The working group that drew up the report, however, has expressed some concern about the treatment of children and difficulties faced by some patients in arranging their own transport to travel to emergency centers. Improvements are being sought by the Scottish Office on these issues to improve the quality, fairness, and responsiveness of the system. The inquiry was prompted by the deaths of two babies in Ayrshire after the local cooperative, Ayrshire Doctors on Call, provided telephone advice but declined requests for home visits. Parents of the dead children criticized the cooperative for failing to send out a doctor. The parents supported a campaign that called for automatic home visits to be provided for certain groups of patients, such as children and elderly people. That idea has been rejected by the inquiry team, which said that neither patient nor professional groups accepted the value of policies that would provide automatic home visits. Instead, it is recommended that cooperatives carry out more effective monitoring of treatment for children, including reviewing complaints and critical incidents. The first GP cooperatives were formed three years ago to take over out of hours calls from individual practices, but they were established with different working practices. The report notes that variation exists in transport arrangements, with some cooperatives providing free transport to emergency centers and others requiring people often make their own arrangements. Health board have been ordered to report on the fairness of transport arrangements in their area. Guidelines are also to be introduced to ensure that cooperatives are working to similar high standards. They will include arrangements that will allow patients to make contact with an out of hours service with a single phone call. Initiatives are also planned to help GPs in rural areas who have been unable to benefit from the development of cooperatives. An extra 540 000 is being provided to pay for these developments.

单选题Life Expectancy in the Last Hundred Years A hundred years ago, life expectancy in developed countries was about 47 in the early 21st century, men in the United States and the United Kingdom can expect to live to about 74. Women to about 80, and these (51) are rising all the time. What has brought (52) these changes? When we look at the life (53) of people 100 years ago, we need to look at the greatest (54) of the time. In the early 20th century, these were the acute and often (55) infectious diseases such as smallpox. Many children died Very young from these diseases and others, and the weak and elderly were always at risk. In the (56) world these diseases are far (57) today, and in some cases have almost disappeared. A number of (58) have led to this: improvements in sanitation and hygiene, the discovery and use of antibiotics, which (59) bacterial diseases much less dangerous, and vaccinations (60) common diseases. (61) , people's general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better and warmer housing, and better understanding of nutrition. Genetically, we should all be able to live to about 85 but (62) people do live longer today, there are still some big killers around that are preventing US from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those (63) by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect (64) people, but there are worrying trends in the developed world with problems such as obesity (65) more heart disease and illnesses such as diabetes at younger ages. The killers today can be classed as "lifestyle diseases", which means that it may be possible to halt their progress.

Babies that weigh less than two and one-half kilograms at birth have a greater risk of dying. Those that survive are more likely to experience problems with their development. And experts say that as adults they have a higher risk of diseases including heart disease and diabetes. The World Health Organization estimates that every year twenty million babies are born with low birth weight. Nine out of ten of them are born in developing countries. The new study took place in Dar es Salaam. 4,200 pregnant women received multivitamins. The pills contained all of the vitamins in the B group along with vitamins C and E. They also contained several times more iron and folate than the levels advised for women in developed nations. Pregnant women especially in poor countries may find it difficult to get enough vitamins and minerals from the foods in their diet. The scientists compared the findings with results from a group of 4,000 women who did not receive the vitamins. A report by the scientists, from the United States and Tanzania, appeared in the New England Journal of Medicine. Wafaie Fawzi of the Harvard University School of Public Health4 led the study. None of the women in the study had HIV, the virus that causes AIDS. The scientists reported earlier that daily multivitamins were a low-cost way to reduce fetal deaths in pregnant women infected with5 HIV. The earlier work in Tanzania also found improvement in the mothers in their number of blood cells known as lymphocytes. Lymphocytes increase the body's immunity against infection. The new study in pregnant women who were not infected with the AIDS virus found that multivitamins reduced the risk of low birth weight. Just under eight percent of the babies born to women who took the multivitamins weighed less than 2,500 grams. The rate was almost nine and one-half percent in the group of women who received a placebo, an inactive pill, instead of the vitamins. But the vitamins did not do much to reduce the rates of babies being born too early or dying while still a fetus. Still, the researchers say multivitamins should be considered for all pregnant women in developing countries.

单选题A Biological Clock Every living thing has what scientists call a biological clock that controls behavior. The biological clock tells 1 when to form flowers and when the flowers should open. It tells 2 when to leave the protective cocoons and fly away, and it tells animals and human beings when to eat, sleep and wake. Events outside the plant and animal 3 the actions of some biological clocks. Scientists recently found, for example, that a tiny animal changes the color of its fur 4 the number of hours of daylight. In the short 5 of winter, its fur becomes white. The fur becomes gray brown in color in the longer hours of daylight in summer. Inner signals control other biological clocks. German scientists found that some kind of internal clock seems to order birds to begin their long migration 6 twice each year. Birds 7 flying become restless when it is time for the trip, 8 they become calm again when the time of the flight has ended. Scientists say they are beginning to learn which 9 of the brain contain biological clocks. An American researcher, Martin Moorhead, said a small group of cells near the front of the brain 10 to control the timing of some of our actions. These 11 tell a person when to 12 , when to sleep and when to seek food. Scientists say there probably are other biological clock cells that control other body activities. Dr. Moorhead is studying 13 our biological clocks affect the way we do our work. For example, most of us have great difficulty if we must often change to different work hours. 14 can take many days for a human body to accept the major change in work hours. Dr. Moorhead said industrial officials should have a better understanding of biological clocks and how they affect workers. He said 15 understanding could cut sickness and accidents at work and would help increase a factory"s production.

单选题Bringing Nanotechnology to Health Care for the Poor Nanotechnotogy uses matter at the level of molecules and atoms. Researchers are finding different uses for particles with a length of one nanometer, or one-billionth of a meter. These include things like beauty products and dirt-resistant clothing. But one area where many experts believe nanotechnology holds great promise is medicine. Last week, speakers at a program in Washington discussed using nanotechnology to improve health care in developing countries. The program took place at the Woodrow Wilson International Center for Scholars. Peter Singer at the University of Toronto says a nanotechnology called quantum dots could be used to confirm cases of malaria. He says it could offer a better way than the traditional process of looking at a person"s blood under a microscope. In poor countries, this process is often not followed. As a result, sick people may get treated for malaria even if they do not have it. Such misuse of medicines can lead to drug resistance. Quantum dots are particles that give off light when activated. Researchers are studying ways to program them to identify diseases by lighting up in the presence of a targeted molecule. Experts say nanotechnology shows promise not just for diagnosing diseases, but also for treating them. Piotr Grodzinski, Professor of the National Institutes of Health, talked about how nanotechnology could make drugs more effective. He talked about cancer drugs already developed with nanotechnology. He says if a drug can target a cancer locally in the body, then much less of it might be needed, and that means lower side effects. Andrew Maynard is chief scientist for the Project on Emerging Nanotechnologies at the Woodrow Wilson Center. He noted that Brazil, India, China and South Africa are currently doing nanotechnology research that could help poor countries. But he also noted that there is some risk in using nano-materials. He says nanometer-sized particles behave differently in the body and the environment compared to larger particles. Experts say more investment in research is needed to better understand these risks.

When you consider the fact that the money is supposed to be given to. Children in need of medical care, you might call the idea crazy. Most student leaders don't want to spend a large amount of time on something they care little a bout, said 22-year-old University of Florida student Darren Heitner. He was the Dance Marathon's operations officer for two years. Yvonne Fangmeyer, director of the student organization office at the University of Wisconsin, conducted a survey in February of students involved in campus organizations. She said the desire for friendship was the most frequently cited reason for joining. At large universities like Fangmeyer's, which has more than 40,000 students, the students first of all want to find a way to "belong in their own comer of campus". Katie Rowley, a Wisconsin senior, confirms the survey's findings. "I wanted to make the cam pus feel smaller by joining an organization where I could not only get involved on campus but also find a group of friends. " All of this talk of friendship, however, does not mean that students aren't thinking about their resumes. "I think that a lot of people do join to ' fatten up their resume' ," said Heitner. "At the beginning of my college career, I joined a few of these organizations, hoping to get a start in my leadership roles. " But without passion student leaders can have a difficult time trying to weather the storms that come. For example, in April, several student organizations at Wisconsin teamed up for an event de signed to educate students about homelessness and poverty. Student leaders had to face the problem of solving disagreements, moving the event because of rainy weather, and dealing with the university's complicated bureaucracy. "Outside-of the classroom learning really makes a big difference. " Fangmeyer said.

单选题I'm Sorry, I Won't Apologize Almost daily, news reports include accounts of public figures or heads of companies being forced to say they're sorry. In a recent case, Marge Schott, managing partner of the Cincinnati Reds, at first did not want to apologize for her remark that Hitler "was good at the beginning but he just went too far. "Under pressure, she finally said that she regretted her remarks "offended many people. "Predictably-and especially given her history with such comments-many were not satisfied with this response and successfully lobbied for her resignation. This particular use of "I'm sorry" has a familiar ring. The other day my husband said to me, "I'm sorry I hurt your feelings. "I knew he was really trying. He has learned, through our years together, that apologies are important to me. But he was grinning, because he also knew that "I'm sorry I hurt your feelings" left open the possibility-indeed, strongly suggested-that he regretted not what he did but my emotional reaction. It sometimes seems that he thinks the earth will open up and swallow him if he admits fault. It may appear that insisting someone admit fault is like wanting him to humiliate himself. But I don't see it that way, since it's no big deal for me to say I made a mistake and apologize. The problem is that it becomes a big deal when be won't. This turns out to be similar to the Japanese view. Following a fender bender, according to a Times article, the Japanese typically get out of their cars and bow, each claiming responsibility. In contrast, Americans are instructed by their insurance companies to avoid admitting fault. When an American living in Japan did just that-even though he knew he was to blame-the Japanese driver "was so incensed by the American's failure to show contrition that be took the highly unusual step of suing him. " The Japanese driver and I are not the only ones who are offended when someone obviously at fault doesn't just less up and apologize. A woman who lives in the country told me of a similar reaction. One day she gave her husband something to mail when he went into town. The next day, when they left the house together, she found her unmailed letter in the car. He said, "Oh, I forgot to mail your letter. "She was furious-not because he had forgotten, but because be didn't apologize.
