单选题Shortly after September 11th, President Bush's father observed that just as Pearl Harbor awakened this country from the notion that we could somehow avoid the call of duty to defend freedom in Europe and Asia in World War Two, so, too, should this most recent surprise attack erase the concept in some quarters that America can somehow go it alone in the fight against terrorism or in anything else for that matter. But America's allies have begun to wonder whether that is the lesson that has been learned--or whether the Afghanistan campaign's apparent success shows that unilateralism works just fine. The United States, that argument goes, is so dominant that it can largely afford to go it alone. It is true that no nation since Rome has loomed so large above the others, but even Rome eventually collapsed. Only a decade ago, the conventional wisdom lamented an America in decline. Bestseller lists featured books that described America's fall. Japan would soon become "Number One". That view was wrong at the time, and when I wrote "Bound to Lead" in 1989, I, like others, predicted the continuing rise of American power. But the new conventional wisdom that America is invincible is equally dangerous if it leads to a foreign policy that combines unilateralism, arrogance and parochialism. A number of advocates of "realist" international-relations theory have also expressed concern about America's staying-power. Throughout history, coalitions of countries have arisen to balance dominant powers, and the search for traditional shifts in the balance of power and new state challengers is well under way. Some see China as the new enemy; others envisage a Russia-China-India coalition as the threat. But even if China maintains high growth rates of 6% while the United States achieves only 2%, it will not equal the United States in income per head until the last half of the century. Still others see a uniting Europe as a potential federation that will challenge the United States for primacy. But this forecast depends on a high degree of European political unity, and a low state of transatlantic relations. Although realists raise an important point about the leveling of power in the international arena, their quest for new cold-war-style challengers is largely barking up the wrong tree. They are ignoring deeper changes in the distribution and nature of power in the contemporary world. The paradox of American power in the 21st century is that the largest power since Rome cannot achieve its objectives unilaterally in a global information age.

问答题(46) For centuries the smoking of tobacco in cigarettes, cigars, and pipes has produced controversy over possible health hazards, but only since the 1950's has sufficient scientific evidence accumulated to make possible a thorough evaluation of the health risk. Scientific investigation of the relationship of smoking and health gained impetus after the beginning of the 20th century, then an increase in lung cancer was noted. As the use of tobacco increased, studies improved. (47) Although some gaps in knowledge still exist, the information now available is sufficient to permit making sound judgments, based on the converging lines of evidence. (48) Investigators have directed their principal consideration to cigarette smoking because the health consequences attributed to it far exceed those due to smoking cigars and pipes. The widespread popularity of cigarettes is comparatively recent in man's use of tobacco. The smoking pattern began to change at the beginning of the 20th century. Since then, cigarettes have steadily become more popular than cigars and pipes. (49) In the United States. per capita cigarette consumption — calculated for all persons 15 years of age and older, regardless of whether they smoked—rose from 49 per year in 1900 to 3,888 in 1960. Per capita consumption of cigars, pipe tobacco, and chewing tobacco declined sharply in the same period. Data presented in 1966 indicated a sharp reduction in cigarette smoking in the United States for men under the age of 55 with the trend continuing to 1970. Further increase in cigarette consumption for women of all ages was reported in 1966 and no further increase was noted 1966 and 1970. However, in 1970 overall per capita cigarette consumption rose. By 1962 the Royal College of Physicians of London reported:" Cigarette smoking is a cause of lung cancer and bronchitis, and various other less common diseases. It delays healing of gastric and duodenal ulcers." Some scientists, however, expressed dissenting opinions. The most widely publicized report in the United States was issued in 1964 by the Surgeon General's Advisory Committee on Smoking and Health. (50) The principal judgment in the committee's 150,000-word report was: "Cigarette smoking is a health hazard of sufficient importance in the United States to warrant appropriate remedial action." The smokers of pipes and cigars were found to incur less health risk. However, the incidence of cancer and heart disease among them was found to be greater than among nonsmokers.
