【摘要】 现在科技英语已经发展成为一种很重要的英语文体。这种文体具备其自身特点。其中之一就是大量使用被动句,省略句,松散句和倒装句( Chen Xin, 1999).许多学者已经探讨并研究了各种英语句式的信息传递功能并且得出了很多结论。但是极少研究涉及科技英语中否定句的信息传递功能。因此,作者通过随机抽样法,以美国科技杂志月刊《科学美国人》2005年单月刊为研究对象,将其中的否定句进行归纳总结。作者把以前语言研究者所得出的八种信息传递功能运用到科技英语否定句中,并且从微观的角度,即从否定句中的否定结构组织成分上来进行细致深入地分析,总结出科技英语否定句中最常用的三种信息传递功能,逐一进行微观分析,得出几处与前人不同的结论和三个新发现。在此基础上,作者对科技英语否定句中出现频率最高的三种功能进行了详细分析和研究,在其结构组织成分对信息传递所起作用上提出了很多新观点。更多还原

【Abstract】 Nowadays EST (English for Science and Technology) has become a very important genre of English. The genre of EST has its own distinctive linguistic characteristics, one of which is that a large number of sentences with the structures of passive voice, ellipsis, breaking-up and inversion (Chen Xin, 1999). Many scholars have probed into a variety of English sentences in the area of message transmission and some suppositions are offered by them. However, few researches concerning negative sentences in EST area have been found.Therefore, the author has summarized message transmission functions of negative sentences in EST texts through a careful analysis of the sampling negative sentences from EST journal papers chosen randomly from a magazine entitled the Scientific America in the year 2005 (only the single-month versions from January to October), and wrote down all the negative sentences appearing within this range. The author applied the seven information transmission functions offered by previous language researchers into negative sentences in EST materials and analyzed the top three most frequently used information transmission functions from a microcosmic angle, that is , from the components of each negative structure, and then did analysis of it one by one in detail, and concluded differently for several points and made three different discoveries.Based on the above, the author has provided more detailed and careful description of two information transmission functions, which are the top two functions appearing most frequently in the negative sentences of EST literature and put forward many new ideas about the effect of the structural components of the negative sentences of EST materials on information transmission. The two functions are: the function to emphasize a topic, and the function to describe a topic in an objective way.更多还原
