The ( 2 ) a meal is cooked and served is the most important and an ( 3 ) served meal will often improve a child’s appetite. Never ask a child ( 4 ) he likes or dislikes a food and never ( 5 ) likes and dislikes in front of him or allow ( 6 ) else to do so. If thefather says he hates fat meat or the mother ( 7 ) vegetables in the child’s hearing, he is ( 8 ) to copy this procedure. Take it ( 9 ) granted that he likes everything and he probably ( 10 ). Nothing healthful should be omitted from the meal because of a ( 11 ) dislike. At meal times it is a good ( 12 ) to give a child a small portion and let him ( 13 ) back for a second helping rather than give him as ( 14 ) as he is likely to eat all at once. Do not talk too much to the child ( 15 ) meal times, but let him get on with his food; and do not ( 16 ) him to leave the table immediately after a meal or he will ( 17 ) learn to swallow his food ( 18 ) he can hurry back to his toys.

For those who do want a ( 3 ) of their own, opportunities are limited, and working women usually have to ( 4 ) for lower wages, fewer promotions, less responsible ( 5 ).In America, on the other hand, most women, ( 6 ) wives and mothers, work most of their lives, but ( 7 ), few have had real careers. As in Japan most fields are ( 8 ) by men and opportunities for women have been ( 9 ), salaries low, chances for advancement ( 10 ) American women work mainly because they ( 11 ), in these days of inflation and luxury living.

So American women actually have two jobs: one nine-to-five position outsidethe home, and ( 14 ) round-the-clock-in-the-home-job ( 15 ) wife, house-maid, cook, and nurse.One of the main goals of the modern women’s liberation movement, which started ( 16 ), was to eliminate sex discrimination in the work force, and to ( 17 ) careers for women that were previously ( 18 ) for men.

Du ring recent years we have heard much about “race”: how this race does certain things and that race believes certain things and so on. Yet, the ( 1 ) phenomenon of race consists of a few surface indications.We judge race usually ( 2 ) the coloring of the skin: a white race, a brown race, a yellow race and a black race. But ( 3 ) you were to remove the skin，you could not ( 4 ) anything about the race to which the individual belonged. There is ( 5 ) in physical structure, the brain or the internal organs to ( 6 ) a difference.There are four types of blood. ( 7 ) types are found in every race, and no type is distinct to any race. Human brains are the ( 8 ). No scientists could examine a brain and tell you the race to which the individual belonged. Brains will ( 9 ) in size, but this occurs within every race.( 10 ) does size have anything to do with intelligence. The largest brain ( 11 ) examined belonged to a person of weak ( 12 ). On the other hand, some of ourmost distinguished people have had ( 13 ) brains.Mental tests which are reasonably ( 14 ) show how no differences in intelligence between races. High and low test results both can be recorded by different members of any race. ( 15 ) equal educational advantages, there will be no difference in average standings, either on account of race or geographical(地理的)location. Individuals of every race ( 16 ) civilization to go backward or forward. Training and education can change the response of a group of people, ( 17 ) enable them to behave in a ( 18 ) way.The behaviors and ideals of people change according to circumstances, but they can always go back or go on to something new ( 19 ) is better and higher than anything ( 20 ) the past.D.1.

( 2 ), the answer to both these questions is yes. ( 3 ) some extent our intelligence is given us at birth, and no ( 4 ) of special education can make a genius ( 5 ) a child born with low intelligence. ( 6 ), a child who lives in a boring environment will ( 7 ) his intelligence less than one who lives in rich and ( 8 ) surroundings. Thus the limits of a person's intelligence are fixed at birth, ( 9 ) whether or not he reaches those limits will depend on his environment. This ( 10 ), now held by most experts, can be supported in a number of ways.( 11 ) is easy to show that intelligence is to some extent something we are born ( 12 ). The closer the blood relationship between two people, the closer they are ( 13 ) to be in intelligence. Thus ( 14 ) we take two unrelated people at random from the population, it is likely that their degrees of ( 15 ) will be completely different. If on the other hand we take two ( 16 ) twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, ( 17 ) have similar intelligence, and this clearly suggests that intelligence depends on birth. Imagine now ( 18 ) we take two identical twins and put them in different environments. We would soon ( 19 ) differences in intelligence developing, and this indicates that ( 20 ) as well as birth plays a part.D.1. A. wise B. intelligent C. bright D. stupidC.2. A. By no means B.

So ( 1 ), many people are concerned ( 2 ) the question: Am I getting enough vitamins, and am I getting the ( 3 ) kind?Even though very small ( 4 ) of each vitamin are enough for the ( 5 ) of the body, the worry people have about vitamins has some basis. And this has to do ( 6 ) their diet---the food they take in. A person eating a good ( 7 ) of foods get all the vitamins now ( 8 ) to be needed.The problem is that there are many people ( 9 ) don’t choose foods wisely. So the answer ( 10 ) this question is: No ( 11 ) vitamins are needed, ( 12 ) you eatproper foods. In fact, many of the vitamins cannot be ( 13 ) in the body, so when extra vitamins are taken in, the body simply gets rid of them. It is even ( 14 ) to put too much of certain vitamins into the body. This has been found to be true ( 15 ) vitamin A and D, when large amounts are taken ( 16 ).What foods supply what vitamins? Here is a quick ( 17 ) idea. Vitamin A for the ( 18 ) of the eyes, skin, teeth, and bones, is found in green vegetables, fruits, eggs, liver and butter. Vitamin B1 which ( 19 ) the nervous and digestive ( 20 ) and prevents certain diseases, is found in cereals, pork and liver. VitaminB2 is found in milk, eggs, green vegetables and meats. Vitamin C, which helps bones and teeth, is found in tomatoes, certain fruits and vegetables. These are only a few of the most important vitamins the body needs.B.1.

Most months have a national holiday that has been arranged to be celebrated on a Monday. The holidays have all been decided to be celebrated on a Monday so that the workers may have 3-day weekends--- that is, Saturday, Sunday and Monday in order to rest or travel or do things with their families. Major holidays in the United States such as N ew Year’s Day or Christmas Day or the day, when we remember the first settlers of the United States, called Thanksgiving Day are celebrated all over the country. During theseholidays most businesses close and the workers stay home and celebrate with their family.Vacation can be from 2 weeks a year to 4 weeks a year. This usually depends on how long you’ve been working for a company, what type of position you have, whether you have a very high position or a very important position and it’s difficult to fin d someone to replaceyou. In this case, you might take a few days at a time rather than taking one month all at once. Usually the more time you spend working for a company, the more time you may get for vacation.1. The government of the United States makes it a rule for workers to have a ___ weekend almost once a month.A. 1-dayB. 2-dayC. 3-dayD. 4-day2. Workers in the United States sometimes work from___.A. Monday to SaturdayB. Tuesday to SundayC. Thursday to FridayD. Tuesday to Friday3. Which statement is not true according to this passage?A. Only a few shops remain open on New Years Day.B. Most of the workers needn’t work on Christmas Day.C. Days on vacation must be more than all the holidays in a year.D. All the workers have a half month vacation at last.4. The reason why someone has to divide his vacation into several parts is that ___.A. no one can be found to take his placeB. he hasn’t a most high positionC. he plays an important role in his workD. he hasn’t been working for his co mpany for a long time5. Which of the following is the best title for this passage?A. Holidays in the United StatesB. Vacation in the United States.C. How do the workers spend their holidays.D. Something about the holidays and vacation in the U.S..82.Why don’t birds get lost in their long migratory flights? Scientists have been puzzled o ver this question for many years. Now they’re beginning to fill in the blanks. Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly at night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the star in their long-distance flights.One such bird---a warbler(鸣禽)---had spent its lifetime in a cage and never flown under the natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in theposition of the make-believe stars caused a change in the direction of his flight. Scientists think that warbler, when flying in daylight, use the sun for guidance. But the stars are apparently their principal means of navigation. What do they do when the stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it’s too dark to see the se, the warblers circle helplessly, unable to get their bearings.1. The reason why birds don’t get lost in migratory flightsA. have been known to scientists for years .B. have only recently been discovered.C. are known by everyone.D. will probably remain a mystery.2. The experiment with the warbler indicated thatA. birds have to be taught to navigate.B. a bird that has been caged will not migrate.C. some birds cannot fly at night.D. some birds seem instinctively to follow the star when flying at night.3. Under artificial stars, the bird in the cageA. tried to fly in the same direction as birds not caged .B. changed direction when the position of the stars was changed.C. would not fly at all.D. both A and B.4. Warblers migrateA. from North American to the Falkland Islands.B. only once during their lifetime.C. using what is apparently an inborn navigational ability.D. when they are freed from their cages.5. This article is a good example of the way scientistsA. jump to conclusion.B. discover workable answers to general questions by studying particular cases.C. formulate a law and then carry out investigation.D. are frustrated by the habits of animals.83.Social customs and ways of behaving change. Things which were considered impolite many years ago are now acceptable. Just a few years ago, it was considered impolite behavior for a man to smoke on the street. No man who thought of himself as being a gentleman would make a fool of himself by smoking when a lady was in a room.Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn’t it matter? What about table manners? Should you use both hands when you are eating? Should you leave one on your lap, or on the table?。

A film crew was at the Circle Five Ranch to film a Marlboro commercial. This was in 1868, before they prohibited cigarette ads from American television. Darrell Winfield was watching the crew set up the equipment. The scene included an actor crossing a river on horseback, but when the time came to shoot, the man was too drunk to ride. Someone from the crew saw Winfield and asked him if he would ride the horse for 50 dollars. "Hell," said Winfield, "for 50 bucks, I'll jump that damn horse over the moon!"To people in many countries, Winfield is just a familiar but nameless face, a simple cowboy with an advertising message about a connection between the West and a brand of cigarettes. Few people know that he is 55, a family man who's been married to the same woman for 37 years and has 5 children and 7 grandchildren. Most surprisingly, he's a real, working cowboy who raises horses in his ranch in Wyoming.One of the most striking things about the Marlboro Man is that success hasn't changed him much. He says that complete strangers sometimes come up to him and say, "I've met you,know you from somewhere.

Seven others were so badly damaged that their owners had to leave them, and fifteen others had broken windows or torn roofs. One person was killed, several were badly injured and taken to hospital, and a number of other people received smaller injuries. Altogether over two hundred people were homeless as a result of the storm.A farmer, Mr. C. Y. Tan, said that the storm began early in the morning and lasted for over an hour."I was in the kitchen with my wife and children," he said, "when we heard a loud noise. A few minutes later our house fell down on top of us, we managed to climb out but then I saw that one of my children was missing. I went back inside and found him, safe but very frightened."Mrs. Woo Mei Fong said that her husband had just left for work when she noticed that her house was shaking. She rushed outside immediately with her children."There was no time to take anything," she said. "A few minutes later, the roof came down."Soldiers helped to bring people out of the flooded area and the Welfare Department provided food, clothes and shelter.(1)、Some of the people were taken to hospital because they had been badly injured.A：TB：F答案：A(2)、When the storm first began, Mr. Tan was inside his house.A：TB：F(3)、When Mr. Tan's house fell down, only one of his children was inside it.A：TB：F答案：A(4)、Mrs. Woo and her family escaped injury because her husband had gone to work.A：TB：F答案：B(5)、The best title for the passage would be "A Terrible Storm."A：TB：F答案：AIn 1933 an unknown American called Clarence Nash went to see the filmmaker Walt Disney. He had an unusual voice and he wanted to work in Disney's cartoon（动画片）film for children. When Walt Disney heard Nash's voice, he said,"Stop! That's our duck!"The duck was the now-famous Donald Duck, who first appeared in 1934 in the film The Wise Little Hen. Donald lived in an old houseboat and wore his sailor jacket and hat. Later that year he became a star after an eight-minute Mickey Mouse film. The cinema audience liked him because he was lazy and greedy, and because he lost his temper very quickly. And they loved his voice when he became angry with Mickey's eight nephews. Soon Donald was more popular than Mickey Mouse himself, probably because he wasn't a goody-goody like Mickey.In the 1930s, 40s and 50s Donald and his friends Mickey, Goofy and Pluto made hundreds of Disney cartoons. He also made educational films about the place of the USA in the world and safety in the home. Then in 1966 Donald Duck and his voice disappeared---there were no more new cartoons.Clarence Nash died in February, 1985. But today's children can still see the old cartoons on television and hear that famous voice.(1)、Walt Disney made Donald Duck film.A：TB：F答案：A(2)、The first Donald Duck film was made in 1934.A：TB：F答案：A(3)、Clarence Nash was a film-maker.A：TB：F答案：B(4)、The underlined word "audience" in the second paragraph means readers.A：TB：F答案：B(5)、The underlined word "goody-goody" in the second paragraph means a person who likes to appear to be faultless in behavior.A：TB：F答案：A全套完整题库，全中文翻译内容，复习更方便，考前独家提供简化版本，助您快速通过，全程免费答疑。

If you live in a town, it is often faster than a car and you don't have to worry about parking. You leave it anywhere. As it has a seat at the back and a basket at the front, I can take my little daughter to school, to the library, to the shops, to anywhere.I use it most in summer when the weather is warm and dry. It can be very unpleasant in winter when it is cold and the rain is heavy.You must, of course, be careful on a bicycle. Accidents are not the only problem, though. One day I went shopping and came back to find my front wheel missing. It was a long walk to the bicycle shop. Now I have three strong locks.My husband uses my bicycle sometimes for short journeys. He says it is better than waiting for a bus. He still uses his car for longer journeys, but I think that all day's sitting down is making him fat and lazy. On my bicycle I get a lot of exercises and fresh air, and this makes me feel a lot younger.6.The writer's husband bought her a new car two years ago.A.TB.F答案：B7.A bike is better than a car because it is much cheaper.A.TB.F答案：B8.The writer often uses her bike in summer.A.TB.F答案：A9.You must be careful when you ride a bike, for there are some problems.A.TB.F答案：A10.Riding a bike is a good exercise and it can make you feel younger.A.TB.F答案：A奥鹏远程教育、网络教育“大学英语B、计算机应用基础”统考题库最新整版全套复习题库，内容全面、排版清晰、题题精选、高效通过，无需基础，多加复习即可一次通过；此为模拟试题，非题库，如需题库请+Q：2 6 9 0 4 1 7 1 6；When John and Victoria Falls arrived in New York City for one-year stay, they did not bring very many things with them. They had planned either to live in a furnished apartment or to buy used furniture. But they soon learned about a new system that more and more people are using. The renting of home furnishings (bed, tables, dishes, and so on) has become one of Ameri ca’s fastest growing businesses.What kinds of people rent their home furnishings instead of buying them? People who are international business or government officials, foreign students, airline workers, young married couples - people whose job or business may force them to move frequently from one city to another. They save a lot of trouble and the cost of moving their furniture each time. They simply rent new furniture when they reach their new homes. Young people with little money do not want to buy cheap furniture that they may soon dislike. They prefer to wait until they have enough money to buy furniture they really like. Meanwhile, they find they can rent better quality furniture than they could afford to buy.One family, who now have a large, beautiful home of their own, liked their rented furniture so much that they decided to keep renting it instead of buying new things.

For those who do want a ( 3 ) of their own, opportunities are limited, and working women usually have to ( 4 ) for lower wages, fewer promotions, less responsible ( 5 ).In America, on the other hand, most women, ( 6 ) wives and mothers, work most of their lives, but ( 7 ), few have had real careers.

Yet, the ( 1 ) phenomenon of race consists of a few surface indications.We judge race usually ( 2 ) the coloring of the skin: a white race, a brown race, a yellow race and a black race. But ( 3 ) you were to remove the skin，you could not ( 4 ) anything about the race to which the individual belonged. There is ( 5 ) in physical structure, the brain or the internal organs to ( 6 ) a difference.There are four types of blood. ( 7 ) types are found in every race, and no type is distinct to any race. Human brains are the ( 8 ). No scientists could examine a brain and tell you the race to which the individual belonged. Brains will ( 9 ) in size, but this occurs within every race.( 10 ) does size have anything to do with intelligence. The largest brain ( 11 ) examined belonged to a person of weak ( 12 ). On the other hand, some of our most distinguished people have had ( 13 ) brains.Mental tests which are reasonably ( 14 ) show how no differences in intelligence between races. High and low test results both can be recorded by different members of any race. ( 15 ) equal educational advantages, there will be no difference in average standings, either on account of race or geographical(地理的)location.Individuals of every race ( 16 ) civilization to go backward or forward.

( 2 ), the answer to both these questions is yes. ( 3 ) some extent our intelligence is given us at birth, and no ( 4 ) of special education can make a genius ( 5 ) a child born with low intelligence. ( 6 ), a child who lives in a boring environment will ( 7 ) his intelligence less than one who lives in rich and ( 8 ) surroundings. Thus the limits of a person's intelligence are fixed at birth, ( 9 ) whether or not he reaches those limits will depend on his environment. This ( 10 ), now held by most experts, can be supported in a number of ways.( 11 ) is easy to show that intelligence is to some extent something we are born ( 12 ). The closer the blood relationship between two people, the closer they are ( 13 ) to be in intelligence. Thus ( 14 ) we take two unrelated people at random from the population, it is likely that their degrees of ( 15 ) will be completely different. If on the other hand we take two ( 16 ) twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, ( 17 ) have similar intelligence, and this clearly suggests that intelligence depends on birth. Imagine now ( 18 ) we take two identical twins and put them in different environments. We would soon ( 19 ) differences in intelligence developing, and this indicates that ( 20 ) as well as birth plays a part.1. A. wise B. intelligent C. bright D. stupid=D2. A. By no means B.

Vitamins are a group of substances found in food. The body needs them for life and health. So ( 1 ), many people are concerned ( 2 ) the question: Am I getting enough vitamins, and am I getting the ( 3 ) kind?Even though very small ( 4 ) of each vitamin are enough for the ( 5 ) of the body, the worry people have about vitamins has some basis. And this has to do ( 6 ) their diet---the food they take in. A person eating a good ( 7 ) of foods get all the vitamins now ( 8 ) to be needed.The problem is that there are many people ( 9 ) don’t choose foods wisely. So the answer ( 10 ) this question is: No ( 11 ) vitamins are needed, ( 12 ) you eat proper foods. In fact, many of the vitamins cannot be ( 13 ) in the body, so when extra vitamins are taken in, the body simply gets rid of them. It is even ( 14 ) to put too much of certain vitamins into the body. This has been found to be true ( 15 ) vitamin A and D, when large amounts are taken ( 16 ).What foods supply what vitamins? Here is a quick ( 17 ) idea. Vitamin A for the ( 18 ) of the eyes, skin, teeth, and bones, is found in green vegetables, fruits, eggs, liver and butter. Vitamin B1 which ( 19 ) the nervous and digestive ( 20 ) and prevents certain diseases, is found in cereals, pork and liver. VitaminB2 is found in milk, eggs, green vegetables and meats.

Most months have a national holiday that has been arranged to be celebrated on a Monday. The holidays have all been decided to be celebrated on a Monday so that the workers may have 3-day weekends--- that is, Saturday, Sunday and Monday in order to rest or travel or do things with their families. Major holidays in the United States such as New Year’s Day or Christmas Day or the day, when we remember the first settlers of the United States, called Thanksgiving Day are celebrated all over the country. During these holidays most businesses close and the workers stay home and celebrate with their family.Vacation can be from 2 weeks a year to 4 weeks a year. This usually depends on how long you’ve been working for a company, what type of position you have, whether you have a very high position or a very important position and it’s difficult to find someone to replaceyou. In this case, you might take a few days at a time rather than taking one month all at once. Usually the more time you spend working for a company, the more time you may get for vacation.1. The government of the United States makes it a rule for workers to have a ___ weekend almost once a month.=CA. 1-dayB. 2-dayC. 3-dayD. 4-day2. Workers in the United States sometimes work from___.=DA.

Which of the following is the best title for this passage?=DA. Holidays in the United StatesB. Vacation in the United States.C. How do the workers spend their holidays.D. Something about the holidays and vacation in the U.S..82.Why don’t birds get lost in their long migratory flights? Scientists have been puzzled over this question for many years. Now they’re beginning to fill in the blanks.Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly at night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the star in their long-distance flights.One such bird---a warbler(鸣禽)---had spent its lifetime in a cage and never flown under the natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the make-believe stars caused a change in the direction of his flight.Scientists think that warbler, when flying in daylight, use the sun for guidance. But the stars are apparently their principal means of navigation. What do they do when the stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it’s too dark t o see these, the warblers circle helplessly, unable to get their bearings.1. The reason why birds don’t get lost in migratory flights=BA. have been known to scientists for years .B. have only recently been discovered.C. are known by everyone.D. will probably remain a mystery.2. The experiment with the warbler indicated that=DA. birds have to be taught to navigate.B. a bird that has been caged will not migrate.C. some birds cannot fly at night.D. some birds seem instinctively to follow the star when flying at night.3. Under artificial stars, the bird in the cage=DA. tried to fly in the same direction as birds not caged .B. changed direction when the position of the stars was changed.C. would not fly at all.D. both A and B.4. Warblers migrate=CA. from North American to the Falkland Islands.B. only once during their lifetime.C. using what is apparently an inborn navigational ability.D. when they are freed from their cages.5. This article is a good example of the way scientists=BA. jump to conclusion.B. discover workable answers to general questions by studying particular cases.C. formulate a law and then carry out investigation.D. are frustrated by the habits of animals.83. Social customs and ways of behaving change. Things which were considered impolite many years ago are now acceptable. Just a few years ago, it was considered impolite behavior for a man to smoke on the street. No man who thought of himself as being a gentleman would make a fool of himself by smoking when a lady was in a room.Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn’t it matter? What about table manners? Should you use both hands when you are eating? Should you leave one on your lap, or on the table?The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a woman or offer their seat to a woman, and so will most Americans. Promptness is important both in England and in America. That is, if a dinner invitation is for 7 o’clock, the dinner guest either arrives close to that time or calls up to explain his delay.The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable, especially if they are your guests. There is an old story about a man who gave a formal dinner party. When the food was served, one of the guests started to eat his peas with a knife. The other guests were amused or shocked, but the host calmly picked up his knife and began eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.1. If one has accepted a dinner invitation, what should he do if he is to be late for the dinner?=DA. He should find an excuse.B. He should ask for excuse.C. He should say “Sorry”.D. He should telephone to explain his being late.2. “It would have been bad manners to make his guests feel foolish or uncomfortable.” “Bad manners: means ___.=CA. uglyB. dishonestC. impoliteD. shameful3. Which of the following do you think is the best title for this passage?=AA. Social Customs and BehaviorB. Social lifeC. American and British CustomsD. Promptness Is Important4. According to the text, the best host ___.=AA. tries his best to make his guests feel comfortableB. makes his guests feel excitedC. tries to avoid being naughty to his guestsD. tries to avoid being foolish。

网络重点课后题答案

1-10 试在下列条件下比较电路交换和分组交换。

要传送的报文共x（bit），从源站到目的站共经过k 段链路，每段链路的传播时延为d（s），数据率为C（bit/s）。

在电路交换时电路的建立时间为s（s）。

在分组交换时分组长度为p（bit），且各结点的排队等待时间可忽略不计。

问在怎样的条件下，分组交换的时延比电路交换的要小？答：对电路交换，当t=s 时，链路建立；当t=s+x/C，发送完最后一bit；当t=s+x/C+kd，所有的信息到达目的地。

对分组交换，当t=x/C，发送完最后一bit；为到达目的地，最后一个分组需经过k-1 个分组交换机的转发，每次转发的时间为p/C，所以总的延迟= x/C+(k-1)p/C+kd所以当分组交换的时延小于电路交换x/C+(k-1)p/C+kd＜s+x/C+kd 时，(k-1)p/C＜s1-11 在上题的分组交换网中，设报文长度和分组长度分别为x 和（p+h）（bit），其中p 为分组的数据部分的长度，而h 为每个分组所带的控制信息固定长度，与p 的大小无关。

通信的两端共经过k 段链路。

链路的数据率为b（bit/s），但传播时延和结点的排队时间均可忽略不计。

若打算使总的时延为最小，问分组的数据部分长度p 应取为多大？答：分组个x/p，传输的总比特数：(p+h)x/p源发送时延：(p+h)x/pb最后一个分组经过k-1 个分组交换机的转发，中间发送时延：(k-1)(p+h)/b总发送时延D=源发送时延+中间发送时延D=(p+h)x/pb+(k-1)(p+h)/b令其对p 的导数等于0，求极值p=√hx/(k-1)2-06 数据在信道中的传输速率受哪些因素的限制？信噪比能否任意提高？香农公式在数据通信中的意义是什么？“比特/每秒”和“码元/每秒”有何区别？答：数据在信道中传输受到信道的带宽和信道信噪比的影响，信道的带宽或信道中的信噪比越大，则信息的极限传输速率就越高。

Now teleshopping is starting in Europe. In a number of European countries，people can turn on their TVs and shop for clothes，jewelry，food，toys，and many other things.Teleshopping is becoming popular in Sweden，for example. The biggest Swedish company sells different kinds of things on TV in 15 European countries，and in one year it made $100 million. In France there are two teleshopping channels，and the French spend about $20 million a year to buy things through those channels.In Germany，until last year teleshopping was only possible on one channel for 1 hour every day. Then the government allowed more teleshopping. Other channels can open for telebusiness，including the largest American teleshopping company and a 24-hour teleshopping company. German businesses are hoping this new teleshopping will help them sell more things.Some people like teleshopping because it allows them to do their shopping without leaving their homes. With all the problems of traffic in the cities，this is an important reason. But at the same time，other Europeans do not like this new way of shopping. They can do teleshopping "junk on the air". Many Europeans usually worry about the quality of the things for sale on TV. Good quality is important to them，and they believe they cannot be sure about the quality of the things on TV.The need for high quality means that European teleshopping companies will have to be different from the American companies. They will have to be more careful about the quality of the things they sell. They will also have to work harder to sell things that the buyers cannot touch or see in person. (1)、Teleshopping is cheap in Europe. _________A：TB：F答案：B(2)、People like teleshopping because it is easier. _________A：TB：F答案：A(3)、Some Europeans don't like teleshopping because they don't watch TV. _________A：TB：F答案：B(4)、In Germany，teleshopping may have fewer buyers. _________A：TB：F答案：B(5)、The best title of this passage is " Teleshopping in Europe" _________.A：TB：F答案：A2、Laws have been written to govern the use of American National Flag, and to ensure proper respect for the flag. Custom has also governed the common practice in regard to its use. All the armed services have precise regulations on how to display the national flag. This may vary somewhat from the general rules. The national flag should be raised and lowered by hand. Do not raise the flag while it is folded. Unfold the flag first, and then hoist it quickly to the top of the flagpole. Lower it slowly and with dignity. Place no objects on or over the flag. Do not use the flag as part of a costume or athletic uniform. Do not print it upon cushions, handkerchiefs, paper napkins or boxes. A federal law provides that the trademark cannot be registered if it comprises the flag, or badgers of the US. When the flag is used to unveil a statue or monument, it shouldn't serve as a covering of the object to be unveiled. If it is displayed on such occasions, do not allow the flag to fall to the ground, but let it be carried high up in the air to form a feature of the ceremony. Take every precaution to prevent the flag from soiled. It should not be allowed to touch the ground or floor, nor to brush against objects.(1)、How do Americans ensure proper respect for the national flag? _________A：By making laws.B：By enforcing discipline.C：By educating the public.D：By holding ceremonies.答案：A(2)、What is the regulation regarding the raising of the American National Flag? _________A：It should be raised by soldiers.B：It should be raised quickly by hand.C：It should be raised only by Americans.D：It should be raised by mechanical means.答案：B(3)、How should the American National Flag be displayed at an unveiling ceremony? _________ A：It should be attached to the status.B：It should be hung from the top of the monument.C：It should be spread over the object to be unveiled.D：It should be carried high up in the air.答案：D(4)、What do we learn about the use of the American National Flag? _________ A：There has been a lot of controversy over the use of flag.B：The best athletes can wear uniforms with the design of the flag.C：There are precise regulations and customs to be followed.D：Americans can print the flag on their cushions or handkerchiefs.答案：C(5)、What is Americans' attitude towards their National Flag? _________A：Arbitrary.B：Respect.C：Happy.D：Brave.答案：B三、词汇与语法1、-- Is this your shoe?-- Yes, but where is ________?A：the other oneB：other oneC：another oneD：the others答案：A2、About 40,000 years ago, the sea was _______ 40 meters below today's level.

They are ways of showing kindness.My husband，Bob，is a pilot，and one day we were invited to a potluck (百味餐) at his flying squadron(飞行中队). The noisy room was filled with mouthy kids and their chatting moms and dads. Our son，Daniel, was only two years old. We let him play with the other kids because it was a safe environment.After a while，he came back with a package of peanut butter crackers and proudly held them out to us. A pilot who asked “Do you know whose this little boy is?”followed him.“He is mine,” I answered, wondering what Daniel might hav e done.“Well,” replied the pilot, “I've been passing out crackers to the kids for almost two hours，and your son is one of the youngest guys I gave them to. He's the only one who said 'Thank you'. What he did makes me pleased.”Daniel smiled and proudly repeated，“Thank you.”6.Pilots and their family were invited to the potluck.A.TB.F答案：A7.Daniel felt very excited when he showed his crackers to his parents.A.TB.F答案：B8.For nearly two hours at least, the pilot served at the party when he found Daniel.A.TB.F答案：A9.Only one kid said “Thank you” to the man when he gave the kids crackers.A.TB.F答案：A10.The pilot felt surprised when he heard the boy said “Thank you”.A.TB.F答案：Bthose of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, and Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.11.What makes a scientist according to the passage? ________A.The tools he uses.B.The way he uses his tools.C.His ways of learning.D.The various tools he uses.答案：B12.The underlined part in the passage shows_______.A.the importance of informationB.the importance of thinkingC.the difference between scientists and ordinary peopleD.the difference between carpenters and people with other jobs答案：C13.A sound scientific theory should be one that _________.A.works not only under one set of conditions at one time, but also under the same conditions at other timesB.does not allow any changes even under different conditionsC.can be used for many purposesD.leaves no room for improvement答案：A14.The author quotes the case of Albert Einstein to illustrate __________.A.that measurements are keys to success in scienceB.that accuracy of mathematicsC.that investigations are important in scienceD.that the mathematical calculations may test his investigations答案：C15.What is the main idea of the passage? ________A.The theory of relativity.B.Exactness is the core of science.C.Scientists are different from ordinary people.D.Exactness and ways of using tools are the keys to the making of a scientist. 答案：D三、词汇与语法16.The man ______Mary was so tall that she could hardly see the show.A.in front ofB.in the front ofC.at the back ofD.at the beginning of答案：A17.Jane likes singing.
