23、ograms are the instructions that tell the computer how to process data into the form you want.Software,as we mentioned,is another name for programs.In most cases,the words software and programs are interchangeable.For example,your favorite computer game is a program.In order for your computer to kno

24、w how to play that game,you(or your parents)must first install the program from the game software-usually a CD.Installing the program means that you are copying the program or instructions that are stored on the CD onto your computers hard drive.Programs can also be downloaded from the internet dire

25、ctly to your hard drive.Many programs(especially games)are very large and would take up lots of memory space on your hard drive.To keep that from happening,these programs are designed to only copy part of the program onto your computer.The rest of the program stays on the software.The program cannot

31、slators that allow people to work with computers without learning the computers language.,What are Software Applications?,科技英语的语言特点（）科学技术的研究对象、任务及方法决定了在科技领域中，表达思想要严谨，用词要准确，阐述问题要有逻辑性、科学性和系统性，说理要清晰、简洁、明快等。所以，科技文献资料的叙述以抽象性、概念性和高度的逻辑性为其主要特征，形成了科技语言所特有的语言表达方式。我们认为，从宏观上了解计算机科学及技术领域中文体的语言特征，掌握其遣词造句方面的基本语言风

32、格和基本语言特点，对于我们阅读、理解和翻译不同类型的英语计算机科技文献资料，具有十分重要的意义。任何一种语言(language)均是由语音(pronunciation)、词汇(vocabulary)和语法(grammar)三大部分构成的。词汇是基础，句法是遣词造句的规则，而语音则是语言的外壳。因此，以下我们将从科技英语的“用词的特点”和“用句的特点”来解析科技英语的语言特点。,What are Software Applications?,科技英语用词的特点1多用表示行为的动词代替存在的动词“Be”科技英语写作用词讲究规范，力求明白、简洁、精确，不允许有虚构，由此选择了动态的动词词组来实现其目

33、的。例如：Harries was the first to utilize1 the reactivity of the double boned in order to gain2 an insight into the nature of the rubber molecule,and the evidence is based3 almost entirely on his ozonolysis experiments.By passing4 oxygen containing5 6%of ozone into a solution of rubber in chloroform or

34、ethyl acetate,Harries obtained 6 a glassy explosive mass of the composition(C5HgO3).Decomposition of the ozonide with water afforded7 levulinic aldehyed.These experiments were later verified8 and extended9 by Purnmerer,who was able to account10 for about 95%of the carbon skeleton in the form of deco

35、mposition products,almost 90%of which consisted11 of levulinic compounds.This means12 that the isoprene units must be linked13 bead to tail.(The Chemist,1951)在这段中我们看到作者用了13个不同形态的行为动词，使整段叙述的行为过程给人以强烈的动感。由于科技英语在大多数情况下都是描述行为、过程、现象及发展等，因此多用表行为的动词。表行为的动词具有较鲜明的动态感，较生动，但表示存在的动词给人以静态感，比较凝滞。,What are Softwar

36、e Applications?,2使用语义确切的强动词代替空泛的弱动词在英语中动词可以分为两类：强动词和弱动词。强动词有具体的行为，如weld,cut,break,inject等等；弱动词本身并无具体行动，如 verb to be,do,make include 等等。强动词常常可以给出明确的语义，使语句直截了当，一目了然，但弱动词可能带来较含糊的语句，这需读者去琢磨才能明白其中的含义。例如：1）He has made several key sensor exploitation technological developments.2）He has developed several ke

37、y sensor exploitation technologies.例句1中，用了made这个无行动的弱动词，随后必有development；而在例句2中，直接用了develop这个强动词，使句子清新明朗。,What are Software Applications?,3常用由动词派生的名词科技英语常用由动词派生的名词，这类名词的词根多出自属于及物动词的名词，具有“Transitivity”(他动性)。充分利用动词名词化手段，可以有效地简化叙事层次和结构，减少使用句子或从句的频率，使文章更加直接、紧凑、简洁明了。例如：the discovery of interferon 干扰素的发现 t

38、he standardization of the series 系列的标准化 the generation of heat by friction 磨擦生热,What are Software Applications?,4多用名词群科技英语中名词修饰名词随处可见，有时是两个名词构成的名词词组来修饰另一个名词。这种名词词组做定语比介词短语显得更加简短快捷，是科技论文中常见的表达方式之一。例如：computer system organization 计算机系统的组成 data transmission system 数据传输系统 dot matrix printer 点阵式打印机 voice

39、 recognition equipment 声音识别设备,What are Software Applications?,5广用缩略词在科技英语文章中，常常看到缩略词，这些词已固化成为科技英语专业中的专业词。例如：LCS：Large Capacity Storage 大容量存储器LPL：List Programming Language 表格程序设计语言LSI：Large Scale Integration 大规模集成电路MCP：Master Control Program 主控程序ML：Machine Language 机器语言 MOS：Metal Oxide Semiconductor

40、金属氧化物半导体NC：Numerical Control 数字控制OSI：Open System Interconnection 开放系统互连PCC：Program-Controlled Computer 程序控制计算机PPI：Programmable Peripheral Interface 并行传送接口RAM：Random Access Memory随机存取存储器 RMOS：Refractory Metal-Oxide-Semiconductor耐热的金属氧化物半导体RWM：Read Write Memory 读写存储器,What are Software Applications?,科技

41、英语属于正式书面文体，在词汇方面，除了科技专门术语外，科技英语使用的所有词语，包括普通词汇和技术性词汇在内，大多数属于正式书面语体的范畴，尽管这些词语在普通英语和文学英语中也使用，但其出现的频率远不及科技英语。Write the whole name of the following words.FIFO AGC CNC DOSSCC VGA RMDIR PCCSTX MCP LCS ECCPractical Writing：咨询信咨询信主要包括下列内容：1）写信的目的；2）介绍背景；3）询问详情；4）表示感谢，期待回信，询问进一步的信息。,What are Software Applicat
