2、现在操作系统的两个最基本的特征是并发和资源共享,除此之外,它还具有虚拟性和异步性的特征。
3、从资源管理的角度看,操作系统具有四大功能:处理机管理、存储器管理、设备管理、文件管理,为了方便用户,操作系统还必须提供友好的用户接口。
4、操作系统的基本类型主要有批处理系统、分时系统、实时系统。
5、实现分时系统的关键问题是人机交互,为此必须引入时间片的概念,并采用时间片轮转调度算法。
6、微内核操作系统是建立在层次化结构的基础上的,而且还采用了客户/服务器模式和面向对象开发技术。
7、程序并发执行与顺序执行是相比产生了一些新特征,分进别是间断性、失去封闭性、不可再现性。
8、引入进程的目的是提高资源利用率,引入线程的目的是提高系统的吞吐率。
9、进程由进程控制块、程序段、数据段组成,其中进程控制块是进程存在的唯一标志。
10、由于进程的实质是程序的一次执行,故进程有动态性的基本特征,该特征还表现在进程由创建而产生,由调度而执行,由撤消而消亡,即进程具有一定的生命期。
11、用户为阻止进程继续运行,应利用挂起原语,若进程正在执行,应转变为静止就绪状态;以后,若用户要恢复其运行,应利用激活原语,进程转变为活动就绪状态。
12、同步机制应遵循的准则有空闲让进、忙则等待、有限等待、让权等待。
13、在利用信号量实现进程互斥时,应将临界区置于wait操作和signal操作之间。
14、进程通信的类型有共享存储器、消息系统、管道通信,其中管道通信利用共享文件进行通信。
15、高级高度又称作作业调度,其主要功能是按照一定的算法从外存的后备队列中选若干作业进入内存,并为它们创建进程;低级调度又称为进程调度,其主要功能是按一定算法从就绪队列中选一个进程投入执行。
16、进程调度有抢占调度和非抢占调度两种方式。
17、在抢占调度方式中,抢占的原则有时间片原则、短作业优先、优先权原则。

Reading Comprehension (20×2)Directions: There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are fourchoices marked A, B, C and D. You should decide on the best choice andmark the corresponding letter on the Answer Sheet.Passage 1Some people do not like anything to be out of place. They are never late for work. They return their books to the library on time. They remember people’s birthdays, a nd they pay their bills as soon as they arrive. Mr. Rock is such a person.Mr. Rock works in a bank, and lives on his own. The only family he has is in the next town. His sister lives there with her husband, and her son, Mark. Mr. Rock does not see his sister or her family every year, but he sends them Christmas cards and he has not forgotten one of Mark’s seventeen birthdays.Last week Mr. Rock had quite a surprise. He drove home from the bank at the usual time, driving neither too slowly nor too fast. He parked his car where he always parks it, out of the way of other cars, and went inside to make his evening meal. Straight away, there was a knock at the door. Mr. Rock opened the door only to find a policeman on the door step.“Have I done anything wrong?”Mr. Rock asked himself. “Have I driven on the wrong side of the road? Has there been some trouble at the bank? Have I forgotten to pay an important bill?”“Hello, uncle,” said the policeman. “My name is Mark. I am your nephew.”1. Mr. Rock is a person who does all the following except _______.A.putting things in orderB.going to work earlyC.visiting friends regularlyD.paying the bills in time2. Which of the following is NOT true?A. Mr. Rock lives by himself.B. Mr. Rock’s sister has a family.C. Mr. Rock’s sister lives not very far away.D. Mr. Rock visits his sister quite often.3. According to the passage, which of the following is true?A.H e drove very fast.B.He made his meal after he got into the house.C.He drove very slowly.D.H e parked his car at a wrong place.4. Mr. Rock was surprised to see the policeman because ________.A.s omething was wrong in the bankB.he did not know what to sayC.he did not do anything wrongD.t he policeman wanted to ask him a question5. From the story we can infer that ______.A.M r. Rock had not seen his nephew for a long timeB.Mr. Rock did not like to see the young manC.Mr. Rock was a shy personD.M ark came to visit his uncle regularlyPassage 2If you judge by the number of people who go to see the games and by the number of those who actually play it,basketball is probably the most popular sport in the United States today. It is mainly an indoor game, and the season extends from late autumn, through the winter, to early spring. There are many professional teams; but for the most part, basketball is a school sport. There is hardly a high school or college in the country that does not have its team.In spring and summer, the most popular sport is baseball. During the warm weather, you can see young men and boys playing this game in any part of the country. Radio and television bring the details of the big games to every corner of that land, and the activities of the professional teams are a subject of conversation for Americanseverywhere.In autumn, the most popular sport is football. As you know, this is not the same kind of game that is so popular in other parts of the world. Like basketball and baseball, it is typically American, and those who have never seen it before have difficulty in seeing any sense in it. But for most people the game itself is not so important as the music and the cheering that go with it. On a cool bright autumn afternoon, there is nothing so colorful and exciting as a football game.6. Basketball is probably the most popular sport in America today because_____________.A. it is an indoor gameB. it is a school gameC. most people like to play or watch the gameD. there are many professional teams7. The passage shows that in America___________________.A. almost all the high schools and colleges have their basketball teamsB. every high school doesn’t have its own basketball teamC. no college has its own basketball teamD. some high schools and colleges have their basketball teams8. In spring and summer, you can see young people playing baseball____________.A. in some parts of AmericaB. in a few states of AmericaC. in some schools of AmericaD. everywhere in America9. During the warm weather, Americans often talk about_______________.A. the activities of the professional baseball teamsB. the radio and televisionC. the details of the football matchesD. the details of the big games10. From the passage we know that American football is_______________.A. similar to that in other parts of the worldB. different from that in other parts of the worldC. not so popular as that in other parts of the worldD. as popular as that in other parts of the worldPassage 3A great deal of nonsense is written about the character of a nation, chiefly because many observers, influenced by national pride and prejudices feel irresistibly tempted (诱惑)to generalize(概括)about everything. In a nation of many millions of people, there are bound to be many different kinds: rich and poor, clever and stupid, good and bad, modest and conceited (自满的), patient and impatient, honest anddishonest. Moreover, a nation may develop a sort of collective character in its politics and literature, which is not recognizable in individual people. Generalizations, therefore, tend to be unrealistic, and should be made, and accepted, with caution. One word of warning is necessary. The British people who take up appointments in Asia and Africa are not fully typical of their nation. For one thing, they are usually specialists in one field or another. The average British person is not a specialist, and although he can read and write he is not particularly cultured in the intellectual sense. “Highbrow” is a word very often used by the common people of Britain to describe and condemn any form of intellectual culture.Moreover, the great technical achievements of Europeans do not mean that a European is basically more intelligent than an African or Asian. The achievements are due to the handing down and sharing of knowledge and to organized training and research rather than to mental superiority; and of course, the mere possession of, say, a motor-car or washing machine and the ability to operate it, does not require any understanding of how it works.11. To know the character of a nation, one should _______.A.o bserve the behavior of the leadersB.read the literature of the nationC.never accept any generalizationsD.f orm a sound judgement of everything12. One reason for the difference between the British people working abroad and theaverage person at home is that the former ________.A.a re more intellectually culturedB.have made many foreign friendsC.work much harderD.h old important positions13. According to the author, ______.A.E uropeans are more intelligent than Africans and AsiansB.there is no such a thing as mental superiorityC.Europeans should share their knowledge with Africans and AsiansD.m ental superiority is vital to the scientific progress in Europe14. This passage is written ______.A.t o warn the readers against misunderstanding the British peopleB.to make a brief introduction to different social classes in BritainC.to criticize the nonsense written about BritainD.t o describe the people’s living conditions in Britain15. What does the author imply by writing the last sentence of the passage?A.K nowing how to operate a motor-car or washing machine means a highmental intelligence.B.The technical achievements of Europeans are due to their intelligence.C.Only knowing how to operate some household appliances does not reallymean that they are of real intelligence.D.E uropeans are more intelligent than Africans and Asians because they are ofmental superiority.Passage 4When you take a walk in any of the cities in the West, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reason why people keep a dog has changed. In the old days people used to train dogs to protect themselves against attacks from other beasts. Andlater they came to realize that a dog was not only useful for protection but willing to obey his master. For example, when people used dogs for hunting, the dogwould not eat what was caught without permission.But now people in cities need not protect themselves against attacks of animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery. But the most important reason is for companionship. For a child, a dog is his best friend when he has no friends to play with. For young couples, a dog is their child when they have no children. For old couples, a dog is also their child when their real children have grown up. So the main reason why people keep dogs has changed from protection to friendship.16.According to the passage, in the old days people trained dogs _______ .A.f or protection against robberyB.just for funC.for companionshipD.f or protection against other animals17.The word “companionship” may mean _______.A.w orshipB.treasureC.friendly relationshipD.p artnership18.The dogs were used for hunting because ________ .A.t hey were good huntersB.they obeyed their mastersC.they were useful for protectionD.t hey did not eat other animals19.The most important reason for people to keep dogs now is _______.A.t hey need companionB.they like childrenC.they enjoy huntingD.t hey want to protect themselves20.We can infer (推断) from the passage that ________.A.d ogs can be helpful to those who need companyB.city people always feel lonelyC.dogs can be interestingD.t he city can be a very dangerous placePassage 5As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for healthy mind and body. Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be.A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusualdifficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact, we make choices between “ flight” and “fight” and in more primitive days the choices made the difference between life and death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we can not remove stress from our life (it would be unwise to do so even if we could), we need to find ways to deal with it.21. We are fast losing the art of relaxation because_______.A.t he pace of life is increasingB.we are rushing through our lifeC.we are on the go from morning till nightD.a ll of the above22. According to the writer, the most important character fora manager is _______.A.t o know the art of relaxationB.not to fear stressC.to provide motivation for othersD.t o enjoy good health23. As far as the amount of stress is concerned, _______.A.d ifferent people can withstand different amount of stressB.different people can withstand the same amount of stressC.a man can withstand different amount of stress at different timeD.a man can withstand the same amount of stress at different time24. The phrase “such a reaction” refers to _______.A.t he “fight”B.the “ flight”C.the reaction to high blood pressure and heart diseasesD.t he reaction to stress both chemically and physically25. The a uthor’s idea about stress is possibly ______.A.t o completely remove it from our livesB.to have stronger stress that lasts longerC.to find proper ways to deal with itD.t o be always exposed to huge stressPassage 6No other author in American literature is better known or more loved than Samuel Langhorne Clemens. Born in Missouri in 1835, he grew up on the banks of the Mississippi River and became a riverboat pilot when he was 21 years old. So he adopted the pen name of “Mark Twain”, which was derived from a phr ase meaning “two fathoms deep” used by the boatmen on the Mississippi as they measured the depth of the river. The river environment inspired the two novels which brought him his greatest fame: “Tom Sawyer” and “Huckleberry Finn”. Another book, “Life on th e Mississippi”, told of his adventures on the river boats of that period.It was during the Civil War that Mark Twain’s life as a writer started. At that time he was working as a newspaper man in Nevada and California. His short story,“The Celebrated Jumping Frog of Calaberas County” was a n immediate success and his new career began. “A Million Pond Note” written in 1893 was another well-known short story.In 1870, Mark Twain married Olivia Langdon. He had fallen in love with her picture even before he met her. According to his biographers, his wife had a great influence on Twain’s laterbooks.Mark Twain was also a very successful lecturer. His travels around the country giving talks on a variety of subjects helped make him famous and increased the sale of his books.“Tom Sawyer” and “Huckleberry Finn” are considered Twain’s best works. They are marked by humor and satire and provide his readers with an excellent picture of his era. His last book was completed in 1909, one year before his death. He was 74 years old.26. Samuel Langhorne Clemens adopted the pen name of “Mark Twain”__________.A. when he was 21 years oldB. after he wrote the novel “Life on the Mississippi”C. from a phrase used by the boatmen on the MississippiD. because the boatmen called him “Mark Twain” when he worked as a riverboat pilot27. Mark Twain’s career as a writer began when______________.A. he wrote “A Million Pound Note”B. he was working on the MississippiC. the Civil War broke outD. he was working as a newspaper man28.

The wood belonged to Lord Northwood, a rich gentleman, and Pat had no right to go there, but in it there were swarms of rabbits and flocks of birds that were good to eat, and Pat determined to take the risk. Suddenly he saw the owner, with a group of friends, coming towards him in the wood. There was a look of anger on Lord Northwood’s face as he caught sight of the gun in Pat’s hands. Pat’s heart sank with fear, but he saw there was no hope of escape, so he walked boldly up to the company and said to Lord Northwood, “Good morning, sir, and what has brought you out so early this morning?” Lord Northwood, rather surprised, said he and his friends were taking a little exercise to get an appetite for their breakfast. Then, looking at Pat with suspicion, he said, “But why are you out so early in the morning?” “Well, sir,” said P at, “I just came out to see if I could get a breakfast for my appetite.” The whole crowd burst into laughter at Pat’s readywit, and with a smile Lord Northwood walked on, leaving Pat to try his luck with the rabbits.31. This is a story about _____________.A. a rich man who owned a big woodB. a poor Irishman who lived all by himselfC. a clever man who tried to get something to eat for his breakfastD. an Irish hunter with a large family32.

It was because of his _________ that Pat was left to try his luck.A. boldnessB. calmnessC. obedience (服从, 顺从)D. quickness of mindPassage 8We are all part of history. Our ways of living today will seem strange to our grandchildren. Our clothes, our automobiles, even our kinds of food, will seem very queer to them. “How strange life must have been back in those days!” our grandchildren will say to us.Changes in way of living are an important part of history. Our ancestors lived very differently from the way we live now. And their ancestors seemed strange to them too.History is the story of whatever happened to people before today. Some events were thrilling, and some were sad. Men have been very cruel in wars and revolutions. On the other hand, many men have worked for peace and freedom.Discoveries of new lands have played an important part in history. How interesting those stories of discoveries are! It is fun, too, to read about inventions and the ways in which they have changed people’s lives. Discoveries in science and medicine have made great changes, too.History is the story of presidents and kings, of heroes and villains. It is the story of ordinary people, too. History is everybody’s story!36.We are part of history because ______.A.we are living in the 20th centuryB.we have many grand childrenC.we have strange thingsD.we have a different way of life37.All the following queer things are mentioned in the passage except______.A.clothesB.housingC.automobilesD.foods38.Which of the following is NOT true?A.Our way of life is much the same as our ancestor’s.B.New discoveries have brought about changes.C.Discoveries have played an important part in history.D.History tells us what happened in the past.39.The passage suggests that ______.A.man is always goodB.the changes make people inventC.man enjoys learning about historyD.we do the same as our ancestors40.History is the story about ______.A.ordinary peopleB.heroes and villainsC.kings and presidentsD.all of the abovePassage 9Many people think New York is a noisy city. The noise level comes from having so many people and cars in the same area. Now even the insides of taxis are noisy. When you are get into a taxi, you hear voices saying things such as buckling your seat belt, “ Don’t forget to collect all your belongings.”, and so on.There is a good reason for the messages. There are more than 12 000 cabs in New Y ork, and every year taxis get into more than 15 000 accidents. Every year, about 11 ,000 people get injured in this way.Many people are annoyed by the voices. Cabdrivers in particular dislike the messages. “I play the messages 12 hours aday. I hear the sam e voices 60 times a day. It makes me crazy,” says Amir, a 45-year-old cabdriver. “But if I don’t play the messages, I get fined $100.” A lot of passengers complain, too. “It’s too much noise,” says a passenger. “I asked the driver to turn off the messages,but he said he can’t.”Other people think the voices are a great idea. One taxi driver says, “People l ike to hear the famous voices, and they put on their seat belts more often.” And passengers from out of town really like the idea. “Most of the time, ta xi drivers are in a bad mood,” says Melanie Benton, who visits New York often on business. “It’s nice t o hear a cheerful voice when you get intoa cab.”41.New Y ork is, the passage says, a noisy city because ________.A.New Y ork has so many people in the cityB.people and scientists say soC.there are so many cars in New YorkD.both A and C42.Even the insides of New York taxis are noisy, for ________.A.inside a taxi, you hear loud voices telling messages all the timeB.many people are annoyed by the useful messages heard in the taxiC.taxi drivers are crazy with the noiseD.taxi drivers will get fined if they play the messages43.According to the passage, the good reason for the messages played inside a taxi is________.A.the drivers can’t turn off the voicesB.the messages can help passengers to avoid trafficaccidentsC.many people dislike the messagesD.many drivers like playing them44.From the passage, we may conclude that the author ________.A.hates the messages played inside the taxisB.doesn’t offer any suggestions to solve the proble mC.thinks that taxi drivers should always be happy with the noiseD.is not annoyed by the voices inside the taxis45.The title for the passage might be ________.A.Noise in New Y ork TaxisB.Messages Are GoodC.Drivers and V oicesD.Avoiding Traffic AccidentsPassage 10I see four kinds of pressure working on college students today: economic pressure, parental pressure, peer pressure, and self-induced pressure. It is easy to look around for villains---- to blame the colleges for charging too much money, the professors for assigning too much work, the parents for pushing their children too far, the students for driving themselves too hard. But there are no villains, only victims.They know that entrance into the better schools will be an entrance into the better law firms and better medical practices where they will make a lot of money. They also know that it is very hard to achieve success both in life and in study.The pressure is almost as heavy on students who just want to graduate and get a job. They live in a brutal economy. Along with economic pressure goes parental pressure. Inevitably, the。
