A clean water source, water is not contaminated. To have a reliable power supply, not only to maintain normal lighting,Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, 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.

Computer hardware in and of itself does not provide a particularly useful mind tool. To be useful, a computer 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。

计算机英语参考答案
附录参考答案Unit 1〖Ex. 1〗根据课文内容回答问题(1) A general-purpose computer has four main sections. They are the arithmetic and logic unit (ALU),the control unit, the memory, and the input and output devices, collectively termed I/O. They are interconnected by busses, often made of groups of wires.(2) The control unit is often called a control system or central controller.(3) ●Read the code for the next instruction from the cell indicated by the program counter.●Decode the numerical code for the instruction into a set of commands or signals for each of the other systems.●Increment the program counter so it points to the next instruction.●Read whatever data the instruction requires from cells in memory, or perhaps from an input device. The location of this required data is typically stored within the instruction code.●Provide the necessary data to an ALU or register.●If the instruction requires an ALU or specialized hardware to complete, instruct the hardware to perform the requested operation.●Write the result from the ALU back to a memory location or to a register or perhaps an output device.●Jump back to the first step.(4) The two classes of operations ALU is capable of performing are arithmetic and logic.(5) Logic operations involve Boolean logic: AND, OR, XOR and NOT.(6) A computer's memory can be viewed as a list of cells into which numbers can be placed or read. Each cell has a numbered "address" and can store a single number.(7) The two principal varieties of computer main memory are random access memory or RAM andread-only memory or ROM.(8) In a PC, the specialized program called the BIOS orchestrates loading the computer's operating system from the hard disk drive into RAM whenever the computer is turned on or reset.(9) Software that is stored in ROM is often called firmware because it is notionally more like hardwarethan software.185(10) I/O is the means by which a computer receives information from the outside world and sendsresults back.〖Ex. 2〗根据下面的英文解释,写出相应的英文词汇(1) input (2) microprocessor (3) program (4) bus (5) hardware (6) memory (7) output (8) cell(9) register (10) address〖Ex. 3〗把下列句子翻译为中文(1) 他进城的目的是买一台新计算机。

Fill in each of the blanks with one of the words given in the following list, making changes if necessary:We can define a computer as a device that accepts input, processes data, stores data, and produces output. According to the mode of processing, computers are either analog or digital. They can also 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 historic significance, such as UNIVAC (通用自动计算机), 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. T ranslate the following passage from English into Chinese: 计算机将变得更加先进,也将变得更加容易使用。

教材特点
词性转换多
英语单词有不少是多性词,即既是名词,又可用作动词、形 容词、介词或副词,字形无殊,功能各异,含义也各不相同,如 不仔细观察,必致谬误。例如, light 名词:(启发)in (the)light of由于,根据; (光)high light(s) 强光,精华;(灯)safety light 安全指 示灯 形容词:(轻)light industry 轻工业; (明亮)light room 明亮的房间; (淡)light blue 淡蓝色; (薄)light coating 薄涂层 动词: (点燃)light up the lamp 点灯 副词: (轻快)travel light 轻装旅行 (容易)light come, light go 来得容易去得快 诸如此类的词性转换,在科技英语中屡见不鲜,几乎每个技 术名词都可转换为同义的形容词。词性转换增加了英语的灵活性 和表现力,读者必须从上下文判明用词在句中是何种词性,而且 含义如何,才能对全句得到正确无误的理解。
