Questions 46 to 50 are based on the following passage:
Everyone, it seems, has a health problem. After pouring billions into the National Health Service, British people moan about dirty hospitals, long waits and wasted money. In Germany the new chancellor, Angela Merkel, is under fire for suggesting changing the financing of its health system. Canada’s new Conservative Prime Minister, Stephen Harper, made a big fuss during the election about reducing the country’s lengthy medical queues. Across the rich world, affluence, ageing and advancing technology are driving up health spending faster than income.
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 it’s “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 (生育高峰期出生的人) will crush the government’s finances, George Bush is to unveil a reform; plan in next week’s state-of –the –union address.
