текс:Dear Lilly, Yesterday morning we went up on the London Eye and had a good view of London from there. In the afternoon we went to the Old Vic! It one of the most famous theatres in London. Of course, it is not as famous as the Royal Opera that is in Covent Garden, but there are many talented actors and actresses of the National Theatre Company there, too. We saw a pantomime Sleeping Beauty'. They usually put on pantomimes for children in December and January. This one was a musical comedy based on the story about Sleeping Beauty. We enjoyed music, beautiful scenery and wonderful dancing as well as some funny tricks. Say hello to Johnand Terry. Bye, Chris

Dear Mum and Dad, This morning we went to the Zoo in Regent's Park, and we've just been to 'the Odeon', one of the biggest cinemas in London. It has got ten screens and can show around ten films three times a day. Tickets in London are very expensive but this cinema is popularwith celebrities'. Most of the famous large cinemas are in the area around Leicester l'lestə] Square. Popular films with British teenagers are cartoons (especially Disney), police films, westerns, adventure films and romantic films. We were watching Shrek'. I was impressed by computer special effects, which made everything look like real. Kisses, Mary
