2011金融复试笔试面试回忆版,不断补全中。
年纪大记忆差了,关于复试只记得零散的东西,希望这次参加复试的朋友多多补充,以助来者。
我为人人,人人为我。
一、笔试这次笔试和以前不一样,多了十个单项选择题,每个两分,比较简单,非常像证券从业资格考试的选择题。
第一个是计算固定增长率股票的内在价值,其他是什么,一个也想不起来了。
4个名解每个五分:多头排列,市净率,看涨期权,资产证券化4个简答:简述金融监管的三公原则的内容、开放型基金和封闭型基金的联系和区别、简述有效市场理论、移动平均线对投资分析的影响论述题30分:给了则4月6日央行上调利率0.25百分点的新闻作材料,问对证券市场的影响二、面试面我的是刘少波、谭政勋、程静三位专业老师和一位英语老师没有要自我介绍,估计是因为料到大家都背过。
问到的专业问题大致有:1.次债危机的成因(汉、英)2.利率和汇率如何相互影响(英)3.财务和公司金融的区别(英)4.资本资产定价模型以及公式(汉)5.看涨期权(汉)6.什么是利率、汇率(英)7.你对央行上调利率和准备金率政策的看法(汉)追问a.这种政策具体是怎么抑制通胀的?b.市场上资金减少了,那么减少的资金到哪里去了?c.什么是准备金率8.简述有效市场理论(汉)9.基础金融工具和衍生金融工具有何区别?(英)10.为什么衍生产品的交易量、份额越来越大?(英)后面4个都是我直接被问到的,前6个是听别的同学说的。
我因为是跨专业,问的还比较基础,本专业的估计还要难一点。
另外,面的时候老师会比较咄咄逼人对你的每句话不停追问,不要慌张,要冷静下来思考问题。
预祝大家成功!。

China launched its fourth unmanned spacecraft “Shenzhou Ⅳ” on December 30 at the Ji uquan Satellite Launch Centre in Gansu Province. It was the 27th consecutive and successful laun ch of China - made rockets since October 1996. This launch has made it more realistic for China t o send a person into space on its own following Russia and the USA. Qi Faren,leading designer of the spacecraft system, said all the functions designed for manned flights have withstood the test of three previous, successful launches and return landings of the “Shenzhou”spaceships. China launched the “Shenzhou Ⅰ”, “Shenzhou Ⅱ”and “Shenzhou Ⅲ”spacecrafts in 1999,2001 and 2002 respectively. “Shouzhou Ⅳ” was to make it a more comfort able place in which astronauts can live and work. All parts of the application system for manned fl ight are aboard the “Shenzhou Ⅳ”craft in all test flights. C hina’s manned flight programme began in 1992. A number of unmanned t est flights will be launched before Chinese astronauts are sent into space. Leading scientists in cha rge of China’s manned space programme said the successful launch of the “Shenzhou Ⅳ” laid a solid founda tion for the country’s future task of sending Chinese astronauts to outer space. Officials at the centre said that“ Shenzhou Ⅴ”, a manned spacecraft, is expected to be launched later this year.41.How long did it take the fourth unmanned spacecraft to fly in space and land successfully?A.5daysB.6days C,8days D,7days42.when did China begin to launch rockets in order to send manned spaceship into space according to the text?A in 1992B in 1996C in 1999D in 200243.The italicized word “consecutive”(in Paragraph2) means”_____”.A,difficult B continuous C frequent D common44.Why can China successfully send up “Shenzhou IV”?A.Because all the parts of the spacecraft work well.B.Because China has launched manned spacecraft very successfully.C.Because Chinese scientists made effort to launch three “Shenzhou”spacecrafts into and all the fu nctions have withstood the test of successful launches into space and return landing on earth.45.Which of the following may be the best title for the text?A.China`s Success in Launching “Shenzhou V”B.China`s Dream of Moon to Come True.C.China`s Spacecraft Flight ,”Shenzhou”D.China`s Manned Space Flight ProgrammePassage twoGreenspace fadilities are contributing to an important degree to the quality of city environment. Fo rtunately it is no longer necessary that every lecture or every book about this subject to start with t he proof of this idea. At present it is generally accepted ,although more as a self-evident statement than on the base of a closely-reasoned scientific proof.Recognizing the importance of greenspace i n the urban environment is a first step on the right way.This does not mean, however, that sufficien t details are known about the function of green space in towns and about the way in which the inha bitant are using these spaces.As to this subject I shall ,within the scope of this lecture ,enter into o ne aspect only ,namely the recreative function of green space facilities . The theoretical separation of living ,traffic and recreative which for many years , has been used in town-and-country plannin g ,has in my opinion resulted in disproportionate attention for forms of recreative far from home . However, there was relatively little attention for improvement possibilities in the direct neighborh ood of the home.We have come to the conclusion that is not right , because an important part of th e time which we do not pass in sleeping or working , is used for activities at and around home.So i t is obvious that recreative in the open air has to begin at the street-door of the house .The urban e nvironment has to offer as many recreation activities as possible ,and the design of these has to be such that more obligatory activities can also have a recreative aspect . The very best standard of li ving is nothing if it is possible to take a pleasant walk in the district , if the children cannot be allo wed to play in the streets , because the risks of traffic are too great , if during shopping you can no where find a spot for enjoying for a moment the nice weather ,in short ,if you only feel yourself athome after the street-door of your house is closed after you .46.The importance of the greenspace in the city environment _____.A.has been recognizedB.is paid little attention toC.is accepted on the basis of scientific proofD.is still unknown47.For many years town and country planning has _____.A.brought living area and places of environment close togetherB.put separated recreation possibilities in the neighborhoodC.improved recreational possibilities in the neighborhoodD.enabled people to reach the best standard of living48.The word ‘recreat ion” in the passage probably means_____A. activities done for pleasure or enjoymentB. doing something again in a creative wayC. dong something important after workD. required activities done after work49.According to the author ,greenspace should be designed_____A. to reduce the number of recreational activitiesB to attract more and more peopleC for people to do recreational activities at the street door or the houseD for people to conduct more activities in the neighborhood of the home50.The main idea of this passage is that_____A.attention must be paid to the improvement of recreationB,greenspace facilities is providing more recreational activitiesC,the city environment is providing more recreational acticitiesD,we should try our best to raise our living standardPassage ThreeThousands of years before Columbus came to the New World,theAmerican Indians entered North America by crossing a narrow stip of land that cnce connected Al asks and Siberia.The migrants entered a new world in which there were no people at all.But there were many animals to hunt,and there were forests there nuts,roots,and berries cold be gathered. When the Europeans came to the New World ,the Indians,at first ,taught the settlers how to plant c orn,bake fish,make canoes,and smoke tobacco .In return the whites intoroduced horses ,guns,gun-power ,alcohol.But at last ,there were struggles for land, and the struggles could have only one res ult-war.When the of land called reservations.Now,some of them irritated their tribal life,some wish to modernize the reservations.Indians have chosen-a future in modern technologv and education, or the reviva of ancient tradition and treaties.51.The lndians entered North America___A.with ColumbusB.before Columbus didC.after COlumbus'arrivalD.in 18 thcentury.52.The indians moved to a new world which was___A.once settled by EuropeansB.inhabited by primitive menC.inhabited in by American migrantspletely uninhabited by other people53.As soon as the Europeans set their foot on the New World,they___A.were hostile to the IndiansB.kept terms with IndiansC.didn't treat the Indians in a friendly wayD.traded with Indians friendly54.The most accurate statement about contemporavy Indians is___.A.most Indians reject modern culture and technologyB.some Indians preserve conventional life styleC.some Indians have adopted modern culture and technologyD.both B and C55.The Indians were good at___.A.struggles for landB.making boatsC.contemporary tribal lifeD.the revival their traditionPassage fourFor an increasing number of students at American universities, Old is suddenly in. The reason is o bvious: the graying of America means jobs, coupled with the aging of the baby-boom generation, a longer life span means that the nation’s elderly population is bound to expand significantly over t he next 50 years. By 2050, 25 percent of all Americans will be older than 65, up from 14 percent i n 1995. The change poses profound questions for government and society, of course. But it also cr eates career opportunities in medicine and health professions, and in law and business as well. “In addition to the doctors, we’re going to need more sociologists, biologists, urban planners and speci alized lawyers,” says Professor Edward Schneider of the University of Southern C alifornia’s (USC ) School of Gerontology Lawyers can specialize in “elder law,” which covers everything from tru sts and estates to nursing-home abuse and age discrimination. Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest gr oup of retirees in human history. “Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree will have a license to print money,” one professor says. Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found s he was “really bored with bacteria.” So she took a class in gerontology and discovered that she lied it. She says, “I did volunteer work in retirement homes and it was very satis fying.”56 “... Old is suddenly in” (Line 1, Para. 1) most probably means“________”.A) America has suddenly become a nation of old peopleB) gerontology has suddenly become popularC) more elderly professors are found on American campusesD) American colleges have realized the need of enrolling older students57. With the aging of America, lawyers can benefit ________.A) from the adoption of the “elder law”B) from rendering special services to the elderlyC) by enriching their professional knowledgeD) by winning the trust of the elderly to promote their own interests58. Why can businessmen make money in the emerging elder market?A) Retirees are more generous in spending money.B) They can employ more gerontologists.C) The elderly possess an enormous purchasing power.D) There are more elderly people working than before.59. Who can make big money in the new century according to the passage?A) Retirees who are business-minded.B) The volunteer workers in retirement homes. C) College graduates with an MBA or law degree.D) Professionals with a good knowledge of gerontology.60. It can be seen from the passage that the expansion of America’selderly population ________.A) will provide good job opportunities in many areasB) will impose an unbearable burden on societyC) may lead to nursing home abuse and age discriminationD) will create new fields of study in universities答案: I.1-10BDBCA DCDAA11-20 DBACA DBDCAⅡ.21-30 BACDA BDCCA 31-40 DABAC BADBC。

在甲出差的时候,丙找到房屋中介丁表示委托丁购房,丁与乙商量,乙同意以13万的价格出卖,然后丁告诉丙房屋的价格为15万元,并要乙不告诉丙真实情况,丙支付了五万元,乙把房屋钥匙交给了丙,但是说房屋产权证在甲的单位等甲回来再办理。
甲回来后得知房地产又涨价了要求丙再付两万元才能办产权登记,丙不同意,于是甲已17万元的价格将房屋卖给了戊并办理的房屋产权登记,戊要求丙搬离房屋,丙不同意,搞到法院说甲与戊的行为侵犯了他的所有权,要求法院撤销甲与戊之间的合同,而甲主张房屋是夫妻共同财产,乙处分没有得到他的同意而且中介丁存在欺诈,所以买卖合同是无效的。
请用民法有关原理,尤其是物权法的原理分析这个案例。

最后,考过的童鞋快来想想哇,判断题判断题,偶这脑袋快成浆糊了……回报论坛——2011北京华电电路理论试题[回忆版]本帖最后由diort 于2011-1-25 21:48 编辑我今年报考电工理论与新技术,之前也在论坛求09,10年真题无果。
北京校区管真题太严,总之这两年的真题同08年之前出题的思路非常不同。
我光荣战死沙场,趁热把题目回忆出来,以飨学弟学妹。
试卷分基本计算和综合计算。
基本计算共10小题,每题七分。
综合计算六道每题10分15分不等。
与08年前九道大综合不同。
一、(序号不分前后,记不得了)1、给定电路图其它各量和固定电阻值,求三个电阻的电流和电压。
(易,kvl,kcl,var)2、给定电路图,含电压源和电流源,加上电流源后电阻多消耗功率72w,求电流源Is。
3、给定电路图,两个独立回路中间用一条导线连接,问其中一回路中的2v电压源用多大电阻替代后其他元件功率不变。
4、均匀传输线,八分之波长,知Zc求输入阻抗Zin。
5、给定电路图含受控电流源,未给具体数字,含参数k,求Z参数。
6、含受控源的电路求Req(外加电源法)7、三个电感两两耦合,问当端口开路和短路时其中一个电感上的电压分别是多少,考查去耦。
8、谐波分析法求电流,易。
9、可变阻抗调到多大可获最大功率。
可变电阻并联一电阻,我化不出戴维南,大家自己找找类似题目吧。
10、知非线性电阻上电流和其外加电压的关系函数式,三次函数,求其他元件上的电流。
二、回路电流法求电压或电流。
三、运算法求某元件电压u。
(我化出复频域后居然上下都有s的三次方,没算出来,杯具了)四、三相电路星型负载和三角形负载并联,知阻值,有线路阻抗,知阻值,线电压380,AB两相间接功率表。
求1、Y阻抗和三角阻抗的线电流相电流及线电压相电压。
2、功率表读数。
3、画两表法测三角型阻抗的功率的电路图。
五、电压为正弦形式,求其他元件上的电压电流(时域法)六、独立电压源Us与线性无源网络并联,网络端口电压Ut。
网络零输入响应为U,加Us1时全响应为Ut1,问当Us2时,全响应Ut2为多少。
(具体数不记得,基本都是e的负几次方)七、不记得。
自我感觉及不了格,打开卷子一看题量很大其实就有些傻眼,做不完,做了不保证对,何况还有许多没做。
小题都不算小。
一定一定要扎实。
希望对来年考的人有帮助吧。
