Question

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 flattened (變平的) 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 (點(diǎn)). 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 is 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 farmers had found. They could not do it. They couldn’t enter a field of grain without leaving tracks, and they couldn’t flatten the grain without breaking it.

Many people believe that beings from outer space are making the circles to communicate（交流）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 (墜毀). 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.

【解析】

試題分析:本文講述從1978年夏天，農(nóng)民發(fā)現(xiàn)田地里的莊稼被某種不知名的力量形成了許多的圓圈，多數(shù)以五點(diǎn)式存在，并就此現(xiàn)象展開論述。

1.】細(xì)節(jié)理解題。從文中第一段The flattened (變平的) 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 (點(diǎn)).可知農(nóng)民發(fā)現(xiàn)谷物變平，并且形成了直徑6米的圓圈，在這個(gè)周圍還有四個(gè)小的麥子形成的圓圈，整個(gè)莊稼就形成了五個(gè)圓形，故選B。

2. young people were making them as a joke, or farmers were making them to attract tourists.大概是年輕人是為了制作笑話而這樣做，或者是農(nóng)民為了用來吸引游客。故可推測(cè)出，人們認(rèn)為hoax是人們的愚蠢行為所做。故選A。

3. prove that the circles were a hoax, They couldn’t enter a field of grain without leaving tracks, and they couldn’t flatten the grain without breaking it.為了證明是人類所做成的這樣的圓，但是他們發(fā)現(xiàn)沒有離開的痕跡，他們就不能進(jìn)入田地，若不破壞它，就不能把莊稼變平。故可排除選項(xiàng)A，B，D。C沒有足跡，農(nóng)民不能離開，與文章照應(yīng)。故選C。
