摘要：There are billions of stars in the sky -- but you can only see about 3,000 with your own eyes. Some people might say that it’s very difficult to learn the names of 3,000 stars. It isn’t! You can do it. Here is one way to start. Get a star map and begin to find your way through the sky. Many of the stars are in groups. The shapes of these groups never change. At different seasons, you will see different star groups. It is easy to learn the name of each group. Not all stars are the same. Some are bigger, some are smaller. Some look white, some look red, some look blue. You’ll soon see all the different ones.

     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.

    A. is really a big city in space

    A. building the ISS is only for scientists to live there

    C. people can see the Space Station at any time
    D. sixteen countries are members of the space program
3. The phrase "a stepping stone" probably means _____.
    A. 滑梯
    B. 巅峰
    C. 垫脚石
    D. 走廊
4. China sent some rice up to the ISS is probably to _____.
    A. be used as astronauts' food
    B. sell it to aliens
    C. do some science experiments
     D. make it grow better in space
