But nowhere has a bigger health problem than America. Soaring medical bills are squeezing wages, swelling the ranks of the uninsured and pushing huge firms and perhaps even the government towards bankruptcy. Ford's announcement this week that it would cut up to 30,000 jobs by 2012 was as much a sign of its "legacy" health-care costs as of the ills of the car industry. Pushed by polls that show health care is one of his main domestic problems and by forecasts showing that the retiring baby-boomers will crush the government's finances, George Bush is expected to unveil a reform. plan in next week's state-of-the-union address.
America's health system is unlike any other. The United States spends 16% of its GDP on health, around twice the rich-country average, equivalent to $ 6,280 for every American each year. Yet it is the only rich country that does not guarantee universal health coverage. Thanks to an accident of history, most Americans receive health insurance through their employer, with the government picking up the bill for the poor and the elderly.
This curious hybrid certainly has its strengths. Americans have more choice than anybody else, and their health-care system is much more innovative. Europeans' bills could be much higher if American medicine were not doing much of their Research and Development (R&D) for them. But there are also huge weaknesses. The one most often cited—especially by foreigners—is the army of uninsured. Some 46 million Americans do not have cover. In many cases that is out of choice and, if they fall seriously ill, hospitals have to treat them. But it is still deeply unequal. And there are also shocking inefficiencies: by some measures, 30% of American health spending is wasted.
Then there is the question of state support. Many Americans disapprove of the "so-cialized medicine" of Canada and Europe. In fact, even if much of the administration is done privately, around 60% of America's health-care bill ends up being met by the government. Proportionately, the American state already spends as much on health as the OECD (Organization of Economic Cooperation and Development) average, and that share is set to grow as the baby-boomers run up their Medicare bills and ever more employers avoid providing health-care coverage. America is, in effect, heading towards a version of socialized medicine by default.

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D . Mark your answers on ANSWER SHEET 1.
Office jobs are among the positions hardest hit by computation. Word processors and typists will lose about 93,000 jobs over the next few years, while 57,000 secretarial jobs will vanish. Blame the PC: Today, many executives type their own memos and carry their "secretaries" in the palms of their hands. Time is also hard for stock clerks, whose ranks are expected to decrease by 68,000. And employees in manufacturing firms and wholesalers are being replaced with computerized systems.
But not everyone who loses a job will end up in the unemployment line. Many will shift to growing positions within their own companies. When new technologies shook up the telecomm business, telephone operator Judy Dougherty pursued retraining. She is now a communications technician, earning about $ 64,000 per year. Of course, if you've been a tollbooth collector for the past 30 years, and you find yourself replaced by an E-ZPass machine, it may be of little consolation to know that the telecomm field is booming.
And that's just it: The service economy is fading; welcome to the expertise (专门知识 ) economy. To succeed in the new job market, you must be able to handle complex problems. Indeed, all but one of the 50 highest-paying occupations--air-traffic controller—demand at least a bachelor's degree.
For those with just a high school diploma, it's going to get tougher to find a well-paying job. Since fewer factory and clerical jobs will be available, what's left will be the jobs that computation can't kill: Computers can't clean offices, or care for Alzheimer's patients. But, since most people have the skills to fill those positions, the wages stay painfully low, meaning computation could drive an even deeper wedge between the rich and poor. The best advice now: Never stop learning, and keep up with new technology.
For busy adults, of course, that can be tough. The good news is that the very technology that's reducing so many jobs is also making it easier to go back to school—without having to sit in a classroom. So-called Internet distance learning is hot, with more than three million students currently enrolled, and it's gaining credibility with employers.
