this book gives quite a few useful elements but is not quite complete, plugs too quickly fly over the different translation problems (eg the chapter "you need / do not translate" just a few examples, we would have liked a more complete list and a slightly deeper examination of the subject ... and it's the same for each chapter and translation problem addressed) .Deuxièmement, corrected are not provided during exercises and "reflection subjects" .J 'I really felt that this book was more designed for use "accompanied" in progress, with the contribution of a professseur ... and not at all for a solitary study at home.
