Natural foods make up a small part of organic foods.A．YB．NC．NG

ver conventionally grown and marketed food products are now being debated. Advocates of organic foods frequently proclaim that such products are safer and more nutritious than others.

The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the greater number of written material advancing such claims make it difficult for the general public to sep arate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form. the basis for folklore.

Almost daily the public is surrounded by claims for "no-aging" diets, new vitamins, and other wonder foods. There are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that crops grown with organic fertilizers are nutritionally superior to chose with chemical fertilizers, that untreated grains are better than fumigated grains, and the like.

One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern ff consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.

The author implies that there is cause for concern if consumers with limit ed incomes buy organic foods instead of conventionally grown foods be cause ______ .

A．organic goods can be more expensive but are often no better than conventionally grown foods

B．many organic foods are actually less nutritious than similar conventionally grown foods

C．conventionally grown foods are more readily available than organic foods

D．too many farmers will stop using conventional methods to grow food crops

Which of the following is a reason for people' s growing interest in natural foods？

A．They want to return to nature.

B．They want to eat all kinds of foods.

C．Natural foods are very delicious.

D．They are more health conscious.

Natural Resources

Throughout history, people have often selected where they want to live based on the natural resources that are available in the area.26 Some of these resources include water, food sources such as fruits and vegetables, and animals that can be caught or hunted.

A region’s natural resources determine the way of life of its people.27 |On the other hand，poor soil will either send people looking for better places, or attract people with other purposes for the land, such as setting up businesses or factories.

28 People who wish to make a living as fishermen can do so by the pcean, but cannot do so in the desert.Desert people have many traditional and |mique foods, which cannot be found in the forest.Each area attracts people based on their interests and purposes.

Areas that have rich water resources will naturally have more people, frraditionally, villages，towns and cities built near water have been the most luccessful.People there are able to use the water resources to meet their daily lieeds.29 Places that are hard to reach，such as high mountains or dry Beserts, will have fewer people living in them.

30 For too long, people have destroyed natural resources, using up those [resources that cannot be easily replaced.On the earth, we are lucky to have many resources that are renewable, such as sun, wind, water, and trees.As more and more focus is placed on the use of renewable resources, it will become easier to |＞rotect our planet from further harm.

A.It is easy to find new resources in nature.

B .Renewable resources are those that can be replaced easily.

c.While you may not think of oceans as natural resources, they are.

D .for example, regions with rich soil can support fanning societies.

E .They can also use the water to help them move goods to other areas.

F.Natural resources are useful to people, and they come from the earth.

Increasingly, over the past ten years, people—especially young people—have become aware of the need to change their eating habit, because much of the food they eat, particularly processed foods, is not good for 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 vegetable, fruit and grain which have been grown in soil and are 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 fanning 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 farm, 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. Take, for example, the question of sugar. This is actually a nonessential food ! Although a natural alternative, such as honey, can be used to sweeten food if it is necessary, we can in fact do without it. It is not that sugar is harmful in itself. But it does seem to be addictive: 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.

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 contains large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Hence the emphasis is placed on the eating of whole meal bread and more vegetables by modem experts in "healthy eating".

species of plant and several hundreds thousands types of living things. But only a tiny percentage of these were ever domesticated. Modern shops have hastened a trend towards specialization which began in the earliest days of agriculture. The food of the rich countries has become cheaper relative to wages. It is speedily distributed in supermarkets. But the choice annually becomes less and less great. Even individual foods themselves become more standardized. We live in the world of carrot specially blunted in order to avoid making a hole in the bag, and the tomato grown to meet a demand for a standard weight of weighting tomatoes to a kilo. Siri von Reis asks: "Only the three major cereals （谷物类食物） and perhaps ten other widely cultivated species stand between famine and survival for the world's human population and a handful of drug plants has served Western civilization for several thousand years. A rather obvious question arises: Are we missing something？" After all, there are 800 000 species of plant on earth.

听力原文： Health food is a general term applied to all kinds of food that are considered more healthful than the types of foods widely sold in supermarkets. For instance, whole grains, fried beaus, and corn oil are health foods. A narrower classification of health food is natural food, which is used to distinguish between types of the same food. Raw honey is a natural sweetener, whereas relined sugar is not. Fresh fruit is a natural food, but canned fruit, with sugars and other additives, is not. The most precise term of all and the narrowest classification within health food is organic food, which is used to describe food that has been grown on a particular kind of farm. Fruits and vegetables that are grown in gardens that are only treated with organic fertilizers, that are not sprayed with poisonous insecticides, and that are not refined after harvest, are organic foods. Meats, fish, dairy and poultry products from animals that are fed only organically-grown feed and that are not injected with hormones are organic foods.

In choosing the type of food you eat, then, you have basically two choices: inorganic, processed foods, or organic, unprocessed foods. A wise decision should include investigation of the claims that processed foods contain chemicals, some of which ate proven to be poisonous, and that vitamin content is greatly reduced in processed foods.
