If y

3、ouve ever been on a diet, youve probably discovered, as Whalley did, that taking off extra pounds is a lot easier than keeping them off. In fact, 95 percent of people who lose weight end ap gaining it back.Cycling back and forth between higher and lower weights is not just demoralizing, however. “Th

4、eres some evidence that yo-yoing within a 20-or 30-pound range puts more stress on your heart than carrying those 20 or 30 extra pounds,“ says Stephen Cunnane, a professor of nutritional sciences at the University of Toronto.So how do you maintain the lower weight you achieve after dieting? Research

5、ers and doctors who have studied the five percent of dieters who keep the weight off have found common threads in their approaches and attitudes.

21、Jones, a professor at McGill Universitys School of Dietetics and Human Nutrition. “Even if you eat more, the energy you use for physical activity seems to more than compensate for the increased food intake.

The belief that we respond to nation brands in a similar way as we react to Nike or Nestle is supported

42、by the fact that, some opinions shown in the report are based on our overall feelings rather than rational reasons. For example,U (45) /U, and South Korea scored pretty low in the survey, not due to any logical reasons but simply because many respondents confused it with its Northern neighbor. Howev

43、er, it is not South Korea which got the poorest scores. The struggling brands are Turkey and Russia. The former is bottom of the list and the latter is second from the bottom and considered violent and unstable.The report devotes a lot of attention to the brand of America. Although the United States

44、 is still rated highest for goods and services, its brand has been tarnished by its foreign policy. “U (46) /U.（分数：76.01）(1).（分数：6.91）填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_六、BPart Reading (总题数：1，分数：90.00)BQuestions 47 to 56 are based on the following passage./B
