Last month, my English teacher asks
me to take a part in an English speaking competition. But I doubt that I
have the ability to win. It is known to all my classmates that I can
always speak English as good as a native speaker. However, I dare not
express my ideas, especially in public. My best friend Lisa has been
encouraging me accept the challenge.
On her opinion, as long as I try my
best, I will make it. After hear this, I have decided to have a try. I
hope I will be luck.
