The significance and purpose of the topic selection is generally the first content in the opening report, which is to explain whether the topic you are studying has research value or discussion value, and the purpose of writing the opening report. In fact, it is necessary to ask a tutor to judge whether our topic has research value, whether this research method is possible, and whether this argument logic has obvious defects. When writing meaning, you can decide the form according to your own topic, which can be divided into practical meaning and theoretical meaning. You can also write the purpose and meaning together without subdividing them. In short, you can suggest that you can describe it from these two points, but according to your own topic. Do not copy mechanically: 1. (Your topic) is a novel and meaningful topic that has not been studied by predecessors, that is to say, it has been ignored by predecessors. 2. Previous studies have been made, or although they have been elaborated, the discussion is not comprehensive enough. You should enrich it or refute the previous point of view. In short, the meaning and purpose must be clearly stated and there must be some new ideas. Secondly, pay attention to the theory you use. What theory do you use to prove your point of view should also be clearly stated, otherwise it will be difficult to be convincing, and there must be detailed basis in literature review and evaluation of research level at home and abroad to set off the significance of your topic selection.
