难易程度：★★★★
题目题材：医药
gre argument5题目：
The following appeared in the business section of a newspaper.
"Given that the number of people in our country with some form of arthritis is expected to rise from 40 million to 60 million over the next twenty years, pharmaceutical companies that produce drugs for the treatment of arthritis should be very profitable(1). Many analysts believe that in ten years Becton Pharmaceuticals, which makes Xenon, the best-selling drug treatment for arthritis, will be the most profitable pharmaceutical company. But the patent on Xenon expires in three years, and other companies will then be able to produce a cheaper version of the drug(2). Thus, it is more likely that in ten years the most profitable pharmaceutical company will be Perkins Pharmaceuticals, maker of a new drug called Xylan, which clinical studies show is preferred over Xenon by seven out of ten patients suffering from the most extreme cases of arthritis(3,4)."
gre argument5提纲：
（1）The arguer falsely assumes that a rise in the number of arthritis sufferers implies a rise in profitability for arthritis drug manufacturers, future competition may diminish the profit for each individual company.
（2）The expiration of the patent on Xenon does not necessarily lead to the decline in the profit of Becton, because Becton may have the advantage of market seniority.
（3）The preference of particular patients does not indicate that Xylan is a more profitable drug, we do not know the manufacturing cost and sales price of Xylan.
（4）We do not know what fraction of patients suffer from the most extreme cases of arthritis.
（5）There may be new companies and new technology emerging in the future.
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。
