Dear Wei Fang,
I hear that you have won first prize in the English Speech Contest of Middle School Students, so I’m writing to give my sincere congratulations.
You don’t know how excited I was when I heard the good news. As your best friend, I am proud of you! Your pronunciation and fluent English left me with deep impression. It came as no surprise to me that you won the contest. Could you share with me how you improve your spoken English? Your experience will be of great help to me in learning English.
I will be grateful if you can write me back and give me your advice. I am looking forward to your early reply.
