问答题I have always disliked being a man. 1. The whole idea of manhood in America is pitiful, in my opinion. Even the expression "Be a man!" strikes me as insulting and abusive. It means: Be stupid, be unfeeling, obedient, soldierly and stop thinking. Man means "manly" -- how can one think about men without considering the terrible ambition of manliness? And yet it is part of every man"s life. It is a hideous and crippling lie; it not only insists on difference and connives at superiority, it is also by its very nature destructive -- emotionally damaging and socially harmful. In is very hard to imagine any concept of manliness that does not belittle women, and it begins very early. At an age when I wanted to meet girls -- let"s say the treacherous years of thirteen to sixteen -- I was told to take up a sport, get more fresh air, and I was urged not to read so much, If you asked too many questions about sex you were sent to camp -- a boy"s camp, of course: the nightmare. Nothing is more unnatural or prison-like than a boy"s camp. 2. It ought to be clear by now that I have something of an obiection to the way we turn boys into men. It does not surprise me that when the President of the United States has his customary weekend off he dresses like a cowboy-it is both a measure of his insecurity and his willingness to please. In many ways, American culture does little more for a man than prepare him for modeling clothes in the L.L. Bean catalogue. There was a fear that writing was not a manly profession -- indeed, not a profession at all. The paradox in American letters is that it has always been easier for a woman to write and for a man to be published. 3. Writing is only manly when it produces wealth -- money is masculinity. So is drinking, particularly the ability to drink another man under the table. A man in America has to kill lions, hunt ducks, and carry_ enough knives and ~uns on his shoulders, to prove that he is just as much monster as the next man. Everything in stereotyped manliness goes against the life of the mind. 4. There would be no point in saying any of this if it were not generally accepted that to be a man is somehow -- even now in feminist-influenced America -- a privilege. It is on the contrary an unmerciful and punishing burden. Being a man is bad enough; being manly is appalling. It is the sinister silliness of man"s fashions, and a clubby attitude in the arts. It is the subversion of good students. It is the so-called "Dress Code" of the Ritz-Carlton Hotel in Boston, and it is the institutionalized cheating in college sports. In is the most primitive insecurity.

问答题Without doubt, the international relations appear at times bewildering. Students may at time feel that their efforts to understand the complexities of the international system today are futile. The task is a difficult one, but it is not futile. It requires patience and persistence as well as logical inquiry and flexible perspectives. 71. As the examples just given often illustrate, contemporary international events are regularly interrelated; our task of achieving understanding is therefore further Complicated because seemingly unrelated events in different areas of the world may over a period of time combine to affect still other regions of the globe. Events are demonstrably interdependent, and as we improve our ability to understand the causes of and reasons behind this interdependence, we will improve our ability to understand contemporary international relations. How can our task best be approached? Throughout history, analysts of international relations have differed in their approaches to improving understanding in their field. During the late 19th and early 20th centuries, for example, the study of international relations centered around diplomatic history. Who did what to whom at a particular time and place were the main features of the method of diplomatic history. This methodology concentrated on nation-states as the main actors in international relations and included the study of the major diplomats and ministers of the period. Detailed accuracy was required and obtained, but seldom were causal connections or comprehensive analyses sought. 72. As a means for understanding a particular series of events, diplomatic history was(and is)excellent; as a means for understanding a particular sweeps of international relations or for developing a theoretical basis for the study of international relations, diplomatic history was(and is) of limited utility. Whereas diplomatic history sought to explain a particular series of events, other methodologies were developed during the 19th and early 20th centuries that viewed international relations on a global scale. 73. Strategic and geopolitical analyses, methodologies in wide use even today, trace their roots to concepts developed by the U. S. Admiral Alfred Mahan during the late 19th century and British geographer Sir Halford Mackinder during the early 20th century.To Mahan the world's ocean were its high-ways, and whoever controlled its highways could control the course of international relations. Mahan bases most of his analysis on Great Britain and its Royal Navy. Partly because of the urgings of Mahan, the United States on Great Britain and its fleet during the late 19th century and actively sought and acquired territorial possessions in the Pacific Ocean, including Hawaii, Samoa Guam and the Philippines.

问答题 Exactly where we will stand in the long war against disease by the year 2050 is impossible to say. (46){{U}} But if developments in research maintain their current pace, it seems likely that a combination of improved attention to dietary and environmental factors, along with advances in gene therapy and protein targeted drugs, will have virtually eliminated most major classes of disease{{/U}}. From an economic standpoint, the best news may be that these accomplishments .could be accompanied by a drop in health-care costs.

问答题我反复尝试，终于得到了一份工作。

问答题At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is least. 71. Earlier, we were infants and young children, and consequently more vulnerable; later, we shall undergo a progressive loss of our vigor and resistance which, though imperceptible at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigor with the passing of time is called aging. It is one the most unpleasant discoveries which we make that we must decline in this way, that if we escape wars, accidents and diseases we shall eventually "die of old age", and that this happens at a rate which differs little from person to person, so that there are heavy odds in favor of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and robust we are. Normal people tend to forget this process unless and until they are reminded of it. 72. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigor with time, of becoming more likely to die the older we get was something self-evident, like the cooling of a kettle of hot water or the wearing-out of a pair of shoes. They are also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things "wear out". Most animals we commonly observe do in fact age as we do if given the chances to live long enough; and mechanical systems like a wound watch, or the sun, do in fact run out of energy in accordance with the second law of thermodynamics. But these are not analogous to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself—it does not consist of living parts, only of metal, which wears away by friction. 73. We could, at one time, repair ourselves—well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose the power; an illness which at twelve would knock us over, at eighty years can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again.

问答题Telling stories is as basic to human beings as eating. More so, in fact, for while food makes us live, stories are what make our lives worth living. They are what make our condition human. This was recognized from the very beginnings of western civilization. Hesiod tells us how the founding myths were invented to explain how the world came to be and how we came to be in it. Myths were stories people told themselves in order to explain themselves to themselves and to others. But it was Aristotle who first developed this insight into a philosophical position when he argued, in his Poetics, that the art of storytelling—defined as the dramatic imitating and plotting of human action—is what gives us a shareable world. It is, in short, only when haphazard happenings are transformed into story, and thus made memorable over time, that we become full agents of our history.

问答题Researchers investigating brain size and mental ability say their work offers evidence that education protects the mind from the brain"s physical deterioration. 1 It is known that the brain shrinks as the body ages, but the effects on mental ability are different from person to person. Interestingly, in a study of elderly men and women, those who had more education actually had more brain shrinkage. "That may seem like bad news," said study author Dr. Edward Coffey, a professor of psychiatry and of neurology at Henry Ford Health System in Detroit. 2 However, he explained, the finding suggests that education allows people to withstand more brain tissue loss before their mental functioning begins to break down. The study, published in the July issue of Neurology, is the first to provide biological evidence to support a concept called the "reserve" hypothesis, according to the researchers. In recent years, investigators have developed the idea that people who are more educated have greater cognitive reserves to draw upon as the brain ages; in essence, they have more brain tissue to spare. 3 Examining brain scans of 320 healthy men and women aged 66 to 90, researchers found that for each year of education the subjects had, there was greater shrink age of the outer layer of the brain known as the cortex. Yet on tests of cognition and memory, all participants scored in the range indicating normal. "Everyone has some degree of brain shrinkage," Coffey said. "People lose (on average) 2.5 percent per decade starting in adulthood." There is, however, a "remarkable range" of shrinkage among people who show no signs of mental decline, Coffey noted. Overall health, he said, accounts for some differences in brain size. Alcohol or drug use, as well as medical conditions such as diabetes and high blood pressure, contribute to brain tissue loss throughout adulthood. In the absence of such medical conditions, Coffey said, education level helps explain the range of brain shrinkage exhibited among the mentally-fit elderly. The more-educated can withstand greater loss. 4 Coffeyand colleagues gauged shrinkage of the cortex by measuring the cerebrospinal fluid (脑脊液) surrounding the brain. The greater the amount of fluid, the greater the cortical (脑皮层的) shrinkage. Controlling for the health factors that contribute to brain injury, the researchers found that education was related to the severity of brain shrinkage. For each year of education from first grade on, subjects had an average of 1.77 milliliters 11 more cerebrospinal fluid around the brain. Just how education might affect brain cells is unknown. 5 In their report, the researchers speculated that in people with more education, certain brain structures deeper than the cortex may stay intact to compensate for cortical shrinkage.
