     Near the North Pole (北极) there are only two seasons: winter and summer. In winter, nights are

long. For more than two months you can't see the sun,even at noon. In summer, days are long. For more

than two months the sun never sets and there is no night at all. The temperature (温度) is very low near

the North Pole. Even in summer the temperature is below 0℃. So people there wear warm clothes all

year round. They make their clothing from the skins of animals. From the skins they also make coats,

hats and even boots.

       In the cold climate, plants cannot grow. So the people have to build their houses with skins, earth,

stone or snow. When they go out to hunt something, they live in tents of skins. When they move, they

take their tents with them. Sometimes, they build houses of snow. Now don't think that these houses

must be cold. In fact, they are very warm and safe.
