Classical Chinese broken sentences:
First of all, we should correctly judge the style of sentences to be broken. If it is a biography with a story, it is necessary to master its general plot, central events and character relationships; If it is an argument, it is necessary to clarify the discussion center of this article, and then further clarify the logical relationship between the front and back according to the center. In short, before breaking sentences, you must read through the given article several times and try to grasp the main idea of the article as much as possible.
For the parts that are easy to break sentences, you can directly add diagonal lines or punctuation marks; For those who are temporarily uncertain, we can put them aside for final consideration.
