1. Example method. It is an argument method to prove the argument with examples. It is the most basic and commonly used method in argumentative writing. "Facts speak louder than words", used well, can often enhance the persuasiveness of articles. First of all, we should pay attention to the selection of examples. The selection of cases should be true, typical, full and fresh. Choosing an example as true means that the selected example, whether experienced personally or indirectly, must be true, reliable and accurate; The selection of examples should be typical, that is, the selection of examples should be representative, not too many, but precise, so that one can be ten, and less wins more; Choose enough examples, that is to say, there must be a certain number of examples. When choosing examples, we should take care of all aspects. Several examples have the same attributes, which can better explain the essence of the problem; Choosing new cases means consciously choosing some new cases in real life, which is both targeted and zeitgeist. Secondly, pay attention to examples. The purpose of giving examples in argumentative essays is to prepare for a round, so it is required to be concise and highly summarized. Colleagues should summarize the case according to the needs of the argument and pay attention to highlighting the part of the case closely related to the central argument. Finally, we should pay attention to discussing cases. On the basis of selecting and describing cases, we should be good at discussing cases. Analyze and explain the case, reveal the connection between the case and the argument, and make the case really play the role of proving the argument, so as to achieve the combination of narrative and discussion.

2. Introduce the method. It is an argument method to prove the argument with theoretical argument. When quoting theoretical arguments, we should pay attention to the following points: (1) accuracy. For the cited theory, we should deeply understand its meaning and consider whether it is different from our own point of view. Never be far-fetched. (2) conclusive. The quoted remarks must be reliable, stand the test and be proved to be objective truth. Whether you quote the original text or the main idea, you should check it carefully. (3) accurate. The theoretical materials cited should be carefully selected, not too much, and enough is enough. (4) flexibility. Quoting famous sayings should be flexible and diverse, not too rigid and lacking some changes. Sometimes I quote directly, sometimes indirectly, sometimes I quote the original text, sometimes I quote the general idea, and sometimes I insert the quoted words into my own analysis.

3. Contrast method. When writing an argumentative essay, the positive and negative contrast method is cited to demonstrate, which is the positive and negative contrast method, referred to as the contrast method. The characteristic of contrast method is to compare and analyze two or more different things, or agree that things are two different situations, to form a sharp contrast, so as to draw a judgment conclusion and prove that the positive view is correct and the negative view is wrong. There are many ways to compare. It can be a comparison of two viewpoints or two arguments, but it can be a comparison before and after agreeing with the thing itself (vertical comparison) or a comparison between two things.

4. Metaphor. It is an argument method that uses familiar things as a metaphor to clarify the truth. Metaphor can make articles vivid and appealing, and its main function is to make abstruse truths simple and abstract truths concrete. When using metaphor, we should pay attention to: (1) The vehicle and the argument must be two completely different things, but they are very similar, so it is appropriate. When demonstrating, make an analogy and then analyze it, and prove the reliability of the argument through metaphor. (2) Metaphor is sometimes demonstrated with a single vehicle, and sometimes with a group of metaphors to prove the same truth. For example, in the article "Takeism", Lu Xun compared the cultural heritage to a big house, compared a part of the cultural heritage with shark's fin, opium, guns and cigarettes, and aunts, and used a set of metaphors to illustrate the truth. (3) Metaphor can be combined with other argumentation methods to enhance the effectiveness of argumentation.
