My name is Lan. I study at a middle school in Hanoi. I usually get up at half past five in the morning.I have breakfast at a quarter past six and go to school at half past six. At school I study nine subjects, and Math and English are my favorite subjects. I think they are very intersting. In the afternoon, we stay at school and do more exercises in all subjects. We also play football & volleyball in the school yard. We sometimes go to school libraryto borrow books.
