m. at Nanjing No. 3 Middle School when the ISS was passing over Nanjing.
         After it's finished, more than 90 percnt of the world's population will be able to see the space station. So
    keep looking up, and maybe you'll see it get bigger and brighter.
    1. It seems that _______.
    A. we can probably see the ISS when the sun goes down
    B. some students from Nanjing have been to the ISS
    C. China is one of the members in the ISS group
    D. the ISS is still in the space but has stopped working
    2. Power stations" in the third paragraph infers _______.
    A. houses for people to live in, to study and do research work
    B. machines that go around the earth, the moon and some stars
    C. buildings where electricity is produced to supply a large area
    D. some countries which help send the ISS up into space
    3. —Why did the scientists send up the International Space Station (ISS)?
        —Because they _______.
    A. would send up most of the earth people to live there
    B. could talk with some Chinese school students
    C. hoped to travel to Mars and Venus some day
    D. wanted to live in space and do better research

    　　At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars．Our own planet, Earth, is becoming more and more crowed and polluted．Luckily, we can start again and build a better world on Mars．Here is what life could be like．

    　　First of all, transport shouldnbe much better．At present, our spaceships are too slow to carry large numbers of people to Mars－it takes months．However, by 2100, spaceship can travel at half the speed of ligh．It might take us two or three days to get to Mars!

    　　Secondly, humans need food, water and air to live．Scientists should be able to develop plants that can be grown on Mars．These plants will produce the food and air that we need．However, can these plants produce water for us? There is no answer now．

    　　There is a problem for us to live on Mars．Mars pukkss us much less than the Earth does．This will be dangerous because we could easily jump too high and fly slowly away into space．To prevent this, humans on Mars have to wear special shoes to make themselves heavier．

    　　Life on Mars will be better than that on Earth in many ways, People will have more space．Living in a large building with only 10 bedrooms is highly possible．Many people believe that robot will do most of our work, so we have more time for our hobbies．

    　　There will probably be no school on Mars．Every studetn will have a computer at home which is connected to the internet．They can study, do their homework and take exams in online schools．Each student will also have their own online teacher called“e-teacher”．

    　　However, in some ways, life on Mars may not be better than that on the earth today．Food will not be the same－meals will probably be in the form of pills and will not be as delicious as they are today, Also, space travel will make many people feel ill．The spaceship will travel fast but the journey to Mars will probably be very uncomfortable．
