On New Year's Eve, I decorate the Christmas tree, help my mother set the table, decorate the house.

Объяснение:

перевод:Новый год - замечательный зимний праздник. В новогоднюю ночь всё кажется таинственным, сказочным и волшебным.

Я люблю Новый год за то, что именно в это время случаются чудеса и сбываются мечты. Это семейный праздник. В Новый год я наряжаю ёлку маме накрывать на стол, украшаю дом. В новогоднюю ночь люди выходят на улицу и любуются ярким и незабываемым зрелищем - салютом, который дарит всем приподнятое праздничное настроение. На встречу Нового года у нас дома собираются близкие родственники и любимые друзья, мы дарим друг другу подарки, танцуем возле нарядной ёлки и поем новогодние песни.
