紧急求助英语帝!麻烦高人帮忙将以下内容翻译成英文,要求语气礼貌委婉.我对我的缺课表示歉意,我缺课的原因是那天我发烧了,由

Sorry for my absence, but I had a fever that day. Since it is an accidental event, I couldn't make a notification in advance and have to email an explaination of the situation to my teacher.
I can't provide a written medical proof stating my health condition since I take pills instead of going to a doctor. Although my roomate can testify me in this issue, it is totally my mistake of violating the rules you have told us before this semester of how to apply for a leave. But please believe me that it will only happen once and you can have my word of not ever disobeying. Sincerely thank you for your remind!
其实不用说的太谦卑,只要清清楚楚把事情说明白就可以,以平淡和承认错误的语气说明就可以,又不是拐弯抹角问女生喜不喜欢你,这样不会显得你的情况说明做作.
专业回答,不懂再问,希望采纳,万分感谢!
