英语作文道歉信的结尾需真诚表达歉意、提出弥补意愿，并礼貌请求原谅，常用句式如“I hope you can accept my apologies”或“Once again, I am sorry for any inconvenience caused”。

1. 核心句式示例

   • 直接道歉：“Please allow me to say sorry again.” 适用于重复致歉的场景。
   • 表达弥补意愿：“I would be grateful if you could tell me how to make up for it.” 体现解决问题的诚意。
   • 强调歉意：“I am very ashamed of myself and hope you will forgive me.” 适合因严重疏忽导致的错误。

2. 适用场景与变体

   • 正式场合（如商务信函）：使用*“I do apologize for any inconvenience this may cause you.”*
   • 日常失误（如忘记归还物品）：可搭配*“Would you please excuse my neglect...?”* 显得更自然。

3. 结构建议
   结尾段需简短，避免冗长。先总结错误，再致歉，最后请求谅解，例如：“To be frank, I completely forgot about it. I sincerely apologize and hope for your forgiveness.”

掌握这些表达能提升道歉信的得体性，关键在于语气真挚、用词恰当。
