翻译技巧之拆分法（division）和合并法（combination）拆分法和合并法：这是两种相对应的翻译方法。
拆句法是把一个长而复杂的句子拆译成若干个较短、较简单的句子，通常用于英译汉；合并法是把若干个短句合并成一个长句，一般用于汉译英。
汉语强调意合，结构较松散，因此简单句较多；英语强调形合，结构较严密，因此长句较多。
所以汉译英时要根据需要注意利用连词、分词、介词、不定式、定语从句、独立结构等把汉语短句连成长句；而英译汉时又常常要在原句的关系代词、关系副词、主谓连接处、并列或转折连接处、后续成分与主体的连接处，以及意群结束处将长句切断，译成汉语分句。
这样就可以基本保留英语语序，顺译全句，顺应现代汉语长短句相替、单复句相间的句法修辞原则。
如：（1）Increased cooperation with China is in the interests of the United States.同中国加强合作，符合美国的利益（在主谓连接处拆译）（2）I wish to thank you for the incomparable hospitality for which the Chinese people are justly famous throughout the world.我要感谢你们无与伦比的盛情款待。
中国人民正是以这种热情好客而闻明世界的。
（在定语从句前拆译）（3）This is particularly true of the countries of the commonwealth，who see Britain‘s membership of the Community a guarantee that the policies of the community will take their interests into account.英联邦各国尤其如此，它们认为英国加入欧共体，将能保证欧共体的政策照顾到它们的利益。
（在定语从句前拆译）实例分析一、英译汉中的拆分译法：常包括单词分译、短语分译和句子分译等三种情况。
（一）单词分译单词分译是指把原文中的一个单词拆译成一个小句或者句子。
采用单词分译主要有两个目的：一是为了句法上的需要。
由于一些单词在搭配、词义等方面的特点，直译会使句子生硬晦涩，翻译腔十足，而把某个单词分译却能使句子通顺，且不损伤原意。
二是为了修饰上的需要，如加强语气，突出重点等。
英语中的名词、动词、形容词和副词等都可分译。
例如：We recognize that China's long-term modernization program understandably and necessarily emphasizes economic growth.我们认识到，中国的长期现代化计划以发展经济为重点，这是可以理解的，也是必要的。
(副词拆分)Then and there he named the startled General lying wounded on his cot the new Commander in Chief of the Airforce.他就在当时当地任命这位躺在榻上治伤的将军为空军总司令，使这位将军吃了一惊。
（拆分过去分词）A movie of me leaving that foxhole would look like a shell leaving a rifle.我离开那个猫儿洞的速度之快，要是拍成电影的话，会象出膛的子弹一样。
（拆分名词）Yet it is painfully apparent that millions of Americans who would never think of themselves as law-breakers, let alone criminals, are taking increasing liberties with the legal codes that are designed to protect and nourish their society.显然，数百万美国人从来没有想过自己会违法，更不用说犯罪了，而就是他们正在越来越肆意歪曲旨在保护和培育这个社会的法律条文，这真令人痛心。
（原文中painfully apparent如照字面译成"痛心地明显的"，不合汉语表达习惯，将painfully单译成句，既突出了重点，表明作者对这一现象感到痛心的心情，又使语言自然流畅。
）At present people have a tendency to choose the safety of the middle-ground reply.现在，人们都倾向于采取不偏不倚的态度来回答问题，因为它安全，不招风险。
（choose the safety of the middle-ground reply如机械直译成"选择不偏不倚回答问题的安全"，语言晦涩难懂。
将safety分译出来则较好地解决了这一问题。
）Auntie Julia vainly asked each of her neighbours in turn to tell her what Gabriel had said.朱利亚姨妈接连向坐在旁边的人打听加布里埃尔刚才说了些什么，却没有问出个所以然来。

短语拆分：短语分译是指把原文中的一个短语分译成一个句子。
名词短语、分词短语、介词短语等有时都可以分译成句。
例如：（1） These cheerful little trams, dating back to 1873, chug and sway up the towering hills with bells ringing and people hanging from every opening.这些令人欢快的小缆车建于1873年，嘎嚓嘎嚓摇摆爬上高耸的山峦。
