　　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 health. Consequently, there has been a growing interest in natural foods , foods which do not contain chemical additives(添加劑) and which have not been affected by chemical fertilizer (化肥) 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(養(yǎng)育) 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 area.

　　Natural foods also include animals which have been allowed to feed and move freely in healthy pastures (牧場) . 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 feed 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. Take, for example, the question of sugar. This is actually a non-essential food! Although a natural alternative like honey can be used to sweeten food if necessary, we can in fact do without it. It is rat that sugar is harmful in itself. But it does seem to be an additive. The quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is to provide us with energy, in the form of calories. There are no vitamins in it, no minerals and no fibre (纖維).

　　It is significant that nowadays fibre is considered to be an important part of a healthy diet. In white bread, for example, the fibre has been removed. But it is present in unrefined flour and of course in vegetables. It is interesting to note that in countries where the national diet large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Therefore the emphasis is placed on the eating of wholemeal(全麥) bread and more vegetables by modern experts on“healthy eating”.

Answer 1

答案：A;B;B;D;C
解析：

1．A　　導解：文中提到人們改變飲食習慣的原因是很多食品對身體無益，于是人們尋找不含化學添加劑，沒有化肥污染的天然食品。從文中的描述可知，這是表明人們對健康更關(guān)注。 　　2．B　　導解：從第二段的講述可知，富含有機物的土壤指其中含有“unused”蔬菜物質(zhì)，即B． 　　3．B　　導解：關(guān)于養(yǎng)雞場的雞，文中說它們上千只關(guān)在一起（A），吃的簡直像垃圾（C），這樣喂養(yǎng)的雞肉沒味，蛋缺少足夠的維生素（D）；在健康的牧場自由放牧的動物也是天然食品。 　　4．D　　導解：關(guān)于糖，文中提到它本身無害（A錯），給人體提供熱量（C錯），里面沒有維生素，沒有礦物質(zhì)等。至于B項，文中說糖只是一種additive，還可有天然的替代品，B項說法不對，We can do without it（沒有也行），綜合分析選D． 　　5．C　　導解：全文講述人們對健康食品的追求，天然食品包括哪些種類，健康飲食，糖對人體的作用應該怎么認識，以及健康食品中的纖維等，C項最具概括性。
