The polar bear(北极熊) is white. We call it polar bear because it lives inside the Arctic Circle(北极圈) near the North Pole. There are no polar bears at the South Pole.

The polar bear lives in the world of snow and ice. At the North Pole, there is only snow, ice and water. There is not any land. It's not easy to see the polar bear in the snow because its fur is white. It has a very thick(厚的) coat of hair because it is very cold in the Arctic Circle.

A polar bear can be three metres long and weigh 450 kilograms. It has very wide feet, and it can stand up on its back legs. It can swim 120 kilometres out into the water at a time. It catches(捕获) fish and sea animals for food. It hides when it is frightened(受惊吓的). Some people kill the polar bear for its beautiful white coat. The governments of Canada and the USA say that no one can kill polar bears in the two countries now. They hope these beautiful animals won't die out.
