石家庄翻译公司英语翻译窍门之不译：不译或省掉翻译是在切当表达原文内容的前提下使译文简练，符合汉语标准，决不是恣意省掉某些介词。 

     (1)表明时间或地址的英语介词，译成汉语如出现在句首，大都不译。如：There are four seasons in a year. 一年有四季。 Many water power stations have been built in the country．中国已建成很多水电站。   　　 

    (2)有些介词如for（为了），from（从……），to（对……），on（在……时）等，能够不译。如：The barometer is a good instrument for measuring air pressure．气压计是丈量气压的好仪器。The air was removed from between the two pipes．两根管子之间的空气现已抽出。

 　　Answers to questions 2 and 3 may be obtained in the laboratory．疑问2和3的答案能够在试验室里得到。Most substances expand on heating and contract on cooling．大多数物质热胀冷缩。   　　 

    (3)石家庄翻译表明与主语有关的某一方面、规模或内容的介词有时不译，可把介词的宾语译成汉语主语。如：Something has gone wrong with the engine．这台发动机出了缺点。Gold is similar in color to brass金子的色彩和黄铜类似。Its never occurred to me that bats are really guided by their ears．我从未想到蝙蝠居然是靠耳朵引路的。   　　 

     (4)不少of介词短语在句中作定语。其间of（……的）通常不译。如：The change of electrical energy into mechanical energy is done in motors．电能变为机械能是经过电动机完成的。 （of短语和change在逻辑上有主谓联系，可译建立谓构造。）Some of the properties of cathode rays listed below．现将阴极射线的一些特性开列如下。（第一个of短语和some在逻辑上有有些联系，Of不译出。）
