"The central processing unit(CUP) 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 in micro-Computers that are small enough to fit on your desk and your lap. The CPU comprise 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 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) 1.With the development of computer, the physical size of the CPU has often become bigger and bigger.

"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 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.

"Microsoft Word, known as Word, is a very powerful Windows word-processing package. It is a member of Microsoft office. Word offers many features, including desktop publishinand access to the World Wide Web. Because Word is part of the Microsoft Office, documents created in Word can be easily incorporated into Excel, PowerPoint and Access files. Word has several editions: Fig.1 The interface of Word XP Word 97, Word 2000 and Word XP. Microsoft Word XP is the current Windows version of this word processor. The following figure is the introduction of Word XP. ?Title bar – displays the name of the current application and name of the current document ?Menu bar – lists the names of the menus available ?Standard toolbar – gives you quick access to frequently used editing functions. Names of buttons are displayed when the mouse rested over them. ?Scroll bars – used to move through a document – vertical and horizontal ?Ruler –enables you to change left and right margins and to set or remove tab stops. ?Text area –where you can edit your document. ?Status bar – displays current document information.

"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 (与……相比)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.
