Нужен перевод пожалуйста. Welcome to Great Britain!
What are the first words you remember of when thinking about Great Britain?
I know from my own experience,people usually say some popular words: the Royal
family, a foggy island, old castles, red buses, football and tea. Some of you will picture Big
Ben orthe Tower Bridge, but Great Britain is not only a number of symbols... It is a real
country with its own geography, economy and special political system, a rich culture and
different sporting events.
Today I begin my story with some interest- ing facts about my country.
The climate here is rather cool and changeable but it often rains which is good for plants.
The British love their green gardens full of beautiful flowers. Great Britain is rich in
gardens and parks which are famous all over the world.
Great Britain is half the size of France or Spain, but the English language is the first
language of international communication in the world. By the way, if you visit Scotland
one day, you may have some trouble understanding people there. it is because they
have a strong accent which can be difficult to understand.
Now, girls and boys, you know some new interesting facts about Britain.
i hope this was enjoyable.
