英文道歉信格式及范文

因迟复来信致歉Because of answering one’s letter late

Dear David:

I am afraid that you will think me unpardonably negligent in not having answered your letter dated 7， December sooner， but when I have told you the reason， I trust you will be convinced that the neglect was excusable。 When your letter arrived， I was just in Hong Kong。 As my family could not forward it to me during my absence， it has been， therefore， lying on my desk until the moment when I took it up。 Now the first thing I have to hasten to do is to write to you these few lines to express my deep regret。 

I enjoyed many pleasant sights during my trip。 I shall be pleased to give you an account to of them when I see you next。 

Sincerely yours， 

Tom
