Description: If you know 500 English words, then these books are for you. The first book uses a vocabulary of only about 500 words, and the other books increase it by 300 or 400 each. Including the words you can learn from the clues, your vocabulary at the end of the fourth book will be in the 2000-word range. Work out the puzzles, and you can:
* Revise the words already learnt, and learn many more
* Learn the correct spelling of unfamiliar words
* Learn how to use new words in sentences
* Learn new words with the same or opposite meaning
* Practise thinking in English
