　　gre argument 154题目：

　　The following appeared in the editorial section of a health and fitness magazine.

　　In a study of the effects of exercise on longevity, medical researchers tracked 500 middle-aged men over a 20-year period. The subjects represented a variety of occupations in several different parts of the country and responded to an annual survey in which they were asked: How often and how strenuously do you exercise? Of those who responded, the men who reported that they engaged in vigorous outdoor exercise nearly every day lived longer than the men who reported that they exercised mildly only once or twice a week. Given the clear link that this study establishes between longevity and exercise, doctors should not recommend moderate exercise to their patients but should instead encourage vigorous outdoor exercise on a daily basis.

　　提纲：

　　The 500 middle-aged men could only constitute a limited sample and can hardly be representative.

　　The study only tracked middle-aged men, thus the effect of vigorous outdoor exercises on women is still open to question.

　　A 20-year time span may not be a period which is long enough to ensure a decisive conclusion.

　　The author only considers people who responded to the survey, we still do not know the relationship between exercise and longevity in those who did not respond.

　　The author fails to rule out the possibility that those who engaged in vigorous outdoor exercises do so merely because they had outstanding physique.

　　Vigorous exercise may be beneficial for some people, but it does not follow that vigorous outdoor exercise will benefit all individuals, especially the patients.
