1000 TRIOS is an invaluable tool for students preparing for the Cambridge CAE and CPE exams. It helps them gain extra confidence in dealing with the gapped sentences, the exercise that is part of the Use of English Paper in the Cambridge Advanced and Proficiency exams. A typical self-study book for advanced students contains about 25 sets (each with three sentences). This book provides 40 times more - 1000. Consequently, it gives students an unprecedented opportunity to polish their skills. 1000 TRIOS will also satisfy the needs of all those who love playing with the English language. It offers an intellectual challenge and hours of great fun while trying to work out the answers.
