　　Dear Tom,

　　It's great to receive your e-mail. Now I'd like to tell you something that took place in my school yesterday.

　　In the afternoon we held a grown-up ceremony for our coming 18-year-old birthday. At first we made an oath that as grown-ups we should have a sense of duty/responsibility for our society from now on. Then we showed our thanks to our parents who had gone through hardships to bring us up and teachers who have been educating us patiently. And our teachers also gave us cards expressing their good wishes to us. Finally we put on wonderful performances, singing and dancing. We learned a lot from the activity. I think it's very important for us. I will never forget the day in my life.

　　Yours truly,

　　Li Hua
