there is a gap between the English that is needed by the learner and the proposal of many English books.

books are important didactic tools because they select the English that should be taught: polite, legitimate and real.

English teachers know that standard English shows a model that should be followed by the learner.

standard English should be adopted by teachers as a way to provide the students with a model of communication.

by learning standard English students are given the opportunity to belong to a world to which they would not be able to belong.
