Improve presentation

I think that presentation is a kind of communication that share the information. You need to explain easily so that everyone can understand. There are some ways to communicate. you should speech loudly, slowly and understandingly.Difficult words should be added explanation. Eye contact is very important, because you can find whether or not everyone are understanding. You should organize the main ideas and use pictures, computer, actions, movie, and music. I think that if you use these ways you will be able to attract audience. And I have to fix my habit that my eyes close automatically.
