Based on dieticians’ knowledge, a scientific discovery, as well as a related common sense, the article infers that athletic activity participants could gain endurance and, in turn, win more games due to the vitamin N and fibrous supplement. However, the author’s assertion is based on groundless reasoning and therefore unconvincing.
To start with, the arguer assumes that the increase of professional athletes’ endurance, which is learned by the dieticians, is a result of the nuts they eat. Yet, the mere fact that professional athletes eating lots of nuts have more endurance hardly suffices to infer any cause-and-effect relationship between them. Without better evidence of what else have the professional athletes eaten, it is just as likely that some other food contributes to the increasing endurance, rather than the nuts.【NUTS的可替代性】
Moreover, the author invalidly uses the research discovery. First, he mistakenly equals the objectives who are frequently engaged in heavy physical activities with athletes. Probably, the combination of vitamin N and fiber could only benefit the physical workers, and even have negative effect for the athletes. Second, the arguer takes it for granted that the boost in the research is exactly improving endurance, which is problematic. It is possible that the respondents in the research became stronger, but not necessarily gained endurance. 【研究:NUTS的副作用与效用】
Even if the author’s understanding about the dietician’s knowledge and the research is correct, he proposes to take vitamin N along with the fiber, which is conflicted with the combination of the two elements mentioned in the research. Unless provides persuasive evidence that taking the two elements separately has the same effect as taking the combination, the author cannot convince me to believe his assertion.【两者与结合物的区别】
Finally, the article unjustifiably extends having more endurance to winning more games. Various factors are attributable to the athletic success, such as the burst of strength, the physiological state, and the physical healthiness. If the athlete gets severely sick, endurance cannot guarantee his success as well. 【体育比赛中的取胜因素】
In sum, the argument relies on series of indefensible reasoning. To strengthen the argument, the author should provide better evidence of more endurance of the professional athletes resulting from nuts, detailed information of the research, the same effect between taking the vitamin N and fiber separately and taking the combination, and the necessity of endurance’s leading role in an athlete’s success.
