In this argument, the author summarizes a study which concludes that the commercial use of salicylates(I use SAL instead) results in a steady decrease in the average number of headaches in twenty years. Although there are several fallacies in this study, the author hasty recons that further using of SAL will lead to a continued steady decline in the number of headaches suffered by the average citizen of Mentia. The argument seems to have some truth is the first glance, however, further scrutiny reveals it suffers from several fallacies discussed below.
First of all, the author fails to persuade us that the study was conducted in a scientific way in this argument. For one thing, the author omits the information of the participants. How many participants involved in? The larger of the size of the sample, the less likely the differences arise solely from random fluctuations. What is the health condition of participant? Healthy condition could be an important factor affecting headaches. Are they chosen randomly or according to a specific standard? The specific standard also needs to be taken in to consideration for result analysis. For another, the author fails to provide the information about the relationship between participants' diet and foods adding SAL. There is a possibility that some participate rarely eat this kind of food. In that case, there is no relationship between foods adding SAL and headache releasing.
Secondly, the author fails to demonstrate the cause and effect relationship between foods adding SAL and headache releasing. Except the omission of how the participants involve with the foods adding SAL, the author fails to rule out the other causing factors of headache releasing. With the development of modern society, novel drugs come out and new clinic methods are created. Do these participants use other drugs or meditational methods to cure their headache? In additon, the side effect of SAL needs to be taken into considerations, too. If SAL harm normal human organs or metabolisms, we should seriously concern about the commercial use of SAL.
Lastly, even assuming the study is correct; it is unwarranted to apply it to the citizen of Mentia. Because the author do not mention where the participants come from, we could not directly apply the result of this study into a specific area, Mentia. Unless, the participants are randomly choosen from Mentia, the recon is effective.
All in all, the study cited by this argument suffers from several fallacies. To substantiate it, the author needs to show us a scientific way to choose samples and conduct this research. Otherwise, the statement is untenable.
======================第一次自改文===============
In this argument, the author summarizes a study which concludes that the rise in commerical use of salicylates(I use SAL instead) results in a steady decrease in the average number of headaches in twenty years. Although there are several fallacies in this study, the author hasty concludes that further using of SAL will lead to a continued steady decline in the number of headaches suffered by the average citizen of Mentia. The argument seems to have some truth is the first glance, however, further scrutiny reveals it suffers from several fallacies discussed below.
First of all, the author omits the background information of the participants. Firstly, how many participants involved in? The larger of the size of the sample, the less likely the differences arise solely from random fluctuations, which share the same principle with scientists test the effect of a new drug. Before the drug are allowed to use in clinic, thousands of hundreds of volunteers needs to be observed after taking this drug. Secondly, what is the health condition of participants? Healthy condition could be an important factor affecting headaches. Do the participants have a good health which allows them recover fast after doing some exercise or using some drugs? Or, do they are in a bad health condition who are susceptible to some other diseases. Without taken the background condition of the participants into consideration, the author’s statement is less persuasive.
Secondly, the author fails to demonstrate the foods adding SAL causes headache releasing. For one thing, the author fails to provide the information about the relationship between foods adding SAL and participants' diet. There is a possibility that some participate rarely eat this kind of food. In that case, there is no relationship between foods adding SAL and headache releasing. For another, except the omission of how the participants involve with the foods adding SAL, the author fails to rule out the other causing factors of headache releasing. The changes in people’s diet, weather, and living habit would all contribute to headache releasing. And with the development of modern society, novel drugs come out and new clinic methods are created. Do these participants use other drugs or meditational methods to cure their headache?
After all, the side effect of SAL needs to be taken into considerations, too. If SAL harms normal human organs or metabolisms, we should seriously concern about the commercial use of SAL. If SAL have any serious side effect, its effect on headache curing is meaningless.
Even assuming the study is scientific; it is unwarranted to apply it to the citizen of Mentia. Because the author do not mention where the participants come from, we could not directly apply the result of this study into a specific area, Mentia. Unless, the participants are randomly choosen from Mentia, the recon is effective.
All in all, the study cited by this argument suffers from several fallacies. To substantiate it, the author needs to show us a scientific way to choose samples and conduct this research. Otherwise, the statement is untenable.
To 小c
cause and effect relationship我不确定,所以我改了。。。。
大刀阔斧的改,希望这样好一点。 |
