Dear Tom,

　　It i s great to receive your email．Now I'd like tell you something which took place in my school ye sterday．In the afternoon we hold a grown-up ceremony for our coming 18 year s old birthday．At fir st we made an oath that a s grown-up, we should have a sen se of duty for our social from now on．Then we showed our thank s for our parent s who had gone through hard ship s to bring u s up and teacher s who have been educating u s patient．And our teacher s al so gave u s card s expre s sed their good wi she s to u s．Finally, we put on wonderful performance s, singing or dancing．We learned a lot from the activity．I think it' s very important for u s．I will remember a day in my life．
