Переведите пожалуйста.
1)in this city a lot of people gather in Times Square and watch the “Big Apple” fall. “Big Fall” isn’t a real apple. It’s a moving picture of an apple on the side of one of the big buildings in Times Square. Every New Year’s Eve during the last few seconds before midnight it starts to “fall” down the building, and when it gets to the bottom it’s the start of the new year.
2)In this country housewives start cooking special food for New Year’s Day and all the members of the family do a big cleaning. The idea is to get rid of the dirt of the past year, and welcome the New Year without it. On the television or radio you can hear 108 bells. The 108th bell rings just a second before the midnight. The people say: “Happy New Year!” people eat special food and drink rice wine during the meal.
3)People call the New Year’s Eve “Hogmanay”. They visit their friends’ houses just after midnight of the New Year’s night. The first person who comes to your house brings you luck. At midnight when the clock begins to strike 12, the head of the family goes to the entrance door, opens it wide and holds it until the last stroke. Then he shuts the door. He has let the old year out and let the New Year in.
4)This country is sometimes called “the upside down world”. It lies in the Southern Hemisphere. During the Christmas holidays people often sunbathe on the beach or swim and surf in the ocean. On the 31st of December many people got to the country for the picnic. In January the temperatures are fron 20 to 30 above zero or higher.
5)In this country it can be dangerous to have a walk at night at the end of December. People usually throw the old things from the house through the window: broken cups and plates, old clothes and boots and sometimes different pieces of furniture. People believe that on the New Year’s Eve the magician Befaniya comes to the houses through the chimney and put the presents for children in their stockings or shoes.
