in stylistics),(4),逻辑性强，连词多,(Strict in Logic),(5),专业术语多，表达各专业不同,(Concentrated in Technical Terms),1,，无人称,It,句型大量使用,Reading is a very important language skill for foreign language learners.The significance of language learning strategies in reading comprehension is self-evident.,2,，语气正式,概念准确,名词多,1)Although the majority of tunnel construction projects have been completed safely,there have been several incidents in various tunneling projects that have resulted in delays,cost overruns,and in a few cases more significant consequences such as injury and loss of life.,2)TheWorld Health Organization estimates that fine particulate air pollution(PM 2.5)causes about 3%of mortality from cardiopulmonary disease,about 5%of mortality from cancer of the trachea,bronchus,and lung,and about

have investigated/This paper illustrates,等句式。,（,2,）英语科技文章名词化结构用得多。,（,3,）时态变化不明显：汉语里的动词无时态变化。英语中叙述客观事实几乎千篇一律使用现在时。,（,4,）在语态方面，汉语中主动语态使用较多，而英语中，被动语态使用较多。,（,5,）汉语和英语的科技文章中，句子结构都较为复杂。,科技汉译英的方法,1),名词化结构,2),被动语态的应用,3),运用特殊句型和长句,1),名词化,(Nominalization),广泛使用能表示动作或状态的抽象名词,“,Scientific writing differs greatly from the other styles in having a highly proportion of noun phrases with complexity,”,(Quirk),阿基米德最先发现,固体排水,的原理。,Archimedis first discovered the principle of,displacement of water by solid bodies,.,比较：,Archimedis first discovered the principle that solid bodies,could displace water,.,合同双方令人满意地,履行合同义务,是拓展业务和扩大合作的前提。,A)That both parties,fulfilled the Contract satisfactorily,will be the basis for the development of business and further cooperation.,B)The,satisfactory fulfillment of the Contract,by both parties will be the basis for the development of business and further cooperation.,名词连用（“扩展的名词前置修饰语”,Expanded Noun Premodifiers,）,可以有效地简化语言结构。,Illumination intensity determination=determination of the intensity of illumination,照明强度测定,Power transmission relay system=a relay system for power transmission,送电中继体系,2),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。因此尽量使用第三人称叙述，采用被动语态。,科技英语常用句型及翻译定式,1,It is supposed that,2,It is reported that,3,It can be clearly seen that,4,It should be noted that,5,It may be safely said that,6,It must be stressed that,7,It has been proved that,8,It was estimated that,9,It will be seen from this that,10,It is generally considered that,本文简要定性地讨论,了一些基本概念。,A brief qualitative discussion,of some basic concepts,is presented,in this paper.,cf,.This paper gives/presents a,brief qualitative discussion,of some basic concepts.,回指释义策略在英语阅读理解中解释功能的研究,【Abstract】This case study aimed to explore the use of anaphora resolution strategy in English reading comprehension.Three research questions,were addressed,as follows:(1)What obstacles do readers meet in English reading comprehension?(2)What is the relationship between anaphora resolution and English reading comprehension?(3)How does anaphora resolution strategy training promote readers English reading comprehension?,3),运用特殊句型和长句,科技文章中经常使用若干特定的句型，从而形成科技文体区别于其他文体的标志。,1)Itthat,句型；,2),其他固定结构：定义，比较,分类,显然，润滑好的轴承，比不润滑的轴承容易转动。,It is evident that,a well lubricated bearing turns more easily than a dry

corrosion.,大型变压器的效率可以,高达,99%.,Large transformers can achieve efficiencies of,as much as,99%.,长句,为了表述一个复杂概念，使之逻辑严密，结构紧凑，科技文章中往往出现许多长句。有的长句多达七八十个词，以下即是一例。,The efforts,that,have been made to explain optical phenomena by means of the hypothesis of a medium,having,the same,physical character,as,an elastic solid body,led,in the first instance,to,the understanding of a concrete example of a medium,which,can transmit transverse vibrations,and at a later stage,to,the definite conclusionthat,there is no luminiferous medium,having,the physical character assumed in the hypothesis.,为了解释光学现象，人们曾试图假定有一种具有与弹性固体相同的物理性质的介质。这种尝试的结果，最初曾使人们以为有一种能传输横向振动的具体介质,后来人们得出结论认为所假设的那种物理性质的发光介质并不存在。,不言而喻，本保函自开立之日起生效，开标之日起,60,天后失效。如果投标方及你方都同意延期，则在通知担保人的前提下，本保函在延长的有效期内依然有效，除非你方提前终止或解除本保函。,It
