　　Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A., B., C. andD . You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.

　　Passage One
　　Questions 56 to 60 are based on the following passage.
　　Saying they can no longer ignore the rising prices of health care, some of the most influentialmedical groups in the nation are recommending that doctors weigh the costs, not just the effectiveness of treatments, as they make decisions about patient care.The shift, little noticed outside the medical establishment but already controversial inside it,suggests that doctors are starting to redefine their roles, from being concerned exclusively about individual patients to exerting influence on how healthcare dollars are spent. In practical terms, the new guidelines being developed could result in doctors choosing one drug over another for cost 　　reasons or even deciding that a particular treatment—at the end of life, for example—is too expensive. In the extreme, some critics have said that making treatment decisionsbased on cost is a form of rationing. 　　　　Traditionally, guidelines have heavily influenced the practice of medicine, and the latest ones areexpected to make doctors more conscious of the economic consequences of their decisions, even though there's no obligation to follow them. Medical society guidelines are also used by insurancecomoanies to help determine reimbursement (报销) policies. Some doctors see a potential conflict in trying to be both providers of patient care and fmancial
　　Overseers. "There should be forces in society who should be concerned about the budget, but they shouldn't be functioning simultaneously as doctors," said Dr. Martin Samuels at a Boston hospital. He said doctors risked losing the trust of patients if they told patients, "I'm not going to do what I think is best for you because I think it's bad for the healthcare budget in Massachusetts. " Doctors can face some grim trade—offs. Studies have shown, for example, that two drugs are about equally effective in treating macular degeneration, and eye disease. But one costs $ 50 a dose and the other close to $ 2,000. Medicare could save hundreds of millions of dollars a year if everyone used the cheaper drug, Avastin, instead of the costlier one, Lucentis. But the Food and Drug Administration has not approved Avastin for use in the eye. and using it rather than the alternative, Lucentis, might carry an additional, although slight, safety risk. Should doctors consider Medicare's budget in deciding what to use?"I think ethically (在道德层面上) we are just worried about the patient in front of us and not trying to save money for the insurance industry or society as a whole," said Dr. Donald Jensen. Still, some analysts say that there's a role for doctors to play in cost analysis because not many others are doing so. "In some ways," said Dr. Daniel Sulmasy, "it represents a failure of wider society
to take up the issue. "

60. What do some experts say about doctors' involvement in medical cost analysis?

C. It results from society's failure to tackle the problem.
D. It raises doctors' awareness of their social responsibilities.

　　Passage Two
　　Questions 61 to 65 are based on the following passage.
　　Economic inequality is the "defining challenge of our time," President Barack Obama declared in a speech last month to the Center for American Progress. Inequality is dangerous, he argued, not merely because it doesn't look good to have a large gap between the rich and the poor, but because inequality itself destroys upward mobility, making it harder for the poor to escape from poverty. "Increased inequality and decreasing mobility pose a fundamental threat to the American Dream," he said. Obama is only the most prominent public figure to declare inequality Public Enemy No. 1 and the greatest threat to reducing poverty in 　　America. A number of prominent economists have also argued that it's harder for the poor to climb the economic ladder today because the rungs (横档 ) in that ladder have grown farther apart.
　　For all the new attention devoted to the 1 percent, a new damset from the Equality of Opportunity Project at Harvard and Berkeley suggests that, if we care about upward mobility overall, we're vastly exaggerating the dangers of the rich—poor gap. Inequality itself is not a particularly strong predictor of economic mobility, as sociologist Scott Winship noted in a recent article based on his analysis of this data. So what factors, at the community level, do predict if poor children will move up the economic ladder as adtdts? what explains, for instance, why the Salt Lake City metro area is one of the 100 largest metropolitan areas most likely to lift the fortunes of the poor and the Atlanta metro area is one of the least likely?
　　Harvard economist Raj Cherty has pointed to economic and racial segregation, community density,the size of a community's middle class, the quality of schools, commtmity religiosity, and family structure, which he calls the "single strongest correlate of upward mobility. " Chetty finds that communities like Salt Lake City, with high levels of two-parent families and religiosity, are much more likely to see poor children get ahead than communities like Atlanta, with high levels of racial and economic segregation. Chetty has not yet issued a comprehensive analysis of the relative predictive power of each of these factors. Based on my analyses of the data. of the factors that Chetty has highlighted, the following three seem to be most predictive of upward mobility in a given community.

1. Per-capita (人均) income growth
2. Prevalence of single mothers ( where correlation is strong, but negative)
3. Per-capita local government spending In other words, communities with high levels of per-capita income growth, high percentages of two-parent families, and high local government spending-which may stand for good schools-are the most likely to help poor children relive Horatio Alger's rags-to-riches story.
61. How does Obama view economic inequality?
A. It is the biggest obstacle to social mobility.
B. It is the greatest threat to social stability.
C. It is the No. 1 enemy of income growth.
D. It is the most malicious social evil of our time.
62. What do we learn about the inequality gap from Scott Winship's data analysis?
A. It is fast widening across most parts of America.
B. It is not a reliable indicator of economic mobility.
C. It is not correctly interpreted.
D. It is overwhelmingly ignored.
63. Compared with Atlanta, metropolitan Salt Lake City is said to
A. have placed religious beliefs above party politics
B. have bridged the gap between the rich and the poor
C. offer poor children more chances to climb the social ladder
D. suffer from higher levels of racial and economic segregation
64. What is strongly correlated with social mobility according to economist Raj Cherty?
A. Family structure.
B. Racial equality.
C. School education.
D. Community density.
65. What does the author seem to suggest?
A. It is important to increase the size of the middle class.
B. It is highly important to expand the metropolitan areas.
C. It is most imperative to focus our efforts on the elimination of income inequality.
D. It is better to start from the community to help poor children move up the social ladder.
