题目：ARGUMENT162 - 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.

In this artical,the author assert that North Americans should eat soy regularly to prevent fatigue and depression.To support this assertion,the author provided a statistics between suffering chronic fatigue and choronice depression people in North American and doing people living on the continent of Asia.Moreover,the author gives us annother evidence that Asians consist to eat soy everyday,but North Americans are not.However there are some fallacies both in the inference and conclusion.Without ruling out some detail imformation,the author cannot convine me effective.


Firsty, the author base on a fallacy of false analogy.The much more conditions in North American is differ from in Asian,such as,environment,diet habit,climate factor and so on.But the author concluds that Asian get less chronic depress and chronic fatigue than North Americans because they eat  soy,but the people living on the continent of North American are not.The author only considered the soy foctor,but there are much more foods that Asians eat but a morjority of North Americans do not.For instance,Chinese often cooks some internal organs within animals' bodies,on the contrary,North Americans could not torrelect.These internal organs also have some phytochemicals,perhaps they can decrease the rate of suffering chronic fatigue and chronic depression.And in the other aspect,the wonderful environment causes people healthy.The pollution in North America may be more serious than the continent of Asia.Although physical health is not sufficient factor of mental health,it is a necessary factor of mental health.People often get the physical demand,then to think about the mental demand.If the environment is too bad,people cannot care about their mental life.So they would not have any depression,they must put the improvement of environment firstly.In short,without accouting for possible difference between the conditions in Asia and conditions in North Amercan,the author cannot convince me the assertion for North Americans is so sound.

Similarly,the author confused a concrurrence with causal relationship.The author obsevers a correlation between Asians eat soy but North Americans do not and North Americans get higher ratio of suffering these mental disease.However,there are also some people in the Asia which suffering the chronic fatigue and chronic depreesion.As we know,the continent of Northe America has a lot of developed country.So the people living on the continet of North American would have more competitions that they must work hard to be better than their competitors.As these conditions lead to a lot of pressure,people would suffer the chronic fatigue and chronic depression easily.Ather all,the pressure of rapid daily lives could lead to the chronic fatigue and chronic depression.The growing number of people to see a psychological dotor in North American cities  is a good evidence to explan that rapid rhythm bring these mental disesases.Without ruling out all other such factors it is unfair to conclude that eatting soy can preventing fatigue and depression.

Finally,the assertion is too hasty to generalize.A kind of phytochemical call isoflavones was found in soy.To the advance research,we know it can prevent some disease.Nevertheless,the author unfair assumed that isoflavones could prevent the fatigue and depression.Perhaps the real reason that soy could prevent  mental diseases is the high quantity of protein.Because protein support the circulation of human bady.High protein causes human beings feel better.Thus,without additional samples illustrating the isoflavones have a function of preventing fatigue and depression,i cannot accept  the author's sweeping genneralization.

In sum up,the assertion is unwarranted.Author must concern all the difference between North American and Asia.And take a test to prove the soy could prevent mental disease.
