单选题Change—or the ability to adapt oneself to a changing environment—is essential to evolution. The farmer whose land is required for housing or industry must adapt himself: he can move to an-other place and master the problems peculiar to it; he can change his occupation, perhaps after a period of training; or he can starve to death. A nation which cannot adapt its trade or defense requirements to meet world conditions faces economic or military disaster. Nothing is fixed and permanently stable. There must be movement forward, which is progress of a sort, or movement backwards, which is decay and deterioration. In this context, tradition can be a force for good or for evil. As long as it offers a guide, it helps the ignorant and the uninformed to take a step forward and, thereby, to adapt themselves to changed circumstances. Tradition, or custom, can guide the hunter as effectively as it can influence the nervous hostess. But if we make an idol (偶像) of tradition, it ceases to become a guide and becomes an obstacle lying across the path of change and progress. If we insist on trying to plot the future by the past, we clearly handicap ourselves and invite failure. The better course is to accept the help which tradition can give, but realizing that it necessarily has its roots in the past, to be well aware of its limitations in a changing world.

单选题 "Much of the sickness and death attributed to the major communicable (可传染的) diseases is in fact caused by malnutrition (营养不良) which makes the body less able to withstand infections when they strike," said Dr. Hiroshi Nakajima, Director-General of the World Health Organization (WHO). "At the same time," he added, "in developing countries today, malnutrition is the cause of 174 million children under five years of age being underweight, and 230 million being stunted in their growth. Such figures represent deprivation, suffering and wasted human potential on a scale that is unacceptable from every point of view. Whether we think in terms of humanitarian concern, common justice or development needs, they demand a response, both from national governments and from the international community. " WHO, working closely with its member states, other United Nations agencies and nongovernmental organizations, is focusing on major crippling (致残的) forms of malnutrition, such as protein-energy malnutrition, vitamin A deficiency (缺乏，不足). At the end of January 1996, 98 countries had national plans of action for nutrition and 41 countries had one under preparation, in keeping with their commitments made at the International Conference on Nutrition in Rome December 1992. The global situation, however, remains grim. Over 800 million people around the world still cannot meet basic needs for energy and protein, more than two thousand million people lack essential micro-nutrients, and hundreds of millions suffer from diseases caused by unsafe food or unbalanced diets. It is now recognized that 6. 6 million out of the estimated 12.2 million deaths annually among children under five—or 54% of young child mortality (死亡率) in developing countries—is associated with malnutrition In addition to the human suffering, the loss in human potential translates into social and economic costs that no country can afford. In 1990, only 53 developing countries had reliable data on the number of young children under weight; by 1995, 97 countries had such data, nearly all of which included information on stunting and wasting. In some regions, such as sub-Saharan Africa and south Asia, stagnation of nutritional improvement combined with a rapid rise in population has resulted in an actual increase in the total number of malnourished children. Currently, over two-thirds of the world's malnourished children live in Asia (especially south Asia). followed by Africa and Latin America.

单选题 In 1998 consumers could purchase virtually anything over the Internet. Books, compact discs, and even stocks were available from World Wide Web sites that seemed to spring up almost daily. A few years earlier, some people had predicted that consumers accustomed to shopping in stores would be reluctant to buy things that they could not see or touch in person. For a growing number of time-starved consumers, however, shopping from their home computer was proving to be a convenient alternative to driving to the store. A research estimated that in 1998 U. S. consumers would purchase $7.3 billion of goods over the Internet, double the 1997 total. Finding a bargain was getting easier, owing to the rise of online auctions and Web sites that did comparison shopping on the Internet for the best deal. For all the consumer interest, retailing in cyberspace was still a largely unprofitable business, however. Internet pioneer Amazon.com, which began selling books in 1995 and later branched into recorded music and videos, posted revenue of $153.7million in the third quarter, up from $37.9 million in the same period of 1997. Overall, however, the company's loss widened to $45.2 million from $9.6 million, and analysts did not expect the company to turn a profit until 2003. Despite the great loss, Amazon. com had a stock market value of many billions, reflecting investors' optimism about the future of the industry. Internet retailing appealed to investors because it provided an efficient means for reaching millions of consumers without having the cost of operating conventional stores with their armies of salespeople. Selling online carried its own risks, however. With so many companies competing for consumers' attention, price competition was intense and profit margins thin or nonexistent. One video retailer sold the hit movie Titanic for $9.99, undercutting (削价) the $19.99 suggested retail price and losing about $6 on each copy sold. With Internet retailing still in its initial stage, companies seemed willing to absorb such losses in an attempt to establish a dominant market position.
