主观题
一、简答题
1.域用户帐户和本地用户帐户之间的区别是什么?
答:域用户帐户和本地用户帐户之间的区别是:域用户帐户建立在域控制器的AD数据库内,用户可以利用域用户帐户登录域,并利用它来访问网络上的资源。当用户帐户建立在某台域控制器内后,该帐户会自动复制到同一域内的其他所有域控制器中;本地用户帐户建立在Windows 2000独立服务器,Windows 2000成员服务器或Windows 2000 Professional的本地安全数据库内,而不是域控制器内,用户可以利用本地用户帐户来登录此计算机,但是只能访问这台计算机内的资源,无法访问网络上的资源
2.网络协议的基本要素是什么?并说明其含义。
答:基本要素:语义、语法、规则
a)语义(semantics)。涉及用于协调与差错处理的控制信息。b)语法(syntax)。涉及数据及控制信息的格式、编码及信号电平等。定时(timing):涉及速度匹配和排序等
3.域名系统是如何解释域名的?
答:从概念上讲,域名解析自上而下进行,从根服务器开始直到树叶上的服务器。域名解析有两种方式:
1)反复解析(iterative solution):每一次联系一个不同的服务器。递归解析(recursive solution):请求一个名字服务器系统完成全部解析。2)递归解析(recursive solution):请求一个名字服务器系统完成全部解析
二、综合题
1.何谓链路的虚联接、虚通路和虚通道?ATM虚联接是如何建立的?
答:ATM采用面向联接的传输方式,将数据分割成固定长度的信元,通过虚联接进行交换。
ATM中的虚联接由虚通路(VP:Virtual Path)和虚通道(VC:Virtual Channel)组成,分别用VPI和VCI来标识。多个虚通道可以复用一个虚通路,而多个虚通路又可以复用一条传输链路、在一个传输链路上,每个虚联接可以用VPI和VCI的值惟一标识。
当发送端希望与接收端建立虚联接时,它首先通过UNI向ATM网络发送一个建立联接的请求。接收端接到该请求并同意建立联接后,一条虚联接才会被建立。虚联接用VPI/VCI来标识。
在虚联接中,相邻两个交换机间信元的VPI/VCI值保持不变,当信元经过交换机时,其信元头中VPI/VCI值将根据要发送的目的地,参照联接映像表被映射成新VPI/VCI.这样,通过一系列VP、VC交换,信元被准确地传送到目的地。
2.找出不能分配给主机的IP地址,并说明原因。A.131.107.256.80 B.231.222.0.11 C.126.1.0.0
D.198.121.254.255 E.202.117.34.32 答:A.第三个数256是非法值,每个数字都不能大于255 B.第一个数231是保留给组播的地址,不能用于主机地址 C.以全0结尾的IP地址是网络地址,不能用于主机地址 D.以全1结尾的IP地址是广播地址,不能用于主机地址
西安交通大学网络教育学院
3.某公司需要将5200台计算机从120个地点(假定每个地点的计算机数量大致上是平均的)连接到网络中。为此需要申请一个合法的IP地址。请回答以下问题:
1)该公司需要申请哪一类地址才能满足要求; 2)这个地址如何划分为子网,分配给120个物理网络;
3)这个网络中总共可以为多少台计算机单独分配地址;
4)给出地址的子网和主机部分的地址范围。
答:1)b类地址空间是216]5200,能够满足要求。故申请一个b类地址。
2)120最接近128=27,所以至少从主机位中借7位来划分子网。
3)每个子网的主机位为9位,故每个子网的主机数最多可以达到29-2=510,由于支持128个或126个子网(取决于路由协议),所以最大主机容量是128×510或126×510。4)第一个子网:a.b.0.0~ a.b.1.255 第二个子网:a.b.2.0~ a.b.3.255以此类推,共128个子网。

三、阅读理解、完形填空题(共5道小题)42.Once upon a time there lived a beautiful young woman and a handsome young man.They were very poor, but as they were deeply in love, they wanted to get married.The young people’s parents shook their heads.“You can’t get married yet”, they said.“Wait till you get a good job with good prospects.” So the young people waited until they found good jobs with good prospects and they were able to get married.They were still poor, of course.They didn’t have a house to live in or any furniture, but that didn’t matter.The young man had a good job with good prospects, so large organizations lent him the money he needed to buy a house, some furniture, all the latest electrical appliances and a car.The couple lived happily ever after paying off debts for the rest of their lives.And so ends another modern romantic fable.We live in a materialistic society and are trained from our earliest years to be acquisitive.Our possessions, “mine” and “yours”, are clearly labeled from early childhood.When we grow old enough to earn a living, it does not surprise us to discover that success is measured in terms of the money you earn.We spend the whole of our lives keeping up with our neighbors, the Joneses.If we buy a new television set, Jones is bound to buy a bigger and better one.If we buy a new car, we can be sure that Jones will go one better and get two new cars: one for his wife and one for himself.The most amusing thing about this game is that the Joneses and all the neighbors who are struggling frantically to keep up with them, are spending borrowed money kindly provided, at a suitable rate of interest, of course, by friendly banks, insurance companies, etc.[共5题](1)By the fable, the author wants to convey __________.(A)the value of love(B)importance of parents in marriage(C)good job is the basis of a happy marriage(D)we live in a materialistic society 你选择的答案: 前次作业时已经做对 [正确] 正确答案:D(2)In the second paragraph the phrase “keep up with the Joneses” means __________.(A)doing something in order to be as good as other people, because they are the best(B)doing something in order to show they have as much money as other people, rather than because they really want to do it(C)doing something with the Joneses in order to keep them company(D)doing something with the Joneses in order to learn their good points 你选择的答案: 前次作业时已经做对 [正确] 正确答案:B(3)According to the passage, which of the following statements is TRUE?(A)We don’t develop the concept of “possession” until the adulthood.(B)Joneses buy a new TV because the old one is too small.(C)Bigger TV and better cars are bought just to keep up with the Joneses.(D)Friendly banks lend Joneses the money at a very low rate of interest.你选择的答案: 前次作业时已经做对 [正确] 正确答案:C(4)Which one of the following best expresses the main idea of the passage?(A)Joneses and neighbors are spending borrowed money.(B)We live in a materialistic society and are trained from our earliest years to be acquisitive.(C)Our possessions, ‘mine’ and ‘yours’, are clearly labeled from early childhood.(D)We spend the whole of our lives keeping up with our neighbors, the Joneses.你选择的答案: 前次作业时已经做对 [正确] 正确答案:B(5)Which of the following best describes the author’s tone in this passage?(A)Ironic(B)Optimistic(C)Objective(D)Neutral 你选择的答案: 前次作业时已经做对 [正确] 正确答案:A 参考答案:
[第四单元];第5小题:A 从整篇文章作者使用的语句,如“„ so ends another modern romantic fable;get two new cars: one for his wife and one for himself;borrowed money kindly provided, at a suitable rate of interest, of course, by friendly banks, insurance companies”可以推断出作者的语气是讽刺的。所以选A。
43.In all American history, there is no story stranger than that of John A.Sutter.When the independence of California was declared in 1846, San Francisco was a small town of some 800 inhabitants.Then, in 1848, gold was discovered on land not far away.This land was owned by John A.Sutter.During the famous Gold Rush of 1849, there was a vast movement of people toward San Francisco and the gold fields.The city grew to three times its size in just a few weeks.Previously a quiet, pleasant town, San Francisco was changed almost overnight into a rough and crowded city.The same factors that operated to change San Francisco also changed the life of Sutter.Sutter was a citizen of Switzerland.He had come, penniless, in the spirit of adventure to the United States.By chance, he obtained the rights to a large piece of land, some seventy miles north of San Francisco.Here Sutter established his own private colony.As an intelligent, well-educated man, he built a fort, inside which he established a large trading post.He became a very rich man.Then in 1848, in a stream leading from a mill, one of Sutter’s workmen found some pieces of gold.At first, Sutter tried to keep the news quiet.He had dreams of becoming richer, perhaps the richest man in the whole world.But, within a few weeks, the news about the gold leaked out.Men descended upon his land from all directions.These people killed his cattle, stole his farm produce and tools, and tore down his buildings to obtain wood to build homes for themselves.The city of Sacramento sprang up where Sutter’s fort stood.On the site of his saw mill grew up the present city of Coloma.[共5题](1)Which of the following is TRUE about Sutter?(A)Poor as he was, Sutter was full of adventurous spirit.(B)Sutter got his college education in Switzerland.(C)Sutter was a colonist.(D)Sutter was the richest man in the whole world.你选择的答案: 前次作业时已经做对 [正确] 正确答案:A(2)From the passage we know that __________.(A)Sutter declared the news of gold discovery(B)men descended upon Sutter’s land to explore the gold for him(C)while building a saw mill, Sutter himself found some pieces of gold(D)the city of Sacramento sprang up because of the gold discovery 你选择的答案: 前次作业时已经做对 [正确] 正确答案:D

44.The automobile has many advantages.Above all, it offers people freedom to go wherever and whenever they want to go.The basic purpose of a motor vehicle is to get from point A to point B as cheaply, quickly, and safely as possible.However, to most people, cars are also personal fantasy machines that serve as symbols of power, success, speed, excitement, and adventure.In addition, much of the world’s economy is built on producing motor vehicles and supplying roads, services, and repairs for those vehicles.Half of the world’s paychecks are auto related.In the United States, one of every six dollars spent and one of every six non-farm jobs are connected to the automobile or related industries, such as oil, steel, rubber, plastics, automobile services, and highway construction.In spite of their advantages, motor vehicles have many harmful effects on human lives and on air, water, land, and wildlife resources.The automobile may be the most destructive machine ever invented.Though we tend to deny it, riding in cars is one of the most dangerous things we do in our daily lives.Since 1885, when Karl Benz built the first automobile, almost 18 million people have been killed by motor vehicles.Every year, cars and trucks worldwide kill an
average of 250,000 people-as many as were killed in the atomic bomb attacks on Hiroshima and Nagasaki-and injure or permanently disable ten million more.Half of the world’s people will be involved in an auto accident at some time during their lives.Since the automobile was introduced, almost three million Americans have been killed on the highways-about twice the number of Americans killed on the battlefield in all U.S.wars.In addition to the tragic loss of life, these accidents cost American society about $60 billion annually in lost income and in insurance, administrative, and legal expenses.Streets that used to be for people are now for cars.Pedestrians and people riding bicycles in the streets are subjected to noise, pollution, stress, and danger.Motor vehicles are the largest source of air pollution, producing a haze of smog over the world’s cities.In the United States, they produce at least 50% of the country’s air pollution.[共5题](1)Besides its basic purpose, Car also serves as a symbol of people’s _________.(A)occupation(B)status(C)character(D)reputation 你选择的答案: 前次作业时已经做对 [正确] 正确答案:B(2)According to the passage, the average number of people killed annually in traffic accidents around the world is __________.(A)60 million(B)250,000(C)3 million(D)18 million 你选择的答案: 前次作业时已经做对 [正确] 正确答案:B(3)A serious environmental problem resulting from automobiles is _________.(A)tragic loss of life(B)traffic jams(C)air pollution(D)mental stress 你选择的答案: 前次作业时已经做对 [正确] 正确答案:C(4)Which of the follow can be inferred from this passage?(A)Automobiles are an important part of the world’s economy.(B)Automobiles are becoming less dangerous.(C)Automobiles will produce less air pollution in the future.(D)Automobiles are killing more people in recent years than in the past.你选择的答案: 前次作业时已经做对 [正确] 正确答案:A(5)The title that suits the passage best is _________.(A)Automobile and Economy(B)Automobile and the Environment(C)The Problems with the Automobile(D)Advantages and Disadvantages of the Automobile 你选择的答案: 前次作业时已经做对 [正确] 正确答案:D 参考答案:
[第四单元];第5小题:D 主旨题。作者以“The automobile has many advantages”开篇,并从运输功能、经济作用等方面说明;然后以“In spite of their advantages, „”引出了汽车带来的负面影响。所以最好的标题是选项D,“汽车的好处和坏处”。
45.I don’t know how I became a writer, but I think it was because of a certain force in me that had to write and that finally burst through and found a channel.My people were of the working class of people.My father, a stone-cutter, was a man with a great respect and veneration for literature.He had a tremendous memory, and he loved poetry, and the poetry that he loved best was naturally of the rhetorical kind that such a man would like.Nevertheless it was good poetry, Hamlet’s Soliloquy, Macbeth, Mark Antony’s “Funeral Oration”, Grey’s “Elegy”, and all the rest of it.I heard it all as a child;I memorized and learned it all.He sent me to college to the state university.The desire to write, which had been strong during all my days in high school, grew stronger still.I was editor of the college paper, the college magazine, etc., and in my last year or two I was a member of a course in playwriting which had just been established there.I wrote several little one-act plays, still thinking I would become a lawyer or a newspaper man, never daring to believe I could seriously become a writer.Then I went to Harvard, wrote some more plays there, became obsessed with the idea that I had to be a playwright, left Harvard, had my plays rejected, and finally in the autumn of 1926, how, why, or in what manner I have never exactly been able to determine.But probably because the force in me that had to write at length sought out its channel, I began to write my first book in London, I was living all alone at that time.I had two rooms-a bedroom and a sitting room-in a litter square in Chelsea in which all the houses had that familiar, smoked brick and cream-yellow-plaster look.[共5题](1)We may conclude, in regard to the author’s development as a writer, that his father _________.(A)made an important contribution
(B)provided him with good education(C)opposed his becoming a writer(D)insisted that he memorize good poetry in order to learn how to be a writer 你选择的答案: 前次作业时已经做对 [正确] 正确答案:A(2)The author believes that he became a writer mostly because of _________.(A)his special talent(B)his father’s teaching(C)his study at Harvard(D)a strong hidden wish within him 你选择的答案: 前次作业时已经做对 [正确] 正确答案:D(3)Which of the following is TRUE about the author?(A)He began to think of becoming a writer at Harvard.(B)He had always been successful in his writing career.(C)He went to Harvard to learn to write plays.(D)He worked as a newspaper man before becoming a writer.你选择的答案: 前次作业时已经做对 [正确] 正确答案:D(4)The author really started on his way to become a writer _________.(A)when he was in high school(B)when he was studying at Harvard(C)when he lived in London(D)after he entered college 你选择的答案: 前次作业时已经做对 [正确] 正确答案:C(5)According to the passage, about the author’s life in 1926 which of the following conclusions CANNOT be safely drawn?(A)He lost the ability to determine in which direction he should go.(B)He was depressed about having his plays rejected.(C)He lived in a house which had smoked brick and cream-yellow-plaster look.(D)He started his first novel.你选择的答案: 前次作业时已经做对 [正确] 正确答案:A 参考答案:
[第四单元];第5小题:A 推断题。从文章最后一段“„left Harvard, had my plays rejected„”可以推断作者对于自己的剧作被拒感到沮丧;从“„in which all the houses had that familiar, smoked brick and cream-yellow-plaster look”可以推断他所居住的房子也是这样的;从“„in the autumn of 1926”以及“I began to write my first book„”
可以推知在1926年作者开始写第一本书。而选项A在文章中是没有根据的。所以选A,“他失去了决定前进方向的能力。”

month of November is in autumn, the main season for harvesting crops.The writer O.Henry called Thanksgiving the one holiday that is purely American.It is not a religious holiday.But it has spiritual meaning.Thanksgiving began with the first European settlers in America.They gathered their crops, celebrated and gave thanks for the food.Tradition says Pilgrim settlers from England celebrated the first Thanksgiving in 1621.There is evidence that settlers in other parts of America held earlier Thanksgiving celebrations.But the Pilgrims’ Thanksgiving story is the most popular.The Pilgrims were religious dissidents who fled oppression in England.They went first to the Netherlands.Then they left that country to establish a colony in North America.The Pilgrims landed in 1620 in what later became known as Plymouth, Massachusetts.Their voyage across the Atlantic Ocean was difficult.Their first months in America were difficult, too.About one hundred Pilgrims landed just as autumn was turning to winter.During the cold months that followed, about half of them died.When spring came, the Pilgrims began to plant crops.An American Indian named Squanto helped them.When summer ended, the Pilgrims had a good harvest of corn and barley.There was enough food to last through the winter.The Pilgrims decided to hold a celebration to give thanks for their harvest.Writings from that time say Pilgrim leader William Bradford set a date late in the year.He invited members of a nearby Indian tribe to take part.There were many kinds of food to eat.The meal included wild birds such as ducks, geese and turkeys.That thanksgiving celebration lasted three days.As the American colonies grew, many towns and settlements held thanksgiving or harvest celebrations.[共5题](1)Thanksgiving Day is

holiday.First of all, St.Valentine’s Day is not a holiday from work.No one gets a day off.On Valentine’s Day people usually send romantic cards to someone they love or want to be loved by.The cards are called “valentines”.They are very colorful, often decorated with hearts, flowers, or birds, and have humorous or sentimental verses printed inside.The basic message of the verse is always “Be My Valentine”, “Be My Sweet Heart” or “Lover”.A valentine is often anonymous, or sometimes signed “Guess who”.The person receiving it has to guess who sent it.This can lead to interesting speculation.And that’s half the fun of valentines.One of the symbols of St.Valentine’s Day is the Roman god of Love, called Cupid.Cupid is often printed on the card;he is a winged infant, not wearing anything, poised to shoot his arrow into a heart.He would shoot an arrow of love into a person’s heart to make the person fall in love immediately, maybe with the first person to come along.Sometimes one arrow would go through two hearts, holding them together.So on February 14th not only do we have pictures of the Christian St.Valentine but we also have pictures of the non-Christian Cupid, the Roman god of Love.But it is from the Christians that we get the stories about St.Valentine’s Day that most people have come to believe.One story is about a Christian man whose name sounded something like “Valentine.” He lived around AD 250.At that time the Roman Emperor, Claudius II, refused to allow any Roman soldiers to get married for any reason whatsoever.Christian couples came to Valentine to be married.So Valentine would marry them in a Christian way.He was discovered and put in prison by the Emperor.One tradition says that he wrote notes to his friends by marking on leaves and then throwing them out the window of his prison.And the leaves were shaped like a heart.[共5题](1)St.Valentine’s Day is a holiday for __________.(A)people celebrating the new year’s coming(B)people fooling

telephone may well be one of the minor irritations of life, demanding patience, determination and a strong possibility of failure, together on occasion with considerable unpopularity.The hopeful caller(shall we call him George?)waits till six o’clock in the evening to take advantage of the so-called “cheap rates” for a long-distance call.The telephone box, with two broken panes of glass in the side, stands at the junction of two main roads with buses, lorries and cars roaring past.It is pouring with rain as George joins a queue of four depressed-looking people.Time passes slowly and seems to come to a standstill while the person immediately before George carries on an endless conversation, pausing only to insert another coin every minute or so.Eventually the receiver is replaced and the caller leaves the box.George enters and picks up one of the directories inside, only to discover that someone unknown has torn out the very page he needs.Nothing for it but to dial directory Enquiries, wait patiently for a reply down the number given.At last George can go ahead with his call.Just as he is starting to dial, however, the door opens and an unpleasant-looking face peers in with the demand, “Can’t you hurry up?” Ignoring such barbarity, George continues to dial and his unwanted companion withdraws.At last he hears the burr-burr of the ringing tone, immediately followed by rapid pips demanding his money, but he is now so upset that he knocks down the coins he has placed ready on the top of the box.Having at last located them, he dials again: the pips are repeated and he hastily inserts the coins.A cold voice informs him, “Grand Hotel, Chalfont Wells.” “I’ve an urgent message for a Mr.Smith who is a guest in your hotel.Could you put me through to him? I’m afraid I don’t know his room number.” The response appears less than enthusiastic and a long long silence follows.George inserts more coins.Then the voice informs him, “I’ve been trying to locate Mr.Smith but the hall porter reports having seen him leave about a minute ago.” Breathing heavily, George replaces the receiver, just as the knocking on the door starts again.[共5题](1)The main purpose of the passage is to provide __________.(A)instructions about how to use a public call box(B)advice about how to deal with public telephone problems(C)criticism of the efficiency of telephone system(D)an account of possible annoyances in using a public telephone 你选择的答案: 前次作业时已经做对 [正确] 正确答案:D(2)George can at least be thankful that __________.(A)the telephone itself is working(B)he can use the directory in the box to find the number(C)the call box is in a convenient position(D)he is able to give his message to the hotel receptionist 你选择的答案: 前次作业时已经做对 [正确] 正确答案:A(3)The reason for George having to dial a second time is that __________.(A)he has used up all the money(B)he can’t find the number he wants in the directory(C)he forgets to put the money in the box(D)he has got to find the money to put in the box 你选择的答案: 前次作业时已经做对 [正确] 正确答案:D(4)How is George feeling when he completes his call?(A)He is very disappointed at missing his family and friends.(B)He feels hard to control his annoyance.(C)He is angry with himself for being so stupid.(D)He is depressed at the thought of having to try again to get through.你选择的答案: 前次作业时已经做对 [正确] 正确答案:B(5)Which of the following is NOT true about “cheap rate”?
