Dear Professor Johnson,

With this letter I'm introducing you Miss Yang Li, the daughter of my friend Mr. Yang. Miss Yang is planning the TOEFL in preparation to study in the United States. I would like to to provide some suggestion and instruction to help Miss Yang to improve her listening English. I will make sure that your efforts will be appreciated and that you will be considered favorably by the Dean of your Department.

Sincerely,
Zhang Bo
