The way a meal is cooked and served is most important and an attractively served meal will often improve a child's appetite.

At meal times it is a good (36) to give a child a small portion and let him come back for a second helping rather than give him as (37) as he is likely to eat all at once. Do not talk too much to the child (38) meal times, but let him get on with his food; and do not (39) him to leave the table immediately after a meal or he will soon learn to swallow his food so he can hurry back to his toys.

单选题{{B}}练习十五{{/B}} It's almost the end of summer for the first annual contest to choose the best operating monopoly in America. Five contestants are selected. Each exhibits fine monopolistic characteristics and is worthy of serious consideration for the award. The U.S. Postal Service claims to be the longest-running monopoly and has the distinction of having its control over First Class mail prescribed by the Constitution. The monopoly has preserved large flows of revenues and high wage rates despite studies showing that private companies could carry the mail more efficiently at much lower cost. On the other hand, the position of the Postal Service has been eroded: first, by successful competition on package delivery; second, by the recent entry of express delivery services; and third, and potentially most damaging, by the introduction of the fax machine. Since faxes are bound to supplant(取代) a substantial fraction of First Class letters, the failure to get Congress to classify a fax as First Class mall and, hence, the exclusive domain of the post office shows a remarkable loss of political muscle. Thus, despite past glories, it is hard to be sanguine(乐观的) about the long-term prospects of the post office as a flourishing monopoly. OPEC was impressive in generating billions of dollars for its members. To understand the functioning of this cartel(卡特尔) it's important to sort out the good guys from the bad. Saudi Arabia and Kuwait have typically held oil production below capacity and thereby kept prices above the competitive level. While Libya and Iraq have produced as much as they could and thereby kept prices low. The former were responsible for the vast expansion of oil revenues. But unfortunately, these countries could not keep the other OPEC members in line and were also able to exclude new producers or prevent conservation by consumers. Most cable TV companies have government-issued licenses that keep competitors out. Thus, this business supports the hypothesis that private monopolies aren't sustainable for long unless they have the weight of government behind them. The rapid escalation of prices and the limitations on services seem, however, to be getting customers and their congressional representatives progressively more annoyed. Thus, it would not be surprising if legislative action leads soon to a deterioration of the cable companies' monopoly power. Officials of Ivy League universities have been able to meet in semi-public forums to set rules that determine prices of admission as a function of applicant characteristics, especially financial resources. The universities have more or less successfully applied a high moral tone to the process: Rich applicants are charged more than the competitive price for schooling in order to subsidize(补贴) the smart poor, but it is unclear why this subsidy should come from the smart rich rather than from taxpayers in general. In any event, the universities' enviable cartel position has been damaged by the unenlightened Justice Department. 'Since most of the universities involved have agreed to stop these practices, it may be that future prices for private higher education will come closer to being competitively determined. The final contestant, the NCAA, has been remarkably successful in holding down "salaries" paid to college athletes. It would be one thing merely to collude to determine price ceilings, but the NCAA has also managed to monopolize all the moral arguments. The NCAA has the much more difficult task of defending a policy that prevents many poor individuals from earning money. Incredibly, this defense has been so successful that it has even allowed the organization to maintain the moral high ground. When the NCAA maintains its cartel by punishing schools that violate the rules, almost no one doubts that the evil entities are the schools or people who paid the athletes, rather than the cartel enforcers who prevented from getting paid: Given this extraordinary balancing act, the decision of the panelists was straightforward and the NCAA is the clear and deserving winner of the first annual prize for the best monopoly in America.

单选题Besides active foreign enterprises and a (31) number of private employers, a consequential new development was the development of employment in state-owned enterprises (guanying or guanshang). Started by some (32) Qing officials, the yangwupai, in the late nineteenth century, sizable state-owned enterprises developed primarily (33) enhancing China's national defense. Famous industrial giants of today's China such as the shipyards in Shanghai and heavy industries in cities like Wuhan, Nanjing, and Chongqing were built by the Qing or the Republic governments. Some of them later began to (34) considerable private investment. After World War Ⅱ, this type of state-owned employment became very important. Labor in those enterprises consisted basically (35) two tiers: a largely market-oriented allocation of blue-collar and some white-collar workers, and a mostly state allocation of most of the white-collar workers including managerial and technical personnel. The latter was a distorted labor market that featured strong (36) considerations in allocating and managing labor. Personal and kinship connections, the so-called "petticoat influence," and political (37) were the norm for this type of labor allocation pattern. In a way, it was midway between a rather crude market-oriented labor allocation pattern and the centuries-old, warm, family-based traditional labor allocation pattern. It covered a very small but important portion of the Chinese labor force, and thus (38) our attention. Later, it apparently provided the historical precedent (39) state-owned enterprises to allocate their administrative and technical cadres, even its entire industrial labor force, (40) state employees.

单选题We arranged that Kissinger would fly to Vietnam for talks early in July and then stop in Pakistan on the way back. There he would develop a stomachache that would require him to stay in Pakistan on the way back. Then, with President Yahya's cooperation he would be taken to an airport where a Pakistani plane would fly him over the mountains to China. Kissinger's trip was given the code (密码) named Polo after Marco Polo, another Western traveler who made history by journeying to China. Everything went without a hitch. His slight illness in Islamabad received only minor attention from reporters covering him. They accepted the story that he would be confined to bed for at least a couple of days and began making arrangements for their own entertainment. Because of the need for complete secreey and the lack of any direct communication facilities between Beijing and Washington, I knew that we would have no word from Kissinger while he was in China. Even after he had returned to Pakistan it would still be important to maintain secrecy. So before Kissinger left, we agreed on a single code word--Eureka--which he would use if his mission were successful. On July 11, A1 Haig, who knew our code word, phoned me to say that a cable from Kissinger had arrived. "What's message?" I asked. "Eureka," he replied.

单选题{{B}}Passage One{{/B}} As they grow older, most people wonder how increasing age will affect intelligence. Can people in middle age and beyond expect to think as effectively and to solve problems as efficiently as they have in the past? One of the difficulties in comparing the intellectual functioning of people at different ages is the problem of cohort((具有相同特征的)一群人) effects. Different age groups in the population have experienced different historical events (wars, exposure to television, and so on) as well as changes in the general standard of living. Different scores that people of varying ages achieve on intelligence tests could be partly due to changes in diet, housing, or health care or, even more likely, to the amount and quality of education. Since the beginning of this century, there has been a trend for more people to go to school and to remain in school longer. Because it eliminates these cohort effects, a longevous (长寿的) study may be the best way to look at age-related changes in intellectual functioning. One of the few longevous studies of intellectual functioning is the Seattle Longevous Study, conducted by K. Warner Schaie and his associates. The original subjects, who ranged in age from 18 to 67, have now been tested 4 times over a 21 year period. These results have given a reasonably good picture of longitudinal(纵向的) change in cognitive abilities. The data show that there are only trivial changes in the kinds of abilities measured by intelligence tests before the age of 60, and no reliable decrease can be shown in these abilities before age 74. Although there is some decrease in measured ability in the late 60s and the 70s, it is not until age 81 that the average person falls below the middle range of performance for young adults. The data from the Seattle Longevous Study also suggest that there are very great individual differences in intellectual change throughout adulthood. Between the ages of 74 and 81, less than half the subjects showed any significant change. One important factor is health, especially the presence or absence of coronary(冠状) heart disease. Another is a high socioeconomic status, which is related not only to higher initial levels of functioning but to the maintenance of a higher level throughout life. A flexible life style in middle age, probably associated with a flexible personality style, also tends to predict high performance in old age. While some of these variables may have substantial hereditary (遗传的) elements, changes in environment and education could also be important in maintaining a higher level of functioning for many individuals.

单选题The habits of those who constantly play video games are of great interest to people working in the video-game industry. If video games are going to be one of the most attractive features of future interactive television systems, it is important for manufacturers to know what types of games to produce, how best to present such games on interactive video, and how to ensure that such games maintain their fascination for people. Above all, it is essential to build up detailed profiles of people who are addicted to video games. Until recently, the chief market for video games has been boys aged 8 to 15. The fascination for interactive video games is seen in its purest form in this group. Video games appeal to some deep instinct in boys, who find it impossible to tear themselves away from them. Schoolwork is neglected, health is damaged, and even eating habits are affected. Girls of the same age, however, are entirely different, demonstrating far greater freedom from the hold of video games. Quite simply, they can accept and deal with video games easily, being able to play them when they want and then leave them alone. Aware of the reliance on boys of such a relatively narrow age group, some video-game manufacturers have tried to attract younger boys while others have concentrated on providing an older audience with an excuse to extend its game-playing habits into adulthood. These attempts have certainly had some success, though it must be admitted, of a fairly limited nature in comparison with the huge success of the 8 to 15 age group. No one has yet succeeded, however, in making video games attractive to the largest market of all: young adult women. These women buy more novels and watch more films and television dramas than any other single section of the population—but few show interest in video games.
