（二）．Translate the following paragraphs into Chinese.（将下列各段翻译成汉语）。1．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.

中央处理器（CPU）是计算机系统的心脏。一台计算机相对于其它计算机的速度是快还是慢，除了别的因素外，CPU的配置起着决定的作用。CPU是最复杂的计算机系统设备，它根据提供的指令负责指挥协调计算机系统的全部活动。当老一代计算机被新的一代计算机代替的时候，CPU的实际尺寸往往变得越来越小，而其速度和能力却增加了许多。这种变化的结果就使得微机缩小得可以放在你的桌子上或你的膝上。

2．Personal computer software is based on specific operating systems and machines. Operating systems software defines the ‘personality’ of the computer by specifying the way in which programs are controlled, files are stored and retrieved, and how the system’s hardware components are held together. Software written to run on a specific PC operating system can’t run on another. To use PCs effectively, one must understand the capabilities of their operating systems software.

个人计算机软件建立于特定的操作系统和计算机。操作系统软件通过一系列措施定义了计算机的性能，包括如何控制程序执行、文件如何存储和读取、系统硬件组件如何管理等。基于某一特定的PC操作系统编写的软件不能用于其他操作系统。为了充分利用PC机，用户必须了解操作系统的特性。

3．An application software (also called end-user program) is any program designed to perform a specific function directly for the user or, in some cases, for another application program. Examples of application software include word processors; database programs; Web browsers; development tools; drawing, paint, and image editing programs; and communication programs. Figuratively speaking, application software sits on top of system software because it is unable to run without the operating system and system software.

应用软件（又称作终端用户程序）是直接为用户设计的具有专门功能的软件，或在某些情况下，为另一种应用程序设计的。应用软件的例子有：字处理器，数据库程序，网络浏览器，打发工具，绘图和图像编辑程序，通信程序等。比喻的说，应用软件坐在系统软件的上面，这是因为如果没有操作系统和系统公用程序应用软件将不能运行。

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

They are more powerful and reliable and, importantly, are very economical in terms of energy consumption. Their presence opens a new era in the field of IT technologies and means that the cloud technology is getting closer. These processors are primarily designed for servers, data centers (DPC) and supercomputers. The emergence of this class of devices is not accidental. According to the regional director of Intel in Russia and other CIS states Dmitri Konash who spoke at the event, the market of IT-technology is developing so rapidly that, according to forecasts, by 2015 there will be 15 billion devices connected to the Internet, and over 3 billion of active users. 上周，英特尔公司向俄罗斯和其它独联体国家的公众推出了英特尔Xeon E5-2600系列处理器，它们更加强大可靠，尤其是在能量消耗方面更加经济实惠。它们的问世意味着IT技术领域开始了一个新时代，标志着云技术距离我们越来越近。这些处理器主要是为服务器、数字处理中心和超级计算机设计的。这种处理器的出现并非偶然。根据英特尔公司俄罗斯和其他独联体地区负责人Dmitri Konash就此事发表的看法，IT技术市场的发展速度极快，根据预测，到2015年与英特网连接的设施将有150亿，用户超过30亿。 [Ex 6] 1.

计算机专业英语作业： 1、请将视频“什么是电脑硬件”中所述内容用英文表示。 For most people, computers are becoming a part of real life, the film will help you konw how it works. Their interior looks very complicated, but if the decomposition of parts, you will see a simple side of computers , This is《computer hardware in Plaining English 》,you see them, they are coming all shapes and sizes,but its work in some ways. In fact, if you can see their internals of computers, You will find that they all have the basic parts,the haddwares,do large part of the works in the computers.to explan,let’s look at some things you know ,like a house.what a great thing in the house is you have full space to put all the iterms.in fact ,many houses have basements.The basement is a good place to store debris.Basement, the more you can store.The same principle applies to computers.We need not boxes and bicycles, but photos, music, documents and https://www.360docs.net/doc/751997305.html,plete this task in the computer hard drive rather than in the basement, a computer hard drive, holds all your files will be used later, like basements, like the larger hard drive, the more things you can store. Basement is not perfect, going to the basement to take the things you need to spend much time, maybe put a cupboard on the ground floor can help you solve this problem, you can quickly get the items you want, although the cabinet can not put too many items, at least you do not always go to the basement, in the computer too, The computer can not quickly access to the data stored in the hard disk, because the computer go a long way to gain access to the hard disk data. In the computer memory (RAM) is like a cupboard, RAM's full name is called [random access memory], which allows the computer to access data more quickly and, of course, it also means that the operation of RAM to make your computer faster , but this cupboard (RAM) has a drawback, the memory will be cleared of stored data When every time you restart, of course, to make the house a variety of household appliances can operate at the appropriate time, you must have an Explorer to help you manage these appliances, if the weather is too hot , you maybe need to open the air conditioner to adjust the temperature, when it is dark, you need to turn on the lights. Computers, too, must have a bit Explorer to ensure that all other parts are functioning properly, the Explorer is the processor (CPU), small size of the processor, like a computer exclusive (in charge), it will send and receive information and to assist the software to complete the work. The faster the processor, the faster execution speed of the computer would be, so, let us revisit. Hard drive, like a basement, it can store the information you need. Memory, like a cupboard, which can increase data access speed. Processor, like the Field Explorer, always able to complete the work that we deliver, but also to ensure the normal operation of the various parts. Next time, when you use the computer, think about plain English in the host computer's computer hardware what happened, the various parts of computer hardware complement each other, to help you do all the things I Common Craft's Lee LeFever, "Computer hardware of Plaining English "The film recorded by me, if you need a higher quality video, or need to use the authorization of the film, please contact me https://www.360docs.net/doc/751997305.html, website. 2、请将以下英文翻译为中文。
