In this argument, the writer's conclusion that increased levels of melatonin before birth cause shyness during infancy and this shyness continues into later life on the research of only 25 distressed infants ,which is not based on large enough samples, is ungrounded.
  First, as mentioned before, the situation of the only 25 infants in the study is insufficient to demonstrate all of the infants. The writer should observe more cases and do further research to come to his conclusion that the part of infants will represent all of the infants.
  Second, the argument lacks certain relationship between the increasing secretion of melatonin and the early autumn. The writer bases on the reason that (because 删去） the daylight decreases , so the melatonin of the mother which is thought to affect some brain functions will increase. The conclusion that the early autumn equals to the decreased daylight is unwarranted. If the writer doesn't give me more details about this ,I will not be convinced.
  Third ,even if there is increasing in the melatonin in the mother, how does it shape the disposition of the infants? I can only know from the argument that the melatonin may affect some brain functions, but whether it will make infants be distressed or not is not clear. The arguer should demonstrate more reasonable evidence.
  Finally, the fact that more than half of these children who had shown signs of distress identified themselves as shy when they had become teenagers doesn’t mean that all the distressed infants will definitely grow into shy
teenagers. The environment in the later life is more important in determining one’s characteristics. In this point, there is no certain relationship between the increasing of melatonin and the later life shyness.
  In sum, there is no data available to convince us that the increased levels of melatonin in mother make the children shy and the shyness last for the later life. More practices and researches should be done.

我也是鸡蛋里挑骨头了～呵呵
第二个论点好像有点问题，早秋确实是日光减少，arguer应该交代的是早秋或日光减少如何能引起该激素的增加。
