Dear Mary,
Thank you for your letter. You asked me to tell you about my trip to St.Petersburg in summer. I went there with my family. We stayed in a nice hotel in the city centre. Luckily the weather was fine and we had long walks around the city.
We did a lot of sightseeing. We visited Hermitage and Russian Museum, because my mother is fond of arts. Personally I found the ship 'Avrora' the most exciting place. I had read much about it and was happy to see it with my own eyes. The city impressed me really!
Well, I must go now. My Mom wants me to help her.
Write back soon.
Best wishes,
......
