单选题The Forbidden Apple New York used to be the city that never sleeps. These days it's the city that never smokes, drinks or does anything naughty(at least, not in public). The Big Apple is quickly turning into the Forbidden Apple. If you wanted a glass of wine with your picnic in Central Park, could you have one? No chance. Drinking alcohol in public isn't allowed. If you decided to feed the birds with the last crumbs(碎屑)of your sandwich, you could be arrested. It's illegal. If you went to a bar for a drink and a cigarette, that would be OK, wouldn't it? Er...no. You can't smoke in public in New York City. What's going on? Why is the city that used to be so open-minded becoming like this? The mayor of New York is behind it all. He has brought in a whole lot of new laws to stop citizens from doing what they want, when they want. The press are shocked. Even the New York police have joined the argument. They recently spent $ 100,000 on a "Don't blame the cop' campaign. One New York police officer said, "We raise money for the city by giving people fines for breaking some very stupid laws. It's all about money. " The result is a lot of fines for minor offences. Yoav Kashida, an Israeli tourist, fell asleep on the subway. When he woke up, wo police officers fined him because he had fallen asleep on two seats(you mustn't use two seats in the subway). Elle and Serge Schroitman were fined for blocking a driveway with their car. It was their own driveway. The angry editor of Vanity Fair magazine, Graydon Carter. says, "Under New York City law it is acceptable to keep a gun in your place of work, but not an empty ashtray. "He should know. The police came to his office and took away his ashtray(烟灰缸). But not all of New York's inhabitants are complaining. Marcia Dugarry, 72, said, "The city has changed for the better. If more cities had these laws, America would be a better place to live. "Nixon Patotkis, 38, a barman, said , "I like the new laws. If people smoked in here, we'd go home smelling of cigarettes. " Recent figures show that New York now has fewer crimes per 100,000 people than 193 other US cities. And it's true—it's safer, cleaner and more healthy than before. But let's be honest—who goes to New York for its clean streets?

单选题Air Pollution Cloud Measured on Both Sides of Pacific Scientists watched closely last spring as a haze of pollution, which had been tracked by satellite as it crossed the Pacific Ocean, settled over a large swath of North America from Calgary, Canada, into Arizona. Now it appears that, for the first time, researchers on both sides of the Pacific took detailed measurements of the same plume, a could that contained Gobi dessert dust as well as hydrocarbons (碳氢化合物) from industrial pollution. Heather Price, a University of Washington doctoral student in chemistry, found that the amount of light reflected by the particles in the air was more than 550 percent greater than normal for that time of year. The mass of Asian air contained elevated levels of all pollutants measured. Price said, "but the only thing that came close to being alarming was the level of particulate matter. " The haze that settled across the western part the the country was widely reported by the news media, and it was measured as far inland as the ski slopes of Aspen, Colo. Readings on the western side of the Pacific came from the Aerosol Characterization Experiments, a project aimed at understanding how particles in the atmosphere affect Earth's climate. Additional measurements were taken in the same region at the same time under a project sponsored by the National Aeronautics and Space Administration. Knowing the pollution was approaching Washington state, Price loaded sensing equipment aboard a rented Beechcraft on April 14 and flew to Neah Bay on the state's Northwest coast. Taking samples at various levels from 15,000 feet to 20,000 feet in altitude, she monitored 10 quantities of dust, ozone, carbon monoxide and hydrocarbons. "From my copilot's seat, the dust was thick enough to see with the naked eye," Price said. Now she 's trying to correlate her findings with those of the two research teams operating on the other side of the Pacific, where at one point the pollution plume was larger than Japan. The huge size of the cloud showed up clearly in satellite images that gave Price plenty of warning the haze was on its way. "You can see these two blobs coming out of the deserts of Mongolia and growing over Asia, then getting swept out over the ocean and finally setting over North America," she said. She intends to continue measuring air samples off the Washington coast and will be looking for air masses with evidence of pollution originating somewhere other than Asia. "We'd like to see if we can get a signature of pollution coming from Europe because computer models suggest that European sources also can be transported across the pacific," she Said. "However, we expect that sources in Europe will contribute less than Asian sources. /

单选题{{B}}第三篇{{/B}} Ford Abandons Electric Vehicles The Ford motor company's abandonment of electric cars effectively signals the end of the road for the technology, analysts say. General Motor and Honda' ceased production of battery, powered cars in 1999, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumer. Ford has now announced it will do the same. Three years ago, the company introduced the Think City two-seater car and a golf cart called the THINK, or ThinkNeighbor. It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and less than 1,700 carts have been sold so far in 2002. "The bottom line is we don't believe that this is the future of environment transport for the mass market. "Tim Holmes of Ford Europe said on Friday. "We feel we have given electric our best shot". The Think City has a range of only about 53 miles and up to a six-hour battery recharge time. General Motors' EVI electric vehicle also had a limited range, of about 100 miles. The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyot-RAV4 EV vehicle costs over $ 42,000 in the US, compared with just $17,000 for the petrol version. Toyota and Nissan are now the only major auto manufacturers to produce electric vehicles. "There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program, and that is what we will be judging them on. " Roger Higman, a senior transport campaigner at UK Friends of the Earth, told the Environment News Service. Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrol-only engines , and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines "on vehicle emissions" in the U.S. However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring car-makers to offer 100,000 zero-emission and other low-emission vehicles in the state by 2003. Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.

单选题{{B}}第三篇{{/B}} {{B}}Importance of Services{{/B}} The United States has moved beyond the industrial economy stage to the point where it has become the world's first service economy. Almost three-fourths of the nonfarm labor force is employed in service industries, and over two-thirds of the nation's gross national product is accounted for by services. Also, service jobs typically hold up better during a recession than do jobs in industries producing tangible goods. During the 20-year period of 1966 to 1986, about 36 million new jobs were created in the United States--far more than in Japan and Western Europe combined. About 90 percent of these jobs were in service industries. During this same time span, some 22 million women joined the labor force--and 97 percent of these women went to work in the service sector. These employment trends are expected to continue at least until the year 2000. For the period 1986- 2000, the Bureau of Labor Statistics predicts that over 21 million new jobs will be created and 93 percent of them will be in service industries. Moreover, most of this explosive growth in services employment is not in low-paying jobs, contrary to the beliefs of many economists, business and labor leaders, and politicians. These people argue that manufacturing jobs, which have been the economic foundation of America's middle class, are vanishing. They claim that factory workers are being replaced with a host of low-wage earners. It is tree that manufacturing jobs have declined, with many of them going to foreign countries. It is also true that there has been growth in some low-paying service jobs. Yet cooks and counter people still represent only 1 percent of the U.S. labor force today. Furthermore, for many years the fastest-growing occupational category has been "professional, technical, and related work." These jobs pay well above the average, and most are in service industries. About one-half of consumer expenditures are for the purchase of services. Projections to the year 2000 indicate that services will attract an even larger share of consumer spending. A drawback of the service economy boom is that the prices of most services have been going up at a considerably faster rate than the prices of most tangible products. You are undoubtedly aware of this if you have had your car or TV set repaired, had your shoes half-soled, or paid a medical bill in recent years. When we say that services account for close to one-half of consumer expenditures, we still grossly understate the economic importance of services. These figures do not include the vast amounts spent for business services. By all indications, spending for business services has increased even more rapidly than spending for consumer services.

单选题 Knitting My mother knew how to knit (纺织), but she never taught me. She assumed, as did many women of her generation, that knitting was no longer a skill worth passing down from mother to daughter. A combination of feminism (女权主义) and consumerism (消费主义) made many women feel that such homely accomplishments were now out of date. My grandmother still knitted, though, and every Christmas she made a pair of socks for my brother and me, of red wool (毛线). They were the ones we wore under our ice skates (冰鞋), when it was really important to have warm feet. Knitting is a nervous habit that happens to be productive. It helped me {{B}}quit{{/B}} smoking by giving my hands something else to do. It is wonderful for depression because no matter what else happens, you are creating something beautiful. Time spent in front of the television or just sitting is no longer time wasted. I love breathing life into the patterns. It's true magic, finding a neglected, dog-eared (翻旧了的) old book with the perfect snowflake design, buying the same Germantown wool my grandmother used, in the exact blue to match my daughter's eyes, taking it on the train with me every day for two months, working enthusiastically to get it done by Christmas, staying up late after the stockings are filled to sew in the sleeves and weave in the ends. Knitting has taught me patience. I know that if I just keep going, even if it takes months, there will be a reward. When I make a mistake, I know that anger will not fix it, and that I just have to go back and start over again. People often ask if I would do it for money, and the answer is always a definite no. In the first place, you could not pay me enough for the hours I put into a sweater. But more important, this is an activity I keep separate from such considerations. I knit to cover my children and other people I love in warmth and color. I knit to give them something earthly that money could never buy. Knitting gives my life an alternative rhythm to the daily deadline. By day I can write about Northern Ireland or the New York City Police Department and get paid for it, but on the train home, surrounded by people with laptops, I stage my little rebellion. I take out my old knitting bag and join the centuries of women who have knitted for love.

单选题Can Buildings Be Designed to Resist Terrorist Attack In the aftermath of the terrorist attack on the World Trade Center, structural engineers are trying hard to solve a question that a month ago would have been completely unthinkable. Can building be designed to withstand catastrophic blasts inflicted by terrorists? Ten days after the terrorist attacks on the twin towers, structural engineers from the University at Buffalo and the Multidisciplinary Center for Earthquake Engineering Research (MCEER) headquartered at UB traveled to ground zero as part of a project funded by the National Science Foundation. Visiting the site as part of an MCEER reconnaissance visit, they spent two days beginning the task of formulating ideas about how to design such structures and searching for clues on how to do so in buildings that were damaged, but still are standing. "Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade Center, those buildings that are still standing, but that sustained damage, "said M. Bruneau, Ph. D. "Our immediate hope is that we can develop a better understanding as to why those buildings remain standing, while our long-term goal is to see whether earthquake engineering technologies can be married to existing technologies to achieve enhanced performance of buildings in the event of terrorist attacks." he added. Photographs taken by the investigators demonstrate in startling detail the monumental damage inflicted on the World Trade Center towers and buildings in the vicinity. One building a block away from the towers remains standing, but was badly damaged. "This building is many meters away from the World Trade Center and yet we see a column there that used to be part of that building", explained A. Whittaker, Ph. D. "The column became a missile that shot across the road, through the window and through the floor." The visit to the area also revealed some surprises, according to the engineers. For example, the floor framing systems in one of the adjacent buildings was quite rugged, allowing floors that were pierced by tons of falling debris to remain intact. "Highly redundant ductile framing systems may provide a simple, but robust strategy for blast resistance." he added. Other strategies may include providing alternate paths for gravity loads in the event that a load-bearing column fails. "We also need a better understanding of the mechanism of collapse", said A. Whittaker. "We need to find out what causes a building to collapse and how you can predict it." A. Reinhorn, Ph. D. noted that "earthquake shaking has led to the collapse of many buildings in the past. It induces dynamic response and extremely high stresses and deformations in structural components. Solutions developed for earthquake-resistant design may be directly applicable to blast engineering and terrorist-resistant design. Part of our mission now at UB is to transfer these solutions and to develop new ones where none exist at present."

单选题A Country"s Standard of Living The "standard of living" of any country means the average person"s share of the goods and services the country produces. A country"s standard of living, therefore 1 first on its capacity to produce wealth. "Wealth" in this 2 is not money, for we do not live on money but on things that money can buy: "goods" such as food and clothing, and "services" such as transport and entertainment. A country"s capacity to 3 wealth depends upon many factors, most of 4 have an effect on one another. Wealth depends 5 a great extent upon a country"s natural resources. Some regions of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate; other regions 6 none of them. Next to natural resources comes the ability to 7 them to use. China is perhaps as rich as the USA in natural resources, but suffered for many years 8 civil and external wars, and for this and other 9 was unable to develop her resources. Sound and stable political conditions, and 10 from foreign invasions, enable a country to develop its natural resources peacefully and steadily, and to produce more 11 than another country equally well favored by nature but less well ordered. A country"s standard of living does not only depend upon the wealth that is produced and 12 within its own borders, but also upon what is directly produced through international trade for mple, Britain"s wealth in foodstuffs and other agricultural 13 would be much less if she had to depend only on those grown at home. Trade makes it possible for the surplus (过剩的) manufactured goods to be traded abroad for the agricultural products 14 would otherwise be lacking. A country"s wealth is, therefore, much influenced by its manufacturing capacity. 15 that other countries can be found ready to accept its manufactures.

单选题Supermarket Most supermarkets need a very large floor area, sometimes at least ten times as big as that of an ordinary shop. There are usually two doors, one as an entrance and the other as an exit. The rest of the side facing the street is largely of plate grass, with goods or advertising materials displayed. The other three walls are normally decorated in light colors, giving an impression of cleanliness (清洁) and brightness. Most supermarkets are on one floor only, goods being stored in rooms at the hack or upstairs. At right-angles to the window stretch long structures about six feet high with a number of shelves on each side. Similar shelf units or frozen food containers extend round the walls. Broad aisles (通道) between the shelf units and ample (足够的) space between them and the window and also the far wall allow room for the circulation of many people. Individual commodities (商品), in tins, bags, boxes or other containers, are stacked (堆放) in groups on the shelves, and each group is labeled with a price ticket. Metal baskets near the entrance are taken by the shoppers who collect in them the goods they select from the shelves. Between the shelf units and the window in one half of the shops are a number of small counters about three feet high. Beside each sits a cashier (现金出纳员), who operates a machine for totaling the cost of each customers' purchases. The customer places the basket at one end of the counter so that ii can be emptied by the cashier who records the price of the commodities one by one, before putting each on a moving section of the counter top. The goods are collected and packed into the customer's hag by another assistant at the end of the counter. The cashier finally hands a printed slip recording all prices to the customer, who pays the total, collects the bag and leaves.
