阅读理解A history of long and effortless success can be a dreadful handicap, but, if properly handled, it may become a driving force. When the United States entered just such a glowing period after the end of the Second World War, it had a market eight times larger than any competitor, giving its industries unparalleled economies of scale. Its scientists were the world''s best, its workers were the most skilled. America and Americans were prosperous beyond the dreams of the Europeans and Asians whose economies the war had destroyed. 　　It was inevitable that this primacy should have narrowed as other countries grew richer. Just as inevitably, the retreat from predominance proved painful. By the mid-1980s Americans had found themselves at a loss over their fading industrial competitiveness. Some huge American industries, such as consumer electronics ,had shrunk or vanished in the face of foreign competition. By 1987 there was only one American television maker left, Zenith. (Now there is none: Zenith was bought by South Korea''s LG Electronics in July.)Foreign-made cars and textiles were sweeping into the domestic market. America''s machine-tool industry was on the ropes. For a while it looked as though the making of semiconductors, which America had invented and which sat at the heart of the new computer age, was going to be the next casualty. 　　All of this caused a crisis of confidence. Americans stopped taking prosperity for granted. They began to believe that their way of doing business was failing, and that their incomes would therefore shortly begin to fall as well. The mid-1980s brought one inquiry after another into the causes of America''s industrial decline. Their sometimes sensational findings were filled with warnings about the growing competition from overseas. 　　How things have changed! In 1995 the United States can look back on five years of solid growth while Japan has been struggling. Few Americans attribute this solely to such obvious causes as a devalued dollar or the turning of the business cycle. Self-doubt has yielded to blind pride. "American industry has changed its structure, has gone on a diet, has learnt to be more quick-witted, "according to Richard Cavanagh, executive dean of Harvard''s Kennedy School of Government. "It makes me proud to be an American just to see how our businesses are improving their productivity," says Stephen Moore of the Cato Institute, a think-tank in Washington D. C. And William Sahlman of the Harvard Business School believes that people will look back on this period as "a golden age of business management in the United States."

阅读理解Using the Mind to Fight Diseases A) Psychology has a new application in the field of medicine

阅读理解 After retirement from medical research, my wife and I built our home in a gated community surrounded by yacht clubs and golf courses on Hilton Head Island. But when I left for the other side of the island, I was traveling on unpaved roads lined with leaky cottages. The 'lifestyle' of many of the native islanders stood in shocking contrast to my comfortable existence By talking to the local folks, I discovered that the vast majority of the maids, gardeners, waitresses and construction workers who make this island work had little or no access to medical care. It seemed outrageous to me. I wondered why someone didn't do something about that. Then my father's words, which he had asked his children daily when they were young, rang in my head again: 'What did you do for someone today?' Even though my father had died several years before, I guess I still didn't want to disappoint him. So I started working on a solution. The island was full of retired doctors. If I could persuade them to spend a few hours a week volunteering their services, we could provide free primary health care to those so desperately in need of it. Most of the doctors I approached liked the idea, so long as they could be relicensed without troubles. It took one year and plenty of persistence, but I was able to persuade the state legislators to create a special license for doctors volunteering in not-for-profit clinics. The town donated land, local residents contributed office and medical equipment and some of the potential patients volunteered their weekends ornamenting the building that would become the clinic. We named it Volunteers in Medicine and we opened its doors in 1994, fully staffed by retired physicians, nurses and dentists as well as nearly 150 nonprofessional volunteers. That year we had 5,000 patient visits; last year we had 16,000. Somehow word of what we were doing got around. Soon we were receiving phone calls from retired physicians all over the country, asking for help in starting VIM clinics in their communities. We did the best we could--there are now 15 other clinics operating--but we couldn't keep up with the need. Yet last month I think my father's words found their way up north, to McNeil Consumer Healthcare, the maker of Tylenol (泰诺: 一种感冒药). A major grant from McNeil will allow us to respond to these requests and help establish other free clinics in communities around the country.

阅读理解 When it comes to health, which is more important, nature or nurture? You may well think your genes are a more important predictor of health and ill health. Not so fast. In fact, it transpires that our everyday environment outweighs our genetics, big time, when it comes to measuring our risk of disease. The genome is out—welcome the exposome. 'The exposome represents everything a person is exposed to in the environment, that's not in the genes,' says Stephen Rappaport, environmental health scientist at the University of California, Berkeley. That includes stress, diet, lifestyle choices, recreational and medicinal drug use and infections, to name a few. 'The big difference is that the exposome changes throughout life as our bodies, diets and lifestyles change,' he says. While our understanding of the human genome has been growing at an exponential rate over the last decade, it is not as helpful as we hoped in predicting diseases. 'Genes only contribute 10 percent to the overall disease burden,' says Rappaport. 'Knowing genetic risk factors can prove absolutely futile ,' says Jeremy Nicholson at Imperial College London. He points to work by Nina Paynter at the Brigham and Women's Hospital in Boston, who investigated the effect of 101 genetic markers implicated in heart disease. After following over 19,000 women for 12 years, she found these markers were not able to predict anything about the incidence of heart disease in this group. On the other hand, the impact of environmental influences is still largely a mystery.' There's an imbalance between our ability to investigate the genome and the environment,' says Chris Wild, director of the International Agency for Research on Cancer, who came up with the idea of the exposome. In reality, most diseases are probably caused by a combination of the two, which is where the exposome comes in. 'The idea is to have a comprehensive analysis of a person's full exposure history,' says Wild. He hopes a better understanding of exposures will shed a brighter light on disease risk factors. There are likely to be critical periods of exposure in development. For example, the time from birth to 3 years of age is thought to be particularly important. 'We know that this is the time when brain connections are made, and that if you are obese by this age, you'll have problems as an adult,' says Nicholson.

阅读理解 Have you switched off your computer? How about your television? Your video? Your CD player? And even your coffee percolator? Really switched them off, not just pressed the button on some control panel and left your machine with a telltale bright red light warning you that it is ready to jump back to life at your command? Because if you haven't, you are one of the guilty people who are helping to pollute the planet. It doesn't matter if you've joined the neighborhood recycling scheme, conscientiously sorted your garbage and avoided driving to work. You still can't sleep easy while just one of those little red lights is glowing in the dark. The awful truth is that household and office electrical appliances left on stand-by mode are gobbling up energy, even though they are doing absolutely nothing. Some electronic products—such as CD players—can use almost as much energy on stand-by as they do when running. Others may use a lot less, but as your video player spends far more hours on stand-by than playing anything, the wastage soon adds up. In the US alone, idle electronic devices consume enough energy to power cities with the energy needs of Chicago or London—costing consumers around $1 billion a year. Power stations fill the atmosphere with carbon dioxide just to do absolutely nothing. Thoughtless design is partly responsible for the waste. But manufacturers only get away with designing products that waste energy this way because consumers are not sensitive enough to the issue indeed, while recycling has caught the public imagination, reducing waste has attached much less attention. But 'source reduction', as the garbage experts like to call the art of not using what you don't need to use, offers enormous potential for reducing waste of all kinds. With a little intelligent shopping, you can cut waste long before you reach the recycling end of the chain. Packaging remains the big villain. One of the hidden consequences of buying products grown or made all around the world, rather than produced locally, is the huge amount of packaging needed to transport them safely. In the US, a third of the solid waste collected from city homes is packaging. To help cut the waste and encourage intelligent manufacturers the simplest trick is to look for ultra-light packaging. The same arguments apply to the very light but strong plastic bottles that are replacing heavier glass alternatives, thin-walled aluminum cans, and cartons made of composites that wrap up anything drinkable in an ultra-light package. There are hundreds of other tricks you can discuss with colleagues while gathering around the proverbial water cooler—filling up, naturally, your own mug rather than a disposable plastic cup. But you don't need to go as far as one website which tells you how to give your friends unwrapped Christmas presents. There are limits to source correctness.
