修改lynnuana的:
The speaker asserts, in the argument, that the moderate distress of infants and the shyness of teenagers later on is (are) caused by the excessive ingestion of melatonin during their fetal period. To support it
, he provides a follow-up study towards 25 children attempting to convince his audience. Unfortunately, due to the lack of several detailed experimental data and the unfounded analysis with some arbitrary causalities involved, the speaker’s conclusion seems unable to easily stand up.
First, the reduction of daylight could not be the only reason—even not the reason--- causing abnormal secretion of melatonin. As know to all, melatonin, as a natural and efficient sleep aid for the pregnant, is becoming popular for the time being. Most obstetricians and pharmacists would recommend melatonin tablets to the pregnant women to help regular sleep. Therefore, it is very possible that it is not the pregnant moms themselves who product the melatonin physically but the particular hormone medicine which potentially assist. Besides, even if the pregnant resisted taking any chemical, they could not avoid eating every day. Numerous kinds of foods, like milk, chocolate, corns, gingers and so forth, contain Melatonin. Once taking such kind of food too much, the moms also will excrete Melatonin anomaly. Finally, even if the pennant(这个单词打错了,pregnant moms) did not eat this kind of food, no evidence could bolster the assumption that sunlight in early autumn is the arch-criminal for melatonin secretion. Yes, human body would product more melatonin in the night than in the daytime. Yet this production has little relevance with sunshine but actually relates to the normal internal metabolism. Thus, whether in early autumn or not is probably not the reason for the mother to product more melatonin or less. In short, due to the reasons mentioned above, the speaker fails to offer a comprehensive cause analysis towards many other possibilities for over-level secretion of melatonin. (这一段用了让步式的攻击法,一层层地假设,再反推,说明了作者忽略了其他的可能性,melatonin的产生因素有很多。总之论证很充实,也很有层次感。语言流畅,句式也很灵活。学习了。)
Second, the speaker fails to make it clear that how much melatonin would be transported to the fetus. It is very possible that even if moms produced more melatonin, the fetus who would absorb little. Hence, the melatonin could only enter the maternal circulation with less provided to the fetus, which could not affect the fetal brain function directly, let alone the influence on the teenagers.(这里,进一步用了让步式地攻击法,还用了个对比)
Third, assuming melatonin indeed affect the brain function of fetus, no evidence reveals melatonin would be responsible for the personality formation of children. Maternal emotional and physical conditions would be the one(去掉) cause that impact the fetal character forming process. In another word, as the first connection between the fetuses and outside world, pregnant mothers’ emotion such as anger, grief, happiness or anxiety, or the pregnant age and health would definitely influence the fetuses from all aspects. Social environment is another cause. People would feel stress or uneasiness when staying in a new and totally strange place. This is human’s natural reaction. So does a child. That the infants, in the first test of the study, reacted with distress is probably not because of the voice and smell, but of the unfamiliar surroundings, such as the poker-faced researchers, the ice-cold test table or many children together, etc. As for the second test, on one hand, researchers did not provide the opinions towards the parents, teachers or peers of the teenagers to identify the youth as shy.,(原文中是teenagers觉得自已害羞,你这里有点怪)On the other hand, maybe the young people have experienced some tragedies from childhood to the teenage years, which results in the formation of shyness. Hence, whether melatonin would affect the personality formation of children is still open to doubt. (更进一步地用让步法攻击,说明了人的性格的形成因素是多种多样的,反驳了作者的观点)
Last but not least, the study, as the speaker highlights, is not so scientific and rigorous. Firstly, an experiment should make strict distinguish and definition between normal emotional reactions and abnormal or morbid reactions. But in the study, the researchers did not give such a clear division. The key words like “mild distress” or “shyness” is too broad. Secondly, the infant or youth samples are not adequately representative. Could the 25 infants represent millions of children in the world? Or could half of the teenagers (only 12 or 13 persons) represent them? The answer is absolutely no. Therefore, the unscientific or even arbitrary conclusion the speaker make would lead to a collapse of the whole analysis building.(主次攻击很明显)
A large Number of the youth in the world are suffering emotional problems at present. I appreciate the author’s concern about the children issues, yet his argument is unconvincing after a careful analysis. Such a statement would mislead the public opinion and to some extent, even bring about more potential social problems if put into practice.(小遗憾,有点放开了,可以围绕题目的结论,提出些建议)
点评:
我也是第一次写AGRUMENT,觉得你的算得上是一篇outstanding essay 了。跟你的一比,我的那篇磨磨蹭蹭的写得稀烂啊,惭愧~~你的作文让我学到了一些表达和行文的思路,学习了。
1.形式上,结构很严密,沿着一条逻辑链,一步步,一层层地反驳,层次感明晰,逻辑性很强。主要反驳了melatonin不一定导致婴儿期的羞涩。次要反驳了儿童性格的形成的原因。
2.内容上,材料很充实,论据还算丰富,展开式的讨论。
3.反驳方法上,大量地运用了让步攻击法,这样的一步步地深入,到最后就彻底驳斥了原文的整个逻辑体系。不要出现错误的假设就好了,有些时候主观上会太臆想了。还运用了主次攻击的方式,详略得当。
4,语言上,运用了多种句式,多音节的词也比较多,表达很丰富,可以看出功底不错啊,赞个!!我呀,底子薄,语言还没看出有什么错误或者表达上的不准确。。。
5.一小缺点,就是结尾处发散得太开了
