Dear Susan，
I’m glad to be your student， and I am very happy to learn the course I like best under your help。
English is an important tool， through which we can share it with the world。 I treasure the chance of learning English， and I enjoy the happiness from this course。
This Thursday is Thanksgiving Day。 On this special day， I want to express my deepest thanks to you!
Yours，
sincerely
