~The argument that increased levels of melatonin before birth cause shyness during infancy and this shyness continues into later life seems at first glance to be an obvious conclusion. After all, it is based on the research on a group of 25 infants,(这里好像有说数量已经足够多的意思,可是后文马上又相应的反驳,这里不应该用来让步的吧) what's more, a follow-up study was conducted thirteen years later on the same 25 children-now teenagers. However, there are some assumptions that are not verified clearly and from which severe aftermath can result.
First of all, the most important thing is that the research isn't based on a large number of samples, but on 25 infants who showed signs of mild distress when exposed to unfamiliar stimuli. In addition, the research was not executed methodically, because of many differences between 25 infants and control. What matters for any scientific research is that not only should the result be derived from a great amount of samples, and that the research must also be carried out meticulously and exactly. For example, there is a poll over ten thousand of people, while only ten percentage give their feedback, does the poll still remain reasonable? No matter what study comes to ten percentage , it is meaningless, for the consequence does not possess representativeness.(这两句好像不太相关。原文并没有涉及到调查反馈者人数的问题,本来就已经明确了调查对象是只有25个人。你所攻击的问题应该是出现在调查结果说XX%的反馈人怎样怎样,而且没有告诉我们有多少人做了反馈吧)
As the argument presents, there are twice surveys: one survey is on 25 infants exposed to unfamiliar stimuli such as an unusual odor or a tape recording of an unknown voice, the other is a follow-up study conducted thirteen years later than the first one when the infants are teenagers. There is a 13-year interval, this is, the 25 infants might live in a completely same life as other infants, or might not. It is commonly believed as a proverbial fact that environments have huge effects on the characteristics of people, and this is especially true for children. Those infants who have no friends in their childhood will say no words and identify themselves as shy. Based on the reasoning mentioned above, how unconvincing the follow-up study is!
Finally, before I come to my conclusion, there are still some flaws need to be pointed out. First, as the arguer said, the production of melatonin in these 25 infants' mothers would naturally increase in response to decreased daylight, so do other infants' mothers, now that all mother are live under the same circumstance. Second, there is a vague define about the function of hormone dotted with affecting "some" brain functions. Third, in the follow-up study, more than half of the 25 children have the traits of showing shy, and what does “more than ” exactly mean? Forth, according to the result that increased dose of melatonin in conceived mother result in shyness, pregnant mothers for fetues good would bask themselves as more as they can, which can lead to skin cancer and is considerably harmful to fetuses. (最后一点怎么看不明白呀?晒太阳与褪黑激素有直接关系吗?对婴儿有害是有关皮肤癌的,和shyness有关吗?请指教)
All in all, the viewpoint of this argument that increased volume of melatonin in pregnant mother cause shyness during infancy and this shyness continues into later life is not thoroughly well-reasoned. Unless all other possible alternatives and causes are taken into account, the conclusion of this study isn't convincing.
语法错误没有改出来多少,文章的构架和思路比较的清晰,用词比较丰富。
有不少非陈述语句,让人读着不腻。不过,可以有感叹号出现吗?(这点我没有研究过),感叹号的出现会不会显得不理智?(只知道议论文里面是很少用感叹句)
主体部分的后面两段写非常详细,考虑的比较全面。与官方analyze in detail这个要求很相符。尤其是finally,还指出了这么多纰漏,写的还很清晰··但是有一个疑问,真的这些DETAIL对与这个结论有颠覆性作用吗?好像有的听上去不是那么搭边(个人看法而已)
总的来说还不错的,继续加油噢!
