If the contents of the publicly released book are arranged into PPT for fee training, will it infringe the copyright of the author of the original book?

Possible infringement depends on the form used in ppt. If you just apply the author's point of view and add your own frame structure, then you use the author's idea and don't infringe copyright. If the form used in PPT is simple and rude, then the expression of the original author is used, which constitutes infringement.
