GRE写作备考2012:GRE作文范文大全(115)
Finally, the reliability of the first study rests on its statistical integrity. The argument fails to
indicate what portion of the people surveyed actually responded; the smaller this portion, the
less reliable the results. Nor does the argument indicate how many people were surveyed, or
whether the sample was representative of Leeville's general population. Again, the smaller the
sample, the less reliable the results.
In conclusion, the assertion that respondents in the first study misrepresented their reading
habits is untenable, in light of a variety of alternative explanations for the apparent discrepancy
between the two studies. To strengthen the argument, its proponent must show that the
respondents in the first study are representative of Leeville citizens generally, and that both
groups are equally likely to check out books from Leeville's public libraries. To better evaluate
the argument, we would need to know the length of time between the two studies, and whether
any significant demographic changes occurred during this time. We would also need to know
the availability of literary classics compared to mystery novels at Leeville's public libraries.
Argument 50
A recent study shows that people living on the continent of North America suffer 9 times more
chronic fatigue and 31 times more chronic depression than do people living on the continent of
Asia. Interestingly, Asians, on average, eat 20 grams of soy per day, whereas North Americans
eat virtually none. It turns out that soy contains phytochemicals called isoflavones, which have
been found to possess disease-preventing properties. Thus, North Americans should consider
eating soy on a regular basis as a way of preventing fatigue and depression.
This argument condudes that North Americans should eat soy on a regular basis as a
means of preventing fatigue and depression. The argument cites a recent study showing that
North Americans suffer far greater from these problems than people in Asia do, that Asians eat
soy regularly whereas North Americans do not, and that soy is known to possess
disease-preventing properties. The argument relies on several doubtful assumptions, and is
therefore unconvincing. 感谢您阅读《GRE作文范文大全(115) 》一文,出国留学网(liuxue86.com)编辑部希望本文能帮助到您。
