To put it bluntly, the significance of choosing a topic is that you have chosen this topic. What do you think is unique about what you study or write, and what significance it may have for society, this academic community or life.

First of all, you have to understand your paper, and the last trouble is yourself. I'm tired of going to the teacher for revision over and over again. Of course, writing a paper still needs the help of the internet and books. Therefore, you must master the context of the whole paper and write these auxiliary things on this basis, otherwise you can only write too far from the point or the words can't convey the meaning.

Basic structure: 1. Briefly introduce the structure of your thesis, 2. Write down the original place of your paper or the place where you found something, 3. Discuss this place and output what you think this point means.
