武汉大学出版社-经济法第七版课后思考题答案

第一章法调整经济关系的一般理论 1.简述物权和债权的主要区别 ①物权是直接支配权，不需要积极的义务主体。债权是请求权，有特定的积极的义务主体 ②物权是排他权，物权独一无二在同一物上，同一物上不能有诶容互不相容的物权。债权不具有排他性，同一物上可以有内容互不相容的多个债权。 ③物权的客体主要是物。物权是对所享有的权利。包括不动产和动产。债权的客体是行为——给付 ④物权是法定权，有法律规定债权可因法产生，也可因当事人约定产生 ⑤物权是优先权，物权优于一般债权。 2.简述相邻关系与地役权的主要区别 ①相邻关系产生具有无偿性，而地役权的设立一般是有偿的 ②设立方式不同：相邻关系是法定的且不需要通过登记程序：而地役权通常是由当事人通过合同约定设立 ③相邻关系不是一项民主权利，而地役权是一种用益物权。（物权的一种）

3.简述一般侵权行为与违约行为的主要区别 1.违约行为的基础是合同的存在，而侵权行为事先并不需要合同。 2.违约行为侵犯的是合同当事人对合同的预期利益，一般是财产利益；侵权行为侵犯的既有可能是对方财产权也有可能是人身权。 3.违约行为承担的责任后果仅限于财产侵害赔偿侵权行为的责任后果既包括财产侵害赔偿，也包括精神损害赔偿 4.违约责任是合同责任，诉讼时效2年；侵权责任的诉讼时效是自当事人知道侵权事由起的一年内。而根据产品质量法不合格产品致人损害的诉讼时效为两年 5.侵犯的权利不同：侵权行为所侵犯的是绝对物权违约行为所侵犯的是一种相对权 6.承担的责任不同：侵权——民事责任违约——违约责任 4.简述现代法律综合调整模式与古代法律综合调整模式的本质区别现代综合调整模式是建立在高度社会化的生产力和发达的现代市场经济基础上的更高级

计算机组成原理课后习题答案(常国锋武汉大学出版社)

第1 章习题参考答案 1?电子数字计算机和电子模拟计算机的区别在哪里？解：电子数字计算机中处理的信息是在时间上离散的数字量，运算的过程是不连续的；电子模拟计算机中处理的信息是连续变化的物理量，运算的过程是连续的。 2.冯?诺依曼计算机的特点是什么？其中最主要的一点是什么？解：冯?诺依曼计算机的特点如下： ①计算机（指硬件）应由运算器、存储器、控制器、输入设备和输出设备五大基本部件组成； ②计算机内部采用二进制来表示指令和数据； ③将编好的程序和原始数据事先存入存储器中，然后再启动计算机工作。第③ 点是最主要的一点。 3?计算机的硬件是由哪些部件组成的？它们各有哪些功能？解：计算机的硬件应由运算器、存储器、控制器、输入设备和输出设备五大基本部件组成。它们各自的功能是： ①输入设备：把人们编好的程序和原始数据送到计算机中去，并且将它们转换成计算机内部所能识别和接受的信息方式。 ②输出设备：将计算机的处理结果以人或其他设备所能接受的形式送出计算机。 ③存储器：用来存放程序和数据。 ④运算器：对信息进行处理和运算。 ⑤控制器：按照人们预先确定的操作步骤，控制整个计算机的各部件有条不紊地自动工作。 4?什么叫总线？简述单总线结构的特点。解：总线是一组能为多个部件服务的公共信息传送线路，它能分时地发送与接收各部件的信息。单总线结构即各大部件都连接在单一的一组总线上，这个总线被称为系统总线。C P U 与主存、C P U 与外设之间可以直接进行信息交换，主存与外设、外设与外设之间也可以直接进行信息交换，而无须经过 C P U 的干预。 5 ?简单描述计算机的层次结构，说明各层次的主要特点。解：现代计算机系统是一个硬件与软件组成的综合体，可以把它看成是按功能划分的多级层次结构。第0级为硬件组成的实体。第1 级是微程序级。这级的机器语言是微指令集，程序员用微指令编写的微程序一般是直接由硬件执行的。第2 级是传统机器级。这级的机器语言是该机的指令集，程序员用机器指令编写的程序可以由微程序进行解释。第3 级是操作系统级。从操作系统的基本功能来看，一方面它要直接管理传统机器中的软硬件资源，另一方面它又是传统机器的延伸。这级的机器语言是汇编语言，完成汇编语言翻译的程序叫做汇编程序。第5 级是高级语言级。高级语言翻译的工作。第6级是应用语言级。这级的机器语言就是各种高级语言，通常用编译程序来完成这一级是为了使计算机满足某种用途而专门设计的，因此这一级语言就是各种面向问题的应用语言。 6 .计算机系统的主要技术指标有哪些？解：计算机系统的主要技术指标有：机器字长、数据通路宽度、主存容量和运算速度等。机器字长是指参与运算的数的基本位数，它是由加法器、寄存器的位数决定的。数据通路宽度是指数据第4 级是汇编语言级。

Unit 1 PartⅡTextA One Writer's Beginnings 作家起步时我从两三岁起就知道，家中随便在哪个房间里，白天无论在什么时间，都可以念书或听人念书。母亲念书给我听。上午她都在那间大卧室里给我念，两人一起坐在她那把摇椅里，我们摇晃时，椅子发出有节奏的滴答声，好像有只唧唧鸣叫的蟋蟀在伴着读故事。冬日午后，她常在餐厅里烧着煤炭的炉火前给我念，布谷鸟自鸣钟发出“咕咕”声时，故事便结束了；晚上我在自己床上睡下后她也给我念。想必我是不让她有一刻清静。有时她在厨房里一边坐着搅制黄油一边给我念，故事情节就随着搅制黄油发出的抽抽搭搭的声响不断展开。我的奢望是她念我来搅拌；有一次她满足了我的愿望，可是我要听的故事她念完了，她要的黄油我却还没弄好。她念起故事来富有表情。比如，她念《穿靴子的猫》时，你就没法不相信她对猫一概怀疑。当我得知故事书原来是人写出来的，书本原来不是什么大自然的奇迹，不像草那样自生自长时，真是又震惊又失望。不过，姑且不论书本从何而来，我不记得自己有什么时候不爱书——书本本身、封面、装订、印着文字的书页，还有油墨味、那种沉甸甸的感觉，以及把书抱在怀里时那种将我征服、令我陶醉的感觉。还没识字，我就想读书了，一心想读所有的书。我的父母都不是来自那种买得起许多书的家庭。然而，虽然买书准得花去他不少薪金，作为一家成立不久的保险公司最年轻的职员，父亲一直在精心挑选、不断订购他和母亲认为儿童成长应读的书。他们购书首先是为了我们的前程。除了客厅里有一向被称作“图书室”的书橱，餐厅的窗子下还有几张摆放百科全书的桌子和一个字典架。这里有伴随我们在餐桌旁争论着长大的《韦氏大词典》、《哥伦比亚百科全书》、《康普顿插图百科全书》、《林肯资料文库》，以及后来的《知识库》。“图书馆”书橱里的书没过多久我就能读了——我的确读了，全都读了，按着顺序，一排接着一排读，从最上面的书架一直读到最下面的书架。母亲读书最重要的不在获取信息。她是为了享受快乐而埋头读小说。她读狄更斯时的神情简直就像要跟他私奔似的。她少女时代读的小说印在了她心头的，除了狄更斯、司各特和罗伯特?路易斯?斯蒂文森等人的作品之外，还有《简?爱》、《切尔比》、《白衣女士》、《绿厦》和《所罗门王的矿藏》。多亏了我的父母，我很早就接触了受人喜爱的马克?吐温。书橱里有一整套马克?吐温文集和一套不全的林?拉德纳作品集，这些书最终将父母和孩子联结在一起。我一本接一本阅读摆在我面前的书，读着读着便发现一本又破又旧的书，是我父亲小时候的。书名是《桑福徳与默顿》。我不相信如今还有谁会记得这本书。那是托玛斯?戴在18世纪80年代撰写的一本著名的进行道德教育的故事书，可该书的扉页上并没有提及他；上面写的是《桑福徳与默顿简易本》，玛丽?戈多尔芬著。书中讲的是一个富孩子和一个穷孩子与他们老师巴洛先生之间的冗长的谈话，其间穿插着戏剧性场面——分别写了富孩子和穷孩子如何发火、如何获救。书末讲的道德寓意不是一条，而是两条，都印在环形图案里：“不管发生什么，该做的就去做”，还有“想做伟人，必须先学会做个好人”。这本书没了封面，封底用几条纸片粘牢，有好几层，如今都泛黄了，书页上污迹斑斑，边角处都破碎了；书中花哨的插图脱了页，但都保存良好，夹在书里。即使在少不更事的童年，我就觉得那是我父亲小时候拥有的惟一一本书。他一直珍藏着这本书，或许还枕着这本没了封面的书睡觉：他7岁时就没了母亲。我父亲从来没跟自己的孩子提起过这本书，但他从俄亥俄一路把它带到我们的家，把它放进我们的书橱。

新一代大学英语综合教程 1 期末考试答案打印版 UNIT 1 .2、Indeed, we might feel as if we are suddenly awash in friends. Yet right before our eyes, we're also changing the way we conduct relationships. Face-to-face chatting is giving way to texting and messaging; people even prefer these electronic exchanges to, for instance, simply talking on a phone.Smaller circles of friends are being partially eclipsed by Facebook acquaintances routinely numbered in the hundreds. Amid these smaller trends, growing research suggests we could be entering a period of crisis for the entire concept of friendship. Where is all this leading modern-day society? Perhaps to a dark place, one where electronic stimuli slowly replace the joys of human contact.确实如此，我们似乎感到突然之间好友数量井喷。不过，我们眼前也正在改变为人处世的方式。面对面的聊天正在被短信取代；相比打个电话，人们甚至更愿意使用这些电子交流方式。脸谱网上的熟人圈儿动辄数百人，相比之下，现实生活中规模较小的朋友圈则显得黯淡少光。在这些较细微的趋势中，越来越多的研究表明友谊的整个概念正在遭受危机，而我们也许正在一步步地迈向这个危机时代。所有这一切要把现代社会引向何方？也许现代社会就此陷入黑暗深渊，在这个深渊里，人与人之间交往的乐趣慢慢地被电子诱惑所取代。 8、No single person is at fault, of course. The pressures on friendship today are broad. They arise from the demands of work, say, or a general busyness that means we have less quality time for others. How many individuals would say that friendship is the most important thing in their lives, only to move thousands of miles across the continent to take up a better-paid job?当然，这并不是某个人的错。如今，交友压力来自方方面面。比如来自工作压力，或是整天瞎忙，无法和他人享有高质量的沟通时间。有人嘴上说友谊是生命中最重要的东西，却为了一份收入颇丰的工作远赴千里之外。这样的人还少吗？ 9、Of course, we learn how to make friends —or not —in our most formative years, as children. Recent studies on childhood, and how the contemporary life of the child affects friendships, are illuminating. Again, the general mood is one of concern, and a central conclusion often reached relates to a lack of what is called "unstructured time."当然，我们是在性格成型的最重要的孩提时期学会如何结交朋友或是如何断交。最近，关于儿童期和儿时生活对交友的影响的研究很有启发性。这些研究再一次关注了风气这个问题，其主要结论都与孩子缺少―计划外时间‖有关。 10、Structured time results from the way an average day is parceled up for our kids — time for school, time for homework, time for music practice, even time for play. Yet too often today, no period is left unstructured. After all, who these days lets his child just wander off down the street? But that is precisely the kind of fallow time so vital for deeper friendships. It's then that we simply "hang out," with no tasks, no deadlines and no pressures. It is in those moments that children and adults alike can get to know others for who they are in themselves. ―计划内时间‖源自每一天的时间安排方式，何时上学，何时完成家庭作业，何时进行音乐训练，甚至何时玩耍，一股脑儿的塞给孩子。然而，再寻常不过的是，没有任何一个时段是没有安排的。毕竟，现在谁还会让自己的孩子在街上闲逛呢？但是，恰恰就是这种―无所事事‖的时间对于深厚的交情至关重要。在这个时间段，我们只是闲逛，没有任务，没有最后期限，没有任何压力。就在这些时候，孩子也罢，成人也罢，才能真正了解同行之人。 12、Aristotle had an attractive expression to capture the thought: close friends, he observed, "share salt together." It's not just that they sit together, passing the salt across the meal table. It's that they sit with one another across the course of their lives, sharing its savor — its moments, bitter and sweet. "The desire for friendship comes quickly; friendship does not," Aristotle also remarked. It's a key insight for an age of instant social connectivity, though one in which we paradoxically have an apparently growing need to be more deeply connected.亚里士多德曾经这样表达此意，妙不可言。他说，亲密的朋友，是―一起吃盐的朋友‖。他并不是说朋友们坐在一起，在饭桌上把盐传来传去。他的意思是朋友们共享人生经历，分享各种滋味，苦的，甜的。亚里士多德还说过―交友的想法常常匆匆而至，但是真正的友情往往姗姗来迟。‖这对于当今这个时代来说是一种重要的真知灼见。因为，在这个时代里，虽然人们能迅速建立关系，不过我们反倒越发觉得需要更深一步结识他人。 UNIT 26、With persistence and practice, such a process can lead to lasting results. I know one Wall Street executive who sought to improve his empathy –specifically his ability to read people’s reactions and their perspectives. Before beginning his quest, the executive’s subordinates were terrified of working with him. People even went so far as to hide bad news from him. Naturally, he was shocked when finally confronted with these facts. He went home and told his family – but they only confirmed what he had heard at work. When their opinions on any given subject did not mesh with his, they, too, were frightened of him.只要坚持并不断实践，这样的过程能够带来持久的结果。我认识一位华尔街的主管，他想方设法提高自己的同理心。具体一点就是读懂对方的反应，了解对方的看法。在开始努力寻求改变之前，这位主管的下属惧怕与其一起工作。人们甚至对他隐瞒坏消息。最终面对这些情况时，他自己自然大吃一惊。回家后，他告诉家人——但家人更肯定了他在单位听到的一切。无论什么话题，如果家人的观点未能与之吻合，他们也会害怕他。 7、Enlisting the help of a coach, the executive went to work to heighten his empathy through practice and feedback. His first step was to take a vacation to a foreign country where he did not speak the language. While there, he monitored his reactions to the unfamiliar and his openness to people who were different from him. When he returned home, humbled by his week abroad, the executive asked his coach to shadow him for parts of the day, Several times a week, in order to critique how he treated people with new or different perspectives. At the same time, he consciously used on-the-job interactions as opportunities to practice ―hearing‖ ideas that differed from his. Finally, the executive had himself videotaped in meetings and asked those who worked for and with him to critique his ability to acknowledge and understand the feelings of others. It took several months, but the executive’s emotional intelligence did ultimately rise, and the improvement was reflected in his overall performance on the job.这位主管向私人教师寻求帮助，他回到工作岗位，通过实践和别人的反馈来提高自己的同理心。首先，他到一个语言不通的国家去度假。在异国他乡，他审视自己面对不熟悉事物的反应以及对异族人群的开放性。返回家乡时，一周的国外生活已使他丢掉了所有的高傲，这位主管让私人教师一周跟踪自己几天，每天跟踪自己几个时段，以此评价自己对持新观点或不同观点人的态度。同时，他还有意识地利用工作现场与人交往的机会来实践―倾听‖异己观点。最后，主管还让人拍摄他开会时的表现，让下属以及合作伙伴评价自己承认并理解他人感情的能力。这个过程持续数月，但最终，主管的情商确实提高了，并在他的整体工作表现上体现了出来。 8 It’s important to emphasize that building one’s emotional intelligence cannot – will not – happen without sincere desire and concerted effort. A brief seminar won’t help; nor can one buy a how-to manual. It is much harder to learn to empathize –to internalize empathy as a natural response to people –than it is to become adept at regression analysis. But it can be done. ―Nothing great was ever achieved without enthusiasm,‖ wrote Ralph Waldo Emerson. If your goal is to become a real leader, these words can serve as a guidepost in your efforts to develop high emotional intelligence.需要强调的是，没有真诚的愿望和竭尽全力的付出，培养情商是不可能的，也不会有结果。一场简短的研讨会起不了作用，实用操作手册也无法买到。要使同理心内化为对别人的一种自然反应，才算是获得了同理心，这比擅于回归分析要难得多。但获得同理心也是能做到的。拉尔夫·沃尔多·爱默生写道：―没有热情，就不可能取得任何伟大的业绩。‖如果你的目标是成为一位真正的领袖，这句话可以激励你不断努力，提高情商。 UNIT 32、First, science is practiced by special people with a specific view of the world. Scientists try to be objective, unsentimental and unemotional. They do not let their feelings get in the way of their observations of real things, facts, as they call them. They often work in laboratories or in other areas where they can carefully control what they are working on. They do not just wander out onto the dock at sunset and look at the world with wonder, as a poet might. Ideally, they are also both honest and check them out and then utilize them in their findings so others can check them out and then utilize them in their own work. They do not claim more than they can prove, and often even less. But they are very proud of their calling and prefer to talk to other scientists rather than anybody else, especially poets, who tend to make them feel uncomfortable, to put them down.(Of course poets also feel scientists return the favor.)首先，从事科学工作的是特殊的一类人，他们具有特定的世界观。科学家努力保持客观、理性，不感情用事，不会让感情妨碍他们观察他们所说的实物和事实。科学家常常在实验室或者他们能够严格控制研究对象的场所工作。他们不会像诗人那样，在日落时去码头闲逛，惊奇地观赏这个世界。典型的科学家既朴实，又谦恭。他们总是尽量客观地汇报他们的科学发现，以便别人能够证实并在工作中加以运用。他们不会对自己不能证明的事物妄加断言，甚至常常连自己能够证明的也不去多说。然而，他们对―科学家‖这一称谓引以为傲，更喜欢彼此相互交流，而不太愿意和其他人交流，尤其是和诗人，因为诗人总让他们感觉不自在，且常贬低他们。（当然了，科学家在诗人眼里也不过如此。） 3、Second, science deals almost exclusively with things, not ideas or feelings, and with the external world and its workings, not inner states and their workings, despite the effort of some psychologists to be or seem scientific. The human body is considered to be or seem scientific. The human body is considered to be a part of the external world; the soul is not. Therefore, scientists work to understand the body but not the soul. Most scientists doubt the soul exists. The solar system and the universe are also part of the external world, although we have little enough direct evidence of their mode of existence. Scientists tend to assume the basic conditions of nature on Earth are the same everywhere in the cosmos.其次，科学的研究对象基本上仅限于事物，而非思想或者情感，仅限于外部世界及其运作，而非内在状态及其运作，尽管一些心理学家也试图让自己的工作具备或者显得有科学性。人体被认为是外部世界的一部分，而人的灵魂则不然。因此，科学家探索的是人的肌体，而不是灵魂。大部分科学家怀疑灵魂的存在。太阳系和宇宙也是外部世界的一部分，虽然我们没有充足的直接证据来证明它们的存在模式。科学家往往认为，地球上自然界的基本状况无论在宇宙的何处都是一样的。 4、Mankind is only questionably part of the external world in this sense. Scientists are generally reluctant to deal with the behavior of large groups of men and women. Thus economists, for example, struggle to be considered scientists, but usually in vain. The external world of scientists contains some things, like quanta, quarks and quasars, that are
