Fill in each of the blanks with one of the words given in the following list, making changes if necessary:Early computer networks used leased telephone company lines for their connections. Telephone company systems of that time established a single connection between sender andreceiver for each telephone call, and that connection carried all data along a single path. Whena company wanted to connect computers it owned at two different locations, the company placed a telephone call to establish the connection, and then connected one computer toeachend of that single connection.The U. S. Defense Department was concerned about the inherent risk of thissingle-channel method for connecting computers, and its researchers developed a differentmethod of sending information through multiple channels. In this method, files and messagesare broken into packets that are labeled electronically with codes for their origins, sequences,and destinations. In 1969, Defense Department researchers in the Advanced Research ProjectsAgency (ARPA) used this network model to connect four computers into a network called theARPANET. The ARPANET was the earliest of the networks that eventually combined to become what we now call the Internet. Throughout the 1970s and 1980s, many researchers inthe academic community connected to the ARPANET and contributed to the technological developments that increased its speed and efficiency.IV. Translate the following passage from English into Chinese:因特网只是提供了将许许多多的计算机连接在一起的物理与逻辑基础结构。

That is, the development of software is on a systematic, _________, quantitive basis. Before starting the development of software, you have to systematically approach the problem. You have to understand the _________ (what the software is supposed to do), carry out the design, do the _________, carry out a rigorous testing and if the software is as per the requirements, release the software to the customer. Subsequently, if the customer wants some changes--refinements or enhancements then the software has to be _________. Passage A The 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, which its speed and capacity have increased tremendously. Indeed, these changes have resulted inmicro-Computers that are small enough to fit on your desk and 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 signalsbetween 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 comparison. 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)(10%)1. With the development of computer, the physical size of the CPU has often become bigger and bigger. ( )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. ( )3. The CPU comprises the control unit and memory. ( )4. The control unit performs all the arithmetic and logical functions. ( )5. The central processing unit (CPU) is the heart of the computer systems. ( ) 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 Business Week, 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 systembut 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 vendors should 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)(10%)1．A computer virus is a computer program that is created to make and spread _________of itself.A. programsB. virusC. copiesD. files 2．Worm spread itself except by_________. .A. networkB. E-mailC. programD. hardware 3．Antivirus program can scan and_________ virus.A. cleanB. produceC. replicateD. make 4．Trojan Horses_________ .A．quickly replicate itself and gradually attach to files, programs or the harddrive. 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_________ attacks reported in the first half of 2003 nearly match previous year's total number .A. 86,404B. 76,404C. 56,354D. 34,876 Passage CIn order to solve a computational problem, its solution must be specified in terms of a sequence of computational steps, each of which may be performed by a human or a digital computer. If you want to solve the computational problem with a computer, you should learn how to program. The task of developing programs for the solution of computational problems is referred to as programming. Computer programming is the process of planning and creating a sequence of steps for a computer to follow. In general, this process will help us resolve a problem, which is either too tedious or difficult to work out otherwise. So programming is breaking a task down into small steps.Programming is sometimes contrasted with coding. Coding generally refers to the writing of programs for given program specification, while programming includes the task of preparing the program specification as well as that of writing the program. The text of a program is sometimes referred to as code, and lines ofprogram text are referred to as lines of code, especially in the case of machine-language programs. The term coder is used to describe a person engaged exclusively in implementing program specifications prepared by others.What's actually involved in programming - the actual process of writing programs?Here's a quick overview of the process:· Write a program.· Compile the program.· Run the program.· Debug the program.· Repeat the whole process until the program is finished.(四) Choose the best answer according to the passage C(根据上文的内容选择正确的答案)(10%)1．If you want to solve the computational problem with a computer, you should learn how to_________.A. calculateB. programC. addD. subtract 2. Computer programming is the process of planning and creating a sequence of _________ for a computer to follow.A. stepsB. processC. linesD. graphics3. The term coder is used to describe _________.A. machineB. computerC. keyboardD. person4. In order to solve a computational problem, you can let a person or a _________to do it.A. machineB. computerC. keyboardD. mouse5. Which of the following is not the stage of programming? _________.A. Write a program.B. Debug the program.C. Print the program.D. Compile the program.(一) Translate the following sentences into Chinese.（将下列句子翻译成汉语） (12%)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.2．An application software is any program designed to perform a specific function directly for the user or, in some cases, for another application program.3．A small network may only connect two computers inside a home to share a single printer and Internet connection4．There is free firewall software available that can run on your computer and provide a good level of protection to your network.(二) Translate the following paragraph into Chinese.（将下段文章翻译成汉语）（8%）Input Devices. Computer systems use many devices for input purpose. Some Input Devices allow direct human/machine communication, while some first require data to be recorded on an input medium such as magnetic material. Devices that read data magnetically recorded on specially coated plastic tapes or flexible or floppy plastic disks are popular. The keyboard of a workstation connected directly to or online to a computer is an example of a direct input device. Additional direct input devices include the mouse, input pen, touch screen, and microphone.Regardless of the type of device used, all are components for interpretation and communication between people and computer systems.命题教师游彦教研室主任签字【第页共页】湖北职业技术学院2008-2009学年度第一学期期末考核试卷参考答案及评分标准考核课程：计算机英语考试类型：理论考试方式：闭卷笔试学生所在院系：信息技术学院年级： 2007 试卷： B执笔人：要求：明确标注每小题或每步骤得分点要求：明确标注每小题或每步骤得分点Ⅰ.
