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。# O, q' D! v- E& ?8 [
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。. c8 c( N, D& B8 z9 r, F2 @7 ~' z) J
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。" B: [ O0 H" d9 y; [+ {" X
4.work^--off.work off有消耗之意,符合文义。1 H/ R' U7 {4 G8 s
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”。0 a+ A J$ u* v
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。

8.diet--dieted.这里叙述的是过去的一项研究。
% c: b |9 H- r 9.assumed--assuming.assume和you的关系应是主动的,所以应改为assuming。& a# [) a; K) |! T/ W, h0 v v
10.takein--intake.take in 表示“摄入,吸收”,它的名词形式不是take in,而是 intake。 |
