写作
Dear Peter,
I’m writing to ask whether you are able to do me a favor.
I want to have a pen friend, hopefully an 18 year old girl, and with interests similar to mine. In my mind, she is someone who is interested in travelling, swimming, and playing football. Besides, it would be better for her to have a pet dog as I have kept one at home for some time. With such a pen friend, I hope I can share with her our experiences in travelling, taking care of pets, or whatever we have in common. And I believe I will improve my English by doing so and learn more about her country.
I am looking forward to hearing from you soon.
Best regard,
Li Hua
