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 (有机的) 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(牧场). Compare this with what happens in the mass production of poultry: there are 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 lay 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! Al though 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 fiber.
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 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 on "healthy eating".
People have become more interested in natural foods because ________.
A．they are more health conscious
B．they want to taste all kinds of foods
C．natural foods are more delicious than processed foods
D．they want to return to nature

According to experts, the advantage of modified food is that it helps in preventing the occurrence of allergies and also has a long shelf life. However, a major portion of the population is against the consumption of genetically modified food and is concerned about its disadvantages. If you are also confused about the consumption of genetically modified food, read through the pros and cons given below and decide for yourself.
ADVANTAGES OF GENETICALLY MODIFIED FOODS
●One of the most prominent advantages of genetically modified food is that it helps in controlling the occurrence of certain diseases. Certain foods cause allergy to people. Their genetic modification alters the DNA system of these foods, thereby making them non-allergic.
●Another major advantage of such type of foods is that they grow faster than their traditionally grown counterparts. As a result, there is greater productivity and more food.
●A person need not bother about any additional costs, such as buying chemicals and pesticides, when it comes to genetically engineered food. The food is naturally pest-resistant.
●Farming these foods can be a great way to fight world hunger. Since these crops grow faster or more effectively, increased production would help countries wherein crops may not normally prosper because of less than desirable environmental conditions.
●The increased shelf life of these food products helps in reducing the quantity of rotten food.
DISADVANTAGES OF GENETICALLY MODIFIED FOODS
●The biggest disadvantage of genetically modified food is that they have harmful effects on the human body. The consumption of these genetically engineered foods can lead to development of diseases that are immune to antibiotics.
●Chances of developing cancer are high in people who regularly consume engineered food.
●Since it is an unnatural way of producing foods, there is an increased health hazard such as allergens, transfer of antibiotic resistance markers and unknown effects.
●Since the production of engineered food involves infusing animal genes in the crops and tampering with nature, it might not be good for consumption in the long run.
1. How does genetically modified food control the occurrence of certain diseases？{A; B; C}
A. By cross-pollinating.
B. By conventional crossbreeding.
C. By altering the DNA system of these foods.
2. Do farmers need to buy any chemicals and pesticides if they plant genetically modified food？{A; B; C}
A. Yes, they need to. Because the food is not resist to pests.
B. No, they don’t need to. Because the food is naturally pest-resistant.
C. No, they don’t need to. Because the chemicals and pesticides are provided by the government.
3. Which statement is not the advantage of genetically modified food？{A; B; C}
A. It may have harmful effects on human body.
B. Genetically modified food grows faster than their traditionally grown counterparts.
C. Farming genetically modified food can help fight world hunger.
4. What would happen to a person if he regularly consume genetically modified food？{A; B; C}
A. He would get cold.
B. He would lose some weight.
C. He would have cancer.
5. Which title is the best for this passage？{A; B; C}
A. Can genetically modified foods combat world hunger？
B. Genetically modified mood: our answer is no
C. Genetically modified foods: pros and cons

Natural foods, for example, vegetables, fruits and grains 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 ex- ample, 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.

A．these foods are fresh and sweet
B．they want to change their eating habits
C．these foods do not contain chemical additives and have not been affected by chemical fertilizers
D．they don't like the processed foods

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(添加剂) and which have not been affected by chemical fertilizers, widely used in farming today.
