阅读理解。
     If you watch the sky for about an hour after the sun goes down, you may see some "moving stars". But
  they're not really stars. They're 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.
     The ISS is the biggest satellite (人造卫星) and 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 expensive space program. Billions of dollars are being spent on it every year.
     Scientists hope that the ISS will be a stepping stone for future space exploration (探测). "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 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.
