单选题{{B}}Text 3{{/B}} 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 the 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 a-mount—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 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 wholemeal bread and more vegetables by modem experts in "healthy eating".

单选题Obviously television has both advantages and disadvantages. In the first place, television is not only a convenient source of entertainment, but also a comparatively cheap one. With a TV set in the family people don't have to pay for expensive seats at the theatre, the cinema, or the opera. All they have to so is to push a button or turn a knob, and they can see plays, films, operas and shows of every kind. Some people, however, think that this is where the danger lies. The television viewers need do nothing. He does not even have to use his legs if he has a remote control. He makes no choice and exercises, no judgment. He is completely passive and has everything presented to him without any effort on his part. Television, it is often said, keeps one informed about current events and the latest developments in science and politics. The most distant countries and the strangest customs are brought right into one's sitting room. It could be argued that the radio performs this service as well; but on television everything is much more living, much more real. Yet here again there is a danger. The television screen itself has a terrible, almost physical charm for us. We get so used to looking at the movements on it, so dependent on its pictures, that it begins to control our lives. People are often heard to say that their television sets have broken down and that they have suddenly found that they have far more time to do things and that they have actually begun to talk to each other again. It makes one think, doesn't it? There are many other arguments for and against television. We must realize that television itself is neither good nor bad. It is the uses that it is put to that determine its value to society.

单选题 The way people hold to the belief that a fun-filled, painfree life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness, then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not, things that lead to happiness involve some pain. As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment(承担的义务), self-improvement. Ask a bachelor(单身汉)why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features. Couples with infant children are lucky to get a whole night' s sleep or a three-day vacation. I don' t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.

单选题{{B}}Text 3{{/B}} The potential of computers for increasing the control of organizations or society over their members and for invading the privacy of those members has caused considerable concern. The privacy issue has been raised most insistently with respect to the creation and maintenance of data files that assemble information about persons from a multitude of sources. Files of this kind would be highly valuable for many kinds of economic and social research, but they are bought at too high a price if they endanger human freedom or seriously enhance the opportunities of blackmailers. While such dangers should not be ignored, it should be noted that the lack of comprehensive data files has never before been the limiting barrier to the suppression of human freedom. Making the computer the villain in the invasion of privacy or encroachment on civil liberties simply diverts attention from the real dangers. Computer data bank files can and must be given the highest degree of protection from abuse. But we must be careful also, that we do not employ such crude methods of protection as to deprive our society of important data it needs to understand its own social process and to analyze its problems. Perhaps the most important question of all about the computer is what it has come and will do to man's view of himself and his place in the universe. The most heated attacks on the computer are not focused on its possible economic effects, its presumed destruction of job satisfaction, or its threat to privacy and liberty, but upon the claim that it causes people to be viewed, and to view themselves, as machines. What the computer and the progress in artificial intelligence challenge is an ethic that rests on man's apartness from the rest of nature. An alternative ethic, of course, views man as a part of nature, governed by nature law, subject to the forces of gravity and the demands of man's body. The debate is about artificial intelligence and the demands of man's body. The debate is about artificial intelligence and the stimulation of man's thinking is, in considerable part, a confrontation of these two views of man's place in the universe.
