APA format specification mainly includes three parts: title, in-text citation of article content and bibliography after the article ends. The basic structure of MLA-formatted papers is: the first four lines are aligned to the left, followed by: student's name, teacher's name, course number, writing date, the title of the paper written in the middle of the fifth line, the body at the beginning of the sixth line (including several paragraphs, namely introduction, body and conclusion), and finally references are attached.

APA format is formulated by American Psychological Association, which is widely used in writing, quoting and formatting papers in research and writing in psychology, education, social science and other fields.

MLA (Modern Language Association) is a commonly used citation format. It is the paper guidance format of the American Modern Language Association. When writing English papers, MLA format should be used to ensure the integrity of academic works.
