"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."

According to the preliminary result of a study of two groups of patients, the author comes to the conclusion that all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment. Although sound it seems, the argument is flawed in several aspects.

Primarily, maybe other factors other than the taking the antibiotics contributed the different effects of the two treatments in the study. The two groups of patients were treated by different doctors. Except for the antibiotics, there are many differences between the treatments - the doctors' skills, the treatment measures and the equipments the doctor used. Maybe, Dr. Newland has better skills, and the measures and equipments he used were more advanced. All of these advantages can explain why the recuperation time of Dr. Newland's patients was greatly reduced. In addition, the conditions of the patients in the two groups maybe different. Perhaps, the patients of the first group have less serious injuries than those of the latter group, leading the first group easily to recover.

Besides, the author ignores the negative effects of the antibiotics. Nearly all the medicines have more or less side effects. The author provides no evidence to prove the antibiotics is an exception. The author only mentions the patients' recuperation time, no informing us whether the patients in the first group had some new symptoms, such as headache, nausea, powerless and sleepy. Even if the patients did not have any new symptom, there is no guarantee that in the future they will not have any symptoms caused by the antibiotics. Perhaps, many patients have serious headache three months later. Lacking clinical experiment, the author can not assert that the antibiotics do not have negative effects, considering the safety of the patients.

Additionally, given that the antibiotics do not have any side effects and help patients with severe muscle strain recover, the author's proposal that all the patients with muscle strain should take antibiotics is unacceptable. The treatments of the patients with light muscle strain are not the same with those of the patients with severe muscle strain. Perhaps, without taking antibiotics, the patients with light muscle strain will still recover quickly and will not have the danger to get second diagnosed. If this is the case, it is not reasonable to advise those patients to take antibiotics, letting alone the high price of antibiotics.

In sum, the argument is not well reasoned. To strengthen it, the author must prove us that it is the antibiotics rather than other factors explain the difference between the recoveries of the two groups of patients. What is more, the author should prove the antibiotics have no side effects and all the patients with muscle strain need to take them.

Nearly all the medicines have more or less side effects既然这样说了的话，那么抗生素有副作用也是理所当然的了，又为何花一段来驳呢？

后两段逻辑不清楚。
很多逻辑错误作者只是点到而至，没有深入。比如：Perhaps, the patients of the first group have less serious injuries than those of the latter group, leading the first group easily to recover.
letting alone the high price of antibiotics.
语言不错。
