Thirty Days to Better English: Learn to Speak and Write More Effectively--in Only Fifteen Minutes a Day!

Thanks for this great Book. I first knew this book at Berlitz and once got it, I realize that is really useful for all English learner. Thanks a lot Indeed.

I personally prefer Lewis' "Word Power" books, but I've noticed students do not stay with them--due to the length as well as piling on of information, especially etymological details. The present volume, on the other hand, represents an optimal compromise between comprehensiveness and depth. Lewis' progressive exercises help motivate the reader and provide a sense of accomplishment. Recommended for anyone who wishes to sharpen grammatical and vocabulary skills. Moreover, Lewis shows sufficient awareness of the differences between "prescriptive" and "descriptive" usage to be acceptable to traditionalist as well as modern grammarians.
