The textbook is intended for teaching students in language high schools and specialized foreign language classes in secondary schools. The aim is to overcome the self-serving nature of language teaching in Bulgarian secondary schools and to improve students' linguistic, communicative, and sociocultural competence in both their native and foreign languages. In this regard, teachers are offered a variety of teaching techniques. The importance of the proposed program lies in its completeness, consistency, and clarity. The ultimate goal of the training is for students to avoid mistakes of any kind—semantic, lexical, and syntactic—when translating a text from English into Bulgarian.
