         Antarctica is the continent which is the most     1     area of land on the
Earth and is mostly covered     2      ice. This is    3      of the driest and     4  
 in the world. But people from all over the world come to     5    there. Near
the South Pole, three   6      people live together in a place     7    Amunsen-
Scott Station.
         The station has libraries, cinemas, shops, sports rooms, canteens and laboratories (实验室). There is
electricity (电), and they have     8     the system that they use to have a conversation (交谈)    9     someone in
another place. And they have     10     electronic machines that stores information and uses programs to help the
m find, organize, or change the information.
         But the people here     11    travel by car, or train, or bus, because there aren't any roads or railways near
the station. They travel by ship, helicopter, plane, or snow tractor, or    12      dogs.
         There aren't    13      trees or flowers there, but there are hundreds of different birds and other animals.
          Most of the people here are    14      . They study plant and animal life
and how ice moves. The ice can tell us about changes in climate. Ray Kingman
is an expert at Amundsen-Scott Station, telling us on the phone, "This is my
second year here. It's a very interesting and beautiful place, but life is very
hard     15     . In the summer we can go swimming in hot pools of water.
We welcome newcomers here for further study of the continent!"
