This is an upgraded version of all of our previous Focus on English grammar content together in one book. This brand new edition has been designed to help the student to quickly find answers to English grammar questions about: prepositions, phrasal verbs, idioms and expressions, English irregular verbs, English expressions for real life (advanced ESL), gerunds and infinitives, and English articles (a, an, and the). These are the six English hot spots (difficult areas) made manageable for ESL learners. The book was especially created for fast searches of topics of importance to the student, with many examples of correct usage plus many exercises to help the student practice. This book is for intermediate through advanced English/ESL learners and a quick reference resource for students studying for TOEFL, TOEIC, and Cambridge exams, and second language students studying for their GED exam.
