Dear teacher，
Words fail me when I want to express my thanks to you. You have taken good care of me since I came to this school. When I am in trouble，you always encourage me and cheer me up. You are kind but strict with us，you never allow us to pretend that we know what we don't know. You often tell us that it's no use memorizing new words without understanding. With your help，my English has greatly improved. Thank you for caring about me，I will work harder in the future。
Best wishes。
Yours，
