单选题{{B}}第二篇{{/B}} {{B}} Obesity: the Scourge of the Western World{{/B}} Obesity is rapidly becoming a new scourge of the western world, delegates agreed at the 11th European Conference on the issue in Vienna Wednesday to Saturday. According to statements before the opening of the conference -- of 2,000 specialists from more than 50 countries -- 1.2 billion people worldwide are overweight, and 250 million are obese. Professor Bernhard Ludvik of Vienna General Hospital said, "Obesity is a chronic illness, fin Germany, 20 per cent of the people are already affected, but in Japan only one per cent." But he said that there was hope for sufferers thanks to the new scientific discoveries and medication. Professor Friedrich Hopichler of Salzberg said, "We are living in the new age (but) with the metabolism of a stone-age man." "I have just been to the United States. It is really terrible. A pizza shop is springing up on every corner. We have been overrun by fast food and Coca-Cola-ization. " Many of the experts stressed that obesity was a potential killer. Hopichler said, "Eighty percent of all diabetics are obese, also fifty per cent of all. patients with high blood pressure and fifty per cent with adipose tissue complaints." "Ten per cent more weight means thirteen per cent more risk of heart disease. Reducing one's weight by ten per cent leads to thirteen per cent lower blood pressure." Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs. "Though the health insurance pays for surgery (such as reducing the size of the stomach) when the body-mass index5 is more than 40. That is equivalent to a weight of 116 kilograms for a height of 1.70 meters. One should start earlier." Ludvik said that prevention should begin in school. "Child obesity ( fat deposits) correlates with the time which children spend in front of TV sets." The consequences were only apparent later on. No more than fifteen per cent of obese people lived to the average life expectancy for their population group.

On his desk were small plates containing the germs. {{U}}(51) {{/U}} evening, he forgot to cover one of the plates. When he arrived the next morning, he found a spot of green mould(霉菌)in one plate. This is not strange because the room was rather damp(潮湿) ,with {{U}}(52) {{/U}} one window. But Fleming did not throw out the spoiled plate, be cause something unusual caught {{U}}(53) {{/U}} attention. On the uncovered plate, near the green mould, the germs {{U}}(54) {{/U}}. That meant that the mould had killed the germs there. Fleming watched the mould grow {{U}}(55) {{/U}} several days. As the green mould spread, it killed more and {{U}}(56) {{/U}} germs. Fleming began to study the mysterious mould. It grew and grew. Then he noticed tiny drops of liquid on the surface of the mould. Perhaps this was the chemical that was destroying the germs. Fleming drew off the liquid, drop by drop. He put this liquid in a test tube, and it {{U}}(57) {{/U}} the germs in the tube. He called the {{U}}(58) {{/U}} penicillin. Fleming published his finding in a British medical journal {{U}}(59) {{/U}} 1929. But for ten years, while he continued to experiment with penicillin, his discovery was largely ignored near the medical world. Then in 1938 a team of British scientists happened to {{U}}(60) {{/U}} about Fleming's findings in an old medical journal. They made further {{U}}(61) {{/U}} with the drug. They tested it on animals and then {{U}}(62) {{/U}} human beings. In 1941, it was declared safe for use on humans. Soon penicillin was produced in large quantity and was used to {{U}}(63) {{/U}} many infections(感染). Penicillin is a very powerful drug. {{U}}(64) {{/U}} can treat many kinds of infections. However, it has some bad effects. Sometimes it causes a skin problem or a light fever. And it can be fatal for people {{U}}(65) {{/U}} are allergic(过敏性的)to it. That is why before you take a penicillin shot, the doctor gives you a test shot first.

单选题Passive Smoking Is Workplace Killer Pressure mounted on Britain on Monday to take action on 1 smoking with new research showing second-hand smoke 2 about one worker each week in the hospitality industry (服务) Professor Knorad Jamrozik, of Imperial (帝国的) College in London, told a conference on environmental tobacco that second-hand 3 kills 49 employees in pubs, bars, restaurants and hotels each year and contributes to 700 deaths from lung cancer, heart 4 and stroke across the total national workforce. "Exposure in the hospitality 5 at work outweighs (超过) the consequences of exposure of living 6 a smoker for those staff," Jamrozik said in an interview. Other 7 have measured the levels of exposure to passive smoking but Jamrozik calculated how it would translate into avoidable deaths. His findings are 8 on the number of people working in the hospitality industry in Britain, their exposure to second-hand smoke and their 9 of dying from it. Jamrozik said the findings would apply to 10 countries in Europe because, to a greater or 11 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 12 smoking in public places. "Environmental tobacco smoke in pubs, bars, restaurants and other public places is 13 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 (易受伤害的 ) staff and the public, it will 14 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 15 . New York and parts of Australia have taken similar measures.

单选题Coming Soon to a Theater near You! What are special effects? Do you enjoy movies that use a lot of special effects?. Dinosaurs (恐龙) from the distant past! Space battles from the distant future! There has been a revolution in special effects, and it has transformed the movies we see. The revolution began in the mid-1970s with George Lucas's Star Wars, a film that stunned (使震惊) audiences. That revolution continues to the present with dramatic changes in special effects technology. The company behind these changes is Lucas's Industrial Light ＆ Magic (ILM). And the man behind the company is Dennis Muren, who has worked with Lucas since Star Wars. Muren's interest in special effects began very early. At the age of 6, he was photographing toy dinosaurs and spaceships. At 10, he had an 8 millimeter movie camera and was making these things move through stop motion. (Stop-motion is a process in which objects are shot with a camera, moved slightly, shot again, and so on. When the shots are put together, the objects appear to move.) Talk to Muren and you'll understand what ILM is all about; taking on new challenges. By 1989, Muren decided he had pushed the old technology as far as it would go. He saw computer graphics(图像)(CG)technology as the wave of the future and took a year off the master it. With CG technology, images can be scanned into a computer for processing, for example, and many separate shots can be combined into a single image. CG technology has now reached the point, Muren says, where special effects can be used to do just about anything so that movies can tell stories better than ever before. The huge success of Jurassic Park and its sequel (续集), The Lost World, the stars of which were computer-generated dinosaurs, suggests that this may very well be true.
