2010-2011学年第二学期汇编试卷A卷答案
《汇编语言程序设计》试卷( A卷)2010-2011学年第2学期计算机学院本科生闭卷考试，考试时间： 2011年7月 2 日专业班级学号姓名一、填空题（共10分，每空1分）1、存储程序和程序控制是计算机工作的基本原理，要执行的程序预先存放在内存中。
CPU当前将要执行的指令的物理地址依据_CS_和_IP/EIP_两个寄存器的内容计算得到。
2、CPU在取到一条指令后，需要对该指令进行译码和执行，此时指令指示器(IP/EIP)会自动加上该指令的代码长度(字节数)_，使其指向该指令的下一条指令。
3、在执行该指令时，若指令不是转移类（包括_条件_转移、无条件转移、子程序调用和返回、软中断调用和返回等）的指令时，就不会额外影响CS 和IP/EIP的值。
这样，取出的下一条指令就在该指令之下，程序将会顺序执行。
4、若该指令是段内子程序调用语句，CPU首先将（IP/EIP）压栈，然后将子程序第一条指令的偏移地址送入到IP/EIP。
这样取下一条指令时，取出的就是子程序中的第一条要执行的指令。
5、若该指令是段内子程序返回指令，CPU将栈顶元素弹出到IP/EIP 。
如果CPU在做上述操作前,栈顶的数据正好是在调用子程序时保存的断点偏移地址，则程序转回到了调用子程序的语句之下。
6、若该指令是JMP WORD PTR[BX]，则该指令被称为无条件段内间接转移指令，转移到的目标指令的偏移地址存放在__DS _ 段中，通过寄存器间接寻址方式取到相应单元的值送给IP 。
二、选择题（共10分，每题1分）1、指令ADD [BX], 20H 的错误原因是___D_____。
(A) BX 不能用于寄存器间接寻址方式(B) 源操作数不能用立即寻址方式(C) 源、目的操作数不能同时为存储器操作数(D) 源、目的操作数类型均不明确2、指令ADD [CX], AL 的错误原因是___A_____。
(A) CX 不能用于寄存器间接寻址方式(B) 源、目的操作数类型不匹配(C) 源、目的操作数不能同时为存储器操作数(D) 源、目的操作数类型均不明确3、指令ADD BX, AL 的错误原因是___B_____。

Reading Comprehension (30%)Directions: There are 3 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D).You should decide on the best choice and mark the correspondingletter on Answer Sheet 2 with a single line through the centre. Questions 46 to 50 are based on the following passage.If you want to teach your children how to say sorry, you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky.If you say to your children “I’m sorry I got angry with you, but …” what follows that “but” can render the apology ineffective: “I had a bad day” or “your noise was giving me a headache ” leaves the person who has been injured feeling that he should be apologizing for his bad behavior in expecting an apology.Another method by which people appear to apologize without actually doing so is to say “I’m sorry you’re upset”; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done.Then there is the general, all covering apology, which avoids the necessity of identifying a specific act that was particularly hurtful or insulting, and which the person who is apologizing should promise never to do again. Saying“I’m useless as a parent” does n ot commit a person to any specific improvement.These pseudo-apologies are used by people who believe saying sorry shows weakness. Parents who wish to teach their children to apologize should see it as a sign of strength, and therefore not resort to these pseudo-apologies.But even when presented with examples of genuine contrition, children still need help to become aware of the complexities of saying sorry. A three-year-old might need help in understanding that other children feel pain just as he does, and that hitting a playmate over the head with a heavy toy requires an apology. A six-year-old might need reminding that spoiling other children’s expectations can require an apology. A 12-year-old might need to be shown that raiding the biscuit tin without asking permission is acceptable, but that borrowing a parent’s clothes without permission is not.46. If a mother adds “but” to an apology, _______.A) she doesn’t feel that she should have apologized。

Perhaps, as a baby, you used to suck(吮吸) your thumb. Of course, you do not do that any more, but you can surely remember your mother‟s efforts to train you. The good habits you now have in such matters as personal cleanliness were part of this early training.We may not suck our thumbs any more, but as we get older, we get other bad habits. We can‟t give them up easily, either. (Anyone who has tried to give up smoking knows this very well!) Each period brings its own problems. In babyhood, it‟s thumb-sucking; in childhood, it‟s nail-biting; in our teens, it‟s smoking; in middle-age, it‟s over-eating, and so on. And if anyone tells you that he has no bad habits, you can be sure that he must have the worst habit of all.56. Generally speaking, a child likes ______.A. sucking thumbsB. biting nailsC. smokingD. eating too much57. According to the passage, now we have good habits such as personal cleanliness, for which webenefit from(受益于) _______.A. the social conditionsB. some strict rulesC. our friends‟ kind helpD. our mothers‟ early training58. At the end of the story the writer says "And if anyone tells you that he has no bad habits, you canbe sure that he must have the worst habit of all". Here what do you suppose the worst habit is?A. Reading.B. Playing.C. Walking.D. Lying.59. Which of the following is NOT true according to the passage?A. It is difficult to get rid of our bad habits.B. At different ages, people have different bad habits.C. Giving up smoking is as difficult as giving up other bad habits.D. Sucking thumbs is a young child‟s bad habit.BThe yearly Academy Awards ceremony was once a private affair. Now, because of television, it is very much a public affair. Hundreds of people gather in Hollywood to see the Oscars presented to outstanding(杰出的) actors, and others involved in the motion picture industry. Millions more watch on television.It all began on May 16, 1929, when 270 men and women sat down to dinner at the Hollywood Roosevelt Hotel. There was no secret about the winners. The names of the winners had been known for months. Janet Gaynor, for example, had won as Best Actress. Douglas Fairbanks presented her with the famous gold statue. The little statue was not then called Oscar. Like a new actor, Oscar was unknown. About six years later, it somehow got that renowned name. A number of explanations have been offered for its origin, but nobody knows the true story for certain.Nowadays the results of the Oscar voting are kept secret. Only two people know the winners before the names are announced at the ceremony. The counting of votes is not done by one group of people but by different groups. Nobody except two members of an accounting(计票) company sees the final results.The information is not kept in open files. Winners‟ names are placed in closed envelopes. The accountants each carry a complete set of envelopes to the ceremony. One set is simply a spare to be used in case(万一) something happens to the other one.60. In Paragraph 2, the underlined word …renowned‟ means _______.A. strangeB. wonderfulC. much-dislikedD. famous61. May 16, 1929 marks _______.A. Douglas Fairbanks‟ first winning of an Academy AwardB. the first time Oscar got its nameC. the first time the Awards were kept secretD. Janet Gaynor‟s recognition as Best Actress62. Two sets of envelopes are prepared for the ceremony _______.A. one for New York, one for HollywoodB. in order to be perfectly safeC. one for the ceremony, one for the newspapersD. just because that is the customCBamboo is one of the nature‟s most surprising plants. Many people call this plant a tree, but it is a kind of grass.Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains(平原).Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables(绳索) that hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong.In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills(钻) can help to make the poor thirsty fields to be watered.63. How is bamboo like grass?A. It is thin and easy to cut.B. It grows everywhere.C. It grows quickly after it‟s cut short.D. It is short and green.64. The sentence “while others may grow to more than 30 centimeters across.” means “some otherbamboo plants may grow to be very _______.”A. shortB. strongC. thickD. tall65. From the text we know ______.A. most people call bamboo plant treesB. a bamboo plant may grow 4.5 meters in three daysC. the bamboo plant changes its colors when it growsD. a bridge held by bamboo cable was built thousands of years ago66. Why did the engineers teach the poor farmers in Africa to make use of bamboo?A. Because it is cheap.B. Because it is colorful.C. Because it drills fast.D. Because it is used by Asians.67. Which of the following is NOT true?A. There are many different kinds of bamboo with different colors.B. Cables made of bamboo can last for over a thousand years.C. Bamboo can be used for buildings, bridges and watering projects(工程).D. Bamboo plants are able to grow well in any part of the world.DIn most towns today, you can see teenagers standing over electronic machines with flashing lights, shooting at spaceships from other planets and dropping bombs on strange monsters(恶魔). The machines have names like Space Warrior, Dark Invader and so on. It used to be believed that damage was done only to those strange visitors from outer space, but now it seems that they are striking back.Many teenagers like electronic games so much that they can‟t stop playing. They spend hours tightly holding the joystick controls and constantly pressing buttons marked “fire”. They develop pains on their fingers because of the constant pressure. They play and play that the pains have no chance to cure properly. The rapid wrist movement required to guide the spaceship across the screen causes another problem: the muscles of the wrist and arm become so inflamed and swollen(充血红肿) that they press against the bones. This condition is what doctors now call “Space Warrior‟s Wrist”.Other strange aches and pains are also likely to affect the elbows and shoulders.Another even more alarming problem is shown by the case of a 17-year-old girl, which was recently reported in the British Medical Journal. She had been playing various kinds of electronic games for more than two hours a day. Her father repaired games and machines and she could use the cassettes and systems in his workshop as often as she liked. One day, after playing a game called Dark Invader, she lost consciousness(晕倒) and fell to the floor.Doctors who examined her found she was suffering from an unusual illness caused by lights flashing at a particular frequency.68. Electronic games are found very popular with _______.A. people living in townsB. students studying in high schoolsC. girls working in their father‟s workshopsD. young people69. The case of a 17-year-old girl given by the writer shows that the writer _______.A. supports playing electronic gamesB. feels very sorry for the girlC. disagreed with young people‟s playing electronic gamesD. feels worried about young people‟s poor he alth70.

They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane —the area least subject to impact —from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000°F. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.51. What does the author say about the black box?A) It ensures the normal functioning of an airplane.B) The idea for its design comes from a comic book.C) Its ability to ward off disasters is incredible.D) It is an indispensable device on an airplane.52. What information could be found from the black box on the Yemeni airliner?A) Data for analyzing the cause of the crash.B) The total number of passengers on board.C) The scene of the crash and extent of the damage.D) Homing signals sent by the pilot before the crash.53. Why was the black box redesigned in 1965?A) New materials became available by that time.B) Too much space was needed for its installation.C) The early models often got damaged in the crash.D) The early models didn't provide the needed data.54. Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?A) To distinguish them from the colour of the plane.B) To caution people to handle them with care.C) To make them easily identifiable.D) To conform to international standards.55. What do we know about the black boxes from Air France Flight 447?A) There is still a good chance of their being recovered.B) There is an urgent need for them to be reconstructed.C) They have stopped sending homing signals.D) They were destroyed somewhere near Brazil.BThere were smiling children all the way. Charily they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Maiaysia. I was moved.I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not particularly relish the long train journey and had brought along a dozen magazines to read and reread. I looked about the train. There was not one familiar face. I sighed and sat down to read my Economics.It was not long before the train was across the Causeway and in Malaysia. Johore Baru was just another city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight, Immediately I came alive; I decided to wave hack.From then on my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time.The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. I looked at the people all around me. They all looked beautiful. When my uncle amved with a smile, I threw my arms around him to give him a warm hug (拥抱). I had never done this before. He seemed surprised and then his weather-beaten face warmed up with a huge smile. We walked arm in arm to his car.I looked forward to the return journey.56.The author expected the train trip to be______________.A. adventurousB. pleasantC. excitingD. dull57. What did the author remember most fondly of her train trip?A. The friendly country people.B. The mountains along the way.C. The crowds of people in the streets.D.

甘肃政法学院2010—2011学年度第二学期《操作系统》A卷评分参考答案一、名词解释（每题2分，共10分）1.操作系统：是管理计算机硬件和软件资源的一批程序的总称，(1分)为计算机扩展提供一个功能平台，是所有软件的基础，为用户使用计算机提供一个透明接口。
(1分)。
2.工作集：在内存管理中，任何程序在局部性调入时，都对内存有一个临界值要求(1分)。
当内存分配小于它时，内存和外存之间的交换频率会急剧增加，而内存分配大于它时，再增加内存分配也不能显著减少交换次数，这个内存要求就称为工作集(1分)。
3.进程：是一个具有独立功能的程序对某个数据集在处理机上执行过程(1分)和资源分配的基本单位(1分)。
5.文件系统：操作系统中与管理文件有关的软件和数据称为文件系统(1分)，它负责为用户建立文件，撤消、读写、修改和复制文件，还负责完成对文件的按名存取和进行存取控制(1分)。
5.设备驱动程序：是驱动物理设备和DMA控制器或I/O控制器等直接进行I/O 操作的子程序的集合(1分)。
负责设置相应设备的有关寄存器值，启动设备进行I/O操作，指定操作的类型和数据流向等(1分)。

简述进程的一般状态及其转换过程，并画出进程状态转换图。
进程的状态一般包括就绪、等待、运行；运行状态的进程由于时间片到或高优先级就绪进程到达就会转入就绪状态，由于等待输入输出数据等事件会转入等待状态；就绪状态的进程由于在就绪队列的最前面，会被调度变为运行态，等待状态的进程由于等待事件的完成会被转入就绪状态。
（3分）2. 什么是请求页式存储管理技术？试说明为什么要引入缺页中断。
请求页式存储管理技术，指在作业或进程开始执行之前（1分）,不把作业或进程的程序段和数据段一次性全部装入内存（1分）,而只装入被认为是经常反复执行和调用的工作区部分,其它部分则在执行过程中动态装入（1分）。
由于请求页式存储管理技术，只将程序和数据的一部分装入内存，在进程执行时，势必有一部分指令和数据没有在内存，当访问这些内容时，必须将内存中的内容交换到外存，然后将外存中的内容装入内存。
这些操作都会引起正在执行的进程转入等待状态，完成内容装入工作后继续执行。
故必须引入缺页中断。
（2分）3．简述陷阱与中断的区别与联系。
中断是指计算机在执行期间，系统内发生了任何非寻常的或非预期的急需处理事件，使得CPU 暂时中断当前正在执行的程序而转去执行相应的事件处理程序，待处理完毕后返回原被中断处继续执行或调度新技术开发区的进程执行的过程。
根据中断源产生的条件，可把中断分为外中断和内中断。
（1分）外中断指来自处理机和内存外部的中断，狭义上一般称为中断。
内中断指来自处理机和内存内部产生的中断，一般称为陷阱。
由此可见，它们都是广义上的中断。
（1分）主要区别是：（3分）（1）陷阱通常由处理机正在执行的现行指令引起，而中断则是由与现行指令无关的中断源引起的。
（2）陷阱处理程序提供的服务为当前进程所用，而中断处理程序提供的服务则不是为了当前进程。
