　　Exercise is one of the few factors with a positive role in long　term maintenance of body weight. Unfortunately, that message has　not gotten through to the average American, that would rather try __1__ switching to "light" beer and low-calorie bread than increase physical　exertion. The Centers for Disease Control, for example, found　that fewer than one-fourth of overweight adults were trying to shed __2__ pounds said they were combining exercise with their diet.

　　In rejecting exercise, some people may be discouraged too　much by calorie-expending charts; for example, one would have to __3__ briskly walk three miles just to work the 275 calories in one __4__ delicious Danish pastry. Even exercise professionals concede half a　point here. "Exercise in itself is a very tough way to lose weight," __5__ says York Onnen, the program director of the President's Council on __6__ Physical Fitness and Sports.

　　Therefore, exercise's supporting role in weight reduction is vital. __7__ A study at the Boston University Medical Center of overweight police　officers and other public employees confirmed that those who diet __8__ without exercise regained almost all their old weight, while those　who worked exercise into their daily routine maintained their new weight.

　　If you decide to start walking one mile a day, the added exercise　could burn an extra 100 calories daily. In a year's time, assumed no __9__ increase in food takein, you could lose ten pounds. By increasing the __10__ distance of your walks gradually and making other dietary adjustments,you may lose even more weight.

　　答案：

　　1.that--who.that从句修饰的是the average American，而且它是一个非限定性定语从句，而that无法引导一个非限定性定语从句，所以应把that改为who。

　　2.adults^--who.found后接的从句中主要的动词应该是said，而不是try to shed pounds，所以应该在were前面加上who构成定语从句修饰overweight adults。

　　3.expending--expenditure.由于caloric是形容词，表示“属于或者关于卡的”，它后面不能接动词的-ing形式，而且expending和charts的关系也不成立，所以应该改为名词expenditure。

　　4.work^--off.work off有消耗之意，符合文义。

　　5.in--by(直接把in 去掉也可以吧?).in itself 表示“本身，本质上”，而我们都知道锻炼是一减肥的好方法，只是不能仅靠锻炼，还需配之以适当的饮食控制，所以应该把in itself换成by itself，表示“单独”。

　　6.the(program)--/.在用作同位语表示独一无二的职位的名词之前，通常用零冠词。

　　7.Therefore--Still/Neverthless.根据上下文，这里要表达的关系是让步，不是因果。

　　8.diet--dieted.这里叙述的是过去的一项研究。

　　9.assumed--assuming.assume和you的关系应是主动的，所以应改为assuming。

　　10.takein--intake.take in 表示“摄入，吸收”，它的名词形式不是take in，而是 intake。
