第一，摘要中的第一句话不要与文题重复,要有所变化，补充一些细节。如文题为：Expression of RACK1 in primary colon cancers.则摘要第一句话不要写为To detect the expression of RACK1 in primary colon cancers.最好改为To detect RACK1 gene over-expressed in primary colon carcinoma by in situ hybridisation.
第二，可用动词的情况应尽量避免应用动词的名词形式。如:应当用Her-2 oncogene amplification in prostate cancer was measured.而不用Measurement of Her-2 oncogene amplification in prostate cancer was made.
第三，正确使用冠词，包括定冠词the和不定冠词a或 an；区分可数名词和不可数名词是关键。如expression做（基因）表达用时为不可数名词，不能加s.对可数名词尽可能使用其复数形式。
第四，应当用预置短语分开或用连字符断开名词词组，SCI论文避免使用连续多个形容词或名词来修饰名词。如用sections of formalin-fixed and paraffin-embedded tissues,而不用formalin fixed and paraffin embedded tissue sections。
第五，注意平行结构：在表述各相同的并列成分时，不论是词类、词组、从句或分句，每个成分都必须对等。如The purpose of this study was to yze the new proposed classification and determining which classification was clinically useful.其中第二个表语是动名词短语，与第一个表语不定式短语不一致，不符合平行结构原则。
第六，SCI论文比较必须在同类的事物之间进行，切忌对不同类型事物进行比较。例如：The survival of patients with MSI+ phenotype was better than MSI- phenotype.此句比较对象不对等，应改为The survival of patients with MSI+ phenotype was better than that of patients with MSI- phenotype.
