单选题 I doubt that any historically valid treatment of that presidential administration can emerge for at least another decade, if then. I confess that when I came out of the White House I signed up to do an "insider volume", but sober, professional second thoughts have led me to put that project on ice until at least 1980. The problem is that I simultaneously know too much, and not enough. I know what I thought was happening. But I cannot fully document what happened. And I have seen enough highly classified documents to know that most of what the observers thought was happening was at best haft right, at worst dead wrong. This has steered me in a different direction as far as writing is concerned. I am now preparing what is frankly and unashamedly an ex parte memoir, "My Experiences in Washington." It is based on what I believed to be true, on the picture as I conceptualized it, of the presidential administration under which I worked.

单选题{{B}}16-20{{/B}} President Coolidge's statement, "The business of America is business," still points to an important truth today--that business institutions have more prestige (威望) in American society than any other kind of organization, including the government. Why do business institutions possess this great prestige? One reason is that Americans view business as being more firmly based on the ideal of competition than other institutions in society. Since competition is seen as the major source of progress and prosperity by most Americans, competitive business institutions are respected. Competition is not only good in itself, it is the means by which other basic American values such as individual freedom, equality of opportunity, and hard work are protected. Competition protects the freedom of the individual by ensuring that there is no monopoly (垄断) of power. In contrast to one, all-powerful government, many businesses compete against each other for profits. Theoretically, if one business tries to take unfair advantage of its customers, it will lose to competing business which treats its customers more fairly. Where many businesses compete for the customers' dollar, they cannot afford to treat them like inferiors or slaves. A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it is more supportive of freedom than government, even though government leaders are elected by the people and business leaders are not. Many Americans believe, then, that competition is as important, or even more important, than democracy in preserving freedom. Competition in business is also believed to strengthen the ideal of equality of opportunity. Competition is seen as an open and fair race where success goes to the swiftest person regardless of his or her social class background. Competitive success is commonly seen as the American alternative to social rank based on family background. Business is therefore viewed as an expression of the idea of equality of opportunity rather than the aristocratic (贵族的) idea of inherited privilege.

单选题Most forest fires are caused by human carelessness, negligence, or ignorance. Forest fire prevention, therefore, is mainly a problem of creating a better understanding of the importance of forests, an awareness of the danger of fire in the woods, and a sense of personal responsibility to safeguard the forests from danger. This is not an easy job. A city dweller, used to paved streets, does not easily change his smoking habits when he goes into the woods. Careless smokers are responsible for thousands of forest fires each year. Many of these are started when cigarette butts and matches are thrown from automobiles. Others are caused by hunters, hikers, fishermen, or woods workers who are careless in disposing of their smoking materials. The Forest Service has posted rules in many of the National Forests that prohibit smoking except in certain designated areas. Many of the states have laws against throwing lighted materials from automobiles. The prevention of smoker-caused fires, however, depends upon changing the attitudes and behavior of millions of people who smoke in hazardous areas. The most important natural cause of fire is lightning. This accounts for 11 percent of forest fires on protected land for the entire nation; in the western States, lightning causes a much higher percentage of fires than it does in the East. Advances in knowledge of fire weather are helping forest protection forces to know when to be alert for lightning-caused fires. Adequate and well-equipped forces can control them quickly and hold the damage to a minimum. Experiments in "seeding" thunder clouds to prevent or control the lightning itself have been in process for many years, but new breakthroughs are needed for any significant reduction in the lightning-caused fires.
