We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration (迁徙) is probably the migration of fish, which is called “salmon”(蛙鱼). This fish is born in fresh(淡的) water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of a kind of lobster (龙虾). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.

Fire can help people in many ways. But it can also be very harmful. Fire can make water hot and house warm, give light and cook food. But fire can burn (燃烧) things, too. It can make trees, houses, animals and other things catch fire (起火). If some people can't run away from fire, it can kill them. This happens in every country every year.
Sometimes big fire can burn forests. A month ago, a large forest fire broke out in Yunnan Province. It lasted nearly half a month. The forest in Heilongjiang Province and the grassland in Inner Mongolia caught fire in May, 2006. After more than ten days' fight, over 30,000 people and soldiers put out (扑灭) the fire at last.
Nobody knows clearly when people began to make fire, but there are many interesting stories about the first time a man or a woman started a fire. One story from Australia tells about a man who went to the sun and brought fire down a long time ago. Today people know how to make a fire with matches (火柴). Children sometimes like to play with them. But matches can be very dangerous. The match can burn a piece of paper and then it can burn a house. A small fire can become a big fire, and destroy many things. Fire kills many people every year. So you must be careful with fire.

Astronauts, people who fly into space, need special training. First they go to Houston, Texas. That is the home of the Johnson Space Centre. There they are tested to see how strong and smart they are.

One of the first tests is for the heart. The people walk or run, then the space doctors see how fast their hearts are beating.

Another important test is performed. In this test the person must curl(蜷曲)his body up in a ball. When he is in that position, he is put into a round cloth bag. The doctors give him no idea how long he will have to stay in the bag. If a spaceship broke down in space, the astronauts would get into bags like this. Then they would have to wait and curl up in darkness, until help could arrive. You can see that an astronaut must not be afraid of tight space or darkness.

After the tests, only the best people are chosen to start astronaut training in a training centre. The astronauts in training learn many other things. They learn how to jump out of a moving airplane. They learn to how to blow up a lifeboat and get into it while they are in the ocean. The astronauts also have to learn how to get lifted out of the ocean by helicopter(直升机). That may look fun, but it can be dangerous.

After they finish training, the astronauts continue to work. They stay in good shape by running and doing exercise. They read about their special jobs. In that way they can learn new facts about space travel.

Then the big day comes. The astronaut is told to go to work on a flight into space. The crew members(全体船员)get to know each other first. Then they can learn which job each will do.
