Congratulations on winning the speech contest, Peter!
Thank you.
Could you tell me some important factors in delivering a successful speech?
Well, basically 4 points. Pronunciation, intonation, a well written essay and proper body language.
But how do you use body language properly?
The key point is that body language should be a natural aid to the ideas you express. Don't use body language simply because you think you should do so.
I see. By the way, how do you benefit from such an experience?
A lot! this public performance tests my English, strengthens my confidence and may bring me more opportunities.
