delicious Danish pastry. Even exercise professionals concede half a
point here. "Exercise in itself is a very tough way to lose weight," __5__

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

答案及解析：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。
