What Is a Paragraph Break?

It is one of the most important punctuation marks. A paragraph break is an indentation（缩造）or a single line space    1    the division between one paragraph and the next in a body of text.

Generally, paragraph breaks serve to    2    the transition from one idea to another in a stretch of text, and from one speaker to another in an exchange of dialogue.

Few readers would think of the paragraph break as a punctuation mark, but it certainly is. In ancient times there were no paragraphs. Sentences simply flowed into one another without    3    .During medieval（中世纪）times, the mark evolved into the paragraph symbol and eventually became the modern-day paragraph break, which is    4    now only by a line break or indentation.

Today, the paragraph break is used to give readers a break. The art of creating paragraphs is called paragraphing, the    5    of dividing a text into paragraphs. Paragraphing is a kindness to your reader because it divides your thinking into manageable bites. Paragraphs that are too long    6    readers with dense blocks of text to read through, while more frequent paragraphing provides readers with convenient    7    points at which to take a break and relaunch themselves into thinking.

To fully understand when to insert a paragraph break, it’s helpful to know that a paragraph is a group of closely related sentences that develop a central idea. Therefore, each paragraph discusses one    8    topic. Also, a paragraph break is cmploycd before each new topic is introduced. In this way, the writing will flow, and readers will be able to proceed through the writing in a logical fashion instead of    9    all the way to get to the last line.

Paragraphs used to be longer, but with the development of the Internet, which gives readers access to literally millions of sources of information, paragraphs have become increasingly    10    . The style for many websites, for example, uses paragraphs no more than two to three sentences.
