According to the subject classification and mood type, the original text can be analyzed from the sentence level to obtain an accurate translation. Studying the thematic progression mode is conducive to the translator’s understanding of the structure of the original text and the distribution of information, the right remedy, the proper construction of the text of the translation, and the realization of the equivalence at the chapter level.
