The function of this book is to enhance the English proficiency of non-native speakers, while at the same time introducing them to some distinctive aspects of the American background. This approach serves the purpose of helping to adapt them both to the language and to the environment.
This language material is designed so as to help students to apply what they have learned to their own speech and writing. In addition, turns-of-phrase and idioms as well as vocabulary are presented in such a manner as to alert students to connotations and to considerations of the situational appropriateness of a word, a pattern, or a particular expression.
