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."
According to this passage, people becoming interested in natural foods because ______.
A．they are getting fired of processed foods
B．they want to change their eating habits
C．a lot of the foods they eat is not healthy
D．food experts recommend them to have natural foods

(79) 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 ! 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 fiber.
(80) 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 quantifies 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

Your Bean Steak (素肉排), Sir!
What sort of food are we likely to be eating in the year 2000？
Most people, when you ask them a question like that, either say: " There won't be any left, " or "Whatever it is, there won't be much taste in it." Of course, there are good reasons for being worried about the world's food supplies in the future.Nevertheless, not all the experts share these worries.
For one thing, although the world's population is rising fast, food production is keeping pace with it, even in developing countries.It is therefore argued that the main reason why people are hungry is not that there is a world food shortage but that methods of cultivation are not sufficiently advanced in some areas and the food is not fairly distributed (分配 ).
This does not mean, however, that our diet (饮食 ) will go on being the same.In many industrialized countries, people feed animals with grain to produce high-quality beef, even though the grain would feed the human population, and use fishmeal to fatten pigs to improve the quality of bacon.While not many of us would like fishmeal for lunch, its nutritional value is high and the unattractive fish it is made from can be presented to the public in colorful packets of fish fingers.
By the year 2000, many of these problems will have been solved.Scientists are already capable of making steaks from soy beans.It is quite obvious that there will still be enough to eat, if we are not too particular about where the food comes from and what it is made of.
1.Most people believe that food supplies in the future().
A、will become a very serious problem
B、will be the same as they are today
C、will be enough in quantity but not good in quality
D、will be much better than they are today
2.The reason why people are hungry in today's world is().
A、poor farming methods and bad distribution
B、slow growth of food production
C、food shortages all across the world
D、fast rising population
3.The word "bacon" in Line 5, Para.3 most probably is().
A、a kind of "meat" made from grain
B、meat made from fish
C、food for fish
D、meat made from pigs
4.The word "particular" in Line 4, Para.4 means().
A、special
B、choosy
C、detailed
D、very exact
5.The title of this passage suggests that().
A、food in the future will be tasteless
B、there will be worldwide food shortages
C、diet in the future will be very different
D、science is making rapid progress
More and more people are realizing that there is a (54) between heart disease and the way they live. As a result of this new (55) , attitudes toward health are changing:In the past, people tend to think that it was sufficient for good health to have a good doctor who could be (56) on to know exactly what to do when they became ill. (57) they are realizing that merely receiving the best treatment (58) illness or injury "is not enough. They are learning that they must (59) more responsibility for their own health. Today many people are changing their dietary (60) and eating food with less fat and cholesterol(胆固醇). Many are paying more attention to reducing (61) in their lives. The number of smokers in the United States is now far below the level of twenty years ago because many people succeed in breaking the habit and as fewer people (62) it up. More and more are aware of the (63) of regular exercise like walking, running, or swimming, some have begun to walk or ride bicycles to work instead of made. Millions have become members of health clubs and have made health clubs one of the fastest growing businesses in the United States today. And now the (64) effects of these changing attitudes and behaviors are beginning to appear: a(n) (65) decrease in deaths from heart disease.

The riches of the sea yet to be developed by man ’s technology are impressive. Oil and gas explorations have existed for nearly thirty years. Valuable amounts of minerals such as iron, nickel and copper and so on exist on the ocean floor, ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish is an ancient skill practiced in the past mainly by Oriental peoples.
Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy such as hydroelectric power.
Technology is enabling man to explore ever deeper under the sea. The new undersea technology is providing divers with diving suits and undersea chambers that are kept at sea level pressure. The development of strong, new materials has made this possible.
The technology to harvest the sea continues to improve. By the year 2000, experts believe that the problems to exploit the food, minerals, and energy sources of the sea will be largely solved.
What is the best title for the passage？
A.Needs of .Man
B.Sources of..Energy
C.Sea Harvest
D.Sea Exploring Technology
According to the author, technology for exploring the sea is important because______.A.man cannot travel farther into space
B.resources on land are running short
C.it’s a lot of fun diving into the sea
D.ancient people used to explore the sea
Why does the author mention a steamship？A.To indicate that it is warmer in the ocean than on land.
B.To show that a steamship is better than other kinds of ship.
C.To argue that man should use steamships more than other means of transportation.
D.To illustrate that man can make use of sources of energy from the sea.
It can be inferred from the passage that_______.A.man hasn’t completely developed the riches of the sea
B.technology for exploring the sea has been solved
C.planting rice in the sea will be made possible in a short time
D.in the near future man can live on the ocean floor
