兩封信告訴你 正式與非正式英文有何不同

下面有2封英文書(shū)信，你能分辨哪封是正式信件，哪封是非正式的嗎？

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 gate and 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
