TOPIC: ARGUMENT81 - Allergies are an overreaction of the immune system to certain stimuli. One view is that allergies can develop as the result of childhood exposure to certain irritants, such as dust or animal dander, while the immune system is not yet mature. Another view is that exposure to particular bacteria early in childhood actually triggers the proper development of the immune system, and that limiting exposure to these bacteria through excessive hygiene can cause children's immune systems to overreact to certain irritants later on. A new study supports the second view: children who are washed especially frequently and whose parents clean their homes especially frequently are more likely to develop allergies than are other children. So in order to reduce the incidence of allergies in children and adults, parents should not limit children's exposure to irritants or bacteria.

In this argument, the author asserts that children should be exposed to irritants or bacterial in order to develop their immune system. To support his/her conclusion, the author cites the study taken on two groups of children, in which the groups of children who are washed especially are more likely to develop allergies. While appealing at first glance, the argument rest on a series of unsubstantiated assumptions which make the conclusion unconvincing as it stands.
First of all, the author fails to provide enough information about the study. How many children are involved in the study and are they of the same age or same health condition? It is entirely possible that only small number of children, like five, take part in this study which makes the results of the study unconvincing. What's more, the children who receive special hygiene treatment may posses the syndrome of allergy before they join the study which makes the study an unfair one. The study should be statistically reliable, however, we can see no sign of this procedure in the argument which makes the conclusion completely unwarranted.
Secondly, even if the procudure the study takes is correct, which is unsubstantiated, it does not necessarily follow that it is the limiting exposure to bacteria through excessive hygiene that leads to allergies. The reasons are as follows. First, even children in one group are washed especially frequently and their living environment are cleaned carefully, it does not necessarily mean that they experience the excessive hygiene. It appears reasonable that still huge amount of bacteria and irritants exist everywhere. The author does not provide sufficient evidence to rule out this case. Second, there are other alternatives that the author should have taken into account. Such alternatives may include the genetic reasons. It is possible that children get the allergy directly from their parents through heredity but not the excessive hygiene. Similarly the other factors like food, their toys, people they interact can all leads to their allergy. Before further investigation and analysis are made, it is still early to conclude.
To sum up, the author's conclusion on expose children to irritants or bacteria to develop immune systems is not well-supported. To substantiate his conclusion, the author should provide more information about the environment the children live to sweep out other factors which might also lead the allergy. To better evaluate the recommendation, details about the study should be presented.

我觉得反例觉得都很好,问题发现的很准,分析很全面,尤其是说到了基因的问题。
看来LZ生物很好哈:)
语言的问题也很少,读起来很顺。
膜拜ing
继续加油吧!
