2006年`12月
四、翻译下面一段文章（15分）
参考答案：
马就是这种东西，它的蹄子可以用来踏冰雪，马毛可以抵御风与严寒，吃草，喝水，这些就是马的真性情了。
虽然人建造了义台、路寝那些高大宏伟的建筑，对马来说是完全无用的。
到世间出了伯乐，他说：“我擅长于治理（驯）马匹。
”在马的身上有些地方烧，有些地方剜，有些地方用刀刻，有些部分用火烫，然后给马套上缰绳，把它们绑在马槽边。
经过这一番折腾，马已经死掉十分之二三了。
再让剩下的马挨饿，受渴，让它们奔跑、跳跃，让它们排队站齐，嘴上绑着横木，后面拿皮鞭竹条追打威胁，这一来马已死掉一半多了。
陶工说：“我擅长治理粘土。
我做出来的东西，圆的合于圆规，直的合乎尺子（的度量）。
”木匠说：“我擅长治理木头，折线的地方跟钩弧角度一样，直边就跟用墨线量出来的一样。
”但是，粘土、树木的本性，难道是愿意合乎圆规、尺子、钩弧、墨线的吗！然而人们世世代代称颂这些人，并且说：“伯乐最善驯马，陶工和木匠最善于治理粘土和木头。
（加工陶器和木器）”这些也是那些所谓最善于治理天下的人的过错啊。

2006年国家公务员考试真题及答案
2006年中央、国家机关公务员录用考试《行政职业能力测验（B）》试卷第一部分言语理解与表达每道题包含一段文字或一个句子，后面是一个不完整的陈述，要求你从四个选项中选出一个来完成陈述。
注意：答案可能是完成对所给文字主要意思的提要，也可能是满足陈述中其他方面的要求，你的选择应与所提要求最相符合。
1．幽默使人如沐春风，也能解除尴尬。
一个懂得幽默的人，会知道如何化解眼前的障碍。
我们有时无意中让紧张代替了轻松，让严肃代替了平易，一不小心就变成了无趣的人。
对这段话，理解不准确的是：（）A．紧张的生活需要幽默调剂 B．许多人在生活中不擅长使用幽默C．生活中，幽默可以化解许多难堪 D．有情趣的生活，是因为有了幽默【解析】D。
材料主要谈的是幽默的作用，A、B、C答案都是材料内容的体现；幽默可以化解障碍，甚至增加生活情趣，但并不能反推出“有情趣的生活，是因为有了幽默”，所以D不正确。
2．有时候律师的辩护很可能开脱了凶手，有损公共道德，但他们“完美”的法律服务没错。
因为法治之法是中性的，它超越道德；而“平等对抗”的诉讼程序，须保证被告人享有他所购买的一切法律服务。
即使被告人真是凶手，律师帮他胜诉获释，正义受挫，从法制或“程序之治”的长远利益来看，这也还是值得的，失败了的正义可以在本案之外。
对这段话的正确理解是：（）A．法制与道德是相互对立的B．在一个单一的案件中找不到正义C．维护法制程序的意义大于一时的伸张正义D．为了保证法制程序的实施，律师常常不得已而为之【解析】C。
此题关键在于最后一句话，从“即使被告人真是凶手，律师帮他胜诉获释，正义受挫，从法制或‘程序之治’的长远利益来看，这也还是值得的，失败了的正义可以在本案之外”可以看出维护法律程序的意义大于一时的伸张正义。
3．时代的场景变化太大了，要让年轻一代真正记住历史，不能停留在概念式的说教上。
真正完整有效的历史教育，是应当融会在生活之中的。

For each of them there are four choices m arked A) , B) , C) and D). You should decide on the best choice and mark the co rresponding letter on the Answer Sheet with a single line through the center.Questions 21 to 25 are based on the following passage:Interest in pursuing international careers has soared in recent years. enhanced by chronic (长久的) personnel shortages that are causing companies to search b eyond their home borders for talent.Professionals seek career experience outside of their home countries for a vari ety of reasons. They may feel the need to recharge their batteries with a new chal lenge. They may want a position with more responsibility that encourages creativity and initiative. Or they may wish to expose their children to another culture, and th e opportunity to learn a second language.When applying for a job, one usually has to submit a resume or curriculum vit ae (CV). The two terms generally mean the same thing: a one- or two-page docu ment describing one's educational qualifications and professional experience. Howev er, guidelines for preparing a r6sum6 are constantly changing. The best advice is t o find out what is appropriate regarding the corporate (公司) culture, the country cu lture, and the culture of the person making the hiring decision. The challenge will b e to embrace two or more cultures in one document. The following list is a good p lace to start.● "Educational requirements differ from country to country. In almost every case of 'cross- border' job hunting, just stating the title of your degree will not bean adequate description. Provide the reader with details about your studies and any rel ated experience. " daohangtigong● Pay attention to the resume format you use-chronological or reverse-chronolo gical order. Chronological order means listing your 'oldest' work experience first. Re verse-chronological order means listing your current or most recent experience first. Most countries have preferences about which format is most acceptable. If you fin d no specific guidelines. the general preference is for the reverse-chronological for mat. "● If you are submitting your resume in English, find out if the recipient （收件人) uses British English or American English because there are variations between the two versions. For example, university education is often referred to as 'tertiary education' in the United Kingdom, but this term is almost never used in the United States. A reader who is unfamiliar with these variations may assume that your res ume contains errors.21. Companies are hiring more foreign employees becauseA) they find foreign employees are usually more talentedB) they need original ideas from employees hired overseasC) they want to expand their business beyond home bordersD) they have difficulty finding qualified personnel at home22. The author believes that an individual who applies to work overseasA) is usually creative and full of initiativeB) aims to improve his foreign language skillsC) is dissatisfied with his own life at homeD) seeks either his own or his children's development23. When it comes to resume writing, it is best toA) take cultural factors into considerationB) learn about the company's hiring processC) follow appropriate guidelines for job huntingD) know the employer's personal likes and dislikes24. When writing about qualifications, applicants are advised toA) stress their academic potential to impress the decision makerB) give the title of the university degree they have earned at homeC) provide a detailed description of their study and work experiencesD) highlight their keen interest in pursuing a 'cross-border' career25. According to the author's last piece of advice, the applicants should be aw are ofA) the different educational systems in the US and the UKB) the differences between the varieties of EnglishC) the recipient's preference with regard to the formatD) the distinctive features of American and British culturesQuestions 26 to 30 are based on the following passage:北京导航李勇全、郑景婷、王轶群提供Educating girls quite possibly yields a higher rate of return than any other inve stment available in the developing world. Women's education may be unusual territ ory for economists, but enhancing women's contribution to development is actuallyas much an economic as a social issue. And economics, with its emphasis on ince ntives (激励), provides guideposts that point to an explanation for why so many girl s are deprived of an education.Parents in low-income countries fail to invest in their daughters because they d o not expect them to make an economic contribution to the family: girls grow up o nly to marry into somebody else's family and bear children. Girls are thus seen as less valuable than boys and art kept at home to do housework while their brother s are sent to school - the prophecy （预言) becomes self- fulfilling, trapping women in a vicious circle (恶性循环) of neglect.An educated mother, on the other hand, has greater earning abilities outside th e home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children, ensurin g that her daughters are given a fair chance. The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys, wi ll be educated and healthy. The vicious circle is thus transformed into a virtuous ci rcle.Few will dispute that educating women has great social benefits. But it has en ormous economic advantages as well. Most obviously, there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 per cent for e ach additional year of schooling. Such big returns are impressive by the standard o f other available investments, but they are just the beginning. Educating women als o has a significant impact on health practices, including family planning.26. The author argues that educating girls in developing countries isA) troublesome C) rewardingB) labor-saving D) expensive27. By saying "... the prophecy becomes self-fulfilling ..." (Lines 45. Para. 2). t he author means thatA) girls will turn out to be less valuable than boysB) girls will be capable of realizing their own dreamsC) girls will eventually find their goals in life beyond reachD) girls will be increasingly discontented with their life at home28. The author believes that a vicious circle can turn into a virtuous circle whe nA) women care more about educationB) girls can gain equal access to educationC) a family has fewer but healthier childrenD) parents can afford their daughters' education29. What does the author say about women's education?A) It deserves greater attention than other social issues.B) It is now given top priority in many developing countries.C) It will yield greater returns than other known investments.D) It has aroused the interest of a growing number of economists.30. 7be passage mainly discussesA) unequal treatment of boys and girls in developing countriesB) the potential earning power of well-educated womenC) the major contributions of educated women to societyD) the economic and social benefits of educating womenPassage Three北京导航李勇全、郑景婷、王轶群提供Questions 31 to 35 are based on the following passage:Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in for an unwelcome surprise. The car is fitted with a remote immobiliser (锁止器), and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again.The idea goes like this. A control box fitted to the car contains a mini-cellphon e, a micro- processor and memory, and a GPS (全球定位系统) satellite positioning receiver. ff the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being rest arted. daoahngtigongIn the UK, a set of technical fixes is already making life harder for car thieves. 'The pattern of vehicle crime has changed,' says Martyn Randall, a security expert. He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old.Modern cars are far tougher to steal, as their engine management computer w on't allow them to start unless they receive a unique ID code beamed out by the i gnition (点火) key. In the UK, technologies like this have helped achieve a 31% dr op in vehicle-related crime since 1997.But determined criminals are still managing to find other ways to steal cars, oft en by getting bold of the owner's keys. And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system.If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen. The hundred me tres minimum avoids false alarms due to inaccuracies in the GPS signal.Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle's movements via the car's GPS u nit.31. What's the function of the remote immobilizer fitted to a car?A) To help the police make a surprise attack on the car thief.B) To allow the car to lock automatically when stolen.C) To prevent the car thief from restarting it once it stops.D) To prevent car theft by sending a radio signal to the car owner.32. By saying 'The pattern of vehicle crime has changed' (Lines 1-2. Para. 3). Martyn Randall suggests thatA) it takes a longer time for the car thief to do the stealingB) self-prepared tools are no longer enough for car theftC) the thief has to make use of computer technologyD) the thief has lost interest in stealing cars over 10 years old33. What is essential in making a modem car tougher to steal?A) A coded ignition key. C) A special cellphone signal.B) A unique ID card. D) A GPS satellite positioning receiver.34. Why does the tracking system set a 100-metre minimum before sending a n alarm to the operations centre?A) To leave time for the operations centre to give an alarm.B) To keep police informed of the car's movements.C) To give the driver time to contact the operations centre.D) To allow for possible errors in the GPS system.35. What will the operations centre do first after receiving an alarm?A) Start the tracking system. C) Block the car engine.B) Contact the car owner. D) Locate the missing car.Passage Four北京导航李勇全、郑景婷、王轶群提供Questions 36 to 40 are based on the following passage:Psychiatrists 精神病专家) who work with older parents say that maturity can be an asset in child rearing - older parents are more thoughtful, use less physical dis cipline and spend more time with their children. But raising kids takes money and energy. Many older parents find themselves balancing their limited financial resourc es, declining energy and failing health against the growing demands of an active c hild. Dying and leaving young children is probably the older parents' biggest, and o ften unspoken, fear. Having late-life children, says an economics professor. often m eans parents, particularly fathers, "end up retiring much later." For many, retirement becomes an unobtainable dream.Henry Metcalf. a 54-year-old journalist, knows it takes money to raise kids. But he's also worried that his energy will give out first. Sure, he can still ride bikes wi th his athletic fifth grader, but he's learned that young at heart doesn't mean young. Lately he's been taking afternoon naps (午睡) daohang to keep up his energy. "M y body is aging," says Metcalf. "You can't get away from that."Often, older parents hear the ticking of another kind of biological clock. Therapi sts who work with middle-aged and older parents say fears about aging are nothin g to laugh at. "They worry they'll be mistaken for grandparents, or that they'll need help getting up out of those little chairs in nursery school," says Joann Galst, a N ew York psychologist. But at the core of those little fears there is often a much bigger one: "that they won't be alive long enough to support and protect their child," she says.Many late-life parents, though, say their children came at just the right time. Af ter marrying late and undergoing years of fertilily (受孕) treatment, Marilyn Nolen a nd her husband. Randy, had twins. "We both wanted children," says Marilyn, who was 55 when she gave birth. The twins have given the couple what they desired f or years, "a sense of family." Kids of older dads are often smarter, happier and m ore sociable because their fathers are more involved in their lives. 'The dads are o lder, more mature," says Dr. Silber, "and more ready to focus on parenting."36.

2006年河南省专升本管理学B卷参考答案
2006年河南省专升本管理学B卷参考答案特别注意：以下参考答案是根据今年参加专升本考生对试题的整理，由相关高校管理学教师共同给出相应答案，答案仅供考生参考估分，权威答案及评分标准要以政府改卷为准。
四、简答题46. 答：管理就是在特定的环境下，对组织所拥有的资源进行有效的计划、组织、领导和控制，以便达成既定的组织目标的过程。
管理的性质主要表现在以下三个方面：（1）管理的二重性。
自然属性和社会属性。
一方面，管理是生产社会化引起的，具有同生产力和社会化大生产相联系的自然属性；另一方面，管理同生产关系、社会制度相联系，具有社会属性。
（2）管理的科学性。
管理是一门科学，这是强调其客观规律性。
管理作为一个活动过程，其间存在着一系列基本的客观规律，要用科学的方法论来分析问题和解决问题。
（3）管理的艺术性。
管理是一种艺术，这是强调管理的实践性。
它强调管理活动除了要掌握一定的理论和方法外，还要有灵活地运用这些知识和技能的技巧和诀窍。
47. 领导方式的统一体理论是由坦南鲍姆和施米特提出的。
他们认为专制和放任是领导行为方式的两个极端，在此之间还存在许多领导行为，这些行为构成了领导行为的连续统一体。
领导方式的统一体理论描述了主要以领导为中心到主要以下属为中心的领导方式转变过程，很好地说明了领导风格的多样性和方式因情况而变化的性质。
他们把领导行为分成了七种模式，应考虑三方面的内容（即领导方面的条件、下属方面的条件、组织环境方面的条件）来决定采取哪种领导方式。
48.决策就是管理者（1分）识别并解决问题以及利用机会（1分）的过程（1分）。
特征为：（1）目标性：决策是有意识，有目的的活动；任何决策都包含着目标的确定，目标体现的是组织想要获得的结果。
（2）可行性：每个决策的方案都有一定的可行性。
决策所做的若干个备选方案应是可行的，这样才能保证决策方案切实可行。
（3）选择性：决策的实质是选择。
决策是多种方案的选择；决策的关键是选择，没有选择就没有决策。
