' F0 ?) w6 g. k7 V( S+ e L 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。
i' T8 \. A$ C! ~% w 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。' o2 t {4 K8 L6 [1 f, [
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。* s" y4 {' |0 Y: B# N l- S) k7 R) g
4.work^--off.work off有消耗之意,符合文义。
$ _7 S, _; n9 I: l" V 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”。
