Outline:
1. 没有铁元素导致心藏病的证据
2。没有证据说是红肉里的铁元素导致心藏病
3。也许有未知的共同原因引起红肉吃得多，也引起心脏病。那么铁元素和心脏病就没有因果联系了。

TOPIC: ARGUMENT142 - 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.

In this argument, the speaker concludes that the correlation between heart disease and red meat attributes to the correlation bewteen the high iron levels in diet and heart disease. However, a close scrutiny reveals that the underlying logical flaws invalidate this conclusion.

Firstly, there is no evidence suggested that it is the high level of iron in the diet causes an increased risk of heart disease. Though a non-academic article is cited to suggest the correlation between high level of iron in the diet and an increast risk of heart disease, no convincing evidence substantiates that the it is the iron causes heart disease. It is possible that the other element in the diet, which accompnies with high iron level, cause the increased risk.

Secondly, there is no evidence implies that it is the iron in red meat directly relate to the heart disease. The arguer mentions the observed link between large amounts of red meat in the diet and hear disease, along with the abundance of iron in meat to set up the claimed correlation between iron in red meat and heart disease. However, the arguer overlooks the possibility that the iron from red meat obsored by people can be low event iron is high in red meat and red meat is eaten a lot by heart disease patients, due to the difficulty to obsored neutrition in meat or other else reasons.

Finally, the arguer omits the possiblity that there is a third reason, rather than red meat or iron, that causes hear diease. There may be a element that lead potential heart disease patients tend to consume more red meat, and probably hence iron. In this case, the correlation between iron level and hear disease would be independent of the correltion between red meat and heart disease.

In sum, several logically necessary elements are neglected in this argument. And arbitrary generalization and extension of correlation are drawn. All together, it leads the conclusion lacks of scientific capability to convince.

In this argument, the speaker concludes that the correlation between heart disease and red meat attributes to the correlation bewteen (between) the high iron levels in diet and heart disease. However, a close scrutiny reveals that the underlying logical flaws invalidate this conclusion.

Firstly, there is no evidence suggested that it is the high level of iron in the diet causes an increased risk of heart disease. Though a non-academic article is cited to suggest the correlation between high level of iron in the diet and an increast (increasing) risk of heart disease, no convincing evidence substantiates that the (去掉) it is the iron (加上that形成强调句) causes heart disease. It is possible that the other element (elements 因为后面主句是cause) in the diet, which accompnies (??) with high iron level, cause the increased risk.

Secondly, there is no evidence implies that it is the iron in red meat directly relate to the heart disease. (与第一段开头的形式一样，建议换一种表达方式) The arguer mentions the observed link between large amounts of red meat in the diet and hear disease, along with the abundance of iron in meat to set up the claimed correlation between iron in red meat and heart disease. However, the arguer overlooks the possibility that the iron from red meat obsored (absorbed) by people can be low event iron (这句话感觉用的牵强) is high in red meat and red meat is eaten a lot by heart disease patients, due to the difficulty to obsored neutrition in meat or other else reasons.

攻击点找的没问题，但是攻击的不是很透彻，感觉没说透。

Finally, the arguer omits the possiblity (possibility) that there is a third reason, rather than red meat or iron, that causes hear diease. (heart disease) There may be a element that lead potential heart disease patients tend to consume more red meat, and probably hence iron (hence 后面一般跟句子) . In this case, the correlation between iron level and hear disease would be independent of the correltion between red meat and heart disease.In sum, several logically necessary elements are neglected in this argument. And arbitrary generalization and extension of correlation are drawn. All together, it leads the conclusion lacks of scientific capability to convince.
