单选题The Aleuts, residing on several islands of the Aleutian Chain, the Pribilof Islands, and the Alaskan peninsula have possessed a written language since 1825, when the Russian missionary Ivan Venation selected appropriate characters of the Cyrillic alphabet to represent Aleut speech sounds, recorded the main body of Aleut vocabulary and formulated grammatical rules. The Czarist Russian conquest of the proud, independent sea hunters was so devastatingly thorough that tribal traditions, even tribal memories, were almost obliterated. The slaughter of the majority of an adult generation was sufficient to destroy the continuity of tribal knowledge, which was dependent upon oral transmission. As a consequence, the Aleuts developed a fanatical devotion to their language as their only cultural heritage. The Russian occupation placed a heavy linguistic burden on the Aleuts. Not only were they compelled to learn Russian to converse with their overseers and governors, but they had to learn Old Slavonic to take an active part in church services as well as to master the skill of reading and writing their own tongue. In 1867, when the United States purchased Alaska, the Aleuts were unable to break sharply with their immediate past and substitute English for any one of their three languages. To communicants of the Russian Orthodox Church a knowledge of Slavonic remained vital as did Russian, the language in which one conversed with the clergy. The Aleuts came to regard English education as a device to wean them from their religious faith. The introduction of compulsory English schooling caused a minor renascence of Russian culture as the Aleut parents sought to counteract the influence of the schoolroom. The harsh life of the Russian colonial rule began to appear more happy and beautiful in retrospect. Regulations forbidding instruction in any language other than English increased its unpopularity. The superficial alphabetical resemblance of Russian and Aleut linked the two tongues so closely that every restriction against teaching Russian was interpreted as an attempt to eradicate the Aleut tongue. From the wording of many regulations, it appears that American administrators often had not the slightest idea that the Aleuts were clandestinely reading and writing their own tongue or even had a written language of their own. To too many officials, anything in Cyrillic letters was Russian and something to be stamped out. Bitterness bred by abuses and the exploitations the Aleuts suffered from predatory American traders and adventurers kept alive the Aleut resentment against the language spoken by Americans. Gradually despite the failure to emancipate the Aleuts from a sterile past by relating the Aleut and English languages more closely, the passage of years has assuaged the bitter misunderstandings and caused an orientation, away from Russian toward English as their second language, but Aleut continues to be the language that molds their thought and expression.

单选题In bringing up children, every parent watches eagerly the child's acquisition (学会) of each new skill--the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practise what they preach (说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.

单选题In the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all the people in the U.S. equal. Some of them de tided to "drop out" of American society and form their own societies. They formed utopian communities, which they called "communes", where they could follow their philosophy of "do your own thing". A group of artists founded a commune in southern Colorado called "Drop City". Following the ideas of philosopher and architect Buckminster Fuller, they built dome- shaped house from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers of San Francisco poet Steve Gaskin, and a group that called itself the Hog Farm, lived in old school buses and travelled around the United States. The Hog Farm became famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin's followers tried to settle down on a farm in Tenessee, but they had to leave when some members of the group were arrested for growing marijuana. Not all communes believed in the philosophy of "do your own thing" however; Twin Oaks, a commune founded in Virginia in the late 1960s, was based on the ideas of psychologist B. F. Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972,Italian architect Paolo Soleri began to build Arcosanti, a utopian city in Arizona where 2,500 people will live closely together in one large building called an "archaeology". Soleri believes that people must live closely together so that they will all become one.

单选题Most people who develop Lyme disease, a tick-borne infection that's endemic in parts of the Northeast and Midwest, are easily cured by taking an antibiotic like doxycycline for a couple of weeks. But for years a debate has raged over what to do about patients whose symptoms (fatigue, mental confusion, joint pain) never seem to clear up. One small but vocal group of doctors and patient advocates believes that Lyme's corkscrew-shaped spirochetes have tunneled deep into their victims' bodies and can be eradicated only with intensive antibiotic treatment over many months. Another group believes, just as adamantly, that the bacteria are long gone, making further treatment with powerful antibiotics—which can lead to potentially fatal infections or blood clots—positively dangerous. Now comes word of two studies in the New England Journal of Medicine that show that long-term antibiotic treatment is no better than a placebo for folks with chronic Lyme disease. Originally scheduled for publication in July, the research is part of a group of findings made public last week -just in time for the peak Lyme months of June and July. If confirmed by another major study that's looking at chronic Lyme and antibiotics from a slightly different perspective, the results would seem to settle the question once and for all. Researchers from Boston, New Haven, Conn., and Valhalla, N. Y., followed 129 patients who had previously been treated for well-documented eases of Lyme disease. Sixty-four were given antibiotics directly into their veins for a month, followed by two months of oral antibiotics. The others received dummy medications. A third of the chronic Lyme patients got better while taking the antibiotics. But so did a third of those on the placebo. Indeed, the results were so similar that a monitoring board decided to cut the trials short rather than add more subjects to the test groups. Unfortunately, the debate over chronic Lyme has become so heated that no one expects the controversy to go away. But both sides may take comfort in the other findings that were released by the New England Journal last week. After studying 482 subjects bitten by deer ticks in a part of New York with a lot of Lyme disease, researchers concluded that a singly 200-rug dose of doxycycline dramatically cut the risk of contracting the disease. That good news is tempered somewhat by the fact that 80% of patients who develop the infection don't remember ever being bitten by a tick. (The bugs inject an anesthetic into the skin to mask the pain and in their nymph stage are so small—about the size of a poppy seed--that they are easily overlooked.) There's still plenty you can do to protect yourself in a Lyme-infested neighborhood: tuck your pants in your socks, spray DEET on your clothing, check yourself and your kids for ticks. And if you develop a spreading red rash—particularly if it's accompanied by joint pain, chills or confusion—make sure you see a doctor right away. The tick, as always, is to be vigilant without overreacting.
