Asking questions, analyzing problems and solving problems is a common way of argumentative writing structure, also known as vertical structure or hierarchical structure. It is a structural way to discuss according to the logical level of problems and theories, or from phenomenon to essence, or from cause to result, or from general to special, from shallow to deep, step by step and vertically.

Why use this structure is because it can reflect meticulous thinking and make the article more flexible and personalized. It can clearly express the author's point of view and argumentation process, so that readers can follow the author's ideas and understand the author's intentions. Generally speaking, you can write according to the following steps:

1, Introduction: Put forward a general argument or lead to a topic.

2. This theory: put forward sub-arguments and analyze them in depth at different levels.

3. Conclusion: Summarize the full text, summarize opinions, and put forward suggestions or prospects.
