Express the explanation of the above words or express a change in some sense. The first function of dashes is to explain the above. This usage is similar to brackets.
The difference between the two is that the sentences marked in brackets are only the above explanations, not the text, so they don't need to be read out when reading; The sentence marked with dashes is not only the explanation of the previous paragraph, but also a part of the text, which must be read in context. So pay attention to the difference between the two when commenting on the above. If the comment part is the text, use a dash; If it is not text, please use parentheses. The explanation of a written form is usually led out by only one dash. If such a sentence is inserted in a sentence and it is very long, you can use a double dash, that is, the first comment and the last comment. The second function of dashes is to express progressive meaning. In this case, we can usually see the passage of time before and after the dash, the advancement of meaning, the transfer of space and the change of plot. The third function of dashes is semantic transformation. In batch language expression, one meaning suddenly turns to another meaning, and dashes are not the same content. The fourth function is to express the pause, pause and extension of sound. In addition, dashes are also used to connect two-part allegorical sayings, indicating the subtitle of the article and the author of the words, poems and articles, as well as separate items.
