随着高科技和信息时代的到来,专业英语在全球科技合作与交流中发挥着越来越重要的作用。为了适应新时期信息技术人才培养的需求,我国许多高校都开设了专业英语课程,此类课程的开设对于拓宽学生知识面,提高科技语言的运用能力,培养国际型人才起到了促进作用。与此同时,专业英语教学的发展也推动了专业英语教材的编写以及对教学方法与手段的探索和研究。专业英语的篇目选材一般取自国外最近几年IT各个领域的最新教材、专著、论文等,这些科技文献崇尚严谨周密、概念准确、逻辑性强、行文简练、表达客观。

由此可见,相对于通用英语(English for General Purposes)和一般社交英语来说,专业英语在词汇、常用句型、表达方法和语言风格等方面都具有许多不同的特点,掌握这些特点可以有效地提高学生的科技阅读、翻译和写作能力。而通用英语学习的主要目的是使学生掌握一般情景中使用语言的技能,因此当学生最初接触专业英语时,由于对专业词汇和语言特点不熟悉,往往造成对文章内容理解的困难,或在科技英语写作、翻译中出现语言使用不得体、不准确等问题,加之学习内容比较陌生或枯燥,因而对专业英语学习失去兴趣和学习的动力。
