单选题Today is the anniversary of that afternoon in April a year ago that I first saw the strange and appealing doll in the window of Abe Sheftel"s toy shop on Third Avenue near Fifteenth Street, just around the comer from my office, where the plate on the door reads: Dr. Samuel Amory. I remember just how it was that day: the first hint of spring floated across the East River, mixing with the soft-coal smoke from the factories and the street smells of the poor neighborhood. As I turned the comer on my way to work and came to Sheftel"s, I was made once more aware of the poor collection of toys in the dusty window, and I remembered the approaching birthday of a small niece of mine in Cleveland, to whom I was in the habit of sending modest gifts. Therefore, I stopped and examined the window to see if there might be anything suitable, and looked at the confusing collection of unappealing objects—a red toy fire engine, some lead soldiers, cheap baseballs, bottles of ink, pens, yellowed envelopes, and advertisements for soft drinks. And thus it was that my eyes eventually came to rest upon the doll stored away in one corner, a doll with the strangest, most charming expression on her face. I could not wholly make her out, due to the shadows and the film of dust through which I was looking, but I was aware that a tremendous impression had been made upon me as though I had run into a person, as one does sometimes with a stranger, with whose personality one is deeply impressed.

单选题During the cold war the world was divided into the First, Second and Third Worlds. Those divisions are no longer relevant. It is far more meaningful now to group countries not in terms of their political or economic systems or in terms of their level of economic development but rather in terms of their culture and civilization. What do we mean when we talk of a civilization? A civilization is a cultural entity. Villages, regions, ethnic groups, nationalities, religious groups, all have distinct cultures at different levels of cultural heterogeneity. The culture of a village in southern Italy may be different from that of a village in northern Italy, but both will share in a common Italian culture that distinguishes them from German villages. European communities, in turn, will share cultural features that distinguish them from Arab or Chinese communities. Arabs, Chinese and Westerners, however, are not part of any broader cultural entity. They constitutes civilization. A civilization is thus the highest cultural grouping of people and the broadest level of cultural identity people have short of that which distinguishes humans from other species. It is defined both by common objective elements, such as language, history, religion, customs, institutions, and by the subjective self-identification of people. People have levels of identity: a resident of Rome may define himself with varying degrees of intensity as a Roman, an Italian, a Catholic, a European, or a Westerner. The civilization to which he belongs is the broadest level of identification with which he intensely identifies. People can and do redefine their identities and, as a result, the composition and boundaries of civilizations change. Civilizations may involve a large number of people, as with China ("a civilization pretending to be a state, as Lucian Pye put it"), or a very small number of people, such as the Anglophone Caribbean. A civilization may include several nation states, as is the case with Western, Latin American and Arab civilizations, or only one, as is the case with Japanese civilization. Civilizations obviously blend and overlap, and may include subcivilizations. Western civilization has two major variants, European and North American, and Islam has its Arab, Turkic and Malay subdivisions. Civilizations are nonetheless meaningful entities, and while the lines between them are seldom sharp, they are real. Civilizations are dynamic; they rise and fall; they divide and merge. And, as any student of history knows, civilizations disappear and are buried in the sands of time. Westerners tend to think of nation states as the principle actors in global affairs. They have been that, however, for only a few centuries. The broader reaches of human history have been the history of civilizations. In A Study of History, Arnold Toynbee identified 21 major civilizations; only six of them exist in the contemporary world. Civilization identity will be increasingly important in the future, and the world will be shaped in large measure by the interactions among seven or eight major civilizations. These include Western, Confucian, Japanese, Islamic, Hindu, Slavic-Orthodox, Latin American and possibly African civilization. The most important conflicts of the future will occur along the cultural fault lines separating these civilizations from one another.

单选题"The highest merit we ascribe to Moses, Plato, and Milton," says Emerson, "is that they set at nought books and traditions, and spoke not what men thought but what they thought. A man should learn to detect and watch that gleam of light which flashes across his mind from within, more than the luster of the firmament of bards and sages. Yet he dismisses without notice his thought because it is his. In every work of genius we recognize our own rejected thoughts; they come back to us with a certain alienated majesty." It is strange that any one who has recognized the individuality of all works of lasting influence should not also recognize the fact that his own individuality ought to be steadfastly preserved. As Emerson says in continuation, "Great works of art have no more affecting lesson for us than this. They teach us to abide by our spontaneous impressions with good- humored inflexibility, then most when the whole cry of voices is on the other side. Else tomorrow a stranger will say with masterful good sense precisely what we have thought and felt all the time, and we shall be forced to take with shame our opinion from another." Accepting the opinions of another and the tastes of another is very different from agreement in opinion and taste. Originality is independence, not rebellion. It is sincerity, not antagonism. Whatever you believe to be true and false, that proclaim to be true and false. Whatever you think admirable and beautiful, that should be your model, even if ail your friends and ail the critics storm at you as a crotchet-monger and an eccentric. Whether the public will feel its truth and beauty at once, or after long years, or never cease to regard it as paradox and ugliness, no man can foresee. Enough for you to know that you have done your best, have been true to yourself, and that the utmost power inherent in your work has been displayed.

单选题While still catching-up to men in some spheres of modern life, women appear to be way ahead in at least one undesirable category. "Women are particularly susceptible to developing depression and anxiety disorders in response to stress compared to men," according to Dr. Yehuda, chief psychiatrist at New York's Veteran's Administration Hospital. Studies of both animals and humans have shown that sex hormones somehow affect the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions. In several of the studies, when stressed-out female rats had their ovaries(the female reproductive organs)removed, their chemical responses became equal to those of the males. Adding to a woman's increased dose of stress chemicals, are her increased "opportunities" for stress. "It's not necessarily that women don't cope as well. It's just that they have so much more to cope with," says Dr. Yehuda. " Their capacity for tolerating stress may even be greater than men's," she observes, "it's just that they're dealing with so many more things that they become worn out from it more visibly and sooner. " Dr. Yehuda notes another difference between the sexes. " I think that the kinds of things that women are exposed to tend to be in more of a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed to more acts of random physical violence. The kinds of interpersonal violence that women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family members, and they tend not to be one-shot deals. The wear-and-tear that comes from these longer relationships can be quite devastating. " Adeline Alvarez married at 18 and gave birth to a son, but was determined to finish college. "I struggled a lot to get the college degree. I was living in so much frustration that was my escape, to go to school, and get ahead and do better. " Later, her marriage ended and she became a single mother. "It's the hardest thing to take care of a teenager, have a job, pay the rent, pay the car payment, and pay the debt. I lived from paycheck to paycheck. "
