Cambridge English Grammar In Use Intermediate incl Answers

There are 136 units in the book. Each unit concentrates on a particular point of grammar. Some problems (for example, the present perfect or the use of tbe) are covered in more than one unit. For a list of units, see the Contents at the beginning of the book. Each unit consists of two facing pages. On the left there are explanations and examples; on the right there are exercises. At the back of the book there is a Key for you to check your answers to the exercises (page 310).
