专业英语

1.广泛使用被动语态 (客观性)
非人称语气
主体是客观现象及事物本身，而非动作的发出者，把论证 说明的对象置于句子主语的位置，既能突出中心，又能吸引读 者的注意。 Solid materials are grouped into three basic classifications: metals, ceramics and polymers. 固体材料可分为三种基本类型：金属、陶瓷和聚合物。 The structure of a material can be investigated on several levels. 材料的结构可以在几个层次上进行研究
精练性(conciseness)。
论文、综述、实验报告、教材、专利、说明书等
专业英语
Specialized English
（English for Special Science and Technology）
是结合各自专业的科技英语
有很强的专业性，涉及的面更加狭窄，
与专业内容配合更为密切。 隶属于科技英语 是科技英语的一部分，以表达科技概念、理论与
3、后置形容词短语作定语多 （精炼）
代替定语从句作后置定语，使句子简洁、紧凑，不至于累赘。 All radiant energies have wavelike characteristics, which are analogous to those of waves moving through water. All radiant energies have wavelike characteristics analogous to those of waves moving through water. 所有的辐射能都具有波的特性，与水中移动的波的特征相似。

句法特点

a. 大量使用名词化结构 名词化过程主要是把表达“ 过程”的动词或说明某一事件的小句 加以“物化”， 从而浓缩成动词性名词。如：make decision， decision-making 名词化词组由于失去了动作的参 与者或发出者，在描述事件或说 明事物时显得更为 客观；因此，名词化是科技英语最重要的特征之一。 eg， If you expose the item for long, it will quickly deteriorate. Prolonged exposure will result in quick deterioration of item.
