Dear Mary,

I'm happy to be your new e-friend. My name is Bob. I'm from America, but now I live in Canada. I have short yellow hair.

I live with my family in a big flat(公寓). There are four people in my family: my father, my mother, my sister and me. My father is a businessman. He often goes to other countries by plane. My mother is a teacher. She works in a school. I'm a student. My favourite subject is Science. My dream is to be a scientist(科学家) . I like reading. I always read science books. I also like doing sports. My favourite sport is football and I'm very good at it. My sister Alice likes drawing pictures and dancing. I go to school by bike, but Alice walks to school. Please write back soon and tell me about yourself.

Yours,

Bob
