七、One possible version:
How is everything going? I'd like to introduce my best friend, Tian Tian, to you. She is 16 years old. She is a lovely girl with a round face and big eyes. She is very kind and easy to get along with. She likes reading and listening to music, and she is especially good at playing the piano. Her favorite subject is English.
Now she is going to George Spencer School in England to study for one year. I hope you can be good friends. She is arriving at Heathrow Airport at 4 pm on Aug.1st.
