(从下面方框中选择合适的词或表达,以其适当的形式填空,共10分, 每空2分)high-level language assembly language writtenmachine language notationA programming language, designed to facilitate the communication between human and computers, is a _ notation _ for describing computation in readable form. There are 3 levels of programming languages, they are_ machine language _ , which can be run directly by computer; ___ assembly language __ and _ high-level language _. There are different high-level programming languages. Fortunately, most of them have many kinds of construct in common and vary only in the way that these must be _ written __ . Therefore, first thing to be decided about a task is to choose which programming language is best suited for the job.Passage AThe central processing unit (CPU) is the heart of the computer systems. Among other things, its configuration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, while its speed and capacity have increased tremendously. Indeed, these changes have resulted in microcomputers that are small enough to fit on your desk or your lap.The CPU comprises the control unit and the arithmetic / logic unit (ALU). The control unit is responsible for directing and coordinating most of the computer systems activities. It determines the movement of electronic signals between main memory and the arithmetic/logic unit, as well as the control signals between the CPU and input/output devices.The ALU performs all the arithmetic and logical (comparison) functions —that is, it adds, subtracts, multiplies, divides, and does comparisons. These comparisons, which are basically “less than”, “greater than”, and “equal to”, can be combined into several common expressions, such as “greater than or equal to”. The objective of most instructions that use comparisons is to determine which instruction should be executed next.(二)Tell whether the following statements are true(T) or false(F) according to the passage A.(根据上文的内容判断下列句子的正误,共10分,每题2分)1. With the development of computer, the physical size of the CPU has often become bigger and bigger. ( F )2. The movement of electronic signals between main memory and the ALU as well as the control signal between the CPU and input /output devices are controlled by the control unit of the CPU. ( T )3. The CPU comprises the control unit and memory. ( F )4. The control unit performs all the arithmetic and logical (comparison) functions . ( F )5. The central processing unit (CPU) is the heart of the computer systems. ( T )Passage BA computer virus is a computer program that is created to make and spread copies of itself. The program may however also be designed to have other effects on the systems it infects, ranging from the annoying to the disastrous. Virus attacks are growing rapidly these days. According to BusinessWeek, the 76,404 attacks reported in the first half of 2003 nearly match previous year's total number . As new antivirus tools are more powerful than before, the virus writers are getting a lot smarter with newer and creative ways to attack network systems. Let's first examine some common virus types:Basic Virus - a piece of software code that is developed to attack computers and network systems via email or Internet connections. It quickly replicates itself and gradually attaches to files, programs or the hard drive.Trojan Horses - This is a program that doesn't replicate when entering a system but can be effectively used to open 'back doors.' Trojan Horses allow hackers to take control over a particular system or to steal very important data.Worm - this type of virus is able to spread itself automatically over the network from one computer to the next. During a worm attack, users' computers get infected without even having to click open email attachment or any program, etc.Since it is very difficult to avoid the virus, your best defense is a powerful antivirus program. In order to fight with such viruses, the software vendorsshould focus on making their products more robust. This may ask for a trade-off between user-friendliness and security. In specific cases it may require line-by-line inspection, code retooling and even systems automation to defend the installed programs.(三)choose the best answer according to the passage B.(根据上文的内容选择正确的答案,共10分,每题2分)1.A computer virus is a computer program that is created to make and spread C of itself.A.programs B.virus C. copies D.files2.Worm spread itself except by D .A.network B.E-mail C.program D.hardware 3.Antivirus program can scan and A virus.A.clean B.produce C.replicate D.make4.Trojan Horses C .A.quickly replicate itself and gradually attach to files, programs or the hard drive.B.infect the computer without even having to click open email attachment or any program.C.allow hackers to take control over a particular system or to steal very important data.D.avoid the virus to attack computer.5.According to Business Week, the B attacks reported in the first half of 2003 nearly match previous year's total number .A. 86,404 B. 76,404 C.56,354 D.34,876Passage CThe Internet, then known as ARPANET, was brought online in 1969, which initially connected four major computers at universities in the southwesternUS . The early Internet was used by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personal computers in those days, and anyone who used it, whether a computer professional or an engineer or scientist or librarian, had to learn to use a very complex system.The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP , and telnet were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standards by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources.In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network.Since the Internet was initially funded by the government, it was originally limited to research, education, and government uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.(四)Choose the best answer according to Passage C.(根据上文的内容选择正确的答案,共10分,每题2分)1. How many computers were connected to the initial Internet in 1969 ? BA. TenB. FourC. TwentyD. Three2. Only A could use the early Internet.A. computer experts, engineers, scientists, and librariansB. any experts, engineers, scientists, and librariansC. computer experts, engineers, scientists, and studentsD. experts, engineers, and scientists in universities in US3. The Internet became a lot easier for non-technical people to learn and use because of the common B .A. commandsB. protocolsC. topologiesD. architecture4. The first really friendly interface to the Internet appeared with theintroduction of a C system for files and information access.A. computerB. operatingC. menuD. application5. Which statement is not true according to Passage C? DA. Many more people in universities began to use the Internet in the 1970s, but it wasn't as user-friendly as today's standards.B. The restrictions to commercial uses changed as the independent commercial networks were not funded by the government.C. Commercial uses were allowed for the early Internet if they directly served the goals of research and education.D. The early Internet was logged in from home or office personal computers.Ⅲ.Translation(翻译,30分)(一) Translate the following sentences into Chinese.(将下列句子翻译成汉语,每题5分)1.

Do you always take a shopping bag with you when you go shopping, so that the shop doesn't waste plastic bags? If so, then you are a "Green", you are "environmentally conscious". That means that you are aware that human beings are using up the resources of the world too fast--and that to conserve the world's resources, we must "think green". Consumers all over the world are increasingly beginning to realise the need to buy "green products"-- products that are economically and harmlessly produced, and harmlessly disposed of after use. There are also campaigns to encourage people to recycle glass, paper, plastic and metal. As a result of such campaigns, fewer resources are being wasted.However, one thing is clear: without the cooperation of industry--big business--the world will not grow cleaner. For it is industry that turns raw materials into consumer products. Using modern technology, industry can create environmental disorder and confusion, wasting raw materials, and polluting the earth.There are signs that industry is becoming increasingly aware of its power to preserve, or destroy, the environment. Industry has for some time tried to use natural resources more economically. For example, power stations have becomemuch more efficient. As a result, they have become less wasteful in their use of resources.However, in recent years, industry has come to worry much more about controlling the amount of pollution during production. Responsible companies are trying to reduce the amount of air pollution. Apart from releasing harmful gases, other problems include the discharge of heavy metals into rivers and the sea, and the difficulty of finding enough space to dispose safely of the world's rubbish.Industry's task now is to find ways to reduce or eliminate forms of pollution. Increasingly the world will need products that, during their lifetime, do minimal damage to the planet, and that, at the end of their lives, can either be safely disposed of, or recycled to new uses. So, companies are now trying to ensure that rubbish is disposed of safely, or recycled where possible.Why should any company start this revolution? There are many pressures for change: customers' tastes change, as the consumer starts to "think green". Customers vote with their wallets and purses, as they question what products involve poisonous gases in their manufacture, and what products are biologically harmful during their use, and after their useful life comes to an end.More relevant perhaps in the long run, customers also have an influence on government: governments are now imposing stronger regulations on industry, and heavier penalties for polluting. Governments can make new laws about chemical discharges, tax the use of raw materials, and punish companies for polluting accidents. In short, society will and must demand cleaner and less wasteful industrial processes, cleaner products, and cleaner ways of disposing of these products, or recycling them.To develop these processes, and invent cleaner products, will call for whole new types of technology. The changes may well be enormous. What a fortune awaits the company that invents, say, a way of transporting people rapidly, safely and quietly, without discharging nasty gases, in a container that melts into the earth as soon as it reaches the end of its long life! The great engineering projects of the next century will not be the civil engineering of dams or bridges, but the bio-engineering of sewage works and garbage dumps.

Reading Comprehension ( Reading in depth)Section ADirections:In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.Most Americans would have a difficult time telling you, specifically, what the values are which Americans live by. They have never given the matter any thought.Over the years I have introduced thousands of international visitors to life in the United States. This has caused me to try to look at Americans through the eyes of foreign visitors. I am confident that the values listed in this booklet describemost (but not all ) Americans, and that understanding these values can help you, the international visitor, understand Americans.It is my belief that if foreign visitors really understand how deeply these 13 values are ingrained in Americans, they will then be able to understand 95% of American actions--actions which might otherwise appear “strange,”“confusing,” or “unbelievable” when evaluated from the perspective of the foreigner's own society and its values.The different behaviors of a people or a culture make sense only when seen through the basic beliefs, assumptions and values of that particular group. When you encounter an action, or hear a statement in the United States which surprises you, try to see it as an expression of one or more of the values listed in this booklet.47. Can an ordinary American tell you his/her value system? Why?_____________________________________________48. The author lists 13 values in his booklet to ___________.49. The word “ingrained” in Line 2, Paragraph 3 most probably means _________.50. Visitors sometimes find Americans behave in a strange, confusing orunbelievable way, probably because _____________.51. How can you understand a surprising behavior or statement of an Americanwhen you visit the United States?Section BDirections: There are 2 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 write the corresponding letter on the Answer Sheet.Passage OneQuestions 52 to 57 are based on the following passage.“No man is an island,” wrote the poet John Donne several centuries ago. He was acknowledging one of our most distinctive characteristics: the fact that we are social animals whose behavior and personalities are shaped by the groups to which we belong.Throughout life, most of our daily activities are performed in the company of others. Whether our purpose is working, playing, raising a family, learning, or simply relaxing, we usually pursue it in groups, even if the group is as small as twoor three people. Our need for human contacts is not merely a practical one; it is a deep psychological need as well. If people are deprived of the company of others for prolonged periods, mental breakdown is the usual result. Even the Geneva Convention (日内瓦公约),an international agreement that regulates the treatment of prisoners of war, recognizes this need. It regards solitary (孤独的) imprisonment for more than thirty days as a cruel form of torture (折磨).In its strictest sense, a group is a collection of people interacting together in an orderly way on the basis of shared expectations about one another's behavior. As result of this interaction, members feel a common sense of “belonging.” They distinguish members from nonmembers and expect certain kinds of behavior from outsiders.52. By “No man is an island,” John Donne means _____.A) no one can live on an island aloneB) a man is not surrounded by sea on all sidesC) a man and an island are irrelevantD) no one can live in isolation from other people53. The fact that we work or even play in groups illustrates the point that ____.A) people are different from animalsB) Donne recognized the group to which he belongedC) human beings are social animalsD) human behavior and personalities are formed by others54. “Breakdown” as used in Line 6, Paragraph 2 most probably means ____.A) separation B) collapse C) analysis D) function55. According to the passage, what is NOT a characteristic of group?A) There are at least two people in it.B) The members share some common grounds.C) The members work for one purpose.D) The members interact regularly with each other.56. This passage is mainly about _______.A) the importance of human contactsB) patterns of human behaviorC) the importance of human activitiesD) patterns of human societyPassage TwoQuestions 57 to 61 are based on the following passage.The word health can be used in a number of ways. In the past, health was only the absence of disease or illness. Today, though, health has a broader meaning.Health is the state of your well-being that includes how you feel physically, mentally, and socially. Wellness is another term that describes this broader view of health. You can understand the need for a broader definition if you think about how health in your life is different from health in your grandparents' lives.In 1900, the main causes of death were diseases that were spread by bacteria (细菌) and viruses (病毒). If you had lived then, the danger of your dying from pneumonia (肺炎) would have been three times greater than the danger of your dying from cancer.The diseases that were most common in 1900 affected people of all ages. It is not surprising that the emphasis of health was on freedom from illness around 1900. Today many of the diseases that were common in 1900 can be prevented or cured by improved medicines and methods of sanitation(卫生). Most diseases now are likely to occur later in life. You as a teenager will probably not have to think about the same threats to your health as your grandparents did.These improvements in health conditions mean that not only can you now enjoy a better life, but you also have a greater chance of having a longer life. Controlling diseases has increased the life expectancy in the United States. Generally, people born more recently have higher life expectancies. Since 1900, the life expectancy in the United States has increased by more than 27 years. It has increased from 47 years for those born in 1900 to 74 years 1981.57. According to Paragraph 1, health and wellness ______.A) can be used interchangeably on all occasionsB) are different in that the latter has a broader senseC) had the same meaning in the pastD) both refer to the state of your well-being58. Which of the following statements is true?A) Diseases caused by bacteria and viruses were incurable in 1900.B) Bacteria and viruses are the main causes of death today.C) Medicines for curing pneumonia were not available in 1900.D) Pneumonia caused as many deaths in 1900 as cancer does today.59. “Life expectancy” in the last paragraph most probably means ____.A) the kind of life that a person may expect to liveB) the mode of life that a group of people have livedC) the length of time that a person or an animal has livedD) the length of time that people may expect to live60. On an average, people in America who were born in 1900 ______.A) had a life-span of 74 yearsB) lived a shorter but better life than those born laterC) lived to 47 years of ageD) lived 27 years longer than those born in 198161. The intended readers of the passage are _______.A) teenagers B) the diseasedC) adults D) aged peoplePart V. Cloze ( 15 minutes) Directions: There are 20 blanks in the following passage.

四.Translate the following paragraph into English (30 points)
When purchasing a computer, the purchaser should “look under the hood” to ensure that the computer contains high-quality components. Low-quality components have a greater tendency to fail after a few years of operation. If a critical component fails, the computer may not be usable for several weeks while the component is replaced. If the failed component is obsolete and no longer available, the computer must usually be rebuilt using new components. If the hard drive fails, the contents of the hard drive may be lost. Although name-brand computers tend to contain high-quality parts, this is not always the case. The buyer must ultimately ensure that his computer contains high-quality components.。
