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 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 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 this 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 wholemeal bread and more vegetables by modem experts in "healthy eating".
This passage is mainly concerned with_________.
A．people' s growing interest in natural foods
B．natural food and health diet
C．the importance of fibre in foods
D．harmful effects of sugar

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.

Why should this be？ It's because he's not using his heating ability to help him remember and understand what he's been taught.
Some children get into the habit of learning and remembering things by what they hear. They've got good hearing memories. Other children find it easier to learn and remember things by what they see. They've got good seeing memories. Some children have equally good ability at both seeing and hearing in learning things. Others, less fortunate, seem to have poor hearing and seeing-memories. Most children, I'd say, unknowingly prefer one method over the other for learning and remembering.
But this favoring of one sense over the other is a bad habit and deprives (使......不能) the child of the full use of his natural senses. Mrs. Alien was clearly incredulous when I told her there was nothing wrong with her son's heating. "But he never seems to really understand what he hears, that's what his teachers tell me," she said.
"My psychological examination of William shows he's weak in his hearing memory," I said, "but he has perfectly normal intelligence and can learn in school."
"Our family doctor examined William and he says the boy's hearing was all right. So, that proves you're right on that point," admitted Mrs. Alien. "So how can we help him？ My husband and I will do anything you say, Dr. Dursteln."
"You can do a lot to improve William's hearing memory, but it'll take time. You must be patient and not expect results immediately." I cautioned.
I suggested a detailed program for the parents to use at home. I told Mrs. Alien to come back and see me every two weeks so that I could guide her in any problem she had in using my program.
Those who have poor hearing memories______.
A．cannot hear sounds clearly
B．are poor at remembering and understanding what they have learned
C．are poor at learning things by what they have heard
D．have the habit of learning things by what they have heard of

Poorer countries could of course introduce domestic laws to curb the promotion of smoking. But such measures face tough opposition from the tobacco industry and those sectors funded by tobacco sponsorship, from sports to culture. A survey of 400 recent films released by India's "Bollywood" found that 320 had scenes involving smoking, usually presenting it in a positive way. If such countries had an international treaty obligation to control tobacco use, it might strengthen their health ministries' hands in overcoming the tobacco lobbyists'(说客) influence on domestic politics.
International agencies like the World Bank are convinced that higher taxes will curb tobacco use, though there is not much evidence to support this. Given their dependence on tobacco revenues, it is unlikely that finance ministers and state treasurers around the world would be so enthusiastic about increasing taxes if they really thought it would lead to smokers quitting en masse (全体地).
According to the passage, which of the following statements is NOT true？
A．In rich countries people are becoming more aware of the health risks of cigarettes and smokers are starting to quit.
B．More than half of the smokers in the world are in Asia.
C．More and more people in poorer countries are getting into the habit of smoking.
D．Despite years' cigarette advertising restrictions in rich countries, cigarette sales worldwide are ever increasing.

When did Seward buy Alaska from the Russians？
A．In 1869.
B．In 1959.
C．In 1867.
D．In 1872.
第10题
听力原文： Alaska, which was called Russian America before it was sold to the United States, joined the Union as the forty-ninth state in 1959. (Hawaii was the fiftieth state to join the Union. ) Alaska is now the largest of all the 50 states in the U.S.
It was in 1867 that President A. Johnson's Secretary of State, Seward, bought Alaska from the Russians at a cost of $ 7.2 million. The buying of the huge northern land mass seemed at first something foolishly done. Nor only was Alaska difficult to reach, but it was also hard to live in, and it appeared to have no importance in times of war. Besides, there are volcanoes there as Alaska lies on the Pacific "ring of fire." In Alaska, large treeless areas are covered with snow all the year round. For these reasons the buying of Alaska was called "Seward's Folly" at that time.
However, in 1896 gold was found in Alaska, and people poured into the land quickly. Since then other important natural resources were discovered, including oil. Soon, people changed their thinking about "Seward's Folly".
But most people visit Alaska in order to see the endless beauty of nature that the northern land discloses to them. For instance, there are about 11,000 islands in Alaska. And in a certain area of Alaska, the sun does not set for 82 days every year.
