单选题Migrant Workers In the past twenty years, there has been an increasing tendency for workers to move from one country to another. (51) some newly independent countries have understandably restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, (52) increased oil incomes have enabled many countries to (53) outsiders to improve local facilities. (54) the Middle East has attracted oil-workers from the USA and Europe. It has brought in construction workers and technicians from many countries, (55) South Korea and Japan. In view of the difficult living and working conditions in the Middle East, it is not (56) that the pay is high to attract suitable workers. Many engineers and technicians can earn at least (57) money in the Middle East as they can in their own country, and this is a major attraction. An allied benefit is the low taxation or complete lack of it. This increases the net amount of pay received by visiting workers and is very popular with them. Sometimes a disadvantage has a compensating advantage. (58) , the difficult living conditions often lead to increased friendship when workers have to depend on each other (59) safety and comfort. (60) , many migrant workers can save large sums of money partly (61) the lack of entertainment facilities. The work is often complex and full of problems but this merely presents greater challenge to engineers who prefer to find solutions (62) problems rather than do routine work in their home country. One major problem which (63) migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. (64) , migrant workers accept this disadvantage, along with others, because of the (65) financial benefits which they receive.

单选题 Eating Potatoes Gives Your Immune System a Boost Eating potatoes is not only good for bowel health, but also for the whole immune system, especially when they come in the form of a potato salad or eaten cold. In a study on an animal model, researchers in Spain found that pigs fed large {{U}} {{U}} 1 {{/U}} {{/U}}of raw potato starch (RPS) not only had a healthier bowel, but also decreased levels of white blood cells, {{U}} {{U}} 2 {{/U}} {{/U}}as leucocytes and lymphocytes in their blood. White blood cells are produced as a {{U}} {{U}} 3 {{/U}} {{/U}}of inflammation or disease, generally when the body is challenged. The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect, a generally more {{U}} {{U}} 4 {{/U}} {{/U}}body. The reduction in leucocyte levels was about 15 percent. Lower lymphocyte levels are also indicative of {{U}} {{U}} 5 {{/U}} {{/U}}levels of inflammation, but the observed reduction in both lymphocyte density {{U}} {{U}} 6 {{/U}} {{/U}}lymphocyte apoptosis is surprising. In {{U}} {{U}} 7 {{/U}} {{/U}}was the longest study of its kind, pigs were fed RPS over 14 weeks to {{U}} {{U}} 8 {{/U}} {{/U}}the effect of starch on bowel health. "The use of raw potato starch in this experiment is {{U}} {{U}} 9 {{/U}} {{/U}}to simulate the effects of a diet high in resistant starch," said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona, Spain. Humans do not eat {{U}} {{U}} 10 {{/U}} {{/U}}potatoes, but they do eat a lot of foods that contain resistant starch, such as cold boiled potatoes, legumes, grains, green bananas, pasta and cereals. About 10 percent of the starch eaten by human is resistant starch—starch that is not {{U}} {{U}} 11 {{/U}} {{/U}}in the small intestine and so is shunted into the large intestine where it ferments. Starch consumption is thought to reduce the {{U}} {{U}} 12 {{/U}} {{/U}}of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS). Immunology expert Lena Ohman's team {{U}} {{U}} 13 {{/U}} {{/U}}found that the overall lymphocyte levels do not vary for IBS patients, but that lymphocytes are transferred from the peripheral blood to the gut, which support the hypothesis of IBS being {{U}} {{U}} 14 {{/U}} {{/U}}least partially an inflammatory disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interesting, and a diet of resistant starch may be worth {{U}} {{U}} 15 {{/U}} {{/U}}in IBS patients. Ohman is currently at the Department of Internal Medicine, Goteborg University, Sweden. The study is published in the Journal Chemistry and Industry, the magazine of the SCI.

单选题 Passive Smoking Is Workplace Killer Pressure mounted on Britain on Monday to take action on {{U}} {{U}} 1 {{/U}} {{/U}}smoking with new research showing second-hand smoke {{U}} {{U}} 2 {{/U}} {{/U}}about one worker each week in the hospitality industry. Professor Konrad Jamrozik, of Imperial College in London, told a conference on environmental tobacco that second-hand {{U}} {{U}} 3 {{/U}} {{/U}}kills 49 employees in pubs, bars, restaurants and hotels each year and contributes to 700 deaths from lung cancer, heart {{U}} {{U}} 4 {{/U}} {{/U}}and stroke across the total national work force. "Exposure in the hospitality {{U}} {{U}} 5 {{/U}} {{/U}}at work outweighs the consequences of exposure of living {{U}} {{U}} 6 {{/U}} {{/U}}a smoker for those staff," Jamrozik said in an interview. Other {{U}} {{U}} 7 {{/U}} {{/U}}have measured the levels of exposure to passive smoking but Jamrozik calculated how it would translate into avoidable deaths. His findings are {{U}} {{U}} 8 {{/U}} {{/U}}on the number of people working in the hospitality industry in Britain, their exposure to second-hand smoke and their {{U}} {{U}} 9 {{/U}} {{/U}}of dying from it. Jamrozik said the findings would apply to {{U}} {{U}} 10 {{/U}} {{/U}}countries in Europe because, to a greater or {{U}} {{U}} 11 {{/U}} {{/U}}extent, levels of smoking in the community are similar. Professor Carol Black, president of the Royal College of Physicians, which sponsored the meeting said the research is proof of the need for a ban on smoking in {{U}} {{U}} 12 {{/U}} {{/U}}places. "Environmental tobacco smoke in pubs, bars, restaurants and other public places is {{U}} {{U}} 13 {{/U}} {{/U}}damaging to the health of employees as well as the general public," she said in a statement. "Making these places smoke free not only protects vulnerable staff and the public, it will {{U}} {{U}} 14 {{/U}} {{/U}}help over 300,000 people in Britain to stop smoking completely," she added. Ireland recently became the first country to introduce a national ban on smoking in public {{U}} {{U}} 15 {{/U}} {{/U}}. New York and parts of Australia have taken similar measures.

Dr. Elizabeth K. Vig of the University of Washington in Seattle and colleagues interviewed 26 men with{{U}} (52) {{/U}}heart disease or cancer. The men were asked to describe good and bad deaths, and they also answered{{U}} (53) {{/U}}about their preferences for dying. "In this small study, terminally ill men described good and bad deaths{{U}} (54) {{/U}}," Vig said. "They did not hold the same views about such issues{{U}} (55) {{/U}}the presence of others at the very end of life or preferred location of death." Many of the men considered{{U}} (56) {{/U}}in their sleep to be a good death. The reasons were varied and included not{{U}} (57) {{/U}}that death was imminent (即将发生的), and that death would be painless. For close to half of the men, a prolonged (拖延的) death was{{U}} (58) {{/U}}a bad death. Some of the men associated a prolonged death with prolonged pain,{{U}} (59) {{/U}}others thought a prolonged death would be difficult for their families. Most men said that their{{U}} (60) {{/U}}were very important to them, but this did not mean that they wanted relatives close at the{{U}} (61) {{/U}}of death. "Valuing family did not also{{U}} (62) {{/U}}wanting family present at the very end of life," Vig said. "In fact, some expressed concerns{{U}} (63) {{/U}}burdening loved ones," Vig said. For instance, some men were worried about the emotional or{{U}} (64) {{/U}}impact on their family members, according to the Washington researcher. Some were worried{{U}} (65) {{/U}}their need for care would be a burden on their families, she said.

单选题Travel across Africa For six hours we shot through the barren (荒芜的) landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I"d bought in a market in Mozambique. Southern Africa was full of stories and visions. We were almost drunk on sensations. The roaring of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana. And then the other things: dogs in the streets, whole families in Soweto living in one room, a kilometer from clean water. As we drove towards the setting sun, the quietness fell over us. The road was empty—we hadn"t seen another car for hours. And as I drove, something caught my eye. Something was moving close enough to touch them, to smell their hot breath. I didn"t know how long they had been there next to us. I shouted to Dan: Look! He was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, and then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened. "Wild horses?" he said. Why didn"t you wake me up, Sophia? I tried. But they were gone after a few seconds. Are you sure you didn"t dream it? You were the one who was sleeping! "Typical." he said. The best photos are the ones we never take. We checked into a dusty hotel and slept the sleep of the dead.

单选题Retirement Brings Most a Big Health Boost The self-reported health of the newly retired improves so much that most feel eight years younger, a new European study suggests. This happy news was true of almost everyone except a small minority only 2 percent who had experienced "ideal" conditions in their working life, anyway. "The results really say three things: that work puts an extra burden on the health of older workers, that the effects of this extra burden are largely relieved by retirement and, finally, that both the extra burden and the relief are larger when working conditions are poor," said Hugo Westerlund, lead author of a study published online Nov. 9 in The Lancet. "This indicates that there is a need to provide opportunities for older workers to decrease the demands in their work out of concern of their health and well-being. " But of course, added Westerlund, who is head of epidemiology at the Stress Research Institute at Stockholm University in Sweden "not all older workers suffer from poor perceived health. Many are indeed remarkably healthy and fit for work. But sooner or later, everyone has to slow down because of old age catching up. " Last week, the same group of researchers reported that workers slept better after retirement than before. "Sleep improves at retirement, which suggests that sleeping could be a mediator between work and perception of poor health, "Westerlund said. This study looked at what the same 15,000 French workers, most of them men, had to say about their own health up to seven years pro-retirement and up to seven years post-retirement. As participants got closer to retirement age, their perception of their own health declined, but went up again during the first year of retirement. Those who reported being in poorer health declined from 19.2 percent in the year prior to retirement to 14.3 percent by the end of the first year after retiring. According to the researchers, that means post-retirement levels of poor health fell to levels last seen eight years previously. The changes were seen in both men and women, across different occupations, and lasted through the first seven years of not punching the clock. Workers who felt worse before retirement and had lower working conditions reported greater improvements as soon as they retired, the team found.

But in the study of five wealthy countries, published in the journal Health Affairs, researchers found no single nation had clearly the worst or best health care system. Gerard Anderson at Johns Hopkins University's school of public health and colleagues came up with a list of 21 health fields they could evenly compare across the five countries--Australia, Canada, Britain, New Zealand and the United States. "None of the five countries is consistently the best or the worst on all 21 indicators. " Anderson said during a telephone briefing for reporters. "If you are looking for the place to get the best care. there isn't a single place. Every country has at least one indicator where it scores the best of the five countries and each country has at least one indicator(指标) where it scores the worst of the five countries. " But,he said, the United States is not getting value for money. "The United States should be particularly concerned about these results, given that we spend twice as much on health care as any other country. So spending more doesn't necessarily result in better outcomes. " Anderson's group of international health experts sponsored by The Commonwealth (联邦)Fund spent five years working on the study, getting the latest possible data from the five countries on areas such as breast cancer and leukemia (白血病) survival, suicide rates, death rates from asthma (哮喘 ), vaccination (种痘) rates and cancer screening.
