Running is becoming popular these days. Many of us run for our health. Doctors say many of the health problems come from these bad habits: eating too much, drinking too much, smoking too much and not having enough exercise. Doctors tell us, "Eat less, don't smoke, and exercise more."
Running is good exercise because it helps build a strong heart. It also helps most people lose weight. One 68-year-old woman runs three times a week. She runs to lose weight. "I love to eat," she says.
Running is good for our health in other ways, too. Many runners say running makes colds and other small health problems go away. "Running is my doctor," says one man.
Running can also help people to relax. So today men and women of all ages enjoy running

A rabbit is running into its hole. You may ask, “What happened?”
Well, when a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs. When other rabbits see this tail moving up and down, they run too. They know that there is 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 bee found some food, it goes back to his home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is.
Some animals say things by making sounds. A dog barks, for example, when a stranger
comes near. A cat purrs (发出呼噜呼噜的声音)when pleased. Some birds make several different sounds, each with its own meaning.
But human beings have something that no animals have –-- a large number of words about things, actions, feelings or ideas. We are able to give each other information, to tell or inform other people what is in our mind or how we feel. By writing words down we can remind ourselves of the things what have happened, or send messages to people far away. No animals can do this. No animals has the wonderful power of language.
No one knows how man learned to make words. Somehow he learned to make them. As centuries went by, he made more and more new words. This is what we mean by language.  People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. A very large English dictionary, for example,  contains four or five hundred thousand words. But we do not know all these. The words we know are called vocabulary. We should try to make our vocabulary larger. Read as many books as possible. When we meet a new word, look it up in the dictionary. A dictionary is the Most useful book.

It is 40 meters long and 6 meters wide. This must be the biggest bus you have ever seen. It can carry 1,200 to 1,400 people.
It is China’s new Super Bus. It went for a test run in Beijing. Some other cities are also interested in running the Super Bus. They hope it can solve traffic problems.
The Super Bus runs along *fixed tracks. The bus sits on top of two2.2-meter-tall legs. The legs have wheels at one end. Small cars can drive under the bus, so the Super Bus does not take up road space.
The bus runs on *electricity and *solar power. It can travel up to 60 km every hour. Its creator, Song Youzhou, says it can reduce a lot of traffic *jams.
The Super Bus can do the work of 40 buses. In that way,  it can save 860 tons of *fuel every year, according to Song.
‘ Building a Super Bus and its track costs less than building subways. Subways are nearly ten times more expensive to build. ’ Song says.
Some people worry that the Super Bus may not be safe. However, Song says there’s no need to worry about that. The Super Bus has *laser *scanners between its legs. The scanners make sure the cars keep a safe distance.
