One possible version:

　　Hi, everybody!

　　I’d like to tell you something about myself. I’m Jeremy, a 16-year-old student from China, Asia. To experience a different senior life, I come here. I like the school, for its beautiful buildings and friendly teachers and students. I still have some difficulties speaking and listening to English, so I hope you can help me out. You are the ones I’d usually like to turn to when I’m in trouble. I haven’t had any friends or relatives here, but I do hope we can be good friends. I like drawing, and I hope there’ll be art time for me every week.

　　That’s all, thanks!
