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’s a long-awaited day for China. The navy now has its first aircraft carrier(航空母舰), Liaoning.
It’s a unique experience to get to know the life in the carrier. The carrier is just like a small city on the sea. It has all the functions for daily life. There are 4 words to sum up its characters: big, small, much and high. The carrier Liaoning is such a huge one that the total length of the whole corridor(过道)could reach over 20 kilometers. But the living space for the sailors(水手)is quite small. That’s because the carrier is designed for researching purposes, rather than comfortable living. Over 1,000 sailors, both men and women, are living onboard. They are arranged among over 3,000 tiny rooms below the deck. For visitors, it’s so easy to get lost. So the first thing the new sailors have to learn is their way around. The number of female sailors is much less than that of the males, taking about 5 percent of the total. But they play a key role in carrying out some special missions.
Also, you will be surprised by the high level of education of today’s sailors. The captain said that over 90 percent of the sailors are college graduates. Six hold Doctor’s Degrees and 45 have a Master’s. The whole team is young but vigorous. The complex work on the carrier requires high management abilities for the commanders onboard(在船上).
【小题1】Why do we visitors get lost easily inside the carrier?
A.Because they don’t have a map. |
B.Because the living space is quite small. |
C.Because there are too many corridors for rooms. |
D.Because the corridor inside the carrier is too long. |
A.The aircraft carrier is high since it is just like a small city. |
B.Most of the soldiers received good education. |
C.The expense(花费)to run a carrier is high. |
D.The high-level of their training. |
A.Liaoning is our country’s first aircraft carrier. |
B.Most of the sailors on the carrier are college graduates. |
C.There are far fewer women sailors than men sailors on the carrier. |
D.It is comfortable for the sailors to live in the carrier. |
