Dear Sarah:
I want to write to you to express my thanks for your help in learning English. I’m glad to be your student, and I am very happy to learn English under your help. You are one of the best teachers . I know there are many good points what I should learn from you, such as kindness, patience, humor and so on. I know you are kind and helpful to me. You are not only a good teacher but our close friend. Thank you for helping us make something of my lives.
Many thanks to my tutor Sarah and advisor Alice.
Best Regards,
Winston
