　　Dear Mrs Brown，

　　My grandma suddenly fell ill last night. My parents happened to be out on business. I had to send her to hospital and look after her. I 'm writing to ask for leave of absence for three days.

　　I shall be very grateful if you will grant me my leave. I '11 try my best to make up my lessons missed during my absence as soon as I get back from leave.

　　Yours sincerely，

　　Lucy
