Dear Prof. Patent,
I am very sorry to inform you that I did not manage to complete the book report you assigned last week, due to a sudden illness falling upon me a few days ago. For the past few days I have been in hospital with a continuous fever, which has thus prevented me from any academic activity. I hereby submit the doctor's note.
I would be very much obliged if you could grant me another week for the task, as my health is turning better.
Hope you can understand my situation and accept my apology.
Yours faithfully,
Li Ming
Dear Sir or Madam,
I’m writing this letter to apologize to you. I’m so sorry that we made a mistake about the shipment of vacuum cleaners.
Those vacuum cleaners we sent to you were meant to be sent to European countries, but as the old worker was retired, the new one wasn’t so experienced. Besides, the model number and the price of goods in March and July are so similar that the worker mistaken them.
I am awfully sorry for this and we promise you a replacement shipment. We will also give a 10% discount to compensate.
I do apologize for any inconvenience this may cause you and I will try my best to avoid the same accident happening again.
Yours faithfully,
Dear Susan,
I’m very sorry that I was out when you came to see me yesterday evening. I’m afraid I’d gone to the pub with some friends and didn’t get back until 12 o’clock.
I wish I had known you were in Luoyang as you could have come with us. It would have been a good introduction to the night life! Anyway, I will call on you at 10 o’clock on Saturday morning at your hotel.
We can have the day together, if you have nothing else planned? I’ll show you some of the places of interest that you may not have seen.
Please let me know if you will be available on Saturday morning.
Best wishes
Chen Cheng
