单选题There are four basic types of competition in business that form a continuum from pure competition through monopolistic competition and oligopoly (商品供应垄断) to monopoly. At one end of the continuum, pure competition results when every company has a similar product. Companies that deal in commodities such as wheat or corn are often involved in pure competition. In pure competition, it is often the ease and efficiency of distribution that influences purchase. In contrast, in monopolistic competition several companies may compete for the sale of items that may be substituted. The classic example of monopolistic competition is coffee and tea. If the price of one is perceived as too high, consumers may begin to purchase the other. Coupons and other discounts (折扣) are often used as part of a marketing strategy to influence sales. Oligopoly occurs when a few companies dominate the sales of a product or service. For example, only five airline carriers control more than 70 percent of all ticket sales in the United States. In oligopoly, serious competition is not considered desirable because it would result in reduced revenue for every company in the group. Although price wars do occur, in which all companies offer substantial savings to customers, a somewhat similar tendency to raise prices simultaneously is also usual. Finally, monopoly occurs when only one firm sells the product. Some monopolies have been tolerated for producers of goods and services that have been considered basic or essential, including electricity and water. In these cases, it is government control, rather than competition, that protects and influences sales.

单选题These days we hear a lot of nonsense about the "great classless society". The idea that the twentieth century is the age of the common man has become one of the great cliches of our time. The same old arguments are put forward in evidence. Here are some of them: monarchy as a system of government has been completely discredited. The monarchies that survive have been deprived of all political power. Inherited wealth has been savagely reduced by taxation and, in time, the great fortunes will disappear altogether. In a number of countries the victory has been complete. The people rule; the great millennium has become a political reality. But has it? Close examination doesn't bear out the claim. It is a fallacy to suppose that all men are equal and that society will be leveled out if you provide everybody with the same educational opportunities.(It is debatable whether you can ever provide everyone with the same educational opportunities, but that is another question.)The fact is that nature dispenses brains and ability with a total disregard for the principle of equality. The old rules of the jungle, "survival of the fittest" , and "might is right" are still with us. The spread of education has destroyed the old class system and created a new one. Rewards are based on merit. For "aristocracy" read "meritocracy" ; in other respects, society remains unaltered: the class system is rigidly maintained. Genuine ability, animal cunning, skill, the knack of seizing opportunities, all bring material rewards. And what is the first thing people do when they become rich? They use their wealth to secure the best possible opportunities for their children, to give them " a good start in life". For all the lip service we pay to the idea of equality, we do not consider this wrong in the western world. Private schools which offer unfair advantages over state schools are not banned because one of the principles in a democracy is that people should be free to choose how they will educate their children. In this way, the new meritocracy can perpetuate itself to a certain extent; an able child from a wealthy home can succeed far more rapidly than his poorer counterpart. Wealth is also used indiscriminately to further political ends. It would be almost impossible to become the leader of a democracy without massive financial backing. Money is as powerful a weapon as ever it was. In societies wholly dedicated to the principle of social equality, privileged private education is forbidden. But even here people are rewarded according to their abilities. In fact, so great is the need for skilled workers that the least able may be neglected. Bright children are carefully and expensively trained to become future rulers. In the end, all political ideologies boil down to the same thing: class divisions persist whether you are ruled by a feudal king or an educated peasant.

单选题There is extraordinary exposure in the United States to the risks of injury and death from motor vehicle accidents. More than 80 percent of all households own passenger cars or light trucks and each of these is driven an average of more than 11,000 miles each year. Almost one-half of fatally injured drivers have a blood alcohol concentration (BAC) of 0.1 percent or higher. For the average adult, over five ounces of 80 proof spirits would have to be consumed over a short period of time attain these levels. One third of drivers who have been drinking, but fewer than 4 percent of all drivers, demonstrate levels. Although less than 1 percent of drivers with BACs of 0.1 percent or more are involved in fatal crashes, the probability of their involvement is 27 times higher than for those without alcohol in their blood. There are a number of different approaches to reducing injuries in which intoxication plays a role. Based on the observation that excessive consumption correlates with the total alcohol consumption of a country's population, it has been suggested that higher taxes on alcohol would reduce both. While the heavier drinkers would be taxed the most, anyone who drinks at all would be penalized by this approach. To make drinking and driving a criminal offense is an approach directed only at intoxicated drivers. In some states, the law empowers police to request breath tests of drivers cited for any traffic offense and elevated BAC can be the basis for arrest. The National Highway Traffic Safety Administration estimates, however, that even with increased arrests, there are about 700 violations for every arrest. At this level there is little evidence that laws serve as deterrents to drinking while intoxicated. In Britain, motor vehicle fatalities fell 25 percent immediately following implementation of the Road Safety Act in 1967. As the British increasingly recognized that they could drink and not be stopped, the effectiveness declined, although in the ensuing three years the fatality rate seldom reached that observed in the seven years prior to the Act. Whether penalties for driving with a high BAC or excessive taxation on consumption of alcoholic beverages will deter the excessive drinkers responsible for most fatalities is unclear. In part, the answer depends on the extent to which those with high BACs involved in crashes are capable of controlling their intake in response to economic or penal threat. Therapeutic programs which range from individual and group counseling and psychotherapy to chemotherapy constitute another approach, but they have not diminished the proportion of accidents in which alcohol was a factor. In the few controlled trials that have been reported there is little evidence that rehabilitation programs for those repeatedly arrested for drunken behavior have reduced either the recidivism or crash rates. Thus far, there is no firm evidence that Alcohol Safety Action Project supported programs, in which rehabilitation measures are requested by the court, have decreased recidivism or crash involvement for clients exposed to them, although knowledge and attitudes have improved. One thing is clear, however: unless we deal with automobile and highway safety and reduce accidents in which alcoholic intoxication plays a role, many will continue to die.
