单选题{{B}}Text 3{{/B}} During the past generation, the American middle-class family that once could count on hard work and fair pay to keep itself financially secure has been transformed by economic risk and new realities. 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 economics. Scholars, policymakers, and critics of all stripes have debated the social implications of these changes, but few have looked at the side effect: family risk has risen as well. Today's families have budgeted to the limits of their new two-paycheck status. As a result, they have lost the parachute they once has 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 savings-account model, with retirees trading much or all of their guaranteed payments for payments depending on investment 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-savings plans are spreading from legislative halls 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 he 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.

单选题The decline of traditional religion in the West has not removed the need for men and women to find a deeper meaning behind existence. Why is the world the way it is and how do we, as conscious individuals, fit into the great scheme? There is a growing feeling that science, especially what is known as the new physics, can provide answer where religion remains vague and faltering. Many people in search of a meaning to their lives are finding enlightenment in the revolutionary developments at the frontiers of science. Much to the bewilderment of professional scientists, quasi-religious cults are being formed around such unlikely topic as quantum physics, space-time relativity, black holes and the big bang. How can physics, with its reputation for cold precision and objective materialism, provide such fertile soil for the mystical? The truth is that the spirit of scientific inquiry has undergone a remarkable transformation over the past 50 years. The twin revolutions of the theory of relativity, with its space-warps and time-warps, and the quantum theory, which reveals the shadowy and unsubstantial nature of atoms, have demolished the classical image of a clockwork universe slavishly unfolding along a predetermined pathway. Replacing this sterile mechanism is a world full of shifting indeterminism and subtle interactions which have no counterpart in daily experience. To study the new physics is to embark on a journey of wonderment and paradox, to glimpse the universe in a novel perspective, in which subject and object, mind and matter, force and field, become intertwined. Even the creation of the universe itself has fallen within the province of scientific inquiry. The new cosmology provides, for the first time, a consistent picture of how physical structures, including space and time, came to exist out of nothing. We are moving towards an understanding in which matter, force, order and creation are unified into a single descriptive theme. Many of us who work in fundamental physics are deeply impressed by the harmony and order which pervades the physical world. To me the laws of the universe, from quarks to quasars, dovetail together so felicitously that the impression there is something behind it all seems overwhelming. The laws of physics are so remarkably clever that they can surely only be a manifestation of genius.

单选题If you choose lobster from a menu, then wherever you are in the world, the odds are that your dinner may have come from Arichat in Nova Scotia. The lobster, trapped off the Canadian coast, would have been driven to Louisville, Kentucky, where, cocooned in gel packs and Styrofoam, it went for a wild ride on the carousels of the UPS superhub, where 17,000 high-speed conveyor belts, carrying more than 8m packages a week, whisk your living lobster to a plane and on onto tables across the globe. John McPhee's new book is about supply lines: how a lobster shares a conveyor belt with Bentley spare parts and jockey underwear. It is about boats, trains and trucks, but mostly it is about the people who drive, tend and love the machines. Don Ainsworth owns an 18-wheeler with "a tractor of such dark sapphire that only bright sunlight could bring forth its color". To wash his truck Mr. Ainsworth uses only water that has either been de-ionised or has undergone reverse-osmosis; anything else leaves spots. "This is as close as a man will ever know," he says, "what it feels like to be a truly gorgeous woman. People give us looks, going thumbs up." He carries chemicals all across North America where his enemies are "gators, bears and four-wheelers", Gators are huge strips of shredded tyre littering the highways and just one of them "can rip off your fuel-crossover line". A bear is a policeman, while a four-wheeler is any vehicle that has fewer than 18 wheels. They buzz around like gnats, seemingly unaware that a real vehicle, one with 18 wheels or more, cannot stop on a dime. The Billy Joe Boling is a towboat which, perversely; pushes 15 barges up the Illinois River. The barges carry 30,000 tons of pig-iron, steel coils, fertilizer and furnace coke. Lashed together with steel cables which are then tightened with cheater bars, the Billy Joe Boling shoves forward a metal raft that is longer than an aircraft carrier. Along the way, the captain copes with bridges, locks, currents, shoals, winter ice 18 inches thick and summer ladies flashing at him. "We broughtl2,000 tons of coke up the Illinois River," the skipper tells the author, "and now we're pushing 14,000 tons of coke down the Illinois River. One day they'll figure it out and put us out of a job." The bosses also want to put the drivers of the coal train out of a job. They dream of automated trains running endlessly along the 1,800 miles between the strip-mines of the Powder River Basin and Georgia's Plant Scherer, the world's largest coal-fired power station. The train that Mr. McPhee rides is a mile and a half long, and has 133 gondolas, each of which carries 115 tons of coal, and the whole trainload will keep Plant Scherer burning for just eight hours. This book will keep you much longer. It is Mr. McPhee at his wise, wry best, writing in top gear which, as Mr. Ainsworth will tell you, is the 18th: "the going home gear, the smoke hole".
