Nearly all our food comes from the soil. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter (粪) from animals also falls on it.
All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers (化肥) are also very useful. The same crop (庄稼) should not be grown in the same place every year; it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.
【小题1】What would happen first without plants?

A．People would have more crops.	B．Animals would die.
C．There would be more food.	D．There would be less soil.

In the summer of 1978 an English farmer named Lan Stevens was driving his tractor through a field of wheat 1 he discovered something strange.

Some of his wheat was lying flat on the ground. The 2 wheat formed a circle about six meters 3 . Around this circle were four smaller circles of flattened wheat. The five circles were in a formation 4 five dots on dice.

Three years later a farmer who lived nearby discovered similar circles in one of his fields. These circles were 5 —nearly 15 meters across.

That same year, yet another English farmer discovered three circles of flattened wheat on his land—one large circle 6 two small circles.

During the 7 years, farmers in England found the mysterious circles in their fields more and more often. In 1987 they discovered 50 circles; in 1988, 98 circles; and in 1989, 270 circles.

The circles are called “crop circles” because they appear in fields of grain—usually wheat or corn.

The grain in the circles lies flat 8 but is never broken: it continues to grow horizontal, and farmers can later 9 it.

Many people believe that beings from outer space are making the circles. Some think that the beings are trying to communicate 10 us from far away and that the crop circles are messages from them.

11 believe that the beings have actually landed on earth and that the circles are 12 left by their spaceships. Several times people reported 13 strange flying objects near fields where crop circles later appeared.

Scientists who have studied the crop circles say they're not sure what 14 them. They 15 several theories.

For example, some scientists say that “microburst” of wind create the circles. A microburst is a 16 rush of cool air—the same downward rush of air that sometimes causes an airplane to crash.

Other scientists say that forces 17 the earth cause the circles to appear.

Experts from 18 have studied them. What do the experts 19 the crop circles? They say what Lan Stevens said: “They don't know how 20 these things.”
