我不明白你的第二个要求，所以只写了上面一点，如有错误，还请改正。^_^

用英文写一篇请假条

英文的请假条要按照西方语言文化的排序。直接说明请假的原因。

例如：内容:你是学生,向陈请假,告诉她,你昨天在学校游泳池游泳,今早头痛发高烧,医生说你需要卧床休息三天。

Dear Chen，
Ive caught a headache and fever this morning that I was swimming in the school swimming pool yesterday.  
The doctor said I need to stay in bed for three days, so Im afraid in the following three days I will have to be abscent from the class. 
But I will get back to school as soon as I recover from my illness.  
Thanks for your kindness.
