Some animals can easily find their way home after a long journey. How do they make it? Scientific research shows that they are born with certain unusual abilities for direction.

A certain kind of ants, for example, can count their steps to avoid getting lost. They can go as far as 110 metres and bring food home. These ants live in the open desert（沙漠）, so they have nothing to guide them along the way. It’s like someone walking six kilometres through a dark forest.

Some fish have an unbelievable sense of smell. They can smell even a single drop of their home water in a large sea area. Some sea birds have a similar ability. They are able to make a smell map of their flying area.

Some animals can sense the earth’s magnetic field（磁场）, while humans can’t. This magnetic field guides a certain kind of fish when they swim a long way to a place and then back. How can this kind of fish do that? It is still a mystery. Scientists have no good answers yet.

However, animals with such unusual abilities still have difficulty dealing with environmental changes caused by human activities. For example, many birds depend on stars for direction, but they get lost easily at night when city lights are kept on all night. To solve this problem, we can simply turn off some lights at night. Clearly, one small act of humans may mean a lot to animals.

Do you yawn（打哈欠）? There are about 20 reasons that scientists think are possible for yawning after research. They do not know exactly why yawning happens， but they do know many facts about yawning.

We know that everyone yawns in the same way. First you open your mouth slowly. Your mouth stays open for about five seconds. You take in a lot of air and then push it out. Then you

quickly close your mouth. We also know that yawning is contagious. When you see someone yawn， you yawn， too.

Many people say they yawn because they are bored or tired. That might be true. People do often yawn before they sleep and after they wake up. However, we know that people also yawn when they are excited or nervous. Olympic runners, for example, often yawn before a race. Why is that? In 2007, scientists found that a yawn can help a warm brain cool down.

Some scientists believe that yawning makes you notice things more quickly. When you yawn, you breathe deeply. You also stretch（强化） the muscles（肌肉） in your face, mouth, and neck. Your eardrums stretch, too. Maybe this helps you to be quicker to notice things.

In some countries, people think yawning is not nice. People put their hands over their mouths to cover a yawn. In other countries, people think yawning is healthy. They think that opening the mouth very big can let good things in. When they breathe out, they think that bad things go out of the body with the air.

Scientists do not spend much time studying yawning. That is probably because yawning does not hurt. It is just something we do.
