改到这里发现跟前面看过的那帖子同一个话题,但总觉得单凭攻击开头Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain. 推导出Therefore, all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment."这一过程总觉得有点奇怪,但也想不出问题在哪,看到此兄的辩驳,发现我一直觉得不对劲的问题就在这里
但是,我认为楼主在这个问题上显得有点固执。当然,argument的攻击顺序,要遵从一定的逻辑性为好,但楼主在这里引用的这个argument作为例子,是有些misleading的!不可能把实验的内容放掉的!
下面是我的分析:
"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“
没错,我们的重点是攻击结论。但实际上,这个argument有两个表示结论的句子:This hypothesis has now been proved by……和all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment。
对于第一个结论,作者凭什么认为了这个假设被证实了?注意,实验中根本没有直接提到secondary infection! 那怎么说证实了呢?实际上,这里蕴含的假设是,因为抗生素能够防止secondary infection,而服用了抗生素的病人康复得更快,所以,是secondary infection阻碍了病人的康复。这样,错误就很明显了:能说第一组人就没有发生二次感染,第二组人就有发生二次感染吗?服用了抗生素,并不能保证不会发生二次感染,同时,只服用了糖丸的,也可能没有发生二次感染。没有弄清楚这个问题,不论实验结果如何,这个假设都是不能被证明的。
第二个:所有有肌肉损伤的病人都应该采用抗生素作为治疗。
那我们就要看作者是怎么推出这一结论的:由于在实验中,第一组采取了抗生素治疗,而第二组只用了糖丸,结果第一组恢复时间明显缩短,而第二组没有。所以,作者才会在结论中认为,要[采取抗生素]作为治疗。
显然,这里他的致命伤在于抗生素的问题。该实验是否真的证明抗生素有效?(医生不同,患者不同,这些都是我们驳论的角度)即使确实是抗生素造成了第一组病人的康复时间缩短,是否可以推广到所有病人?
从以上两个结论的分析,我们可以看出,这篇argument的所有焦点,都集中在那个实验上。而首句和末句之间,似乎是有暗含联系,但也完全可以孤立开来看。因为它们实际上都是通过中间部分的实验得出的结论。楼主强调“重点”,这才是重点啊!而开头和结尾之间的暗含联系,如果要说的话,也只有通过中间的实验才能说清楚。(这里就是我所关注的问题,毕竟,作者是靠这些实验来证明他的推论,而我们就是要反驳这种推理,从实验推出结果的过程)
综上所述,不能同意搂主的观点。首先是楼主关于“前提”和“结论”的判断不对,其次,some, severe这些措辞上的差异,和文中费大量笔墨去解释的实验过程中包含的错误以及从实验过程推出结论的逻辑错误,相比起来,哪个更是“细枝末节”呢?
毕竟,从出题者的角度出发,你想,他不会费了半天劲编出两个漏洞百出的实验,却希望你只抓住开头那么一个纯粹是引出性质的句子大肆发挥吧?
空口无凭,还是得靠题目出现的问题来攻击啊。而那些问题就是出现在实验之中,作者为什么推出那样的结论,是因为实验而推导出来的。也就是说,论据到论点,论据还是不能忽略的。AWINTRO指出论据中的(百分比啊什么的,就类似于此题中的实验,不是白给的,要反驳的是从论据推理出结果的过程,过程啊)感觉楼主忽略了过程。

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.
由实验推出所有的肌肉损伤者都需要服用抗生素
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.
攻击两组医生不同,其治疗方案啊什么的也许不同,还有治疗条件等之类
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.
怀疑两组患者是否有其他的病症(个人觉得攻击论据本身没有什么意义,应该论证的是推论的荒谬)
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.
两组的患者肌肉损伤程度不同,推出其治疗方案不同,可能不需要抗生素,伤势轻的患者可以较快地恢复。(????作者并没有提到此点,是推测吗,扯远了吧,重点是攻击如何推出抗生素对肌肉损伤治疗有效的荒谬推理,而不是攻击样本中如何如何)
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. |
