5 Bolshaya Lubyanka Street St Moscow 10 September 2010 Dear Michael, Thanks for your letter. It was great to hear from you. In your letter you asked me about my summer holidays. Well, I had a very good time! In June I stayed at home because I had exams at school. Luckily the weather was nice and warm and at the weekend my parents and I went to our country house. We went sunbathing and swimming in the lake near there. In July I went to a summer camp. To be honest, it seems fantastic to me. I made a lot of new friends. Every day we went swimming in the river, and we played different games. There was a disco every night. Once we went hiking in the forest for two days. We cooked our meals on the fire and at night we sat around the fire, sang songs and told stories. Are you happy with your new house? Is it bigger than your old house? Have you got a room of your own? Please tell me more about it. I am looking forward to receive your letter. Best regards, Tanya Какие недостатки и ошибки есть у этого письма? Правильно ли раставлены знаки препинания?
