Dear Barbara,
Thank you for your letter. It was so good to hear from you. I hope your return journey was OK.
I also travelled a lot this summer. In August Elena and I went adroad. We spent two weeks in Scotland at Summer School. We lived and studied at a good state school. Would you like to know what wedid there?
Well, in the morning we spent 3 hours learning English. In the lesson we read and discussed texts, learned English poems by heart, played gemes, asked and aswered questions, learned new words, used the computer and wrote our own fairy tales. But we didn;t translete into Russian at our lessons because our didn;t speak Russian. We also learned about English history and traditions.
Now we speak read English much detter then we did last year . I made a lot of friends in Scotland.
We also spent 3 days in London. I tried to call you but you were not in.
We are impressed by Great Britain and hope to visit it again.
Best wishes from us all.
Your "lazy kids".
Elena and Olga.
