The purpose of this textbook is to help students master both translation skills and skills in oral and written English. To achieve this goal, students must acquire a certain vocabulary and study the grammatical structure of the language. Since the student thinks in his native language, the close interaction of his native and foreign languages in the learning process plays an exceptional role. The authors sought to note both the difference between grammatical phenomena in both languages, as well as their similarities. Considering that students strive to transfer constructions characteristic of the Russian language into foreign speech, the authors make appropriate warnings in a number of sections in order to prevent typical errors arising on this basis. The authors sought to rely as much as possible in the presentation of grammatical phenomena on students’ knowledge of the Russian language, using definitions , formulations and terminology from Russian grammar, deviating from this in cases where the specifics of the English language required it. In terms of its volume, this textbook is close to standard grammar textbooks for language universities. However, it differs from them mainly in a less detailed theoretical analysis of grammatical phenomena, since it is intended not for the training of teachers of the English language, but for the training of specialists involved in their practical work with the English language. The textbook covers the main grammatical phenomena encountered both in everyday life and business colloquial speech, as well as in economic and foreign trade texts and documents, since the textbook is primarily intended for educational institutions of the Ministry of Foreign Trade. Some sections, such as participle, infinitive and gerund, are developed in somewhat more detail than other sections, since their detailed study is especially important for the accurate translation of special texts and documents. Examples illustrating grammatical phenomena, and many exercises are based not only on everyday vocabulary, but also on the most commonly used political, economic and foreign trade vocabulary.
