英语道歉信范文及常用句式
道歉信是指因过失或疏忽做错了事，给别人带来了麻烦或损失，发觉后要立即写信给对方赔礼道歉时写的信件。道歉是一种礼貌，道歉信要写得坦率，诚恳。
道歉信通常包括三部分内容：1、表示歉意，道歉的原由；2、出现差错的原因，提出弥补措施；3、请求原谅。语言要诚挚，解释的理由要真实。好的道歉信不仅会取得对方的谅解，还会增进彼此的感情。
写作"三步曲"：
表示歉意→说明具体原因、提出补救办法→再次致歉，希望得到理解。注意：
理由要尽量合理，违反生活常识将导致扣分；尽量提供一个合适的补救办法，使行文更加顺畅。

Dear Ms Winston,
The purpose of this is to convey to you my sincere apologies for any inconvenience you may have experience last month with respect to the installation of your Internet high speed service.
I just returned from vacation this week and found your file in my in-basket. As soon as I reviewed your case it was clear that somehow your Jau. 20th request for a change in service had somehow slipped through the cracks. The only possible explanation I can give is that we have recently had a number of key staff changes, which might have resulted in your letter being overlooked.
Consequently, I have directed our installation group to contact you by the end of this week to set up a time convenient to you when they could go to your house and install your new router and make the necessary adjustments to your software.
Because of this serious oversight, and as a testament to our appreciation of you as out customer , we are going to provide you with your first three months of high speed service for free charge. There fore, your account will not be billed until June of this year.
Ms. Winston, let me assure you that what happened in your case is not typical of CableNet’s level of customer service. We continue to be committed to providing you and all of our customers with the highest standards of service in the industry.
If you have any questions please don’t hesitate to call me at*******.
Yours in service
Tony
