科研工作者在写SCI论文写作的过程中有没有这样纠结过：想投SCI分区和影响因子比较高的期刊，但是自己的英文写作水平比较一般，英文表达不够地道而被拒。对于硕博士来说，英语科技论文写作确实是让人内伤的一件事，特别是第一篇英文文章，总是迟迟难以下笔。小编特搜集了海量的资料整理了关于英文科技论文写作的一些要点。

很多同学在写文章的时候，往往想到某个意思，立刻脑子中想到都是例如I think, important, show, because, more andmore等等这些词汇，我们称这些为第一反应词，所谓第一反应词，就是每个人第一时间反应出来的这些表达。如果要写出一篇高质量的文章，除了内容，词的使用能够表现出你的英语能力，也是打动审稿人的一个重要环节。

和中文一样，英语也有同义词。使用一些经典地道的同义词，可以更有力、更生动地重新表达整个句子，以及降低论文的重复率；在使用同义词库来识别同义词时要小心，确保同义词符合语境。建议在以下的短语中穿插一些推荐的替换短语，使你的论文更加生动，用词灵活，文章表达更加地道。

根据写作内容和表达含义，这些同义短语可以分为6组：描述当前研究、概括研究背景、描述研究要素、讨论实验结果、说明实验方法、解释研究影响。

除了以上这些同义词组，在SCI论文写作中连接词的重要性也不能忽视，它就像是人的关节，是影响整体灵活性与完整性的重要环节。好的连接词能够让文章层次清晰，意思明确。
