Translation Skill 专业英语翻译技巧,Characteristics of Specialty English （科技英语的特点） Translation Skill （英语科技论文翻译技巧）,Characteristics of Language Structure ：（语言结构特点）,Nouns （大量使用名词化结构）； Passive sentences （广泛使用被动句）； Non-finite verbs（非限定动词）； Postpositional attributives（后置定语）； Long sentences（长句）。,科技英语要求行文简洁、表达客观、内容准确、信息量大，常强调存在的事实，而非某一行为，所以大量使用名词化结构。,Nouns （大量使用名词化结构）,The earth rotates on its own axis, which causes the change from day to night. The rotation of the earth on own axis causes the change from day to night.,科技文章侧重叙事、推理，强调客观、准确，因而大量采用第三人称叙述，使用被动语态。过多使用第一、第二人称，会造成主观臆断的现象。科技英语中的谓语至少三分之一是被动语态。,Passive sentences （广泛使用被动句）,The safety policy should be put into practice through careful planning of the safety activities. Occupational safety and health has received increasing attention due to its undeniable influence on economic development and social stability.,由于科技文章要求书写简练、结构紧凑，因而常常使用分词短语代替定语从句；使用分词独立结构代替状语从句或并列分句；使用不定式代替各种从句，“介词+动名词短语”代替定语从句或状语从句。这样，既可缩短句子，又比较醒目。,Non-finite verbs（非限定动词）,Organizational culture is a major component affecting organizational performance and behavior. A safety policy is the management s expression of the direction to be followed in the organization. The most important aim of safety management is to maintain and promote workers health and safety at work.,大量使用后置定语是科技文章的特点之一。常用的句子结构形式有：介词短语后置、形容词及形容词短语后置、副词后置、定语从句后置。,Postpositional attributives（后置定语）,In small and medium-sized companies, the safety manager and the safety representative often have other duties besides their health and safety tasks. (介词短语后置) The safety managers role is to act an expert who is aware of the health and safety legislation and other obligations concerning the company. (定语从句后置) The efforts necessary to assure that sufficient emphasis is placed on system safety are often organized into formal programs. (“形容词短语+从句”后置),为了表达一个复杂概念，使之逻辑严密，科技文章中常常出现许多长句。,Long Sentences （长句）,One comprehensive definition for an organizational culture has been presented by Schein who has said that organizational culture is “a pattern of basic assumptions-invented, discovered, or developed by a given group as it learns to cope with its problems of external adaptation and internal integration-that has worked well enough to be considered valid and, therefore, to be taught to new members as the correct way to perceive, think, and feel in relation to those problems”.,Translation Skill Semantic Extension （翻译技巧 词义引申）,Nouns （词义转译）； Concretizing （词义具体化）； Abstracting（词义抽象化）； （词的搭配）。,词义的引申是指在一个词所具有的原始意义的基础上，根据上下文和逻辑关系进一步加以引申，选择适当确切的目标语词语来表达，避免生搬硬套地逐句死译，使译文更加通顺流畅。值得注意的是，词义的引申不得超出原始意义所允许的范围。,词 义 转 译,翻译时，如果完全生搬硬套字典所给的字面意思，“对号入座”，会使译文生硬晦涩，含糊不清，甚至令人不知所云。因此，遇到一些无法直译的词或词组时，应根据上下文和原词的字面意思，作适当的转化。,Like any precision device, the monitor of methane requires careful treatment. 译：跟任何精密仪器一样，瓦斯监测仪也需要精心维护。（不译“待遇”） The factors which are likely to influence investment spending do not stop here. 译：可能影响投资开支的因素并不止这些。（不译“不停留在这里”） Solar energy seems to offer more hope than any other source of energy. 译：太阳能似乎比其他能源更有前途。（不译“提供更多希望”）,Whether you like it or not, globalization is here to stay.

译：我们的产品如果适当地定期检修，至少可以使用20年。 （不译“看见20年的服务”） International business as a field of management training deals with the special features of business activities that cross national boundaries. 译：作为管理训练一个领域的国际商务具有跨国商务活动的专门特征。（不译“安排，处理，涉及，做生意”）,词义的具体化,英语中常用代表抽象意义的词表示一种具体事物，译成汉语时一般须作具体化的引申，否则意义会不明朗。因此，翻译时应根据汉语的表达习惯，把文中抽象笼统的词语引申为意义明确具体的词语。,The purpose of a driller is to holes. 译：钻机的功能是钻孔。（不译“洞”） There is more to their life than political and social and economic problem, more than transient everydayness. 译：他们的生活远不止那些政治的、社会的和经济的问题，远不止一时的柴米油盐问题。（不译“日常性”） The factory is famous

demanding the setting up of an Arab common market 译：许多人要求建立阿拉伯共同市场。（不译“许多声音”）,词义的抽象化,翻译时把原文中词义较具体的词引申为词义较抽象的词，或把词义较形象的词引申为词义较一般的词。,The major contributors in component technology have been the semi-conductor components. 译：元件技术中起主要作用的是半导体元件。（不译”主要贡献者“） The interest rates have see-sawed between 10 and 15 percent. 译：利率一直在10到15之间不断波动。（不译“跷跷板一上一下的交替摆动” ） There were times when emigration bottleneck was extremely rigid and nobody was allowed to leave the country out of his personal preference. 译：过去有过这种情况：移民限制极为严格，不允许任何人出于个人考虑而迁居他国。（bottleneck不译“瓶颈”或“（交通）狭口”，preference不译“偏爱” ） There are three steps which must be taken before we graduate from the integrated circuit technology. 译：我们要完全掌握集成电路，还必须经过三个阶段。（不译”毕业于“）,词的搭配,翻译时遇到动词、形容词与名词搭配时，应根据汉语的搭配习惯，而不应受原文字面意义的束缚。,The iron ore used to make steel comes from open-pit and underground mines. 译：炼钢用的铁矿石来自露天开采的矿山和地下矿井。（不译“制造刚”） An insulator offers a very high resistance to the passage through which electric current goes.

译：他便在她身边不停地飞来飞去，用他的翅膀点水，激起许多银色的连猗。(touch不译“触摸”、“触及”，make不译“制造”、“做出”、“使”),Translation Skill Semantic Extension （翻译技巧 词量增减）,Nouns （词量增加）； Concretizing （词量减少）。,词量增减是指在英译汉时，根据汉语的习惯，在译文中增加一些原文中无其形而有其意的词，或减去原文中某些在译文中属于多于的词。,词量增加,Mater can be changed into energy, and energy into mater. 译：物质可以转化为能，能也可以转化为物质。（增补英语中省略的词） The best conductor has the least resistance and the poorest has the greatest. 译：最好的导体电阻最小，最差的导体电阻最大（增补英语中省略的词） If A is equal to D, A plus B equals D plus B. 译：若A=D，则A+B=D+B（增加关联词）,The first electronic computers used vacuum tubes and other components, and this made the equipment very large and bulky. 译：第一代电子计算机使用真空管和其他元件，这使得设备又大又笨。（增加表示复数的词） Oxidation will make iron and steel rusty. 译：氧化作用会使钢铁生锈。（增加具有动作意义的抽象名词） The cost of such a

转译成汉语副词。,由于英汉两种语言属于不同的语系，所以它们在语言结构与表达形式方面各有特点。要使译文既忠实于原意，又顺畅可读，就不能局限于逐词对等，必须采用适当的词性转换。,转译成汉语动词,A change of state from a solid to a liquid form requires heat energy. 译：从固态变为液态需要热能。（名词转译成动词） The term
