Passage Three Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets (彗星) ,which other scientists had made. The orbit (轨道) of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems. However, Halley had a friend named Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse (椭圆形) . Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that appeared in the years 1531,1607, and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart. This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought abo

B. 1705

Passage 3 The English, as a race，have the reputation of being very different from all other nationalities. Including their close neighbors, the French, Belgians and Dutch. It is claimed that living on an island separated from the rest of Europe has much to do with it. Whatever the reasons it may be fairly stated that the Englishman has developed many attitudes and habits which distinguished him from other nationalities. Broadly speaking, the Englishman is a quiet, shy, reserved person who is fully relaxed only among people who knows very well. When he meets with strangers of foreigners, he often seems uneasy, even embarrassed. You have only to witness a commuter train any morning or evening to see the truth of this, serious-looking businesses and women sit reading their newspaper or dozing in a corner, no one speaks. In fact, to do so would seem most usual. An English wit, pretending to be giving advice to overseas visitors, once suggested, “on entering a railway com
