In rejecting exercise， some people may be discouraged too much by calorie-expending charts; __3__
for example， one would have to 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，” says York Onnen， __5__

food taken， you could lose ten pounds. By increasing the distance of your walks gradually __10__

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