Do not sign your own name at the end of the letter. Use “Li Ming” instead. You do not need write the address.

    正确答案：
    Dear Sir or Madam,
    After reading the news about your university holding a three-month English course for overseas students in the newspaper, I want to grasp the opportunity.
    I'm a 22-year-old college student. I'll graduate from Huaxing University in July next year. I have been learning English for six years. My spoken English is still not fluent enough although I can write in English quite well. I'm planning to go abroad after graduation but first of all I have to pass TOEFL and GRE tests. Therefore, I suppose attending your short-term training may help me improve my oral English. Will you please tell me the schedule of the course and the specific location of the classroom and also send me an application form if possible?
    I'll greatly appreciate it if I can take the chance.
    Sincerely,
    Li Ming
