| 第2题：The questions in this group are based on the content of a passage.After reading the passage, choose the best answer to each question.Answer all questions following the passage on the basis of what is stated or implied in the passage. Pretty much everybody agrees that clean air is a good thing, rightEvidently not so. Since the 1960s, when people started talking about clean air in the first place, theAmerican energy industry, which includes coal companies, oil companies, and utility companies, has dragged its heels on every initiative to improve the quality of the air we breathe.Even after theCleanAirAct of 1970 and its amendments in 1977 and 1990 made it clear that controlling air pollution is a national priority, these companies have found tricks and loopholes to avoid compliance. Perhaps the most egregious loophole is the one that allows older power plants to disregard limits on sulfux dioxide emissions until they undergo a major renovation, at which point they have to comply. Sulfur dioxide from coal-burning power plants is the primary cause of acid rain in NorthAmericA、TheCleanAirAct states that when coal-burning power plants upgrade their equipment, they must then comply with sulfur dioxide limitations by either installing scrubbing equipment that cleans the emissions or using fuel with lower sulfur content. The law tied the timing of compliance to major renovations in order to give power plants a grace period in which to comply. Many power plants, however, have exploited a loophole in this law by instituting a series of "minor" renovations that, in effect, upgrade their equipment without requiring them to comply with theCleanAirAct. Some plants have cheated the system by undergoing "minor" renovations for decades. The power companies claim that they have to resort to these underhanded measures because the cost of compliance with theCleanAirAct is too high.And if everyone else is cheating the system, why should they have to install costly sulfur dioxide scrubbers This cost argument falls apart upon scrutiny. Since 1977, more than 400 power plants across the country have managed to comply with the restrictions and are still making money. The sulfur dioxide scrubbing equipment has turned out to be far less expensive than the power industry naysayers claimed it would be. Many power plants have even complied with the emissions limits and reduced their operating costs by switching from high-sulfurAppalachian coal to the low-sulfur coal produced in western states such as Wyoming and Idaho. Western coal is not only cleaner than eastern coal, but also, because it is generally closer to the surface, as much as 30 percent less expensive to extract. Clearly, the costs of compliance with theCleanAirAct can be justified, but if these companies were honest, such justifications would not have to be made. If they were honest, they would acknowledge the costs of not complying: the health costs of increased rates of asthma and lung cancer in high-emissions areas; the environmental costs of acid-scarred forests and lakes; the aesthetic costs of a haze of sulfur dioxide cutting visibility across the eastern United States to only half of what it was in pre-industrial times. When you look at the true costs you have to ask, is any cost too high for clean air According to information given in the passage, which of the following statements presents the most accurate comparison of an average ton of coal from Wyoming with an average ton of coal from theAppalachian range in West Virginia A、The former is cheaper and has higher sulfur content than the latter. B、The latter is found closer to the surface and contains more sulfur than the former. C、The former can help coal-burning power plants meet limits on sulfur dioxide emissions and costs more than the latter. D、The latter generates more energy per pound of coa |

| 第3题：Companies that advertise on television complain that digital television recordingDTR) services make it possible for consumers to watch television programs without viewing the commercials that these advertisers have paid the television networks to broadcast. TheDTR service providers respond that their services may actually help the advertisers, because without their service, many consumers would not have been able to watch the programs--or the commercials in them--in the first place.

B、DTR services charge such high rates that only a small percentage of consumers subscribe to them. C、The average per-second cost of advertising on television has risen every year for the past two decades. D、More than 90 percent of subscribers toDTR services opt to use a setting that automatically edits out commercials. E、DTR services alter the television viewing experience by allowing customers to view the program of their choice at the time of their choosing. |
