标题: GWD-10-Q40 该选B还是D呢 [打印本页] 作者: 小玲珑 时间: 2010-5-29 22:03 标题: GWD-10-Q40 该选B还是D呢 GWD-10-Q40 Insect infestations in certain cotton-growing regions of the world have caused dramatic increase in the price of cotton on the world market. By contrast, the price of soybeans has long remained stable. Knowing that cotton plants mature quickly, many soybean growers in Ortovia plan to cease growing soybeans and being raising cotton instead, thereby taking advantage of the high price of cotton to increase their income significantly, at least over the next several years. Which of the following, if true, most seriously weakens the plan’s chances for success? A. The cost of raising soybeans has increased significantly over the past several year and is expected to continue to climb. B. Tests of a newly developed, inexpensive pesticide have shown it to be both environmentally safe and effective against the insects that have infested cotton crops. C. In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.时间范围无关 D. Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying. E. The species of insect that has infested cotton plants has never been known to attack soybean plants.
答案选了B, 而我原来选了D. 之后想想，觉得B和D都能weaken原文的成功率。
B是直接weaken了conclusion的future background-原来是 Insect infestations in certain cotton-growing regions of the world，而现在可以用很管用的pesticide了，就不会减产了，棉花的价格也不会再飙升了，所以soybean peasants’ transferring to grow cotton is not that much profitable.
D是说消费者在未来的愿意为棉花支付的价格将比现在的那种high price下降，我觉得这同样导致soybean peasants’ transferring to grow cotton is not that much profitable. （因为需求下降了，价格也会下降啊。）
B直接weaken了，D不一定weaken吧，需求下降，价格也下降这是你自己加的条件，题目没给。 你想太多了作者: 小玲珑 时间: 2010-5-29 22:51 标题: 在哪有专门讨论GWD的题的帖子呢 对不起，更正下，是我在D的括号里的表述有问题，不是“因为需求下降，而导致价格也下降”。你还是看原文的D选项吧, Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying, 就是说很少有人愿意为棉花付比现在更高的价格，就是直接谈价格的事。所以我还是觉得D也可以weaken 啊？
