My cherished dream is to visit Great Britain someday. At our English lessons we often "travel" throughout this country. There are a lot of wonderful sights there. And I would like to see everything with my own eyes.

And if I had such opportunity , first of all I would go to London to walk along the streets and hear the English speech and, I hope , that I would understand, what the English are speaking about . And, of course, I would try to communicate with them in their native language.

Then I would go to the Buckingham palace to see the real Queen there. I am sure she is as kind as my grandmother! And, of course, I would admire the Changing of the Guard. One day I saw this wonderful show on TV!

After that I would visit the London Tower and feed the ravens. They say, if the ravens fly away, the Tower will ruin?! Is it true?!Returning home, I would buy souvenirs to all my relatives and friends. And as for me the trip to Great Britain would be the greatest gift!
