142 The article entitled 'Eating Iron' in last month's issue of Eating for Health reported that a recent study found a correlation between high levels of iron in the diet and an increased risk of heart disease. Further, it is well established that there is a link between large amounts of red meat in the diet and heart disease, and red meat is high in iron. On the basis of the study and the well-established link between red meat and heart disease, we can conclude that the correlation between high iron levels and heart disease, then, is most probably a function of the correlation between red meat and heart disease.

论断:红肉和心脏病的关联很可能是含铁量高和心脏病的关联造成的。因为一个研究的成果以及已成立的红肉和心脏病之间的联系。这篇文章说最近的研究发现高含铁量的配餐与升高的心脏病危险有关联。而且饮食中大量的红肉成份和心脏病的联系是已确立的,红肉里的铁含量高。(unoxidated iron.calcium,heroin,rusty iron,compound)
•没有提供资料的前提:红肉与心脏病之间的联系,没数据,没研究,没调查。含量?食用方式?
•不一定成立的前提,即使红肉与心脏病的联系成立,没有资料证明红肉食用多的铁吸收就会多。有可能红肉的铁不容易被吸收的话。
•论据,研究结果不确切,高含铁量与心脏病之间的联系是怎样?铁对身体的影响有很多种,一定铁的摄入对身体是有好处的,非氧化铁,锈铁有区别。结论:红肉的含的铁是怎样的,不一定会是造成心脏病的。所以不能得出结论红肉与心脏病的联系不是其它因素造成。

1 无科学根据,太笼统
2 很棒! 心脏病他因引起
3 聪明!铁与心脏病无关,他因

主要攻击function这点
如果人们根本不吃红肉,那么红肉中含铁怎么会导致贴于心脏病关系呢??可能是其他含铁事物导致。
另外,本题没有考察病因。全篇在说correlation。所以不要用关系不等于因果这条。
注意:
well established是不用攻击的。
function是函数的意思。A is a function of B 指B得出A(即使我们把function理解成作用,结论是一样的:B是本质,A是现象)
本题根本没有推导原因:通篇都在谈CORRELATION而没有得出病因!因此不要写原题的因果关系不成立或相关推不出因果。原题根本没有因果嘛。
原题的逻辑是:study说明铁与病有关(可以无奈的做个庸俗攻击);well established的理论说明肉和病有关,且肉里铁多。得出:肉与病的关系--〉铁与病的关系。关键证伪这个“--〉”即function
由于两个论据实际上只是描述现象(关系)因此都没的攻击,只有结论可攻击。
关于下面两篇参考文章中的问题:
silentwings的错误:red meat引起心脏病------------> red meat 里面还有大量的铁 ------------------> 高铁引起心脏病。
原题没说引起。
happyman2000的错误:这是一个变态的句子,根据我们的常理,以上因果关系应当完全倒过来才说得通,所以,故意颠倒原因与结果。happyman2000似乎认为:铁是一种可能致病的元素,而红肉只是载体,因此应该是铁与病有关->肉与病有关。
但是本题恰是肉与病有关已经well established,不是故意颠倒因果(但这道题是故意难为我们的)。大家不要想当然。
他的攻击:直接攻击,1,铁不一定能引起心脏病;2,即使铁能引起心脏病,并不意味着含铁的红肉能引起心脏病。显然不对。
但是happyman的这句话是对的:上文最后一句话的理解应该就是铁与心脏病的关系是由红肉与心脏病的关系决定的,即红肉和心脏病有关系,所以铁才和心脏病有关系。
我们要说明这个function不成立 。方法:given铁与心脏病有关系,且红肉与心脏病也有关系,但如果人们不吃红肉而吃其他的高铁食物 (他因),那么,原题结论function就完蛋了。
另外:常见的攻击方法:肉里有其他致病物导致心脏病。似乎是无效的,因为不论怎么折腾病因,相关关系还是存在的!攻击无效。

析题:仔细读过,发现这道题有点绕,很多考生曾经有过这样的困惑:“我没有理解最后一句话的意思 is most probably a function of the correlation between red meat and heart disease.是说 high iron level 于 heart disease之间的关系 是 red meat 与 heart disease之间有关的结果 那作者到底是认为 high iron level 和 heart disease之间有没有关系阿?” 再读之下,我们会发现作者其实做了一个顺接推论:red meat引起心脏病------------> red meat 里面还有大量的铁 ------------------> 高铁引起心脏病,就是这么一个简单的推论过程,关键认清谁推出谁,就要在审题时注意到关键的这么看似不经意却被友好的ETS“重复两次”的短语“well established”,也就是说“大量红肉与心脏病之间一定有联系”是不容质疑的论据,即本题论据是不容批驳的,关键问题在于由论据推导出结论的时候犯了“Implicit causal claims”和“gratuitous assumptions”(详细逻辑谬误分类见后文 “七宗罪”),因而我们就可以以次展开攻击。很多来自网上的文章和提纲在本题上颠倒了推导对象,把“高铁引起心脏病”作为论据来推出“red meat引起心脏病”,结果导致文章失误。下面读者可通过以下范文检验一下该论证过程和思路:
(范文)
The correlation of the high irons level and heart disease the arguer trying to prove is not as perfect as he assumes. Although at first glance, his cause-and-effect analysis seems quite cogent, yet it can't stand much reexamination.
I agree to the well-established theory concerning the necessary relation between the large amount of red meat in people's diet and heart disease, but no other possibilities can be ruled out except for one of the ingredients-iron. It is obvious that the arguer constructs his building of conclusion on the basis of the conviction of the deleterious function stems from the iron. While not only a single iron does red meat contain, as we all know, many other components also have the influential role once being indigested into human body. For instance, some type of particular protein it might include, instead of the iron, is the substantial root of heart attack. So the arguer's peroration has no convincing power for this gratuitous assumption.
Moreover, even though his deduction does really derive from some passage of authoritative researches he has no opportunity to list below, the assertion about the high levels of iron related to the possibility of heart disease cannot be got through by merely so qualified the evidence exhibited here. According to the arguer's elicitation, we believe the red meat does contain large amount of iron, however, we might ask ourselves such questions enlightened by our common sense, "Does the amount of iron involved in red meat reach the dangerous level enough to lead to heart disease?" The answer we can't obtain through this short argument, thus directly make us doubt the whole fruits the arguer attained.
As it stands, the study reported on the published media Eating for Health is inevitable filled with some lethal logic fallacies, which finally weakens the cogency of the whole claims. To such a paramount and sensitive issue relative to people's health and life, scrutiny is not allowed to be neglected; and it is just for this point, I'm afraid, no people could ultimately abjure for eating red meat as a result of reading this ridiculous article.

No.1 再讨论一道argument超级难题,argument 142
142.The article entitled 'Eating Iron' in last month's issue of Eating for Health reported that a recent study found a correlation between high levels of iron in the diet and an increased risk of heart disease. Further, it is well established that there is a link between large amounts of red meat in the diet and heart disease, and red meat is high in iron. On the basis of the study and the well-established link between red meat and heart disease, we can conclude that the correlation between high iron levels and heart disease, then, is most probably a function of the correlation between red meat and heart disease.
这个题目的理解关键在于最后一句话,从字典中查到对function的一个解释,
Something closely related to another thing and dependent on it for its existence, value, or significance: 应变物与另一决定它的存在、价值或重要性的事物密切相关的事物。
例句:1,Growth is a function of nutrition.长身体是由营养决定的
2,X is a function of Y. X是Y的函数(即X的值由Y决定)。
3,A is a function of B. A由B决定。
根据这个解释,上文最后一句话的理解应该就是铁与心脏病的关系是由红肉与心脏病的关系决定的,即红肉和心脏病有关系,所以铁才和心脏病有关系。
这是一个变态的句子,根据我们的常理,以上因果关系应当完全倒过来才说得通,所以,故意颠倒原因与结果,可能就是一个主要的攻击点。但是,如果抓住这点进行攻击,就等于我们承认了铁能够引起心脏病,从而红肉也能引起心脏病,这就把后路堵死了,很难再找到第二个攻击点了。如果不对这点进行攻击,倒是可以凑上几段,但很明显忽略掉了最主要的问题,攻击变成了隔靴搔痒。
我都怀疑ETS是不是把这道题搞错了,如果最后一句话的因果关系颠倒一下,不就很好写吗?直接攻击,1,铁不一定能引起心脏病;2,即使铁能引起心脏病,并不意味着含铁的红肉能引起心脏病。有其他原因导致心脏病,有铁的吸收问题等等。
我看了几片流行的提纲和范文,基本上都是按照对题意错误的理解写的。大家看看,有何高见!
我的提纲:
1.研究是否科学,样本是否全面可靠.
2.研究只说铁含量过高与心脏病有关联,没说是因果关系.并不能得出结论.
3.就算铁多会有心脏病,但是红肉中的铁也一样么?也许不同物质中含的铁对人体的作用是不同的.
