A presentation is a formal talk to one or more people that "presents" ideas or information in a clear, structured way. People are sometimes afraid of speaking in public, but if you follow a few simple rules, giving a presentation is actually very easy. This tutorial guides you through each stage of giving a presentation in English, from the initial preparation to the conclusion and questions and answers. This tutorial is itself set out like a mini-presentation. You can follow it logically by starting at the Introduction and then clicking on the link at the foot of each page, or you can jump direct to the section you want from the list of contents on each page.
