The new . plant, Vindicator of Florida Incorporated in Mulberry, Fla., uses a material called cobalt 60 to irradiate food. Cobalt 60 is radioactive isotope (form) of the metallic element cobalt. Cobalt 60, which gives off radiation in the form of gamma rays, is also used for radiation therapy for cancer patients and for sterilizing hospital equipment. The radioactive isotope is created by bombarding cobalt with subatomic particles in a nuclear reactor. However, irradiation plants do not themselves contain nuclear reactors. In the irradiation plant, food is exposed to thin rods of cobalt 60. The rods give off gamma rays, which disrupt chemical processes in contaminating anisms. The disruption breaks down the cell walls of anisms or destroys their geic material. The dose, set by the . Food and Drug Administration (FDA), is enough to kill anisms on food, but not enough to produce significant changes in the food itself. Although irradiation slightly decreases the nutritive value of foods, the loss is less than that produced by some other methods of food preservation. Canning, for example, results in a much greater loss of nutrients. Those who object to irradiation say that the process may create substances not found in nonirradiated food. Since the 1960’s researchers have studied irradiated food at microscopic levels to try to find such substances, called unique radiolytic products. After reviewing these studies, the FDA determined that pounds formed during irradiation are similar to substance found in nonirradiated foods and are not dangerous to consume. Destruction of microanisms that cause illness is an important goal of irradiation. About 250 million cases of food poisoning or 1 per person—occur every year in the U.S., according to FDA estimates. Food poisoning can cause vomiting, diarrhea, fever, headache—and, occasionally, death. Because of the apparent safety of food irradiation, and the problems presented by contaminated food, scientific groups—including the American Medical Association, the World Health Organization, and the United Nations food and Agriculture Association—have voiced nearly universal support for the process. Worldwide, 38 nations have approved irradiation for 355 products. 中國(guó)最大的資料庫下載 中國(guó)最大的資料庫下載 Like microwave ovens, food irradiation has aroused apprehension and misunderstanding. Yet it has been scrutinized more thoroughly than other methods of food treatment that we have e to regard as safe, and it appears to be a method whose time has come. 60, besides irradiating food, is also employed to ___. metallic flaws a nuclear reactor cancer patients concrete walls rays used to irradiate food ___. generally not strong enough to destroy contaminating anisms not bring about significant changes in the food itself destroy some of the nutrients in the food be submitted to FDA for approval food ___. loses its nutritive value its nutritive value no different from the nonirradiated its nutritive value better than canned food remended as the best of all preserved foods cases of food poisoning increasing, ___. irradiation should be carried out with care is more urgent to irradiate foods researches into treatment of the diseased should be strengthened are beginning to accept food irradiation passage may be taken from ___. news report textbook of food processing book of popular science manual of food irradiation 第 53篇答案： CBCCD 第 54篇： (Unit 14,Passage 2) Until recently, women in advertisements wore one of three things—an apron, a glamorous dress or a frown. Although that is now changing, many women still feel angry enough to deface offending advertisements with stickers protesting, “This ad degrades women.” Why does this sort of advertising exist? How can advertisers and ad agencie 中國(guó)最大的資料庫下載 中國(guó)最大的資料庫下載 s produce, sometimes, after months of research, advertising that offends the consumer? The Advertising Standards Authority (the body which deals with plaints about print media) is carrying out research into how women feel about the way they are portrayed in advertisements. Its conclusions are likely to be what the advertising industry already knows: although women often irritated by the way they are seen in ads, few feel strongly enough to plain. Women are not the only victims of poor and boring stereotypes—in many TV mercials men are seen either as useless, childish oafs who are unable to perform the simplest household tasks, or as in considerate boors, permanently on the lookout for an escape to the pub. But it is women who seem to bear the brunt of the industry’s apparent inability to put people into an authentic presentday context. Yet according to Emma Bent, executive creative director of a London advertising agency, women are not infuriated by stereotypes and sexist advertising. It tends to wash over them, they are not militant or angry—they just find it annoying or tiresome. They reluctantly accept outdated stereotypes, but heave a sigh of relief when an advertisement really gets it ri
