计算机英语(第4版)课文翻译与课后答案
第一部分《计算机英语》参考译文第一单元：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。

Unit Four/Section BI. Fill in the blanks with the information given in the text:1. Information engineering emphasizes a modeling tool called entityrelationship diagrams.2. One of the disadvantages of model-driven development is the long durationof projects.3. Unlike structured analysis and design and information engineering,object-oriented analysis and design attempt to emerge the data and process concerns into singular constructs called objects.4. Unlike logical models, physical models show not only what a system is ordoes , but also how the system is physically and technically implemented.II.

Fill in the blanks with the information given in the text:1. New software may be developed from scratch or through the use of existingsystems and off-the-shelf software or system components.2. The three generic process models discussed in the text are often complementaryrather than mutually exclusive, especially for large system development.3. The waterfall model is so named because of the cascade from one phase to anotherin the software development process.4. The fundamental development activities of the waterfall model arerequirements analysis and definition, system and software design, implementation and unit testing, integration and system testing, and operation and maintenance.5. The two fundamental types of evolutionary development are exploratorydevelopment and throwaway prototyping.6. The evolutionary approach is often more effective than the waterfall approachin producing systems that meet the immediate needs of customers, but it is difficult to establish a(n) stable system architecture using this approach.7. CBSE is a(n) reuse-oriented approach to software development, which relieson a large base of reusable software components and an integrating framework for these components.8. While CBSE can reduce the amount of software to be developed and the associatedcost and risks, it cannot avoid requirements compromises which may lead to a system that does not meet the real needs of users.II.

Translate the following passage from English into Chinese:Software processes are complex and, like all intellectual and creative processes, rely on people making decisions and judgments. Because of the need for judgment and creativity, attempts to automate software processes have met with limited success. Computer-aided software engineering (CASE) tools can support some process activities. However, there is no possibility, at least in the next few years, of more extensive automation where software takes over creative design from the engineers involved in the software process.One reason the effectiveness of CASE tools is limited is because of the immense diversity of software processes. There is no ideal process, and many organization have developed their own approach to software development.Processes have evolved to exploit the capabilities of the people in an organization and the specific characteristics of the systems that are being developed. For some systems, a very structured development process is required while for others a flexible, agile process is likely to be more effective.软件过程比较复杂.而且像所有其他的智能和创造性过程一样.依靠人们作出决定和判断。

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。

Available in a variety of sizes, even the smallest's touchscreens are much larger than those of a smart phone or personal digital assistant. A tablet computer may be connected to a keyboard with a wireless link or a USB port. Convertible notebook computers have an integrated keyboard that can be hidden by a swivel joint or slide joint, exposing only the screen for touch operation. Hybrids have a detachable keyboard so that the touch screen can be used as a stand-alone tablet. Booklets include dual-touchscreens, and can be used as a notebook by displaying a virtual keyboard in one of them.Notes:cursor [ˈkə:sə] n. 光标swivel [ˈswivəl] n. 旋轴；旋转接头detachable [diˈtætʃəbl] adj. 可拆开的stand-alone adj. 独立运行的hybrids= hybrid computer混合计算机booklet [ˈbuklit]n. 笔记本式平板电脑平板电脑，也叫平板，是个人计算机的一款，可移动，是一个整体。
平板电脑主要依靠触屏操作（用户的手指发挥了鼠标和光标的作用，替代了台式和膝上电脑必须的物理硬件[即鼠标和键盘]。
还有一个与显示器整合的可隐藏的屏幕虚拟键盘）。
平板电脑型号多种，即使是最小的触屏也比智能手机或个人数字助理的屏幕大多了。
可以用无线连接或USB插口给平板电脑连接一个键盘。
可旋转笔记本电脑可以通过一个旋转铰链或一个滑动铰链把集成的键盘隐藏起来，仅仅在需要触摸时显示。
混合型计算机配有一个可拆分的键盘，这样触屏可以当作一个单独的平板电脑使用。
笔记本平板电脑包括两个触屏，在其中一个触屏上显示虚拟键盘就可以作为笔记本使用。

This has led to the introduction of bus systems designed specifically to support multiple peripherals. Common examples are the SATA ports in modern computers, which allow a number of hard drives to be connected without the need for a card. However, these high-performance systems are generally too expensive to implement in low-end devices, like a mouse. This has led to the parallel development of a number of low-performance bus systems for these solutions, the most common example being Universal Serial Bus. All such examples may be referred to as peripheral buses, although this terminology is not universal.Notes:1. Serial ATA (SATA) is a computer bus interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives.2. Universal Serial Bus USB支持多种外接设备的总线系统随着外接设备数量的不断增加，想用扩展卡来应付每一种外围设备越来越不现实了，这就产生了设计专门支持多种外接设备的总线系统。
