Выпишите из текста прилагательные в превосходной степени со словами, к которым они относятся.

The United Kingdom of Great Britain and Northern Ireland is situated (расположено) on two large islands and about 5 thousand small islands to the North-West of Europe. They are called (называются) the British Isles.
The larger island is Great Britain which consists of three parts: England, Scotland and Wales, and the smaller is Ireland. Southern Ireland now is the Irish Republic, it is independent of the United Kingdom. The British Isles cover an area of about 95 000 square miles. The English Channel separates Great Britain from the continent. The narrowest part of it is the Strait of Dover.
The Atlantic Ocean, the North Sea, the Irish Sea wash the country. The shallow waters of the North and Irish Seas provide good fishing grounds. Fishing therefore is very important.
Mountains are an important feature of the geography of the country. There are mountain chains in Scotland, Wales and North-West England, but they are not very high. North-West England is also famous for its beautiful lakes.
The rivers of Great Britain are not very long but usually deep and never freeze in winter. The longest and deepest rivers are the Severn and Mersey, the Thames on which stands the capital of Great Britain — London. Britain has a mild temperate climate. The climate of the British Isles is generally cool, temperate, though in the Highlands of Scotland it is severe. The best season for the English people is spring when everything is in full bloom, there is much sunshine and it is rather warm. Autumn and winter are famous for their fogs and rains. In big industrial cities fog turns into "smog" (smoke+fog). It is a very unpleasant time. The usual temperature in winter very seldom falls below 3-5 degrees Centigrade. The weather in Great Britain is very changeable, there may be all kinds of weather within one day, that is why practically every talk the English people begin with comments on the weather.
Britain is a state with a highly developed industry. It is one of the most powerful capitalist countries in Europe. Great Britain is also one of the largest exporters of manufactured goods. At the same time it imports metal, oil, grain, meat, fruit, tea and other raw materials and foodstuffs.
