这次仍是没有限时,经验不足啊。
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."

批驳点:
1,对于两组患者的身体情况不了解。也许一组都是身强体壮的成人,另一组是老人和孩子。也许不服用抗生素,他们也可以迅速恢复。
2,两组的医生不是同一个人,两者的治疗方式可能不同。第一组医生是sports medicine专业,很可能在治疗护理上做得更好。
3,对于抗生素是否有不良反应,还没有做出合理的实验。没有告知价格
In this argument, the arguer concludes that all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment. To support his conclusion, the arguer cites the doctors' long suspicion of secondary infection's preventing some patients from healing quickly after severe muscle strain. In addition, he provides the result of a study conducted at two groups of patients which demonstrated that the group having antibiotics healed more quickly than the control group. However, this argument is fraught with vague and oversimplified assumptions.
In the first place, the arguer fails to provide any evidence of the health state of people of the two groups. It is quite possible that most of people in the first group are healthy adults, while people in the second one are the old with varieties of disease, which slow down the healing of their muscle strain. In that case, the first group would heal more quickly than the second one without having antibiotics.
Another flaw that weakens this argument is that the doctors taking care are not at the same level. The doctor of the first group is a specialist in sports medicine, so it is easy to assume that he might be more experienced and operated a better medical project, which fastened the healing of this group, than another doctor, a general physician.
More over, the arguer fails to take into account other possible reasons such as the side effects and the price of antibiotics. Supposing that the antibiotics are very expensive, it would not be well advised, even if taking that can fasten the recuperation of the patients.
To conclude, the argument is not persuasive as it stands. Before we accept this conclusion, the arguer must present more facts to demonstrate that the two groups had the same medical project with the only difference of whether taking antibiotics or not, and that people of the two groups have very similar health state, and that the side effects of the antibiotics are not serious, and that the price of the medicine is not very high.
