How I spent my summer holidaysКак я провёл летоMy name is Andrey. I’m twelve years old. My favourite season is summer. My holidays began and it’s not necessary to wake up early and go to school. In June of this year I had a rest in the sports training camp. The time I spent there was very interesting and joyous. I made new friends and learnt much. We played football and volleyball. We were taught how to condition us to the cold. We had a shower bath every morning. When my father saw me he said that I’d grown up. In July I spent time with my grandmother and grandfather in their village. My grandfather went fishing and to the forest to gather mushrooms and berries with me. He taught me how to recognize edible mushrooms and orientate in the forest. I helped my grandmother with housekeeping every day. In the evenings I read books or went for a walk with my friends. In August my parents took a month’s holiday and we went to have a rest to the South together. Every day we sunbathed and swam in the sea. The weather was wonderful. We went to watch waterfalls and we were at lake in mountains. I spent my summer well and I was full of impressions.
