At last the winter holidays came! i was very happy!     i didn't have   to get up early in the morning and run to school. i could stay in the bed till midday. but i didn't want to sleep. there were a lot of things to do. the weather was fine so my friends and i went to the skating- rink almost every day. it was fun! then i spent a week in the country where my grandfather and grandmother lived. it was great. i drank milk and eat a lot of tasty food which my granny prepared for me. i have many friends in this village because i go there every holidays. we went to the forest to ski, we made snowmen and played snowballs. we even played hockey! but the winter holidays were over and i returned to the city again.  i liked my holidays very much.   наконец наступили зимние каникулы! я был счастлив!   я не должен был вставать рано утром и бежать в школу. я мог   оставаться в постели до полудня. но я не хотел спать. было так много дел. погода была хорошая, так что мои друзья и я ходили на каток почти каждый день. это было весело! затем я провел неделю в деревне, где   живут  мои дедушка и бабушка  . это было здорово. я пил молоко и ел много вкусной пищи, которую моя бабушка готовила для меня. у меня много друзей в этой деревне, потому что я езжу туда каждые каникулы. мы ходили в лес кататься на лыжах, мы делали снеговиков и играли в снежки. мы даже играли в хоккей! но зимние каникулы закончились, и я вернулся в город снова. мне понравились мои каникулы.
