Most students have never been exposed to papers during their undergraduate years. I give the following three suggestions:
First, writing experimental reports, course-related research reports and even summer internship reports during the undergraduate period can be packaged into scientific research experience; ?
Second, write your own graduation project. Some students write graduation thesis, so this is just your scientific research experience. If you don't write a thesis, you should also explain the research ideas, research methods, research process and research results of this graduation project.
Third, go back and read more papers and try to write one? 2000? A short essay on writing.
