单选题. People at the lower end of the income scale take more pleasure in their relationships and enjoy caring for and connecting with others, according to a study published Monday in the journal Emotion. By contrast, the positive emotions experienced by people with higher incomes are mainly focused on themselves, the research suggests. "People who are poorer are more reliant on others to get by," said Paul Piff, lead author of the study. "They really prioritize relationships because of their reduced resources, and so they are more likely to really focus on emotions that bind them to one another and find satisfaction and delight in relationships through compassion and love." For the study, Piff and his co-author, Jake P. Moskowitz, surveyed more than 1 500 Americans ranging from 24 to 93 years old. The questions were designed to measure the magnitude of seven emotions experienced each day: amusement, awe, compassion, contentment, enthusiasm, love and pride. Previous research suggests these seven separate feelings are the underlying individual components of general positive emotion. Next, Piff and Moskowitz created statistical models and then analyzed the relationship between income and each of the seven different emotions underpinning happiness. "As income increases, as you rise in the rankings of household income, your tendencies—or daily experiences—of pride, amusement, contentment go up, and your experience of compassion and love and awe go down," Piff said. Enthusiasm was the one emotion unaffected by wealth, with both rich and poor experiencing the same level. There are reasons for expecting wealth and income to shape certain emotions, noted Piff. "Wealth makes you less reliant on other people," he said. "Because of that, you're more likely to focus on emotions that make you feel independent and different from other people—things that make you stand out. Of course these aren't absolute differences; it's not the case that wealthy people don't feel any compassion or any love. It's just that wealth buffers you from experiencing as much of it as other people do." David G. Blanchflower, a professor of economics at Dartmouth, said he was "unimpressed" with the study. Blanchflower, who did not participate in the research, questioned the focus of the study and said it was "unclear what it actually finds." "There is a very large literature showing happiness and life satisfaction is related to income," he said. One example is this study that found higher income increases access to social support, self-esteem and opportunities and so enhances happiness. However, Piff questions whether wealth is "unequivocally (明确地)" linked to increased happiness. The emotions that contribute most to a sense of well-being and health are the emotions that bind you to other people: compassion, love and gratitude, he said. These are the connective glue between people. "It's our ability to be social that is so important to our well-being and our vitality as individuals and as a species." Piff said.1. Why would poor people rank their relationships according to their importance?______

单选题. Is it any wonder that America is also a country of dangerously overweight people? According to a recent study by the National Centre for Health Statistics, the number of adults characterized as overweight in the United States has jumped to an astonishing one-third of the population. Overweight in this case means being about 20 percent or more above a person's desirable weight. Since the figures for "desirable weight" have moved upward over the last decade or so, total poundage—even at 20 percent over—may be considerable. So are the attendant health risks. Excess weight has been linked to cardiovascular disease, hypertension, adult-onset diabetes and some forms of cancer, among other diseases. Once, when work and school and the grocery store were a two-mile hike away, Americans could afford the calories they consume. But not now, not when millions spend four or five hours a day in front of a TV set—along with a bag of chips, a bowl of buttered popcorn and a six-pack—and there's a car or two in every driveway. "There is no commitment to obesity as a public health problem," said Dr. William Dietz, director of clinical nutrition at the New England Medical Centre in Boston. "We've ignored it, and blamed it on gluttony and sloth." If one definition of a public health problem is its cost to the nation, then obesity qualifies. According to a study done by Dr. Graham A. Colditz, who teaches at Harvard Medical School, it cost America an estimated $68.8 billion in 1990. But what's wrong blaming it on gluttony and sloth? True, some unfortunate overweight people have an underlying physical or genetic problem. But for most Americans, the problem is with two of the seven deadly sins. Losing weight is a desperately difficult business. Preventing gain, however, is not. Consumer information is everywhere and there can be few adults who truly believe that hot dogs, fries, a soda and a couple of Twinkies make a good lunch. But they eat them anyway. As more and more Americans became educated to the risks of smoking, more and more Americans gave up the habit. Now it appears that Americans need an intensive education in the risks of stuffing themselves and failing to exercise as well. Given the seductiveness of chocolate and cheese, the couch and the car, that habit will be hard to break. But if an ounce of prevention can obviate a pound of fat, it is well worth the struggle.1.
