Challenger in the public speaking.

Every people if give the opportunities to do public speaking or not, most can not do that because it is very embarrassing. It is the big task to speak in front of public especially in English. But for me who like the challenger accepted this task with the calm. In this semester i have a big task to do it is i must complete seven of public speaking such as forum, persuasive speech, in front to speech and group discussion.
All this public speaking i and all student Eng 276 must speak in English. It make me a little bit scare and nervous. Before i do the public speaking lot of preparation i do especially practice to speak in English. I afraid i can not speak smoothly in English and the listener do not understand what i want to say. I think not only me feeling like this because every person feel nervous and not confident. As a student who no has a skilled to speak in English it hard to communicate with audience but i try to speak using the easy word to make them understand. Also the normal happen while performing public speaking, if too nervous the effect is what i prepare can not remember. Beside that i afraid too if my friend laugh while i speaking. Because their laugh to me maybe they saw i nervous and talk with broken English. The other challenger is when saw a friends doing public speaking and felt they were better than i. I think this is my challenger before, during and after do the public speaking.
