单选题The Iceman On a September day in 199], two Germans were climbing the mountains between Austria and Italy. High up on a mountain pass, they found the body of a man lying on the ice. At that height (10,499 feet, or 3,200 meters), the ice is usually permanent, but 1991 had been an especially warm year. The mountain ice had melted more than usual and so the body had come to the surface. It was lying face downward. The skeleton (骨架) was in perfect condition, except for a wound in the head. There was still skin on the bones and the remains of some clothes. The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots. Nearby was a pair of gloves made of tree bark (树皮) and a holder for arrows. Who was this man? How and when had he died? Everybody had a different answer to these questions. Some people thought that it was from this century, perhaps the body of a soldier who died in World War I, since several soldiers had already been found in the area. A Swiss woman believed it might be her father, who had died in those mountains twenty years before and whose body had never been found. The scientists who rushed to look at the body thought it was probably much older, maybe even a thousand years old. With modern dating techniques, the scientists soon learned that the Iceman was about 5,300 years old. Born in about 3300 B.C., he lived during the Bronze Age in Europe. At first, scientist thought he was probably a hunter who had died from an accident in the high mountains. More recent evidence, however, tells a different story. A new kind of X-ray shows an arrowhead still stuck in his shoulder. It left only a tiny hole in his skin, but it caused internal damage and bleeding. He almost certainly died from this wound, and not from the wound on the back of his head. This means that he was probably in some kind of a battle. It may have been part of a larger war or he may have been fighting bandits. He may even have been a bandit himself. By studying his clothes and tools, scientists have already learned a great deal from the Iceman about the times he lived in. We may never know the full story of how he died, but he has give us important clues to the history of those distant times.

单选题 The Adjustment in Understanding of Man's Relation to the Physical Universe Nowadays the scattering of galaxies and the astounding abundance of stars are forcing those who ponder such matters to a further adjustment of their concept of the place and function of man in the material universe. In the history of the {{U}} {{U}} 1 {{/U}} {{/U}}human mind, with its increasing knowledge of the surrounding context, there must have been a time when the philosophers of the {{U}} {{U}} 2 {{/U}} {{/U}}tribes began to realize that the world was not simply centered on man himself.

This {{U}} {{U}} 7 {{/U}} {{/U}}has deeply exploded man's pride and {{U}} {{U}} 8 {{/U}} {{/U}}, for it has carried with it the knowledge of the appalling number of galaxies. The galactocentric universe {{U}} {{U}} 9 {{/U}} {{/U}}puts the earth and its life near the edge of one great galaxy in a universe of millions of galaxies.

单选题Lateral Thinking Lateral thinking (迂回思维), first described by Edward de Bono in 1967, is just a few years older than Edward's son. You might imagine that Casper was raised to be an adventurous thinker, but de Bono name was so famous, Casper's parents worried that any time he would say something bright at school, his teachers might snap, "Where do you get that idea from?" "We had to be careful and not overdo it," Edward admits. Now Casper is at Oxford — which once looked unlikely because he is also slightly dyslexic (诵读困难). In fact, when he was applying to Oxford, none of his school teachers thought he had a chance. "So then we did several thinking sessions," his father says, "using my techniques and, when he went up for the exam, he did extremely well." Soon after, Edward de Bono decided to write his latest book, Teach Your Children How to Think, in which he transforms the thinking skills he developed for brain-storming businessmen into informal exercises for parents and children to share. Thinking is traditionally regarded as something executed in a logical sequence, and everybody knows that children aren't very logical. So isn't it an uphill battle, trying to teach them to think? "You know," Edward de Bono says, "if you examine people's thinking, it is quite unusual to find faults of logic. But the faults of perception are huge! Often we think ineffectively because we take too limited a view." Teach Your Child How to Think offers lessons in perception improvement, of clearly seeing the implications of something you are saying and of exploring the alternatives.

单选题A Letter from Alan I have learnt of a plan to build three hundred houses on the land called Parson's Place by the football ground. Few people know about this new plan to increase the size of our town. For me, Parson's Place is special because it is a beautiful natural area where local people can relax—the small wood has many unusual trees and the stream is popular with fishermen and bird-watchers. It's very quiet because there are few houses or roads nearby. I think that losing this area will be terrible because we have no other similar facilities in the neighbourhood. I am also against this plan because it will cause traffic problems. How will the people from the new houses travel to work? The motorway and the railway station are on the other side of town. Therefore, these people will have to drive through the town centre every time they go anywhere. The roads will always be full of traffic, there will be nowhere to park and the tourists who come to see our lovely old buildings will leave. Shops and hotels will lose business. If the town really needs more homes, the empty ground beside the railway station is a more suitable place. No doubt the builders will make a lot of money by selling these houses. But, in my opinion, the average person will quickly be made poorer by this plan. As well as this, we will lose a very special place and our town will be much less pleasant. I am going to the local government offices on Monday morning to protest about this plan and I hope that your readers will join me there. We must make them stop this plan before it is too late.

单选题{{B}}第二篇{{/B}} {{B}}Eiffel Is an Eyeful{{/B}} Some 300 meters up, near the Eiffel Tower's wind-whipped summit the world comes to scribble. Japanese, Brazilians, Americans — they graffiti their names, loves and politics on the cold iron — transforming the most French of monuments into symbol of a world on the move. With Paris laid out in miniature below, it seems strange that visitors would rather waste time marking their presence than admiring the view. But the graffiti also raises a question: Why, nearly 114 years after it was completed, and decades after it ceased to be the world's tallest structure, is la Tour Eiffel still so popular? The reasons are as complex as the iron work that graces a structure some 90 stories high. But part of the answer is, no doubt, its agelessness. Regularly maintained, it should never rust away. Graffiti is regularly painted over, but the tower lives on. "Eiffel represents Paris and Paris is France. It is very symbolic," says Hugues Richard, a 31-year-old Frenchman who holds the record for cycling up to the tower's second floor — 747 steps in 19 minutes and 4 seconds, without touching the floor with his feet. "It's iron lady, it inspires us," he says. But to what? After all, the tower doesn't have a purpose. It ceased to be the world's tallest in 1930 when the Chrysler Building went up in New York. Yes, television and radio signals are beamed from the top, and Gustave Eiffel, a frenetic builder who died on December 27, aged 91, used its height for conducting research into weather, aerodynamics and radio communication. But in essence the tower inspires simply by being there — a bland canvas for visitors make of it what they will. To the technically minded, it's an engineering triumph. For lovers, it's romantic. "The tower will outlast all of us, and by a long way," says Isabelle Esnous, whose company manages Eiffel Tower.

单选题Ford's Assembly Line When it comes to singling out those who have made a difference in all our lives, you cannot overlook Henry Ford. A historian a century from now might well conclude that it was Ford who most influenced all manufacturing, everywhere, even to this day, by introducing a new way to make cars-one, strange to say, that originated in slaughterhouses (屠宰场). Back in the early 1900's, slaughterhouses used what could have been called a "disassembly line". Ford reversed this process to see if it would speed up production of a part of an automobile engine called a magneto. Rather than have each worker complelely assemble a magneto, one of its elements was placed on a conveyer, and each worker, as it passed, added another component to it, the same one each time. Professor David Hounshell of the University of Delaware, an expert on industrial development, tells what happened: "The previous day, workers carrying out the entire process had averaged one assembly every 20 minutes. But on that day, on the line, the assembly team averaged one every 13 minutes and 10 seconds per person. " Within a year, the time had been reduced to five minutes. In 1913, Ford went all the way. Hooked together by ropes, partially assembled vehicles were towed (拖，拉) past workers who completed them one piece at a time. It wasn't long before Ford was turning out several hundred thousand cars a year, a remarkable achievement then. And so efficient and economical was this new system that he cut the price of his cars in half, to $260, putting them within reach of all those who, up until that time, could not afford them. Soon, auto makers the world over copied him. In fact, he encouraged them to do so by writing a book about all of his innovations, entitled Today and Tomorrow. The Age of the Automobile has arrived. Today, aided by robots and other forms of automation (自动化), everything from toasters to perfumes is made on assembly lines.
