In the summer of 1978 an English man named Steven was driving his tractor through a field of wheat when he discovered something strange. Some of his wheat was lying on the ground. The flattened wheat formed(形成)a circle about six meters across . Around this circle were four smaller circles of flattened wheat.

　 Three years later a farmer who lived nearby discovered almost the same circles in one of his fields. These circles were larger—nearly 15 meters across . That same year , another English farmer discovered three circles of flattened wheat on his land—one large circle between two small circles. During the following years, farmers in England found circles in their fields more and more often.

　 The circles are called “crop circles” because they usually appear in fields of wheat or corn. The wheat in the circles lies on the ground but is never broken; it keeps on growing, and the farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September. What causes the crop circles?

　 At first, people thought that some kids were making them as a joke, or that farmers were making them to attract tourists.(In fact, in 1991, two men said they made the circles themselves, but many scientists don’t believe them.) People tried to copy them: They tried to make circles exactly like the ones the farmers had found. They couldn’t do it. They couldn’t enter a field of wheat without leaving tracks, and they couldn’t flatten the wheat without breaking it.

　 Several times people reported seeing stranger objects near the fields where crop circles later appeared. Many people believe that these crop circles are the messages sent by living things from outer space(外层空间)or the marks left by their spaceships.

　 Scientists who have studied the crop circles try to find out what causes them. In the summer of 1990 some scientists spent three weeks in the part of England where many circles have appeared. They had all the latest high-tech equipment(最新高科技设备). The equipment—worth 1.8 million dollars—got nothing. But one night, as the scientists were watching a field, crop circles formed in the field behind them, which were quite different from the others. The scientists had neither seen nor heard anything.

　 When Steven discovered the crop circles on his land in 1978, he said, “It was just like something that had landed in the field from the air and gone back up again. I don’t know what to make of these things.”

　 Crop circles have appeared in England, Japan, the United States and Russia. Experts from all over the world have studied them, and they say what Steven said: They don’t know what to make of these things.

It is very important to be able to control yourself. Losing control may bring things that would never want to see. We can learn something from the following story.

Once a boy often made trouble. His mother gave him many nails （钉子）. She told him to hammer （锤，钉） one in the garden fence （栅栏）, every time he lost his patience （耐心） and fought with someone. The first day he hammered 27 nails. In the following weeks he learned how to control himself better and the number of the nails he hammered became smaller and smaller. He learned it was easier to control himself than to hammer nails.

The day finally came when he didn’t hammer any nails. He went to tell his mother about it. Then his mother told him to pull off a nail from the fence each time he didn’t lose his patience. After some days he told his mother that all the nails had been pulled off. Thus, she took him to the fence and said to him, “You’ve behaved（表现） well, but look at all the holes in the fence. The fence will never be again like it was before. When you fight with someone, you leave wounds（伤口） in him like these. The trouble may be over, but the wounds will always be there.”

So, learn to control yourself before you hammer the nails in the fence. Try not to leave any holes in your past.

    A man once had a dream about the Black Forest In Germany. In his dream he was walking in the forest when two men ran out and tried to throw him to the ground. He ran off as fast as he could, but they followed him. He reached a place where he saw two roads in front of him, one to the right and the other to the left. Which road should he take? He heard the two men behind him, getting nearer, and at the same time he heard a voice in his ear. It told him to go to the right, and he did so. He ran on and soon came to a small hotel. He was received there kindly and given a room, and he was saved from the two men. That was the dream.

    Twenty years later he was really in the Black Forest and, as happened in the dream long ago, two men ran out and tried to throw him down.
