题目: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."
In the argument, the author cites a study that two group of patients were treated for muscle injuries by taking antibiotics and sugar pills, the results is antibiotics group recuperated quicker than the other group without taking that medicine. In that case, the author infers that antibiotics have effect on treating secondary infections which prevent healing quickly after severe muscle strain. Hence, the author concludes antibiotics could make muscle strain patients heal quickly, therefore he or she recommends that antibiotics should be taken by all patients who are diagnosed with muscle train. However, the argument suffers from a series of poor assumptions, which render it unpersuasive.
To begin with, the author cities the study as the evidence to prove taking antibiotic is an effective means of treating secondary infection. However, the author provides no evidence that whether patients who involved the study have suffered secondary infection after muscle strain. If not, the result that antibiotics could shorten recuperation time prove nothing about the hypothesis that long recuperation time of muscle strain patients causes by secondary infection.
Besides, even assuming all the patients have secondary infections, the study still appears to be weakened by its questionable method and statistics. As we know, for an experiment to be accurate, it must be controlled, with a balance between the experimental and the control group, which means all the factors that potentially affect the results, should remain constant during the experiment. In the above study, unfortunately, three factors may impact on the results. First of all, there is no information about the patients involved in the study such as ages, backgrounds, physical condition and the severity of injury. It is possible that patients are younger, stronger, or injured more serious in the first group than those in the other group. Secondly, the author fails to consider the fact that doctors play a significant role throughout the treatment. In generally speaking, Dr. Newland who specializes in sports medicine have more experiment and professional skill in treating muscle than a general physician Dr. Alton. In this case, it is entirely possible the first group recuperated faster than the other group without antibiotics due to the treatment from sports medicine specialist. Thirdly, the sugar pills given to the second group is open to doubt. Perhaps sugar pills have side effect on secondary so that made the second group recuperated slower. In short, without ruling out all other possible factors may influence the result, the study cannot be a evidence to prove the hypotheses.
Finally, even if the author can substantiate all of the foregoing assumptions, the author’s assertion that all the patients diagnosed with muscle strain should take antibiotics is unwarranted. Experience tells me, a part of people are allergic to antibiotics due to their physical constitution and genetic predisposition or they are in a special period such as pregnancy. Taking antibiotics mistakenly will cause uncomfortable like dizziness and shock. For that matter, the author’s conclusion is unjustifiable.
In sum, the argument, while it seems logical at first, has several flaws as discussed above. The author should provide better evidence about the information of patients, doctors and sugar pills to ensure the reliable of the study as evidence of the assumption. Furthermore, before making recommendation to patients, the author should make sure they do not have an allergy to antibiotics to guarantee their health.
这是自己先改过的,我很纠结第三段要不要分开,都是说的实验的问题, 但太长了
给点建议吧 |
