　　难易程度：★★★

　　题目题材：公共卫生，社区

　　gre argument 80题目：

　　The following appeared as an editorial in a health magazine.

　　"Clormium 5 is an odorless, tasteless, and generally harmless industrial by-product that can enter the water supply. A preliminary study has linked cooking with water containing clormium 5 to an increased incidence of allergies and skin rashes(1). Tests of the drinking water(2) in several areas(3) have revealed the presence of clormium 5. Although it is possible to remove clormium 5 from water, the costs of routine testing and purification are higher than many communities can afford. Therore, in order to prevent allergies and skin rashes(4), communities that cannot afford to rid their drinking water of clormium 5 should replace drinking fountains in public buildings, such as schools and libraries, with bottled-water coolers(5,6,7)."

　　提纲：

　　(1)The editorial fails to establish a causal relationship between the presence of C5 and high incidence of allergies and skin rashes.

　　(2)The high incidence of allergies and rashes was only linked with cooking with water containing C5, no evidence could guarantee that drinking water containing C5 would also lead to the same result.

　　(3)The result of the test might not be representative of the whole region, in other words, maybe drinking water in most communities does not contain C5.

　　(4)Allergies and skin rashes might be cause by other reasons, thus merely removing C5 might not sufficiently prevent allergies and rashes.

　　(5)Granted that removing C5 is a necessary measure to prevent allergies and skin rashes, merely replacing drinking fountains with bottled-water coolers might not be sufficient.

　　(6)Other methods could also be applied to prevent these disease.

　　(7)There may be some negative fects of using bottled-water coolers.

　　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。
