　　gre argument 187题目：

　　The following appeared as part of an article in a health magazine.

　　"A new discovery warrants a drastic change in the diets of people living in the United States. Two scientists have recently suggested that omega -3 fatty acids (found in some fish and fish oils) play a key role in mental health. Our ancestors, who ate less saturated fat and more polyunsaturated fat, including omega -3 fatty acids, were much less likely to suffer from depression than we are today(1). Moreover, modern societies—such as those in Japan and Taiwan—that consume large quantities of fish report depression rates(2,3) lower than that in the United States(4). Given this link between omega -3 fatty acids(5) and depression, it is important for all people(9,10) in the United States(6) to increase their consumption of fish(7,8) in order to prevent depression."

　　提纲：

　　1. Many other factors could explain why our ancestors were less likely to suffer from depression than we are today.

　　2. The dinition of depression may be different in the United States and in Japan or Taiwan.

　　3. The reported depression rates may not rlect the actual status of mental health of people, many other factors could explain the lower reported rates.

　　4. The author unfairly attributes the lower incidence of depression in Japan and Taiwan to consuming large quantities of fish.

　　5. Even if eating fish is responsible for the lower depression rates, we cannot hastily assume that it is the omega-3 fatty acids contained in fish that result in the case.

　　6. Granted that eating a lot of fish do benit Japanese and Taiwanese on their mental health, no evidence could ensure the same good fect will also occur among people in the United States through eating fish.

　　7. Omega-3 fatty acids are not necessarily contained only in fish, the author ignores many other solution to solve the problem.

　　8. Omega-3 fatty acids are not necessarily contained in all fish, thus consuming fish indiscriminatingly may not suffice to prevent depression.

　　9. The author fails to substantiate the assumption that all people in the United States need to consume a large amount of fish.

　　10.The author ignores the possibility that some Americans may not be willing to eat a lot of fish, some may not be fit for eating more fish, or some simply could not afford to do so.

　　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。
