A young man was about to finish school. For a long time he had    36  to get a beautiful sports car. He knew his father could well    37  it, so he  told him that a sports car was all he wanted.
　　Then on the morning of his graduation（毕业）,he was called to his father’s room. His father told him how    38  he was to have such a fine son, and told him how   39  he loved him. He handed his son a beautiful gift box.  40 , the young man opened the box and found a lovely Bible（圣经）with his name on it. Angrily, he raised his   41  to his father and said, "With all your money you give me a Bible? " He then   42  out of the house, leaving the Bible.
　　Many years passed and the young man was very    43  in business, and had a beautiful home and a wonderful family.    44  that his father was very old, he thought perhaps he should go to see him. He had not seen him    45  that graduation day. Before he could go, he received a    46  telling him that his father had died. He had to go home immediately and take   47  of the things that his father left him.
　　When he began to search through his father’s important　papers, he saw the still new Bible,     48  as he had left　it years ago. He opened the Bible and began to   49   the pages. As he was reading, a car key with a tag（标牌）dropped from the back of the Bible. On the tag was the   50  of his graduation, and the words "PAID IN FULL". Sadness and regret（悔恨）filled his heart.

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.
