主要分三部分：
01. 写作中常出现的语法问题
SCI写作中经常会遇到语法问题，特别需要注意的有：
a 主语和谓语的单数和复数要一致（单数主语名词+动词单数形式，复数主语名词+动词复数形式，这是个非常容易犯错的语法）
例1: A high percentage of peptides that are made of amino acids are present in the sample.
A high percentage才是真正主语，所以用单数is
b 修饰语同主语名词要一致(当用动名词/分词短语/不定式短语作修饰语时，修饰语中的动词要同主句中的主语名词关系上要一致)
c 主语和主语的行动（谓语）在逻辑上一致
d 代名词和记代理的先行词要一致
02. 常用词汇
论文写作中特别注意用词要准确，科技论文一定要注意准确用词，用词不确定时最好查字典。
例如promote一般指职位的提升，在论文中这就不能当increase来使用。
a 结论或者推理的词汇
从实验观察和数据到结论的推理过程中，在事实和理论的关系上可能有从“与…一致”到“表示”到“证明”等不同关系，在选择用词上要合理。英语中常用的词是：is compatible with, imply, suggest, show, indicate, prove从前到后是一个从弱到强的顺序。
is compatible/consistent/line with表合理解释，不矛盾但可能还有其他解释。
imply/suggest表示支持现在的结论，这个结论比其他的更加合理，但不能证明就是这个结论。
indicate/show/demonstrate更加确定，表示就是这个结论了，其他可能性不大。
prove表示完全肯定，没有任何其他可能性了，科研中很少有这种情况，用prove要注意。
b 用词保持一致
论文从头到尾用词要保持一致，特别是单位。比如时间单位分钟，可用全拼minutes,也可简写成min,但只能用一种写法，再例如Figure或Fig也只能二选一。
c 描述课题意义和重要性的词汇
associate with/attention/characterize/composed of/consist of/evidence/interest/involve/relate to/ participate/role

h 描述先后顺序的词
follow/immediate/instant/in the course of/during the course of/simultaneous/ subsequent/then
i 描述实验结果的词汇
affect/alter/analyze/confirm/consider/detect/determine/develop/distinguish/exert/exhibit/illustrate/interact/lead to/manipulate/mediate/modify/show/ modulate/observe/present/result in/retain
j 描述减少/降低/阻碍等词
decrease/hamper/inhibit/prevent/reduce/suppress/elevate/enhance/increase/raise/stimulate
k 用于比较的词语

l 常用修饰词
apparent/clearly/compelling/completely/considerable/critical/dramatic/essential/exactly/exclusively/extremely/highly/likely/nearly/permanently/potentially/precisely/predominantly/radically/readily/roughly/spontaneously/strongly/substantial/surprisingly/thoroughly/approximately
