Now I want to tell you about my native city Volgograd. It’s very large and the most beautiful city I have ever seen. I really enjoy the Museum - panorama, where a guide tells everybody about Stalingrad Battle. It is very interesting and unforgettable. We ride a boat along the great Russian river the Volga. There is a famous Mamaev Kurgan and a beautiful embankment in Volgograd. There are many cinemas and theatres in my city too. The hotel "Volgograd" is one of the most beautiful hotel of the city.  Jor city is worse visiting. Come to my place and see how amazing it is. We’ll walk or ride a bus round the city to see all the attractions and sightseeing.
