Помогите пожалуйста корректно перевести текст!
The United Kingdom of Great Britain and Northern Ireland is situated on the British Isles lying to the north-west of Europe .The British Isles consist of two large islands, Great Britain and Ireland, and some five thousand small islands. The country is usually called simply Great Britain.

The United Kingdom is one of the world’s smaller countries (it is twice smaller than France or Spain), with an area of some 244,110 sq. km.

The United Kingdom is made up of four parts: England, Wales, Scotland and Northern Ireland. Their capitals are London, Cardiff, Edinburgh and Belfast respectively. Great Britain consists of England, Scotland and Wales and doesn’t include Northern Ireland. The capital of the UK is London.

Great Britain is separated from the European continent by the North Sea and the English Channel, the narrower part of which is called the Strait of Dover. From the west the UK is washed by the Atlantic Ocean, from the east by the stormy North Sea and the southern coast is washed by the English Channel. The Irish Sea lies between England and Ireland.

The climate, in general, is mild, chilly, and often wet. Rain or overcast skies can be expected for up to 300 days per year. These conditions make Britain lush and green, known for a variety of scenery found on such a small area: a low-lying land and hilly areas, flat fields as well as lofty mountains. The surface of Eastern England is flat. Scotland and Wales are hilly and mountainous. The mountains are not very high as compared with those of the world, the loftiest one - Ben Nevis (Scotland) - is only 4400 feet (1343m) in height. In the west the Cambrian Mountains occupy the greater part of Wales; in the north - the Cheviot Hills separate England from Scotland, the Pennines - to the south of the Cheviot Hills and Cumbrian Mountains are famous for the number and beauty of their lakes. There are sixteen lakes here and this part of the country, called the Lake District, is the most beautiful and the wettest part of Great Britain.

There are many rivers in Britain but very few of them are navigable except near the mouth for anything but smaller vessels. Many of the rivers have been connected with each other by means of canals. The principal rivers are the Severn, the Thames and the Trent. The Severn is the longest river in Britain but the Thames is the most important one. The Severn is 210 miles in length, the Thames is a little over 200 miles.

The seas surrounding the British Isles are shallow - usually less than 300 feet deep. The shallowness is in some way an advantage. Shallow water is warmer than deep water and helps to keep the shores from extreme cold. It is too the home of plenty of fish, a million tons of which are caught every year. Britain’s coastline contains numerous harbours serving as convenient ports, among which are London, Liverpool, Glasgow, Portsmouth and others.

Britain has the richest energy sources in the European Union (EU), and its abundant resources of oil and natural gas which were discovered in the North Sea off the eastern coast of Britain in 1969 are of vital importance to the British economy. Britain also has a number of nuclear energy facilities. Recently much research has been devoted to developing biofuels, solar energy, wind power, and waterpower.

The population of Great Britain (1996 estimate) is 58,489,975. The largest cities in Great Britain are London, Birmingham, Manchester, Sheffield, Leeds and Glasgow.

Great Britain is highly developed economically, preeminent in the arts and sciences, sophisticated in technology, and highly prosperous and peaceful. In general, British subjects belong to one of the more affluent states of Europe and enjoy a high standard of living compared to the rest of the world.
