假设你叫tom，你昨天在学校游泳池游泳患了感冒，今天早上觉得头疼，你母亲给你量了体温后，发现你发烧，便带你去看医生，医生说你需要卧床休息两天，特向老师请假。给老师写一张70—100字的请假条

dear sir,
i'm sorry to tell you that i can't go to school today, i've caught a cold because i swam in the school's swimming pool yesterday.
this morning i had a headache. after taking my temperature, my mother found that i had a high fever, immediately she took me to see a doctor, who advised me to stay in bed for 2 days. now i am writing to you to ask for 2 days' sick leave.
with best wishes
