flow as the movement of positive charges, that is, opposite to the flow of negative charges, as Fig.l-1 illustrates. This convention was introduced by Benjamin Franklin (l706 ~ l790), the American scientist and inventor. Although we now know that current in metallic conductors is due to negatively charged electrons, we will follow the universally accepted convention that current is the net flow of positive charges. Thus, Electric current is the time rate of charge, measured in amperes (A). Mathematically, the relationship among current i, charge q, and time t is

For each question there are four choices marked A, B,C and D. Chose the best answer to each question.Passage OneEverybody knows that the favorite food in the United States is the hamburger. It seems impossible,but people eat 34,000,000,000 hamburgers a year. This is enough to make a line of hamburgers around the world four times.The favorite place to buy a hamburger is a fast-food restaurant. In these restaurants,people order their food,wait just a few minutes and carry it to their tables themselves. They can eat it in the restaurant or take the food out and eat it at home,at work,or in a park. At some restaurants people can drive up beside a window. They order the food,and a worker hands it to them through the window. Then they eat in their car.Hamburgers are not the only kind of food that fast-food restaurants serve. Some serve fish,chicken,beef,sandwiches,or Mexican food. They also serve fries (French fried potatoes),shakes (a drink made from milk and ice cream),soft drinks,and coffee. Fast-food restaurants are very popular because the service is fast and the food is inexpensive.For many people,this is more important than the quality of the food. These restaurants are also popular because the food is always the same. People know that if they eat at a company's restaurant in the north or south of the city,the food will be the same,if they eat in New York or San Francisco,it will still be the same.11. According to the passage,what food do Americans like best?A. Beef.B. Sandwiches.C. Hamburger.D. Fries.12. Where can Americans eat a hamburger?A. At home.B. In a park.A-9-3C. In their car.D. At any of the places mentioned above.13.Fast food is .A.deliciousB. unpopularC. inexpensiveD. of high quality14. The last paragraph tells us________.A. fast-food is very popularB. people like to eat in fast-food restaurantsC. why fast-food restaurants are very popularD. you can eat fast-food any where in the US15. What is the main idea of the passage?A. Fast-food restaurants are very popular.B. People in the US eat enough hamburgers to make a line around the world.C. Some people eat fast food in parks.D. People can eat fast food at work or in a park.Passage TwoGoing to court can be frightening,especially if you are a child. You may have to stand up in the witness box,and swear to tell the truth and answer questions in front of a crowd of adults. It would be even more frightening if you were the victim of a crime and you had to sit in the same courtroom as the person accused of attacking you,for instance. So the law in Britain has made it easier for children to act as witnesses. Children are allowed to tell what they know,from another room in the same courthouse,in this way they do not have to face all those people in the courtroom.It works on a closed-circuit (闭路的)television link,which means that the TV only operates inside the court. The child witness sits in a room with a social worker in front of a TV camera. Everyone in the court room can see the child on a TV screen,but the child can only see the judge and the lawyers who will ask him or her questions. The system has been so successful that it will be extended to more courts this year.Another way to make it easy for a child to act a witness is to set up a screen in the court room around the witness box so that the child cannot see the defendant (被告). Information given by children can be very important to a court trial,butbefore1988 theA-9-4law did not really recognize that children told the truth. It stated that anything a child said in court had to be supported by other evidence in the case.16. A child witness,if he were the victim of the crime,would be frightened most by________. A. all the questions he had to answerB. the crowd of adults he had to faceC. the judge and the lawyersD. the person accused of attacking him17. The most important point of the new system that made things easier for a child witne ss is that____.A. he does not see the defendantB. he speaks in front of a TV cameraC. he is in another room in the same courthouseD. everyone in the courtroom can see the child18.What does the author think of the new system according to the third paragraph?A. Not very good.B. Very successful.C. Just an experiment.D. Hardly acceptable.19, Has the law always recognized the importance of children's information in court?A. No.B. Yes.C. Not until 1988.D. Before 1988,yes.20. The word “case” in the last paragraph means________.A. a particular situationB. a particular incidentC. a trialD. a boxPassage ThreeAlbeit Einstein had a great effect on science and history,greater than only a few other men have achieved. An American university president once commented that Einstein had created a new outlook,a new view of the universe. It may be some time before the average mind understands fully the identity of time and space and so on —butA-9-5even ordinary man understands now that the universe is something larger than ever thought before.By 1914 the young Einstein had gained world fame. He accepted the offer to become a professor at the Prussian Academy of Science in Berlin. He had few duties,little teaching and unlimited opportunities for study,but soon his peace and quiet were broken by the First World War.Einstein hated violence. The misery of war affected him deeply,and he sat unhappily in his office doing little. He lost interest in his research. Only when peace came in 1918 was he able to get back to work.In the years following World War I honors were increasingly given to him. He became the head of the Kaiser Whihem Institute on Theoretical Physics. In 1921 he won the Nobel Prize,and he was honored in Germany until the rise of Nazism when he was driven from Germany because he was a Jew.21. According to the American university president,________.A. everyone understands Einstein's theory todayB. Einstein achieved more than any other scientists in historyC. the theory of relativity can be quickly learned by everyoneD. our ideas about the universe are different today because of Einstein22. According to paragraph two,Albert Einstein________.A. was a famous chemistB. became a professional researcherC. was popularA.D. enjoyed reading about war23. What did Albert Einstein do in the First World War?A. He joined the army.B. He participated in anti-war activities.C. He was unhappy and did little.D. He went to America.24.After World War I,Albert Einstein________.A. was forced to leave the Kaiser Whihem Institute on Theoretical PhysicsB. was acknowledged by scientific community because of his devotionC. was forced to work for the NazisD. was appointed the head of the Kaiser Whihem Institute on Theoretical Physics by the Nazis25. It may be concluded that________.A. Albert Einstein had no other interests than scienceB. Einstein was forced to serve in the German armyA-9-6C. Germans usually have a high respect for scienceD. his reputation was ruined because of his work during World War IPart Ⅲ Vocabulary and Structure (20 points)Directions: In this section there are 30 incomplete sentences. For each sentence ther e are four choices marked A,B,C and D.

单词:20分,10个二。
句子翻译: 40分,8题1: P2A common method of analyzing an electrical network is mesh or loop analysis. The fundamentallaw that is applied in this method is Kirchhoff's first law, which states that the algebraic sun of thevoltages around a closed loop is 0 ,or , in any closed loop , the sum of the voltage rises must equal the sum of the voltage drops. Mesh analysis consists of assuming that currents~termed loopcurrents~flow in each loop of a network ,algebraically summing the vo ltage drops around eachloop ,and setting each sum equal to 0.分析电网络的一般方法是网孔分析法或回路分析法。
应用于此方法的基本定律是基尔霍夫第一定律,基尔霍夫第一定律指出:一个闭合回路中的电压代数和为0,换句话说,任一闭合回路中的电压升等于电压降。
网孔分析指的是:假设有一个电流——即所谓的回路电流——流过电路中的每一个回路,求每一个回路电压降的代数和,并令其为零。
2: P17Alternatively, suppose that there had been attached to each pilot’s seat an electronic device that provided an output voltage which is V 1 when the seat is occupied and V2 when the seat is not occupied. Let us attach the designation “true”to the voltage level V2 so that the level V1 is “false”.Let us further construct an electr ic circuit with two sets of input terminals and one set of output terminals. The circuit is to have the property that the output vol tage will be V2 if and only if both inputs, i.e., one input AND s imultaneously the other, are at the level V2. Otherwise the output i s V1Finally let us connect the inputs to the devices on the chairs of pilots A and B and arrange that an alarm bell, connected to the ou tput Z, respond when the output is V2 (“true”)and not otherwise. We have then constructed a circuit which performs the AND operation and is capable of making the logical deduction that the plane is unpiloted when, indeed, both pilots leave the cockpit换句话说,假设每一位飞行员座位下面有一个电子装置,当座位上有人时,其输出电压为V1,当座位上无人时,其输出电压为V2。

翻译P.1The voltage across a pure inductor is defined by Faraday’law,which states that the voltage across the inductor is proportional to the rate of change with time of the current through the inductor.thus we have U=Ldi/dt.纯电感电压由法拉第定律定义,法拉第定律指出:电感两头的电压正比于流过电感的电流随时间的变化率。
所以可获取:U=Ldi/dt式中di/dt = 电流变化率,安培/秒;L =感觉系数,享利。
P.3A three-phase electric circuit is energized by three alternating emfs of the same frequency and differing in time phase by 120 electrical degrees .三相电压的产生三相电路可由三个频次同样在时间相位上相差120°电角度的电动势供电。
P.9One problem with electronic devices corresponding to the generalized amplifiers is that the gains,AU or AI ,depend upon internal properties of two-port system( ).This makes design difficult since these parameters usually vary from device to device ,as well as temperature .运算放大器像广义放大器这样的电子器件存在的一个问题就是它们的增益 AU 或 AI 取决于双端口系统 (m、b、RI、Ro 等)的内部特征。
