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 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).
( ) requirements maintain
disciplined coding modify
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 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分，每题2分）

Passage C
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.
(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 .

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.

Doctors of that time knew very little about causes of sickness or ways of preventing it. Thousands of men in poor health became soldiers. Hundreds of others had never had childhood diseases. Many of these soldiers could not withstand the epidemics of measles, mumps, and whooping cough that went through the camps. Army life was hard. Soldiers got few fruits or vegetables. There was no milk unless they happened to find a cow. Neither their clothes nor their shelters protected the troops from rain, snow, and cold. Sickness and disease were spread by insects, rats, and impure drinking water. Often the men drank straight from muddy streams. Gunshot wounds were serious, as in any war,

Robot Competition From 11th to 13th October 2013, these three days are special for my teammates and me. I took part in the fifth Robot Competition of Anhui province. After continuous efforts, we got the third prize in the end. In April 2013, this competition was announced in our class by Mr He. In that moment, many students registered for the competition. After hardly training, there were only fifteen students remaining. We were divided into five teams. Each included three people. There were three teams taking part in wheel type robot competition (or named intelligent car). And the other two majored in dancing robot. My two roommates and I engaged in the designing of robot dance. We controlled the robots by program. But the program was programmed in BASIC, which is a high level programming language. The problem was that we had never touched to that language besides C or C++. So, we must learn the language before designing the action. It seemed difficult but we had never lost our courage. After seeking enough data from the Internet and the library, we spent about a few weeks to learn it. When we felt the fundamental grammar was easy, we began to design the dancing action. That was the most important and most difficult part. We spent much time on
第一单元：计算机与计算机科学 课文A：计算机概览 一、引言 计算机是一种电子设备，它能接收一套指令或一个程序，然后通过对数字数据进行运算 或对其他形式的信息进行处理来执行该程序。 要不是由于计算机的发展，现代的高科技世界是不可能产生的。不同类型和大小的计算 机在整个社会被用于存储和处理各种数据，从保密政府文件、银行交易到私人家庭账目。计 算机通过自动化技术开辟了制造业的新纪元，而且它们也增强了现代通信系统的性能。在几 乎每一个研究和应用技术领域，从构建宇宙模型到产生明天的气象报告，计算机都是必要的 工具，并且它们的应用本身就开辟了人们推测的新领域。数据库服务和计算机网络使各种各 样的信息源可供使用。同样的先进技术也使侵犯个人隐私和商业秘密成为可能。计算机犯罪 已经成为作为现代技术代价组成部分的许多风险之一。 二、历史 第一台加法机是法国科学家、数学家和哲学家布莱斯.帕斯卡于1642年设计的，它是数 字计算机的先驱。这个装置使用了一系列带有10个齿的轮子，每个齿代表从0到9的一个数字。轮子互相连接，从而通过按照正确的齿数向前转动轮子，就可以将数字彼此相加。17世纪70 年代，德国哲学家和数学家戈特弗里德.威廉.莱布尼兹对这台机器进行了改良，设计了一台 也能做乘法的机器。 法国发明家约瑟夫―玛丽.雅卡尔，在设计自动织机时，使用了穿孔的薄木板来控制复 杂图案的编织。在19世纪80年代期间，美国统计学家赫尔曼.何勒里斯，想出了使用类似雅 卡尔的木板那样的穿孔卡片来处理数据的主意。通过使用一种将穿孔卡片从电触点上移过的 系统，他得以为1890年的美国人口普查汇编统计信息。 1、分析机 也是在19世纪，英国数学家和发明家查尔斯.巴比奇，提出了现代数字计算机的原理。 他构想出旨在处理复杂数学题的若干机器，如差分机。许多历史学家认为，巴比奇及其合伙 人，数学家奥古斯塔.埃达.拜伦，是现代数字计算机的真正先驱。巴比奇的设计之一，分析 机，具有现代计算机的许多特征。它有一个以一叠穿孔卡片的形式存在的输入流、一个保存 数据的“仓库”、一个进行算术运算的“工厂”和一个产生永久性纪录的打印机。巴比奇未 能将这个想法付诸实践，尽管在那个时代它在技术上很可能是可行的。 2、早期的计算机 模拟计算机是19世纪末开始制造的。早期型号是靠转动的轴和齿轮来进行计算的。用任 何其他方法都难以计算的方程近似数值，可以用这样的机器来求得。开尔文勋爵制造了一台 机械潮汐预报器，这实际上就是一台专用模拟计算机。第一次和第二次世界大战期间，机械 模拟计算系统，以及后来的电动模拟计算系统，在潜艇上被用作鱼雷航线预测器，在飞机上 被用作轰炸瞄准具的控制器。有人还设计了另一个系统，用于预测密西西比河流域春天的洪 水。 3、电子计算机 第二次世界大战期间，以伦敦北面的布莱切利公园为工作地点的一组科学家和数学家， 制造了最早的全电子数字计算机之一：“巨人”。到1943年12月，这个包含了1500个真空管 的“巨人”开始运转了。它被以艾伦.图灵为首的小组用于破译德国用恩尼格码加密的无线 电报，他们的尝试大部分是成功的。 除此而外，在美国，约翰.阿塔纳索夫和克利福德.贝里早在1939年就在艾奥瓦州立学院
