Life in the future will be different from life today. Between then and now many changes will happen. But what will the changes be?

The population is growing fast. There will be many people in the world and most of them will live longer than people live now.

 Computers will be much smaller and more useful，and there will be at least one in every home. And computer studies will be one of the important subjects in schools then. People will work fewer hours than they do now and they will have more free time for sports，watching TV and traveling. Traveling will be much cheaper and easier. And many more people will go to other countries for holidays.

 There will be changes in our food，too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep，so meat will be more expensive. Maybe no one will eat it every day. Instead，they will eat more fruits and vegetables. Maybe people will be healthier. Work in the future will be different，too. Robots will do dangerous and hard work. Because of this，many people will not have enough work to do. This will be a problem.

Dogs are friends of man. They work for us. They hunt with us. They also play with us. But a long time ago, all over the world, dogs were wild. Dogs can go back to the Stone Age. All dogs had the same ancestor (祖先). It is believed that this ancestor was much like a wolf. Other animals, like fox, also came from this ancestor. Thousands of years ago, man began to tame (使驯服) the wild dogs. When the dogs were tamed, they were trained well. The strong dogs then became working animals. They were trained to pull heavy loads (担子). They learned to keep watching over sheep and other animals. Working dogs could do other things, too. Some dogs were not strong. But they could help man hunt. Other dogs were best at pets. At first, there were only a few kinds of dogs. Today, there are more than 100 kinds.

　　We sometimes say the lion is “the king of the jungle(丛林)” because it is stronger and more dangerous than the other animals. It can run faster than most other animals and it can hunt(捕猎) the best. The lion is the highest animal in the land food chain. In the sea, the shark is at the top of the food chain. It can swim faster than most other sea animals. It can also use its big teeth to catch other sea animals and eat them.

　　What is at the top of the world's food chain? People are! We are not the biggest or fastest, but we are the cleverest. We could not run faster than most animals, so we invented cars and now we can move the fastest. We could not fight better than a lion, so we invented guns. Now we can hunt the best.

　　People's inventions are clever, but they can be dangerous, too. For example, many years ago in Inner Mongolia, people used guns to kill a lot of wild wolves. The wild wolves usually eat wild rabbits. But in recent(近来的) years, the number of wild rabbits is becoming bigger and bigger because the number of wild wolves is getting smaller and smaller. The wild rabbits competed(竞争) for the grass with the sheep and cows. Much of the grassland became desert because it was seriously destroyed(毁坏) by the rabbits.

　　Remember that we are a part of the food chain, so we are in danger, too! If we protect animals, we are protecting ourselves.
