Question

阅读理解 　　Increasingly, over the past ten years, people－especially young people－have become aware of the need to change their eating habits, because much of the food they eat, particularly processed(加工过的)foods, is not good for health, so there has been a growing interest in natural foods：foods which do not contain chemical additives(添加剂)and which have not been affected by chemical fertilizers widely used in farming today． 　　Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matter．In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with basic vitamins and minerals．This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount but not the quality of foods grown in commercial farming(经济农场)areas． 　　Natural foods also include animals which have been allowed to feed and move freely in healthy grassland．Compare this with what happens in the mass production of poultry(家禽)：there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish．Chickens kept in this way are not only tasteless as food; but also produce eggs which lack important vitamins． 　　There are other aspects of healthy eating which are now receiving increasing attention from experts on diet．Take, for example, the question of sugar．This is actually an　unimportant food!Although a natural choice, such as honey, can be used to sweeten food if this necessary, we can in fact do without it．It is not that sugar is harmful in itself．Yet all it does is provide us with energy, in the form of calories．There are no vitamins in it, no minerals and no fiber．It is important that nowadays fiber is considered to be an important part of a healthy diet．In white bread, for example, the fiber has been removed．But it is present in unrefined(未精炼的)flour and of course in vegetables．Thus the emphasis is placed on the eating of whole meal bread and more vegetables by modern experts on “healthy eating”． (1) Which statement best expresses the main idea of this article? [　　] A． People should eat any food to keep themselves healthy and strong． B． People should eat natural foods to keep themselves healthy and strong． C． People should eat fiber foods to keep themselves healthy and strong． D． People should eat vegetables to keep themselves healthy and strong． (2) “Particularly processed foods” means _________． [　　] A． foods which are particularly processed by adding chemical additives B． foods which are particularly made by commercial farms(经济农场) C． foods which are specially produced by commercial factories D． foods which are not specially made by adding anything (3) Natural foods means _________． [　　] A． foods good for health B． foods not good for health C． foods such as vegetables, fruit and grain from rich organic matters soil D． crops from rich organic matters soil and meats of animals from healthy grassland (4) There are no vitamins, no minerals and no fibers in _________． [　　] A． natural foods B． sugar C． animal meats D． fruit (5) “Yet all it does is provide us with energy, in the form of calories．” Here “it” means _________． [　　] A． processed food that provides us with energy B． natural food that furnishes us with vitamins and minerals C． sugar that gives us enough energy in the form of calories D． fiber that helps us to digest food

Answer 1

答案：1．B;2．A;3．D;4．B;5．C;
解析：

(1)	主旨大意题。人们越来越多地意识到需要改变饮食习惯，而对天然的食物表现出更多的兴趣，因为天然食物不含化学添加剂，没有被化肥污染。根据文章内容，健康食品应该是一切天然食品，而不仅仅是蔬菜、纤维食品和其他的食品。
(2)	此题考查细节理解。加工食品实际上是加了化学添加剂的食品, 它既不是商业农场、商业工厂生产的食品, 也不是其他未作特殊处理的食品。见文章第一段。
(3)	此题考查对文章主题的范围及定义的理解。天然食品是指从有丰富有机物的土壤里生长出的农作物和生活在有益于健康的牧场上自由觅食，自由奔跑的动物的肉类。文章第二段第一句及第三段第一句提供了此答案。
(4)	此题考查细节。糖既不含维生素、矿物质, 也无任何纤维。参见文章第四段最后两句话。
(5)	本题为结合上下文理解细节题。由上下文可知，句中的“it”指代的是“糖”，而非其他。
