What is the function of classification? How to explain the classification?

It is often difficult to explain the characteristics of things unilaterally. According to the similarities and differences of shapes, properties, causes and functions of things, things can be divided into several categories, and then explained one by one according to the categories. This interpretation technique is called classification.

What are the benefits of classification? Classification can explain things clearly. Classification is an important way to clarify complex things.

The characteristics and essence of some things need to be divided into several points or aspects, which also belongs to classification.

Classification can divide things into several categories according to the similarities and differences of shapes, properties, components, functions and other attributes, and then pay attention to explaining them according to categories.

For example, in Seeing the Weather from Clouds, the clouds in the sky are divided into eight categories: cirrus, cirrocumulus, cumulus, altocumulus, nimbostratus, cumulonimbus and cirrostratus and explained.

Example of classification interpretation method 1:

Classification: Prepare description methods for classifying description objects according to different standards, such as

Sentences can be divided into four categories according to usage: declarative sentences, interrogative sentences, imperative sentences and exclamatory sentences.

2. According to the structure, sentences can be divided into four categories: simple sentences, complex sentences, complex sentences and coordinate complex sentences.

3. According to rhetoric, sentences can be divided into loose sentences, circular sentences and antithetical sentences.

Definition: an explanation method prepared to grasp the essential characteristics of things, which is generally expressed by "what", such as

1, a square is an equilateral rectangle!

2. Carbon dioxide is the combustion of one carbon atom and two oxygen atoms into carbon dioxide.

3. Parallelogram is two groups of parallelograms with parallel opposite sides.

Two:

From the perspective of the relationship between explanatory objects, there is a subordinate relationship between classified explanatory objects and classified explanatory contents; There is a parallel relationship between the two things being compared. For example; For example, there are similar comparisons and heterogeneous comparisons. Similar comparison is to compare two aspects of the same thing, while heterogeneous comparison is a different thing.

Three:

What is classification? According to certain standards, the interpreted objects are divided into different categories and explained one by one. This method of explanation is called classification.

The function of classification: it can explain things clearly. Classification is an important way to explain complex things clearly.

When using the classification method, we should pay attention to the classification standards: only one standard can be used at a time to avoid overlapping.

For example, "The books in the library are China, classical, foreign, scientific, literary, modern, political and economic, etc." More than one standard is used here, so it is unclear. The correct statement should be: the books in the library are divided by country, including China and foreign countries; According to the times, there are classical and modern; By nature, there are science and technology, literature and political economy.

Only used for each category.

A standard can make it clear.

Other aspects: the characteristics and essence of some things need to be divided into several aspects, which also belongs to classification.

Classification can divide things into several categories according to the similarities and differences in shape, nature, causes and functions, and then pay attention to the explanation according to the categories.

Example 2: Divide the clouds in the sky into cirrus, cirrocumulus, cumulus and altocumulus and explain them.
