据学术堂了解,英文表达有16种时态,论文中要用到的时态主要有一般现在时、一般过去时和现在完成时.一般现在时:主要用于不受时间限制的客观存在事实的描述,或发生或存在于写论文之时的感觉、状态、关系等的描述或致谢的表述等.值得 注意的是,出于尊重,凡是他人已经发表的研究成果作为previously established knowledge,在引述时普遍都用一般现在时.一般过去时:用于写论文中作者自己所做工作的描述.例如描述自己的材料、方法和结果.现在完成时:完成时少用.现在完成时把过去发生的或过去已完成的事情与现在联系起来.比如在介绍研究方法、分析某个问题或提出某个论证时,使用一般现在时.在叙述对本人或他人近期的工作或认识时,采用一般过去时或过去完成时.叙述结论或提出建议时,可使用一般现在时以及使用may,should,could等助动词.例如,当提到本文、此图、此表等说明了、表达了什么时要用一般现在时,而不用一般过去时.This paper describes The focus of this paper is Figure 1 shows Most of the mon condensation polymers are listed in Table 1-1.结论部分可以使用过去时强调过去的研究成果,采用现在时或将来时表达未来的研究方向或研究前景.Although the study found evidence of tillage and irrigation within the study area,from the data collected it was not possible to determine if the effects of agriculture upstream cause (or caused) higher levels of total nitrogen downstream. Further studies are therefore necessary to determine the effects of agriculture on the health of Stringybark Creek.
