第7单元计算机网络和因特网第一部分听力和对话对话:搭建无线网络(目前,在Sophie的家里,她已将计算机直接连接到7调制解调器。
现在她想要用无线网络替换现有的有线网络,并且请求Henry和Mark帮忙。
)Henry:放松点,Sophie。
我保证安装比你想象的要容易得多。
简而言之只有4步。
Sophie: 真的吗?那该怎么做呢?Mark: 第一步是确保你拥有所需要的设备。
它们通常包括宽带互联网连接、一个无线路由器和一台带有内置的无线网络支持或一个无线网络适配器的计算机。
Sophie: 让我想想。
嗯,我认为它们现在齐全了。
那接下来怎么办?Mark: 下一个步是连接无线路由器。
关闭调制解调器之后,从计算机的背面拔掉网线,并且将它连入路由器背面的标有互联网、广域网或无线局域网的端口。
同时,网线的另一端应该连接到调制解调器。
Sophie: 那么,我怎么可以知道它们已经正确连上了?Henry: 那很容易。
要检查的话,接通并且启动调制解调器。
等待几分钟让它连接到互联网,然后接通并且启动无线路由器。
在一分钟之后,无线路由器中的互联网、广域网或无线局域网的灯是亮的,表明它已顺利地连接到了调制解调器。
Sophie: 嗯,还有其他的吗?Henry:接着,配置无线路由器。
你应该临时将计算机连接到无线路由器上没有被标为互联网、广域网或无线局域网的其中的一个开放网络端口。
然后,打开IE并输入地址和密码来配置路由器。
Sophie: 我怎样获得地址和密码?Henry: 可以在路由器附带的说明书上找到。
Mark: Sophie,在配置过程中你要特别注意三件事:无线网络的名称也就是服务区标识符、无线加密或者Wi-Fi保护访问,以及能够控制无线网络的管理密码。
顺便说一句,在配置完成之后,从计算机上拔掉网线。
[3]Sophie: 好的,我了解了。
Henry: 现在,我们进入最后一步,连接计算机。
Windows 7应该显示一个包含有可用的无线网络列表的无线网络图标。

Requirements:
1. The origins of the programming languages 2. The concepts of computer compilers 3. Main properties of object-orientation 4. 掌握复杂定语从句的翻译技巧
Abbreviations:
OOPL (object-oriented programming language) 面向对 象的程序设计语言
7.1 Introduction to Programming Language
A programming language represents a special vocabulary and a set of grammatical rules for instructing a computer to perform specific tasks. Broadly speaking, it consists of a set of statements or expressions understandable to both people and computers.
近来出现的新的程序设计语言,像C++,微软的Visual C++, Visual Foxpro,和Visual Java,他们都支持面向对象的程 序设计(OOP)技术。OOP这种程序设计要求编程人员不 仅要给出数据结构中的数据类型的定义,还需要给出作用 在这些数据结构之上的操作(函数,或方法)的类型。
程序设计语言是指令计算机实现某些具体任务的一套特殊词汇和一组语法 规则。从广义的角度说,它包括一组既能被人所理解又能被计算机所识别 的声明和表达式。

According to the mode of processing, computers are either analog or digital. They can be classified as mainframes, minicomputers, workstations, or microcomputers. All else (for example, the age of the machine) being equal, this categorization provides some indication of the computer’s speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historicsignificance, such as UNIVAC, introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.IV.Translate the following passage from English into Chinese.A computer system includes a computer, peripheral(外围的)devices, and software. The electric, electronic, and mechanical devices used for processing data are referred to as hardware. In addition to the computer itself, the term “hardware”refers to components called peripheral devices that expand the computer’s input, output, and storage capabilities. Computer hardware in and of itself does not provide a particularly useful mind tool. To be useful, acomputer requires a set of instructions, called software or a computer program, which tells the computer how to perform a particular task. Computers become even more effective when connected to other computers in a network so users can share information.计算机系统包括计算机、外围设备和软件。

第4单元操作系统第一部分听力和对话对话:关于操作系统的讨论(Henry想要了解更多有关于操作系统的内容,所以他在课后向Mark和Sophie请教)Henry: 一个操作系统可以实现的确切的功能是什么?Sophie: 它控制包括视觉体验、键盘、鼠标、麦克风以及触摸屏等搜集用户需求的用户接口的关键因素。
Mark:并且在幕后,操作系统忙碌地监控发生在设备内的操作。
Henry: 我了解诸如Wind ows、iOS等很基础的操作系统,但是我认为还有其他的操作系统有很广泛的用途。
Sophie:你说的很对。
操作系统可以根据它们在什么设备上使用来进行分类。
Mark:台式机操作系统是为台式机或者手提电脑而设计。
你在学校、在家或在工作中使用的电脑大部分都配置有台式机操作系统,如Microsoft Wind ows,OS X,或者Chrome OS。
Sophie:另外,像iOS和Android这样的操作系统被定义为移动操作系统,因为它们被设计用于手机、平板电脑、电子书阅读器。
Henry:还有其他的吗?Sophie:当然。
被部署用于网络、文件、应用、数据库、邮件服务器的电脑通常使用可以被多个用户同时使用的分布式网络的服务器操作系统。
Mark:Linux,、UNIX,、Wind ows和OS X服务器都是流行的服务器操作系统。
Henry:太棒了。
操作系统究竟存在于哪里?Mark:在一些诸如手机、电子阅读器的电子设备中,整个操作系统足够小所以可以被储存在只读存储器中。
对于其他大多数的电脑,操作系统很大,所以大部分存储在硬盘上或者固态硬盘上。
Sophie:是的。
在引导程序的过程中,操作系统内核被加载至随机存取存储器中。
内核提供关键的操作系统服务,如内存管理、获取文件。
在电脑运行的过程中,内核一直存在于随机存取存储器中。
其他的部分如定制化工具,被需要的时候会加载至随机存取存储器中。
Henry:我明白了!十分感谢你们。
练习以小组的形式,用右边的其他表达式来替换文中相应的陈述,组成类似的对话。

4. 科技英语中数学公式的读法
3.1 The Decimal System
New Words & Expressions:
3.1 The Decimal SytemThe clumsiness of this system can easily be seen if we try to multiply XII by XIV. Calculating with Roman numerals was so difficult that early mathematicians were forced to perform arithmetic operations almost entirely on abaci, or counting boards, translating their results back into Roman-number form. Pencil-and-paper computations are unbelievably intricate and difficult in such systems. In fact, the ability to perform such operations as addition and multiplication was considered a great accomplishment in earlier civilization. 如果你要用XIV乘XII ,很容易看出这个数字系统是笨拙的。用罗马数字 计算太难了,以至于早期的数字家几乎完全被迫在算盘或演算板完成算 术运算,然后再把结果翻译成罗马数字形式。在这样的数字系统中,纸 和笔运算达到以难置信的复杂和困难程度。事实上,在早期文明中能进 行这样的加法和乘法运算被看作是一项伟大的成就。

Shift registers
A register capable of shifting its binary information in one or both directions is called a shift register.
The simplest possible shift register is one that uses only flip-flops.
The output of a given flip-flop is connected to the D input of the flip-flop at its right. The clock is common to all flip-flops. The serial input determines what goes into the leftmost position during the shift. The serial output is taken from the output of the rightmost flip-flop.

计算机专业英语复习提纲
计算机专业英语复习提纲(注意:加粗单词为重点词汇)第一章1 The Invention of the ComputerENIAC---the Electronic Numerical Integrator and Computer,It was developed by J. Presper Eckert and John Mauchly at the University of Pennsylvania. The project began in 1943and was completed in 1946.ENIAC--- 电子数字积分计算机。
它是由宾夕凡尼亚大学的J. Presper Eckert 和John Mauchly 研制的。
该工程于1943年开始,并于1946年完成。
2 Computer Generations1. First-Generation Computers: 1951~1958First-generation computers were characterized by the use of vacuum tubes as their principal electronic component. V acuum tubes are bulky and produce a lot of heat, so first-generation computers were large and required extensive air conditioning to keep them cool. In addition, because vacuum tubes do not operate very fast, these computers were relatively slow.第一代计算机的特色是使用真空管为其主要电子器件。
真空管体积大且发热严重,因此第一代计算机体积庞大,并且需要大量的空调设备保持冷却。
计算机英语教程(双色版)参考译文
参考译文第1课计算机基础计算机是一个可编程的机器(或者更准确地说,一个可编程的连续状态机器)。
计算机有两种基本类型:模拟计算机和数字计算机。
模拟计算机是模拟设备,即它们有连续的状态而不是离散的有限状态。
一个模拟计算机可以准确地表示小数或无理数,不进行舍入。
模拟计算机几乎只用于实验环境。
数字计算机是可编程的时序状态机器。
数字计算机使用离散状态。
二进制数字计算机使用两个离散状态(如正/负、高/低、通/断)来表示二进制数0和1。
1. 计算机有什么用?计算机的用途非常广泛。
数据处理是商业和金融的工作。
这包括开票、运输及收货、库存管理和类似的业务以及“电子办公”。
科学处理是用计算机支持科学。
这可以是简单地收集和分析原始数据,也可以是复杂地建立自然现象的模型(如气候模型、热力学、核能等)。
多媒体包括创建内容(创作音乐、演奏音乐、录制音乐、编辑电影和视频、特效、动画、插图、排版印刷材料等)和多媒体播放(游戏、DVD、教学材料等)。
2. 计算机的各部分可以十分粗略简单地认为计算机有三个部件:处理器、内存和I/O(输入/输出)。
这三个术语的边界是十分含糊的、不搭界的和不断变化的。
稍微更简单地可以把计算机部件分为五种:算术和逻辑子系统、控制子系统、主存、输入子系统和输出子系统。
2.1 处理器处理器是计算机实际上进行计算的部件。
有时也称作MPU(主处理器单元)或CPU (中央处理单元或中央处理器)。
处理器通常包括运算器(ALU)、控制器(包括处理器标志、标志寄存器或状态寄存器)、内部总线,有时也有一些特殊作用的单元(最常用的特殊作用单元是用于浮点算法的浮点单元)。
一些计算机有多个处理器。
这就叫做多处理计算机。
数字处理器的主要种类有:CISC、RISC、DSP以及它们的混合。
CISC代表复杂指令集计算机。
大型计算机和小型计算机有CISC处理器,厂家为了竞争提供了更有用的指令集。
大部分前两代微型处理器都用CISC。
RISC代表精简指令集计算机。

1.1 The Invention of the Computer
1.1.2 The UNIVAC I
Like other computing pioneers before them, Eckert and Mauchly formed a company in 1947 to develop a commercial computer. The company was called the Eckert-Mauchly Computer Corporation. Their objective was to design and build the Universal Automatic Computer or UNIVAC. Because of difficulties of getting financial support, they had to sell the company to Remington Rand in 1950. Eckert and Mauchly continued to work on the UNIVAC at Remington Rand and completed it in 1951. Known as the UNIVAC I, this machine was the first commercially available computer.
