Reading comprehension(阅读理解)(35%)(一) Fill in the blanks with suitable words or expressions from the list given below, and change the form where necessary (从下面所列词语中选择合适的词语, 以其适当的形式填空)(5%) high-level language assembly language writtenmachine language notationA programming language, designed to facilitate the communication between human and computers, is a _ for describing computation in readable form. There are 3 levels of programming languages, they are _, which can be run directly by computer; _and_. 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_ . Therefore, first thing to be decided about a task is to choose which programming language is best suited for the job.Passage AThe hardware of a digital computer system is divided into four functional sections. The block diagram of Fig.2-4 shows the four basic units of simplified computer: the input unit, central processing unit, memory unit, and output unit. Each section has a special function in terms of overall computer operation.Fig.2-4 A Digital Computer The central processing unit (CPU) is the heart of the computer system. It is responsible for performing all arithmetic operations and logic decisions initiated by the program. In addition to arithmetic and logic functions, the CPU controls overall system operation. There are two main sections found in the CPU of a typical personal computer system: the arithmetic-logic section and the control section. But these two sections are not unique to personal computer. They are found in CPUs of all sizes.Every processor comes with a unique set of operations such as ADD, STORE, or LOAD that represent the processors instruction set. Computer designers are fond of calling their computer machines, so the instruction set is sometimes referred to as machine instruction and the binary language in which they are written is called machine language.The memory unit of the computer is used to store information such as numbers, names, and addresses. By “store”, we mean that memory has the ability to hold this information for processing or for outputting for later time. The programs that define how the computer is to process data also reside in memory.In computer system, memory is divided into two different sections, known as main storage and auxiliary storage. They are also sometimes called internal memory and external memory respectively. External memory is used for long term storage of information that is not in use. For instance, it holds programs, files of data, and files of information. In most computers, this part of memory employs storage on magnetic media such as magnetic tapes, magnetic disks, and magnetic drums. This is because they have the ability to store large amount of data. Internal memory is a smaller segment of memory used to temporary storage of programs, data, and information. For instance, when a program is to be executed, its instructions are first brought from external memory into internal memory together with the files of data and information that it will affect. After this, the program is executed and its files updated while they are held in internal memory. When the processing defined by the program is completed, the updated files are returned to external memory. Here the program and files are retained for use at later time. (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. The four basic units of simplified computer: the input unit, central processing unit, memory unit, and output unit. ( )2. The CPU is responsible for performing some arithmetic operations and logic decisions. ( ) 3. “ADD AX, BX” is an instruction of machine language. ( )4. Main storage and auxiliary storage are sometimes called internal memory and external memory respectively. ( )5. The binary language which they are written in machine instruction is called machine language. ( ) Passage BIn 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 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. (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%)1If you want to solve the computational problem with a computer, you should learn how to_.A. calculate B. program C. add D. subtract2. Computer programming is the process of planning and creating a sequence of _ for a computer to follow. A. steps B. process C. lines D. graphics3. The term coder is used to describe _.A. machine B. computer C. keyboard D. person4. In order to solve a computational problem, you can let a person or a _to do it.A. machine B. computer C. keyboard D. 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.Passage CA 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 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 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 C(根据上文的内容选择正确的答案)(10%)1A computer virus is a computer program that is created to make and spread _of itself.A. programs B. virus C. copies D. files2Worm spread itself except by_. .A. network B. E-mail C. program D. hardware3Antivirus program can scan and_ virus. A. clean B. produce C. replicate D. make 4Trojan Horses_ .Aquickly replicate itself and gradually attach to files, programs or the hard drive.Binfect the computer without even having to click open email attachment or any program.Callow hackers to take control over a particular system or to steal very important data.Davoid the virus to attack computer.5According to Business Week, 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得分阅卷人.
