单选题 Business has slowed, layoffs mount, but executive pay continues to roar-at least so far. Business Week's annual survey finds that chief executive officers (CEOs) at 365 of the largest companies got compensation last year averaging $3.1 million-up 1.3 percent from 1994. Why are the top bosses getting an estimated 485 times the pay of a typical factory worker? That is up from 475 times in 1999 and a mere 42 times in 1980. One reason maybe what experts call the "Lake Wobegon effect". Corporate boards tend to reckon that "all CEOs are above average" -a play on Garrison Keillor's famous line in his public radio show, A Prairie Home Companion, that all the town's children are "above average". Consultants provide boards with surveys of corporate CEO compensation. Since directors are reluctant to regard their CEOs as below average, the compensation committees of boards tend to set pay at an above-average level. The result: pay levels get ratcheted (一步步地增加) up. Defenders of lavish CEO pay argue there is such a strong demand for experienced CEOs that the free market forces their pay up. They further maintain most boards structure pay packages to reflect an executive's performance. They get paid more if their companies and their stock do well. So companies with high-paid CEOs generate great wealth for their shareholders. But the supposed cream-of-the-crop executives did surprisingly poorly for their shareholders in 1999, says Scott Klinger, author of this report by a Boston-based Organization United for a Fair Economy. If an investor had put $10,000 apiece at the end of 1999 into the stock of those companies with the 10 highest-paid CEOs, by year-end 2000 the investment would have shrunk to $8,132. If $10,000 had been put into the Standard & Poor's 500 stocks, it would have been worth $9,090. To Mr. Klinger, these findings suggest that the theory that one person, the CEO, is responsible for creating most of a corporation's value is dead wrong. "It takes many employees to make a corporation profitable." With profits down, corporate boards may make more effort to tame executive compensation. And executives are making greater efforts to avoid pay cuts. Some CEOs, seeing their options "under water" or worthless because of falling stock prices, are seeking more pay in cash or in restricted stock.

单选题Making Light of Sleep All we have a clock located inside our brains. Similar to your bedside alarm clock, your internal clock 1 on a 24-hour cycle. This cycle, 2 a circadian (昼夜节奏的，生理节奏的) rhythm, helps control when you wake, when you eat and when you sleep. Somewhere around puberty (青春期), 3 happens in the timing of the biological clock. The clock pushes forward, so adolescents (青少年) and teenagers are unable to fall asleep as early as they 4 to. When your mother tells you it"s time 5 bed, your body may be pushing you to stay up for several hours more. And the light coming from your computer screen or TV could be pushing you to 6 even later. This shift is 7 for teenagers. But staying up very late and sleeping late can get your body"s clock out of sync (同步) with the cycle of light and dark. It can also make it hard to get out of bed in the 8 and may bring other problems, too. Teenagers are put in a kind of gray cloud 9 they don"t get enough sleep, says Mary Carskadon, a sleep researcher at Brown University in Providence, RI. It 10 their mood and their ability to think and learn. But just like your alarm clock, your internal clock can be reset. In fact, it 11 resets itself every day. How? By using the light it gets through your 12 . Scientists have known for a long time that the light of day and the dark of night 13 important roles in setting our internal clocks. For years, researchers thought that the signals that synchronize the body"s 14 were handled through the same pathways that we use to see. 15 recent discoveries show that the human eye has two separate light-sensing systems. One system allows us to see. The second system tells our body whether it"s day or night.

单选题Mother Nature Shows Her Strength Tornadoes (龙卷风) and heavy thunderstorms moved across the Great Lakes and into Trumbull County on Saturday evening. The storms were dramatic and dangerous. George Snyder was driving the fire truck down Route 88 when he first noticed that a funnel (漏斗状的) cloud was behind him. "I stopped the truck and watched the funnel cloud. It was about 100 feet off the ground and I saw it go up and down for a while. It was moving toward Bradley Road and then suddenly it disappeared." Snyder said. Snyder only saw one of the funnel clouds that passed through northeastern Ohio on Saturday. In Trumbull County, a tornado turned trees onto their sides. Some trees fell onto houses and cars. Other trees fell into telephone and electrical wires as they went down. Amanda Symcheck was having a party when the storm began. "I knew something was wrong," he said. "I saw the sky go green and pink (粉红色). Then it sounded like a train rushing toward the house. I started crying and told everyone to go to the basement for protection." The tornado caused a 10t of damage to cars and houses in the area. It will take a long time and much money to repair everything. There was also serious water damage from the thunderstorms. The heavy rains and high wind caused the power to go out in many homes. The storms caused serious flooding in areas near the river. More than four inches of rain fell in parts of Trumbull County. The river was so high that the water ran into streets and houses. Many streets had to be closed to cars and trucks because of the high water. This made it difficult for fire trucks, police cars, and other rescue vehicles to help people who were in trouble. Many people who live near the river had to leave their homes for their own safety. Some people reported five feet of water in their homes. Local and state officials opened emergency shelters for the people who were evacuated (撤走). The Red Cross served meals to them. "This was a really intense storm," said Snyder. "People were afraid. Mother Nature can be fierce. We were lucky this time. No one was killed."

单选题 California Gives Green Light to Space Solar Power Energy beamed down from space is one step closer to reality, now that California has given the green light to an agreement that would see the Pacific Gas and Electric Company buy 200 megawatt (兆瓦) of power beamed down from solar-power satellites beginning in 2016. But some major challenges will have to be overcomed if the technology is to be used widely. A start-up company called Solaren is designing the satellites, which it says will use radio waves to beam energy down to a receiving station on Earth. The attraction of collecting solar power in space is the almost uninterrupted sunshine available in eosynchronous (与地球同步的) orbit. Earth-based solar cells, by contrast, can only collect sun light during daytime and when skies are clear. But space-based solar power must grapple (努力克服) with the high cost per kilogram of launching things into space, says Richard Schwartz of Purdue University in West Lafayette, Indiana, "If you're talking about it being economically viable or power of the Earth, it's a tough go." he says. Cal Boerman, Solaren's director of energy services, says the company designed its satellites with a view to keeping launch costs down. "We knew we had to come up with a different, revolutionary design, " he says. A patent the company has won describes ways to reduce the system's weight, including using inflatable minors to focus sunlight on solar cells, so a smaller number cancollect the same amount of energy. But using minors introduces other challenges, including keeping the solar cells from overheating, says Schwartz. "You have to take care of heat dissipation(散发)because you're now concentrating a lot of energy in one place," he says. According to the company's patent, Solaren's solarcells will be connected to radiators to help keep them cool. Though Boerman says the company believes it can make space-based solar power work, it is not expecting to crowd out other forms of renewable energy. Laws in California and other states requireincreasing use of renewable energy in coming years, he points out. "To meet those needs, we're going to need all types of renewable energy sources," he says.

单选题New U.S. Plan for Disease Prevention Urging Americans to take responsibility for their health, Health and Human Services Secretary Tommy Thompson on Tuesday launched a $15 million program to try to encourage 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 prevent them, including better diet and increased exercise. "In the United States today, 7 of 10 deaths and the vast majority of serious illness, disability and health care costs are caused by chronic diseases," the Health and Human Services Department said in a statement. The causes are often behavior—smoking, poor eating habits and a lack of exercise. "I am convinced that preventing disease by promoting better health is a smart policy choice for our future," Thompson told a conference held to launch the initiative. "Our current health care system is not structured to deal 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 preventable, yet we as a nation are not taking the steps necessary for US to lead healthier, longer lives," he said. The $15 million is slated to go to communities to promote prevention, pushing for changes as simple as building sidewalks to encourage people to walk more. Daily exercise such as walking can prevent and even reverse 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 risk of diabetes about what they can do to prevent it and encourage more cancer screening. The American Cancer Society estimates that half of all cancers can be caught by screening, including Pap tests for cervical cancer, mammograms for breast cancer, colonoscopies, and prostate checks. If such cancers were all caught by early screening, the group estimates that the survival rate for cancer would rise to 95 percent.
