53Thirteen years ago, researchers studied a group of 25 infants who showed signs of mild distress when exposed to unfamiliar stimuli such as an unusual odor or a tape recording of an unknown voice. They discovered that these infants were more likely than other infants to have been conceived in early autumn, a time when their mothers' production of melatonin—a hormone known to affect some brain functions—would naturally increase in response to decreased daylight. In a follow-up study conducted earlier this year, more than half of these children—now teenagers—who had shown signs of distress identified themselves as shy. Clearly, increased levels of melatonin before birth cause shyness during infancy and this shyness continues into later life.

1 study --> unfamiliar stimuli --> signs of mild distress
2 study --> these infants were more likely to be conceived in early autumn --> the distress is caused by the increased melatonin
3 following study --> infants who shows distress identified themselves as shy
123 --> increased levels of melatonin before birth cause shyness during infancy and this shyness continues into later life.

1 mild distress 和在早秋怀孕 并没联系， 和melatonin更没关系
2即使上述关系成立 样本具有代表性吗？
3将distress和shyness等同了 而且幼时的shyness并不一定会延续到later life

Grounding on the study on the 25 infants who show signs of mild distress under unfamiliar stimuli and the follow-up study which shows their shyness when they become teenagers, and then synthesizing the two results, the author accordingly concludes that the increase of melatonin leads to the infants' shyness and this shyness continues to their later life. However, this argument contains a series of flaws, which contribute to its illogicality.

To begin with, the author relies on an unproven cause-and-effect relationship between the mild distress of infants and their conception in early autumn which their mothers' production of melatonin increased, nor to mention the relationship between the distress of the infants and the increased melatonin. It is entirely possible that the distress of infants is a physiological reaction to unfamiliar stimuli. Also there is another reason that the distress of the infants is attributed to other causes such as other hormones, genes, environment around them and so on. Without ruling out these possibilities, the author is unable to establish the cause-and-effect between the mild distress of infants and the increased melatonin of women, the author cannot confirm his conclusion base on the unpersuasive fact.

Even assume the relationship between the distress of infants and the increased melatonin exist. The author fails to judge the accuracy and validity of the study. Is the number of 25 infants enough to represent all the infants? Hardly could we reach the conclusion just relying on such few subjects. And how much more does the term "more likely" show the possibility of infants conceived in early autumn? May be there is just half of them are conceived during that time. Moreover, the following study lacks detailed portion of how many of these children are identified as shy by themselves with the term "more than half", which could be only 51% of them. Without take these into account, the research study cannot be valid to support the conclusion.

Last but not the least, the author’s hasty generalization according to the following study is a fallacy. The author falsely equates distress and shyness, without a clear definition of distress and shyness. It is very likely that the infants who the teenagers who identified themselves as shy may simply affected by their parents or friends. For lack of clear evidence to prove a man will continue to be shy in his later life according his shyness showed when he was young, the author's opinion that the infants who shows signs of distress will be shy when they grow up and this shyness will continue in their later life is untenable.

In sum, the author's recommendation is ill conceived and poorly supported. To strengthen the argument, the author must provide me more information about the relationship between melatonin and distress, the definition of distress and shyness is also needed. In order to better evaluate the suggestions, the author should ensure that the sample in the two studies can represent all the infants.

才看到要补逻辑链，
1，调查的样本太小，没有代表性，没有说服力。
2，婴儿的mild distress不代表着羞愧，也可以是其他的兴奋，快乐啊
3，没有证据说明meltonin会导致婴儿害羞，没有说明是否对婴儿有影响，，也没有说明是否对母亲有影响
4，人的性格不是一成不变的，生活环境，人的经历等等因素都会影响着人的性格。作者忽略了这些可能性，所以得出的结论是武断的。
       Based on a follow-up study in infants, the author presents the conclusion that increased levels of melatonin before birth cause shyness during infancy and this shyness continues into later life. The argument is relatively sound, however, it relies on a series of unsubstantiated assumptions, which render it unconvincing as it stands.
           First of all, the author uses a few exceptional cases as the basis for a claim about that melatonin is relative to the infants’ shyness. As mentioned in the argument, researchers studied a group of 25 infants who showed signs of mild distress when exposed to unfamiliar stimuli stimuli such as anunusal odor or a tape recording of an unknown voice. The sample for the survey includes only 25 infants, which capacity is too small to be lack of representation in general. Consequently, in the context of investigation of a small area, the statistical evidence of the survey upon which the argument relies is too vague to be persuadable.
      Secondly, it’s nevertheless impossible to assess the author's assertion that infants would show signs of mild distress , at least without an agreed-upon definition of that argument . On the one hand, the author fails to prove the signs could delegate a feeling of mild distress. In common sense, an infant cannot express his/her feeling through language and writing, so it’s possible that the signs are not mild distress, but others. Probably these signs are expressions of excitement or delighting. On the other hand, how could the researchers make sure the voice is unknown to the infants? Maybe the infants have been heard same voice which parents did not noticed. Meanwhile, lacking such evidence and scientific basis to explain the effectiveness of the melatonin, Whether this impact on infant, the author cannot reasonably conclude that infants would show signs of mild distress.
         Finally, the author’s assertion that shyness which results from melatonin continues into later life is not persuadable .For one thing,the study conducted earlier this year is unsubstantial. For aother thing, Personality is not static, precisely because very person grows in the complex social environment.
Obviously, the formation of character is not only due to postnatal development diversity, but also the parents’ affect , personal experience, and life environment. Such posibilitise would serve to undermine the author’s claim that shyness should continues into later life.
         In sum, the author’s assertion for the survey is ill conceived and poorly supported. To better assess the study’s reliability I would need more information about the infants .

母亲conceive在早秋


早秋日照少-->过多melation-->影响婴儿个性形成(对不熟悉的刺激紧张)-->13年后跟踪调查: 有一半以上认为自己害羞--->羞涩会延续到更晚年龄


The speaker asserts, in the argument, that the moderate distress of infants and the shyness of teenagers later on is caused by the excessive ingestion of melatonin during their fetal period. To support, 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 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.

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.

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 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. 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.

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.

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.

In this argument,the arguer concludes that increased levels of  melation before  
birth cause shyness during infancy and this shyness continues into later life.To  
strengthen this conclusion,the arguer provides a statisics about a study  
concerning 25 infants and a follow up study.At first glance,the argument
might be somehow reasonable, but close scrutiny reveals that it contains several  
unconvincing assumptions and is therefore unpersuasive.

First,the argument fails to assure me with an incomplete and selective  
comparison.Since the arguer cannot provide compelling evidence that infants who  
participated in the study are representative of all infants. Perhaps these infants  
get a some kind of disease whose sympton is mild distress when exposed to  
unfamilar stimuli,and the study lacking the information about how other infants  
acted in the circumstances of unfamiliar stimuli. Thus, I remain doubtful about  
the basis of the conclusion.

Second, even assuming that the 25 infants who have participated in the study are  
well representative of all the infants, the conclusion is base on an automatical  
assuming that this kind of mild distress is simply cause by their mothers'  
production of melatonin which is increased in early autumn. However, this might not  
be the case. The arguer obviously overlooks other possible explanations for this  
phenomenon. For example, perhaps the decreased daylight directly causes the mild  
distress, or perhaps a unknowing hormone from the infant itself brings about the  
distress. Without ruling out such possibilities, I cannot accept the arguer's point  
of the increased melatonin causes infants' mild distress.

Finally, even assuming that the melatonin cause infants' mild distress, the arguer  
unfairly indicates a causal relation between the infants' mild distress when  
exposed to unfamiliar stimuli and the shyness of them when they are growing  
up. There could be many other factors, such as circumstance where they were brought  
up and their characters, or the education they took and their parents’ influence  
on them into consideration. Without accounting for all other explanations, the  
arguer cannot reasonably conclude that shyness of the teenagers is caused by the  
melatonin.

To sum up, the arguer's conclusion about increased levels of melatonin before birth  
cause shyness during infancy and this shyness continues into later life is not  
supported as it stands. To bolster it, the arguer must provide more evidence, such  
as the function of the melatonin, how is effect the infants. To better assess the  
problem, I would also need to know the teenagers in.

In this argument the speaker claims that a group of 25 infants who showed signs of mild distress to unfamiliar stimuli are more likely to have been conceived in early autumn because of the increasing production of melatonin of their mothers. In addition, increased levels of melatonin before birth cause shyness during infancy and this shyness continues into later life. However, the author fails to provide several critical evidence to support the argument.

First of all, the author does not mention the situation of the other infants who did not show strong signs of mild distress when exposed to unfamiliar stimuli. Some of the other infants may have been conceived in winter, a time which has more decreasing daylight than autumn and when the mothers' production of melatonin naturally increase more according to what is mentioned in the argument.

What is more, even if all the infants who showed signs of mild distress have been conceived in early autumn while others in a time when there is shorter daylight than autumn, the author fails to prove the necessary connection between the melatonin and the phenomenon. It is pretty likely that the cause of signs of mild distress is other factors such as the temperature and humidity other than the increasing production of melatonin in autumn.

Last but not the least，even though it is the melatonin which lead to the infants' signs of mild distress when exposed to unfamiliar stimuli, the author falsely build an equivalence between shyness and mild distress. Much further explanation should be made to that shyness is relevant to distress. In short, without a clear definition of distress and shyness, we cannot simply regard shyness as exactly same as distress and it is impossible to access the strength of the argument.

In conclusion, the author does not successfully build a clear causal relation to support his own opinion.  To persuade the reader to accept the conclusion, the arguer must present more strong evidence about how melatonin affects the infants.

Logic chain
Decreased daylight in the early autumn-->melatonin increase during fetal period-->showing signs of mild distress-->13 years later more than half of them show shy-->increased levels of melatonin before birth cause shyness which continues into later life

Writing
The argument presented above is relatively sound that the author considered that the increased levels of melatonin during the fetal period, in the early autumn cause shyness during infancy and this shyness continues into later life. And a 25 samples study is used to support the author’s conclusion. However, the author fails to recognize all the elements necessary to evaluate his situation. To clarify, it may be necessary to point some doubts to this argument.

First, the author did not give the details about how the melatonin affects some brain functions and only one kind of hormone could make so much affecting causing shyness? As we know during the fetal period many kinds of hormones are all necessary, we can’t consider that only the increased levels of melatonin make it. May be some increase and some decrease, but how the others kind of hormones are taken in during the season of decreased daylight we don’t know in this argument. But in winter the daylights decreased more than in autumn. Why the author didn’t say the infants may be conceived in winter, that is logical, we also could not find the answer in this argument. And what is more important is that how the melatonin affects some brain functions and makes the infants show signs of mild distress when exposed to unfamiliar stimuli. We don’t see any necessary relation between melatonin and behave.

Even the increased melatonin really is the cause of shyness the infants have shown it is one of causes—not the only reason. The opinion that the shyness caused by increased levels of melatonin continues into later life could not be upheld. These children—now teenagers—who had shown signs of distress identified themselves as shy may be affected by many elements such as family, education, district where they live…and so on. Children could be affected easily even they may be like as each other when they were born. In the teenager period, who took regular education are mostly different from who took poor education or no education. How can you make sure that they maybe likewise identify themselves as shy? Who took regular education maybe feel confident because of their knowledge, however maybe their childhood were full of pressures and they acted shy in teenager period. So many unknown and unpredictable elements will happen to these children—now teenagers, who identifies himself as shy now may become open and chatty when he grow up and experienced more. The social environment, education, family, career, friendship, and physical condition are all the elements which can influence their characters. Obviously we can’t forecast what can change the children, so we can’t be sure that the shyness cause by the increased levels of melatonin continues into their life as the author said either.

Lastly, the number of samples is not enough to support the author’s conclusion either. So what I want to say is that the author’s conclusion may be right but it is short of enough details and logic. If he keeps on this study, he could consider it deeper and more complete as I said above. Considering more and more elements, the analysis will be reasonable and make other believe in it.

文章总的来说比我自己写的要流畅，鉴于本人英语基础差，在语言方面实在改不出什么~
问题是有的：
1.
首要的，第二段和第三段的论述有所重复，就是说第二段用于驳论的反例（infants may have been conceived in winter, a time which has more decreasing daylight than autumn and when the mothers' production of melatonin naturally）也可以用于第三段当反例。（这么一想自己的作文也有类似问题）是否应该在第二段寻求一个更好的关于原作无法证明25个infants代表整体的反例。
2.
别人看你写的argument也会当做一个argument的题目来看（比如阅卷人…），那么在写argument的时候就要注意自己写的东西是否会犯argument中类似的错误，比如false analogy，因为我们在反驳的时候只是举反面有可能的例子，那么话就不能说的太绝对。
3.
和我一样的问题是，感觉文章不够饱满，也许多写点就有形成自己的语言风格吧。

In this argument, the author concluded that increased levels of melatonin before birth cause shyness and will also affect on the later life. However, after scrutinizing the studies and the reasoning of the author, I think this argument is unconvincing in  some points.

Firstly, the author said that melatonin has influence on some brain functions, but no evidence shows that the increasing of melatonin can cause the shyness of infants. The author didn’t offer us the research of the melatonin; we don’t know the function of it, and then no one can prove that there is a direct connection with shyness and melatonin. What’s more, it’s not clear that whom the melatonin makes affect on, maybe this hormone has no influence on the infants but affects on the mother.

Secondly, the author ignored other possibilities which may also contribute to the shyness. There will be many other factors leading to the shyness of a child. For example, the living environment, characters of their parents, the education method, the experience they had and so forth. These factors always have many influences on the character formation of people. And it may play a more important role than melatonin.

Finally, to confirm a survey, we must choose a broad data. But the samples of this mentioned study is too limited. The researchers only study 25 infants, which is dubious to prove a study’s correction. In addition, we are not sure that whether the statistic could represent the overall infants and whether they selected infants randomly.  It is impossible to determine the authors claim on such a small and inexact data.  

In conclusion, the argument is not as convincing and logical as it stands. To strengthen it, the author should offer us some stronger connection of melatonin and infants. What’s more, the author had better take into account other possibilities that lead to the shyness of infants.

First,the argument fails to assure me with an incomplete and selective（selective是褒义词吧？认真挑选的严格挑选的意思。incomplete是贬义的，二者似乎不能用and平衡） comparison.Since the arguer cannot provide compelling evidence that infants who participated in the study are representative of all infants.（对上句的进一步解释，好！但是似乎句子没有写完“since...，然后呢？”或者since前面应该是逗号？） Perhaps these infants get a some kind of disease whose（of which the？） sympton is mild distress when exposed to unfamilar stimuli,and（建议另起一句，很像也包含在perhaps义群中） the study lacking（lacks） the information about how other infants acted in the circumstances of unfamiliar stimuli.

For example, the living environment, characters of their parents, the education method, the experience they had and so forth. These factors always have many influences on the character formation of people. （这三句觉得可以做成长句：many other factors---for example, the living environment, characters of their parents, the education method, the experience they had and so forth---would lead to the shyness of a child， even his character formation.）And it may play a more important role than melatonin. (如果变长句，这句就要改改了)----（缺少分论点结论句）

Finally, to confirm a survey, we must choose a broad data. But the samples of this mentioned study is too limited.（可以合成长句，一般来说，英语先说重点（你的观点），再补充其他） The researchers only study 25 infants, which is dubious to prove a study’s correction.（这句读着不对，是不是应该谈下25个infant的情况，才能说它不能prove study conclusion）
In addition, we（最好不用we，你只代表自己的观点） are not sure that（删？） whether the statistic could represent the overall infants and whether they selected infants randomly.  It is impossible to determine the authors claim on such a small and inexact data.  （这段中的in addition 似乎可以删去，因为都在表达一个意思）

In conclusion, the argument is not as convincing and logical as it stands. To strengthen it, the author should offer us some stronger connection of（between） melatonin and infants. What’s more,（重复词不要，moreover） the author had better take into account other possibilities that lead to the shyness of infants.

点评（个人意见，欢迎批评指正哈）
结构清楚，中间论证需要再深入挖掘，比如第一个分论点，只谈到“maybe this hormone has no influence on the infants but affects on the mother”就停了，其实可以继续挖一下“为什么”的。作为读者我就有疑问，为什么你说这个hormone会只影响母亲。
需要注意：
1 每个论证都要完整，需要包括主题句+body论证过程+结论句
2 需要加强英语思维来表达句子，在网上随便搜了下，给你作参考吧：英语句子是怎样通过英语思维说出来的
  多看看相关文章或者多读英语论文什么的培养英式思维表达
