GRE官方题库原题116

The following appeared in a health magazine published in Corpora.

"Medical experts say that only one-quarter of Corpora's citizens meet the current standards for adequate physical fitness, even though twenty years ago, one-half of all of Corpora's citizens met the standards as then defined. But these experts are mistaken when they suggest that spending too much time using computers has caused a decline in fitness. Since overall fitness levels are highest in regions of Corpora where levels of computer ownership are also highest, it is clear that using computers has not made citizens less physically fit. Instead, as shown by this year's unusually low expenditures on fitness-related products and services, the recent decline in the economy is most likely the cause, and fitness levels will improve when the economy does."

Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.

题目翻译

医学专家指出C市只有四分之一的市民达到了目前的健康标准，尽管20年前，C的市有一半都达到了那时由国家制定的健康标准。同时专家们认为长时间的使用电脑可能是导致这一现象的原因，但这样的解释可能是错的。由于C市是电脑拥有量最高的地区也是总体健康水平最高的地区，显然使用电脑并没有导致市民体质的下降。相反，今年用于健身产品和服务的花费低的异乎寻常，这表明最近经济的衰退最可能是原因，当经济复苏了健康水平也会随之提高。

题目分析

1. 电脑拥有率未必和健康程度成正比。两者在地域上呈现一直很可能于经济因素有关，比如电脑拥有率高的是富人，他们的饮食非常丰富，有利于他们保持健康。但是这并不能说明健康的下滑与多用电脑有关。

2. 即使身体素质的下滑与电脑的使用没有直接的因果关系，也未必和健身产品的销量有关。因为这两者可能只是时间先后的关系，并没有因果联系。身体素质不是一朝一夕就能毁掉的，所以今年销量的下降未必会对人们的身体素质产生影响，可能只是一个巧合。

3. 即使健身开销下滑是身体素质下降的原因，它也未必和经济情况有关。比如健身开销主要和人们对健康的重视程度有关，而未必和经济因素有太直接的联系，这样的话经济因素就不是身体素质下降的原因。
