gre作文大讲堂：argument158提纲

158.(卫生健康，社会/论断/——)The Trash-Site Safety Council has recently conducted a statewidestudy(5) of possible harmful effects of garbage sites on the health of peopleliving near the sites. A total of five sites and 300 people(1) were examined.The study revealed, on average, only a small statistical correlation betweenthe proximity of homes to garbage sites and the incidence of unexplainedrashes(2) among people living in these homes. Furthermore, although it is truethat people living near the largest trash sites had a slightly higher incidenceof the rashes, there was otherwise nocorrelation between the size of the garbage sites and people's health(4). Therefore,the council is pleased to announce that the current system of garbage sitesdoes not pose a significant health hazard(3). We see no need to restrict thesize of such sites in our state or to place any restrictions(6) on the numberof homes built near the sites.

★★★

1、For lack of data concerning the total amount of garbage sites and people living near them in the state, the reliability of the study is open to doubt. (quantity of the sample) ★★★

2、The argument treats a lack of proof that current system of garbage sites will pose some extent of health hazard as constituting sufficient proof that it will not pose any significant health hazard. (do the statistics make any difference?) ★★★★★

3、以下省略

第二点的as应该是“当”的意思把?我的理解为：当提出足够论据证明垃圾不会有危害时，却没有证明垃圾存在一定的危害。

好奇怪，垃圾堆和危害的关系按常理就可以联系起来，题干中就是做这么一个survey(虽然survey得过程有很多令人怀疑的东西)来确定是否两者有关联，当然不用事先声明垃圾和危害有关联...
