　　难易程度：★★★

　　题目题材：商业

　　gre argument 170题目：

　　For the past five years, consumers in California have been willing to pay twice as much for oysters from the northeastern Atlantic Coast as for Gulf Coast oysters. This trend began shortly after harmful bacteria were found in a few raw Gulf Coast oysters(3). But scientists have now devised a process for killing the bacteria(1,2). Once consumers are made aware of the increased safety(4) of Gulf Coast oysters, they are likely to be willing to pay as much for Gulf Coast as for northeastern Atlantic Coast oysters(5), and greater profits for Gulf Coast oyster producers will follow.

　　提纲：

　　(1)The author does not inform us the costs of employing the process, Gulf Coast oyster producers will be profitless if the costs are high.

　　(2)There may be some undesired fect of using the process, e.g. affecting the taste of oysters, killing some benicial nutrition in oysters, etc.

　　(3)The author unfairly assumes that the difference in the prices of the two kinds of oysters results from the discovery of harmful bacteria in Gulf Coast oysters.

　　(4)The author fails to inform us the actual fectiveness of the process, thus the assumption that installing the process will necessarily lead to increased safety of Gulf Coast oysters is unjustifiable.

　　(5)We cannot guarantee that consumers are willing to pay the same amount of money once Gulf Coast oysters are proved to be safe.

　　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。
