同声传译在翻译公司很常见，适用于大型的研讨会和国际会议，是由译员在不打断演讲者讲话的情况下不间断的将内容口译给听众的翻译方式。

　　In the case of large-scale conference without interruption, it is very common for the interpreter to interpret the contents of the conference without interruption.

　　同声传译是一门艺术。要掌握好这门艺术，就需要在实践中认真研究翻译的方法和技巧。翻译没有现成的公式可套,它是千变万化的,一个句子可以有多种不同的表达方法。译员要在实践中不断摸索、不断总结，才能逐步提高翻译水平。无论英译汉还是汉译英，都涉及英语和汉语两种语言。这两种语言是两种截然不同的文化的产物。虽然它们有共性，但在语法、句型、习惯用语、修辞手段、逻辑等许多方面都各有特点。英语重形合，靠连接词表明逻辑关系;而汉语重意合，语言内部逻辑、词与词的关系靠词序就可表示出来;英语有冠词、代名词及词形变化等，汉语没有;英、汉语有些词的词义不完全相等;英语中为使句子简洁明了，经常使用代词，或干脆省略重复的词，但在译成汉语时，常常需要重复，以使语言通顺。 译员必须在分析这些特点和差异的基础上研究翻译方法和技巧。

　　Simultaneous interpretation is an art. In order to master this art, it is necessary to study translation methods and techniques in practice. There is no ready-made formula for translation. It is changeable. A sentence can be expressed in many different ways. In order to improve the level of translation, translators should constantly explore and summarize in practice. No matter English to Chinese or Chinese to English, both English and Chinese are involved. These two languages are the product of two different cultures. Although they have common features, they have their own characteristics in grammar, sentence pattern, idiomatic expressions, rhetorical devices, logic and so on. In English, hypotaxis is emphasized and logical relations are indicated by connectives; while in Chinese parataxis is emphasized, the internal logic of language and the relationship between words can be expressed by word order; there are articles, pronouns and morphological changes in English, but not in Chinese; the meanings of some words in English and Chinese are not completely equal; In order to make sentences concise and clear, pronouns are often used or repeated words are omitted. However, when translated into Chinese, repetition is often needed to make the language smooth. Translators must study translation methods and techniques on the basis of analyzing these characteristics and differences.

　　翻译要求忠实于原文，这是指精神上或实质内容上忠实于原文。它不是要求机械地、一字对一词地翻译。翻译实际上是一种语际转换过程。在两种不同的语言之间进行语言转换时，一一对应的现象一般不多，常常需要改变语言形式。而语言形式的改变可能会造成语义、语气上的损失。 同时，在翻译时，为弥补损失，补足语气，连接上下文，有时需要增加词句，以忠实通顺地表达原文的内容，便于读者理解。此外，双关语、复数意义、时态意义、强调意义等都需要在翻译时加以补充，才能将意思完整地表达出来。 一些翻译家认为:“翻译的主要方法是该增词时增词，该减词时减词。”何时需要增减，主要标准是使译文符合习惯用法，通顺明白。这种增词、补词的方法，称为“补充法”。

　　Translation requires faithfulness to the original text, which means to be faithful to the original in spirit or substance. It does not require mechanical, word for word translation. Translation is actually a process of interlingual transformation. In the process of language conversion between two different languages, the phenomenon of one-to-one correspondence is generally rare, and it is often necessary to change the language form. The change of language form may result in the loss of semantics and mood. At the same time, in order to make up for the loss, supplement the mood and connect the context, sometimes it is necessary to add words and sentences to express the content of the original text faithfully and smoothly for the readers to understand. In addition, pun, plural meaning, tense meaning and emphasis meaning need to be supplemented in translation in order to express the meaning completely. Some translators believe that "the main method of translation is to add words when adding words, and to reduce words when reducing words." When it needs to be added or deleted, the main criterion is to make the translation conform to the idiomatic usage, smooth and clear. This method of adding and supplementing words is called "supplementary method".
