GRE作文Argument的抄袭问题~

其实Argument就是模板类作文，开头，中间，结尾，整体都可以用模板的。
老美那个雷同探测程序只考察Issue，对A没有探测的。

题中的意思是铁摄入过高会导致心脏病，而也有研究表明吃大量牛羊肉也与心脏病有联系，题中给出的解释是牛羊肉导致心脏病的原因是牛羊肉中含铁高。就和之前你的理解一样。

范文的最后一段是质疑这个结论，即使牛羊肉导致心脏病，铁摄入过高也会导致心脏病，但这两者之间未必是有联系的，吃牛羊肉的人也可能吃了很多其他含铁很高的食物，并不能说明吃牛羊肉导致心脏病的原因就是因为铁摄入过高。

事实上这个一段给出的理由有些牵强，你可以自己想一些理由，比如牛羊肉含铁量多少，是否都被吸收等。

北美范文并不是十全十美的，有些地方也有点不合理，因此提纲都要自己列过，而北美范文值得参考的是文章的结构和语言表达。

"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 this argument, the arguer concludes that all patients suffering from muscle strain would be well advised to take antibiotics as part of their treatment. To strengthen this conclustion, the arguer cites a study of two groups of patients of muscle strain. Also the arguer provides the statistics indicating that patients taking antibiotics recovered more quickly than those taking sugar pills. At frist glance, the argument might be somewhat reasonable, however close scruntiny reveals that it contains several logical flaws and is therefore unpersuasive.
First of all, there's a false causal relationship between the hypothesis and the study. Although the hypothesis and the study are both related to muscle strain, the former claims that secondary infections could prevent patients from healing quickly while the latter investigates the active effect of antibiotics on those patients.
Second, the arguer fails to consider the possible differences between those two groups of patients, thus causes an unconvincing comparison. For example, perhaps patients of the second group primarily consist of young people while the other group of old people on the contrary. Common sense informs me that the former recovers much faster than the latter in the case of muscle strain because of hermone secretion and metabolism. Without ruling out all the other possibilities, I cannot accept the arguer's contrast of those two groups.
Third, even assuming that the study of patients from those two groups is based on the identical background, the arguer unfairly indicates a causal relation between the antibiotics and the shortend recuperation time for the first group. However, there could be some other factors such as the special rehabilitation training or some unique substance from food, only the combined application of which will lead to a quick recovery. Similarly, the potential efficacy of sugar pills could also be counteracted by other medicine.
Finally, even if the shortened recuperation time is attributalbe to the use of antibiotics for patients of the first group, the arguer overlooks the negative effects that antibiotics would bring to those patients. For instance, perhaps antibiotics might cause dizziness and influence the digestive function of patients. Or perhaps antibiotics would kill immune cells, therefore patients are more vulnerable to disease during the treatment. Without accounting for these possiblities, the arguer cannot convince me that the use of the antibiotics is a benefical recommendation.
