текст:
Speaker 1 Last night, when we were passing by the Cathedral of … what's its name?… Oh yes, Christ the Saviour, we were really impressed not only by its appearance - which was beautiful!… There was a huge crowd of people standing around waiting and we were lucky enough to join them when after a few minutes a concert started… The music was divine!… The musicians played some classical and, some, I guess, spiritual music and the whole event was dedicated to Moscow's jubilee.

Speaker 2 Last time I was in Moscow, it was early in July … it was rather warm … very much like in my country. I liked Moscow and the Muscovites and had a great time here. I made some new friends - they're students too, very nice guys. I promised to come in winter, for the Christmas holidays. And here I am. But the weather is awful! I have to wear a warm coat and I don't like it… Last night, my Russian friends took me to the Vorobyovy Hills. They wanted to go to Red Square at first, but I refused. I don't fancy crowds, you know…

Speaker 3 When we arrived in Moscow last May, the first thing that caught my eye was the fact that people in the street were wearing those striped ribbons, I guess they were black and orange, yes, I am sure, they were black and orange… And these ribbons were everywhere - fixed to peoples' clothes, handbags, even cars! We asked each other what they were for but nobody knew. Then, when the guide came, she explained that it was a new tradition and told us the whole story. It's amazing!

Speaker 4 I must say that the day was great, the weather was great and the food was great too! It was a real holiday! As it's my first year at the university, I haven't had a party like that before. First, the rector came with a huge bowl of some hot drink and started to give it out to the students. Hmm, I really enjoyed it … Unusual but quite good! It was followed by pancakes and some pies… Then there was music and dances, and… we laughed a lot…

Speaker 5 What really impressed me in Moscow was the orthodox festival in Kolomenskoye. Oh, I can't forget those delicious pancakes, they call them "blini",… with a lot of butter and sour cream … not good for your health though … but I couldn't resist them … And the events, of course. It was as if I was taken back a few centuries into the past - all those bears, puppets, and snow forts! People wearing national clothes … and a huge straw doll, they burnt it in the end… These celebrations are usually held in …
