问题    Many Americans harbor 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 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). Declares Christina Stark, a nutritionist at Cornell University: "We’ve got far 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 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.
What does the author think of the Americans’ view of their food?
选项 A、They overlook the risks of the food they eat.
B、They overestimate the hazards of their food.
C、They are overoptimistic about the safety of their food.
D、They overstate the government’s interference with the food industry.
答案B
解析 因为文章第一段中的“grossly distorted and exaggerated view”对应答案项中的 overestimate；the risks对应答案项中的hazards。即，原文中的句子“许多美国人歪曲或夸张地估计了食品给人类带来的潜在危险”，与答案项的内容‘‘(美国人)他们过高地估计食品的危害”几乎等义。故选B项。
