This book is not an extensive manual, so the result is a basic and straightforward handbook. Obviously, it is just an initial reference that may be used in the two levels of Spanish post- compulsory secondary Education (Bachillerato). Even, it can be used in the first years at the University (Magisterio por Inglés, Filología Inglesa), in order to have a first contact with some of the grammatical components of English Language. It is not intended for students that are studying CAE or Proficiency levels, as long as it is not as specific as it should be in those levels. The practical nature of the book should be emphasized, as it is felt that it will give many opportunities for discussion of morphosyntactic structures.
