Dear teachers and friends,I'd like to say something before Tracy goes back to England.Tracy is a very
kind and friendly girl and I feel happy to be her friend.She gets along well with everyone and all of us have
a wonderful time with her.Whenever we have trouble learning English,she doesn't hesitate to help us and
our English has been improved a lot since she came to our class.We owe a lot of thanks to Tracy.
True friendship never ends,so I hope we can keep in touch with Tracy.I also hope that Tracy can come
back to China and stay with us in the near future.
That's all.Thank you.
