写论文摘要时以一般现在时为主。
介绍背景知识时，要用一般现在时，例如：
Speech recognition is the task of converting speech into text.
语音识别是将语音转换成文本的任务。
叙述研究现状时，也可以用一般现在时，例如：
This essay is to analyse how the era influences corporate cultures, and to give suggestions on the building of corporate cultures.
本文旨在分析时代对企业文化的影响，并对企业文化建设提出建议。
叙述研究结果时，大多数用一般过去时，例如：
Our text achieved the possibility above.
我们的文本实现了上述可能性。
论文用到的专业性词汇比较多，很多时候在写英文的时候可能会感到困难，我用过的是这个，你看一下吧。
