单选题The aging process may not be the result of a rigid genetic program that in itself dictates longevity. On the contrary, what we see as maximum life span may simply be the complex and indirect result of multiple traits in the organism that are internally tied to normal development. In other words, it is not that the body is somehow pre—programmed to acquire gray hair, wrinkles, or diminished metabolic (新陈代谢的) functions. Rather, these signs of aging are simply telltale side effects of activities of the organism. Consider the analogy of an "aging car". Suppose a distinctive "species" of automobile were designed to burn fuel at a fixed temperature with an efficient rate of combustion (燃烧). That specific rate of combustion is required for appropriate acceleration, cruising speed, fuel mileage (油耗), and so on. But, when the car functions in this way over a period of time, the car also, of necessity, produces certain emission by—products that, over time, begin to clog the cylinders, reduce automotive efficiency, and lead to the breakdown and final collapse of the machine. In the case of the human "car", it could be the burning oxygen in normal metabolism generates harmful by—products in free radicals that prove toxic to the organism. What we see here may be a basic trade—off: oxygen is essential for life yet harmful to our eventual well—being. In this view, the human "car" is not intentionally designed to accumulate toxic emissions in order to collapse. But there seems to be no way for the car to function at optimum levels without the destructive by—products. But suppose we could find some special "fuel additive" that eliminates toxic emissions. Would we then have an "immortal" car? Probably not. Changing the fuel used in your car won"t prevent accidents, nor would any fuel additive prevent rusting or the wearing down of springs and shock absorbers. The human "car" analogy, of course, is misleading, because an organism, unlike a manufactured object, has a capacity for repair and self—generation, at least up to certain point. The whole question about why we grow old is finding out why that capacity for self—repair ultimately seems unable to keep up with the damage rate: in short, why aging and death seem to be universal.

单选题“软实力”概念的提出者美国知名学者约瑟夫·奈深入阐释并推广了国际理论中的另一个新概念——“巧实力”，它是兼具硬实力和软实力优点的一种整体性战略。①实现巧实力，首先，要为国家设立长期的国际定位目标和战略规划。其次，准确列出可用资源目录，涵盖政治、经济、文化等各领域。②第三，评估试图影响目标的资源与偏好，“知己知彼，百战不殆”，清晰地分析行为对象间的差异，③熟悉其所掌握的资源，有助于更好地设定本国外交战略，实现国家意图。第四，在各种权力之间作出重组或选择。无论是硬实力还是软实力，它们的效用应当彼此强化，而不是相互削弱。④第五，评估成功实现目标的可能性，以此来明确自身的国际能力限度，谨慎制定切实可行的外交政策，而不是妄自尊大地作出错误的战略抉择。 上面这段文字缺少这样一句话：“如何权衡它们之间的关系，形成更有效、更灵活的战略方案，将是未来国家的战略重心。”这句话在文中最恰当的位置是______。

单选题Today there are policemen everywhere, but in 1700, London had no policemen at all. A few old men used to protect the city streets at night and they were not paid. About 300 years ago, London was starting to get bigger and more and more people began to live there. The city was very dirty and many people were poor. There were so many thieves who stole money in the streets that people stayed in their homes as much as possible. In 1750, Henry Fielding started to pay a group of people to stop thieves. They were like policemen and were called "Bow Street Runners" because they worked near Bow Street. Fifty years later, there were 120 "Bow Street Runners", but London had become very big and needed more policemen. So in 1829, the first Metropolitan (or London) Police Force was started with 3000 officers. Most of the men worked on foot, but a few rode horses. Until 1920 all the police in London were men. Today, the London police are quite well paid and for the few police officers who still ride horses, the pay is even better than for the others.
