48. The following appeared in a newspaper article published in the country of Corpora.

"Twenty years ago, one half of all citizens in Corpora met the standards for adequate physical fitness as then defined by the national advisory board on physical fitness. Today, the board says that only one quarter of all citizens are adequately fit and suggests that spending too much time using computers may be the reason. But 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."

20年前，Corpora的市民有一半都达到了那时由国家健身顾问委员会所定义的充分的健康标准。今天，委员会指出所有市民只有四分之一的市民足够健康，并指出长时间的使用电脑可能是原因。但是由于在Corpora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。

 

1.现在只有1/4的市民足够健康，但是有可能是因为现在的健康标准远远高于20年前健康的标准造成的，而实际上市民的健康水平已经提高了很多了。

2.电脑拥有量最高的地区不代表使用电脑的时间长，有可能人们每天只是用1-2个小时。

3.用于健身产品和服务的花费很低，并不能说明经济的衰退，有可能是因为把更多的精力和金钱用于工作和学习上。

4.即便经济的衰退时最可能的原因，当经济复苏后，健康水平也不一定随之提高，人们不一定会吧金钱和时间用于健身服务，而是用于更多的购物，旅游等等。
