The dialogues and stories present the basic grammatical or syntactic phenomenon. The details that, in the teacher's judgment, students must definitely know are included in the exercise book. 

The drawback that could be attributed to the book, and which we also acknowledge, is that not all the dialogues are interesting, they do not cover all possible communicative needs, and of course, they are not grouped according to the various situations they present. 

However, it becomes easily understandable how difficult it is to write a book in a way that fully serves both grammar and communicative situations in a logical sequence. Nevertheless, it must be admitted that students are given the opportunity to create, to get to know various situations, such as housing, origin, studies, stay in a foreign country, occupations, etc., and to practice grammar, not by tediously repeating drills or conjugating a noun, adjective, or verb, but by speaking.
