英语口语比赛演讲稿,求大神修改润色
Good afternoon ladies and gentlemen!My English name is Stan .It is really my honor to have this opportunity for an interview.I hope I can make a good performance today.
I have been paying attention to English for many years and I am very interested in it .For me,learning English is an enjoyment.When I heard that I need to prepare for this competition,I was shocked and a little bit scared because I never joined any oral competition.I thought it was a hard thing to do.But I now believe that I should have a try and do my best.Someone said Nothing is difficult to a willing heart.Everybody should have the courage to catch the chance and hold on it.If we did not try ,how can we know that we can’t do it?That’s why I’m standing here.
Finally,I wanna thank my teacher who gave me the chance to join this activity.Thank you for your kind attention and have a nice afternoon.
