? For example, 20 13, a survey of vegetable price fluctuation in a county of Heilongjiang Province. Specific to a small place and a single event, it is easy to control variables and draw certain conclusions and results. The most taboo topic of this paper is that the scope is too large, such as the study of china dairy's development strategy, and so on. The review teacher will give you a negative if you don't look at it.

? Secondly, after the topic is determined, there will be two situations. First, you want to write your own paper, but in order to graduate, the teacher will give you some materials to make a paper according to the template. I take you as the first case here. It is best to look at all the papers with similar topics to yours in recent years through HowNet, understand the latest research progress in related fields, and mark the marked ones. These will be your reference.

? Please investigate on the spot to obtain real data to prevent the conclusion from being wrong. Then model, judge the data and draw a conclusion. This is the basic preparation before you write your thesis. The preliminary work is heavy, but writing a paper is relatively simple. Every year, every school has some changes in the paper template. Just follow the template of the year and leave nothing behind.

? These are my personal views, and I hope to help you.
