Dear Miss Gao,
I can't go to school today because I had my leg hurt.
Yesterday our class went to the farm to help the farmers pick apples.Unluckily I fell off the tree and hurt my leg.The doctor checked and asked me to stay at home for a few days.
So I'm writing to ask you for two days' sick leave.
Hope for your permission.
Your student
