依然感谢帮我改作文的同学, 又让你等了这么长时间呀~
(忽然发现上面那句话打了逗号后居然习惯性地加了一个空格,看来已经形成条件反射了ToT)
还是麻烦看一下吧~使劲拍砖使劲拍砖~
TOPIC: ARGUMENT91 - The following appeared in an article in Supplements Today.
"Dieticians have long known that professional athletes who eat a lot of nuts have higher levels of endurance than those who do not. Researchers have recently discovered that the particular combination of vitamin N and fiber found in some nuts provides a boost for those who participate in strenuous physical activities daily. Both vitamin N and fiber supplements are easily synthesized and widely available. As a result, all those who participate in athletic activities will be able to increase their endurance and win more games by taking vitamin N along with a fiber supplement."

The argument is well-presented, but not thoroughly well-reasoned. By noting that athletes who eat lots of nuts, which contain a particular combination of vitamin N and fiber, would have more endurance than those who do not, the author suggest athletes take vitamin N along with fiber supplement to win more games. However, before examining alternative possibilities, it is too hasty to draw any conclusion.
To begin with, the author rests his argument on the assumption that eating a lot of nuts is the cause of having higher level of endurance. Yet the argument is unacceptable if there is no compelling evidence to support the connection between eating a lot of nuts and having higher levels of endurance. It may be other things the athletes eat or drink like protein powder solution that enables them a better endurance. The argument could be more convincing if two groups of athletes are selected, one group eats a lot of nuts daily and another group do not, keeping other conditions identical, and watch their levels of endurance over time.
Moreover, the author falsely makes use of the research result. On one hand, the constitution of athletes and heavy physical activity participants could be different, and the effect of eating a lot of nuts on those who participant in strenuous physical activities daily does not necessarily apply on athletes, who may be engaged in games that require more techniques and do not ask for heavy physical activities. On the other hand, the research result does not mention that the boost provided by nuts is the enhancement of endurance, and could totally possible be an improvement of reaction or the sense of equilibrium.
The argument also confuses the combination of vitamin N and fiber with separate vitamin N and fiber supplement. The combination of different molecules could have properties different to those of the molecules that form it. For example, to quench thirst, one may drink water, a combination of hydrogen and oxygen, but one may never succeed quenching thirst by "drinking" hydrogen and oxygen. Analogously, taking vitamin N along with a fiber supplement would more likely have other effects but not increasing endurance.
Finally, even if nuts are the key to providing higher levels of endurance, not all athletes would benefit from eating it to win more games. There are many athletic activities like table tennis that require techniques, skating that asks for good sense of equilibrium, weight lifting that depends mainly on force, and a high level of endurance would help little in any of these games. As a consequence, even if eating nuts can improve endurance, few could benefit from it to win more games.
To sum up, the author gives a seemingly promising suggestion to winning more athletic activities by eating a lot of nuts. But before the alternatives mentioned above are ruled out, and effective combination of vitamin N and fiber are synthesized to use for athletes of games that mainly depends on endurance, hardly could anyone be benefited.
