Перевод(желательно не через переводчик) My home settlement is taracovka. Tarasovka is situated in the northwest of Rostov Region. It was founded in 1822. More that 11,500 people live in Tarasovka. Tarasovka is located on the river Glubokaya. You can see a bridge over the river. The first bridge was made of wood and rebuilt in 1960s. Not far from the bridge there is a nice old church. People and their families come there on Sundays. In the centre of the settlement there is a aquare. It’s a popular place. People come there on holidays to have fun. Concerts and festivals with traditional Cossack dances and songs are held there. The streets run from the central square. They are long but not wide. There is a railway station and a bus station in Tarasovka. Not far from the bus station you can find a bank, There is also o alrge marker, 0a department store and several small shops. There is a cinema in Tarasovka. A big park was planted by pioneers about 50 years ago. 10 years later a modern school was build in the middle of the park. The new hospital was opened in 1989. You can visit a monument to the Motherland and a famous monument to the Heroes of the Great Ratreotic War. Tarasovka is good place to live in. The people are friendly.
