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.
五問(wèn):
(1)本段的第一句“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”是醫(yī)學(xué)專(zhuān)家的觀點(diǎn),并非本文的觀點(diǎn),屬于事實(shí),并不值得被反駁(盡管醫(yī)學(xué)專(zhuān)家的論述有誤——對(duì)比的對(duì)象不穩(wěn)定:不是使用同一個(gè)體質(zhì)測(cè)試標(biāo)準(zhǔn)來(lái)判定)?!皁verall fitness levels are highest in regions of Corpora where levels of computer ownership are also highest”和“this year's unusually low expenditures on fitness-related products and services, the recent decline in the economy”也是事實(shí)。同學(xué)們應(yīng)該注意:“the recent decline in the economy is most likely the cause, and fitness levels will improve when the economy does”才是結(jié)論,值得反駁嗎?
(2)影響個(gè)人健康的因素有哪些?過(guò)度使用電腦是不是這些因素中的一個(gè)?除此之外,你還能羅列其他一些可能的因素嗎?比如:抽煙喝酒、不良的生活習(xí)慣、年齡、職業(yè)等。
(3)你能否提供一種可能性來(lái)解釋為什么在電腦使用率較高的地區(qū),人們的身體狀況反而更好?是否可能這些地區(qū)的人格外年輕?是否可能這些地區(qū)的人都受過(guò)良好的教育,更加懂得如何保養(yǎng)自己的身體?
(4)我們能否簡(jiǎn)單地認(rèn)為在健康產(chǎn)品上的花費(fèi)是決定身體健康狀況的唯一因素?
(5)經(jīng)濟(jì)增長(zhǎng)與人們?cè)诮】捣矫娴幕ㄙM(fèi)一定是成正比的嗎?你能舉出反例嗎?例如:人們并沒(méi)有把錢(qián)花在健康產(chǎn)品和服務(wù)上。
