Unit 18 covers three grammar topics: modal verbs, passive voice and phrasal verbs. In each section, it is dedicated particular attention to the difficulties that both teachers and students might face with these subjects. In particular, if the toughness related to English modal verbs is understanding and explaining their many usages, the most difficult part of the passive voice is its structure. Speaking of phrasal verbs, it seems almost impossible to learn them only by using the memory. Providing lists of the most common phrasal verbs might be useful, but I believe the best way to acquire them is from real contests and real conversations.
