Кто хорошо знает английский! помогите найти ошибки в тексте.

London would not be London without the River Thames. It flows 215 miles across the English, it reaches the sea.

The Thames provided a major highway between London and many parts of the country. London was protected from sea attacks because they built castles and forts at the mouth of the river.

With the industrial Revolution in the 18th century , the Thames become one of the busiest waterways in the world.

Today the Thames has become a symbol of London, just as much as Big Ben or Buckingham Palace. You can admire bridges built in many different architectural styles. The most famous one is probably Tower Bridge Or you might be lucky enough to see London's rowing event, the Oxford and cambridge Boat Race. the Thames will always have something to offer you.
