单选题If anyone knew how to get the best medical treatment, it was Betsy Lehman. A health columnist who had worked at the Boston Globe since 1982, she had covered everything from leading-edge research to the finer points of a physician's bedside manner. When she learned she had an advanced case of breast cancer, she carefully studied her options and chose to undergo an experimental treatment offered at the Dana-Farber Cancer Institute, a prestigious hospital affiliated with Harvard Medical School. Tragically, the 39- year-old mother of two died in December. Her death was not the result of her disease but of a huge overdose of a powerful anticancer drug accidentally administered by the hospital's staff. Lehman's case is just one of a spate of medical foul-ups that have made headlines in the U.S. in recent weeks. Though no statistical evidence shows that malpractice is on the rise, state licensing boards have stepped up their investigations of doctors. The number of physicians who have had their licenses revoked, suspended or restricted rose from 1,974 in 1992 to 2,190 in 1993, an 11% increase. Unfortunately, as long as doctors are human, treatment blunders can never be eliminated entirely. "With 4 million patients a day visiting physicians, it's inevitable, if inexcusable, that mistakes will be made," says Dr. James Todd of the American Medical Association. Three large studies over the past 30 years have documented a distressingly consistent rate of medical mishaps in the U.S.. By one measure, such negligence in American hospitals may result in 80,000 deaths each year. That toll is a sign to some critics that improvement is needed in the systems that American hospitals use to catch errors and review doctor's performance. Perhaps the only benefit of highly publicized cases like Betsy Lehman's is that they will spur hospitals to strengthen the safeguards needed to keep such tragedies as uncommon as possible.

单选题Nobody can be really free from the sound. Whether we live in the middle of a modem city or a faraway village, we are surrounded by sound every day such as the sounds from television and radio, household appliances, and traffic. Sound makes up a part of our life. In fact, most of us can not bear total silence. Sound gives us a sense of safety and brings us joy. Scientific tests have also proved that total silence is a very frightening experience for human beings. A recent report shows that people feel quite lonely without background sound while they are working. The background sound which doesn't change too much may even help people to concentrate. However, sometimes, sound is not helpful and joyful in people's life. Normally, we hear these sounds at safe levels that do not affect our hearing. However, when we are exposed to harmful noise--the sounds that are too loud or loud sounds that last a long time, sensitive structures in our inner ear can be damaged, causing hearing loss. Besides, unpleasant sounds, particularly sudden and uneven ones, may cause fear and anger. Noise is a source of stress, which can lead to tiredness, irritability and headaches. Noise can also raise blood pressure, putting strain on the heart. People living in homes exposed to high levels of road-traffic noise were more likely to report having hypertension, according to a study in Environmental Health. The researchers estimate the noise levels for the addresses of more than 24,000 Swedish. They found that people exposed to an average traffic-noise level above 64 decibels ( slightly louder than a normal conversation) were 52 % more likely than people exposed to 45 decibels of road noise to report having high blood pressure, a key risk factor for heart disease, after removing age, socioeconomic status, and other variables. Noise exposure could cause hypertension by persistently elevating the body's level of stress" hormones. Now we know that noise is harmful to our health, but can we get used to the excessive noise? The answer is NO. If, after long exposure to excessive noise, we stop hearing it -- because we have become deaf!

单选题   Hawaii's native minority is demanding a greater degree of sovereignty over its own affairs. But much of the archipelago's political establishment, which includes the White Americans who dominated until the Second World War and people of Japanese, Chinese and Filipino origins, is opposed to the idea. The islands were annexed by the US in 1898 and since then Hawaii's native peoples have fared worse than any of its other ethnic groups. They make up over 60 per cent of the state's homeless, suffer higher levels of unemployment and their life span is five years less than average Hawaiians. They are the only major Hawaiian native group without any degree of autonomy. But a sovereignty advisory committee set up by Hawaii's first native governor, John Waihee, has given the natives' cause a major boost by recommending that the Hawaiian natives decide by themselves whether to re-establish a sovereign Hawaiian nation. However, the Hawaiian natives are not united in their demands. Some just want greater autonomy within the state—as enjoyed by many American Indian natives over matters such as education. This is a position supported by the Office of Hawaiian Affairs (OHA), a state agency set up in 1978 to represent the natives' interests and which has now become the moderate face of the native sovereignty movement. More ambitious is the Ka Lahui group, which declared itself a new nation in 1987 and wants full, official independence from the US. But if Hawaiian natives are given greater autonomy, it is far from clear how many people this will apply to. The state authorities only count as native those people with more than 50 per cent Hawaiian blood. Native demands are not just based on political grievances, though. They also want their claim on 660,000 hectares of Hawaiian crown land to be accepted. It is on this issue that native groups are facing most opposition from the state authorities. In 1933, the state government paid the OHA US $136 million in back rent on the crown land and many officials say that by accepting this payment the agency has given up its claims to legally own the land. The OHA has vigorously disputed this.

单选题In one very long sentence, the introduction to the U. N. Charter expresses the ideals and the common aims of all the people whose governments joined together to form the U. N. "We the people of the U. N. determined to save succeeding generations from the scourge of war which twice in our lifetime has brought untold suffering to mankind, and to reaffirm faith in fundamental rights, in the dignity and worth of the human person, in the equal rights of men and women and of nations, large and small, and to establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can he maintained, and to promote social progress and better standards of life in larger freedom, and for these ends, to practise tolerance and live together in peace with one another as good neighbours, and to unite our strength to maintain international peace and security, and to ensure, by the acceptance of principles and the institution of methods, that armed force shall not be used, save in the common interest, and to employ international machinery for the promotion of economic and social advancement of all peoples, have resolved to combine our efforts to accomplish these aims. " The name "United Nations" is accredited to U.S. President Franklin D. Roosevelt, and the first group of representatives of member states met and signed a declaration of common intent on New Year's Day in 1942. Representatives of five powers worked together to draw up proposals, completed at Dumbarton Oaks in 1944. These proposals, modified after deliberation at the conference on International Organization in San Francisco which began in April 1945, were finally agreed on and signed as the U. N. charter by 50 countries on 26 June 1945. Poland, not represented at the conference, signed the Charter later and was added to the list of original members. It was not until that autumn, however, after the Charter had been ratified by China, France, the U. S. S. R. U. , the U. K. and the U. S. and by a majority of the other participants that the U. N. officially came into existence. The date was 24 October, now universally celebrated as United Nations Day. The essential functions of the U. N. are to maintain international peace and security, to develop friendly relations among nations, to cooperate internationally in solving international economic, social, cultural and human problems, promoting respect for human rights and fundamental freedoms and to be a centre for coordinating the actions of nations on attaining these common ends. No country takes precedence over another in the U. N.. Each member's rights and obligations are the same. All must contribute to the peaceful settlement of international dispute, and members have pledged to refrain from the threat or use of force against other states.

单选题{{B}}Passage 1{{/B}} Parents now have a popular belief that schools are no longer interested in spelling. No school I have taught in has ever ignored spelling or considered it unimportant as a basic skill. There are, however, greatly different ideas about how to teach it or how much priority (优先) it must be given over general language development and writing ability. The problem is that how to encourage a child to express himself freely and confidently in writing without holding him back with the complexities of spelling. If spelling becomes the only focal point of his teacher's interest, clearly a bright child will be likely to "play safe". He will be prone to write only words within his spelling range, choosing to avoid adventurous language. That's why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability. I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible! There are far too many spelling errors and your writing is illegible (难以辨认的). "It may have been a sharp criticism of the pupil's technical abilities in writing, but it was also a sad reflection on the teacher who had omitted to read the essay, which included some beautiful expressions of the child's deep feelings. The teacher was not wrong to draw attention to the errors, but if his priorities had centred on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more motivation (动力) to seek improvement.

单选题Ira Carlin, worldwide media director of the worlds (21) advertising agency, McCann Erickson is quite candid about using fear to sell his message about the communications revolution. One prediction shows that 55 percent of advertising by volume will be carried on the Internet (22) 2005. Consumers will have control and choice of communication; they will also have control over (23) advertisements they watch, and how. "But that will only (24) to the information enabled", says Carlin. "There'll be an upstairs-downstairs schism... The widening (25) between the information enabled and information disenabled is going to be a greater social problem (26) any seeming social problem we've ever had in the past, (27) racial and (28) problems." Look at what is already happening, Carlin says. (29) in Manhattan, he can choose the way he receives his daily news. He can open his front door and pick up his own personal copy of the New York Times. He can (30) the radio station of the New York Times, and listen to the same news. "Or I can simply click into www. newyorktimes. com on the Internet and get the print (31) ; or hear the audio files or see the video (32) the New York Times stringers have supplied, through my computer. It's the same news, but I choose the media modality." The revolution goes (33) . Carlin's computer can currently stream videos to him at 22 frames per second, (34) the picture big enough to occupy one-quarter to one third of the monitor screen. "Six months from now, I guarantee it, I will be able to (35) a full-screen video at 30 frames per second. That means I'll be watching television, but I'll be getting it (36) a telephone connection." McCann Detroit, says Carlin, (37) the world's first video ad, in early 1997, on Pointcast. com is a free news and information service, "fully (38) by advertising". It was (39) in early 1996 and has 2.1 million subscribers in the U.S.. Pointcast. com uses a special software program to work out (40) ads a person might be interested in, by monitoring their selection of news and information on the Net. "I do a lot of technology and marketing work," says Carlin. "Because of that, the computer program thinks I'm rich. It sends me stockbroker ads and technology ads./
