In classical Chinese, sentence breaks were used to divide the positions of pauses in a sentence when reading classical Chinese. The key to breaking a sentence was to determine the subject, verb, object, and other components in the sentence, as well as their relationship with these components. Below are some techniques for breaking sentences in classical Chinese: 1. Observe the structure of the sentence, especially the position of the subject and the verb, and separate them. The subject is usually at the beginning of the sentence and the predicates are at the end of the sentence. 2. Use the influence of auxiliary words and mood particles. Particles such as "hu","yu","er","zhi","ye","yi","yan", etc., as well as mood particles such as "bu","zhi","ye","yan", etc., can affect the pause of a sentence. 3 Pay attention to the person and number of the verb. Verbs in classical Chinese sometimes have different pronunciations and numbers, such as "I","you","he","she","we","you" and so on. Therefore, when breaking sentences, one needed to judge according to the different person and number of the verb. 4 Consider the tone of the sentence. Modal particles in classical Chinese often affect the pause of sentences, such as exclamation sentences, interrogative sentences, imperative sentences, etc. Therefore, one needed to judge the sentence based on the tone of the sentence. 5. Make use of the characteristics of sentence patterns. Different sentence patterns have different effects on the sentence pause, such as the S-V consistent sentence pattern, the S-O consistent sentence pattern, the S-O preposed sentence pattern, the object preposed sentence pattern, and so on. Therefore, one needed to judge according to the characteristics of the sentence. It was important to note that sentence pauses were a highly technical process that required constant practice and accumulation of experience to accurately divide the pauses of sentences.
