　　gre argument 167题目：

　　A folk remedy* for insomnia, the scent in lavender flowers, has now been proved fective. In a recent study, 30 volunteers(1,2) with chronic insomnia slept each night for three weeks on lavender-scented pillows in a controlled room where their sleep was monitored(7). During the first week, volunteers continued to take their usual sleeping medication. They slept soundly but wakened feeling tired(4). During the second week, the volunteers discontinued their medication. As a result, they slept less soundly than the previous week and felt even more tired. During the third week, the volunteers slept longer and more soundly than in the previous two weeks(3,5). This shows that over a short period of time lavender cures insomnia(6,8).

　　*A folk remedy is usually a plant-based form of treatment common to traditional forms of medicine, ones that developed bore the advent of modern medical services and technology.

　　提纲：

　　(1)30 volunteers are too small a sample that can hardly be representative.

　　(2)We do not have any detailed information about the 30 volunteers, e.g. the severity of their insomnia, their physique, etc., thus we could not evaluate if they are representative.

　　(3)The author does not inform us about the volunteers&apos sleep patterns prior to the experiment.

　　(4)How soundly or long a person sleeps, or how tired a person feels after sleep, is irrelevant to whether the person suffers from insomnia.

　　(5)The study fails to inform us how the volunteers felt after sleep during the third week, thus we could not evaluate the actual fect of lavender flowers on sleep.

　　(6)Granted that the volunteer’s sleep was improved through the three weeks, we cannot ensure it is the lavender that caused the result, other factors could also account for the improvement.

　　(7)The study should include another group of people who do not sleep on such pillows as counterparts.

　　(8)The author cannot hastily conclude that the volunteers’ insomnia has been thoroughly cured without any follow-up studies.
