Popis Callan Method - St.5 - 2013 Edition
Stage 5 is for learners at the start of their intermediate level studies. In addition to containing much vocabulary appropriate for this level, Stage 5 covers a number of demanding areas of grammar. These include the past continuous (e.g. "I was sleeping"), the passive voice (e.g. "the book was written"), reflexive pronouns ("myself", "herself" etc.), the past perfect (e.g. "you had studied"), the future continuous (e.g. "she will be working") and the 3rd conditional (e.g. "If you had gone …, you would have seen …"). This stage is appropriate for learners at B1 level according to the CEFR, although it does contain some grammatical forms appropriate for B2 learners as well.
