文档介绍：科技英语English for Science and Technology主讲:刘永勤学院:物理与电气工程学院School of Physics and Electrical Engineering科技英语的语法特点(Grammar)科技文章文体的特点是:语言简练、结构严谨、逻辑性强、原理概念清楚、重点突出、段落章节分明。科技英语在用语、语法结构及表达方式上有其自身的特点。(1)大量使用专业词汇和半专业词汇。例如,calculus(微积分学)、bandwidth(带宽),flip-flop(触发器)等是专业词汇。而series可作“级数”,也可作“串联”解。(2)大量使用词缀和词根。例如以tele-构成的单词有30多个。(3)较多使用缩略词。常见的如PCM(pulse-coded modulation),CDMA(code division multiple access码分多址),DSP等。(4)词性变换多。例如,sound一词做名词时,常译为“声音、语音”,做动词时,常译为“听起来”,做形容词时,以“合理的、健全的”较为多见。Sound travels slower than light .She sounded a note of child has a sound mind in a sound 's very sound advice; you should take (1)常用一般现在时态,表示真理或客观规律的陈述。Vector and matrix techniques provide the framework for much of the developments in modern 。(2)广泛使用被动语态,强调所论述的客观事物。Chapters 7 and 8 are devoted to the calculus of functions of one variable and,recognizing again the mixed background knowledge in mathematics of the students,thebasic ideas and techniques of differentiation and integration are reviewed in chapter 7. 第7章和第8章讨论单变量函数的微积分,考虑到学生数学基础参差不齐,第7章复习微分与积分的基本概念与方法。(3)普遍使用名词词组及名词化结构,强调客观存在的事实而非某一行为,故常使用表示动作或状态的抽象名词。Television is the transmission and reception of images of moving objects by radio 。(4)使用非限定动词,使句子简明。The calculus,aided by analytic geometry,proved to be astonishingly powerful and capable of attacking hosts of problems that had been baffling and quite unassailable in earlier ,能够解决许多困扰已久甚至以前认为无法解决的问题。(1)较常使用“无生命主语+及物动词+宾语(+宾语补足语)”句型。Chapter 6 provides a basic introduction to the ideas of sequences,series and 、级数及极限等基本概念。(2)常用it 做形式主语或形式宾语。It has been proved that induced voltage causes a current to flow in opposition to the force producing ,感应电压使电流的方向与产生电流的磁场力方向相反。The invention of radio has made it possible for mankind municate with each other over a long 。(3)尽量用紧凑型状语从句而不用完整句。While designed primarily for use by engineering student
