GRE官方题库原题103
The following appeared in a memorandum from the planning department of an electric power company.
"Several recent surveys indicate that home owners are increasingly eager to conserve energy. At the same time, manufacturers are now marketing many home appliances, such as refrigerators and air conditioners, that are almost twice as energy efficient as those sold a decade ago. Also, new technologies for better home insulation and passive solar heating are readily available to reduce the energy needed for home heating. Therefore, the total demand for electricity in our area will not increase—and may decline slightly. Since our three electric generating plants in operation for the past twenty years have always met our needs, construction of new generating plants will not be necessary."
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
一些最近的调查表明,房主越来越强烈地希望节省能源,并且生产商现在正在推出很多比十年前的电器几乎节能两倍的家用电器,比如冰箱和空调,这些电器要比10前出售的节能50%。而且,更好的房屋隔热和被动式太阳能采暖的新技术已经可以用于减少家庭采暖所需的能源。因此,我们预计我们地区的用电需求总量不会增加,而可能有轻微下降。由于我们的已经运作了20年的三座发电站总能够满足需求,我们无需建造新的发电厂。
题目分析
1. 作者并没有提到样本的选择,因此调查的结论未必可信。第一,作者没有提到样本的数量,因此调查结果未必能反映大多数人的想法;第二,作者没有提到样本的组成,因此调查结果未必能正确反映群众的想法。
2. 即使作者列举的三个例子都正确,也无法推知总的电力需求会下降的结论。第一,某些家用电器和供暖费用等,只是民用电力需求的一部分,诸如电子产品的耗能等并未考虑在内;第二,即使民用需求下降,工业的需求也可能上升,从而导致总需求上升。
3. 即使当地需求下降,也可能需要新的发电厂。因为有其他因素左右发电厂的建造。比如需要给其他地区输送电能,或者是新的发电厂会采用更环保的工艺,为了淘汰其他的两家发电厂等。
