Articles can be regarded as expository or argumentative. Generally speaking, it is to quote something else to prove a point.

Wikipedia Introduction: Generally speaking, an article is an article that gives the author's own arguments-but the definition is vague and overlaps with the definitions of articles, pamphlets and short stories. Traditionally, articles have been subdivided into formal and informal. Formal articles are characterized by "serious purpose, dignity, logical organization and length", while informal articles are characterized by "personal factors (self-disclosure, personal taste and experience, confidentiality), humor, elegant style, loose structure and unconventional theme".

The general meaning is an article, which puts forward the author's own arguments, but this definition is vague and overlaps with the definitions of articles, pamphlets and short stories. Papers are generally divided into formal and informal. Formal papers are characterized by "serious purpose, dignity, logical organization and length", while informal papers are "personal factors (self-disclosure, personal preferences and experiences, confidentiality), humorous and elegant style, loose structure, abnormal or novel theme" and so on.

You probably understand this explanation, right? In fact, the essence of composition is to give your own arguments. Then prove him, prove him, prove him.
