In writing inglés IV, i have kept in mind the goals put forth by the programa de estudio del colegio de bachilleres del esto de veracruz. This program specifies the instructor?s role as being the following: To this end, I have attempeted to present the eight structures required in 4th semester english in the clearest and most entertaining way. My hope is that the student will consider inglés IV an accesible text and not it intimidating. With regard the way structures are presented, I have also followed the programa de estudio, which puts forth that. Susch specifications allow for the inclusion of brief explanations without weighing the student down with lengthy grammatical rules. We may ask ourselves wath role grmmar plays in language acquisitions. It is a word which makes most student shudder, but the truth is that the existence of such rules facilitates both teaching and learning.
