| 第2题：ManyAmericans harbor a grossly distorted and exaggerated view of most of the risks surrounding fooD、FergusClydesdale, head of the department of food science and nutrition at the University of Massachusetts-Amherst, says bluntly that if the dangers from bacterially contaminated chicken were as great as some people believe, "the streets would be littered with people lying here and there." Though the public increasingly demands no-risk food, there is no such thing.BruceAmes, chairman of the biochemistry department at the University ofCalifornia,Berkeley, points out that up to 10% of a plant’s weight is made up of natural pesticide (杀虫剂). Says he, "Since plants do not have jaws or teeth to protect themselves, they employ chemical warfare."And many naturally produced chemicals, though occurring in tiny amounts, prove in laboratory tests to be strong carcinogens—a substance that can cause cancer. Mushrooms (蘑菇) might be banned if they were judged by the same standards that apply to food additives (添加剂).DeclaresChristina Stark, a nutritionist atCornell University: "We’ve got far worse natural chemicals in the food supply than anything man-made. Yet the issues are not that simple. WhileAmericans have no reason to be terrified to sit down at the dinner table, they have every reason to demand significant improvements in food and water safety. They unconsciously and unwillingly take in too much of too many dangerous chemicals. If food already contains natural carcinogens, it does not make much sense to add dozens of new man-made ones. Though most people will withstand the small amounts of contaminants generally found in food and water, at least a few individuals will probably get cancer one day because of what they eat and drink. To make good food and water supplies even better, the Government needs to tighten its regulatory standards, stiffen its inspection program and strengthen its enforcement policies. The food industry should modify some long-accepted practices or turn to less hazardous alternatives. Perhaps most important, consumers will have to do a better job of learning how to select and cook food properly. The problems that need to be tackled exist all along the food-supply chain, from fields to processing plants to kitchens. The reduction of the possible hazards in food ultimately depends on______. A、the consumer B．the government C．the grower D．the processor |

Many retired people must cut their spending to (60) rising prices.

| 第4题：Predicting the future is risky business for a scientist. It is safe to say, however, that the globalAIDS epidemic will get much worse before it gets any better. Sadly, this modern plague will be with us for several generations, despite major scientific advances. As of January 2000, theAIDS epidemic had claimed 15 million lives and left 40 million people living with a viral infection that slowly but relentlessly erodes the immune system.Accounting for more than 3 million deaths in the past year alone, theAIDS virus has become the deadliest microbe in the worlD、InAfrica nearly a dozen countries have a rate higher than 10%, including four southernAfrican nations in which a quarter of the people are infecteD、This is like condemning 16 000 people each day to a slow and miserable death. Fortunately, theAIDS story has not been all gloom and doom. Less than two years afterAIDS was recognized, the guilty agent—human immunodeficiency virus, or HIV—was identifieD、We now know more about HIV than about any other virus, and 14AIDS drugs have been developed and licensed in the U.S. and WesternEurope. The epidemic continues to rage, however, in SouthAmerica,EasternEurope and sub-SaharanAfric A、By the year 2025,AIDS will be by far the major killer of youngAfricans, decreasing life expectancy to as low as 40 years in some countries and single-handedly erasing the public health gains of the past 50 years. It isAsia, with its huge population at risk, that will have the biggest impact on the global spread ofAIDS. The magnitude of the incidence could range from 100 million to 1 billion, depending largely on what happens in India andChin A、Four million people have already become HIV-positive in India, and infection is likely to reach several percent in a population of 1 billion. Half a millionChinese are now infected; the path ofChina’s epidemic, however, is less certain. An explosiveAIDS epidemic in the U.S. is unlikely. Instead, HIV infection will continue to plague in about 0.5% of the population.But the complexion of the epidemic will change. New HIV infections will occur predominantly in the underclass, with rates 10 times as high in minority groups. Nevertheless,American patients will live quality lives for decades, thanks to advances in medical research.Dozens of powerful and well-toleratedAIDS drugs will be developed, as will novel means to restore the immune system. A、cure forAIDS by the year 2025 is not inconceivable.But constrained by economic reality, these therapeutic advances will have only limited benefit outside the U.S. and WesternEurope. Which of the following could be the best title for this passage A、The Spread of HIV — Will WeEverCureAIDS B、The Worse Situation ofAIDS — WillAIDS Ruin the Human Race C、The Statistics ofAIDS — WillAIDS Spread around the World D、The Potential of HIV — WillAsiaBecome theCore ofAIDS |
