二．短文翻译练习

1. 近年来，对于分子生物学、植物遗传学、生物化学以及相关领域的前沿研究，中国政府给予了高度的优先权，这样能够增加农作物和牲畜产量。未来的几十年，科技肯定是中国食品保障的重要因素之一。中国人口必然增长，经济会持续发展，而在庄稼用地和水资源方面受到严重制约，因此，除了实现农业现代化，别无它法。(molecular biology, plant genetics, biochemistry)

In recent years the Chinese government has also given high priority to advanced research in molecular biology, plant genetics, biotechnology, and related fields, which is aimed at increasing crop yields and livestock productivity. Science and technology will certainly be among the key factors in China’s food security during the next few decades. With China’s inevitable population growth, its likely economic development, and its serious constraints in cropland and water, the country has no other choice than to modernize its agricultural sector.

2. As oil is found deep in the ground, its presence cannot be determined by a study of the surface. Consequently, a geological survey of the underground rock structure must be carried out. If it is thought that the rocks in a certain area contain oil, a “drilling rig”is assembled. The most obvious part of a drilling rig is called “a derrick”. It is used to lift sections of pipe, which are lowered into the hole made by the drill. As the hole is being drilled, a steel pipe is pushed down to prevent the sides from falling in. If oil is struck, a cover is firmly fixed to the top of the pipe and the oil is allowed to escape through a series of values.

石油埋藏于地层深处。因此,仅研究地层表面, 无法确定有无石油,必须勘测地下的岩石结构。如果确定了某一区域的岩石蕴藏着石油,就此安装钻机。它的主要部分是机架,用以撑起一节一节的钢管,让其下到井孔。一边钻井,一边下钢管,以防周围土层塌陷。一旦出油,就紧固管盖,让油从各个阀门喷出。

Winners successfully make the transition from total helplessness to independence, and then to interdependence. Losers do not. 虽然人们生来要成功，然而，他们同样生来就是无助的，完全依靠环境。成功者成功地从完全不能自立过渡到了独立，然后过渡到相互依靠。失败者则不然。 4.Darwin was convinced that the loss of the tastes in music and drawing was not only a loss of happiness, but might possibly be injurious to the intellect, and more probably to the moral character. 达尔文认为，失去对音乐和绘画方面的兴趣，不仅失去了幸福，而且还可能损伤智力，甚至可能会伤害道德。 5.No eating tools on the Chinese dinner table are more magical and distinctive than the chopsticks. 中餐桌上最神奇,最有特色的用餐工具莫过于筷子. 6.It is not on the shores of continents, nor in the coastal islands, however, that the soul of the great Pacific is found. It lies far out where the fabled South Sea Islands are scattered over the huge ocean like stars in the sky. 然而，浩瀚的太平洋最精美之处不在其大陆海岸，也不在沿海诸岛，而是在远离陆地的海域。在那里，富有神奇色彩的南太平洋诸岛像天上的繁星一样散布在广阔的海面上。 7.Circumstances and people are constantly changing.

EST (English for Science & Technology or Technical English or Scientific English) is a special language variety widely used in the fields of science and technology. It’s believed that it first came to being in the 1950s along with the rapid development of science and technology, and it many researchers and scholars began to conduct investigation of this common feature of this special genre including reading comprehension, writing and even translation. 2. What are stylistic features of EST?

小议科技英语翻译技巧

小议科技英语翻译技巧 科技文体崇尚严谨周密，概念准确，逻辑性强，行文简练，重点突出，句式严整，少有变化，常用前置性陈述，即在句中将主要信息尽量前置，通过主语传递主要信息。科技文章文体的特点是：清晰、准确、精练、严密。那末，科技文章的语言结构特色在翻译过程中如何处理，这是进行英汉科技翻译时需要探讨的问题。现分述如下： 一、大量使用名词化结构 大量使用名词化结构（Nominalization）是科技英语的特点之一。因为科技文体要求行文简洁、表达客观、内容确切、信息量大、强调存在的事实。而非某一行为。 Archimedes first discovered the principle of displacement of water by solid bodies. 阿基米德最先发展固体排水的原理。 句中of displacement of water by solid bodies 系名词化结构，一方面简化了同位语从句，另一方强调displacement 这一事实。 The rotation of the earth on its own axis causes the change from day to night. 地球绕轴自转，引起昼夜的变化。 名词化结构the rotation of the earth on its own axis 使复合句简化成简单句，而且使表达的概念更加确切严密。 If you use firebricks round the walls of the boiler, the heat loss, can be considerably reduced. 炉壁采用耐火砖可大大降低热耗。 科技英语所表述的是客观规律，因之要尽量避免使用第一、二人称；此外，要使主要的信息置于句首。 Television is the transmission and reception of images of moving objects by radio waves. 电视通过无线电波发射和接受活动物体的图象。 名词化结构the transmission and reception of images of moving objects by radio waves 强调客观事实，而"谓语动词则着重其发射和接受的能力。 二、广泛使用被动语句 根据英国利兹大学John Swales 的统计，科技英语中的谓语至少三分之一是被动态。这是因为科技文章侧重叙事推理，强调客观准确。第一、二人称使用过多，会造成主观臆断的印象。因此尽量使用第三人称叙述，采用被动语态，例如：Attention must be paid to the working temperature of the machine.应当注意机器的工作温度。而很少说：You must pay attention to the working temperature of the machine .你们必须注意机器的工作温度。此外，如前所述，科技文章将主要信息前置，放在主语部份。这也是广泛使用被动态的主要原因。试观察并比较下列两段短文的主语。 We can store electrical energy in two metal plates separated by an insulating medium. We call such a device a capacitor, or a condenser, and its ability to store electrical energy capacitance .It is measured in farads. 电能可储存在由一绝缘介质隔开的两块金属极板内。这样的装置称之为电容器，

科技英语中专业术语的翻译

科技英语中专业术语的 翻译 集团文件版本号：（M928-T898-M248-WU2669-I2896-DQ586-M1988）

科技英语中专业术语的翻译 1.意译：根据科技术语的含义，将其翻译成汉语里和它完全对等的名词就叫意译。对单个词语来说，意译也就是直译。意译法是最常用的翻译方法，它能使读者直接了解术语的含义。例子如下： ①firewall ．．．．．．．． ：防火墙 ②data mining ．．．．．．．．．． ：数据挖掘 ③automatic program control ．．．．．．．．．．．．．．．．．．．．．．． ：自动程序控制 2.形译：英语中有些科技术语的前半部分是表示该术语形象的字母或单词，翻译成汉语时可把这一部分翻译成表示具体形象的词，或保留原来的字母，这就叫形译。例子如下： I ．-．bar ．．． 工字钢、工字条；O ．-．ring ．．．． 环形圈；twist ．．．．．-．drill ．．．．．麻花钻；X ．-．Ray ．．．X 光；α．-．brass ．．．．． α黄铜[1] 3.音译：根据英语发音翻译成汉语里相应的词。科技英语中某些有专业名词构成的术语、单位名称、新型材料的名称等，在翻译时都可采用音译法。例子如下： gene ．．．． 基因；quark ．．．．． 夸克；Pentium ．．．．．．． 奔腾 celluloid ．．．．．．．．． 赛璐璐；nylon ．．．．． 尼龙 Hertz ．．．．．（Hz ）赫兹（频率单位）；lumen ．．．．．流明（光通量单位） 4.缩写词：英语首字母缩写词在科技新词中占很大比重，这类词如果译成汉语，就显得拖沓冗长，因此很多情况下干脆不翻译。例子如下： CPU ．．．：．C ．entral Processing Unit ．．．．．．．．．．．．．．．．．．．．(中央处理器) ASCII ．．．．．：．American S ．．．．．．．．．tandard ．．．．．．． C ．ode ．．． for ．．． I ．nformation ．．．．．．．．．． I ．nterchange ．．．．．．．．．． (美国信息交换标准码) ATM ．．．：．A ．synchronous ．．．．．．．．．．． T ．ransfer ．．．．．．． M ．ode ．．． (异步传输方式) 一些国际组织的缩写也常采用这种办法。例子如下： WTO ．．．(国际贸易组织)；UNESCO ．．．．．．(联合国教科文组织)；WHO ．．．(世界卫生组织)；IOC ．．． (国际奥委会)

科技英语翻译的原则_方法及技巧.

翻译是把一种语言里已经表达出来的事物用另一种语言准确流畅地进行重新表达的过程。与其他题材的文章相比,科技专业文章在内容、表达形式和风格上有很大的差别,具有科技性强、专业性强、逻辑严密、表达要求简练的特点,在翻译上力求准确全面、严谨明确和通顺简练。 1科技英语翻译遵循的基本原则 从科技文章的特点来看,大多具有以下几个特征:述说事理、逻辑性强、结构严密、术语繁多,语言严谨、数据精确。这就要求译文必须概念清楚、条理分明、逻辑正确、数据无误,尤其对定义、定律、公式、图表、结论等更应特别注意。科技英语作为特殊英语的一个分支,在词汇构成、遣词造句等方面都有其自身的特点,其语法结构不十分严密、语言习惯和汉语也有不少差别、词汇量大、词语繁多,因此科技英语翻译起来比较困难。另外,科技文章比较重视叙事逻辑上的连贯及表达上的明晰与畅达; 避免行文晦涩,避免表露个人感情,避免论证上的主观随意性。因此,科技英语翻译力求少用或不用描述性形容词以及具有抒情作用的副词、感叹词及疑问词,而是大量使用科技词汇、专业技术用语,译者应尊重客观事实,不能随意改动数据、回避不易翻译的文字,更不能加进自己的主观想象,进行自由翻译。 我国著名翻译家严复提出的“信、达、雅”三准则一直为不少翻译工作者所接受。 “信”指的是译文要忠实于原文,“达”是指译文的通顺达意,“雅”指的是译文的用词修辞。三准则体现了译文和原文信息等值这一基本要领。 “信、达、雅”的翻译准则对各种英语文体的翻译实践都具有指导意义,是衡量一篇译文好坏的标准,也同样适用于科技文献的翻译。由于科技文章特有的文体特征,与其他类文章相比,其“达”和“雅”的内涵不同,它要求在准确传达信息的基础上,使译文更加简洁明快,流畅通顺。2科技英语翻译的基本方法
