In this argument, the author makes a prediction that the number of headache patients in Mentia will steadily decline due to a widely(wide) use of Salicylates in food industry as preservatives and flavor additives. To support this statement, the author cited a study of the relationship between the use of salicylates and headaches. However, the result of study doesn't strongly lead to the conclusion meanwhile his reasoning suffers from(不知道可不可以这样用, 这个词的主观意义更重一些,文中作者不知道是自己有错误的.) some serious flaws.
The study may have found some correlation between salicylates and headaches, but the author offers no evidence to show that this correlation is a causal relationship.(这句略显Chinglish,前半句的意思可以不说,或者说同时发生不代表有causal relationship.意思是对的~~) Perhaps the decline in headaches they discovered in their participants is due to some medicine, or merely an improvement of circumstances.(可能原因可以展开几句,比如生活水平提高,习惯改善等等...)
Also the number of participants and the proportion of those who got rid of headaches during the twenty-year study is not given. What's more whether they eat food with salicylates remains to be seen(checked/examined…). All of the above makes the assumption, namely(不知可否引导从句) salicylates in food works to reduce headaches, more unconvincing.
In addition, since the author points out that many foods are naturally rich in
salicylates, then why does headaches have been inflicting us for such a long time? (这个批驳有些偏题的感觉,说道us自己了,不太基于材料. )
This fact from another aspect reveals the disability of the author's assumption.
Moreover, Even if we concede that salicylates do have some use in treating headachs. The author is still too quick(hasty) to expect a continued steady decline in the number of headaches in Mentia. No signs show that citizens in Mentia regularly eats food with salicylates, thus the prediction may be merely a guess. Also, the proportion of salicylates in food, whether as preservativesor flavor additives is probably too small to make these food a good treatment for headaches. Finally, the author fails to exclude the possibility that some other chemicals in food could even cause or aggravates headaches.(不仅仅food,其他比如工作压力更大\环境污染等等也是反例.这几点有点拖沓. ) Hence it is clear that without a more careful examination, the prediction is not trustworthy.
个人觉得还有一点是,开头说S物质和阿司匹林同族. 但是同族不代表同化学性质, 这一点也可批驳, 而且也比较容易.
To conclude, the argument do provides some information about a potentially(最好不用,会被认为你承认了S物质的功效.) useful chemical in treating headaches. However, the evidence he shows is far from enough to support his optimistic prediction of a decline in headaches.(这句不错~~)To make this argument more convincing, the author is advised to do some deep research(貌似特指的话应该是可数名词) into the characteristics of salicylates. Clinical trials are also needed. After all, a false belief in the function of chemicals in food may be dangerous to people suffering from headaches, or any other diseases.
总体来说有点乱的感觉,是不是调换一下顺序会更顺畅一点. 第三个攻击点有点偏题,可以换一个.
语言有些不太通顺,需要改进. 大家都有Chinglish的问题, 要习惯转换思维吧.
想到的就这么多,欢迎讨论~ |
