经过数个月对Argument一心一意的钻研,并研读了书多本GRE作文书及寄托上的帖子后,最近写了这篇A51,自己修改了多次,请广大G友多多指教~~小女感激不尽,希望自己数月的努力没有白费。。。。
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."
Grounding on a study of two groups of patients, the author attributes quick recuperation time most to the intake of antibiotics, and therefore recommends all patients with muscle strain should take antibiotics to convalesce quickly. The argument, while seems logical at first glance, actually rests on several unsubstantiated assumptions.
At the beginning, the author assumes that the research results about these two groups of patients who suffered from muscle injuries are reliable. Yet, the author provides insufficient evidence to support this assumption. The author must inform me that a large number of people are involved in this research and these two groups of patients are representative of all patients who were diagnosed with infections caused by muscle strain. Also, the soundness and scientificalness of the study must be substantiated to ensure the dependability of the conclusion. For example, whether these two groups of patients were cured under the same treatment condition, such as their hospitalization environments and dietary intake of each meal? Did they have the same kinds of exercises aside from taking medicine as part of their treatment? Otherwise, it is unwarranted to draw any conclusion about the effectiveness about antibiotics in face of such limited evidence.
Secondly, even assuming that the reliability of the study allows of no doubt, it is irrational to infer that antibiotics are the primary factors contributing to accelerate patients' recuperation time. The author ignores a host of other possible alternatives to the quick recovery rate. Perhaps since Dr.Newland specializes in sports medicine, he possesses better professional knowledge in terms of curing muscle strains which in most cases are caused by sports and owns more experience as to how to effectively treat patients. It is even possible that Dr.Newland is more responsible than Dr.Alton, and subsequently put more effort and time to take care of those patients. Or perhaps patients in the first group have stronger recovery ability to rehabilitate from muscle strain than those in the second group. They may still quickly recover even if they do not take any medicine. Without ruling out all other such factors, the author cannot justifiably conclude that antibiotics are beneficial to cure patients with muscle strain.
In addition, even if these two groups of patients are advised to take antibiotics for their treatment, it is nevertheless unfair to infer that all patients should adopt the same medical measures. How about those people who may be allergic to antibiotics and become severely sick after they take these kinds of drugs? And will antibiotics produce same effect on those patients who are suffered from the first infections with those that are diagnosed with the secondary infections after muscle strain? As a matter of fact, antibiotics may even exacerbate rather than cure illness for patients who are infected for the second time. As the same token, although antibiotics precipitate recuperation of infection after severe muscle strain, those medicines may not apply to all levels of muscle strains. Perhaps appropriate rest is enough for people only with light muscle injury.
Finally, the author cannot overlook the negative effects that antibiotics may bring to patients. It is possible that long-term intake of antibiotics will increase patients’ dependence on drugs and also lesson their resistance to all kinds of diseases. And it may also harm people’s certain organs and trigger other illness, like stomachache or hypertension.
In sum, the author’s recommendation about taking antibiotics for patients diagnosed with muscle strain is not well supported. To better convince me, the author must offer sufficient evidence to substantiate the reliability of research and establish a direct causal relationship between antibiotics and recuperation time. It is also necessary to rule out all the negative effects that antibiotics may bring.
