单选题在四川的一些沼泽地中，剧毒的链蛇和一些无毒蛇一样，在蛇皮表面都有红白黑相问的鲜艳花纹。而就在离沼泽地不远的干燥地带，链蛇的花纹中没有了红色；奇怪的是，这些地区的无毒蛇的花纹中同样没有了红色。对这种现象的一个解释是，在上述沼泽和干燥地带中，无毒蛇为了保护自己，在进化过程中逐步变异为和链蛇具有相似的体表花纹。以下哪项最可能是上述解释所假设的?

单选题正确地度量服务部门工人的生产率很复杂。例如，考虑邮政工人的情况：如果每个邮政工人平均投递更多的信件，就称他们有更高的生产率。但这真的正确吗?如果投递更多信件的同时每个工人平均丢失或延迟更多的信件将会是什么情况呢? 以上对度量生产率的方法暗含的反对意见是基于对以下哪一项论述的怀疑? A．在计算生产率时可以适当地忽略提供服务的质量。 B．投递信件是邮政服务的主要活动。 C．生产率应归于工人所在的部门，而不是单个人。 D．邮政工人总是服务部门工人的代表。

单选题Manners nowadays in metropolitan cities like London are practically non-existent. It is nothing for a big, strong schoolboy to elbow an elderly woman aside in the dash for the last remaining seat on the tube or bus, much less stand up and offer his seat to her, as he ought. In fact, it is saddening to note that if a man does offer his seat to an older woman, it is nearly always a Continental man or one from the older generation. This question of giving up seats in public transport is much argued about by young men, who say that, since women have claimed equality, they no longer deserve to be treated with courtesy, and that those who go out to work should take their turn in the rat race like anyone else. Women have never claimed to be physically as strong as men. Even if it is not agreed, however, that young men should stand up for younger women, the fact remains that courtesy should be shown to the old, the sick and the burdened. Conditions in travel are really very hard on everyone, we know, but hardship is surely no excuse. Sometimes one wonders what would have been the behavior of these stout young men in a packed refugee train or a train on its way to a prisoner-camp during the war. Would they have considered it only right and their proper due to keep the best places for themselves then? Older people, tired and irritable from a day's work, are not angels, either--far from it. Many a brisk argument or an insulting quarrel breaks out as the weary queues push and shove each other to get on buses and tubes. One cannot commend this, of course, but one does feel there is just a little more excuse. If cities are to remain pleasant places to live in at all, however, it seems urgent, not only that communications in transport should be improved, but also that communication between human beings should be kept smooth and polite. All over cities, it seems that people are too tired and too rushed to be polite. Shop assistants won't bother to assist, taxi drivers shout at each other as they dash dangerously round corners, bus conductors pull the bell before their desperate passengers have had time to get on or off the bus, and so on and so on. It seems to us that it is up to the young and strong to do their small part to stop such deterioration.

单选题生活应该是一系列冒险，它很有乐趣，偶尔让人感到兴奋，有时却好像是通向不可预知未来的痛苦旅程。当你试图以一种创造性的方式生活时，即使你身处沙漠中，也会遇到灵感之井、妙想之泉，它们却不是能事先拥有的。 下面哪一个选项所强调的意思与题干的主旨相同? A．英国哲学家休谟说，习惯是人生的伟大指南。 B．美国哲学家怀特海说，观念的改变损失最小，成就最大。 C．法国化学家巴斯德说，机遇只偏爱有准备的头脑。 D．美国诗人弗罗斯特说，假如我知道写诗的结果，我就不会开始写诗。

单选题棕榈树在亚洲是一种外来树种，长期以来，它一直靠人工授粉，因此棕榈果的生产率极低。1994年，一种能有效地对棕榈花进行授粉的象鼻虫被引进了亚洲，使得当年的棕榈果生产率显著提高，在有的地方甚至提高了50%以上，但是到了1998年，棕榈果的生产率却大幅度降低。 以下哪项如果为真，最有助于解释上述现象?______

单选题是否公开学生的学习成绩，已成为明讯管理学院的一个热点话题。很多学生认为学习成绩是个人隐私，应该得到保护，呼吁学院不要再公开发布学生的学习成绩。学院的管理部门经过慎重的考虑，决定今后所有的学习成绩统一通过电子函件的方式发送，每个学生将只能收到自己的学习成绩。 以下各项为得知学院的这个决定后大家的一些反馈意见，其中哪项最能让学院的管理部门重新思考或修正他们的决定?______

单选题只有糖化血红蛋白指标控制在6以下，尿中的微量白蛋白才能控制在20mg/L～200mg/L范围内。 以下各项都符合题干的条件，除了?

单选题一般人总会这样认为，既然人工智能这门新兴学科是以模拟人的思维为目标的，那么就应该深入地研究人思维的生理机制和心理机制。其实，这种看法很可能误导这门新兴学科。如果说，飞机发明的最早灵感是来自于鸟的飞行原理的话，那么，现代飞机从发明、设计、制造到不断改进，没有哪一项是基于对鸟的研究之上的。上述议论，最可能把人工智能的研究比作以下哪项?

单选题和十年前相比，苏格兰人的年人均食物摄入量增加了大约80公斤。这部分地冈为和十年前相比，15至64岁之间年龄段的人口所占的比例有了显著提高。从以上叙述能得出以下哪项结论?

单选题在丈夫或妻子至少有一个是中国人的夫妻中，中国女性比中国男性多2万。如果上述断定为真，则以下哪项一定为真？Ⅰ．恰有2万中国女性嫁给了外国人。Ⅱ．在和中国人结婚的外国人中，男性多于女性。Ⅲ．在和中国人结婚的人中，男性多于女性。

单选题乙醇属于可再生能源，是由高粱、玉米薯类等经过发酵而制得的。它不影响汽车的行驶性能，还减少有害气体的排放量。乙醇汽油作为一种新型清洁燃料，是目前世界上可再生能源的发展重点，符合我国能源替代战略和可再生能源发展方向，技术上成熟安全可靠，在我国完全适用，具有较好的经济效益和社会效益。乙醇汽油是一种混合物而不是新型化合物。在汽油中加入适量乙醇作为汽车燃料，可节省石油资源，减少汽车尾气对空气的污染，还可促进农业的生产。以汽车日流量超过600万辆的北京为例，如果所有汽车都使用汽油酒精，那么每天产生的二氧化碳不比北京的绿色植被通过光合作用吸收的多。因此，可以预计，在世界范围内，汽油酒精将很快进军并占领汽车燃料市场。 以下各项如果为真，都能加强题干论证，除了?

单选题一种在儿童中非常流行的病毒感染导致30%被感染的儿童患了中耳炎，对细菌感染非常有效的抗生素对这种病毒却无能为力。然而，当因病毒感染而患中耳炎的儿童接受抗生素治疗后，中耳炎却得到了治愈。 以下哪一项最好地解释了上文中明显的不一致?

单选题借债者的信用等级越低，其借债的成本越高，债主的收益率也越高。2011年8月5日，标普将美国主权信用评级从AAA将为AA+。按照常理，投资者出于避险需求应当减持美国国债，从而推动其价格走低，收益率上升。然而，8月8日美国国债价格上涨，收益率降低，最新10年期美国国债收益率降至2.34%，创今年以来新低。 如果以下哪项陈述为真，能够最好地解释上述违反常理的现象? A．8月5日晚间，美国财政部回应称，标普进行评级计算时有2万亿美元的误差。 B．美国主权信用评级下调后，俄罗斯开始减持美国国债，而中国仍增持美国国债。 C．欧盟为打破标普等三家美国评级机构的垄断地位，计划建立一家欧洲的信用评级机构。 D．与欧盟、日本以及其他国家的债券相比，美国国债依然是相对安全和流动性最高的投资品。

单选题For me, scientific knowledge is divided into mathematical sciences, natural sciences or sciences dealing with the natural world (physical and biological sciences), and sciences dealing with mankind (psychology, sociology, all the sciences of cultural achievements, every kind of historical knowledge). Apart from these sciences is philosophy, about which we will talk later. In the first place, all this is pure of theoretical knowledge, sought only for the purpose of understanding, in order to fulfil the need to understand what is intrinsic and consubstantial to man. What distinguishes man from animal is that he knows and needs to know. If man did not know that the world existed, and that the world was of a certain kind, that he was in the world and that he himself was of a certain kind, he wouldn't be man. The technical aspects or applications of knowledge are equally necessary for man and are of the greatest importance because they also contribute to defining him as man and permit him to pursue a life increasingly more truly human. But even while enjoying the results of technical progress, he must defend the primacy and autonomy of pure knowledge. Knowledge sought directly for its practical applications will have immediate and foreseeable success, but not the kind of important result whose revolutionary scope is in large part unforeseen, except by the imagination of the Utopians. Let me recall a well-known example. If the Greek mathematicians had not applied themselves to the investigation of conic sections, zealously and without the least suspicion that it might someday be useful, it would not have been possible centuries later to navigate far from shore. The first man to study nature of electricity could not imagine that' their experiments, carried on because of mere intellectual curiosity, would eventually lead to modern electrical technology, without which we can scarcely conceive of contemporary life. Pure knowledge is valuable for its own sake, because the human spirit cannot resign itself to ignorance. But, in addition, it is the foundation for practical results that would not have been reached if this knowledge had not been sought disinterestedly.
