GRE官方题库原题133

A recent study reported that pet owners have longer, healthier lives on average than do people who own no pets. Specifically, dog owners tend to have a lower incidence of heart disease. In light of these findings, Sherwood Hospital should form a partnership with Sherwood Animal Shelter to institute an adopt-a-dog program. The program would encourage dog ownership for patients recovering from heart disease, which should reduce these patients' chance of experiencing continuing heart problems and also reduce their need for ongoing treatment. As a further benefit, the publicity about the program would encourage more people to adopt pets from the shelter. And that will reduce the incidence of heart disease in the general population.

Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.

题目翻译

一项最近的研究报告说养宠物的人平均而言比不养宠物的人活得更长更健康。特别是，养狗的人心脏病发病率更低。根据这些发现，Sherwood医院应该和Sherwood动物收养所合作建立一个"收养狗"的计划。这一计划将会鼓励正在治疗心脏病的患者养狗，这将通过减少这些患者接受治疗的次数而减少医疗费用。而且，对于这一计划的宣传将鼓励更多的人从收养所领养宠物，这将减少整体人群患心脏病的危险。

题目分析

1. 宠物与心脏病之间未必存在着因果联系。可能是身体好的人才养宠物，尤其是患心脏病的人往往无法养狗，所以才造成了养狗能治疗心脏病这个错误的因果关系。作者需要更多的证据来证明这个因果不是被倒置了。

2. 即使养狗能减少心脏病的发病，也未必能够治疗心脏病。因为预防与治疗是不同的，因此养狗对病人未必有益，可能养狗时的体力和精力的投入对病人的休养不是好事。因此作者需要更多的证据来证明养狗对心脏病治疗的功效。

3. 即使这项活动会成功，也未必能让更多的人为了减少心脏病患病率而去领养动物。因为除了有益健康，人们更倾向于从其他方面来考虑养动物的得失，包括时间、精力、费用和对动物本身的喜爱等，所以人们不一定愿意为了减少心脏病患病率而去领养宠物。
