I asked the teacher if there was anything wrong with my paper. The teacher said what do you think? I can answer like this: Teacher, my knowledge, experience and knowledge are not as rich as yours. If my paper is not well written, I hope you will correct me. Papers are often used to refer to articles that conduct research in various academic fields and describe academic research results. It is not only a means to discuss problems in academic research, but also a tool to describe academic research results in academic exchanges. Including academic papers, graduation papers, dissertations, scientific papers, achievement papers and so on.
