问题 Exercise is one of the few factors with a positive role in longterm maintenance of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and lowcalorie bread than increase physical exertion. The Centers for Disease Control, for example, found that fewer than onefourth of overweight adults who were trying to shed pounds said they were combining exercise with their diet.
    In rejecting exercise, some people may be discouraged too much by calorieexpenditure charts, for example, one would have to briskly walk three miles just to work off the 275 calories in one delicious Danish pastry. Even exercise professionals concede half a point here. "Exercise by itself is a very tough way to lose weight." said York Onnen, program director of the President’s Council on Physical Fitness and Sports.
    Still exercise’s supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.
    If you have been sedentary (极少活动的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year’s time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
[br] What was confirmed by the Boston University Medical Center’s study?

选项 A、Controlling one’s calorie intake is more important than doing exercise.
B、Even occasional exercise can help reduce weight.
C、Weight reduction is impossible without exercise.
D、One could lose ten pounds in a year’s time if there’s no increase in food intake.

答案 C

解析 推理题。依据在第三段首句“Still exercise’s supporting role in weight reduction is vital.”及本段“…confirmed that those who dieted without exercise regained almost all their old weight,while those who worked exercise into their daily routine maintained their new weight.”“……确认那些不运动的人恢复了原来体重,而把运动纳入日常生活的人保持了新的体重”。因此,可以推断C项“不运动减肥是不可能的”为该题答案。A项与原文信息相反;B项错在occasional,第三段最后一句中的“daily routine”和第四段提到的“每天步行一英里……一年后体重会减少10磅”都可以排除B项,D项不是该研究中心证实的结果.
