Food is irradiated (用辐射处理) to provide the same benefits as when
it is processed by heat, refrigeration, freezing or treated with chemicals to
destroy insects, fungi or bacterium that cause food to spoil or cause human 【M1】______
disease and to make possible to keep food longer and in better condition in 【M2】______
warehouses and homes. Irradiated foods are wholesome and nutritional. All 【M3】______
known methods of food processing and even storing food at room tempera
ture for a few hours after harvesting can lower the content of some nutrients,
such as vitamins. At low doses of radiation, nutrient losses are either not
measurable or, if they can be measured, are not significant.
At the higher doses used to extend shelf life or control harmful bacteria,
nutritional losses are less than or about the same with cooking and freezing. 【M4】______
The irradiation process involves passing food through an irra
diation field; however, the food itself never contacts with a radioactive 【M5】______
matter. Also the ionizing radiation used by irradiators is not strong enough 【M6】______
to disintegrate the nucleus of even one atom of a food molecule.
Irradiation does produce chemical changes in foods. They have been
scrutinized by scientists in making safe assessments of irradiated foods. 【M7】______
Any kind of treatments causes chemical changes in food. For instance, heat 【M8】______
treatment, or cooking, produces chemicals that could be called ""thermolytic
products."" Scientists find the changes in food created by irradiation minor to
that created by cooking. The products created by cooking are so significant 【M9】______
that consumers can smell and taste them, whereas only a chemist with ex
tremely sensible lab equipment may be able to detect radio lytic products. 【M10】______ [br] 【M6】
选项
答案
matter — substance
解析
此题辨析substance和matter。substance的意思是“物质”,指一种有物理或化学性质的固体、液体或气体,是可数名词,是个体名词;matter的意思是“事情、物质”,matter作为“物质”这个意思时,是一个不可数名词。原句的名词前有不定冠词修饰,应该用可数名词substance。
