单选题{{B}}TEXT D{{/B}} In the 1920s demand for American farm products fell, as European countries began to recover from World War I and instituted austerity(紧缩) programs to reduce their imports. The result was a sharp drop infarm prices. This period was more disastrous for farmers than earlier times had been, because farmers were no longer self-sufficient. They were paying for machinery, seed, and fertilizer, and they were also buying consumer goods. The prices of the items farmers bought remained constant, while prices they received for their products fell. These developments were made worse by the Great Depression, which began in 1929 and extended throughout the 1930s. In 1929, under President Herbert Hoover, the Federal Farm Board was organized. It established the principle of direct interference with supply and demand, and it represented the first national commitment to provide greater economic stability for farmers. President Hoover's successor attached even more importance to this problem. One of the first measures proposed by President Franklin D. Roosevelt when he took office in 1933 was the Agricultural Adjustment Act, which was subsequently passed by Congress. This law gave the Secretary of Agriculture the power to reduce production through voluntary agreements with farmers who were paid to take their land out of use. A deliberate scarcity of farm productswas planned in an effort to raise prices. This law was declared unconstitutional by the Supreme Court on the grounds that general taxes were being collected to pay one special group of people. However, new laws were passed immediately that achieved the same result of resting soil and providing flood-control measures, but which were based on the principle of soil conservation. The Roosevelt Administration believed that rebuilding the nation's soil was in the national interest and was not simply a plan to help farmers at the expense of other citizens. Later the government guaranteed loans to farmers so that they could buy farm machinery, hybrid (杂交) grain, and fertilizers.

单选题When bringing a newborn baby home from the hospital, most new parents expect a few sleepless nights. However, when an uninterrupted night's sleep becomes a distant memory, and it is no longer weeks, but months or years since you experienced one, a parent may grow angry, frustrated, and exhausted. Our firstborn, Robert, was nine-month-old when a girlfriend mentioned that her month-old daughter was regularly sleeping through the night. I was overcome with bitter envy, for it was a feat our son had yet to do. Finally, at twelve months, he slept an entire night. I was elated, believing we'd finally overcome that particular hurdle. Unfortunately, it was the only complete night's sleep we would enjoy for the next four years. Three pediatricians insisted Robert's problem was not unusual, and that he would eventually grow out of it. He had no problem going to sleep. In fact, at bedtime he never resisted, and drifted off to dreamland with relative ease. Yet, within an hour after my husband and I went to bed, he would wake up. Sometimes those nocturnal activities would include diaper changes, or eventually trips to the bathroom. Yet, often they would be repeated throughout the night, and would require a great deal of coaxing before sleep was again achieved. Sometimes Robert would behave erratically, flailing around restlessly, being cranky and irrational. Had I not personally supervised his daily care, I would have suspected these nightmarish fits were the product of some daytime trauma. As my husband and I desperately sought an uninterrupted night of sleep, we began trying every, trick imaginable. As per advice from the experts, we briefly tried the tough love routine, where a parent checks for the obvious (such as wet diapers), and then walks away, allowing the baby to cry himself to sleep. It was agony for all concerned, and did absolutely no good. Someone suggested that Robert might be waking up, when we all went to bed, due to the absence of noise. My husband immediately purchased a small radio for the nursery. Another article said warm milk before bedtime would do the trick, while another suggested no beverage. We rocked, walked, ignored, coddled, fed, gave beverages, and took them away. The most frightening aspect of this type of problem is what sleep deprivation can eventually do to a parent's state of mind and judgment. I recall one instance when my husband snapped, and began shouting at our wakeful two-year-old son. It so terrified our child, it caused him to literally forget to breathe, and then he broke into a heartbreaking silent sob. My husband was devastated by his own behavior, and we were always grateful that those years of sleepless nights didn't escalate into a more severe situation. By the time Robert was three, we moved to another community, and new doctors. But two doctors later, and a son nearing kindergarten, still had not provided us with a complete night's rest. I wonder about those doctors, who choose to discount our problem, ignoring what it could be doing to our family, and how even the best parents might slip into child abuse when sleep is not sufficient.

单选题{{B}}TEXT C{{/B}} A report consistently brought back by visitors to the 13. S. is how friendly, courteous, and helpful most Americans were to them. To be fair, this observation is also frequently made of Canada and Canadians, and should best be considered North American. There are, of course, exceptions. Smallminded officials, rude waiters, and ill-mannered taxi drivers are hardly unknown in the U. S. Yet it is an observation made so frequently that it deserves comment. For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence. Dullness and loneliness were common problems of the families who generally lived distant from one another. Strangers and travelers were welcome sources of diversion, and brought news of the outside world. The harsh realities of the frontier also shaped this tradition of hospitality. Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the nearest cabin or settlement. It was not a matter of choice for the traveler or merely a charitable impulse on the part of the settlers. It reflected the harshness of daily life: if you didn't take in the stranger and take care of him, there was no one else who would. And someday, remember, you might be in the same situation. Today there are many charitable organizations which specialize in helping the weary traveler. Yet, the old tradition of hospitality to strangers is still very strong in the U. S. , especially in the smaller cities and towns away from the busy tourist trails. "I was just traveling through, got talking with this American, and pretty soon he invited me home for dinner -- amazing." Such observations reported by visitors to the U. S. are not uncommon, but are not always understood properly. Tile casual friendliness of many Americans should be interpreted neither as superficial nor as artificial, but as the result of a historically developed cultural tradition. As is true of any developed society, in America a complex set of cultural signals, assumptions, and conventions underlies all social interrelationships. And, of course, speaking a language does not necessarily mean that someone understands social and cultural patterns. Visitors who fail to "translate" cultural meanings properly often draw wrong conclusions. For example, when an American uses the word "friend", the cultural implications of the word may be quite different from those it has in the visitor's language and culture. It takes more than a brief encounter on a bus to distinguish between courteous convention and individual interest. Yet, being friendly is a virtue that many Americans value highly and expect from both neighbors and strangers.

单选题Denzel Washington and Halle Berry made history Sunday with Academy Award wins, and for many, it was a sweet victory, long past due. Nonetheless, minority groups say diversity must extend beyond Hollywood"s glamour night—and include other groups such as Asians, Hispanics and American Indians. "If this is a sign that Hollywood is finally ready to give opportunity and judge performance based on skill and not on skin color, then it is a good thing," said Kweisi Mfume, president of the National Association for the Advancement of Colored People. "However, if this proves to be a momentary flash in a long history of neglect, then Hollywood has failed to learn the real meaning of equality." In 1939, when Hattie McDaniel became the first African-American actor to win an Oscar for Gone with the Wind, it was a bittersweet victory. McDaniel"s role was blasted by progressive African-American groups, and she was limited for much of the rest of her career in similar, stereotyped roles. Now Washington has won for his part as Alonzo Harris in the violent police thriller Training Day, playing a talented but corrupt narcotics detective who bullies his narcotics squad trainee while ruling the roost in a Los Angeles battle zone. Berry beat the field for her steamy part in Monster"s Ball as Leticia Musgrove, a Southern mother doubly bereaved—by the execution of her husband and the car-accident death of her son. Both movies are frank, verbally profane and violent. They show things unshowable in the time of Gone with the Wind or even 20 or 30 years later. But mostly, they showed that African-Americans could be portrayed onscreen as complex human beings—part good, part bad—rather than the bigot-fodder of decades ago: the cardboard villains, comical personas or long-suffering saints and mammies of Hollywood"s Golden Age. That battle, at least onscreen, was settled long ago. But this year"s double Oscar seals the contract. Nonetheless, some organizations say minorities will have power in front of the camera only when there is more minority representation behind the scenes as directors, writers and producers. "I don"t recall seeing any Asian-Americans, women or men, being recognized and not too many Latin Americans," Washington said, "So there is still a lot of work (to be done)."

单选题 In the whole of French literary history, there is, perhaps, no subject of such inexhaustible and modern interest as that of George Sand. Of what use is literary history? It is not only a kind of museum, in which a few masterpieces are preserved for the pleasure of observers. It is this certainly, but it is still more than this. Fine books are, before anything else, living works, they not only have lived, but they continue to live. They live within us, underneath those ideas which form our conscience and those sentiments which inspire our actions. There is nothing of greater importance for any society than to make an inventory of the ideas and the sentiments which are composing its moral atmosphere every instant that it exists. For every individual this work is the very condition of his dignity. The question is, should we have these ideas and these sentiments, if, in the times before us, there had not been some exceptional individuals, who seized them, as it were, in the air and made them practicable and durable? These exceptional individuals were capable of thinking more vigorously, of feeling more deeply, and of expressing themselves more forcibly than we are. They leaved these ideas and sentiments to us. Literary history is, then, above and beyond all things, the everlasting examination of the conscience of humanity. George Sand wrote for nearly half a century. For fifty times three hundred and sixty-five days, she never let a day pass by without covering more pages than other writers in a month. Her first books shocked people, her early opinions were greeted with storms. From that time forth she rushed head-long into everything new, she welcomed every fantasy and passed it on to us with more force and passion in it. Vibrating with every breath, electrified by every storm, she looked up at every cloud behind which she fancied she saw star shining. The work of another novelist has been called a repertory of human documents. But what a repertory ofideas her work was! She has said what she had to say on nearly every subject: on love, the family, social institutions and on the various forms of government. And with all this she was a woman. Her case is almost unique in the history ofletters. It is intensely interesting to study the influence of this woman of genius on the evolution of modern thought. The share which belongs to George Sand in the history of the French novel is that of having impregnated the novel with the poetry in her own soul. She gave to the novel a breadth and a range which it had never hitherto had. She celebrated the hymn of nature, of love and of goodness in it. She revealed to us the country and the peasants of France. She gave satisfaction to the romantic tendency which is in every one of us, to more or less degree. George Sand's literary ideal may be read in the following words, which she wrote to Flaubert: "You make the people who read your books still sadder than they were before. I want to make them less unhappy." She tried to do this, and she often succeeded in her attempt. What greater praise can we give to her than that? And how can we help adding a little gratitude and affection to our admiration for the woman who was the good fairy of the contemporary novel?
