Mobile phones are one of the most useful inventions of the last 50 years， but not everything that is said about them is good． Mobiles are often believed to be the cause of a number of things from poor eyesight and headaches to house fires． There's even one theory that mobile phones should be responsible for the disappearance of bees!
The theory is that the radiation （辐射） given off by mobile phones does great harm to bees， navigation systems （导航系统）． Bees have a built﹣in system a bit like GPS and this helps them find their way back to their hives．But recently， thousands of bees have failed to find their way home． It is believed they are dying far from their hives．
The problem was first noticed by beekeepers in America and is a lot more serious than it at first seems． The important thing about bees is that most of the crops in many countries of the world are pollinated by them． Without bees， the crops can't continue to grow． Many beekeepers in Europe have reported losing between 50 and 70 percent of their bees． Jim Piper， a London beekeeper， said to the reporter， "My business is becoming worse． Twenty nine of my forty hives are now empty．"
Nobody knows for sure whether the theory is true or not， but it's a fact that bees are disappearing in very large numbers． And we can't manage without them．Einstein said that if all our bees disappeared，man would only live for four more years! If the mobile phone theory is correct， we need to do something about it right now﹣before it's too late．

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. For me, I will not wait. I will take the bus more often from now on. Join me and save the polar bears, and of course, the tigers, the giant pandas and...

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.
