Abstract: The object of the research is the description type texts and narrative type texts of modern Russian authors. The object of the research is the signs of a 'new situation', 'change', 'sequential relationship', 'emergence of a new situaton' in perfect verbs used in texts of description and narrative types. The authors of the article analyze the principles that define such sign as the emergence of a new situation in description and narrative type texts. To discover its peculiarities, the sign of the emergence of a new situation in description type texts is analyzed depending on the following genre types: description of one's appearance or portrait, landscape, interior design or personality description. One of the main methods used by the authors is the semantic contextual analysis that is based on the analysis of semantic peculiarities of verb predicates in terms of description and narration as well as the method of linguistic observation and description of language factors. Functional semantic types of speech are still of great interest to researchers, thus the novelty of the research is caused by the fact that the authors describe peculiarities of semantic signs of verbal predicates at the textual level. In particular, the use of perfect verbs in description type texts and narrative type texts are still an understudied topic and the textual approach provides a better insight into their text-formation role. Depending on the logical conceptual attribution of a text, the authors define the role of semantic signs of perfect verbs. Based on the overall logical description method (synchronologeme), semantics of predicates, the change-in-state concept and change-in-situation concept and the emergence of a new situation, description type texts use a statal type perfect verbs and narration type texts use actional perfect verbs.
