单选题New Product Will Save Lives Drinking water that looks clean may still contain bugs (虫子), which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Patton, who started Genera five years ago. He and his employees have developed the test together with a British water company. Andy Headland, Genera's marketing director, recently presented the test at a conference in the USA and forecasted good American sales for it. Genera has already sold 11 of its tests at $42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government. Genera was formed five years ago and until October last year had only five employees; it now employs 14. Mr. Headland believes that the company should make around $19 million by the end of the year in the UK alone.

单选题"Salty" Rice Plant Boosts Harvests British scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony Yeo, from Sussex University's School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pair have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice. It is estimated that each year more than 10m hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts (妨碍生长) plants. The problem is caused by several factors. In the tropics, mangroves (红树林) that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. In Latin America, irrigation often causes problems when water is evaporated (蒸发) by the heat, leaving salt deposits behind. Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive. To overcome these problems, Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants' growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be considered for commercial use. Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food in the poorer countries of the world.

单选题 阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 {{B}}Why do people become too fat{{/B}} It is indeed unfortunate that in our modern era of technologic and scientific achievement, there is no adequate explanation for a seemingly simple question: "why do people become too fat and what can be done to prevent it?" about 50 million men and 60 million women between the ages of 18 and 79 are "too fat" and need to reduce excess weight. This amount to about 377 million kg of excess fat for men and 667 million kg for women, or a total of t044 million kg (2297 million 1b) for the United States adult population! If the overfat men and women dieted by consuming 600 fewer calories each day to reduce to a "normal" value of body fat (achievable in 68 days for men and 101 days for women), the reduced caloric intake would equal 5.7 trilling calories. Translating this into fossil fuel energy and considering such factors as the energy required to plant, cultivate, harvest, feed, process, transport, wholesale, retail, acquire, store and cook the food, the annual energy savings would be equal to that required to supply the residential electric demands of Boston, Chicago, san Francisco and Washington DC, or 13 billion gallons of gasoline to fuel 900,000 autos per year. Until recently, the major cause of obesity was believed to be overeating. However, if gluttony (贪食) and overindulgence were the only factors associated with an increase in body fat, the easiest way to permanently reduce would surely to be cut back on food. Of course, if it were that simple, obesity would soon be eliminated as a major health problem. There are obviously other factors operative such as genetic, environmental, and social influences. However, these causes probably overlap. It seems fairly certain that the treatment procedures devised so far, whether they be diets, surgery, drugs, psychologic methods, or exercise, either alone or in combination, have not been particularly successful in solving the problem on a long-term basis. There is nonetheless, optimism that as researchers continue to investigate the many facets of. obesity, as well as to test and quantify various treatment modes, significant progress can be made to conquer this major health problem.

单选题Traffic in Our Cities The volume of traffic in many cities in the world today continues to expand.

单选题New U.S. Plan for Disease Prevention Urging Americans to 1 responsibility for their health, Health and Human Services Secretary Tommy Thompson 2 Tuesday launched a $15 million program to try to 3 communities to do more to prevent chronic diseases like heart disease, cancer and diabetes. The initiative highlights the cost of chronic diseases—the leading causes of death in the United States— and outlines ways that people can 4 them, including better diet and increased exercise. "In the United States today, 7 of 10 deaths and the vast majority of 5 illness, disability and health care costs are 6 by chronic diseases," the Health and Human Services Department said in a statement. The causes are often 7 —smoking, poor eating habits and a lack of exercise. "I am 8 that preventing disease by promoting better health is a smart policy choice for our future," Thompson told at a conference held to launch the initiative. "Our current health care system is not structured to 9 with the escalating costs of treating diseases that are largely preventable through changes in our lifestyle choices." Thompson said heart disease and strokes will cost the country more than $351 billion in 2003. "These leading causes of death for men and women are largely 10 , yet we as a nation are not taking the steps necessary for us to lead healthier, longer lives," he said. The $15 million is 11 to go to communities to promote prevention, pushing for changes as simple as building sidewalks to encourage people to walk more. 12 exercise such as walking can prevent and even 13 heart disease and diabetes, and prevent cancer and strokes. The money will also go to community organizations, clinics and nutritionists who are being encouraged to work together to educate people at 14 of diabetes about what they can do to prevent it and encourage more cancer screening. The American Cancer Society 15 that half of all cancers can be caught by screening, including Pap tests for cervical (子宫颈的) cancer, mammograms (乳房X射线照片) for breast cancer, colonoscopies (结肠镜检查), and prostate (前列腺的) cheeks. If such cancers were all caught by early screening, the group estimates that the survival rate for cancer would rise to 95 percent.

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 hut 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.
