1. Argument is clear: the core of an argumentative paper is an argument, that is, the viewpoint or position that the author wants to express. The argument should be clear and concise, which can arouse the reader's interest and thinking.

2. Sufficient arguments: arguments are evidence or reasons to support arguments. The author should provide sufficient, concrete and reliable arguments to prove the correctness and credibility of the argument.

3. Reasonable argumentative structure: An argumentative paper should have clear structure and logic. The structure of "introduction-argument-argument-conclusion" is usually adopted, and the rationality and persuasiveness of the argument are demonstrated through a reasonable argumentation process.

4. Strict logical reasoning: The author should use strict logical reasoning to organically link arguments with arguments, so that the argumentation process has inherent logic and coherence.

5. Accurate language expression: Argumentative papers should express opinions and arguments in accurate, concise and vivid language. Avoid using vague and ambiguous words and expressions to avoid confusing readers.

6. Diversified argumentation methods: The author can use different argumentation methods, such as giving examples, comparing and quoting authoritative opinions, to enhance the persuasiveness and credibility of argumentation.

7. Analysis for readers: The author should understand the background, viewpoints and needs of readers, so as to make targeted arguments and refutations and make the article more convincing.

8. Appropriate style and tone: An argumentative paper should adopt an objective and rational tone to avoid emotional and personal attacks. At the same time, according to different writing purposes and readers, choose the appropriate style and tone.

In short, writing an argumentative essay requires clear arguments, sufficient arguments, reasonable argumentation structure, strict logical reasoning, accurate language expression, diverse argumentation methods, analysis for readers, and appropriate stylistic tone. Only by comprehensively considering these elements can we write an excellent argumentative essay.
