Speech contest

I'm thinking of applying for an English speech contest. In the contest, I'll be asked to talk about Hong Kong, especially about its tourism. I'd like to participate in it, because it would be helpful to improve my English.

To tell the truth, I haven't joined this kind of contest. What is it like to speak in front of hundreds of people? I respect President Obama. His speech in Chicago was so nice and moving. After I listened to his speech, I felt the strengths of the U.S.



I think I will apply for the speech contest for sure. Even if I can't win a prize, I believe I'll be glad I made this decision.

If you're familiar with how to give a good speech, would you tell me about it please?:)
