Question

Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet.

      In rejecting exercise, some people may be discouraged too much by caloric-expenditure（熱量消耗）charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry(小甜餅). Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says 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 (極少活動的) 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.

4.C

【解析】

試題分析：文章大意：文章強調(diào)鍛煉身體對于減肥和保持體重的重要性，而它的重要性卻常常被美國民眾忽視。

1.細節(jié)理解題。根據(jù)第一段第二行的“that message has not gotten through to the average American”可知，that message指代第一句，exercise的作用還沒有被美國的民眾接受。故選B。

2.細節(jié)理解題。根據(jù)第二段“Exercise by itself is a very tough way to lose weight”可知，通過鍛煉身體來減肥比較辛苦，是一種較為困難的方法。第二段舉的例子是為了說明運動量之大，A項曲解原意；這里講的是exercise，與dieting無關；專家知道鍛煉的積極作用，而不是要加大宣傳。故選B。

3.考查對段落大意的把握。根據(jù)第三段最后一句“while those who worked exercise into their daily routine maintained their new weight”可知，鍛煉身體可以幫助減肥。故選C。

4.考查作者的寫作意圖。作者強調(diào)的是鍛煉身體對保持體重的重要性，A項偷換概念；York Onnen不完全相信鍛煉身體的積極作用；Boston University的研究只是用來印證鍛煉身體的一個例子。故選C。
