Russet Burbank potatoes were peeled, cut into shoestrings, and fried in its kitchens. As the chain expanded nationwide, in the mid-1960s, it sought to cut labor costs, reduce the num

For each q
31、uestion, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer. 51 “There is very little in my life that is more personal and more important to me than comets.“ The amateur astronomer David H. Levy told Terence Dickinson in an interview. “ Not just d
32、iscovering them but watching them, learning about them, writing about them, understanding what they do. It makes observing the sky intensely personal. I feel when I find a new comet that a door has been opened and I have seen a slightly new aspect of nature. There is this object in the solar system
33、that for a few minutes or a few hours only I know about. It is like trying to pry a secret out of nature. It is a very special feeling.“ Ever since he was a child, David Levy has been fascinated by the night sky and the wonders it reveals to devoted watchman. He developed a special feeling for comet
34、s before he reached his teens, though it was not until 1984 after nineteen years and more than nine hundred hours of combing the sky in search of them that he discovered his first one, from a small observatory that he had built in his backyard. Since then, he has discovered or co-discovered twenty m
35、ore, making him one of the worlds most important comet hunters. His most celebrated find is periodic comet Shoemaker Levy 9, which he made with the husband-and-wife comet and asteroid hunting team Eugene and Carolyn Shoemaker. The comets dramatic collision with Jupiter in July 1994, which constitute
36、d “the greatest planetary show in recorded history“ , to quote Malcolm W. Browne of the New York Times, captivated not only professional astronomers, but many amateurs. Although he is “only“ an amateur astronomer, he earns his living by lecturing and writing books and by working with project artists
37、. Theyre projects devoted to introducing astronomy to elementary school children. He has won tremendous respect from his professional colleagues for his success in tracking comets. “ David Levy is one of those rare individuals blessed with the gift of discovery,“ David Hartsel, who serves on the boa
38、rd of directors of the Richland Astronomical Society, in Ohio, has said. “Even rarer is his ability to let others share in the excitement and wonder of those discoveries through his writing and lectures.“ 52 The primary purpose of this passage is to_. （ A） praise Levy for his contribution to the obs
39、ervation of comets （ B） show that an amateur can do things as well as a professional （ C） introduce David Levy as an astronomer and his profession （ D） demonstrate that strong interest can help a person succeed in his life 53 All of the following are suggested in this passage as reasons for Levys su
40、ccess EXCEPT that_. （ A） he had books and articles published on astronomy （ B） he worked on projects intended to introduce astronomy （ C） he was endowed with the gift of the discovery of comets （ D） he was highly praised by his colleagues for his unselfishness 54 David Hartsel most appreciates Levys
41、_. （ A） gifted ability of comet hunting （ B） way of expressing himself （ C） curiosity to the sky and comets （ D） spirit of devotion to astronomy 54 Being a man has always been dangerous. There are about 105 males born for every 100 females, but this ratio drops to near balance at the age of maturity
42、, and among 70-year-olds there are twice as many women as men. But the great universal of male mortality is being changed. Now, boy babies survive almost as well as girls do. This means that, for the first time, there will be an excess of boys in those crucial years when they are searching for a mat
43、e. More important, another chance for natural selection has been removed. Fifty years ago, the chance of a baby(particularly a boy baby)surviving depended on its weight. A kilogram too light or too heavy meant almost certain death. Today it makes almost no difference. Since much of the variation is
44、due to genes, one more agent of evolution has gone. There is another way to commit evolutionary suicide: stay alive, but have fewer children. Few people are as fertile as in the past. Except in some religious communities, very few women have 15 children. Nowadays the number of births, like the age o
45、f death, has become average. Most of us have roughly the same number of offspring. Again, differences between people and the opportunity for natural selection to take advantage of it have diminished. India shows what is happening. The country offers wealth for a few in the great cities and poverty f
46、or the remaining tribal peoples. The grand mediocrity of today everyone being the same in survival and number of offspring means that natural selection has lost 80 percent of its power in upper-middle-class India compared to the tribes. For us, this means that evolution is over: the biological Utopi
47、a has arrived. Strangely, it has involved little physical change. No other species fills so many places in nature. But in the past 100,000 years even the past 100 years our lives have been transformed but our bodies have not. We did not evolve, because machines and society did it for us. Darwin had
48、a phrase to describe those ignorant of evolution: They “look at an organic being as a savage looks at a ship, as at something wholly beyond his comprehension“. No doubt we will remember a 20th century way of life beyond comprehension for its ugliness. But however amazed our descendants may be at how far from Utopia we were, they will look just like us. 55 What does the example of India illustrate? （ A） Wealthy people tend to have fewer children than poor people. （ B） Natural selection hardly works among the rich and the poor. （ C） The middle cla
