         If you watch the sky about an hour after the sun goes down, you may see some "moving stars". But
    they're not real stars. They are man-made satellites. And the biggest of all is the International Space Station
    (ISS 国际空间站).
         From now until July is the best season to watch the ISS flying over the earth, and people can see it just
    with their eyes. The ISS is the biggest man-made satellite because scientists want to live on it. 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 ambitious (雄心勃勃) and expensive space program ever. Billions of dollars are being spent
    on it every year.
         Scientists hope that the ISS will be a stepping-stone (垫脚石) for future space exploration."The ISS will
    help us better understand the human body, explore space and study the earth. It can help us make life on the
    earth better," said Kathryn Clark, an ISS scientist.
         China is not an ISS country, but it has helped with some of the experiments. China sent some rice up to
    the ISS to find out what space would do to it.
         The ISS is not finished yet. More than 100 parts need to be put on. Scientists hope it will be finished as
    soon as possible. After it's finished, more than 90% 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.
    1. The ISS is _______.
    A. a world power station
    B. a man-made satellite
    C. an outer space moving star
    D. a stepping-stone to the sun
    2. You can watch the International Space Station with your eyes _______.
    A. an hour before sunset
    B. while flying on the earth
    C. in a special room
    D. from now till July
    3. The ISS is in fact regarded as _______ for space exploration.
    A. a laboratory
    B. a city
    C. a living room
    D. a museum
    4. The passage tells us that _______.
    A. China belongs to the ISS
    B. to build the ISS will cost less in the future
    C. China did some research on wheat through the ISS
    D. the best way to learn more about space is to live on the ISS

         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
