От издателя:Oxford Practice Grammar Intermediate is divided into units, each of which covers an important grammar topic. Each unit starts with an explanation of the grammar and is followed by a set of practice exercises. It's a really flexible course too - you can either start at the beginning and work through to the end or choose the order in which you want to study the grammar topics - perhaps starting with those that are giving you problems.
