　　难易程度：★★★★

　　题目题材：保健

　　gre argument 142题目：

　　The article entitled &aposEating Iron&apos in last month&aposs issue of Eating for Health reported that a recent study(1) found a correlation(2) 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(3) 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(4,5).

　　提纲：

　　(1)The reliability of the result of the study is open to doubt.

　　(2)Merely a correlation between high levels of iron in the diet does not necessarily indicate a causal relationship between them.

　　(3)The author fails to provide evidence to substantiate the causal relationship between eating much red meat and heart disease.

　　(4)The author unfairly assumes that all people who have risk of heart disease would necessarily eating large amounts of red meat.

　　(5)High iron levels in the diet may result from many other factors, not only from red meat.

　　注：题目中括号里的数字表明这句话体现的是提纲中第几号缺陷。

　　无论是gre issue还是gre argument，考生都应该养成写提纲的习惯。这种提纲式的gre写作练习可以帮助考生锻炼写作的逻辑性，而gre写作高分最重要的得分依据就是作文的逻辑性要强。
