Dear teacher x, hello:

I have been a monitor for n years. With the care and help of my classmates and teachers, I not only learned to do my job well, but also gained social experience ... all aspects benefited a lot. Thank you!

Because of XXXXXXX (or I am not suitable for the position of monitor, I am not good at it, etc.), I think other classmates will do better than me.

I am here to convey

welcome

My name
