小白讲实验，带你走进科研殿堂，助你从实验小白变身科研达人实验小白小编既没有出过国，英文也不好。小编写SCI文章基本上都是靠“借鉴”，平时看文献遇到好的句子会摘录下来，以备写SCI文章的时候使用。因此，小编只能抛砖引玉，期待更多有SCI写作经验，英文好的小伙伴分享经验。 这一期分享的内容是“The NCBI Style Guide”一书中关于学术文章写作的时候的时态的使用规范。 Scientific English: Past, Present, and Simple(SCI写作中常用一般现在时和一般过去式) Some authors, especially those whose native language is not English, are not as aware that the use of past and present tenses signals the status of the presented information.（说的就是小编这样的土鳖） Established knowledge (statements of fact, natural laws, universal (established) truths, or a widely held tenet of science) is given in the simple present tense.(既定的事实用一般现在时) The new results and findings of an author's own research are given in the simple past tense. （在阐述作者自己新的结果和发现时候用一般过去式） Once an author's findings are published and become an established truth (generally accepted by experts in the field), they are referred to in the present tense.（在引用一个作者已经发表的结果的时候，常用一般现在时） 
The use of the simple present tense signals that something is a general truth, the reader is given some feeling of certainty about the information. 
The use of the simple present tense when first presenting one’s own findings could be perceived as arrogant as well.（如果在描述自己第一次发表的结果的时候使用一般现在时，会让人觉得你是一个愣头青） Even the demonstration of significant results in one's own study is not a reason for using the present tense in the Discussion section of the paper first reporting those results.（即使在讨论中阐述结果的意义的时候也最好不要使用一般现在时。但是小编发现更多的文章在摘要和讨论的最后一句These data suggest that....的时候使用一般现在时，其他地方大多用一般过去式） Note to Authors: To avoid misunderstanding, report your findings in the past tense.（保险起见，最好还是用一般过去式阐述你的结果） The explanations of graphical presentations of data, such as tables and figures should use the present tense. （在解释图和表的时候应该用一般现在时） For example, when referring to Table 3, it is fine to say: “Table 3 shows that the mean yield is lower than expected.”. 或者在图注中：比如“Figure 7 CD138 ASCs accumulate in TFR-cell-depleted mice.”(摘自于Nat Immunol 2017, 18(11):1249-1260，但是在图注中具体描述的时候还是用一般过去式.) 期待更多的小伙伴分享SCI论文写作经验！ 投稿&合作联系：微信号'Cjer0201'. |
