Understanding and Using English Grammar is a high-intermediate to advanced level ESL/EFL developmental skills text. In the experience of many classroom teachers, language learners like to spend at least some time on grammar with a teacher to help them. The process of looking at and practicing grammar becomes a springboard for expanding the learners´ abilities in speaking, writing, listening, and reading. Most students find it helpful to have special time set aside in their English curriculum to focus on grammar. Students generally have many questions about English grammar and appreciate the opportunity to work with a text and teacher to make sense out of the sometimes confusing array of forms and usages in this strange language. These understandings provide the basis for advances in usage ability as students experiment, both in speaking and writing, with ways to communicate their ideas in a new language. Teaching grammar does not mean lecturing on grammatical patterns and terminology. It does not mean bestowing knowledge and being an arbiter of correctness. Teaching grammar is the art of helping students make sense, little by little, of a huge, puzzling construct, and engaging them in various activities that enhance usage abilities in all skill areas and promote easy, confident communication. The text depends upon a partnership with a teacher; it is the teacher who animates and directs the students´ language learning experiences. In practical terms, the aim of the text is to support you, the teacher, by providing a wealth and variety of material for you to adapt to your individual teaching situation. Using grammar as a base to promote overall English usage ability, teacher and text can engage students in interesting discourse, challenge their minds and skills, and intrigue them with the power of language as well as the need for accuracy to create understanding among people.
