Dear David,
Thanks for your email. And thank you for (introduce) your Chinese friend Lily to me. l know you are the class monitor. You can get on well your classmates. You are very kind and you are always ready (help) others. That's good. Work hard! Try to help (you) classmates when you are at school.
This term my classmates choose me the PE monitor in our class. do they choose me? That's because I run very (fast). My PE teacher and my classmates like me so much. They also want me (start) a PE club. I think that is good idea. We can play basketball or football in the club at weekends.
Please send some of your (photo) to me.
Yours,
Mike
