单选题Even plants can run a fever, especially when they're under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away — straight up. A decade ago, adapting the infrared scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂) spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest (害虫) problems. Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers". Farmers could then spot-spray, using 40 to 70 percent less pesticide than they otherwise would. The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States." says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Pale3i finds the financial backing which he failed to obtain 10 years ago.

单选题 Many people wrongly believe that when people reach old age, their families place them in nursing homes. They are left in the hands of strangers for the rest of their lives. Their{{U}} (31) {{/U}}children visit them only occasionally, but more often, they do not have any{{U}} (32) {{/U}}visitors. The truth is that this idea is an unfortunate myth imaginary story. In fact, family members provide over 80 percent of the care{{U}} (33) {{/U}}elderly people need. Samuel Preston, a sociologist, studied{{U}} (34) {{/U}}the American family is changing. He reported that by the time the{{U}} (35) {{/U}}American couple reaches 40 years of age, they have more parents than children. {{U}}(36) {{/U}}because people today live longer after an illness than people did years ago, family members must provide long term care. More psychologists have found that all caregivers share a common characteristic: All caregivers believe that they are the best people for the job. In other words, they all felt that they{{U}} (37) {{/U}}do the job better than anyone else. Social workers interviewed caregivers to find out why they took on the responsibility of caring for an elderly relative. Many caregivers believed they had{{U}} (38) {{/U}}to help their relative. Some stated that helping others would{{U}} (39) {{/U}}them feel more useful. Others hoped that by helping{{U}} (40) {{/U}}now, they would deserve care when they became old and dependent. Caring for the elderly and being taken care of can be a mutually satisfying experience for everyone who might be involved.

单选题 During the past generation, the American middle-class family that once could count on hard work and fair play to keep itself financially secure had been transformed by economic risk and new realties. Now a pink slip, a bad diagnosis, or a disappearing spouse can reduce a family from solidly middle class to newly poor in a few months. In just one generation, millions of mothers have gone to work, transforming basic family economies. Scholars, policymakers, and critics of all stripes have debated the social implications of these changes, hut few have looked at the side effect: family risk has risen as well. Today's families have budgeted to the limits of theirs new two-paycheck status. As a result, they have lost the parachuted they once had in times of financial setback—a back-up earner (usually Mom) who could go into the workforce if the primary earner got laid off or fell sick. This "added-worker effect" could support the safety net offered by unemployment insurance or disability insurance to help families weather bad times. But today, a disruption to family fortunes can no longer be made up with extra income from an otherwise-stay-at-home partner. During the same period, families have been asked to absorb much more risk in their retirement income. Steelworkers, airline employees, and now those in the auto industry are joining millions of families who must worry about interest rates, stock market fluctuation, and the harsh reality that they may outlive their retirement money. For much of the past year, President Bush campaigned to move Social Security to a saving-ac- count model, with retirees trading much or all of their guaranteed payments for payments depending on in- vestment returns. For younger families the picture is not any better. Both the absolute cost of healthcare and the share of it borne by families have risen--and newly fashionable health-saving plans are spreading from legislative hails to Wal-Mart workers, with much higher deductibles and a large new dose of investment risk for families' future healthcare. Even demographics are working against the middle class family, as the odds of having a weak elderly parent—and all the attendant need for physical and financial assistance—have jumped eightfold in just one generation. From the middle-class family perspective, much of this, understandably, looks far less like an opportunity to exercise more financial responsibility, and a good deal more like a frightening acceleration of the wholesale shift of financial risk onto their already overburdened shoulders. The financial fallout has begun, and the political fallout may not be far behind.
