Dear Cindy，

    Thanks for your letter. I miss you very much. It's always nice to hear from you.

    Today is the last day of my exams(考试). The math exam is very difficult, but the other exams are easy. I'm waiting for the summer holiday now. I'm  very excited，because I am going to see you and to be with you again.

    I'm  going to spend my summer holiday in New York with my sister. So we can play together again. I will enjoy our time together. I'm  going to watch football games with you. I think we will have a good time.

    I'm  going to the supermarket later on(过一会儿). I'm  going to buy some presents for you. I  hope you will like them.

Yours，

Jim
