Dear Mrs. Green,

I'm writing to let you to know that I can’t attend class for the following week because I’ve had accident and hurt my back.

I take medicine for the pain, but I can’t get up and walk around much. The doctor said I should stayed in bed and rest as much as possibly. I hope to be back in class in May 12th. Until then, I think I will be studied at home.Could you tell me the learning tasks and assignments I need to finish during this time such that I can try to catch up with my classmate?

Thank you for you understanding.

Yours sincerely,
