TOPIC: ARGUMENT51 - The following appeared in a medical newsletter.
"Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain. This hypothesis has now been proved by preliminary results of a study of two groups of patients. The first group of patients, all being treated for muscle injuries by Dr. Newland, a doctor who specializes in sports medicine, took antibiotics regularly throughout their treatment. Their recuperation time was, on average, 40 percent quicker than typically expected. Patients in the second group, all being treated by Dr. Alton, a general physician, were given sugar pills, although the patients believed they were taking antibiotics. Their average recuperation time was not significantly reduced. Therefore, all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment."

根据昨天写的很模板的修改而来,今天看了一篇神帖以及神作若干,开始反省自己以前的Argument模式是不是错了。苦改之后贴在这里,希望大家能够就逻辑语言结构思想等各个方面提一些意见。
为方便大家修改,现将攻击点和与模板的异同写一下。
攻击点:
1. 研究结果不可靠。(没有控制变量,医生不同,两组病人的身体情况可能不同)
2. 错误的因果关系(未必是抗生素使治愈时间变短)
3. 结论的错误推广(未提及两组病人的代表性和普遍性,不能随意推广;同时病人身体状况不同,可能吃了抗生素有害处)
与模板的异同:
1. 由于是前模板文章修改而来,大致沿袭了经典的模板结构。
2. 不同之初在于开头的时候不再超简洁或者是寻找逻辑链,而是直接指出作者的错误的assumption。然后下文分段逐一展开。
3. 另外文章中间我将XDF的模板句清扫了一下,留下的句子基本上都还是比较舒服的,起码比较像人话。
4. 精简了结尾
The suggestion that all patients who are diagnosed with muscle strain should take antibiotics in order to fasten their healing process is not persuasive. The author’s argument is merely based on a study and he assumes that: the result of the study is reliable; it was antibiotics that led to the disparity between healing times; the measure recommended is suitable for every patient. These erroneous assumptions will be fully analyzed as follows.
Initially, the method adopted in the study is not reasonable and thereby the result of the study might not be reliable. Foremost, each group of patients has been treated by different doctors, which weakens the credibility of the study result. The author cannot ensure that efficacy of the two doctors would be the same on the same patient, and therefore he cannot eliminate the possibility that it was the professional abilities of doctors that resulted in the final discrepancy. Perhaps Dr. Newland was more experienced in treating patients in muscle injuries and it was his professional skills to shorten the healing time. In a more detailed way, maybe he diagnosed the situation of patients more accurately and treated in a more effective way than Dr. Alton did; or perhaps other indispensable medicine Dr. Newland offered his patients was better than that offered by Dr. Alton. Secondly, the physical conditions of patients in each group are unknown. Similarly, we cannot guarantee that it was antibiotics that actually work. Perhaps the physical conditions of patients in the second group were worse than that of patients in the first group; or perhaps the muscle strain of the patients in the latter group was less serious than that of patients in the former group. Either of the two likelihoods may cause the deviation of the recuperation time. In sum, it is far from enough to announce that the result of the study is trustworthy.
Moreover, even if the measures taken by two doctors as well as the physical conditions of two groups of patients were similar, the author unfairly assumes that antibiotics were attributable to the reduced recuperation time in first group. Lacking data to prove the direct correlation between antibiotics and muscle strain, the author too hastily draws the conclusion that antibiotics contributed to the shorter recuperation time. There might be other factors that determine the healing time. For example, sugar pills may have posed negative effects on the treatment of muscle strain, bringing about a longer recuperation time for the second group. In short, the author has to provide more evidence to successfully establish this causal relationship.
Finally, even if we admit that antibiotics are indeed the reason for reduced recuperation time for the second group, the author cannot confidently conclude that this measure should be recommended to all patients. First of all, the author fails to provide information about the patients in the study and thereby it remains a question whether those patients are representative to all the other patients. Perhaps those patients contain unique chemicals in the body which enable antibiotics to fasten the healing process in the study while all other patients might not. What's more, not all the patients should be treated with antibiotics since the mass use of antibiotics may bring about certain serious consequences. Perhaps some patients are allergic to antibiotics and thus antibiotics are not suitable for them; or perhaps large quantities of antibiotics will cause certain physical problems and should be avoided. After all, the author has to provide more proof to spread the conclusion to all the patients.
In conclusion, there lies many flaws in the study and therefore the advice suggested by the author might not be effective to all the patients. |
