自动化专业英语考试答案
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。

And even if he does not become very rich, he wants people to think that he is. That is what “keeping up with the Joneses” is about. It is the story of someone who tried to look as rich as his neighbors.The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $125 a week at the age of 23. That was a lot of money in those days. He got married and moved with his wife to a very wealthy neighborhood outside New York City. When he saw that rich people rode horses, Momand went horse-riding everyday. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.It was like a race, but one could never finish this race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They moved back to an apartment in New York City.Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it “Keeping up with the Joneses” because “Jones” is a very common name in the Untie States. “Keep up with the Joneses” came to mean keeping up with the rich lifestyle of the people around you. Momand’s series appeared in different newspapers across the country for over 28 years.People never seem to get tried of keeping up with the Joneses. And there are “Joneses” in every city of the world. Butone must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.31. Some people want to keep up with the Joneses because they _____.A. want to be as rich as their neighborsB. want others to know or to think that they are richC. don’t want others to know they are richD. want to be happy32. It can be inferred from the story that rich people like to _____.A. live outside New York CityB. live in New York CityC. live in apartmentsD. have many neighbors33. The underlined word “ neighborhood” in Para.2 means ________.A. a person who lives near anotherB. people living in an areaC. an area near the place referred toD. an area in another town or city34. Arthur Momand used the name “Jones” in his series of short stories because “Jones” is __________.A. an important nameB. a popular name in the United StatesC. his neighbor’s nameD. not a good name35. According to the writer, it is _____ to keep up with the Joneses.A. correctB. interestingC. impossibleD. goodPassage TwoPaper is one of the most important products ever invented by man. Wide spread use of written language would not have been possible without some cheap and practical material to write on. The invention of paper meant that more people could be educated because more books could be printed and distributed. Together with the printing press, paper provided an extremely important way to communicate knowledge.How much paper do you use every year? Probably you cannot answer that question quickly. In 1990 the world’s use of paper was about one kilogram for each person a year. Now some countries use as much as 50 kilograms of paper for each person a year. Countries like the United States, England and Sweden use more paper than other countries.Paper, like many other things that we use today, was first made in China. In Egypt and the West, paper was not very commonly used before the year 1400. The Egyptians wrote on a kind of material made of a water plant. Europeans used parchment for many hundreds of year. Parchment was very strong; it was made from the skin of certain young animals. We have learnt of the most important facts of European history from records that were kept on parchment. (208words)36.What’s the meaning for the word “parchment”?A.The skin of young animalsB.A kind of paper made from the skin of certain young animalsC.The paper used by European countriesD.The paper of Egypt37. Which of the following is not mentioned about the invention of paper?A.More jobs could be provided than beforeB.More people could be educated than beforeC.More books could be printed and distributedD.More ways could be used to exchange knowledge38.When did the Egyptians begin to use paper widely?A.Around 1400B.Around 1900C.Around 400D.Around 90039. Which of the following countries uses more paper for each person a year?A.ChinaB.SwedenC.EgyptD.Japan40.What is the main idea of this short talk?A.More and more paper is being consumed nowadaysB.Paper enables people to receive education more easilyC.The invention of paper is of great significance to manD.Paper contributes a lot to the keeping of historical recordsPassage ThreeThere are three kinds of goals: short-term,medium-range and long-term goals.Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed.The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief in your ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase.Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing.We should never allow a long-term goal to limit us or our course of action.41.Our long-term goals mean a lot__.A. if we complete our short-range goalsB . if we cannot reach solid short-term goalsC .if we write down the datesD .if we put forward some plans42.New short-term goals are bulid upon__.A.two yearsB .long-term goalsC .current activitiesD .the goals that have been completed43.When we complete each step of our goals ,__.A.we will win final successB .we are overwhelmedC .we should build up confidence of successD .we should strong desire for setting new goals44.Once our goals are drawn up,__.A.we should stick to them until we complete themB.we may change our goals as we have new ideas and opportunitiesC .we had better wait for the exciting news of successD .we have made great decision45.It is implied but not stated in the passage that ___.A.those who habe long-term goals will succeedB .writing down the dates may discourage youC .the goal is only a guide for us to reach our desinationD .every should have a goalPassage FourThe economy of the United states after 1952 was the econnomy of a well-fed,almost fully employed people.Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, a typical ye ar of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery.National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to the oppsite-depression.46. What is the best title of the passage?A. The Agriculatural Trends of 1950’sB . The Unemployment Rate of 1950’sC . U.S. Economy in the 50’sD . The Federal Budget of 195247. In Line 4 , the word “boom” could best be replaced by______.A. nearby explosionB . thunderous noiseC . general public supportD . rapid economic growth48. It can be inferred the national from the passage that most people in the United States in 1955 viewed thenational economy with an air of _________.A. confidenceB . confusionC . disappointmentD . suspicion49. Which of the following were LEAST satisfied with the national economy in the 1950’s?A. EconomistsB . FrmaersC . PoliticiansD . Steelworkers50. The passage states that incom available for spending in the U.S. was greater in 1955 than in 1950 . How muchwas it ?A. 60%B . 50%C . 33%D . 90%Part IV Translation (每题2分，共20分)Section A (每题2分，共10分)Directions: Translate the following sentences into Chinese.

The ease and speed with which bus in ess tran sacti ons can be carried out over the web has bee n a key force in rapid growth of electrical commerce.2、用户互动，包括在线客户服务和在线调查，提供了新的交流渠道，这在以前是不可能也是非常低效的。
Customers in teractio ns in cludi ng online customer services and online survey,provides a new channel of com muni catio ns,which were not previously available and very in efficient.3、并绕式直流电动机的调速性能很好。
当负载增加时，由于电枢上电压降的增加，其转速会稍微降低。
The DC shunt-wound motor has a good speed regulati on. The speed will decrease slightly when the load in crease due to the in crease in the voltage drop across the armature.4、用户用于在建筑内传输电能的配电系统类型取决于各自的安装要求，居民住宅通常使用最简单的类型。
The type of distribution system that the con sumer uses to tran smit power with in build ing depe nds on the requireme nts of particular in stallati on, reside ntial buildi ngs gen erally use the simplest one.5、控制系统中控制器参数固定时，其性能将在一定程度上总是取决于被控设备或系统的参数。
The performa nee of a con trol system hav ing a con troller with fixed parameters will always depend to some extent on parameters of the equipme nt or system being con trolled.6、新设备替代老设备将会使产量大大增加。
The substituti on of new equipme nt to the old result in in crease in producti on.7、无论何时，若某元件上电流参考方向与电压参考方向相同时，在任何涉及电压和电流的公式中取正号。
When ever, the reference directi on for the circuit in an element is the directi on of the reference voltage drop across the eleme nt use a positi on sig n in any impression relates to the voltage to the curre nt.8运算放大器最初是作为模拟计算机的一个基本构成算元出现的，由于它被用数学运算，所以被称为运算放大器。
The operati onal amplifier circuit existed initially came into existence firstly as a basic building block of analog computers. It was referred as operational because it was used to compleme nt mathematical operati ons.9、电感是在一个磁性或非磁性材料的磁芯上绕制一卷线圈构成。
An in ductor is composed of a coil of wires woun ded around a core whose material maybe magn etic or nonmagn etic.10、变压器由两个线圈恰当安放而成的，一个线圈所产生的变化磁通将连接至另一个线圈。
A transformer is constructed of two coils placed so that charging flux developed by one will li nk the other. 三、英译汉（5-6个，共30分，1 个课外）1、Electrical personnel use many differe nt types of measuri ng instruments.Some jobs require very accurate measurements while other jobs n eed only rough estimates. Some in strume nts are used solely to determine whether or not a circuit is complete.电子技术人员使用许多不同类型的测量仪器。
一些工作需要精确的测量而另一些工作只需粗略估计。
有些仪器仅仅被用来确定确定电路是否完整。
2、The importance of never allowing the actual value to exceed the maximum value indicated on the meter can not be overemphasized. 不允许被测的实际数值超过仪表最大允许值的要求再强调也不过分。
3、Since the heat sinks for both stud-m oun ted and hockey puck devices can also carry the electric current，they must be electrically isolated from their mecha ni cal moun ti ngs.由于栓接式和冰球式器件的散热器都能传递电流，它们必须与机械托电气绝缘。
4、I f the entire system is good, every acoustic variation of the air will be recorded on the disk and,when the record is played back through a similar system and the sig nal reradiated as sound energy by a loudspeaker,the result ing sound should faithfully reproduce the origi nal music.如果整个系统正常，每一次声波振动都会记录在圆盘上，并且当该记录通过类似的系统重放，信号以声能的形式从扬声器辐射出来，所产生的声音能如实地重现原始音乐。
5、I n formatio n can be com muni cate in digital from if the message is capable of being defined by a series of yes/no stateme nts.Thereca n be only two states of each variable used in conveying the in formatio n.如果信息能被一系列的YES/NO所定义，信息就能以数字形式确定。
每个变量只可能有两种状态在传送信息方面使用。
6、M ost early discoveries related to electrical machinery operation dealt with direct-curre nt systems.Alternati ng-curre nt(AC)powe r gen eratio n and distributi on became widespread a short time later.大多数早期的发明都与处理直流电系统的电机操作有关。
