What holidays do only americans celebrate?

Ятак думаю тебе нужен перевод: какие праздники  празднуют  только американцы?  

one day, a few years ago, a train was travelling through the english countryside. this was in the days when trains had small compartments. in one compartment there were four people :   a young girl, quite pretty  ;   an old lady  ;   an army officer in his mid-thirties and  a young cockney, ever ready to have joke.  suddenly the train went into a tunnel. the lights had not been put on, so for half a minute the carriage was in complete darkness. and suddenly  came the sound of a large kiss followed almost immediately by a loud slap. when  it was light again in the carriage,  the officer was  with a bleeding nose and swollen eye. the old lady  thought to herself that the  young lady was very brave, because she had  dared to hit the officer for stealing a kiss in such a cowardly way. and the young girl  thought, that the officer should kiss the old lady, not her. the poor officer  thought to himself, that  cockney was  quite a clever chap who had  kissed the girl, and the girl had  hit the officer. and the cockney laughed to himself and  thought  that he was a  clever chap. he had  kissed the back of his  hand, had  hit the officer in the face and nobody had  said a word.

My favorite sport is cheerleading. it's a very unusual sport. it is very interesting too. if you want to be a good cheerleader, you have to be stretch, strong and slim. you also have to do a lot of acrobatic tricks. cheerleaders usually take part in a lot of competitions. there is the federation of cheerleading too. there are two kinds of the sport: "cheer" and "cheer-dance". they are the same, but there are some differences too. for example, in "cheer-dance" you may use any kinds of agitation, but in "cheer" you mustn't.
