The chances are equally good that you know a lot of smokers — there are, after all about 60 million of them, work with them, and get along with them very well. And finally it's a pretty safe bet that you're open-minded and interested in all the various issues about smokers and non-smokers — or you wouldn't be reading this. And those three things make you incredibly(难以置信地) important today. Because they mean that yours is the voice — not the smoker's and not the anti-smoker's — that will determine how much of society's efforts should go into building walls that separate us and how much into the search for solutions that bring us together. For one tragic result of the emphasis on building walls is the diversion(转移) of millions of dollars from scientific research on the causes and cures of diseases ,which, when all is said and done, still strike the nonsmoker as well as the smoker. One prominent(卓越的) health organization, to cite(引证) but a single instance, now spends 28 cents of every publicly contributed dollar on "education" (much of it in anti- smoking propaganda, and only 2 cents on research). There will always be some who want to build walls, who want to separate people from people, and up to a point, even these may serve society. The anti-smoking wall-builders have, to give them their due, helped to make us all more keenly aware of choice. But our guess, and certainly our hope, is that you are among the far greatest number who know that walls are only temporary(暂时的) at best, and that over the long run, we can serve society's interest better by working together in mutual accommodation. Whatever virtue walls may have, they can never move our society toward fundamental solutions. People who work together on common problems, common solutions, can.

单选题The World Cup This summer's World Cup competition will see teams competing to play the world's best football. But the football they play will not all be of the same kind. The fans expect different styles of play from Brazil, Germany, or Italy. What makes Brazilian football Brazilian? Our style of playing football contrasts with the Europeans because of a combination of qualities of surprise, accuracy and good judgment. This style has won Brazil five world cups. Yet many Brazilian fans only count four of these victories. In 1994, the team abandoned this style for modern, scientific training and tactics. The team won the cup, but in a boring way. The Italians think differently. "To many Italians, the score 0-0 has a glorious quality, suggesting perfection," says the British football writer Simon Kuper. In the Italian culture, the idea of face is very important. This is why Italian teams are traditionally built around strong defences. The Dutch footballer Johan Cruyff once said that Italian teams never exactly beat you. It's just that you often lose to them. In Holland, there is a tradition of decision making through argument and discussion. It is a society where everybody is expected to have a point of view. "Every Dutch player wants to control the game," says Arnold Muhren. "You play football with your brains and not your feet. " "A Dutch player argues," says Simon Kuper. "An English player obeys his superior. He is a soldier. " The qualities valued in English football are military-strength, aggression and courage. This can make for exciting football. But it also means that the English find it difficult to use skillful players. David Beckham is usually criticized for his failure to defend-despite the fact that he is an attacker. If the English like to fight, the Germans like to win. In recent years, Germany has tried to change its image as a country of ruthless efficiency and a desire for victory at all costs. But Germans are quite happy for these qualities to remain in their national football team. "Football is a simple game," Gary Lineker once said. "You kick a ball about for ninety minutes and in the end the Germans win. " It's difficult to predict who will win this year's World Cup. There is no strong favorite. But a look at the track record of previous winners shows that it is the nations with the strongest national characteristics in the football that perform best. It seems that you need to know where you come from if you want to get to the top.

That was Halloween。 In a few weeks American houses will be red and green and filled with presents, for Christmas. As if all this isn't enough, on Thursday this week, America will enjoy another festival - Thanksgiving. Children will have two days off school, shops will close and houses will be filled with families enjoying mountains of food. Every year, in Gainesville, Florida, an entire class celebrate Thanksgiving together. The class dresses up and puts on plays for their families. After the plays the families share a feast of traditional Thanksgiving foods like turkey and pumpkin pie. Dean Foster, an Il-year-old boy will take part in this celebration. He said: "I love Thanksgiving because it means time off school, lots of nice food and a happy family." His brother Ben, nine, said: "The best thing about Thanksgiving, is that when it is finished, it is time to start Christmas." But behind the food and the large amount of money spent there is another message. On Thursday evening, Dean and Ben's family will make a basket and put it on the table as they eat their evening meal. Each of them will write a list of things that they are thankful for and place the paper in the basket. The family will read the pieces of paper and take time to thank God and each other for providing them with comfortable and happy lives. Thanksgiving is a traditional festival that started in 1621, when the first pilgrims arrived in America to start a new life. After a hard year, they had a big autumn harvest. They held a feast and invited the native American Indians along to thank God for giving them enough food. Many countries celebrate Thanksgiving. They often fall after the fields have been harvested and the crops collected for winter.

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 1900s, 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 completely assemble a magneto, one of its elements was placed on a conveyor, 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 on piece at a time. It hasn"t been long before Ford was turning out several hundred and 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 and the world all 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.

单选题 阅读下成这篇短文，短文后列出了7个句子，请根据短文的内容对每个句子作出判断。 {{B}}Bees and Color{{/B}} On our table in the garden we put a blue card, and all around this blue card we put a number of different gray cards. These gray cards are of all possible shades of gray land include white and black. On each card a watch-glass is placed. The watch-glass on the blue card has some syrup (果汁) in it; all the others are empty. After a short time bees find the syrup, and they come for it again and again. Then, after some hours, we take away the watch-glass of syrup which was on the blue card and put an empty one in its place. Now what do the bees do? They still go straight to the blue card, although there is no syrup them. They do not go to any of the gray cards, in spite of the fact that one of the gray cards is of exacfiy the same brightness as the blue card. Thus the bees do not mistake any shade of gray for blue. In his way we have proved that they do really see blue as a color. We can find out in just the same way what other colors bees can see. It turns out that bees can see various colors, but these insects differ from us as regards their color-sense in two very interesting ways. Suppose we train bees to come to a red card, and, having done so, we put the red card on the table in the garden among the set of different gray cards. This time we find that the bees mistake red for dark gray or black. They cannot distinguish between them. This means that red is not a color at all for bees; for them it is just dark gray or black. That is one strange fact; here is another. A rainbow is red on one edge, violet on the other. Outside the violet of the rainbow there is another color which we cannot see at all. This color beyond the violet, invisible to us, is called the ultra-violet. Although it is invisible, we know that the ultra-violet is there because it affects a photographic plate. Now, although we are unable to see ultra-violet light, bees can do so; for them ultra-violet is a color. Thus bees see a color which we cannot even imagine. This has been found out by training bees to come for syrup to various parts of a spectrum, or artificial rainbow, thrown by a prism on a table in a dark room. In such an experiment the insects can be taught to fly to the ultra-violet, which for us is just darkness.

单选题 Telling Tales about People One of the most common types of nonfiction, and one that many people enjoy reading, is stories about people's lives. These stories fall into three general categories: autobiography, memoir, and biography. An autobiography is the story of a person's life written by himself or herself. Often it begins with the person's earliest recollections and ends in the present. Autobiography writers may not be entirely objective in the way they present themselves. However, they offer the reader a good look at the way they are and what makes them that way. People as diverse as Benjamin Franklin and Helen Keller have written autobiographies. Other writers, such as James Joyce, have written thinly fictionalized accounts of their lives. These are not autobiographies, but they are very close to it. Memoirs, strictly speaking, are autobiographical accounts that focus as much on the events of the times as on the life of the author. Memoir writers typically use these events as backdrops for their lives. They describe them in detail and discuss their importance. Recently, though, the term memoir seems to be becoming interchangeable with autobiography. A memoir nowadays may or may not deal with the outside world. Biographies are factual accounts of someone else's life. In many senses, these may be the hardest of the three types to write. Autobiography writers know the events they write about because they lived them. But biography writers have to gather information from as many different sources as possible. Then they have to decide which facts to include. Their goal is to present a balanced picture of a person, not one that is overly positive or too critical. A fair well-presented biography may take years to research and write.
