20、备忘录将于2014年6月签定。,2023/11/7,2.2.2 谓语的转换,在翻译中，英语句子的谓语一般无须特殊处理，只是在某些情况下，英语句子的谓语可以转换为汉语的主语、定语及状语等。A sketch serves to express ones idea graphically.The sun produces in three days more heat than all earth fuels could ever produce.For the first time in the annals of space,a piloted ship had succeeded in lau

25、可少的词。3.1 复数名词汉译引起的增译。增译表示复数的汉语词，如：“许多”、“若干”、“一些”、“一批”、“有些”、“各”、“诸”等。特别是当原文中的复数具 有不可忽视的意义，若不译出就会造成误解 或语义不全时，更应如此。,2023/11/7,After a series of experiments important phenomena have been ascertained.You must know the properties of the instrument before you use it.The first electronic computers went into

27、、“作用”、“过程”、“现象”、“效应”、“装置”、“设计”、“强度”或“变化”等措辞。如：Solution to the heating problem of the electric machine was ultimately found.To get an idea of electrical pressure,let us consider a simple analogy.,2023/11/7,From the view point of conductivity,aluminum is a good material to be used for electric wires.T

28、he computations are so complicated that it would take one electronic computer several hours to work them out.From the evaporation of water people know that liquid can turn into gases under certain conditions.The magnetization of this metal is being tested.,2023/11/7,终于找到了电机发热问题的解决方法。为了得出电压 的概念，让我们考虑

29、一个简单的类似情况。从导电性的观点看，铝是做导线的好材料。这些计算过程是如此复杂，就是用计算机也得花上几个小时方能算完。从水的蒸发现象，人们得知液体在一定的条件下能转化为气体。正在测试这种金属的磁化强度。,2023/11/7,3.3 添加量词引起的增译 英语是一种缺乏量词的语言，而汉语则拥有丰富多彩的量词。因此，汉译数词时往往要添加适当的量词，这样才能使译文符合汉语的规范。A vector can be resolved into two or more other vectors whose sum is equal to the original vector.Upon gaining t

30、wo electrons the alpha particle becomes a helium atom.There stands a high building by the river.,2023/11/7,一个矢量可分解为两个或两个以上的不同矢量，这些矢量的和等于原矢量。粒子 获得两个电子之后就变成了氦原子。河边屹立着一幢高大的建筑物。,2023/11/7,3.4 翻译省略成分而一起的增译（1）翻译为避免重复而出现的省略成分时的增译英语最忌讳重复，凡前面出现的部分一般后面便不再出现，以避免重复。但汉译时往往需将其增补上，这样才能使汉语语句完整。Like charges repel ea

31、ch other,but opposite charges attract(each other).As we know,all matter consists of molecules,and molecules(consists)of atom.The letter I stands for the current in amperes,E(stands for)the electromotive force in volts,and R(stands for)the resistance in ohms.,2023/11/7,同性电荷相互排斥，异性电荷相互吸引。众所周知，一切物质由分子组

32、成，而分子由原子组成。字母I 代表电流（单位为安培），E 代表电动势（单位为伏特），R 代表电阻（单位为欧姆）。,2023/11/7,（2）翻译由于英语语法规则而出现的省略成分时的增译We suggest that the test(should)be done by 12 oclock.This conclusion proved(to be)correct.This seems(to be)an important point.,2023/11/7,我们建议这项实验应在12点前做完。这一结论原来是正确的。看来这是很重要的一点。,2023/11/7,3.5 添加关联词引起的增译 Other

34、2023/11/7,3.6 添加表示时态的词引起的增译The solution is about to boil.This electric generator has been working for several hours.By three oclock this afternoon,the fuel in the furnace will have burned up.,2023/11/7,溶液马上就要沸腾了。这台发电机已运行了几个小时。到今天下午三点，炉内燃料将烧尽。,2023/11/7,3.7 添加概括性或分述性词语引起的增译英语中在列举事实时很少用概括性的词语，在分述事物时也很

35、少用分述性的词语，但汉语则恰恰相反。因此，汉译时需根据情况增加一些概括性或分述性词语。The chief effects of electric currents are the magnetic,heating,and chemical effects.There are three basic ways of producing or storing electricity:by generator,by battery,or by accumulator.,2023/11/7,电流的效应有磁效应、热效应和化学效应三种。电的生产和储存基本方法有三种：一种是用发电机，一种是用电池，一种是用蓄

36、电池。,2023/11/7,3.8 汉译被动语态引起的增译英汉翻译中，有时会将被动语态译成主动语态。这时原文中没有出现的行为主体便会在译文中出现，因而也就引起增译。Electronics is based upon an understanding of physical world.Rubber is found a good material for the insulation of cable.,2023/11/7,电子学是以人们对物质世界的认识为基础的。人们发现橡胶是一种用于电缆绝缘的理想材料。,2023/11/7,3.9汉译祈使句引起的增译 英语的祈使句具有“命令”、“请求”或“叮

37、咛”等含义，因此汉译时应视不同情况添加“请”、“要”、“应”、“须”、“试”、“千万”、“一定”、“务必”等词语。When the machine is in operation,do keep away from it.Name five different kinds of matter.Calculate the unknowns in the following.,2023/11/7,机器在运行时，千万不能靠近。请列举五种不同的物质。试求以下未知数。,3.10 汉译某些动名词引起的增译英语中的动名词是由动词变形而来，但其动作性已高度抽象化了。在汉译成具体动作时，应相应增译某些表达具体动

38、作的动词。Dimensioning is a complicated work and long experiences are required for the mastering of it.Testing is a complicated problem,so be careful.,2023/11/7,进行尺寸标注是一项复杂的工作，需要有长期经验才能完成。进行测试是一个复杂的问题，因此，务必格外小心。,2023/11/7,3.11 汉译时为再现某些词引起的增译This magnetic field may be that of a bar magnet,U-shaped magnet,

39、or an electromagnet.We call this field of force the electric,or electrostatic field.Changing the number of turns of coils may step up or step down the voltage.The wiring of portable appliances,such as electric fires,irons,or kettles,needs particular care.,2023/11/7,该磁场可以是一根条形磁铁的磁场，可以是马蹄型磁铁的磁场，也可以是电磁

40、铁的磁场。我们称这种力场为电场，或静电场。改变线圈匝数可升压、也可降压。便携式电器，如电炉、电熨斗、电热水壶的布线要格外小心。,2023/11/7,3.12 添加某些解释性词语引起的增译We will go there by a Benz.Yesterday he bought a Sumsung.,2023/11/7,我们将乘奔驰车去那。昨天他买了一台三星手机。,2023/11/7,第四章 省译法,英语有些词，如冠词、介词、连词和代词，在汉语中要么没有必要，要么用得不多，主要是因为汉语可以借助词序来表达逻辑关系。因此，英汉翻译中的词量减少主要出现在英语冠词、介词、代词、连词及“it”在某些句

41、型中的 省译。另外，英语的谓语动词有时也可省译，因为汉语不一定要用动词做谓语，可直接用形容词、名词、偏正词组、主谓词组等作谓语。英语系动词的省译更为常见。总之，科技英语翻译中，省译法用得比增译法更多些。,2023/11/7,A salt results when a metal takes the place of the hydrogen in an acid.Hydrogen is the lightest element with an atomic weight of 1.008.A wire lengthens while it is heated.Practically all s

42、ubstances expand when heated and contract when cooled.,2023/11/7,It was no until the middle of the 19th century that the blast furnace came into use.This formula makes it easy to determine the wavelength of sounds.When the pressure gets low,the boiling point becomes low.For this reason television si

43、gnals have a short range.,2023/11/7,当酸中的氢被金属取代之后，就生成盐。氢是最轻的元素，原子量为1.008.金属丝受热则伸长。几乎所有的物质都是热胀冷缩。,2023/11/7,直到十九世纪中叶，鼓风炉才开始使用。这一公式使得确定声音的波长十分容易。气压低，沸点就低。因此，电视信号的传播距离很短。,2023/11/7,第五章句量的增减-分译与合译,由于英汉两种语言的表达习惯不同，常常需要把英语中只有一个主谓结构的句子译成具有两个或两个以上主谓结构的汉语句子，这就是分译；反之，就是合译。汉语一般不用长句，因此英译汉时，往往要把英语较长的句子成分或不易安排的句子成

44、分拆开来，译成汉语的分局，以使译文层次分明，合符汉语的习惯。,2023/11/7,单词的分译有的英语句子虽不长，但字对字译出的译文很别扭，读来非常拗口，这时往往可以把这个单词译成一个分句或单句。This year the estimated production of transistors is 400 million,and we can safely assume that even this tremendous number is likely to increase.He spoke with understandable pride of the invention of the

45、 instrument.,2023/11/7,As a secret training base for a new plane,it was an excellent site,its remoteness effectively masking its activity.短语的分译这种现象在英译汉中比单词分译更常见。英语中能提出来分译的短语，通常有分词短语、介词短语、动词不定式短语和名词短语。,2023/11/7,Let us have a good look at Fig.2 showing how heat makes objects expand.The weight of an o

46、bject has been found to vary from place to place on the earth.句子的分译所谓句子的分译，指的是把原文的从句译成分句，或把一个简单句拆开译成两个或两个以上的句子，以及在翻译复合句过程中增加分句或句子的数量。,2023/11/7,Two of the advantages of the transistor are its being small in size and its being able to be put close to each other without overheating.Flying is the oldes

47、t dream of man,perhaps reaching back to the days when caveman looked longingly upward at the birds flying overhead as they wearily pursued the animals on the earth beneath.,2023/11/7,今年晶体管的产量估计是4亿只。这个数字虽然已经很大，但产量可能还有增加。我们这样估计是有把握的。他谈到那种仪器的发明时很自豪，这一点是可以理解的。作为新型飞机的秘密训练基地，这地方是很理想的，它地处穷乡僻壤，特别便于有效隐蔽其活动。,

48、2023/11/7,让我们仔细看一下图2，它说明热如何使物体膨胀。已经发现，一个物体的重量在地球上因地而异。晶体管有两个优点:一是体积小，二是相互能靠近放置而不过热。飞行是人类最古老的梦想，也许要追溯到穴居人时代。那时候，当他们在地面上追捕动物累得筋疲力尽时，仰头看着在头顶上飞翔的鸟儿，无限向往。,2023/11/7,合 译 法合译法是把两个或两个以上的简单句（或并列句），或是把主从复合句或并列复合句合译成一个单句。,2023/11/7,There are always particles of dust in the air.Dust tints sunsets and pollutes c

49、ity air.The structure of the steel and the resulting properties will depend on how hot the steel gets and how quickly or slowly it is cooled.The Post Office was helpful,and Marconi applied in June 1896 for the worlds first radio patent.,2023/11/7,空气中总是有尘埃，会使夕阳染上红色，也使城市空气受到污染。钢的结构及最终特性，将视其加热程度及冷却快慢而定

50、。在英国邮局帮助下，马可尼于1896年6月申请了世界上第一项无线电专利。,2023/11/7,第六章 被动句的译法,6.1.1 译成汉语主动句的情况（1）把原主语仍译为主语。当英语被动句中的主语为无生命的名词，又不出现由介词by 引导的行为主体时，往往可译成汉语的主动句。这种把被动语态直接译成主动语态的句子，实际上是省略了“被”字的被动句。When rust is formed,a chemical change has taken place.,2023/11/7,(2)把原主语译成宾语。Friction can be reduced and the life of the machine
