Измените текст так, что бы рассказчик говорил в настоящем времени.
New Year is my favourite holiday.We celebrate it on the 31st of December.
This year I celebrated New Year with my family. On New Year Eve we bought a New Year tree and decorated it with coloured balls and bright lights. We bought presents for our friends and relatives. My mother and I cooked a holiday supper. We made tasty salads, chicken, potatoes and mushrooms. We made a holiday cake, too. We bought a lot of fruit and sweets. We decorated our house with flakes and toys and put beautiful candles on the fireplace. We put a nice tablecloth, place and cups on the table.
Our guests came to visit us in the evening. They gave me wonderful presents. My aunt gave me a teddy bear as a present. My uncle`s present for me was a beautiful doll.
Then Father Frost came to our place. He was so funny! He had a big bag of presents. I told him a poem about winter, and he gave me a computer game as a present.
At last New Year came! We congratulated our dearest and nearest and wished them a Happy New Year! We enjoyed food and drinks. We danced, sang songs and played. I played the guitar. We had a good time together.
New Year was a merry and a happy holiday. I liked it very much.
