Hello everyone! I'm glad to be with you today. Welcome Mr. (Mrs.) xx (foreign teacher's name, please be friendly first) to our class. I am xx, from xx. Like all boys, I like basketball and making friends. Although we are not familiar with each other yet, I believe we will become good friends soon.

In this holiday, I think the most important thing that happened around us is the Beijing Olympic Games. It really drives me crazy to see us China people doing so well. I bet this is the greatest Olympic Games in history.

Finally, I hope we will have a good time in the next three years.

Thank you.

I don't know whether you are going to college or high school, but I think this level is just right. Foreigners pay attention to understanding each other when communicating, and the dialogue is interactive. So I suggest you be generous and natural when introducing yourself, and be sure to give him some eye contact, which is very important! Talking nonsense with him about other things can make you more different, and after listening to so many similar introductions, he will be impressed by your nonsense.

Good luck!
