（Zhang Xin) is my friend.对括号里的部分提问

Dear Mike,
I am Zhang Xin. I learned you want to be pen friend with a Chinese student. I am 14 years old and now studying in a middle school. In my spare time, I often go swimming, go fishing and playing basketball. I like listening to music, too. I’d like to be your friend.
I am looking forward to your reply.
Sincerely yours,
Zhang Xin
