Let me introduce myself. My name Vlad and I’m 14 years old. I live in one of the largest and most beautiful cities in the world, in Moscow. My parents are both doctors, and they want to see me as a doctor in the future. We live in a three-bedroom flat on the outskirts of the city. My school is situated within a walking distance from our block of flats, but my parents take a subway to work every day, except weekends and holidays. We have a lovely country house in Podmoskovye. It’s the territory that surrounds Moscow. We usually spend weekends at this place. If we go by car, it takes us about two hours to get there. We all love the surrounding nature at that area. It’s simply wonderful. Our country house is situated next to the lake and the forest. In autumn my parents often pick mushrooms and berries in this forest. I prefer the summer weather. When it’s warm enough, I go swimming in the lake with my friends, who are also there for the weekend. Speaking about the structure of our house, I should mention that it’s a two-storey brick building with many windows and the front door. There are three bedrooms and a bathroom upstairs. There is a kitchen, a dining-room and a living-room downstairs. You can see vast expanses of land behind the house. My parents grow fruit and vegetables there. Each year, we have our own harvest of potatoes, cabbages, apples and pears. When it’s someone’s birthday, my father makes barbeque and we invite our friends and neighbors over. What I especially like about our country house and the area, where it is situated, is the peaceful atmosphere. There is neither city noise nor traffic jam. It’s one of the calmest and most beautiful places in Moscow region
