Прошу вас помогите! С англиского на русский можно? Умоляю!!


It was great to get a letter from you.
Yes,
I like to travel and learn more about different places. And I also
travelled a lot this summer. In August I went abroad. I spent two weeks
in Cambridge in a summer school camp.
In the morning we spent three
hours learning English. In the lessons we read and discussed texts,
learned English poems by heart, played games, and used the computers. We
also read interesting stories about English history and traditions. We
took a lot of pictures and had fun. Now I speak, read and write English
much better than last year.
We also spent three days in London. It was great! When we go to England, I'd like to visit London again.
That's great that you like St Petersburg. I like it very much too.
Jim
says Barbara Grey is your English teacher. Fantastic! Last year she
taught us English too. She was my favourite teacher! I want to become an
English teacher like Barbara. Send my best regards to her.
Best wishes,
Lena.
