Phenomenon is the external connection and surface feature of things, and the essence of things is often reflected through appearances. Every objective thing is a complex unity of various laws, which is manifested through colorful phenomena. When people come into contact with a thing, they always realize its colorful phenomena first, and get a perceptual knowledge of the whole thing from feeling, perception to appearance. By analyzing the phenomenon of things, we can help us understand the essence of things. Grasping the external relations and superficial features of things is the beginning of understanding, but understanding can't just stay on the surface. If we want to guide our understanding deeply, we need to further explore the internal characteristics and essential attributes of things, and rise from perceptual knowledge to rational knowledge. Therefore, before writing, we must carefully investigate and explore, and we must not make hasty judgments. Specifically, we should do the following: 1. Have a unique vision and observe things carefully. For junior high school students, don't let go of trivial things in life when observing. If we can open our eyes and use our brains to discover the profound meaning contained in the little problem of "sesame and mung beans", we can also get the outstanding idea of "seeing the essence in the ordinary and seeing the big thousand in the dust". At the same time, the essence of things often has a process of gradual exposure and development. Therefore, it is not easy to understand the nature of things. This requires us to strengthen our accumulation at ordinary times. Some dialectical materialism and historical materialism viewpoints in political textbooks should be absorbed and digested, and other wonderful theoretical books and articles should also be paid attention to from time to time. In this way, bringing a little "theoretical weapon" into the examination room and using it appropriately according to the needs will often get good results. Third, we should grasp some methods of "going deep into the essence", be good at using the light of rational wisdom, and make some efforts to "shake the leaves and seek the roots" under the observed appearance. When writing, we should pay attention to the use of comparative methods to summarize the phenomena of things, and then "rise" and "leap" to form a rational understanding of things. For example, 1995' s fable poem "Comment on Birds" describes the strange phenomenon that a group of birds expose their shortcomings and attack each other. When examining questions, we should first extract the essence of * * * and reveal the essential characteristics of these birds: they can't treat themselves and others correctly, comprehensively and dialectically. Otherwise, it is impossible to have a deep conversation. At the same time, pay attention to the dynamic analysis of the development process of things and explore the particularity of things in different stages of development. For example, if you write "tenacity-the character I pursue", you can use the method of process analysis to analyze the characteristics of various development stages that gradually become tenacity, and the factors that change from fragility to tenacity. When exploring the essential characteristics of things, we should also pay attention to: the same and similar phenomena may reflect different essence, while different phenomena may reflect the same essence. For example, 1997 college entrance examination composition requires combining the two materials provided by the test questions and thinking and discussing them in combination with reality. The first material tells that most teenagers appreciate "helping others" most, and the second material tells that many people will "walk away quietly" when others encounter difficulties. At first glance, these two materials reflect diametrically opposite phenomena. However, through careful analysis of the phenomena, we will find that the essence of these two different phenomena is exactly the same: selfishness is at work, and many people always want others to help them, but refuse to lend a helping hand when others are in trouble. Fourth, different styles have different methods of "going deep into the essence". Narration and description are the main methods of expression. In the article, "going deep into the essence through phenomena" is generally reflected through discussion and lyricism. The discussion and lyricism in narrative plays a unique role in embodying the "in-depth essence", although the space is limited. For example, it can deepen narrative content and sublimate emotions. Whether it is full of philosophical lyricism or giving the discussion vivid and emotional color, the essential meaning of these contents can be revealed through narrative content. Argumentative writing belongs to appeal to reason, so it is best to have profound philosophy, and of course, to "penetrate the essence through phenomena". Therefore, this paper should not only have a correct and scientific theory, but also make it as deep and practical as possible. Reasoning needs careful argumentation. Reason cannot be self-evident and self-evident. To understand, explain and popularize rationality, we must demonstrate, explain and prove it. Through careful argumentation, we can find the depth, breadth and strength of rationality. Reasoning needs strong persuasion, which is the fundamental goal of "going deep into the essence through phenomena", convincing people with reasoning and winning with reasoning, so that readers can truly accept the "essence" revealed by the author. 5. The core of the "essence" of things is "people's heart". In the final analysis, the core of the "essence" of things is the ideological root of people. Any bad social phenomenon will eventually catch up with "selfishness"; Any good social phenomenon, traced back to the source, will certainly catch up with the "public interest." For example, environmental problems seem to have nothing to do with "selfishness", but they are actually human problems, but if you ask a few more "why", you will find the root of the problem. Why does grassland decline? Isn't it because of overgrazing? Why do people overgrow? It is to meet people's growing demand for milk, cowhide and wool and make more money. So the key to the problem is that people are getting greedy. It can be inferred from this that all acts of destroying the environment are aimed at satisfying people's greedy desires. Therefore, everyone has an unshirkable responsibility for the destruction of the environment. Humans regard the environment that belongs to all life on this earth as a resource only for their own consumption. If we can analyze this, we will find the essence of the problem and the article will be profound.
