The Russian Federation is one of the largest countries in the world. It occupies about one seventh part of dry land.It is situated in Europe and Asia. The total area is over 17 million square kilometers. The country is washed by 12 seas and 3 oceans: the Pacific, the Arctic and the Atlantic.Russia borders on many countries such as China, Mongolia, Korea, Kazakhstan,Georgia, Azerbaijan, the Ukraine, Belorussia, Norway, Finland, the Baltic States.The country has steppes, plains, forests, tundra, taiga, highlands and deserts. The Urals, a mountain chain, separates Europe from Asia.There are over two million rivers inRussia, the biggest rivers are the Volga, the Yenisei, the Ob, the Lena and the Amur. Lake Baikal is the deepest lake in the world.The Russian Federation is very rich in mineral resources, such as oil, natural gas, coal, iron, copper, gold and others.
Russia is a Presidential republic. The legislative powers are exercised by the Dumaand the Council of Federation.The executive power belongs to the Cabinet of Ministers headed by the Prime Minister.The judicial power belongs to the system of Courts. The national symbols of the Russian Federation are a white-blue-red banner and a double-headed eagle.The population of Russia is about 140 million people. The capital of the Russian Federation is Moscow. It is the largest political, administrative, scientific,economic, educational and cultural center of the country.The place where we live is Zabaikaliye or Zabaikalsky territory. It is situated in Eastern Siberia and is the link between Siberia and the Russian Far East. The climate of our region is sharp-continental with sunny and hot summers and severe, snowless winters. The fauna of Zabaikaliye is very rich. We can find the bear, the wolf, the deer, the fox, the sable and other mammals of the taiga. There are several mineral springs in our region, such as the Kuka, the Molokovka and the Darasun. They are very curative.The principal industries on the Zabaikalsky territoryare mining, timber and wood-processing, engineering, food and light industries. The region is very rich in deposits of ferrous and non-ferrous metals, gold, molybdenum, beryllium, polymetallic ore, coal, graphite, magnetic ores, uranium and radon springs.Ore deposits are found in the Chara Zone, the Chinei Zone and the Kruchininskoye. Other mineral reserves include gold (Taseevskoye, Baleiskoye), lead-zinc (Klichka), copper (Udokan),molybdenum (Zhereken), tin (Sherlovaya Gora).The largest enterprise of Zabaikaliye is the locomotive-repair plant in Chita. We can find many small and large timber enterprises in our region, because woodlands cover almost half of the total territory.Agriculture is an important part of our region’s economy. Wheat, barley, rye, potatoes, cucumbers, carrots and cabbages are grown here. The main branches of agriculture are dairy, pig farming, sheepbreeding. There are big cattle-breeding farms producing pork, fowl and eggs.Nowadays the cultural life of the region is also many-sided and rich.There are many professional and amateur cultural associations, libraries, museums, cinemas, theatres and clubs in the region.The citizens are proud of their artists, sculptors, actors, singers and musicians.The region is international, and its inhabitants face neither national, nor ethnic and religious conflicts.The centre of Zabaikaliye is Chita. At the end of the nineteenth century the Trans-Siberian railway was constructed, and thus Chita
became an important transportation centre. Now its population is about 400 000 people.There are some enterprises in the town: the locomotive repair plant, the foot-wear factory, the fur-and-leather processing factory, the wood-working factory and others.The town has several higher educational institutions: ZabaikalskyState University, the Medical Academy, the Railway Transport Institute, the Agricultural Institute, the Economic Academy,The Zabaikalsky Institute of Entrepreneurshipand others.There are many cultural establishments in Chita, including cinema halls, clubs, two theatres (drama and puppet-show), dancing halls for young people, 11 museums.
