Aim at the target. To write an argumentative essay, we must first set out the fallacies or reactionary views of the other side and set goals. How to set goals? There are usually two methods. The first is an overview. That is, retelling the refuted enemy theory in popular language. And also emphasized the disadvantages of the enemy theory. When summing up, you can quote some original words appropriately, but it should be focused and the tendency should be clear. The second is the quotation. That is, extract the key parts or related parts of negative materials, and then refute them against the target. You can quote some typical examples and classic famous sentences. Prove your point more forcefully.

(2) Grasp the key points. Lu Xun said: "It is the key to' discussing the enemy'. It only takes one blow to cause fatal harm to people." We must grasp the reactionary nature of fallacies and heresies and expose and criticize them in depth.

③ Pay attention to discretion. We must distinguish between the enemy's counter-revolutionary fallacies and the wrong ideas among the people. Expose the enemy mercilessly, denounce the enemy and give a fatal blow; We must adhere to the principle of "unity-criticism-unity" for erroneous ideas among the people, and we must never compare them.

1, first establish an argument. This paper focuses on this argument. The statement that "opening a book is beneficial" can neither be completely denied nor completely refuted; It is also inappropriate to be sure of everything and write a paper. Because this statement has its right side. There are also some places that are not comprehensive enough. We should adopt the method of "splitting into two" to analyze this view, affirm its beneficial side, deny its harmful side, and sum up the correct argument from it. Only in this way can we make a factual evaluation of this statement and finally achieve the purpose of convincing people by reasoning.

2. Analyze with the method of "one divides into two" to prevent such a problem: self-contradiction. In an instant, opening the book is beneficial, and in an instant, opening the book is harmful and confusing. In order to avoid this phenomenon, it is necessary to point out the connection between the two in the article in order to truly explain the truth.

3. From the argument method, if the book you read is not good, it may not be good to open it. Here, we can take examples, supplemented by citations and metaphors, take the flood of pornographic books in society in previous years as factual arguments and famous sayings as theoretical arguments to fully demonstrate the harm of pornographic books and the benefits of reading good books. On this basis, the two are unified in the right way. It shows that we middle school students should not only read more books, but also choose carefully and read good books. In this way, from both positive and negative arguments, the problem will be more comprehensive and profound, and the article will have irrefutable logical power.
