There are two reasons: first, most undergraduates have not engaged in specialized scientific research; Second, most undergraduates are not trained in scientific research methods.
Therefore, if undergraduates want to write a good thesis, my suggestion is that it is best to take a postgraduate or doctoral exam. There are special ways to cultivate scientific research talents, including tutors, professional courses, special scientific research conditions and funds, as well as the normative guidance of academic degree regulations and your special time. In this process, your original "high above" idea will be constantly corrected by your tutor, asking you to limit your own problems and focus on "small and deep" problems, commonly known as "digging holes"; When you dig deep and dig out your own novels and original achievements, you will naturally know and write high-level research papers and SCI papers.
People often use "groundbreaking" to describe major groundbreaking achievements, which is also commonly known as digging holes and breaking ground. By then, scientific writing and publishing methods will be used; Even without these methods, your innovation, that is, "content", can completely guide you to write and publish the best research papers. However, the most important thing is to cultivate your own ethical concepts and accomplishments in scientific research and publishing at all times, always remember and strictly follow them, so that your scientific research career will not be lost!
