The Internet, then known as ARPANET, wasbrought online in 1969, which initiallyconnected four major computers at universitiesin the southwestern US . The early Internet wasused by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personalcomputers in those days, and anyone who used it, whether a computer professional or an engineeror 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。

Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the1500 students at the college will receive a laptop. The laptops are part of a＄10 million computer program at Westlake, a 110-year-old college. Thestudents with laptops will also have access to the Internet. In addition, theywill be able to use e-mail to “speak” with their teachers, their classmates,and their families. However, the most important part of the laptop program isthat students will be able to use computers without going to computer labs.They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops becomemore powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but alsolibraries and other resources. State higher-education officials are studyinghow laptops can help students. State officials are also testing laptopprograms at other universities, too. At Westlake College, more than 60 percentof the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”笔记本电脑在世界各地流行。

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 ComputerThe 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 processor’s 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 isexecuted 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%)1．If you want to solve the computational problem with a computer, you should learn how to_________.A. calculateB. programC. addD. subtract2. 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.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 asystem 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%)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 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_________ attacks reported in the first half of 2003 nearly match previous year's total number .A. 86,404B. 76,404C. 56,354D. 34,876(一)T ranslate the following sentences into Chinese（将下列句子翻译成汉语）(12%)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)T ranslate 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. SomeInput 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：A执笔人：要求：明确标注每小题或每步骤得分点Ⅰ.

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.1．If you want to solve the computational problem with a computer, you should learn how to .A. calculateB. programC. addD. subtract2. Computer programming is the process of planning and creating a sequence of for a computer to follow.A. stepsB. processC. linesD. graphics3.

Debug the program.C. Print the program.D. Compile the program.五、Translate the following sentences into Chinese.（本大题共6小题，每小题5分，共30分)1. The program, which tells the computers what to do and the data, which provide the information needed to solve the problem, are kept inside the computer in a place called memory.2. In a big mainframe computer the processor is called a Central Processing Unit, or CPU, while in a microcomputer, it is usually known as a microprocessor.3. The memory unit is an essential component in any digit computer since it is needed for storing the programs that are executed by the CPU.4. At the beginning of each instruction cycle, the CPU fetches an instruction from memory.5. It is very easy to set up a memory system that consists of a single chip.6. If we are going to say that a given program thinks like a human, we must have some way of determining how humans think.六、Translate the following paragraph into Chinese.（20分)Definitions of artificial intelligence vary along two main dimensions. One is concerned with thought processes and reasoning, the other addresses behavior. Also, some definitions measure success in terms of human performance, whereas the others measure against an ideal concept of intelligence, which we will call rationality. A system is rational if it does the right thing. All this gives us four possible goals pursue in artificial intelligence: system that like humans, systems that think rationally, system that act like humans and systems that act rationally.。

Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. In parallelcomputing parts of a problem are worked on simultaneously by different processors, and this speed up the solution of the problem. Another type of parallel computing called distributed computing use CPUs from many interconnected computers to solve problems. Research into artificial intelligence (AI) has led to several other new styles of programming.2.High-level languages are commonly classified asprocedure-oriented, functional, objected-oriented, logic languages. The most common high-level languages today are procedure-oriented languages. In these languages, one or more related blocks of statements that perform some complete function are grouped together into a program module, or procedure, and given a name such as “procedure A”. If the same sequence of operations is needed elsewhere in the program, a simple statement can be used to refer back to the procedure. In essence, a procedure is just a mini-program. A large program can be constructed by grouping together procedures that perform different tasks.四、汉译英题（20分）最著名的互联网例子是因特网。

(Total 40 points, ten points each one)4.1Computer hardware can be divided into four categories: (1) input hardware, (2) storagehardware, (3) processing hardware, and (4) output hardware.(1) Input Hardware -- The purpose of input hardware is to collect data and convert it into aform suitable for computer processing. The most common input device is a keyboard. Itlooks very much like a typewriter keyboard. Its keys are arranged in the typicaltypewriter layout. There are also a number of additional keys. They can be used to enterspecial computer-related codes. Although it isn't the only type of input device available,the computer keyboard is the one, which is most generally used by the businesscommunity.(2) Storage Hardware -- The purpose of storage hardware is to provide a means of storingcomputer instructions and data in a form that is relatively permanent, that is, the data isnot lost when the power is turned off -- and easy to retrieve when needed for processing.Storage hardware serves the same basic function, as do office-filing systems except thatit stores data as electromagnetic signals or laser-etched spots, commonly on disk or tape, rather than on paper.(3) Processing Hardware -- The purpose of processing hardware is to retrieve, interpret, anddirect the execution of software instructions, which are provided to the computer. The most common components of processing hardware are the central processing unit and main memory.The central processing unit (CPU) is the brain of the computer. It reads and interprets software instructions and coordinates the processing activities that must take place. The design of the CPU affects the processing power and the speed of the computer, as well as the amount of main memory it can use effectively. With a well-designed CPU in your computer, you can perform highly sophisticated tasks in a very short time.Main memory (also called internal memory, primary storage, or just memory) can be thought of as an electronic desktop. The more desktop surface you have in front of you, the more you can place on it. Similarly, if your computer has a lot of memory, you can place more software instructions in it. The amount of memory available determines whether you can run single or sophisticated software; a computer with a large memory is more capable of holding the thousands instructions that are contained in more sophisticated software programs. A large memory also allows you to work with and manipulate great amounts of data and information at one time. Quite simple, the more main memory you have in your computer, the more you can accomplish.(4) Output Hardware -- The purpose of output hardware is to provide the user with themeans to view information produced by the computer system. Information is output in either hardcopy or softcopy form. Hardcopy output can be held in your hand - examples are paper with text (words or numbers) or graphics printed on it. Softcopy output is displayed on a monitor, a television- like screen on which you can read text and graphics.计算机硬件可被分为四种：输入硬件、存储硬件、处理硬件和输出硬件。
