According to a group volunteers' report of the positive effect of Luxess facial cream, the arguer claimed that this product remarkably improve the condition of facial skin. How ever, scrutiny on the argument would reveal a series of fallacies in the reasoning line, concerning the sampling process and casual relation ship between the product and effects.
First of all, a convincing experiment should be well controlled in the participants, a survey and selection of participants should be well organized;这个TS写的别别扭扭的 ^_^ however the speaker of Luxess provide no further information about them, such as their ages, genders, or basic conditions of skin face, thus the reports of Luxess cream would not convincing enough. For example, the young boys or girls skin were more vital and easy to nurture, while the skin of middle ages or old people were already matured and the replacement of the skin cell was is slowing down even stopped, the product will show great difference between these two group of people. Thus, a product effective to youth would not necessarily be effective to the old people as the same.
Even if the sampling of the experiment have been well controlled, include various people, youth and olds, male and female, the improvement of their skin condition could not inevitably ascribed to the using of Luxess, since the speaker severely failed to rule out other factors which could also improve the participants skin conditions, for example in point, the mild soap. As a result, the customers could naturally doubt that whether the improvement was caused by using Luxess, or simply by the mild soap? Consequently, the acclamation for Luxess' effect would be severely undermined. 这一段写的不错,让步,观点,举例,结论,一气呵成
Last but not the least, according to the speaker for Luxess, the participants in this experiment simply "reported" marked improvement in the way their "looked and felt", but not a persuasive qualification from authentic medical of facial health organization. Thus the test-takers personal feeling may be not precise and could be remarkably influenced by their psychological factors. In addition, a safe facial product should be tested carefully and prudently to be qualified as non-toxic contained, from this point, one month test was far from enough. 这一段和第二段关系比较密切,都是有关participants的,两个段落挨着比较好。
In sum, the speaker fail to provide the basic profiles of participants, neither rule out other factors which may be responsible for the result, thus the conclusion of Luxess was open to doubt
另外,测试时间短这个问题没有批驳,这个flaw是很经典的。
还有,side effects,也是关于推荐产品这类题目里都可以提一下
