Problem Description: What is the definition of expository text?

Analysis: Expository essay is a genre of writing that uses explanation as the main expression to explain things and clarify things to give people knowledge. It illustrates the characteristics, essence, and regularity of things by revealing concepts.

The expository essay is very practical, it includes advertisements, instructions, synopses, tips, rules, charters, explanatory words, scientific sketches, etc.

In general, expository texts generally consist of three specific styles:

1. Those with a certain literary and artistic state burning model refer to scientific sketches, such as "Nanzhou June Lychee Dan".

2. Popular science, such as "March to the Desert" and "What is in the Universe".

3. Practicality, such as instructions, explanations, etc.

Expository essays generally introduce the shape, structure, category, relationship, and function of things, and explain the principles, meanings, characteristics, and evolution of things. "Shangshu Yugong" is the earliest explanatory text in China.

Expository essays are widely used, and are generally divided into two categories: plain expository essays and literary expository essays, and expository essays can also be divided into two categories: explanatory essays and explanatory essays according to the different objects and purposes of explanations.

Literary expository essays are expository essays that introduce scientific knowledge in the form of literature and art.

Expository essays are characterized by "speaking" and have a certain amount of knowledge. This kind of knowledge, whether it comes from relevant scientific research materials, or is obtained through personal practice, investigation, and investigation, is strictly scientific. In order to explain things, it is necessary to grasp the characteristics of things, and then reveal the essential properties of things, that is, not only to explain "what", but also to explain "why" that it is so.

An applied expository essay generally only needs to explain the characteristics of the thing, while an explanatory expository essay must reveal the origin and essence of the problem.

The explanation of the expository text must be orderly, and the order of the explanatory book is arranged according to the order of the things themselves and the laws of human understanding. For example, the introduction of scenery and architecture is mostly arranged according to the geographical environment and orientation layout; The origin and evolution of things are mostly arranged according to the order of time; The explanation of things is mostly arranged according to the logical order of things. In short, it is in a certain order, from the surface to the inside, from the real to the virtual, from the division to the combination, from far to near, from shallow to deep, step by step.

Sometimes, in order to make others understand things more accurately, under certain circumstances, as long as they do not violate the characteristics and laws of things, they can also make certain adjustments in the order.

Explanation is an expression method of explaining things and dissecting and organizing. Depending on the object, the focus and level of the explanation will be different. When explaining physical things, it is generally necessary to pay attention to the location of the space; When explaining abstract facts, emphasis is placed on explaining concepts, characteristics, structures, types, similarities and differences, comparisons, connections, and functions.

There are many ways to illustrate, and the common methods of explanation include definition, interpretation, comparison, analogy, categorization, examples, column numbers, column charts, etc.

Expository essay is a genre of essay in which explanation is the main mode of expression.

The explanation of objective things or the interpretation of abstract facts enables people to have a scientific understanding of the form, structure, nature, type, cause, function, and chain of things or the concept, characteristics, evolution, and differences of things. It illustrates the characteristics, essence, and regularity of things by revealing concepts.

Expository essays generally introduce the shape, structure, category, relationship, and function of things, and explain the principles, meanings, characteristics, and evolution of things. Expository essays are very practical, and they include advertisements, instructions, synopses, tips, rules, bylaws, explanations, etc.

Some expository texts are chronological, some are spatially ordered; Some are written from phenomena to essence, and some are written from primary to secondary; Some are explained in the order of the process, and some are explained in the order of the nature, function, and principle of things.

Definition is a method of summarizing the essential characteristics of things in concise and clear language. The following definition is a common method of explanation in expository texts.

When making a definition, it can be considered from different perspectives according to the needs of the purpose of the explanation. Some focus on characteristics, such as the definition of "person"; Some focus on the role, such as the definition of "fertilizer"; Some illustrate both characteristics and roles, such as the definitions of "integrated methodology" and "applied science".

The difference between definition and interpretation is that definition requires completeness, that is, the object of definition must be equal to the extension of the definition, and the whole connotation of the concept must be completely revealed from one aspect; Interpretation does not require completeness, but only the revelation of a part of the concept, and the object of interpretation and the extension of the interpretation can not be equal.

1. Definition: "It is necessary to grasp the basic properties and essential characteristics of the defined thing, for example, in the form of judging a single sentence." The format is mostly "species concept) is the genus concept)", such as:

An irrational number (a kind of concept) is a decimal number (genus concept) that is infinite and not cyclical (essential characteristic); or " is called e.g. an infinite and non-circular decimal number is called an irrational number.

2. The role of the definition:

Use concise and scientific language to reveal the scientific facts of the objects of explanation, so as to reveal the characteristics of things in a more scientific, essential, and general way.
