Even if one accepts the survey results, the argument remains questionable. 作了一下让步，开始攻击因果关系不成立。The argument assumes that the correlation between the use of SMILEBRIGHT and capped teeth means that SMILE BRIGHT causes the need for capped teeth. 这里就复述题目了，同时也是立起靶子，等待攻击。 But the argument fails to provide sufficient evidence to support the conclusion.指出没有证据显示有因果关系。先打拆开关系。
In addition, the argument fails to consider the possibility that people who already have capped teeth might prefer SMILEBRIGHT as a toothpaste because it works better on capped teeth.这里举出了个他因，甚至有点想逆转原来的因果关系的意思，从而使已经打拆开的因果关系分的更加清楚。
Finally, the argument's author fails to rule out alternative explanations.这里继续打拆上一段打开的因果关系，提出了他因，就像往伤口上撒一把盐。打个比方，女生家长为了不让女儿和一个男生在一起，就先把他两个给隔离起来，然后最狠的就是，给那个男生找一个巨棒巨棒的新女朋友。For instance, people who brush their teeth more than twice a day might be those who are prone to the need to have their teeth capped. 举出第一种可能性。Weak结论(一天两次更易带牙套)。 It might also be the case that starting with SMILEBRIGHT early in life damages the teeth so that capped teeth will be needed later.
举出第二种可能性。Strengthen原结论(早用早带牙套)的.It also might be the case that SMILEBRIGHT users tend to be the kind of people who are excessively concerned with the appearance of their teeth, perhaps theyre actors, and so are the kind of people who might, sooner or later, want to have their teeth capped anyway.举出第三种可能。论证方法为加条件后讨论，讨论采用三段式。来源：考试大的美女编辑们
In conclusion, the argument, while it seems logocal at first, has several flaws as discussed above. 这句话很经典，摸版性很强。 The argument could be improved by providing evidence that the correlation is indeed a causal relationship -- that using the toothpaste actually causes the need for capped teeth.
给出第一条建议是针对没有因果关系的那段的。It could be further improved by ruling out alternative explanations for the supposed causal relationship.给出的第二条建议是针对因果关系中提供他因的那段。总的来看，这里的提建议的方式以及位置都和作文地带和北美范文很像。最后，我们发现这文章所指出的逻辑错误都是大错误，那种脊梁骨似的错误，而对于小错误，比如他们report则不予讨论，看得出来，官方的意思是，无论什么文章，都最优先挑核心逻辑链中的重点错误，小错误能挑出来更好，但没有也没关系，前提是大错误都挑出来了并且论证充分。本文与前面的文章的差别之处就在于，很难找到文章的中心思想，只是罗列了错误并独立的分析，过于平淡，而没有对于文章的核心错误的把握。
COMMENTARY
This outstanding response begins by announcing that the argument "contains several facets that are questionable."
The author then develops the critique around three main points:
-- the reliability and generalizability of the survey results are open to question;
-- the argument assumes that a correlation amounts to a causal relationship; and英语作文
