Dear Mr Li,
李老師:
I’m sorry to tell you that I have to ask for sick leave for the whole afternoon class. Because I have a heavy headache now and feel very sick. I think I have to ask for sick leave to go to hospital for medicine. I will attend the next day classes on time.
我很抱歉地告訴你,我想請一整個下午的病假。因為我現在頭很疼而且感覺很難受。我覺得我必須得請假去醫院看醫生。我會準時參加明天的課。
Yours repectful,
Tim
