I'm so exciting that our drama club won the first prize in this competition. Participating in this club help us to learn more about drama, but develop our self-confidence and cultural qualities as well. Besides, thanks for the club, I have known many friends who share the same interest with myself. There we communicate and learn from each other. Before the competition we keep on practicing for long time. Luckily, our efforts were paid off, what is beyond our expectation.
Finally, I'd like to express my thanks to all of our teachers who directed us, friends who helped us, and partners who worked hardly. Thank you for all your kindness.
