问题    Many Americans harbour a grossly distorted and exaggerated view of most of the risks surrounding food. Fergus Clydesdale, 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. Bruce Ames, chairman of the biochemistry department at the University of California, Berkeley, points out that up to 10% of a plant’s weight is made up of natural pesticides. 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 which can cause cancer. Mushrooms might be banned if they were judged by the same standards that apply to food additives. Declares Christina Stark, a nutritionist at Cornell University-. "We’ve got fat worse natural chemicals in the food supply than anything man-made. "
   Yet the issues are not that simple. While Americans 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 manmade 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 handle 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.
What is the message the author wants to convey in the passage?

选项 A、Eating and drinking have become more hazardous than before.
B、Immediate measures must be taken to improve food production and processing.
C、Health food is not a dream in modern society.
D、There is reason for caution but no cause for alarm with regard to food consumption.

答案D

解析 主旨大意题。第一段指出美国人对食品风险的高估,第二段说明绝对安全的食品是不存在的,第三段讲到尽管没有绝对安全的食品,但人们仍然可以对食品安全提出更高的要求,最后一段是对改进食品安全提出建议。可见,作者认为,对待食品安全,不用过分担忧,但又要小心谨慎,[D]项是原文信息的概括,故为答案。在食品和饮水安全方面,作者并未将过去和现在进行比较,故排除[A]项;虽然认为食品的生产和处理要加强安全保障,但是并没有说事出紧急,故排除[B]项;文章的主题是食品安全,[C]项偷换概念为health food,故排除。
