The primary function of the Pre-Intermediate level is to address the "intermediate plateau"—that frustrating phase where learners know basic structures but struggle to express complex thoughts or understand native speakers fluently. New English File Pre-Intermediate tackles this by systematically expanding a student’s lexical and grammatical range. The book is divided into manageable files (typically nine to twelve), each centered on a high-interest theme such as travel, work, culture, or relationships. Each file integrates four key skills—reading, writing, listening, and speaking—around a core grammatical point and a set of practical vocabulary.
