　　难易程度：★★★★

　　题目题材：卫生保健

　　gre argument 81题目：

　　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(3), and that limiting exposure to these bacteria through excessive hygiene can cause children&aposs 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(1) are more likely to develop allergies than are other children(2,4). So in order to reduce the incidence of allergies in children and adults, parents should not limit(5) children&aposs exposure to irritants or bacteria.

　　提纲：

　　(1)The author simply equates frequent wash and home cleaning with excessive hygiene.

　　(2)Other factors could also result in the higher incidents of allergies in children who are frequently washed and whose homes are frequently cleaned.

　　(3)No direct evidence is provided to demonstrate that exposure to bacteria does lead to proper development of the immune system.

　　(4)The author fails to provide proper information about the incidence of allergies of the two groups of children when they grow up.

　　(5)Limiting children’s exposure to dangerous irritants or bacteria to some extent would still be necessary.

　　注：题目中括号里的数字表明这句话体现的是提纲中第几号缺陷。

　　无论是gre issue还是gre argument，考生都应该养成写提纲的习惯。这种提纲式的gre写作练习可以帮助考生锻炼写作的逻辑性，而gre写作高分最重要的得分依据就是作文的逻辑性要强。
