25、Antarctica is the highest continent on Earth，with the coldest temperatures and the most wind．People have never wanted to live there because it is so cold．The lowest temperature once was -89.2℃! But now scientists from all over the world come to study the ice．They want to learn more about the Earth's history．

     Some scientists live on Antarctica for part of the year．But they don't usually stay there for more than six months．Why? There are six months of light and six months of darkness．

      Antarctica usually has a good deal of fine weather without any wind at all．The strong winds are usually only in some parts of it.  It is also interesting to learn that it isn't very wet there．There is very little snow or rain．It snows on the ice in winter，but at other times Antarctica is dry，just like the Sahara Desert（撒哈拉沙漠）．

      In winter the sea around Antarctica freezes for thousands of kilometres．But scientists tell us that the Earth is getting warmer．So in future，there may be less ice in the Antarctic sea．When that happens, our weather will never be the same again．
