单选题 Americans spend billions of dollars each year trying to change their weight with diets, gym memberships and plastic surgery. Trying to live up to the images of 'perfect' models and movie heroes has a dark side: anxiety, depression, as well as unhealthy strategies for weight loss or muscle gain. It also has a financial cost. Having an eating disorder boosts annual health care costs by nearly US$2,000 per person. Why is there both external and internal pressure to look 'perfect'? One reason is that society rewards people who are thin and healthy-looking. Researchers have shown that body mass index is related to wages and income. Especially for women, there is a clear penalty at work for being overweight or obese. Some studies have also found an impact for men, though a less noticeable one. While the research literature is clear that labor market success is partly based on how employers and customers perceive your body image, no one had explored the other side of the question. Does a person's own perception of body image matter to earnings and other indicators of success in the workplace? Our recently published study answered this question by tracking a large national random sample of Americans over a critical time period when bodies change from teenage shape into adult form and when people build their identities. As in other research, women in our sample tend to over-perceive their weight—they think they're healthier than they are—while men tend to under-perceive theirs. We found no relationship between the average person's self-perception of weight and labor market outcomes, although self-perceived weight can influence self-esteem (自尊心), mental health and health behaviors While the continued gender penalty in the labor market is frustrating, our finding that misperceived weight does not harm workers is more heartening. Since employers' perception of weight is what matters in the labor market, changing discrimination laws to include body type as a category would help. Michigan is the only state that prohibits discrimination on the basis of weight and height. We believe expanding such protections would make the labor market more fair and efficient.

单选题" They laughed when I sat down at the piano, but when I started to play... ! " These words may be among the most successful in advertising history. Although the ad has not run for many years, the slogan is still remembered. It was written in 1925 for the V. S. School of Music, to sell home music lessons. The ad has great appeal. It pictures a handsome man sitting at a piano in front of smiling guests. It tells the story of Jack, who has secretly learned to play the piano through a mail-order course. His friends at a party all scoff when he sits at the keyboard. But as he plays the first notes of Beethoven's "Moonlight Sonata," they all amazed. When he finishes his flawless performance, the listeners shower him with applause and praise. Jack tells his friends that he learned to play through the V. S. School of Music. He explains that he was taught through a new method, using no laborious scales and no tiresome practicing. He didn't even have a special talent for music! In the ad, others, too, could increase their popularity and gain happiness. The writer of this ad, John Gaples, called this style the "Walter Mitty approach." Walter Mitty is a character in a short story by James Thurber, who daydreams of taking part in great adventures. Although this ad seems old-fashioned now, many people still dream of such easy social success.
