In this article, the writer induces two results: first, he believes that using computers is not causation to less physically fit; second, he declaims that the recent decline in the economy causes low expenditures on fitness-related products and services, and fitness levels will improve with the economy. (我觉得否定电脑不是主要原因,是为了证明经济衰退导致健康下降)However, I find several flaws in this article which could not let me agree with the writer.
At the beginning, the writer does not provide persuasive evidences support the conclusion that using computers is not the causation of citizens' less physically fit. The writer cites an example that overall fitness levels are highest in regions of Corpora where levels of computer ownership are also highest, which help him induce such a conclusion. Nevertheless, he does not mention about the using computers levels in these regions. It is possible that there are a lot of industries making or selling computers, which preserve great number of computers in these regions, but never using at all. Even if levels of using computer are also highest in these regions, it is also probable that computer users in regions have other methods to ameliorate their fitness, as attaching importance to physical exercises at their spare time.
Secondly, no evidence proves that the recent decline in the economy is one reason to decrease fitness levels, which induces low expenditures on fitness-related products and services. At first, I could not be persuaded that low expenditures on fitness-related products and services cause low levels of fitness. Perhaps the most popular sports are outdoor exercises recently, such as running in road, swimming in sea or climbing mountains. Fitness-related products and services are not as attracted as before. Then, the writer does not provide clear relationship between economy decline and low expenditures on fitness-related products and services. The writer should provide persuasive data about the decline of fitness-related products and services. Even he should give compared data about other industries' situations in the economy declining.
Thirdly, perhaps there are some others reasons which cause levels of fitness declining in the last few years. It is possible that electric radiation from using machines causing eyes hurt or muscles sickness. It is also probable that the circumstances of living become more and more terrible to induce illness. For example, air pollution will cause pulmonary diseases and water pollution will induce tummy bug. Or perhaps people change their dietetic habits which are unscientific and easily to get sickness. I give snack culture as an instance. With the development of snack culture, McDonald’s has been to a worldwide company. A lot of people like food of McDonald’s, especially children. However, some children get fat sick because of excess eating of snack which has high calorie, such as fried chicken and potato.
(这段分析思路满开阔的,反例找得很好)
In summary, the argument lacks some convincing evidences to support the writer's conclusion. In order to prove his conclusion is proper, the writer should analyze clearly between the factors he mentioned.
总的来说说理不错,逻辑层次感很好!
只是好像少分析了一条:fitness levels will improve with the economy.
