Natural paragraphs can express clearer scenes, concepts, actions, etc. It is the smallest language unit that constitutes a work except words and sentences.
A natural paragraph consists of several sentences, each sentence is coherent, forming a natural paragraph. On the contrary, it should be divided into two natural segments. Several natural paragraphs can form a large paragraph to express the development of a related thing, or they can directly form an article, that is, the article has only one question or one thing, and so on.
"Natural paragraph" is also called "punctuation paragraph";
An article usually consists of several levels and paragraphs. A level usually contains several paragraphs, so it is also called "large segment" or "functional segment". Paragraph is the pause caused by the separation, turning and emphasis of the content of the article, and it is the smallest structural unit to express the level of the article. It has obvious external signs in form (usually the first line is indented by two spaces), which can be known at a glance without discrimination, so it is also called "natural paragraph" customarily.
"Natural paragraph" can be regarded as a punctuation form to express discourse pause and text structure. In fact, it is not naturally formed, but a man-made "punctuation paragraph". Sentences, sentences and sentence groups, sentence groups and sentence groups in a paragraph are arranged in a certain logical order, which also reflects a certain hierarchical relationship.
There are connections and differences between levels and paragraphs. The hierarchy focuses on the division of ideological content, showing differences in logic; Paragraph focuses on the needs of text expression and readers' understanding, which is the external expression of relatively independent meaning in discourse. Levels are always displayed through certain paragraphs. Generally speaking, a level is larger than a paragraph and can contain several or even dozens of paragraphs, but sometimes the level with simple content has only one paragraph. Segmentation is to show the hierarchy with punctuation marks, so that readers can understand the hierarchy through paragraphs.
In addition to most ordinary paragraphs, the article also has a beginning paragraph, a transition paragraph and an end paragraph. Special paragraphs have dialogue paragraphs, which are more common in literary works.
