My Challenger In Public Speaking!!!!!!!

       Talk about the challenges of public speaking is a lot of challenges that need to be me and all my friends have to face before do presentation.Among the challenges that i can not forget when i need make impromtu.I had introduce what kind of thing that we get and talk about that in spontan.It so difficult because we must find the ideas very quickly to explain the thing that we get.Not everyone in this world knows well to speaking include me,when i need to speak in spontan at that time feel like i lost my life and blank.I confess that i was weak in english,everyone will laugh at me when i do not either want to say anything or not.I know at that time Madam will give vert lower mark to me and its will give  effects to my carry mark.Besides the most intense challenge is we have to compete with other friends,using a word that we have the power to attract listener and lecturer.Suddden we forget what to say but do not directly indicate the face nervous,trying to control the situation becomes calmer.
