  1. 1. Unit 1 Text A Computer Basics 1 Hardware The physical portion of the computer. CPU Central processing unit. The computer chip primarily responsible for executing 5 instructions. Monitor The screen for viewing computer information is called a monitor. Motherboard The main printed circuit board in a computer that carries the system buses. It is 10 equipped with sockets to which all processors, memory modules, plug-in cards, daughterboards, or peripheral devices are connected. Memory Computer memory is used to temporarily store data. In reality, computer memory is only capable of remembering sequences of zeros and ones, but by utilizing the binary 15 number system it is possible to produce arbitrary rational numbers and through clever formatting all manner of representations of pictures, sounds, and animations. The most common types of memory are RAM, ROM, and flash. RAM Random access memory. A data storage device for which the order of access to 20 different locations does not affect the speed of access, except for bursts. Data is typically stored in RAM temporarily for use by the process or while the computer is operating. FPM, EDO, SDRAM, DDR, etc. are all types of RAM. ROM Read-only memory is similar to RAM. It only cannot be altered and does not lose its 25 contents when power is removed. Mouse In computer parlance a mouse can be both the physical object moved around to control a pointer on the screen, and the pointer itself. Unlike the animal, the proper plural of computer mouse is “mouses”.
  2. 2. 计算机英语实用教程(第二版) 30 Keyboard A keyboard on a computer is almost identical to a keyboard on a typewriter. Computer keyboards will typically have extra keys; however, some of these keys (common examples 2 include Ctrl, Alt) are meant to be used in conjunction with other keys just like shift on a regular typewriter. Other keys (common examples include Insert, Delete, Home, End, Help, 35 function keys,etc.) are meant to be used independently and often perform editing tasks. Keyboards on different platforms will often look slightly different and have somewhat different collections of keys. Some keyboards even have independent shift lock and caps lock keys. Smaller keyboards with only math-related keys are typically called “keypads”. Disk 40 A disk is a physical object used for storing data. It will not forget its data when it loses power. It is always used in conjunction with a disk drive. Some disks can be removed from their drives, and some cannot. Generally it is possible to write new information to a disk in addition to reading data from it, but this is not always the case. Floppy 45 An extremely common type of removable disk. Floppies do not hold too much data, but most computers are capable of reading them. Note that there are different competing format used for floppies, so that a floppy written by one type of computer might not directly work on another, also sometimes called “diskette”. USB 50 A really fast type of serial port that offers many of the best features of SCSI without the price. Faster than many types of parallel port, a single USB port is capable of chaining many devices without the need of a terminator. USB is much slower (but somewhat less expensive) than Firewire. I/O Port 55 Connection to a CPU that provides a data path between the CPU and external devices, such as a keyboard, display, or reader. It may provide input only, output only, or both input and output.

Ex. 5 通过 Internet 查找资料,借助如“金山词霸”等电子词典和辅助翻译软件,完 成以下技术报告。通过 e-mail 发送给老师,并附上你收集资料的网址。 1. 简述键盘当前的发展状况及性能(附各种最新键盘的图片)。 2. 目前有哪些新颖的鼠标?请附图片与简要描述。 3. 简述最新 PC 性能与价格。 4. 你所知道的可以通过 USB 接口与 PC 相连接的设备有哪些? Word Building 学习英语的关键与难点之一就是记忆单词。机械地逐一记忆单词会花费大量的时间。 而 且 , 在 计 算 机 行 业 中 还 不 断 涌 现 出 一 些 新 构 造 出 来 的 词 , 如 unformat、undelete、resetup、uninstall 等。这些单词往往在字典中查不到。因此,必须学会科 学地记忆单词和识别新词。 其实,英语单词有其内在的结构规律,这就是构词法。掌握了构词法,则可达到举一 反三、见词识义的学习效果。因此,掌握构词法是快速记忆英语单词的捷径。 常用的构词法有合成、转化及派生三种。 1.合成法(compounding) 由两个和两个以上的词合成一个新词的构词方法就叫“合成法”。用合成法构成的词 叫做“复合词”。 复合词可以有三种书写形式:连起来写(如网络 network),分开写(如 汽车站 bus stop),用连字符连在一起(如内置的 built-in)。由三个以上单词构成一个复 合词时常采用第三种方法。例如,现代的 up-to-date ,一对一的 one-to-one ,容易使用的 easy-to-use 。合成词的前一个词常用来说明后一个词,例如,主板 motherboard ,子板 daughterboard。绝大部分合成词的词性由最后一个单词决定,但也有例外,如 up-to-date 就 是形容词。 合成词的构成方法如下: 1)合成名词(compound noun)
  7. 7. (1)名词+名词 wave + length —— wave-length 波长 band + width —— bandwidth 带宽,频带宽度 bench + mark —— benchmark 基准测试 bold + face —— boldface 粗体 clip + board —— clipboard 剪贴板 chip + set —— chipset 芯片组 copy + right —— copyright 版权 data + base —— database 数据库 finger + tip —— fingertip 手指尖 firm + ware —— firmware 固件,硬件 lap + top —— laptop 膝盖,膝面,膝上 screw + driver —— screwdriver 螺丝刀 snail + mail —— snailmail 慢邮件 spread + sheet —— spreadsheet 电子表格;数据表 Web + site —— website 网站 (2)名词+动名词 machine + building —— machine building 机器制造 book + learning —— book learning 书本知识 hand + writing —— handwriting 手写的 (3)动名词+名词 waiting + room —— waiting-room 候车室 building + material —— building material 建筑材料 swimming + pool —— swimming pool 游泳池 (4)形容词+名词 short + hand —— shorthand 速记 hard+ ware —— hardware 硬件 soft + ware —— software 软件 lower + case —— lowercase 下档;小写字母 upper + case —— uppercase 上档;大写字母 broad + band —— broadband 宽波段 fresh + man —— freshman 大(中)学校一年级学生 hard + copy —— hardcopy 硬拷贝 (5)动词+名词 pick + pocket —— pickpocket 小偷 break + water —— breakwater 防水堤 7 (6)副词+动词 第 in + put —— input 输入 1 out + put —— output 输出;产量 章 Unit 1
  8. 8. 计算机英语实用教程(第二版) out + come —— outcome 结果 (7)动词+副词 feed + back —— feedback 反馈 8 get + together —— get-together 联欢会 stand + still —— standstill 停顿 Ex. 6 将 A 栏和 B 栏的单词匹配构成复合单词,再将其翻译成中文。 Column A Column B Chinese meaning of compound word daughter writer soft what plug form key related type in plat pad some ware math put key board in board Structure 及物动词(transitive verb, i.e., vt.)构成的基本句型 英语中及物动词构成的句型最为复杂,掌握了及物动词的句型,也就基本掌握了英 语句型。总体说来及物动词可以构成主动宾、主动双宾、主动宾补这三种基本句型。 这里所讲的三种形式的宾语类似于汉语,是最容易掌握的。 ① 名词做宾语(noun as object) 【例】A disk will not forget its data when it loses power. 电源关闭后,磁盘上的数据不会丢失。 【例】Computer keyboards will typically have extra keys. 计算机的键盘有一些特有的扩展键。 ② that 从句做宾语(that clause as object) 【例】The teacher explained that the most common input device is a keyboard. 老师解释说最常使用的输入设备是键盘。 【例】He has realized that the central processing unit(CPU) is the brain of the computer. 他意识到了,中央处理器是计算机的大脑。
  9. 9. ③ 疑问连词引出从句充当宾语(clauses introduced by wh-words as object) 【例】Do you know why the motherboard is equipped with sockets? 你知道为什么主板上要装备有插槽吗? 【例】I wonder how computer memory can store all manner of representations of pictures, sounds, and animations. 我不理解(想弄明白)计算机内存怎么能够存储所有代表图片、声音和动画的数据。 Ex. 7 用名词做宾语将下面的汉语译成英语。 1. 访问不同地方的顺序不影响访问速度。 2. 我们一般将数据临时存放在 RAM 中。 3. 鼠标器能够控制屏幕上的光标指示器。 4. 有的键盘有单独的上下档锁定键和大写字母锁定键。 Ex. 8 用 that 从句做宾语将下面的汉语译成英语。 1. 你应该知道,你不仅仅能够读取磁盘上的数据,也能够往上面写新的信息。 2. 你应该意识到,软盘容纳不了多少数据。 3. 我们计算机老师说,USB 要比火线慢多了。 4. 我认为 CPU 主要责任是执行指令。 Ex. 9 用疑问连词引出的从句充当宾语翻译下列各句。 1. 请说说显示器是干什么用的。 2. 我想知道为什么内存能够存储任何的有理数。 3. 我不知道是不是所有磁盘都可以从驱动器中取出来。 4. 你能够建议一下我在何处买一个 U 盘吗? Text B 1 PC In its more general usage, a PC (personal computer) is a computer designed for use by one person at a time. Prior to the PC, computers were designed for (and only affordable by) companies who attached terminals for multiple users to a single large computer whose 5 resources were shared among all users. Beginning in the late 1980s, technology advances made it feasible to build a small computer that an individual could own and use. The term “PC” is also commonly used to describe an “IBM-compatible” personal computer in contradistinction to an Apple Macintosh computer. The distinction is both 9 technical and cultural. The “IBM-compatible” PC is one with an Intel microprocessor 第 10 architecture and an operating system such as DOS or Windows that is written to use the 1 Intel microprocessor. The Apple Macintosh uses a Motorola microprocessor architecture 章 Unit 1
  10. 10. 计算机英语实用教程(第二版) and a proprietary operating system. The “IBM-compatible” PC is associated with business (as well as home) use. The “Mac”, known for its more intuitive user interface, is associated with graphic design and desktop publishing. 10 Keyboard 15 On most computers, a keyboard is the primary text input device. (The mouse is also a primary input device but lacks the ability to easily transmit textual information.) The keyboard also contains certain standard function keys, such as the Escape key, tab and cursor movement keys, shift and control keys, and sometimes other manufacturer- customized keys. The computer keyboard uses the same key arrangement as the mechanical and 20 electronic typewriter keyboards that preceded the computer. The standard arrangement of alphabetic keys is known as the Qwerty (pronounced KWEHR-tee) keyboard, its name deriving from the arrangement of the six keys at the upper left of the three rows of alphabetic keys. This arrangement, invented for one of the earliest mechanical typewriters, dates back to the 1870s. Another well-known key arrangement is the Dvorak (pronounced 25 duh-VOR-ak, not like the Czech composer) system, which was designed to be easier to learn and use. The Dvorak keyboard was designed with the most common consonants on one side of the middle or home row and the vowels on the other side so that typing tends to alternate key strokes back and forth between hands. Although the Dvorak keyboard has never been widely used, it has adherents. Qwerty keyboard 30 The Qwerty (pronounced KWEHR-tee) keyboard is the standard typewriter and computer keyboard in countries that use a Latin-based alphabet. Qwerty refers to the first six letters on the upper row of the keyboard. The key arrangement was devised by Christopher Latham Sholes whose “Type-Writer”, as it was then called, was first mass- produced in 1874. Since that time, it has become what may be the most ubiquitous machine-user interface of all time. 35 The Qwerty arrangement was intended to reduce the jamming of typebars as they moved to strike ink on paper. Separating certain letters from each other on the keyboard reduced the amount of jamming. In 1932, August Dvorak developed what was intended to be a faster keyboard, putting the vowels and the five most common consonants in the middle row, with the idea that an alternating rhythm would be established between left and right hands. Although the Dvorak keyboard has many adherents, it has never overcome the 40 culture of learning to type on a Qwerty. Mouse A mouse is a small device that a computer user pushes across a desk surface in order to point to a place on a display screen and to select one or more actions to take from that position. The mouse first became a widely-used computer tool when Apple Computer made 45 it a standard part of the Apple Macintosh. Today, the mouse is an integral part of the
  11. 11. graphical user interface (GUI) of any personal computer. The mouse apparently got its name by being about the same size and color as a toy mouse. A mouse consists of a metal or plastic housing or casing, a ball that sticks out of the bottom of the casing and is rolled on a flat surface, one or more buttons on the top of the 50 casing, and a cable that connects the mouse to the computer. As the ball is moved over the surface in any direction, a sensor sends impulses to the computer that causes a mouse- responsive program to reposition a visible indicator (called a cursor) on the display screen. The positioning is relative to some variable starting place. Viewing the cursor’s present position, the user readjusts the position by moving the mouse. 55 The most conventional kind of mouse has two buttons on top: the left one is used most frequently. In the Windows operating systems, it lets the user click once to send a “Select” indication that provides the user with feedback that a particular position has been selected for further action. The next click on a selected position or two quick clicks on it causes a particular action to take place on the selected object. For example, in Windows operating 60 systems, it causes a program associated with that object to be started. The second button, on the right, usually provides some less-frequently needed capability. For example, when viewing a Web page, you can click on an image to get a popup menu that, among other things, lets you save the image on your hard disk. Some mouses have a third button for additional capabilities. Some mouse manufacturers also provide a version for left-handed people. 65 Windows 95 and other operating systems let the user adjust the sensitivity of the mouse, including how fast it moves across the screen, and the amount of time that must elapse within a “double click”. In some systems, the user can also choose among several different cursor appearances. Some people use a mousepad to improve traction for the mouse ball. Although the mouse has become a familiar part of the personal computer, its design 70 continues to evolve and there continues to be other approaches to pointing or positioning on a display. Notebook computers include built-in mouse devices that let you control the cursor by rolling your finger over a built-in trackball. IBM’s scrollpoint mouse adds a small “stick” between two mouse buttons that lets you scroll a Web page or other content up or down and right or left. Users of graphic design and CAD applications can use a stylus and a specially-sensitive pad to draw as well as move the cursor. Other display screen-positioning 75 ideas include a video camera that tracks the user’s eye movement and places the cursor accordingly.

Text A 参 考 译 文 计算机基础 硬件 计算机的物理部件。 CPU 中央处理器。主要负责执行指令的计算机芯片。 监视器 用于查看计算机信息的屏幕叫做“监视器”。 主板 计算机中主要的印刷电路板,它带有系统总线。板上装备有插槽,这样所有处理器、 内存模块、即插即用卡、子板等均可插在主板上。这些插槽也可以用来连接外围设备。 内存 计算机的内存用来临时存储数据。事实上,计算机内存只能记忆 0 和 1 组成的序列, 但通过二进制系统,它也可以存储任何的有理数。 对于所有代表图片、声音和动画的数据, 经过巧妙的格式处理后,内存也可以存储。常用的内存有 RAM、ROM 和闪存几种。 RAM 随机存取存储器。一种数据存储设备。对它而言,除非有爆发性访问,否则访问顺序 对访问速度没有影响。一般说来,程序临时需要的数据或者计算机正在操作使用的数据存 储在 RAM 中。FPM、EDO、SDRAM、DDR 等均属 RAM。 ROM 只读存储器类似于 RAM,不过其中的数据不能改变,关机后也不丢失。 鼠标 用计算机业界的行业术语来说,鼠标既指来回移动以控制屏幕上光标指示器的物理 设备,也指屏幕上的光标指示器本身。与 mouse 表示动物老鼠不同,在它表示计算机鼠标 时,mouses 才是其正确的复数形式。 键盘 计算机的键盘与打字机的键盘差不多。然而,计算机键盘有一些特有的扩展键。这些 键中的某些键(普通的如 Ctrl、Alt)与其他键联合使用,有点像正规打字机上的换挡键。 其他键(普通的如 Insert、Delete、Home、 、 End Help 及所有功能(F)键等)可以独立地使用, 通常执行编辑任务。 不同平台的键盘看上去常常稍有不同,即安排的键有些不同。 有些键盘 甚至有独立的换挡和大写字母锁定键。较小键盘上只有与数字相关的键,叫做“数字小键 盘”。 磁盘 17 磁盘是用于存储数据的物理设备。电源关闭后数据不会丢失。它总是与磁盘驱动器一 第 起使用。 某些磁盘可以从磁盘驱动器中取出,某些则不能。 一般情况下,除了可以读取磁盘 1 中的信息外,也可以把新的信息写到磁盘上,但情况并不总是如此。 章 Unit 1
  18. 18. 计算机英语实用教程(第二版) 软盘 一种很常用的可移动磁盘。 软盘不能保存太多的数据,但绝大多数计算机都能够读取它 们的信息。 值得注意的是,出于竞争,软盘有不同的格式,所以被一个计算机写过的软盘到 18 其他计算机上可能不能直接使用。表示软盘的单词除了用 floppy 外,还可以用 diskette(磁 盘)。 USB 一种确实快的串口类型,具有 SCSI 的大部分性能但价钱要贵一些。 由于单个的 USB 接 口比许多并口速度快,它可以连接许多设备而无需端接设备。USB 比火线慢(但便宜一点 点)。 I/O 接口 连接到 CPU,为 CPU 和外部设备(如键盘、显示器或阅读机)提供数据通路。 它可以 只输入或只输出,也可以既输入又输出。
