[单项选择]They are giant geometric patterns, which appear over-night in a field of crops. Many people believe that they are made by aliens. Others call them hoaxes. " Crop circle", as the mysterious patterns are called, became a hot phrase this month.
A strange pattern 360 feet (110 meters) in diameter was discovered earlier this month in a wheat field in Oxfordshire, England. It’s believed to be the world’s first three-dimensional crop circle. The giant crop circle gives an impression of looking down on skyscrapers from above. The design’s discovery immediately generated a new tide of public interest in this mysterious phenomenon.

SOCIAL BEHAVIOR IN ANIMALS

1 Social behavior is communication that permits a group of animals of the same species to become organized cooperatively. Social behavior includes any interaction that is a consequence of one animal’s response to another of its own species, such as an individual fighting to defend a territory. However, not all aggregations of animals are social. Clusters of moths attracted to a light at night or trout gathering in the coolest pool of a stream are groupings of animals responding to environmental signals. Social aggregations, on the other hand, depend on signals from the animals themselves, which stay together and do things together by influencing one another.
