英语翻译
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 of one particular comet was a very difficult mathematical problem.He could not figure it out.Neither could other scientists who dealt with such problem.However,Halley had a friend named Isaac Newton,who was a brilliant mathematician.Newton thoughthe had already worked out that problem,but he could not find the papers on which he had done it.He toldHalley that the orbit of a comet had the shape of an ellipse (椭圆形).Then Halley set to work.He figured out (解决,计算出) the orbjts of some of the comets that had beenobserved by scientists.He made a surprising discovery.The comets that had 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 about it,the more he thought that there had not been three different comets,as people thought.He decided that they had simply seen the same comet three times.The comet had gone away and had come backagain.It was an astonishing idea!Halley felt certain enough to make a prediction (预言) of what would happen in the future.He decided that this comet would appear in the year 1758.There were 53 years to go before Halley's prediction could be tested.In 1758 the comet appeared in the sky.Halley did not see it,for he had died some years before.Ever sincethen that comet had been called Halley's comet,in his honour.

这篇短文是关于哈雷彗星名字的来历,跟一位科学家有关
埃德蒙哈雷是一位200年以前的英国科学家.他也研究其他科学家曾研究过的彗星.计算一个彗星的轨道是一个特别困难的数学问题,他和其他的科学家一样不能解决这个问题.但是哈雷的朋友艾萨克牛顿是一个优秀的数学家.牛顿认为他自己已经解决了这个问题但找不到他曾用来计算的记录文件了.他告诉哈雷彗星的轨道式椭圆型的,然后哈雷据此计算出了一些彗星的轨道.他发现了一个惊人的现象,这些1531,1607,和 1682出现的彗星都有一个相同的轨道,但他们出现的时间相隔了75到76年.哈雷觉得很奇怪,3个不同的彗星有一个相同的轨道,哈雷思考的越深入,越觉得这些不像人们想的那样有三个不同的轨道.他毅然相信人们三次看到的是同一彗星,它走了又回来了.这是一个惊人的想法,哈雷非常确信的做了一个预言：1758年彗星还会出现.这个预言是在彗星再次出现前的53年.
1758年彗星出现在了天空中,但哈雷并没有看到,因为他在此数年前已经逝世了.从此,人们为了纪念他,称这颗彗星为哈雷彗星.
