    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(xiàn)在頭很疼而且感覺很難受。我覺得我必須得請假去醫(yī)院看醫(yī)生。我會準(zhǔn)時參加明天的課。
    Yours repectful,
    Tim
