Looking back to the National English Speaking Competition I take part in several days ago, I have a lot to share to you.

Firstly, I feel real delighted that I’ve won the first prize in the competition, which makes me to understand the true meaning of the proverb “No pains, no gains”. Besides, I’ve established the friendship with students from all over our country, from which I’ve learned a lot. More importantly, participate in this competition has enabled me to overcome my fear of speaking in public, thus developing my self-confidence. Additionally, I owe much thanks to my teachers and judges. Without his help, I couldn’t have done such excellent job.

To sum up, I will always treasure this meaningful and memorable experiences.
