專業八級考試改錯突擊練習題：

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 switching to __1__

"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; __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__

the program director of the President's Council on Physical Fitness and Sports. __6__

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 without exercise regained almost all their old weight, __8__

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 increase in __9__

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

and making other dietary adjustments,you may lose even more weight.

答案：

1.that--who.that從句修飾的是the average American，而且它是一個非限定性定語從句，而that無法引導一個非限定性定語從句，所以應把that改為who。

2.adults^--who.found后接的從句中主要的動詞應該是said，而不是try to shed pounds，所以應該在were前面加上who構成定語從句修飾overweight adults。

3.expending--expenditure.由于caloric是形容詞，表示“屬于或者關于卡的”，它后面不能接動詞的-ing形式，而且expending和charts的關系也不成立，所以應該改為名詞expenditure。

4.work^--off.work off有消耗之意，符合文義。

5.in--by(直接把in 去掉也可以吧?).in itself 表示“本身，本質上”，而我們都知道鍛煉是一減肥的好方法，只是不能僅靠鍛煉，還需配之以適當的飲食控制，所以應該把in itself換成by itself，表示“單獨”。

6.the(program)--/.在用作同位語表示獨一無二的職位的名詞之前，通常用零冠詞。

7.Therefore--Still/Neverthless.根據上下文，這里要表達的關系是讓步，不是因果。

8.diet--dieted.這里敘述的是過去的一項研究。

9.assumed--assuming.assume和you的關系應是主動的，所以應改為assuming。

10.taken--intake.take in 表示“攝入，吸收”，它的名詞形式不是take in，而是 intake
