在一本作文参考书上发现的范文,似乎在赞同argument中的观点,令见少识窄的我看后瞠目结舌。试问各位前辈,这样也可以?
Consisting of two “correlations,” this argument seems to me at first sight. But I find it reasonable when I relate it may own experience.
It is well established that iron, like calcium, is important for good health. And it is for that reason that some foods (some vegetables, for example) are especially valuable for their iron content, and children have been educated to eat enough such foods so as to take in enough iron. Under these circumstances, it is against our commonsense to say that “high levels of iron in the diet” can lead to "an increased risk of heart disease," found by a recent study and reported in the article entitled "Eating Iron" in last month's issue of Eating for Health.
To establish this correlation, you can either look for evidence provided by further research work, which can be rather costly, or find evidence in something that is "well established" in it. This argument is well reasoned because it is exactly based on such evidence? a second correlation, i.e., "the correlation between red meat and heart disease."
In turn, this second correlation has to be based on something that is also "well established." Well, we have it in the fact that "red meat is high in iron," which is "well established" according to this argument, and is evidenced by my own experience, as follows:
Growing up in a village, I remember how my folks used to make red meat. In those years, I remember, when there was a festival, especially when the Spring Festival was to be ahead, like all village folks, my mother would get extremely busy making good delicious foods. One favorite of mine was red meat. Since I liked it very much, I was curious about how it was made, and did find how: My mother would buy from the nearby drugstore a powdered, red substance, and mix it up with the meat. At that time, I did not know what that substance was. Later on I learned that it is a mineral of iron, which can be used medically, and can be used to give a lovely color to food, especially meat. Comparing this experience of mine, I find the statement that "red meat is high in iron" truly well established.
In this way, a correlation (the one between high iron levels and heart disease) that is hard to become acceptable becomes well established as a result of being evidenced by a well established, second correlation: the one between red meat and heart disease. Namely, the first correlation is most probably a function of the second correlation. |
