1 第五章 定语从句的译法 翻译和阅读考查的重点！！

2 定语从句的译法 前置定语 和 后置定语 较简单

3 后置定语 -----位于名词或代词之后的定语 科技英语：准确性+严密性 ---频繁使用后置定语

4 作定语的情况 1、介词短语 2、形容词(或其短语) 3、非限定词（不定时、现在分词、过去分词 4、定语从句 5、同位语从句

5 1、介词短语作后置定语 In general，ethers are good solvents for fats，waxes and resins． 通常，对脂肪、蜡、树脂醚是好的溶剂。 醚通常是脂肪、蜡、树脂的良好溶剂。

6 The gas from flask is washed with water to remove ammonia.
烧瓶里出来的气体用/被水洗涤可除去氨。

7 The presence of a substituent group in benzene plays a profound control over orientation of the entering substituent． 苯中取代基的存在对进入取代基团的方位起着强有力的控制作用

8 2.形容词(或其短语)作后置定语 Acetylene is hydrocarbon especially high in heat value. 乙炔是烃，在热值上特别高 乙炔是热值特别高的烃。

9 All of the carbon-carbon bonds in benzene are alike and have properties intermediate between those of a single and a double bond． 苯中所有的碳-碳键都相似，具有介于单键和双键之间的性质。

10 Hydrocarbons that do not contain the maximum number of hydrogen atoms possible are called unsaturated hydrocarbons． 不含有最大氢原子数的烃可能叫不饱和烃。 不含有最大可能氢原子数的烃叫不饱和烃。

11 3. 不定时、现在分词、过去分词 要从时态、语态两方面辨析

12 从时态上： 现在分词-----动作正在发生 过去分词-----动作已经完成

13 从语态上： 现在分词表示的动作具有主动意义 及物动词的过去分词表示被动意义； 不及物动词的过去分词不具有被动含义，仅表示动作已经完成

14 substitute ---根据上下文决定
substituted group 若substitute为及物动词，则译为“被取代的基团” 若substitute为不及物动词，则译为“取代了的基团”，即“取代基”（表示动作已经完成） ---根据上下文决定

15 It is this metal ion that reacts with the hydrocarbon being nitrated.
就是这个金属离子与要被硝化的烃起反应。(现在分词作后置定语)

16 The air is a material containing many kinds of gases.
空气是含有许多气体的一种物质 (现在分词短语作后置定语)

17 The functional group of a ketone consists of a carbon atom connected by a double bond to an oxygen atom． 酮的官能团是由一个通过双键与氧原子相连的碳原子组成的。 (过去分词短语作后置定语)

18 4. 定语从句作后置定语 限制性定语从句 非限制性定语从句
包括 限制性定语从句 非限制性定语从句 由： 关系代词(that,which,who,whom,whose,but,as) 关系副词(where,when,why,as等)引导

19 限制性定语从句 和所修饰的名词或代词(称为先行词)之间的关系十分密切，是先行词在意义上不可缺少的修饰说明语
限制性定语从句的主句的含意是不完整的，要靠定语从句补充说明，全句概念才能表达清楚 从句与主句之间没有逗号

20 非限制性定语从句特征 主要采取分译法，作为并列分句进行翻译 和先行词之间的关系不很密切，不起限制作用，只加以补充说明
缺少了非限制性定语从旬，主句的意思仍然完整明确 定语从句与主句之间有逗号分开 主要采取分译法，作为并列分句进行翻译

21 定语从句作后置定语译法 1.翻译成定语 ---限制性 2.译成表示同等关系的并列分句 3.译成表示转折的并列分句 4.译成状语从句并列分句 5.由“as”引导的非限制性定语从句 限、非限

22 (1) 译成含“的”字定语--限定从 合译法： “的’字结构放在被修饰词之前 把定语从句和主句合译成汉语的单句 ----适合于翻译结构不很长的 (最简单、常见的译法)

23 Space and oceans are the new world that scientists are trying to explore．
太空和海洋是科学家们努力探索的新领域。

24 Of all the forms of energy that we use，electrical energy is the most convenient．

26 When fuels burn，they return once more to the simpler materials out of which they were made．
燃料燃烧时，又转变成原来构成它们的那些更加简单的物质。

27 One may already have some idea of the material with which organic chemistry deals，but he may not know the extent to which organic chemistry touches on our everyday life． 也许有人已经对有机化学所涉及的物质有所了解，但是他可能并不知道有机化学触及我们日常生活已达到什么样的程度。 dealing with – about – on -- involving

28 限制性定语从句省略了关系词，翻译时也同样采用合译法译成定语。如：
The rate at which the molecules move depends upon the energy they have． 分子运动的速率取决于分子所具有的能量。(省略了关系代词which或 that) which that

29 (2)译成表示同等关系的并列分句 定语从句起着对先行词进一步说明的作用， 往往译成并列分句，可加译“这”、该” 、“其、它、这”等词

30 An acid is a compound whose solutions can produce hydrogen ions．
酸是这样一种化合物， 其溶液能产生氢离子。

31 One of the homolog of benzene is toluene which is the raw material for the manufacture of the explosive． 苯的一个同系物是甲苯，它是制造炸药的原料。 homo- 同，相同

35 有时，可省略先行词 They worked out a new method by which production has now been rapidly increased． 他们制定出一种新方法，采用之后生产能力已迅速提高。

36 In most parts of the sea, there are millions of tiny living things that can hardly seen with our eyes． 在大部分海域里，生存着无数的微小生物，用我们的眼睛是看不见的。

37 (3) 译成表示转折的并列分句 当定语从句在意思上与主句相对照或语气转折时，可译成转折句。 加译“而、但、却、可、是” 根据上下文逻辑

38 Matter is composed of molecules that are composed of atoms that are composed of nuclear and electron. 物质是由分子组成的，而分子又是由原子组成，（而）原子又是由原子核和电子组成的。

39 Mild oxidation of a alcohol gives an aldehyde which may be further oxidized to an organic acid.
醇的轻度氧化生成醛，而醛能进一步氧化生成有机酸。

40 (4) 译成状语从句 可加译“因为、虽然、只要、因而”等词
在意义上相当于表示原因、结果、目的、条件、让步等的状语从句时 可加译“因为、虽然、只要、因而”等词

41 The problem，which is very complicated，has been solved．
这个问题虽然很复杂，但已经解决了。 这个很复杂的问题已经解决了。 (表让步)

44 (5)以as引导的限制性定语从句 值得注意 关系代词经常与such，the same…as as many, as much等配合，在从句中作主语、表语、宾语等 译法较固定

45 such+(名词)+as 或such as 译为 “象……之类的” “象……(这)那样的” “…的一种”等 例如：

46 Without rubber there would be no automobiles such as we have today．
如果没有橡胶，就不会有象我们今天这样的汽车。

47 Such liquid fuel rockets as are now being used for space research have to carry their own supply of oxygen． 象现在用于太空研究的这类液态燃料火箭，必须自己携带氧气。

48 the same…as 译为 ‘‘和……一样的” “与……相同的” 例如：

49 Many inventors followed the same principles as that French inventor had used in his invention．
许多发明家遵循那个法国发明家在他的发明中曾用过的同样原理进行发明创造。

50 例子 Social science is that branch of intellectual enquiry which seeks to study humans and their endeavors in the same reasoned, orderly, systematic, and dispassioned manner that natural scientists use for the study of natural phenomena

51 Social science is that branch of intellectual enquiry which seeks to study humans and their endeavors in the same reasoned, orderly, systematic, and dispassioned manner that natural scientists use for the study of natural phenomena. 结构：主句+ which引导的定语从句+方式状语 +定语从句 词： Intellectual：智力的, 知识的 Enquiry：询问- 探究 inquire Endeavor：奋力，努力 humans and their endeavors -- 人类及其行为 Reasoned：理性的 Orderly：有序的 Dispassioned：冷静的 Manner：方式

53 定语从句作后置定语译法总结 (1)译成“的”字定语--限制性定从 (2)译成表示同等关系的并列分句 (3)译成表示转折的并列分句 (4)译成状语从句

54 非限制性定语从句译法

55 非限制性定语从句译法 特点： 和先行词之间的关系不很密切 不起限制作用 只加以补充说明

56 非限制性定语从句译法 主要采取分译法（作为并列分句进行汉译） 定语从句多数译为并列句的一个分句 译成独立的简单句

57 非限制性定语从句三种技巧 译成并列分句，重复先行词的含义 根据全句的意义使用 指示代词“这一”、“该”、“其” 人称代词“它”、“它们”等 3. 具有转接意义时，加连词“而”、但”等

63 非限制性定语从句也可合译 从句与主句关系较密切时 较短而且有描述性含义时 即译成带“的”的前置定语

发明了电灯的托马斯·爱迪生，对科学作出了重要贡献。

65 You can break up a beam of light with a prism，which is made of glass．

66 由“as"引导的非限制性定语从句 相当于表示说话人态度和看法的插入语， 一般译成状语从句： “正如…”\“正如……那样”

67 As has been pointed out above，solids do not expand as much as gases and liquids．
正如上面所指出的，固体的膨胀没有气体和液体的那么大

68 As we know，the molecules of gas move freely in all directions．

73 同位语从句: 作后置定语 同位语从句： 说明前面的某个词（本位语）
主要由that，也用 whether / if （是否 ）引导，但没有词义，不作成份，只起连接作用

74 本位语一般有： fact, idea, theory, problem, doubt, trith, question, evidence等

75 have no idea of – do not know
同位语从句作后置定语 Have you heard any idea how fast sound travels? 你知道声音传播的有多快？ have no idea of – do not know

84 练习 There will be television chat shows hosted by robots, and cars with pollution monitors that will disable them when they offend
