翻译是各民族思想交流的工具。不同的民族使用不同的语言,为了达到相互交流的目的,就需要通过翻译。
翻译技巧(一) 词义引申
词义引申是指改变原文字面意义的翻译方法。词义引申时,往往可以从词义转译、词义具体化、词义抽象化和词的搭配四个方面来考虑。
1. 词义转译
翻译时,遇到一些无法直译或不宜直译的词或词组,应根据上下文和逻辑关系,引伸转译。
Like any precision machine, the lathe requires careful treatment.
Solar energy seems to offer more hope than any other source of energy.
2. 词义具体化
翻译时,根据汉语的表达习惯,把原文中某些词义较笼统的词引伸为词义较具体的词。以动词 cut(切割)为例:
The purpose of a driller is to cut holes .
A single-point cutting tool is to cut threads on engine lathes.
Hard metals can be easily cut with grinding wheels。
The milling machine is often employed to cut spur and helical gears。
3. 词义抽象化
把原文中词义较具体的词引申为词义较抽象词,或把词义较形象的词引申为词义较一般的词。

From the evaporation of water people know that liquids can turn into gases under certain condition。
The major problem in fabrication (制造) is the control of contamination and foreign materials
2. 在形容词前加名词
Piston engines are used for relatively slow planes flying at 20,000 feet or less.
A new kind of aircraft-small,cheap,pilotless-is attracting increasing attention。
3. 增加起语气连贯作用的词
Hydrogen is the simplest substance, atoms of other elements having a plex structure.
The sun warms the earth, which makes it possible for plant to grown.
4. 增加概括词
