单选题There is much discussion today about whether economic growth is desirable at an earlier period; our desire for material wealth may have been justified. Now, however, this desire for more than we need is causing serious problems. Even though we have good intentions, we may be producing too much, too fast. Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. There include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world"s population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease. People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization. This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them with one another. We may infer from the context that "Proponents" (Para. 3) most probably means ______.

单选题{{B}}26-30{{/B}} While still in its early stages, welfare reform has already been judged a great success in many states, at least in getting people off welfare. It's estimated that more than 2 million people have left the rolls since 1994. In the past four years, welfare rolls in Athens County have been cut in half. But 70 percent of the people who left in the past two years took jobs that paid less than $6 an hour. The result: The Athens County poverty rate still remains at more than 30 percent—twice the national average. For advocates (代言人) for the poor, that's an indication much more needs to be done. "More people are getting jobs, but it's not making their lives any better," says Kathy Lairn, a policy analyst at the Center on Budget and Policy Priorities in Washington. A center analysis of U.S. Census data nationwide found that between 1995 and 1996, a greater percentage of single, female-headed households were earning money on their own, but that average income for these households actually went down. But for many, the fact that poor people are able to support themselves almost as well without government aid as they did with it is in itself a huge victory. "Welfare was a poison. It was a toxin (毒素) that was poisoning the family," says Robert Rector, a welfare-reform policy analyst. "The reform is changing the moral climate in low-income communities. It's beginning to rebuild the work ethic (道德观), which is much more important." Mr. Rector and others argued that once "the habit of dependency is cracked", then the country can make other policy changes aimed at improving living standards.

单选题Sport is heading for an indissoluble marriage with television and the passive spectator will enjoy a private paradise. All of this will be in the future of sport. The spectator (the television audience) will be the priority and professional clubs will have to readjust their structures to adapt to the new reality: sport as a business. The new technologies will mean that spectators will no longer have to wait for broadcasts by the conventional channels. They will be the ones who decide what to see. And they will have to pay for it. In the United States the system of the future has already started: pay-as-you-view. Everything will be offered by television and the spectator will only have to choose. The review Sports Illustrated recently published a full profile of the life of the supporter at home in the middle of the next century. It explained that the consumers would be able to select their view of the match on a gigantic, flat screen occupying the whole of one wall, with images of a clarity which cannot be foreseen at present; they could watch from the trainer"s bench, from the stands just behind the batter in a game of baseball or from the helmet of the star player in an American football game. And at their disposal will be the same options the producer of the recorded program has: to select replays, to choose which camera to use and to decide on the sound-whether to hear the public, the players, the trainer and so on. Many sports executives, largely too old and too conservative to feel at home with the new technologies, will believe that sport must control the expansion of television coverage in order to survive and ensure that spectators attend matches. They do not even accept the evidence which contradicts their view: while there is more basketball than ever on television, for example, it is also certain that basketball is more popular than ever. It is also the argument of these sports executives that television is harming the modest team. This is true, but the future of those teams is also modest. They have reached their ceiling. It is the law of the market. The great events continually attract larger audience. The world is being constructed on new technologies so that people can make the utmost use of their time and, in their home, have access to the greatest possible range of recreational activities. Sport will have to adapt itself to the new world. The most visionary executives go further. Their philosophy is: rather than see television take over sport, why not have sports take over television?

单选题Every time a person eats something he makes a nutritional decision. He accepts or rejects the food available to him at home for meals or snacks. Or he selects food for himself at many places in the community, such as supermarkets, drive-ins, restaurants, and food counters in drug stores. (83) These selections make a difference in how an individual looks, how he feels, and how well he can work and play. When a good assortment of food in appropriate amounts is selected and eaten, the consequences are more likely to be a desirable level of health and enough energy to allow one to be as active as he needs and wants to be. When choices are less than desirable, the consequences are likely to be poor health or limited energy or both. Studies of diets of individuals in the United States show that food selection is a highly individual matter, even among young children. (84) Furthermore, far too many individuals of all ages are making poor choices day after day and are either now living with the consequences or will be in the future. Nutritionists and workers in allied professions have been concerned about helping people learn to select and enjoy a wide variety of food combinations that can add up to a good diet. Most people believe that they are well-fed—that the choices they make are good ones. After all, they are not really sick; neither are they hungry. However, their nutrition is really poor in one respect or another. Milk and milk products, such as cheese, icecream, buttermilk, and yogurt, are often neglected. Then people may leave out in their diets many fruits and vegetables, particularly those that are good sources of vitamins A and C. These include dark green, leafy vegetables; deep yellow vegetables; and citrus fruits and vegetables, such as cabbages, tomatoes, and green peppers.
