The exercises in this book are designed to give intermediate grade students (say Cambridge First Certificate level) practice in the essential tenses in their essential uses. This does not mean that students will not come across other tenses in their reading: they probably will, and will understand their meaning (possibly after the teacher has done some explaining) without much difficulty. But they will not learn how to use them at this stage, which demands skill in the more usual tenses and uses.
