Like other people,I have my own opinion.So today I will tell it to you.I think that Great Britain is called Great,not just for a beautiful name or to show tourists that it is just great.UK is a gorgeous country.British people are so different.Some brits prefer , modern technologies, but some of them have a little house in a small village and they are happy because they like country and quite life.All of them are so industrious,but they don't forget about family!
People in the UK honor their family traditions and I think it's great.So I can easily say that the word GREAT in the name of this powerful country isn't only a word,this country is really GREAT!

Перевод:
Как и у других людей,у меня есть свое мнение.Так что сегодня я его вам поведаю.Я считаю что Великобритания называется Великой, не просто так чтобы красиво преподнести туристам и завлечь их .Великобритания великолепная страна.Британцы такие разные.Некоторые британцы предпочитают современные технологии,а некоторые из них имеют маленькие домики в небольших деревушках и они счастливы потому что им нравится загородная и спокойная жизнь.Все они такие работящие,но при этом не забывают о семье.Люди в Великобритании чтят свои семейные традиции и я считаю это Великим делом.И так я могу без труда сказать что слово ВЕЛИКИЙ в названии этой сильнейшей страны не просто слово,эта страна действительно ВЕЛИКАЯ!

A friend who lived in Australia (was told) one day by his neighbour living across the road that he (would be away) in England for a few weeks. The man further explained that his house (was being decorated) at the moment but he (was leaving) the country the next day, as he (had not seen) his rich relative for a few years. He said he hoped his neighbour (would look) after his house properly. The first week passed without any incident. Soon the decorators packed up and (left). But the next day the good friend (caught) sight of two fellows at his neighbour's door (packing) rolled up carpets into the old van. "Hey", cried the man, "What the hell are you (doing)? I (have been looking) after the house for a week already an I (do not want) my friend (to get) angry when he (returns) home" The two fellows explained to him that the owner of that very house (had ordered) (to clean) his Persian carpets while he (was away). They managed to make him (believe) that it (was) true. The friendly man (thought) that his own carpets (needed) cleaning. He had always (been) a bachelor and everything in his house (suffered) from his carelessness. So he (agreed) with the two fellows that they (add) the expenses secretly to his neighbour's bill. The happy carpet-cleaners (laid) all the carpets into their van and (drove) cheerfully away. While they (were driving) they (made) fun of the man they had so cleverly (deceived). There (is) no need to say the neither of the neighbours had ever (seen) their carpets again.
