翻译技巧第九节被动语态的译法英汉对比研究表明，英语中被动语态的使用极为普遍，尤其是以科技英语为主。

这是英语区别于汉语的显著特点之一。

在英语中，大凡为了强调受事，以突出其鲜明位置，而无需提及主动者、无意点明主动者、无从说出主动者，为了上下文的衔接与连贯等等，或是出于礼貌措辞圆通等方面的考虑不愿说出动作的执行者是谁的，往往都采用被动语态。

例如：(1)When will we be interviewed?我们什么时候来参加面试呢?(2)New British and American films are often shown to English major juniors.常给英语专业的三年级的同学放映新的英美电影。

(3)The happy man cannot be harried.吉人自有天相。

(4)You are cordially invited to a dinner party to be given at the Workers’ Club in Xidan at 7 P. m.Nov. 23.谨定于11月23日晚上7时在西单工人俱乐部举行晚宴，敬请光临。

(5)The plan was especially supported by those who wished to have more chance to speak French. 这个计划特别受到愿多有机会说法语的人的支持。

在英语中，被动结构能给人以间接、客观的印象，因而在科技文献、政论文和新闻报道等文体中使用尤为频繁。

相比之下，被动语句在汉语中的使用范围小得多。

主要原因在于，在历史上，汉语被动语句主要用来表达对主语来说是如意或不希望发生的事情。

现代汉语的这种限制虽然在西方语言的影响下有所动，被动句式有时也用来表达中性甚至希冀之事，但是汉语采用的主要是语义型句式，大多数被动意义并不一定非得通过被动语句来表达，而可以通过形式上主动、语义上被动的句式予以体现。

科技英语中的专业术语翻译
1.意译：根据科技术语的含义，将其翻译成汉语里和他完全对等的名词就叫意译。

对单个
词语来说，它能使读者了解真正的含义。

例如：
①firewall 防火墙
②data mining 数据挖掘
③automatic program control 自动程序控制
2.音译：根据英语的发音翻译成汉语里相应的词语。

科技英语中某些由专有名词构成的术
语、单位名称等，可采用音译法。

例如:
●gene 基因quark 夸克
●nylon 尼龙
●Hertz 赫兹
3.形译：英语中优秀科技术语在翻译是可以保留一部分，或保留原字母。

这就是形译。

I-bar
工字钢、工字笔；O-ring 环形圈；α-brass α黄铜【1】
4.缩习词：用英语首字母代替，干脆不译。

例如：
⊙CPU:中央处理器
⊙ASCII:美国信息交换标准码
一些国际组织的缩写也采用这种方法。

例如：
WTO(世界贸易组织)
注[1]：指含锌量≤35%的铜锌合金。

it Four我国在世界上的竞争力很高兴有机会为贵校系列经济研讨会举行开幕式，因为我认为，在经济飞速变化的当今时代，教育界起着至关重要的作用。

我国的企业和工人面临一系列强大力量，这些力量将影响今后我国在世界上的竞争能力。

成功地使工人和管理人员做好准备，驾驭这些力量，将是决定结果的一个重要因素。

其中最核心的力量，是计算机和电信技术的加速发展。

人们有理由地期望，这种发展将使我们在21世纪的生活水平显著提高。

但是，在短期内，飞速的科技变革产生这样一种情况，其中多数管理人员与工人借以工作的工厂和设备的更迭速度加快，给人这样一种感觉，即人的技能正以美国历史上前所未有的速度老化过时。

我将设法把这一极不寻常的现象放在我国经济大变革的背景下来探讨，并希望说明，教育，尤其是提高高级技能，对今后我国经济的增长为何如此重要。

几乎可以肯定，财富的创造都是伴随着人们利用日益增长的知识和不断增长的资本，生产出有价值的商品和服务。

借助各种市场价格，企业家们竭力弄清那些人们看重的各类产品和服务。

一个世纪之前，至少我们许多的努力是用于生产衣食住行方面的产品。

只有当农作物产量提高，蒸汽动力得以开发，纺织业效率提高时，现有的工作时间才能腾出来进行提供和消费选择性较大的商品和服务。

我们制造汽车和冰箱，学会如何用越来越少的投入生产这些产品。

随着这些商品进入大多数家庭，人们转而将精力用于创造较少受体积限制的高价值商品，如体积较小的晶体管电器，并进而提供各种无形服务——医疗、教育、娱乐和旅行等。

对每种商品或服务的各种特性分类定价，有助于其对每个人产生最大价值的价值最大化。

努力扩大选择，以满足个人的特定需求，必将导致从比较直接地利用物质资源和劳动力，转变为利用思想和概念——或更笼统地说利用信息——去创造价值。

因此，毫不奇怪，在过去这个世纪中，美国实物实际国内总产值的最大一部分增长，归因于新的见解，更宽泛地说，归因于新的知识—如何重新安排客观物质，以实现更高的生活水平。

1 Monograph专著1. The general definition of a monographScientific treatises of book length but otherwise variable format prepared by acknowledged experts onspecialized topics for the benefit of others who have specialized in. or who wish to obtain a specialist'sappreciation of, these topics.2. The value of monographs for scientific researchesThe value of monographs lies in the coherence and comprehensiveness of the information and knowledge theycontain, which is important to the specialized researchers to whom they are directed and, therefore, to theadvancement of science and engineering generally.3. The qualities of the authors of monographsThe authors of monographs should have exceptional breadth and depth of knowledge, and must be able tocollect, collate, analyze, integrate, and synthesize all relevant contributions to the archival literature of thescientific and engineering journals and to add original material as required.4. The differences between monographs and books of conference proceedingsMonographs generally are written by specialists for the benefit of other specialists. Textbooks are pedagogicalworks which, even if written on fairly narrow subjects, are designed to serve broader and more juniorreaderships than specialized research communities.5. The differences between monographs and books of conference proceedingsConference papers commonly take the form of premature announcements of new scientific discoveries.Conference proceedings generally have a short shelf life.6. The main components of a monographThe author, title and subtitle, date of publication, dust cover or blurb, content pages, bibliography and index,illustrations, preface and introduction.7. An indication of the book’s successThe number of editions is an indic ation of the book’s success.8. The function of the blurbIt gives the reader a rapid overview of the contents and approach. It might also say what the book contains andfor whom it is written.2 Academic Journal学术期刊1. The general definition of an academic journalAn academic journal is a peer-reviewed periodical in which scholarship relating to a particular academicdiscipline is published.2. The significance of peer-review processThe peer-review process is considered critical to establishing a reliable body of research and knowledge.3. The definition of review articlesReview articles, also called “reviews of progress”, are checks on the research published in journals.4. One difference between original research articles and review articlesUnlike original research articles, review articles tend to be solicited submissions, sometimes planned years inadvance.5. The places where science journals are authoritatively rankedNatural science journals are categorized and ranked in the Science Citation Index, and social science journalsin the Social Science Citation Index.6. The possible quantitative factors to reflect an academic journal’s prestigeThe number of later articles citing articles already published in the journal, the overall number of citations,how quickly articles are cited, and the average “half-life” of articles.7. The financial resources of humanities and social science academic journalsSubsidies by universities or professional organizations and advertising fees by advertisers.8. The role of internet in the production of, and access to, academic journalsThe Internet has revolutionized the production of, and access to, academic journals, with their contentsavailable online via services subscribed to by academic libraries or even in a way of open access. 33 Organization of a Scientific Paper科技论文的篇章结构1. In most scientific journals, scientific papers include the following sectionsSummary or Abstract, Introduction, Materials and Methods, Results, Discussion, Acknowledgments.2. The content of Summary or AbstractIt gives a brief background to the topic, describes concisely the major findings of the paper, and relates thesefindings to the field of study.3. The Introduction section deals with the following two pointsIt describes first the accepted state of knowledge in a specialized field; then it focuses more specifically on aparticular aspect, usually describing a finding or set of findings that led directly to the work described in thepaper.4. The purpose of Materials and MethodsIts purpose is to describe the materials used in the experiments and the methods by which the experimentswere carried out.5. The two ways of organizing ResultsIn some papers, the results are presented without extensive discussion, which is reserved for thefollowingsection. In other papers, results are given, and then they are interpreted, perhaps taken together with otherfindings not in the paper, so as to give the logical basis for later experiments.6. The purposes of the Discussion sectionThe data in the paper are interpreted; the findings of the paper are related to other findings in the field; thisserves to show how the findings contribute to knowledge, or correct the errors of previous work; some of thelogical arguments are often provided when it is necessary to clarify why later experiments were earned out.7. The reason for combining the Results and DiscussionBecause the data need extensive discussion to allow the reader to follow the train of logic developed in thecourse of the research.8. The difference between the abstracts in Science and those in NatureIn Science, the abstract is self-contained; in Nature, the abstract also serves as a brief introduction to the paper.4 Reading a Scientific Paper科技论文的阅读方法1. The order to understand the major points of the work, you should first readThe Abstract.2. Reading the Title and the Abstract serves three purposesFirst, it clarifies whether you in fact know enough background to appreciate the paper. Second, it refreshesyour memory about the topic. Third, it helps you integrate the new information into your previous knowledgeabout the topic.3. When reading in a familiar field, you can skim or even skipThe Introduction.4. The three typical codewordsData not shown, unpublished data, preliminary data.5. The poorly written papers are often related to three types of writersThose who are poor writers; those who do not enjoy writing, and do not take the time or effort to ensure thatthe prose is dear and logical; those who are so familiar with the material that it is difficult to step back and seeit from the point of view of a reader not familiar with the topic.6. The three characteristics of “bad writing”First, the logical connections are often left out. Second, papers are often cluttered with a great deal of jargon.Third, the authors often do not provide a clear roadmap through the paper.7. In better writing, the side issues are dealt with in the following waysThey are relegated to Figure legends or Materials and Methods or clearly identified as side issues, so as not todistract the reader.8. Another problem faced by the readers is that when they seek to understand just the experiment was,they may findThe authors refer back to previous papers; these refer in turn to previous papers m a long chain.。

produced machine tools to which precision instruments were attached.[E.141]166.Good clocks have pendulums,which are automatically compensated for temperature changes.[E.142]167.Gases,the molecules of which are widely separated from one another,have greatcompressibility than liquids.[E.143]168.An improved design of such a large tower must be achieved which results in moreuniformed temperature distribution in it.[E.155]169.A body that contains only atoms with the same general properties is called anelement.[E.156]170.Such liquid fuel rockets as are now being used for space research have to carry theirown supply of oxygen.[E.157]171.Such propellers as we have recently designed for small ships are actually modeledon fish tails.[E.158]172.Many inventors followed the same principles as that French inventor had used in hisInvention.[E.159]173.A color transmission contains the same information as a black and whitetransmission.[E.160]174.Were there no transformers to adjust the voltage,long-distance transmission ofelectricity would be impossible.[E.184]175.Should there be urgent situations,press this red button to switch offelectricity.[E.185]176.The temperature at the sun's center is as high as 10,000,0000C.[E.186]177.The outer portion of the wheel may travel as fast as 600miles per hour.[E.187]178.The oxygen atom is nearly 16times heavier than the hydrogen atom.[E.188]179.Mercury weighs more than water by about 14times.[E.189]180.Solar cells are as different from so called solar heating panels as solid state physicsis from plumbing.[E.190]181.In such occasions we would rather increase the friction of the surface than deceaseit.[E.191]182.The loads which a structure is subjected to are divided into dead loads,thewhichinclude the weights of parts of the structure,and live loads.Which are due to the weights of people,movable equipment,etc.[E.245]183.The resistance of any length of a conducting wire is easily measured by finding the potential difference in volts between its ends when a known current is following.[E.246]184.Fuel cells are devices that when a fuel such as hydrogen or hydrogen-rich compounds and oxygen is supplied to materials arranged like the anode and cathode of a conventional battery,combine to convert chemical energy directly into electrical energy.[E.247]185.With the same number of protons,all nuclei of a given element may have different numbers of neutrons.[E.248]186.The unit of electrical energy is called the joule,which is equivalent to10exp(7) ergs.[E.249]187.The discovery that electrical currents can be produced by magnetism is extremely important in the field of electricity.[E.250]188.Grounding every circuit,however,makes the system susceptible to excessive currents should a short circuit develop between a live conductor and ground.[E.251]189.It is very interesting to note the differently chosen operating mechanism by the different manufacturers,in spite of fact that the operating mechanism has a major influence on the reliability of the circuit-breakers.[E.252]190.The construction of such a satellite is now believed to be quite realizable,its realization being supported with all the achievements of contemporary science,which have brought into being not only materials capable of withstanding severe stresses involved and high temperatures developed,but new technological processes as well.[E.253]191.Various machine parts can be washed very clean and will be as clean as new ones when they are treated by ultrasonic waves no matter how dirty and irregularlyshaped they may be.[E.254]CHAPTER SEVEN192.Theγ-rays are not affected by an electric field.[E.4]193.If the work piece is gabbed directly,it warps due to the body temperature.[E.5]194.If a body is acted on by a number of forces and still remains stationary,the body is said to be in equilibrium.[E.6]195.An oxidation number may be assigned to each atom in a substance by the application of simple rules.[E.7]196.The second group is composed of compounds derived from or related to benzene C6H6.[E.8]197.The crops were washed away by the flood.[E.9]198.The airplane is supported by the wings;it is propelled by the power plant;it is guided by its control surfaces.[E.10]199.This extraction rate was confirmed in batch tank tests.[E.11]200.Other advantages of our invention will be discussed in the following.[E.12]201.These problems must be solved before the test starts.[E.13]202.North China was hit by an unexpected heavy rain,which caused severe flooding.[E.14]203.The hypothesis was not accepted by most chemists until the1970s.[E.15]204.The first car driven by one of these engines was seen on the roads in1894.[E.16]。
