主觀題
一、簡答題
1.域用戶帳戶和本地用戶帳戶之間的區(qū)別是什么？
答：域用戶帳戶和本地用戶帳戶之間的區(qū)別是：域用戶帳戶建立在域控制器的AD數(shù)據(jù)庫內(nèi)，用戶可以利用域用戶帳戶登錄域，并利用它來訪問網(wǎng)絡(luò)上的資源。當(dāng)用戶帳戶建立在某臺域控制器內(nèi)后，該帳戶會自動復(fù)制到同一域內(nèi)的其他所有域控制器中；本地用戶帳戶建立在Windows 2000獨立服務(wù)器，Windows 2000成員服務(wù)器或Windows 2000 Professional的本地安全數(shù)據(jù)庫內(nèi)，而不是域控制器內(nèi)，用戶可以利用本地用戶帳戶來登錄此計算機(jī)，但是只能訪問這臺計算機(jī)內(nèi)的資源，無法訪問網(wǎng)絡(luò)上的資源
2.網(wǎng)絡(luò)協(xié)議的基本要素是什么？并說明其含義。
答：基本要素：語義、語法、規(guī)則
a)語義（semantics）。涉及用于協(xié)調(diào)與差錯處理的控制信息。b)語法（syntax）。涉及數(shù)據(jù)及控制信息的格式、編碼及信號電平等。定時（timing）：涉及速度匹配和排序等
3.域名系統(tǒng)是如何解釋域名的？
答：從概念上講，域名解析自上而下進(jìn)行，從根服務(wù)器開始直到樹葉上的服務(wù)器。域名解析有兩種方式：
1）反復(fù)解析（iterative solution）：每一次聯(lián)系一個不同的服務(wù)器。遞歸解析（recursive solution）：請求一個名字服務(wù)器系統(tǒng)完成全部解析。2）遞歸解析（recursive solution）：請求一個名字服務(wù)器系統(tǒng)完成全部解析
二、綜合題
1.何謂鏈路的虛聯(lián)接、虛通路和虛通道？ATM虛聯(lián)接是如何建立的？
答：ATM采用面向聯(lián)接的傳輸方式，將數(shù)據(jù)分割成固定長度的信元，通過虛聯(lián)接進(jìn)行交換。
ATM中的虛聯(lián)接由虛通路（VP：Virtual Path）和虛通道（VC：Virtual Channel）組成，分別用VPI和VCI來標(biāo)識。多個虛通道可以復(fù)用一個虛通路，而多個虛通路又可以復(fù)用一條傳輸鏈路、在一個傳輸鏈路上，每個虛聯(lián)接可以用VPI和VCI的值惟一標(biāo)識。
當(dāng)發(fā)送端希望與接收端建立虛聯(lián)接時，它首先通過UNI向ATM網(wǎng)絡(luò)發(fā)送一個建立聯(lián)接的請求。接收端接到該請求并同意建立聯(lián)接后，一條虛聯(lián)接才會被建立。虛聯(lián)接用VPI/VCI來標(biāo)識。
在虛聯(lián)接中，相鄰兩個交換機(jī)間信元的VPI/VCI值保持不變，當(dāng)信元經(jīng)過交換機(jī)時，其信元頭中VPI/VCI值將根據(jù)要發(fā)送的目的地，參照聯(lián)接映像表被映射成新VPI/VCI.這樣，通過一系列VP、VC交換，信元被準(zhǔn)確地傳送到目的地。
2.找出不能分配給主機(jī)的IP地址，并說明原因。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．第三個數(shù)256是非法值，每個數(shù)字都不能大于255 B．第一個數(shù)231是保留給組播的地址，不能用于主機(jī)地址 C．以全0結(jié)尾的IP地址是網(wǎng)絡(luò)地址，不能用于主機(jī)地址 D．以全1結(jié)尾的IP地址是廣播地址，不能用于主機(jī)地址
西安交通大學(xué)網(wǎng)絡(luò)教育學(xué)院
3.某公司需要將5200臺計算機(jī)從120個地點（假定每個地點的計算機(jī)數(shù)量大致上是平均的）連接到網(wǎng)絡(luò)中。為此需要申請一個合法的IP地址。請回答以下問題：
1）該公司需要申請哪一類地址才能滿足要求； 2）這個地址如何劃分為子網(wǎng),分配給120個物理網(wǎng)絡(luò)；
3）這個網(wǎng)絡(luò)中總共可以為多少臺計算機(jī)單獨分配地址；
4）給出地址的子網(wǎng)和主機(jī)部分的地址范圍。
答：1）b類地址空間是216]5200，能夠滿足要求。故申請一個b類地址。
2）120最接近128=27，所以至少從主機(jī)位中借7位來劃分子網(wǎng)。
3）每個子網(wǎng)的主機(jī)位為9位，故每個子網(wǎng)的主機(jī)數(shù)最多可以達(dá)到29-2=510，由于支持128個或126個子網(wǎng)(取決于路由協(xié)議)，所以最大主機(jī)容量是128×510或126×510。4）第一個子網(wǎng)：a.b.0.0~ a.b.1.255 第二個子網(wǎng)：a.b.2.0~ a.b.3.255以此類推，共128個子網(wǎng)。

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題](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.你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：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 你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：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題](1)Besides its basic purpose, Car also serves as a symbol of people’s _________.(A)occupation(B)status(C)character(D)reputation 你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：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 你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：B(3)A serious environmental problem resulting from automobiles is _________.(A)tragic loss of life(B)traffic jams(C)air pollution(D)mental stress 你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：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.你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：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 你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：D 參考答案：
[第四單元];第5小題：D 主旨題。作者以“The automobile has many advantages”開篇，并從運輸功能、經(jīng)濟(jì)作用等方面說明；然后以“In spite of their advantages, ?”引出了汽車帶來的負(fù)面影響。所以最好的標(biāo)題是選項D，“汽車的好處和壞處”。
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題](1)We may conclude, in regard to the author’s development as a writer, that his father _________.(A)made an important contribution

[第四單元];第5小題：A 推斷題。從文章最后一段“?left Harvard, had my plays rejected?”可以推斷作者對于自己的劇作被拒感到沮喪；從“?in which all the houses had that familiar, smoked brick and cream-yellow-plaster look”可以推斷他所居住的房子也是這樣的；從“?in the autumn of 1926”以及“I began to write my first book?”
可以推知在1926年作者開始寫第一本書。而選項A在文章中是沒有根據(jù)的。所以選A，“他失去了決定前進(jìn)方向的能力。”

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題](1)Thanksgiving Day is originally celebrated by people for

complicated but interesting 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題](1)St.Valentine’s Day is a holiday for __________.(A)people celebrating the new

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題](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 你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：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 你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：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 你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：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.你選擇的答案： 前次作業(yè)時已經(jīng)做對 [正確] 正確答案：B(5)Which of the following is NOT true about “cheap rate”?
