Twenty but One

Twenty-one, now renewed for the second time, has been expanded with thematic, B1- and B2-level dialogues and situational tasks in English, retaining the collection of words and phrases absolutely necessary for each topic, as well as monologues and series of questions related to each topic. By increasing the amount of B1 and B2 material, and for other reasons, the higher C1 level was removed from the book - this space is described in Another step forward. loaded by our publication. We have removed previous grammar exercises from the book, but it has not been deleted from the title page, so we apologize.
