argument160
我的第一篇argument,希望版主提建议
argument160题目:As people grow older, an enzyme known as PEP increasingly breaks down the neuropeptide chemicals involved in learning and memory. But now, researchers have found compounds that prevent PEP from breaking neuropeptides apart. In cases, these compounds almoost completely restored lost memory in rats. The use of these compounds should be extended to students who have poor memory and difficulty in concentrating and therefore serious problems in school performance. Science finally has a solution for problems neither parents nor teachers could solve.
作文:
In this argument, the arguer concludes the compounds, which can prevent PEP from breaking, should be extended to students to help them have better performance by having better memory and concentration. To substantiate the conclusion, the arguer cites tests that those compounds are effective in restoring lost memory in rats. A careful examination will reveal how groundless the conclusion is.
To begin with, the arguer bases on the assumption that the compounds used in rats can also be used on human beings. Yet the arguer fails to give any evidence on this crucial assumption. It is equally impossible that the impressive effect in rats wouldn’t suffice to ensure similar effect in human, while some factors, such as the difference in neurone, gene structure, that might have great influence on how the compounds react. Without considering and ruling out these possibilities , the arguer’s conclusion might lead to false analogy, let alone the recommendation of extended use on students.
Even if, the compounds can be effective in prevent PEP from breaking when people grow older, it is not necessarily that the compounds can have the same effect on students, who are on their youthful age. Scant evidences show me the compounds are useful to both the old and the young. Without considering that the old might have poor vulnerability to health problem, or less brainwork, or other factors that might contribute to the problem of PEP breaking, the arguer unfairly enlarges the function of the compounds, which renders it unconvincing as it stands.
Even if I were to concede that the compounds can be extended to students, which help prevent PEP from preventing in order to improve memory, the arguer fails to establish a correletion between the compounds and better concentration. For there are no evidence showing that the compounds have anything to do with concentrating, the arguer’s conclusion is weaken by such rough assumption.
Last but not least, the arguer’s recommendation, that the compounds can eventually help students perform better in school, is based on the assumption that better memory and concentration are the only factors be responsible for good performance. However, the arguer ingores a myriad of revelant factors that might account for good performance, such as creativity, clear goals, hard-work etc. without comprehensive understanding how to achieve good performance, I have enough reason to doubt the conclusion of arguer.
In sum, the arguer’s conclusion is logically flawed in many respects. Rather than rely on the questionable assumption, the arguer should provide more evidence that the compounds have the same effort on students as that on rats. To strenghten the argument, the arguer might have to show me the compounds also have influence on better concentration. I would also need to know the correlation between good performance in school and better memory or concentration. |
