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 or

| Personnel changes at the International
Monetary Fund and proposals for changing the fund have been reported lately.
After a lengthy public debate, the leading countries settled on another German,
Horst Kohler, to replace Michel Camdessus as the IMF’s managing director.
Unfortunately, the circus-like process began to resemble an affirmative-action
procedure when it became clear that a particular nationality--German--was a
prerequisite for the job. Calls for changes at the IMF came in the report from Congress’ International Financial Institution Advisory Commission, led by Allan H. Meltzer. (I was a witness before the commission on issues related to inequality.) The Meltzer Commission’s report surprised me by not advocating abolition of the IMF. The report said: "The commission did not join the council of despair calling fo A. Horst Kohler works as the managing director. B. It is abolished. C. Michel continues his leading over IMF. D.
