计算机英语》刘艺_王春生_第三版第3单元
第三单元：计算机语言与编程课文A：编程语言一、引言在计算机科学中，编程语言是用于编写可由计算机运行的一系列指令（计算机程序）的人工语言。
与英语等自然语言相类似，编程语言有词汇、语法和句法。
然而，自然语言不适合为计算机编程，因为它们会引起歧义，也就是说它们的词汇和语法结构可能被用多种方式进行解释。
用于计算机编程的语言必须有简单的逻辑结构，它们的语法、拼写和标点符号规则必须精确。
编程语言在复杂性和通用程度上差异很大。
一些编程语言是为了处理特定类型的计算问题或为了用于特定型号的计算机系统而编写的。
例如，FORTRAN和COBOL等编程语言是为解决某些普遍的编程问题类型而编写的——FORTRAN是为了科学领域的应用，而COBOL是为了商业领域的应用。
尽管这些语言旨在处理特定类型的计算机问题，但它们具有很高的可移植性，也就是说它?103f强梢杂美次 嘀掷嘈偷募扑慊 喑獭Ｆ渌 挠镅裕 缁 饔镅裕 俏?一种特定型号的计算机系统，甚至是一台特定的计算机，在某些研究领域使用而编写的。
最常用的编程语言具有很高的可移植性，可以用于有效地解决不同类型的计算问题。
像C、PASCAL和BASIC这样的语言就属于这一范畴。
二、语言类型编程语言可分为低级语言和高级语言。
低级编程语言或机器语言，是编程语言中最基础的类型，可以被计算机直接理解。
机器语言视计算机制造商与型号不同而有所区别。
高级语言是必须首先翻译成机器语言计算机才能理解和处理的编程语言。
C、C++、PASCAL和FORTRAN都是高级语言的例子。
汇编语言是中级语言，非常接近于机器语言，没有其他高级语言所表现出的语言复杂程度，但仍然得翻译成机器语言。
1、机器语言在机器语言中，指令被写成计算机能够直接理解的1和0（称作位）序列。
一条机器语言指令一般告诉计算机4件事：（1）到计算机主存（随机存储器）的什么位置去找一两个数字或简单的数据片；（2）要执行的简单操作，如将两个数字相加；（3）在主存的什么位置存放该简单操作的结果；（4）到什么位置去找下一条要执行的指令。

6/47
Programming Languhough these languages were designed to address specific categories of computer problems, they are highly portable, meaning that they may be used to program many types of computers.
尽管所有的可执行程序最终都是以机器语言的形式被计算 机读入的，但它们并非都是用机器语言编写的. 直接用机器语言编程极端困难，因为指令是0和1的序列.

（1）到计算机主存（随机存储器）的什么位置去找一两个数字 或简单的数据片；（2）要执行的简单操作，如将两个数字相 加；（3）在主存的什么位置存放该简单操作的结果；（4）到 什么位置去找下一条要执行的指令

Programming Language－Language Types
While all executable programs are eventually read by the computer in machine language, they are not all programmed in machine language. It is extremely difficult to program directly in machine language because the instructions are sequences of 1s and 0s.

Zhang Ning: Well, there might many causes for system crash. One of them is software. The simplest operation like installing and uninstalling might cause a crash in system. Problems within the system may also do that, so you have to be very careful when deleting DLL files, modifying Windows registry, or upgrading the operating system. Another cause is the hardware problem. Have you tried backing up the files? It would be a great help in system restoration when the problem doesn’t lie in the hardware. Cheng Hong: The service personnel installed a ghost program for me when I bought the computer. Will I lose the data in my hard disk if it is restored? Qian Liang: Not except the data on C: drive, where files on your desktop or in My Documents are stored. You may move them into other locations with a bootable disk or under DOS if there are any. Cheng Hong: There are a lot of learning materials in My Documents and on the desktop. Would you please help me transfer them? It might save me the trouble of calling for customer services, and what’s more important, I’d learn a lot from you. Qian Liang: No problem.
计算机英语(第3版)课文翻译和课后答案
《计算机英语（第3版）》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。

Unit3computers知识点
Unit3computers知识点Unit3 Computers 知识点在我们的日常生活和工作中，计算机（Computers）已经成为了不可或缺的一部分。
接下来，让我们一起深入了解一下关于计算机的一些重要知识点。
一、计算机的发展历程计算机的发展可以追溯到上世纪中叶。
早期的计算机体积庞大、运算速度慢，且功能有限。
例如，第一代计算机使用真空管作为主要组件，它们不仅体积巨大，而且耗能高、发热量大。
随着技术的进步，晶体管取代了真空管，使得计算机变得更小、更可靠、运算速度更快，这便是第二代计算机。
第三代计算机采用了集成电路，进一步减小了计算机的体积，提高了性能。
而到了第四代，超大规模集成电路的出现使得计算机能够走进千家万户，成为人们工作和生活的得力助手。
如今，计算机技术仍在不断发展，朝着更小的体积、更强的性能和更智能化的方向迈进。
二、计算机的组成部分计算机主要由硬件（Hardware）和软件（Software）两大部分组成。
硬件方面，包括中央处理器（CPU），它是计算机的“大脑”，负责执行各种计算和控制任务；内存（Memory），用于暂时存储正在运行的程序和数据；硬盘（Hard Disk），用于长期存储大量的数据和程序；显示器（Monitor），用于显示图像和信息；键盘（Keyboard）和鼠标（Mouse），作为输入设备，用于向计算机输入指令和数据；还有主板（Motherboard）、电源（Power Supply）等其他组件。
软件则分为系统软件（System Software）和应用软件（Application Software）。
系统软件如操作系统（Operating System），如Windows、Mac OS 和 Linux 等，负责管理计算机的硬件资源和提供基本的服务。
应用软件则是为了满足用户特定需求而开发的，如办公软件（Word、Excel 等）、图像处理软件（Photoshop 等）、游戏软件等。

Windows XP Operating System
What is an operating system(OS)? An OS consists of one or more programs that manage the operations of a computer. It controls the operations of the computer equipment, manages resources, provides a user interface, and runs application program. Basically, it performs a number of support functions. Before the program can be executed, it must first be copied into main memory, because the program that controls a computer must be in the main memory. The process of copying a program from disk to memory involves considerable logic. The source of a computer’s logic is software. Thus, if the application program is to be loaded, there must be a program in memory to control the loading process. That program is the operating system. It acts as an interpreter between the different application software programs and your computer. For example, the operating system recognizes input from an input device such as the keyboard, mouse, or microphone; coordinates the display of output on the monitor; instructs a printer how to print information; and manages data, instructions, and information stored on disk .A computer cannot function without an operating system. 大连理工大学出版社 OS (Operating System) abbr. 操作系统 interface n. 界面 execute v. 执行 considerable adj. 相当大的
