(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. SQL Server is designed to allow thousands of users to access the database at the same time and is a true client/server database system.1. SQL服务器用于允许成前上万的用户同时访问数据库,是一个真正的客户端/服务器端的数据库系统。

And they’ll contain up to one billion transistors.Over the next few years the PC will remain the main computing tool for most people, but it will be joined by all kinds of now, microprocessor – powered devices that will make your life even easier. For example, when you’re traveling you‘ll be able to call up your itinerary, send an E-mail postcard, book an appointment with your doctor or balance your bank account using a handheld PC that will know what information you need, and when and where you need it. And you’ll be able to get a map, hotel guide or the news from the Web via new kinds of cell phones.。

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.。
