Do you think of white when someone talks about a polar (北极)bear? In fact, the polar bear does not have white fur. It just appears to be white. Polar bears have a very good sense of smell. It helps them to find food. During summer, polar bears sleep longer, because they are able to find their food more easily at night. Usually, after a meal, polar bears have a short sleep. A polar bear can have 2-3 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 soon because of people. There are only 20,000 to 25,000 polar bears in the world. The ones that are left are trying to survive today. The number of polar bears is becoming smaller and smaller because of the loss of sea ice— polar bears mostly inhabit (居住于) the sea ice, not the land ice. This is happening because of global warming (全球气候变暖), pollution, hunting and so on.
Ordinary people don't care, but great people have the power and want to save tigers, fight for giant pandas and save polar bears. Ordinary people will wait, but great people will find a new world.

Animals, including insects, don't have a "language" like ours. They do not "talk" to each other in words and sentences. But if we watch them, we can see that they do have their ways of communicating with each other.
Can you see the rabbit's tail? When rabbits see this white tail moving up and down, they run away. They know that they are in danger. The rabbit has told them something without making a sound. It has given them a signal.
Many other animals use this kind of "language". When a cobra is angry, it raises its head and makes itself look fierce. This warns other animals. When a bee has found food, it goes back to its home. It cannot "tell" the other bees where the food is by speaking to them, but it does a little dance. This tells the bees where the food is.
Some animals "say" things by making sound. A dog barks, for example, when a stranger comes near. A cat purrs when it is pleased. Some birds make several different sounds, each with its own meaning. Sometimes we human beings speak in the same way. We make sound like "Oh" or "Ah" when we are frightened or pleased or when we drop something on our toes.
