三、判断题。本大题共5个小题，每小题 4.0 分，共20.0分。
以下五道判断题均围绕下面文章展开：
The workers who brought the girl to the orphanage knew little about her.
The streets where they found her had been her home for many years. Her parents were unknown. They left her long ago. At the orphanage, the girl, like all the children there, was taught to read and write. While she was studying at the orphanage，she learned something else－to be independent.
At twenty-one，she left the orphanage and began work as a secretary. And then, in 1975, while she was still working as an ordinary secretary, something special happened. She entered the Miss Hong Kong competition and won it. This was the turning point in her life. Now her name, Mary Cheung, was known to everybody.
Mary entered the competition because she wanted to show that orphanage girls could be something. Winning the competition gave her the chance to start a new life. This led her first into television and then into business as a manager. When she was working as a manager, she had trouble with her reports. "My English just wasn't good enough." she says. Luckily, she had a boyfriend (who later became her husband) to help her.
Mary studied management at Hong Kong Polytechnic and graduated in 1980.
She started her own business in 1985. But she did not stop developing herself. She then studied at the University of Hong Kong. Since 1987，she had spent a lot of time on photography. She has held several
exhibitions of her work in many places－China, New Zealand and Paris.
She still found time, however, to work on TV, write for newspapers and bring up her family.
The girl from the street has come a long way, but her journey is not finished yet.
1、Before Mary Cheung was brought to the orphanage, she had lived in the
streets for many years.
The sentence "orphanage girls could be something" means that orphanage girls could be popular and successful.
Her life changed in 1985.
This passage is probably taken from a novel.
Mary's boyfriend was good at English.

第一次作业参考答案
第一次作业参考答案 1、、电能生产的主要特点有哪些？ 答：电能生产的主要特点可以归纳为以下三点。①电能生产的连续性特点；由于电能不能大量储存，电能的生产、输送和消费是同时完成的。②电能生产瞬时性的特点；这是因为电能的传输速度非常快（接近光速），电力系统中任何一点发生故障都马上影响到整个电力系统。③电能生产重要性的特点；电能清洁卫生、易于转换、便于实现自动控制，因此国民经济各部门绝大多数以电能作为能源，而电能又不能储存，所以电能供应的中断或减少将对国名经济产生重大影响。 2、对电力系统运行的基本要求是什么？ 答：对电力系统运行的基本要求有：①保证对用户的供电可靠性；②电能质量要好；③电力系统运行经济性要好；④对环境的不良影响要小。 3、电力系统中负荷的分类（I、II、III类负荷）是根据什么原则进行的？各类负荷对供电可靠性的要求是什么？ 答：电力系统中负荷的分类是根据用户的重要程度和供电中断或减少对用户所造成的危害的大小来划分的，凡供电中断将导致设备损坏、人员伤亡、产品报废、社会秩序还乱、政治影响大的用户的用电设备称为I类负荷；凡供电中断或减少将导致产品产量下降、人民生活受到影响的用户的用电设备称为II类负荷；I类、II类负荷以外的负荷称为III类负荷。 I类负荷对供电可靠性的要求是任何情况下不得中断供电； II类负荷对供电可靠性的要求是尽可能不中断供电； III类负荷可以停电。 4、标出下图所示电力系统中发电机、变压器的额定电压。（图中已标出线路的额定电压）
答：上述电力系统中发电机、变压器的额定电压如下： G ：10.5KV ；T1：10.5/242KV ；T2：220/121/38.5KV ；T3：35/6.3KV 5、为什么110KV 及以上的架空输电线路需要全线架设避雷线而35KV 及以下架空输电线路不需全线架设避雷线？ 答：因为110KV 及以上系统采用中性点直接接地的中性点运行方式，这种运行方式的优点是：正常运行情况下各相对地电压为相电压，系统发生单相接地短路故障时，非故障相对地电压仍为相电压，电气设备和输电线路的对地绝缘只要按承受相电压考虑，从而降低电气设备和输电线路的绝缘费用，提高电力系统运行的经济性；缺点是发生单相接地短路时需要切除故障线路，供电可靠性差。考虑到输电线路的单相接地绝大部分是由于雷击输电线路引起，全线路架设避雷线，就是为了减少雷击输电线路造成单相接地短路故障的机会，提高220KV 电力系统的供电可靠性。 35KV 及以下系统采用中性点不接地或经消弧线圈接地的中性点运行方式，即使雷击输电 线路造成单相接地时，电力系统也可以继续运行，供电可靠性高，所以无需全线架设避雷线。 6、在下图所示的电力系统中已知KV U 3/10=φ，A U C 3530=φω,如要把单相接地时流过接地点的电流补偿到20A ，请计算所需消弧线圈的电感系数。 解： 单相接地故障时的相量图如下：

大学英语4课文原文
Para1 An artist who seeks fame is like a dogchasing his own tail who, when he captures it, does not know what else to do but to continue chasing it.The cruelty of success is that it often leads those who seek such success to participate in their own destruction. 艺术家追求成名，如同狗自逐其尾，一旦追到手，除了继续追逐不知还能做些什么。成功之残酷正在于它常常让那些追逐成功者自寻毁灭。 "Don't quit your day job!" is advice frequently given by understandably pessimistic family members and friends to a budding artist who is trying hard to succeed. The conquest of fame is difficult at best, and many end up emotionally if not financially bankrupt. Still, impure motives such as the desire for worshipping fans and praise from peers may spur the artist on. The lure of drowning in fame's imperial glory is not easily resisted. 对一名正努力追求成功并刚刚崭露头角的艺术家，其亲朋常常会建议“正经的饭碗不能丢！”他们的担心不无道理。追求出人头地，最乐观地说也困难重重，许多人到最后即使不是穷困潦倒，也是几近精神崩溃。 Fame's spotlight can be hotter than a tropical jungle－a fraud is quickly exposed, and the pressure of so much attention is too much for most to endure.It takes you out of yourself: You must be what the public thinks you are, not what you really are or could be. The performer, like the politician, must often please his or her audiences by saying things he or she does not mean or fully believe. Curiously enough, it is those who fail that reap the greatest reward: freedom! They enjoy the freedom to express themselves in unique and original ways without fear of losing the support of fans. Failed artists may find comfort in knowing that many great artists never found fame until well after they had passed away or in knowing that they did not sell out. They may justify their failure by convincing themselves their genius is too sophisticated for contemporary audiences. Unit2 He was an immensely talented man, determined to a degree unusual even in the ranks of Hollywood stars. His huge fame gave him the freedom—and, more importantly, the money—to be his own master. He already had the urge to explore and extend a talent he discovered in himself as he went along. "It can't be me. Is that possible? How extraordinary," is how he greeted the first sight of himself as the Tramp on the screen. But that shock rousedhis imagination.Chaplin didn't have his jokes written into a script in advance; he was the kind of comic who used his physical senses to invent his art as he went along. Lifeless objects especially helped Chaplin make "contact" with himself as an artist. He turned them into other kinds of objects. Thus, a broken alarm clock in the movie The Pawnbroker became a "sick" patient undergoing surgery; boots were boiled in his film The Gold Rush and their soles eaten with salt and pepper like prime cuts of fish (the nails being removed like fish bones). This physical transformation, plus the skill with which he executed it again and again, is surely the secret of Chaplin's great comedy. He also had a deep need to be loved—and a corresponding fear of being betrayed. The two were hard to combine and sometimes—as in his early marriages—the collision between them resulted in disaster. Yet even this painfully-bought self-knowledge found its way into his comic creations. The Tramp never loses his faith in the flower girl who'll be waiting to walk into the sunset with him; while the other side of Chaplin makes Monsieur Verdoux, the French wife killer, into a symbol of hatred for women.

一、简答题 1、运营系统有哪些特征？ 服务业占GDP比重增大，制造业与服务业两者日益融合，运营管理系统逐渐从制造业扩展到服务业中。 质量定义扩展，如何从有形产品质量与服务质量两方面更加全面的满足客户的需求越来越成为当今管理者面临的主要挑战之一。 运营管理理念向其他职能领域扩展，广泛应用于运营职能部门的运营管理工具和理念同样也可以应用于其他职能部门，例如质量管理和过程分析。 2、社会组织的三项基本职能是什么？他们之间的关系如何？ 其基本职能是生产运作，理财，营销 联系：三项基本职能是相互依存的，三项基本职能连同组织的其他只能都是组织不可缺少的，且每项职能都依赖于其他职能。 3、分别对制造业与服务业中的大量大批生产与单件小批生产各举一例，并说明其特点。 制造业中的大批量生产：电脑组件生产。 制造业中的单件小批生产：大桥建设 服务业中的大批量生产：铁路运输 服务业中的单件小批生产：理发 大批量生产特点：大批量生产基于产品或零件的互换性，标准化和系列化的应用，刚性生产线大大提高了生产效率，降低了生产成本，其显著的特点是产品结构稳定、自动化程度高。但是缺点也相当明显，但是产品单一，缺乏多样性，生产线的初始投入大，建设周期长，柔性差，无法适应变化愈来愈快的市场需求和激烈的竞争。 单件小批生产特点：产品制造周期长，订货期长；通用化设备，用人多，生产效率低，劳动生产率低；成本高；产品质量不易保证。 4、制造业与服务业在产品特性、储存性、与顾客的接触性、响应顾客的时间、 5、组织的基本职能有哪些？相互间的关系如何？ 组织的职能主要有组织结构的设计、适度的分权与授权、组织内部人员的选择和配备、组织文化的培育和建设、组织运作和组织变革、组织与外部环境的关系等方面。 6、举例说明5个服务业及其特性 研究项目，博士生，保健，美容美发，快餐服务
第一次 作业答案
第二章财务管理的基础知识 一、计算题 1.某企业年初投资100万元生产一种新产品，预计每年年末可得净收益10万元，投资年限为10年，年利率为5%。【要求】 （1）计算该投资项目年收益的现值和终值。 （2）计算年初投资额的终值。 解：（1）年收益现值 P= 10×（P/A，5%，10） = 10×7.7217 = 77.217 (万元) 年收益终值 F= 10×（F/A，5%，10） =10×12.578 =125.78（万元） （2）年初投资额终值 F=100×（F/P，5%，10） =100×1.6289 =162.89（万元）
2.某人准备5年后支付一笔10 000元的款项，年利率为5%。【要求】计算此人现在应存入银行多少钱，5年的复利利息为多少元。 解：复利现值 P=10000×（P/F，5%，5） =10000×0.7835 =7835（元） 复利利息 I=F-P =10000-7835 =2165（元） 3.某企业2003年年初投资一个项目，预计从2006年起至2010年每年年末可获得净收益20万元，年利率为5%。 【要求】计算该投资项目年净收益的终值和现值。 解:年净收益的终值 F=20×（F/A，5%，5） =20×5.5256 =110.512（万元）
年收益的现值 P=20×[（P/A，i，m+n）﹣（P/A，i，m） =20×[（P/A，5%，8）﹣（P/A，5%，3） =20×（6.4632﹣2.7232） =74.796（万元） 4.某企业投资一个项目，每年年初投入10万元，连续投资3年，年利率为5%。 【要求】 （1）计算该项目3年后的投资总额 （2）若3年的投资额于年初一次性投入，投资总额是多少？ 解：（1）预付年金终值 F=10×（F/A，5%，3）×（1+5%） =10×3.1525×1.05 =33.10（万元） （2）预付年金现值 P=10×（P/A，5%，3）×（1+5%） =10×2.7232×1.05 =28.59（万元）
