1、机械工程专业英语 第二课翻译的基本方法 词义的选择Skills of Translation acceptation selection 要提高译文的质量， 使译文达到“准确”、“简练”、“通顺”这三个标准，就必须学习翻译技巧。翻译的技巧就是在翻译过程中用词造句的处理方法。如词的选择、词义的引伸、增词、减词、转换词类、改变句子结构、变更词序和改换译法等。一、词义的选择 词义的选择实际就是英语词在特定句子中的词义的判断和确定。词在特定句子中的确切含义，在很大程度上取决于上下文。也就是说，词的含义必须根据词在句子中的作用词的搭配习惯以及词的应用场合予以判断和确定。一般可从下列几个方面去判断。 翻译

2、的基本方法 词义的选择Skills of Translation acceptation selection1、根据词类判断词义英语中，有些词用作不同的词类时，其词义有时是不相同的。因此我们可根据词类来确定词义。l Every metal part is of great importance to machines.每一个金属部件对机器都是很重要的。(n)l Aluminum machines faster than other metals.铝加工起来比其它金属快。(v)l icroprocessors monitor tyre wear and brake power on cars.

3、微机检测汽车轮胎的耐用性和制动力。(v)l The patient was connected to a television wave monitor.病人的情况曾通过波形监视器监视。 (n) 翻译的基本方法 词义的选择Skills of Translation acceptation selection2、根据上下文选择词义严格说来，孤立的一个词很难确定它是什么意思，因为同一个词在不同的场合可能具有不同的意义，因此有些词必须根据上下文来确定其词义。l The countrys industry has developed quickly in the last decade. 过去十年里，

4、我国工业迅猛发展。l To develop the instrument, many experts were invited.在研制这种仪器时请了许多专家。l The function of the engine is to develop the necessary power. 发动机的功用就是产生所需要的动力。翻译的基本方法 词义的选择Skills of Translation acceptation selectionl This cooling system failed. 这个冷却系统失效了.l Newtons laws fail to describe the motion o
