I think judging the gold content of a paper can be judged from two major directions. One is the paper itself, and the other is what is attached to the paper.
Let's look at the paper itself first. Whether the argument is clear It seems easy to judge whether the argument is clear, but an experienced teacher who has actually done a paper can see whether the paper is valuable from its title.
For example, I am studying modern and contemporary female images. Comparing Xiao Hong and Zhang Ailing will be very impactful and informative, but you compare Xiao Hong and Bing Xin. Please, there are not many women created by Bing Xin, who are not systematic and have no distinct personality. Although the topic is novel, it is unreliable at first glance.
Discuss whether the skills are solid. At first glance, some papers seem to be piecing together words. What can be made clear in one sentence has to be dragged on for several paragraphs without telling everyone. You can expect such a paper to contain a lot of gold.
Look at something attached to the paper.
First of all, of course, the author. If the author is a great scholar, especially this paper was produced in the heyday of his youth, it is really worth reading.
Secondly, look at the citation rate. Some papers do have a high citation rate, and this thesis argument is definitely worth learning because it is recognized by the industry, and then you can learn how to express it.
Finally, look at the source of the quotation. Papers with high gold content, cited works or periodicals are well-known, and they have been strictly screened and will never be cited by anyone.
