There are 100 units in the book. Each one looks at a particular area of grammar. Some sections within each unit focus on the particular use of a grammatical pattern, such as wilt be + -ing (as in will be traveling). Others explore grammatical contrasts, such as whether to use would or used to to report past events, or when we use except or except for. The 100 units are grouped under a number of headings such as Tenses and The future. You can rind details of this in the Contents pages.
