【題目】 The polar bear (北極熊), in fact, does not have white fur. Usually after a meal, polar bears have a short sleep. A polar bear can have 2 to 3 babies at a time. They live with their mothers until they are about two and a half years old.

However, polar bears will die out (滅絕) soon because of people. There are only 20,000 to 25, 000 polar bears in the world. They are trying hard to survive today.
