编辑点评： GRE写作需要大家积累一定的写作素材、锻炼自己的逻辑思维、多多积累一些有用的句子和词汇，有了这些基础以后，就需要大家根据真题来进行练习写作了。 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. 中文翻译： 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。 |
