These parts are interconnected by buses, often made of groups of wires.Inside each of these parts are trillions of small electrical circuits which can be turned off or on by means of an electronic switch. Each circuit represents a bit (binary digit) of information so that when the circuit is on it represents a “1”, and when off it represents a “0” (in positive logic representation). The Circuits are arranged in logic gates so that one or more of the circuits may control the state of one or more of the other circuits.The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are collectively known as a central processing unit (CPU). Early CPUs were composed of many separate components but since the mid-1970s CUPs have typically been constructed on a single integrated circuit called a microprocessor.The control unit (often called a control system or central controller) manages the computer’s various components; it reads and interprets, (decodes) the program instructions, transforming them into a series of control signals which activate other parts of the computer. Control systems in advanced computers may change the order of some instructions so as to improve performance.

These activities may involve the development of software from scratch in a standard programming language like Java or C. Increasingly, however, new software is developed by extending and modifying existing systems and by configuring and integrating off-the-shelf software or system components.Software processes are complex and, like all intellectual and creative processes, rely on people making decisions and judgments. Because of the need for judgment andcreativity, attempts to automate software processes have met with limited success. Computer-aided software engineering (CASE) tools can support some process activities. However, there is no possibility, at least in the next few years, of more extensive automation where software takes over creative design from the engineers involved in the software process.Although there are many software processes, some fundamental activities are common to all software processes:1). Software specification The functionality of the software and constraints on its operation must be defined.2). Software design and implement-ation The software to meet the specification must be produced.3). Software validation The software must be validated to ensure that it does what the customer wants.4). Software evolution The software must evolve to meet changing customer Needs. Although there is no ‘ideal’ software process, there is scope for improving the software process in many organizations. Processes may include outdated techniques or may not take advantage of the best practice in industrial software engineering. Indeed, many organizations still do not take advantage of software engineering methods in their software development.(1)、A software process is _______.•product•standard programming language•existing system正确答案：B(2)、Software processes ___________.•complex and intellectual enough to be developed byComputer-aided software engineering (CASE) tools.•rely on Computer-aided software engineering(CASE) tools.•depend on the people making decisions and judg ments正确答案：A(3)、software processes usually include ________ activities.•••正确答案：C(4)、Improving the software process in many organizations is ______.•••正确答案：D(5)、Software design and implementat-ion means that _________.•functionality of the software and constraints on its o peration must be defined.•software must be validated to ensure that it does w hat the customer wants.•software must evolve to meet changing customer Ne eds.正确答案：B。

Comprehension（阅读理解，40分）( )（一）Fill in the blanks with suitable words or expressions from the list given below, and change the form where necessary. （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。
