信件1：
Dear Sir or Madam,
I am writing with regard to a ?ight that I missed due to a mistake by one of your employees.
Two weeks ago I was due to catch a ?ight to Rome, where I intended to spend four days on holiday. Unfortunately, the attendant at the check-in desk gave me a boarding card for a different ?ight, and I did not notice the mistake until I arrived at the departure gateand it was too late.
As a result of the error, I was not allowed to board the ?ight to Rome, and this caused me great inconvenience. I had to book a new ?ight two days later, which meant that I missed two days of my holiday and I spent an extra ￡200.
As the mistake was caused by your company, I hope that you will compensate me for the cost of the additional ?ight, as well as for my taxi fares to and from the airport.
I look forward to receiving your response.
Yours faithfully,
Paul Jones
信件2：
Dear John,
I’m just writing to let you know that I’ve moved house.
As you know, I went for an interview for a job here in London. Well, they gave me the position! It would have been impractical to travel down from Manchester every day, so we’ve found a house here, in a nice part of London called Greenwich.
Our new house isn't ideal. London prices are crazy, and we were only able to afford a one-bedroom ?at. But on the bright side, it’s on the ground ?oor, it’s got nice big windows, and a lovely view out onto the garden.
If you ever fancy a trip to London, you’re more than welcome to come and stay. It would be great to see you. From where we live, it’s only a quick ride on the underground into the city centre, so we could do some sight-seeing together.
Keep in touch!
All the best
Mike
