问题     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 food, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives 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 essential 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 areas.
    Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: 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; they also produce eggs which lack important vitamins.
    There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. It is significant 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 presented in unrefined flour and of course in vegetables. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Hence emphasis placed on the eating of whole meal bread and more vegetables by modem experts on "healthy eating."
Which of the following can not be referred to as natural food?
选项 A、Vegetables and fruits with essential vitamins and minerals.
B、Foods grown in soil rich in organic matter.
C、Poultry fed in free pastures.
D、chickens raised on battery farms.
答案D
解析 本段落倒数第四行“Or perhaps—again not provable—by magnifying and extending irrational personal conflicts based on voice contact it impartially disseminates(传播)the useful knowledge of scientists and the nonsense of the ignorant，the affection of the affectionate and the malice(恶意)of the malicious”意为“电话一方面传播知识，而另一方面传播邪恶或无知的谎言”，因此，只有选项B正确，其他选项不符合题意。
