　　gre argument 168题目：

　　Typically, as people age, their bone mass decreases, making them more vulnerable to bone fractures. A recent study concludes that the most fective way(9) to reduce the risk of fractures in later life is to take twice the recommended dose of vitamin D and calcium daily(10). The three-year study followed a group of French women(1,2) in their eighties who were nursing-home residents. The women were given daily supplements of twice the recommended dose of vitamin D and calcium. In addition, the women participated in a light weightlifting program(5). After three years, these women showed a much lower rate(3) of hip fractures(6) than is average for their age(4,7,8).

　　提纲：

　　(1)The study only followed female sample, thus the fectiveness of the treatment on male could not be assessed.

　　(2)The group of French women may not represent the general population.

　　(3)The author does not inform us the physical condition of the French women bore they participated in the study, thus we cannot evaluate the actual fect of vitamin D and calcium on aged people.

　　(4)The author fails to illustrate that it is the intake of vitamin D and calcium that helped lowering the rate of hip fractures among the French women.

　　(5)The author fails to rule out the light weightlifting program and other factors as the cause of the lower rate of hip fractures among these women.

　　(6)We do not know the level of incidence of other kind of bone fractures among these women, thus the fect of the treatment cannot be ficiently evaluated.

　　(7)Without another group of similar women were included as a counterpart, the reliability of the study is not guaranteed.

　　(8)Lacking any subsequent studies of the health status, especially levels of bone fractures of these women in the following years, we could not hastily conclude that the treatment is fective to reduce the risk.

　　(9)The author ignores other fective ways to reduce the risk of fractures in later life.

　　(10)The author fails to analyze if there is any negative fect of taking more vitamin D and calcium than recommended dose on old people’s health.

　　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。
