Visitors from space may have landed on our planet from time to time, maybe hundreds of times during the long, empty ages while Man was still a dream of the far future. Indeed, they could have landed on 90% of the earth as recently as two or three hundreds years ago, and we could never have heard of it. If one searches through old newspapers and records from some certain places, one can find many reports of strange events that could be some explanations about visiting from outer space. A writer, Charles Fort, has made a collection of UFO sightings in his book Lo! One is tempted(引诱) to believe them more than any modern reports, for the simple reason that they happened long before anyone had ever thought of space travel. Yet at the same time, one cannot take them too seriously, for before education on science was popular, even sightings of meteors(流星) and comets(彗星) made people believe the most unbelievable stories, as they still do today.
56.【小题1】According to the passage, visitors from outer space may have landed on the earth .A．long before man had dreamed of itB．long before there were human beingsC．in the last few hundred yearsD．after the space travel began57.【小题2】Which of the following statements is true according to the passage?A．Charles Fort sighted a lot of UFOs himself.B．All sightings of UFOs are believable.C．There may be living things on other planets.D．People have seen visitors from other planets everywhere.58.【小题3】According to the passage, .A．UFOs are only seen in recent yearsB．UFOs sightings are not newC．UFOs are just meteors and cometsD．UFOs are invented by peopleB

(答案→)B 解析：【小题1】细节题。文章的第一句话说道: Man was still a dream of the far future.意思是说人类还没产生，还只是未来的一个梦想。【小题2】细节推理题。通过排除，Charles Fort只是做了一个现象的收集；文章的最后一句话告诉我们也不要全信；文章中没有提到世界各地都看到了外星人。C选项是一个推测，是作者承认的。【小题3】主旨推理。根据文章，作者还是承认了外星人来访的可能性，所以选B。
