[单项选择]It was about 2 p.m. on Mar. 9 when three Nucor Corp. electricians got the call from their colleagues at the Hickman (Ark.) plant. It was bad news: Hickman’s electrical grid had failed. For a minimill steelmaker like Nucor, which melts scrap steel from autos, dishwashers, mobile homes, and the like in an electric arc furnace to make new steel, there’s little that could be worse. The trio immediately dropped what they were doing and headed out to the plant.
No supervisor had asked them to make the trip, and no one had to. They went on their own. There wasn’t any direct financial incentive for them to blow their weekends, no extra money in their next paycheck, but for the company their, contribution was huge.
What’s most amazing about this story is that at Nucor it’s not considered particularly remarkable. "It could have easily been a Hickman operator going to help the Crawfordsville [Ind. ] mill," says Executive Vice-President John J. Ferriola "It happens daily." Nucor has nurt

For about three centuries we have been doing science, trying science out, using science for the construction of what we call modern civilization. Every indispensable item of contemporary technology, from canal locks to dial telephone-to penicillin, was pieced together to form the analysis of data provided by one or another series of scientific experiments. Three hundred years seems a long time for testing a new approach to human inter-living, long enough to settle back for critical appraisal of the scientific method, maybe even long enough to vote on whether to go no with it or not. There is an argument.
Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolutions, summoning urgent crowds into the streets any day on the issue of nuclear energy.

[单项选择]About three-quarters of Americans, according to surveys, think the country is on the wrong track. About two-thirds of the public disapprove of the job performance of President Bush, and an even higher number disdain Congress. The media are excited about the prospect of a wealthy businessman running for President as an independent who could tap into broad public disgruntlement with the partisan politicians in Washington.
2007 Yes. But also 1992, The main difference between the two situations is that Michael Bloomberg is richer—and saner—than Ross Perot. But one similarity might be this: the American people were wrong then and may be wrong now. The widespread pessimism in the early 1990s about the course of the country turned out to be unwarranted. The rest of the decade featured impressive economic growth, a falling crime rate, successful reform of the welfare system and a reasonably peaceful world. Perhaps the problems weren’t so bad in the first place, or perhaps the political sy
A. The Americans had unwarranted pessimism about their state affairs.
