Dear teacher x:
Hello!
Time flies. I am already a junior student in a twinkling of an eye. As a class teacher in our class, I appreciate your concern and concern for me in the past three years. In the past three years, you have worked hard and paid a lot for us, and you have also been conscientious in class for us, hoping to give us all you know.
In order to show my gratitude to you, I would like to invite you to dinner. I wonder if you have time next week at 12: 00 noon. Location: XX canteen of the school. Looking forward to your reply!
with the best wishes
Salute
Your student: XXX
