COMPARATIVE ANALYSES OF ENGLISH TEXTBOOKS LEXICAL CONTENT (CASE OF STUDY TEXTBOOKS “UPSTREAM” SERIES)

Considering the significant role of textbooks as core information storage in the process of language acquisition, this study is focused on the comparative analysis of vocabulary content at levels B2 Intermediate, B2+ UpperIntermediate and C1 Advanced in “Upstream” series of English textbooks. The main purpose of this research is to analyze changes in the qualitative composition of the vocabulary for the topic “Travelling” from B2 Intermediate to C1 Advanced. Specifically, we aim to draw a parallel between the lexical content of the same topic at different levels of the “Upstream” textbook series in terms of morphology, semantics and structure of lexical units. Each level of English proficiency assumes certain qualitative and quantitative stock of words to be implemented by students. We examine such vocabulary components as idioms, fixed phrases, phrasal verbs, and thematic collocations at each level. Comparative analyses of idiomatic expressions and phrasal verbs display the absence of synonymy and at first glance low compliance with the subject, but it should be considered that context plays a big role. Topic “Travelling” is fully expressed in lots of words, terms, collocations which are presented to increase the students’ vocabulary. During the study we conclude that B2 consists of the main basic lexical units, the study of which cover the level requirements. Thematic content makes the B2+ level an extended version of the B2 and is intended to strengthen vocabulary skills. Advanced level is distinguished by the great attention to detail and nuances in terms of expressing thoughts fluently.
