问题                                Irradiating Food
   Irradiating fruits, vegetables, pork and chicken to kill insects and bacteria has been approved by the Food and Drug Administration over the past decade or so. Irradiation of other meats, such as beef and lamb, is being reviewed. Federal approval does not require that industry adopt the process, and few food processors presently offer irradiated products.
   Market studies have shown that many consumers are afraid that eating irradiated foods may cause cancer, despite scientific studies that prove the safety of treated foods. Some people argue that more severe government inspection, higher food-safety standards, and more careful-preparation practices by consumers are all that is needed to ensure that food is safe. Consequently, companies currently see no need to spend millions of dollars outfitting processing plants with the equipment necessary for a process that very few shoppers are in favor of.
   All supermarkets that sell irradiated food must label the food either directly on the packaging, or, in the case of bulk items like fruits and vegetables, by placing a sign nearby. There is no requirement for the labeling of irradiated food served by chain restaurants or hospitals that buy directly from distributors, nor any regulations for products that contain irradiated ingredients.
   Presently, the FDA allows food to be treated with three types of radiation—gamma rays, high-energy electrons, and X rays—and sets limits on doses, depending on the type of food. The principle is that the dose to be used for a certain type of food should not exceed the amount that is sufficient to kill most harmful insects and bacteria present in it. Different types of food, because of their molecular compositions, may require different doses of radiation.

选项 A、Right
B、Wrong
C、Not mentioned

答案A

解析 在看题干时尤其需要注意题干中出现的修饰词——形容词/副词。利用专有名词“US government”和核心结构“killing insects and bacteria”作为答案线索词,在第1段找到答案相关句:Irradiating fruits, vegetable, pork and chicken to kill insects and bacteria has been approved by the Food and Durg Administration  (Food and Drug Administration是美国政府下设的食品和药品管理局)(与题干中的“US government”呼应)over the past decade or so.Irradiation of other meats,such as beef and lamb,is being reviewed.划线句说“对水果、蔬菜、猪肉和肌肉进行放射处理以杀死其中的昆虫和细菌已经获得美国食品和药品管理局的批准”,但是“对其他肉类进行放射处理的做法还在进行审查”,根据这两句话的内容判断问题句“通过对食物进行放射以杀死食物中的昆虫和细菌的做法还没有得到美国政府的完全批准”正确。
