My favourite holiday is the New Year's Day. On this day we have a beautifully decorated New Year tree at home. There are many goodies on the table. We have guests on this holiday or we go to visit our friends or relatives ourselves. I love the New Year's Eve. I dance, sing, get presents and have fun on this day. Sometimes I can go for a walk with my friends. We like to make a snowman in the yard. We don't go to bed to see the New Year in, and to watch New Year's shows on TV. This holiday happens only once a year. So I'm waiting for it each time and I love it a lot!

Мой любимый праздник - Новый Год. В этот день у нас дома стоит красиво украшенная новогодняя елка. На столе много вкусностей. У нас в этот праздник бывают гости или мы сами едем в гости к друзьям или к родственникам. Я люблю канун Нового Года. Я танцую, пою, получаю подарки и веселюсь в этот день. Иногда я могу прогуляться с друзьями. Нам нравится лепить снеговика во дворе. Мы долго не ложимся спать, встречаем Новый год и смотрим Новогодние передачи по телевизору. Этот праздник бывает только раз в году. Так что я жду его каждый раз, и я люблю его очень!
