2015年武汉大学考博英语真题试卷(题后含答案及解析)
2015年武汉大学考博英语真题试卷(题后含答案及解析)题型有：1. Reading Comprehension 2. English-Chinese Translation 3. Chinese-English Translation 4. WritingReading ComprehensionJustice in society must include both a fair trial to the accused and the selection of an appropriate punishment for those proven guilty. Because justice is regarded as one form of equality, we find in its earlier expressions the idea of a punishment equal to the crime. Recorded in the Old Testament is the expression: “ an eye for an eye, and a tooth for a tooth. “ That is, the individual who has done wrong has committed an offence against society. To make up for his offence, society must get even. This can be done only by doing an equal injury to him. This conception of retributive justice is refleeted in many parts of the legal documents and procedures of modern times. It is illustrated when we demand the death penalty for a person who had committed murder. This philosophy of punishment was supported by the German idealist Hegel. He believed that society owed it to the criminal to give a punishment equal to the crime he had committed. The criminal had by his own actions denied his true self and it is necessary to do something that will counteract this denial and restore the self that has been denied. To the murderer nothing less than giving up his own will pay his debt. The demand of the death penalty is a right the state owes the criminal and it should not deny him his due. Modern jurists have tried to replace retributive justice with the notion of corrective justice. The aim of the latter is not to abandon the concept of equality but to find a more adequate way to express it. It tries to preserve the idea of equal opportunity for each individual to realize me best that is in him. The criminal is regarded as being socially ill and in need of treatment that will enable him to become a normal member of society. Before a treatment can be administered, the course of his antisocial behavior must be found. If the cause can be removed, provisions must be made to have this done. Only those criminals who are incurable should be permanently separated from the rest of the society. This does not mean that criminals will escape punishment or be quickly returned to take up careers of crime. It means that justice is to heal the individual, not simply to get even with him. If severe punishment is the only adequate means for accompanying this, it should be administered. However, the individual should be given every opportunity to assume a normal place in society. His conviction of crime must not deprive him of the opportunity to make his way in the society of which he is a part.1．The best title for this passage in______.A．Fitting Punishment to the CrimeB．Approaches to Just PunishmentC．Improvement in Legal JusticeD．Attaining Justice in the Courts正确答案：B解析：本题为主旨题。
武大宇宙新概念试题二
第二学期《宇宙新概念》试题一．名词解释：每题5分，共20分。
1. 春分太阳在天球上从南向北移动，运行到天球赤道和黄道的交点，此时称为春分，是北半球春天的中点（分者半也，这一天为春季的一半，故叫春分）。
春分约发生在 3月20日或者3月21日，这一天时昼夜等长，故称为“分”。
简单的说；春分点与秋分点就是太阳直射地球赤道的那一刻。
2. 暗能量宇宙学中，暗能量[3]是某些人的猜想，指一种充溢空间的、具有负压强的能量。
在物理宇宙学中，暗能量是一种充溢空间的、增加宇宙膨胀速度的难以察觉的能量形式。
暗能量假说是当今对宇宙加速膨胀的观测结果的解释中最为流行的一种[1]。
在宇宙标准模型中，暗能量占据宇宙68.3%的质能。
3. 视星等视星等，是指观测者用肉眼所看到的星体亮度。
视星等的大小可以取负数，数值越小亮度越高，反之越暗。
晴朗的夜晚，点点繁星，有明有暗。
天文学家用“视星等”来区分它们的明亮程度。
整个天空肉眼能见到的大约有6000多颗恒星。
将肉眼可见的星分为6等。
肉眼刚能看到的定为6等星，比6等亮一些的为5等，依次类推，亮星为1等，更亮的为0等以至负的星等。
4. 类星体类星体是类似恒星天体的简称，又称为似星体、魁霎或类星射电源，与脉冲星、微波背景辐射和星际有机分子一道并称为20世纪60年代天文学“四大发现”。
二．简述题：每题15分，共30分。
1. 二十世纪60年代天文学的四大发现？星际分子、类星体、微波背景辐射和脉冲星1、星际分子：20世纪30年代,首先发现了第一种星际分子,接着又发现了两种.1963年,美国科学家发现星际羟基分子（OH）,此后,陆续发现大量星际有机分子.到80年代末,已发现了80多种,而且许多都是很复杂的有机分子,少数分子是地球上很难找到的或者根本找不到的.星际分子的发现有助于人类对星云特性的深入了解,可以帮助揭开生命起源的奥秘.2、类星体：第一颗类星体3C48是荷兰科学家施米时在1960年发现的.第二颗类星体3C273是在1963年发现的,这两个天体在外貌上看起来都像是颗恒星,从红移值比星系都大看来,它们根本不可能是恒星.这种类似恒星而又不是恒星的天体就被称为“类星体”.除了类星和巨大红移之外,类星体的又一主要特征是发射出的能量特别大.从60年代初到80年代初,总共发现了1500颗类星体.1982年,中国天文工作者何香涛创造性地改进了认证类星体的方法,一下就发现了500颗新类星体.3、1964年,美国贝尔电话实验室的彭齐亚斯和威尔逊为了检验一台巨型天线的低澡声性能,而把天线对准了没有明显天体的天区进行测量.他们发现,无论把天线指向何方,总能收到一定的噪声.后来发现噪声信号来自外部空间.科学家对这种微波辐射进行了比较分析.所谓辐射,就是电磁波,也就是光子气体.进一步的精确测量显示,这种辐射的温度相当于绝对温度3K的黑体辐射.由于这种辐射充满整个天球,形成了整个宇宙背景的辐射,所以称为3K宇宙微波背景辐射.它说明宇宙在200亿年前的大爆炸中,从高温致密态下脱胎出来.大爆炸的效应使得宇宙在不断膨胀,其密度不断变小,温度也逐渐下降.4、1967年,当时只有24岁的英国剑桥大学女研究生贝尔,和导师休伊什在狐狸座内发现了第一颗脉冲星.它是20世纪30年代就预言的中子星.所谓中子星,主要是由一种叫作中子的基本粒子组成超密恒星,它的直径只有10千米左右,自转特别快,周期性地发出脉冲.除此之外,脉冲星还具有许多独特的性质：(1)自转特别快,已发现的脉冲星周期都在0.002-4.3秒间,而且非常稳定；(2)密度特别大,1立方厘米可达1亿吨以上；(3)温度特别高,表面温度可达1000万摄氏度,相当于太阳中心温度的2/3,而其中心温度竟高达60亿摄氏度；(4)压力特别高,中心压力可达10000亿亿亿个大气压；(5)辐射特别强,是太阳的百万倍；(6)磁场特别强.到80年代末,已发现四五百颗脉冲星.2. 恒星的赫罗图的内涵是什么191l年在研究了银河系星团后他发表了昴星团和毕星团的颜色——星等图，即最早的赫罗图。

2015年高考英语真题分项解析：专题16+科普类说明文
专题十六阅读理解之科普类说明文1.【2015·湖北卷】DThe oddness of life in space never quite goes away. Here are some examples.First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. “I’m an inside guy,” Mike Hopkins says, who returned from a six-month tour on the International Spac e Station. “I like to be wrapped up.”On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it’s just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,”Your inner ear thinks your’re falling . Mean while your eyes are telling you you’re standing straight. That can be annoying—that’s why some people feel sick.” Within a couple days —truly terrible days for some —astronauts’ brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That’s why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.63.What is the major challenge to astronauts when they sleep in space?A. Deciding on a proper sleep positionB. Choosing a comfortable sleeping bagC. Seeking a way to fall asleep quicklyD. Finding a right time to go to sleep.64.The astronauts will suffer from a carbon-dioxide headache when _____.A. the y circle around on their bikesB. they use microcomputers without a stopC. they exercise in one place for a long timeD. they watch a movie while pedaling65.Some astronauts feel sick on the station during the first few days because _____.A. their senses stop workingB. they have to stand up straightC. they float out of their seats unexpectedlyD. whether they are able to go back to the station66.One of the NASA’s major concerns about astronauts is _____.A. how much exercise they do on the stationB. how they can remain healthy for long in spaceC. whether they can recover after returning homeD. whether they are able to go back to the station【解析】试题分析：这是一篇说明文。

引力子的结构和分布综述
内引力子云的密度都是由两物体的质量和 两物体的距离决定的。因此。万有引力的 大小就是由两物体的质量大小和两物体的 距离大小所决定的。具体的关系是：万有 引力的大小，与两个物体的乘积成正比，
第二种是在无引力子压存在的情况下，做ｌ 无规则的“热运动”，第三种是在引力子三｛ 态之间的交换运动，类似于物质的气、液、 固，三态之间分子的交换运动。
４．４说明 ４．４．１结合态、自由态、半自由态是相 对的，是相对于某一物体而言的。例如，在 天体附近存在相对于天体是半自由态的引 力子，若存在于这个天体附近或表面的宏 观物体内，则相对于这个物体是结合态；若 远离这个物体，则相对于这个物体是自由 态。 ４．４．２由于半自由态的引力子与物体的 引力较大，所以它能随物体一起运动。对 万有引力产生媒介作用的主要是半自由态 引力子。半自由态的厚度（范围大小）与 物体的质量成正比。 ４．４．３物体对引力子吸引力的大小，与 物体的质量成正比，与引力子离物体的距 离成反比。
