Dear Sir，Please excuse my absence from class today， because I got a bad cold yesterday evening and didn‘t well in the night. I felt even worse this morning. Therefore， I had to go to the doctor to have myself thoroughtly examined. Thus， I am writing to ask you for a day‘s sick leave and assure that I‘ll resume my study if I feel any better tomorrow. Sincerely
