※ 引述《amo18 (要打什麽啦)》之铭言： : ※ 引述《chihyi091 (双鱼座女生)》之铭言： : : 2. GWD-29-Q27 : : Though sucking zinc lozenges has been promoted as a treatment for the common : : cold, research has revealed no consistent effect. Recently, however, a zinc : : gel applied nasally has been shown to greatly reduce the duration of colds. : : Since the gel contains zinc in the same form and concentration as the : : lozenges, the greater effectiveness of the gel must be due to the fact that : : cold viruses tend to concentrate in the nose, not the mouth. : : In order to evaluate the argument, it would be most helpful to determine : : which of the following? : : A. Whether zinc is effective only against colds, or also has an effect on : : other virally caused diseases : : B. Whether there are remedies that do not contain zinc but that, when taken : : orally, can reduce the duration of colds : : C. Whether people who frequently catch colds have a zinc deficiency : : D. Whether either the zinc gel or the lozenges contain ingredients that have : : an impact on the activity of the zinc : : E. Whether the zinc gel has an effect on the severity of cold symptoms, as : : well as on their duration : : ANS: D : : 这题我选B耶 : : CD上这题是在争B和D : : 虽然大部份的人觉得是D : : 但我还是不懂为什麽D比较好~ : : 先谢谢回答罗~~ 我觉得这题答案是D 一起来讨论一下罗^^" : 治疗方法 Z比L好 因为病毒都集中在鼻子中 : 一样是衡量当假设作 选项对错是否影响原文结论 : B 了解是否有疗法不含Z 但是口服 可以治疗感冒 : 结论是因为病毒在口鼻中分布不一样=>判断口服跟吸入的有效与否 : 那若是其他口服药物有效 这个连结就无效 =>影响结果 : D 是否Z或L 含有Z的效果 : 这个选项当时我是看了没什麽感觉啦 我自己判断是觉得无关结论 : 因为结论强调在分布的关系和口服吸入 感觉和是否有Z感觉无相关 事实是Z lozenges治疗感冒无效 而Z gel治疗感冒有效 前提是gel和lozenges所含的Z是一样的 结论是gel有效是因为病毒集中在鼻子而非嘴巴 B选项感觉有跳脱出这题题干的范围, 若是有其他疗法"不含Z"口服有效, 有效的原因有可能是其他疗法不含Z,这有点类似无关比较, 若成立则weaken 不成立呢? 也因为跳脱出Z的范围 无法佐证结论是否正确 D选项则是找出assumption中叙述的不完整部份, 若成立则weaken了结论 (两者成分不同对Z有影响) 不成立则填补了原文的不完整部份,等於support了结论 (增加前提:两者的成分对Z无影响) : 如果有错希望有人帮忙指正 : 这是我自己的感觉 如果有错也请帮忙指正 谢谢喔^^ --
