Just kidding. Usually, the point of view of writing a paper is not your own point of view, but copying other people's points of view (equivalent to direct quotation), but the place (author and source of the article) is not given.

The worst case is that the whole article is not written by yourself. For example, the teacher gives a topic, and then students directly submit articles written by others on the same topic to the teacher. This is the worst plagiarism case.

There is also a kind of article that is written by oneself, but the sub-argument directly quotes other people's arguments and paragraphs, without giving any credit to the original author (without indicating the original author and the source of the book). This is also plagiarism.

There are also direct quotations, and the credit of the original author is also marked (indicating the original author and the source of the book). However, if there are many direct quotations in the whole article, and almost every paragraph has direct quotations, it is directly judged as plagiarism.
