A natural paragraph is the basic unit to express meaning in an article. It has an obvious sign, that is, "newline space". At the beginning of each natural paragraph, there is a new line with two blank spaces.
It is mainly determined by punctuation marks, such as' period, question mark and exclamation mark' when a sentence is finished, so it is easy to judge several sentences. Under special circumstances, a sentence also has a special symbol.
Poems are written with lines, so they can't be counted as stanzas (natural paragraphs). Poetry is generally divided into chapters with blank lines, that is, every other line, such as Tent and The Story of Fisherman and Goldfish.
In my opinion, the natural paragraph numbering of epistolary articles begins with greetings, and addresses, signatures and dates are not numbered, because this is a relatively fixed and unique format of epistolary articles; Greetings and greetings vary from person to person, and their expressions may be different. Sometimes there is not necessarily only one natural segment, but also two or three natural segments or even longer.
