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.

The speaker concludes that parents should not limit children's expose to irritants or bacteria for the reason that it can reduce the incidence of allergies in children and adults. In order to support that conclusion, the speaker cites a new study which makes a comparison between a group of children who are washed especially frequently and live in a clean home environment and another group of children who don't. The result of study seems support that speaker's conclusion. However, after carefully analyzing, I find out many logical fallacies in the argument which I will discuss as follow.

To begin with, the speaker fails to give evidence to the conclusion that exposure to particular bacteria early in childhood can promote the development of the immune system. The study given by the author just takes into account the relationship between children's allergies and their washing and clean home environment but doesn't about the development of the immune system. Therefore, it is arbitrary the author conclude that the new study supports the second view without more information about the development of the immune system.

What's more, the study makes a comparison between two groups of children, but fails to give more related information about these two groups of children such as physics condition, ages and so on. It is possible that the children who are washed especially frequently and whose parents clean their homes especially frequently have allergies before the study. Their parents treat them so carefully just because their allergy. In the case, common sense tells us the children who have allergy more likely to develop allergies than other children. The author fails to ensure that the two groups of children are comparable. Therefore, the conclusion is unconvincing.

At last, the author conclude that parents should not limit children's expose to irritants or bacteria but fails to take account of the dangerous of such expose. Even it is true that expose to irritants or bacteria can avoid children from the allergies, but the expose may bring other damages to children's bodies. We all know that bacteria are bad for one's health. The author fails to take account of the dangerous, so his or her suggestion is infeasible.

To sum up, the argument is not convincing as it stands. In order to make the argument more persuasive, the author should provide evidence to prove the study he or she cited is authoritative. What's more, it is necessary to ensure that expose to irritants or bacteria will not bring other diseases to children.

弱弱地问一下, 引用了一个调查，可以用 city a study么?
