This is a preposition and adverb workbook you can work on at home or use in classes. This is the book I wrote for my own students for my ESL classes overseas. Packed with over 200 pages of information, quizzes, worksheets and more! There are books on idioms-expressions-sayings-slang, prepositions and adverbs, verbs and adjectives, comparatives and superlatives as well as an ESL workbook that have been released.
