For most students, this is their first time to write a paper. When they first started writing papers, they had no clue, so the most direct way was to learn from other papers. Now there is a problem. Whether the patchwork of many papers is plagiarism depends mainly on how people pieced together the papers.
If you copy a paragraph directly and then piece it together, it must be plagiarism, because if you copy a paragraph from this paper like this and a paragraph from that paper, there is no modification at all. When you check the duplicate, the repetition rate of the whole paper will definitely exceed the standard.
Moreover, our current paper detection system is also very accurate, as long as plagiarism can be detected. Therefore, if you want to piece together many papers, you must use certain methods. Only in this way can we ensure that the repetition rate of this article you wrote will not be high and will not be judged as plagiarism.
One way to piece together is to piece together ideas. For example, you can find something that fits the theme of your paper, and then sort out the ideas of these papers first. Then write some important contents in this paper in your own words. Papers pieced together in this way are generally not plagiarism, but ideological imitation.
