For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and blacken the corresponding letter on the ANSWER SHEET with a pencil.Questions 41 to 45 are based on the following passage: Prior to the 20th century, many languages with small numbers of speakers survived for centuries. The increasingly interconnected modern world makes it much more difficult for small language munities to live in relative isolation, a key factor in language maintenance and preservation. It remains to be seen whether the world can maintain its linguistic and cultural diversity in the centuries ahead. Many powerful forces appear to work against it :population growth, which pushes migrant populations into the world’s last isolated locations。 global telemunications and mass media。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 ine. 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 jobs by 2012 was as much a sign of it’s“l(fā)egacy ” health –care costs as of the ills of the car industry.

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 “socialized medicine” of Canada and Europe. In fact, even if much of the administration is done privately, around 60% of America’s heathcare 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 babyboomers run up their Medicare bills and ever more employers avoid providing healthcare coverage. America is , in effect, heading towards a version of socialized medicine by default. problems mentioned in the passage include all the following EXCEPT____
