last year my friends and i went to the mountains during our  holidays.    it was amazing. we went skiing and sledding a lot, we were playing snowballs and making a snowman. the weather was perfect: frost and sun, all the time we had to wear  sunglasses as in summer.    in the evening we decided to  have dinner in the hotel restaurant and had fun. after dinner we went to our rooms which  were cosy and bright. so  jacek was  playing the guitar, anna was  singing, i was chatting with my parents, max and alice were watching a funny movie, and martha was playing her favourite computer games.  everybody was relaxing. it was great.  then everybody wanted a drink of tea and veronica brought her thermos. we poured tea in the mugs, the tea was hot and fragrant. but we couldn't drink it, because it was salted!   it turned out that in the morning veronica was afraid to be late, she hurried and confused salt and sugar! everyone laughed. it was really fun.  then we came to the night cafe  on the nineth floor and drank sweet  tea there.  i will remember that salt tea all my life!

sports play a very important part in our life.it helps people to keep fit,to be healthy and strong.not all people go in for sports.but many people swim,play different games,ski or skate just for pleasure.
