Modal Verbs

Modal verbs are an integral part of the English Language and without a good understanding of how to use modal verbs correctly, it's not possible to read, write, speak or understand English at an advanced level or to pass advanced-level English examinations such as IELTS.
This book is aimed at intermediate and advanced-level learners of English as a Foreign Language and IELTS student, as a reference book for English tutors and for Business English students.
