The Antarctica is actually a desert.
The Antarctica is all ice all the year. The warmest temperature ever recorded there is zero at the South Pole. Explorers(探险家) used to think that a place so cold would have a heavy snowfall. But less than ten inches of snowfalls each year. That is less than half an inch of water. Ten times that much moisture(水分) falls in parts of the Sahara.
The little snow that falls in Antarctica never melts(融化). It continues to pile up deeper and deeper year after year and century after century. When the snow gets to be about eighty feet deep, it is turned to ice by the weight of the snow above it.

Computers Help Fire Fighters
In Kansas City, Missouri, a computer helps fire fighters. The computer contains information about every one of the 35000 street addresses in the city. When fire fighters answer a call, the computer will give them important about the burning building, its position and almost all the ways of helping fire fighters with the problems facing them. For example, it can give medical information about invalids living in a burning building. With this information, the fire fighters can take special care to find these sick persons and carry them away quickly and safely.
The Kansas City computer system also keeps a medical record of each of the city’s 9000 fire fighters. The kind of information is especially useful when a hospital can treat the injured. With this information, doctors at the hospital can treat the injured fire fighters more quickly and easily.
