Each passage is followed by some questions or unfinished statements. For each

15、of them there are four choices marked A, B, C and D. You should decide on the best choice. 51 Many of the most damaging and life threatening types of weather-torrential rains, severe thunderstorms, and tornadoes-begin quickly, strike suddenly, and disappear rapidly, destroying small regions while le

16、aving neighboring areas untouched. Such event as a tornado struck the northeastern section of Edmonton, Alberta, in July 19 Total damages from the tornado exceeded $250 million, the highest ever for any Canadian storm. Conventional computer models Of the atmosphere have limited value in predicting s

17、hort lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the subtle atmospheric changes that come before these storms. In most nations, for example, weather-balloon observations are taken just once e

18、very twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events. Until recently, the observation intensive app

19、roach needed for accurate, very short-range forecasts, or “Nowcasts“, was not feasible. The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network

20、were hard to overcome Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications sa

21、tellites can transmit data around the world cheaply and instantaneously, and modem computers can quickly compile and analyze this large volume of weather information. Meteorologists (气象学者 ) and computer scientists now work together to design computer programs and video equipment capable of transform

22、ing raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality. 52 It can be inferred from the passage that the value of

23、 damages from torrential rains, severe thunderstorms and tornadoes is _. 53 Why do conventional models of the atmosphere fail to predict such a short-lived tornado? 54 It can be inferred from the passage that conventional forecasting models are now mostly used for _. 55 What does “Nowcasts“ mean acc

24、ording to the passage? 56 According to the passage, what makes “Nowcasting“ a reality? 56 What makes Americans spend nearly half their food dollars on meals away from home? The answers lie in the way Americans live today. During the first few decades of the twentieth century, canned and other conven

25、ience foods freed the family cook from full-time duty at the kitchen range. Then, in the 1940s, work in the wartime defense plants took more women out of the home than ever before, setting the pattern of the working wife and mother. Unless family members pitch in with food preparation, women are not

26、 fully liberated from that chore. Its easier to pick up a bucket of fried chicken on the way home from work or take the family out for pizzas or burgers than to start opening cans or heating up frozen dinners after a long, hard day. Also nowadays, the rising divorce rate means that there are more si

27、ngle working parents with children to feed. And many young adults and elderly people, as well as unmarried and divorced mature people, live alone rather than as a part of a family unit and dont want to bother cooking for one. Fast food is appealing because it is fast, it doesnt require tiny dressing

28、 up, it offers a “fun“ break in the daily routine, and the outlay of money seems small. It can be eaten in the car-sometimes picked up at a drive-in window without even getting out-or on the nm.

With advice from the FBI, each local chapter will be run by a board of directors that includes members of private industry, the academic community and publi

35、c agencies. Banks, utilities, and other businesses and government agencies will use a secure Web site to share information about attempts to hack into their computer networks. Members can join the system free. A key feature of the system is a two-pronged method of reporting attacks. A “sanitized“ de

36、scription of a hacking attempt or other incident-one that doesnt reveal the name or information about the victim-can be shared with the other members to spot trends. Then a mote detailed description also can be sent to the FBIs computer crimes unit to interfere if there are grounds for an investigat

37、ion.

38、. “Now any business with a modem is subject to attack.“ FBI agents investigate computer hacking that disrupted popular Web sites including Amazon. com, CNN and Yahoo! Several North Carolina victims have been identified this year. The investigation has also identified computer systems in North Caroli

39、na used by hackers to commit such attacks. Prosecutions of hackers have been hampered by the reluctance of companies to report security intrusions for fear of bad publicity and lost business. Meanwhile, too many corporations have made it too easy for criminals by sacrificing security for speed and a

40、ccessibility. Jack Wiles, who will lead the local InfraGard chapters board, said a recent report estimated 97 percent of all cyber crime goes undetected. Wiles, a computer security expert, has a firewall on his personal computer to prevent hackers from getting into his files. “I get at least one rep

M

48、y suggestion is to produce vehicles powered by solar energy. Compared with mineral fuels such as gasoline, solar energy is inexhaustible in supply. The growth of cities and increase of vehicles call for more supply of energy, but there is a limit to the reserve of off. So solar energy with its endless supply is one of our solutions to energy crisis. The second advantage of solar energy is its cleanliness. Traditional vehicles operating on gasoline give off exhaust, causing damage to huma
