Research based on stylistic markers provides an accurate method for describing language style, and the application of stylistic markers in English learning has gradually garnered attention from scholars. The analytical applications of stylistic markers in language are also pertinent to English language learning. This paper explores the use and differences of dialogue styles in both the original “Thunderstorm” and its English translation, starting from the formal and informal markers of stylistic markers. The analysis focuses on the properties of three categories of formal markers: syntax, vocabulary, and rhetoric, as well as the attributes of two categories of informal markers: the internal qualities of the work and the integration of the recipient’s perspective.
