Dear Meili,
I am your new pen friend. I am from New York and I am thirteen years old. My family name is Smith.
I am in Class Four Grade Seven at No. 1 Middle School in America. There are thirty-two students in my class. My favourite subject(科目) is English. Miss King is my English teacher. She is our good friend. We like her very much.
Welcome to visit our country(国家).
Yours,
Kate
