| 第1题：One of the questions that is coming into focus as we face growing scarcity of resources of many kinds in the world is how to divide limited resources among countries. In the international development community, the conventional wisdom has been that the 2 billion people living in poor countries could never expect to reach the standard of living that most of us in NorthAmerica enjoy, simply because the world does not contain enough iron ore, protein, petroleum, and so on.At the same time, we in the United States have continued to pursue super affluence as though there were no limits on how much we could consume. We make up 6 percent of the world’s people; yet we consume one-third of the world’s resources. As long as the resources we consumed each year came primarily from within our own boundaries, this was largely an internal matter.But as our resources come more and more from the outside world, "outsiders" are going to have some say over the rate at which and terms under which we consume. We will no longer be able to think in terms of "our" resources and "their" resources, but only of common resources. AsAmericans consuming such a disproportionate share of the world’s resources, we have to question whether or not we can continue our pursuit of super affluence in a world of scarcity. We are now reaching the point where we must carefully examine’ the presumed link between our level of well-being and the level of material goods consumeD、If you have only one crust of bread and get another crust of bread, your well-being is greatly enhanceD、But if you have a loaf of bread, then an additional crust of bread doesn’t make that much difference. In the eyes of most of the world today,Americans have their loaf of bread and are asking for still more. People elsewhere are beginning to ask why. This is the question we’re going to have to answer, whether we’re trying to persuade countries to step up their exports of oil to us or trying to convince them that we ought to be permitted to maintain our share of the world fish catch. The prospect of a scarcity of, and competition for, the world’s resources requires that we reexamine the way in which we relate to the rest of the worlD、It means we find ways of cutting back on resource consumption that is dependent on the resources and cooperation of other countries. We cannot expect people in these countries to concern themselves with our worsening energy and food shortages unless we demonstrate some concern for the hunger, illiteracy and disease that are diminishing life for them. What is the conclusion of this passage A、The United States will be isolated if it does not stop pursuing super affluence. B、The poor countries will no longer supply the United States with their goods. C、The United States should care about the well-being of other countries. D、It is time for theAmericans to help the people in poor countries to improve their living standards. |

| 第2题：一盎司与一盎司相比，不同的人工增甜剂的混合物和单一的人工增甜剂的增甜强度是一样的。当用来使食物变甜时，混合物极大地降低了消费者摄入过量的单一增甜剂的可能性。因此，应该使用混合的而不是单一的人工增甜剂，因为混合物明显地是更健康的而且有同样的效果。 以下哪项，最可能是上述论证所依赖的假设 A、当混合物中的不同人工增甜剂一起被消化时，不会产生交叉作用以至于对健康有害。 B、不同的人工增甜剂所给定的日摄入量都是一个保守数字，即使超过这一数字也不会有危险。 C、任何一种人工增甜剂所给定的日摄入量都是一个保守数字，即使超过这一数字也不会有危险。 D、在饮食中用人工增甜剂代替食糖的消费者通常会记录他们每日对不同增甜剂的摄入量。 E、过量摄入任何一种单一的人工增甜剂对健康造成的危害不能通过以后摄入量的减少来消除。 |

| 第3题：由于外科医生的数量比手术数量增加得快，同时，由于不开刀的药物治疗越来越多地代替外科手术，近年来每个外科医生的年平均手术量下降了1/4。因此，如果这种趋势持续下去，外科医生水平就会发生大幅度下降。 以下哪项是上述论证所必需假设的 A．一个外科医生医术水平不可能适当地保持下去，除非他以一定的最小频率作手术。 B．外科医生现在将他们的大部分时间用在完成不用开刀的药物治疗工作上。 C．所有的医生，尤其是外科医生，在医学院所接受的训练比前些年差多了。 D．每一个外科医生本人的医术水平近年来都有所下降。 E．(E) 某些经验丰富的外科医生目前所做的手术比他们通常所做的量大得多。 |

| 第5题：It is just one example of the growing concern over the increasing power consumption and environmental impact of computers. A、study found that the power consumption of data centers doubled between 2000 and 2005, and now accounts for 1.2% ofAmerican electricity consumption, though other estimates put the figure at 4%.Companies now spend as much as 10% of their technology budgets on energy, says Rakesh Kumar of Gartner, a consultancy. Power consumption has increased because of the rise of the internet, of course, but also because of way in which computers have historically been designed: to maximize performance at all costs.Between 1996 and 2006, the number of servers in use went from 6 million to 28 million and the average power consumption of each server grew from 150 watts to 400 watts.But things are now starting to change and the computer industry has been seized with enthusiasm for "green computing". |

| 第6题：每年科学家都统计在主要繁殖地聚集的金蟾蜍的数量。在过去十年中，每年聚集在那里的金蟾蜍的数量从1500只下降到200只。显然，在过去的十年中，金蟾蜍的数量在急剧下降。 以下哪项如果为真，能使上文中的结论适当地得出
A．在过去的十年间，对某些次要的繁殖地所聚集的金蟾蜍的数量也统计过。 B．每年在主要繁殖地聚集的金蟾蜍的数量在全部金蟾蜍中所占的比例相同。 C．统计在主要繁殖地聚集的金蟾蜍数量的科学家也对其他种类两栖动物的数量是否有所下降做了考察。 D．聚集在主要繁殖地的金蟾蜍的总体比例在不同的年份中有时会有显著的差异。 E．在某些次要的繁殖地，晚于在主要繁殖地孵化出的金蟾蜍的数量所占的比例不大。 |

| 第7题：建筑历史学家丹尼斯教授对欧洲19世纪早期铺有木地板的房子进行了研究。结果发现较大的房间铺设的木板条比较小房间的木板条窄得多。丹尼斯教授认为，既然大房子的主人一般都比小房子的主人富有，那么，用窄木条铺地板很可能是当时有地位的象征，以表明房主的富有。 以下哪项如果为真，最能加强丹尼斯教授的观点
A．欧洲19世纪晚期的大多数房子所铺设的木地板的宽度大致相同。 B．丹尼斯教授的学术地位得到了国际建筑历史学界的公认。 C．欧洲19世纪早期，木地板条的价格是以长度为标准计算的。 D．欧洲19世纪早期，有些大房子铺设的是比木地板昂贵得多的大理石。 E．在以欧洲19世纪市民生活为背景的小说《雾都十三夜》中，富商查理的别墅中铺设的就是有别于民间的细条胡桃木地板。 |

| 第8题：在国庆50周年仪仗队的训练营地，某连队一百多个战士在练习不同队形的转换。如果他们排成五列人数相等的横队，只剩下连长在队伍前面喊口令；如果他们排成七列这样的横队，只有连长仍然可以在前面领队；如果他们排成八列，就可以有两人作为领队了。在全营排练时，营长要求他们排成三列横队。 以下哪项是最可能出现的情况 A．该连队官兵正好排成三列横队。 B．除了连长外，正好排成三列横队。 C．排成了整齐的三列横队，另有两人作为全营的领队。 D．排成了整齐的三列横队，其中有一人是其他连队的。 E．排成了三列横队，连长在队外喊口令，但营长临时排在队中。 |

| 第10题：生长在大豆或其他豆类植物根部的根瘤菌能产生固态氮，这是如小麦等其他非豆类庄稼生长不可缺少的植物营养之一，通常它们必须从人造氮肥中得到供给。所以，如果生物技术能成功地使小麦的根部也成为根瘤菌的寄生地，就会减少对人造肥料的需求。 上述论证做了以下哪项假设 A、这种生物技术使小麦根部所产生的根瘤菌必须与豆类植物根部的根瘤菌属于相同的种类。 B、对小麦生长的土壤来说，固态氮是目前必须靠人工肥料来提供的唯一养料。 C、小麦和其他植物根部的根瘤菌寄生地没有天然形成的。 D、豆类植物是目前唯一能自己生产其所需要的固态氮的农作物。 E、生存在小麦根部的根瘤菌将会产生固态氮。 |
