阅读理解Inthesummerof1978anEnglishfarmer

阅读理解 In the summer of 1978 an English farmer was driving his tractor through a field of wheat when he discovered that some of his wheat was lying flat on the ground. The fattened (压平的) wheat formed a circle about six meters across. Around this circle were four smaller circles of flattened wheat. The five circles were in a formation like five dots. During the following years, farmers in England found the strange circles in their fields more and more often.The circles are called “crop circles” because they appear in the fields of grain - usually wheat or corn. The grain in the circles lies flat on the ground but never broken; it continues to grow, and 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.At first, people thought that the circles were a hoax. Probably young people were making them as a joke, or farmers were making them to attract tourists. To prove that the circles were a hoax, people tried to make circles exactly like the ones that farmer had found. They couldn’t do it. They couldn’t enter a field of grain without leaving tracks(痕迹), and they couldn’t flatten the grain without breaking it.Many people believe that beings from outer space are making the circle to communicate with us from far away and that the crop circles are messages from them.Scientists who have studied the crop circles suggested several possibilities. Some scientists say that a downward rush of wind leads to the formation of the circles - the same downward rush of air that sometimes causes an airplane to crash. Other scientists say that forces within the earth cause the circles to appear. There is one problem with all these scientific explanations: crop circles often appear in formations, like the five-dot formation. It is hard to believe that any natural force could form those.1.In the summer of 1978, an English farmer discovered in his field that __________.A.some of his wheat had been damagedB.his grain was growing up in circles.C.his grain was moved into several circlesD.some of his wheat had fallen onto the ground.2.According to the text, the underlined part “hoax” (in the 3rd paragraph) probably means __________.A.an attempt made to fool peopleB.a special way to plant cropsC.a research on the force of windsD.an experiment for the protection of crops.3.Which of the following may prove that the crop circles are not made by man?A.The farmer couldn’t step out of the field.B.The farmers couldn’t make the circles round.C.The farmers couldn’t leave without footprints.D.The farmers couldn’t keep the wheat straight up.4.A proper title for this passage is ___________.A.An Unsolved MysteryB.Strange Flying ObjectsC.The Power of Natural ForcesD.The discovery of Strange Circles

DACA解析文章讲述的是世界未解之谜之一的麦田怪圈的事情。1.事实细节题。根据第一段第二行可知。2.事实细节题。根据第三段At first, people thought that the circles were a hoax. Probably young people were making them as a joke可知。3.事实细节题。根据第三段第四行可知。4.主旨大意题。 文章讲的是麦田怪圈的事情，到目前为止还没有准确的解释。D错在strange circle表达不到位。其他两个选项偏离太远。

这个解释是对的
