   Understanding and Using English Grammar is a high-intermediate to advanced level ESL/EFL developmental skills text. In the experience of most classroom teachers, language learners appreciate spending at least some time on grammar with a teacher to help them. For most English language learners, grammar remains the basis of their experience of English. The process of looking at and practicing grammar becomes a springboard for expanding the learners’ abilities in speaking, writing, listening, and reading.

There are numerous "real communication" opportunities for the teacher to exploit.
