Question

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.”
