1. 科技英语的语言特点概述
任何作品均有特定的文体，原文的文体不同，翻译方法也随之而异。试观察下列几个片断的原文及其译文。
"It appears that you’ve got the offer of a very good job."
"A wonderful job."
"Are you going to take it ?"
"I don’t think so."
"Why not?’
"I don’t want to."
“听说有个很好的工作要你去干。”
“挺好的工作。”
“打算干吗？”
“不。”
“为什么不干？”
“不想干。”
这是小说中的一段对说，属于口语文体。其特点是：用词自由，句法结构简单，短句与省略句多，自然朴素，生活气息浓厚。在译文中进一步体现汉语口语的特点，省去主语“你”、“我”；将英语的一个句子I don’t think so。干脆译成一个字“不”，显得简洁有力。
She was of a helpless, fleshy build, with a frank, open countenance and an innocent, diffident manner. Her eyes were large and patient, and in them dwelt such a shadow of distress as only those who have looked sympathetically into the countenances of the distraught and helpless poor know anything about.
那妇人生着一副绵软多肉的体格，一张坦率开诚的面容，一种天真羞怯的神气。一双大落落的柔顺眼睛，里边隐藏着无穷的心事，只有那些对于凄惶无告的穷苦人面目作过同情观察的人才看得出来。上面五十一个词的片断，就运用了十个形容词，占五分之一。and in then dwelt such a shadow of distress是非常优美生动的文学语言，译文保持了一风格。
Johns accomplished a spectacular debut for his NHL career tonight, the first score launching a four -point first period out burst,to lead the Johnson City High Hats to a 6:4 victory over the Montreal Teals and their eighth consecutive game without a loss.
在全国手球联赛中克拉克约翰斯今晚初试锋芒，引起轰动。上半场领先四分，首开记录。克拉克发挥中坚作用，约翰逊市高帽队终以6:4击败蒙特利尔市小鸭队，创造了连胜八场未负一场的战绩。
这是属于应用文的新闻文体，其特点是简明扼要，短小精悍，结构紧凑，笔锋犀利。上述这则电讯只有一个句子，却把一场球赛描绘得淋漓尽致，富于吸引力。
The range of a voltmeter may be extended by means of a series resistor called a multiplier as shown in Fig.2.The fullscale reading of the meter alone may be 15volts.With the multiplier 250volts may be required to move the pointer to full-scale, 135 volts across the multiplier and 15volts across the meter.
从上述的一段科技文章，不难看出其文体与修辞手段与前面列举的文艺小说，新闻报道等迥然不同。科技文体崇尚严谨周密，概念准确，逻辑性强，行文简练，重点突出，句式严整，少有变化，常用前置性陈述，即在句中将主要信息尽量前置，通过主语传递主要信息。
