Software Engineering, which means the application of engineering to software, is a method to develop, operate and ________ software. 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 syste
m 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）（10分,每题2分）
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 (comparison) functions ( ) 5. The central processing unit (CPU) is the heart of the computer systems. ( ) Passage B
In 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 of program 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 s
pecifications 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.
(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分，每题2分）

A. calculate B. program C. add D. subtract

A 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 effecti
vely 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.
(四)、choose the best answer according to the passage B.(根据上文的内容选择正确的答案。10分，每题2分)
1.A computer virus is a computer program that is created to make and spread of itself. A．programs B．virus C． copies D．files 2．Worm spread itself except by .

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 BusinessWeek, the 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．34,876 Ⅲ.Translation.翻译(30分)
(一) Translate the following sentences into Chinese.（将下列句子翻译成汉语。）（共20分，每题5分）
1. For developing a software product, the development process is divided into 5 stages: Requirements Analysis & Specification, Design, Coding, Testing, and Maintenance.
2. Functional testing tests whether the output is the expected result with the valid input.
3. EDI refers to the electronic exchange of business information between two companies using a specific and structured format over private networks.
4．Some applications, such as Word, allow for several windows in a special mode called MDI in which you can open multiple documents within the same application.
(二) Translate the following paragraph into Chinese.（将下段文章翻译成汉语。）（共10分）
A high-level language is an artificial language with which we can write various instructions. This is possible not because computer processors are now so technologically advanced that they can ?understand
? these languages. You should translate from programming languages into machine language which can be understood by the computer processors. Compilers can accomplish this task. This does mean that a high-level language program is not directly executable: it must be compiled to produce processor program, which is executable.
