1. Horizontal parallel structure. That is, put forward a central argument, and then refine the sub-arguments to discuss. (such as "Shi Shuo")

2. Vertical progressive structure. That is, put forward a central argument and analyze it from three aspects: "what", "why" and "how". (e.g. "encourage learning")

3. Positive and negative contrast structure. That is, put forward a central argument, demonstrate before and after, and give positive examples and counterexamples.

I take the first horizontal juxtaposition structure as an example:

The first part: put forward the central argument of the whole paper (positive, clear and accurate, about 100 words)

The second part: demonstrate the central argument (generally give three sub-arguments, analyze the problem, make the central argument stand up, about 600 words).

The third part: solving problems (the language is concise and appropriate, about 100 words)

The fourth part: the end (the language is powerful and full of philosophical connotation, 50- 100 words) (requirements: echo the beginning, propose by name and issue a call)

These are what the teacher told us in class. They are absolutely original.
