Astronomers recently announced they had observed a faraway galaxy that may have at its center two black holes, very close together. Based on their observations, the stargazers suspect one of the black holes has more mass than the other. The more mass something has, the stronger its gravitational force, so a larger black hole has a stronger gravitational attraction. The smaller black hole orbits(作轨道运行) the larger black hole, just as the earth orbits the sun. The biggest galaxies in the universe form when two smaller galaxies collide(碰撞). If two galaxies merge(合并), then all of their stars start orbiting a common center. The black holes at the galaxies’ centers should come together, too. Galaxies are colliding all the time, so we should be able to find lots of black hole pairs. But that’s easier said than done—astronomers rarely find these in deep space. To find a black hole is complicated. A black hole doesn’t produce any light, so how can you find one in space? Astronomers think when something (like dust) falls into a giant black hole, a jet of radiation, a form of energy, may stream away. If this radiation is strong enough, it forms a quasar(类星体). The Arizona astronomers looked at more than 17,000 quasars and finally found a galaxy that may have a double black hole at its heart. Though the finding of their research is still unconfirmed, and they may be mistaken, the truth will be revealed in the future. 63. Which of the following is TRUE about black holes? A. A black hole is a region in galaxies with nothing in it, even a bunch of light. B. Black holes are used by astronomers to study how quasars come into being. C. When different galaxies meet in space, the black holes become bigger and bigger D. Some scientists think there’s one black hole in a galaxy, but others think there’re two. 64. From the second paragraph we can infer that ________. A. a larger black hole pushes a smaller black hole away B. a larger black hole pulls a smaller black hole toward it C. the places of black holes are fixed, so we can see them clearly D. a smaller black hole moves around a larger one because of radiation 65. According to the passage, astronomers think that there should be many black hole pairs because____________. A. a black hole can produce light B. black holes can attract one another C. different black hole pairs come into being with the meeting of galaxies. D. a big black hole can usually be divided into two small black holes 第四部分：任务型阅读(共10小题;每小题1分，满分10分) 请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。 注意：每个空格只填1个单词。请将答案写在答题纸上相应题号的横线上。 The New York City Marathon was started by a man named Fred Lebow. It began in 1970 as a small, unimportant race. Only 127 local people ran, and just 55 of them finished. They ran around Central Park four times. Few people watched them run. However, over the years the marathon grew and became more popular. Today people come from all over the world to run in the marathon. Runners must be at least 18 years old. In fact, the oldest runner was an 89-year-old man. Recently, more than 27,000 people ran in the New York City Marathon. Large crowds cheered the runners and offered them cold drinks and encouragement. The course of the marathon has changed. Instead of running around Central Park, the runners go through the five districts of New York City: Queens, Brooklyn, Manhattan, the Bronx ,and Staten Island. The marathon begins at the base of the Verrazano Narrows Bridge in Staten Island. The runners go across the bridge into Brooklyn. Then they go up through Queens and into the Bronx. The marathon finishes in Central Park in Manhattan. The complete course is 26.2 miles, and takes the best runners less than 3 hours. Although it has changed since 1970, the New York City Marathon is always exciting. Through the years, many unusual events have happened during the marathon. For example, Pat Tuz and John Weibaker got married a few minutes before the race. Then they ran the race with their party members. Some people run the whole race alone. In the fall of 1992, Fred Lebow, the founder of the New York City Marathon, slowly ran his last race. He was very ill with cancer, but he did not want to stop running. In October 1994, Fred died. However, the New York City Marathon, and all its excitement, will continue for many years to come.
