Thank you for your letter. In summer I v/as in the country, too. In June my mum took my brother and me to the Black Sea. The sea was blue and nice. The weather was sunny and hot. We swam and dived a lot. We saw dolphins in the sea.They were big and strong. I think dolphins are the nicest animals in the sea.In July I went to the country with my grandma. We lived on the farm. There were many green fields and a long river next to our farm. There was a green garden with apple trees behind our house. In the morning I fed hens and ducks. Then I rode a horse in the fields. I saw a lot of cows and sheep there. I like to live in the country.In August my dad and I went to Moscow. It's the capital of Russia. It's thebiggest city in our country. The streets are wide and long in Moscow. There are lots of people, cars and tall houses. One day we visited the most interesting place in Moscow — the zoo. We saw many different animals: eagles, camels, monkeys, elephants, tigers, bears and a giraffe Samson. I spent (провёл) five days in Moscow. And I was glad to come back home. Now I know "East or West home is best!" I like my friends and my old green town — Kaluga.Would you like to visit Kaluga next summer? We'll have a good time together'Write back.Your friend, Dima Sokolov
