переведите пж Manchester began when a wooden fort was built by the Roman army on a plateau about 80 AD. The fort was rebuilt in stone about 200 AD. Soon a civilian settlement grew up around the fort.

In the 7th century the Saxons created a new village, but it was tiny. The surrounding area was thinly populated and was mostly forest. The Saxons called any Roman town or fort a caester. They called the old fort at Manchester Mamm caester. The village nearby took its name from the fort. By 1086 the settlement was called Mamecester. In time the namechanged to Manchester. In 919 the

king repaired the old Roman fort as

a defence against the Danes.

In the early 19th century

Manchester became world famous

as a manufacturing centre. Wool,

silk and cotton were manufactured

and vast numbers of working people

worked 12 hour days in the mills.

There was also a paper making

industry and iron foundries.

Manchester University was founded in 1903. The central library was built in 1934.

Today Manchester is a large city and it is situated in the Northwest of England. It stands on the River Iiwell, which is a tributary of the Mersey River. Manchester is one of the major ports in England. It was famous for its wool and cotton industries but now it is the financial and business centre. When Britain was an Empire, Manchester was called a Cottonpoiis for its cotton mills in the city and in the small towns around it.

Manchester can also be proud of its Business School, which is the best in Britain. Music industry also develops in Manchester, many pop and rock bands play in nightclubs.

Everybody knows Manchester’s two football teams — Manchester United and Manchester City.

In general Manchester forms the opinion of a beautiful city, but unfortunately many of its old buildings were destroyed by the Irish Republican Army bombing in 1996. It was an illegal military organisation which wanted Northern Ireland to leave the UK and become part of the Irish Republic. In 1996 the city centre was ruined by IRA bombs but it was rebuilt. The phoenix rose from the ashes.

Короче становился день.

О создании СПб и переносе в него столицы Росси русские ученые и писатели высказывали разное мнение. А. И. Герцен писал: «Любимое дите царя, отрекшегося от своей страны для её пользы и угнетавшего её во имя европеизма и цивилизации». К. С. Аксаков в стихотворении «Петру I» высказывал противоположную мысль:
Откинул ты Москву жестоко,
И от народа ты вдали
Построил город одинокий-
Вы вместе жить уж не могли…
Попытайтесь привести доводы в пользу каждой из этих двух точек зрения.
